Engine oil consumption

A certain amount of engine oil will be consumed while driving. In the following situations, oil consumption may increase, and engine oil may need to be refilled in between oil maintenance intervals.

When the engine is new, for example directly after purchasing the vehicle or after replacing the engine

If low quality oil or oil of an inappropriate viscosity is used

When driving at high engine speeds or with a heavy load, when towing, or when driving while accelerating or decelerating frequently

When leaving the engine idling for a long time, or when driving frequently through heavy traffic

Reservoir cap “FULL” line “LOW” line

If the level is on or below the “LOW” line, add coolant up to the “FULL” line. (P. 529)

Coolant selection

Only use “Toyota Super Long Life Coolant” or a similar high quality ethylene glycol based non-silicate, non-amine, non-nitrite, and non-borate coolant with long-life hybrid organic acid technology.

U.S.A.:

“Toyota Super Long Life Coolant” is a mixture of 50% coolant and 50% deion- ized water. (Minimum temperature: -31°F [-35°C])

Canada:

“Toyota Super Long Life Coolant” is a mixture of 55% coolant and 45% deion- ized water. (Minimum temperature: -44°F [-42°C])

For more details about coolant, contact your Toyota dealer.

If the coolant level drops within a short time of replenishing

Visually check the radiator, hoses, engine coolant reservoir cap, drain cock and water pump.

If you cannot find a leak, have your Toyota dealer test the cap and check for leaks in the cooling system.

Checking fluid level

The brake fluid level should be between the “MAX” and “MIN” lines on the tank.

Adding fluid

Make sure to check the fluid type and prepare the necessary item.

Fluid type	FMVSS No.116 DOT 3 or SAE J1703 brake fluid
Items	Clean funnel

Brake fluid can absorb moisture from the air

Excess moisture in the brake fluid can cause a dangerous loss of braking effi- ciency. Use only newly opened brake fluid.

Check the battery as follows:

Battery exterior

Make sure that the battery terminals are not corroded and that there are no loose connections, cracks, or loose clamps.

Terminals

Hold-down clamp

Before recharging

When recharging, the battery produces hydrogen gas which is flammable and explosive. Therefore, observe the following before recharging:

If recharging with the battery installed on the vehicle, be sure to disconnect the ground cable.

Make sure the power switch on the charger is off when connecting and dis- connecting the charger cables to the battery.

After recharging/reconnecting the battery (vehicles with a smart key sys- tem)

The engine may not start. Follow the procedure below to initialize the system.

1 Shift the shift lever to P.

2 Open and close any of the doors.

3 Restart the engine.

Unlocking the doors using the smart key system may not be possible imme- diately after reconnecting the battery. If this happens, use the wireless remote control or the mechanical key to lock/unlock the doors.

Start the engine with the engine switch in ACC. The engine may not start when the engine switch turned from off. However, the engine will operate normally from the second attempt.

The engine switch mode is recorded by the vehicle. If the battery is recon- nected, the vehicle will return the engine switch mode to the status it was in before the battery was disconnected. Make sure to turn off the engine before disconnect the battery. Take extra care when connecting the battery if the engine switch mode prior to discharge is unknown.

If the system will not start even after multiple attempts, contact your Toyota dealer.

WARNING

Chemicals in the battery

Batteries contain poisonous and corrosive sulfuric acid and may produce hydrogen gas which is flammable and explosive. To reduce the risk of death or serious injury, take the following precautions while working on or near battery:

Do not cause sparks by touching the battery terminals with tools.

Do not smoke or light a match near the battery.

Avoid contact with eyes, skin and clothes.

Never inhale or swallow electrolyte.

Wear protective safety glasses when working near the battery.

Keep children away from the battery.

Where to safely charge the battery

Always charge the battery in an open area. Do not charge the battery in a garage or closed room where there is insufficient ventilation.

How to recharge the battery

Only perform a slow charge (5 A or less). The battery may explode if charged at a quicker rate.

Emergency measures regarding electrolyte

If electrolyte gets in your eyes

Flush your eyes with clean water for at least 15 minutes and get immedi- ate medical attention. If possible, continue to apply water with a sponge or cloth while traveling to the nearest medical facility.

If electrolyte gets on your skin

Wash the affected area thoroughly. If you feel pain or burning, get medical attention immediately.

If electrolyte gets on your clothes

It can soak through clothing on to your skin. Immediately take off the cloth- ing and follow the procedure above if necessary.

If you accidentally swallow electrolyte

Drink a large quantity of water or milk. Get emergency medical attention immediately.

situations:

A washer does not work.

The warning message appears on the display.

Check if the treadwear indicators are showing on the tires. Also check the tires for uneven wear, such as excessive wear on one side of the tread.

Check the spare tire condition and pressure if not rotated.

1 New tread Worn tread

Treadwear indicator

The location of treadwear indicators is shown by a “TWI” or “” mark, etc., molded into the sidewall of each tire.

Replace the tires if the treadwear indicators are showing on a tire.

Rotate the tires in the order

shown.

To equalize tire wear and extend tire life, Toyota recommends that tire rotation is carried out at the same interval as tire inspection.

Do not fail to initialize the tire pressure warning system after tire rotation.

Your vehicle is equipped with a tire pressure warning system that uses tire pressure warning valves and transmitters to detect low tire infla- tion pressure before serious problems arise.

The tire pressure detected by the tire pressure warning sys- tem can be displayed on the multi-information display.

If the tire pressure drops below a predetermined level, the driver is warned by a screen display and a warning light.

Installing tire pressure warning valves and transmitters

When replacing tires or wheels, tire pressure warning valves and transmitters must also be installed.

When new tire pressure warning valves and transmitters are installed, new ID codes must be registered in the tire pressure warning computer and the tire pressure warning system must be initialized.

Initializing the tire pressure warning system

The tire pressure warning system must be initialized in the fol- lowing circumstances:

When rotating the tires.

When the tire inflation pressure is changed such as when chang- ing tire size. (When there are multiple specified pressures)

After registering the ID codes. (P. 429)

When the tire pressure warning system is initialized, the current tire inflation pressure is set as the benchmark pressure.

How to initialize the tire pressure warning system

Park the vehicle in a safe place and turn the engine switch off.

Initialization cannot be performed while the vehicle is moving. Adjust the tire inflation pressure to the specified cold tire inflation pressure level. (P. 548)

Make sure to adjust the tire pressure to the specified cold tire infla- tion pressure level. The tire pressure warning system will operate based on this pressure level.

Turn the engine switch to ON.

Press and hold the tire pres- sure warning reset switch until the tire pressure warn- ing light blinks 3 times.

A message is displayed on the multi-information display. Also, “--” is displayed for inflation pressure of each tire on the multi-information display while the tire pressure warning sys- tem determines the position.

Drive straight (with occasional left and right turns) at approxi- mately 25 mph (40 km/h) or more for approximately 10 to 30 min- utes.

Initialization is complete when the position of each tire is determined and the inflation pressure of each tire is displayed on the multi-infor- mation display.

Initialization may take longer than approximately 30 minutes in cer- tain situations, such as when the vehicle is stopped for a long time at traffic lights, etc. (P. 434)

Registering ID codes

Every tire pressure warning valve and transmitter has a unique ID code. When replacing a tire pressure warning valve and transmitter, it is necessary to register the ID codes.

To register the ID codes, perform the following procedure:

Press the tire pressure warn- ing reset switch 3 times until the tire pressure warning light blinks slowly 3 times.

Then a message will be dis- played on multi-information display. When registration is being performed, the tire pres- sure warning light will blink for approximately 1 minute then illuminate and “--” will be dis- played for the inflation pres- sure of each tire on the multi- information display.

Drive straight (with occasional left and right turns) at approxi- mately 25 mph (40 km/h) or more for approximately 10 to 30 min- utes.

Registration is complete when the tire pressure warning light turns off and the inflation pressure of each tire is displayed on the multi-information display.

Registration may take longer than approximately 30 minutes in certain situations, such as when the vehicle is stopped for a long time at traffic lights, etc. (P. 434)

After registering the ID codes, make sure to initialize the tire pressure warning system. (P. 427)

When to replace your vehicle’s tires

Tires should be replaced if:

The treadwear indicators are showing on a tire.

You have tire damage such as cuts, splits, cracks deep enough to expose the fabric, and bulges indicating internal damage

A tire goes flat repeatedly or cannot be properly repaired due to the size or location of a cut or other damage

If you are not sure, consult with your Toyota dealer.

When replacing the tires and wheels

If the ID code of the tire pressure warning valve and transmitter is not reg- istered, the tire pressure warning system will not work properly. After driv- ing for about 20 minutes, the tire pressure warning light blinks for 1 minute and stays on to indicate a system malfunction.

Tire life

Any tire over 6 years old must be checked by a qualified technician even if it has seldom or never been used or damage is not obvious.

Routine tire inflation pressure checks

The tire pressure warning system does not replace routine tire inflation pressure checks. Make sure to check tire inflation pressure as part of your routine of daily vehicle checks.

Maximum load of tire

Check that the number given by dividing the maximum load by 1.10 of the replacement tire is greater than 1/2 of the Gross Axle Weight Ratings (GAWR) of either the front axle or the rear axle, whichever is greater.

For the GAWR, see the Certification Label. For the maximum load of the tire, see the load limit at maximum cold tire inflation pressure mentioned on the sidewall of the tire. (P. 554)

Tire types

Summer tires

Summer tires are high-speed performance tires best suited to highway driving under dry conditions. Since summer tires do not have the same traction performance as snow tires, summer tires are inadequate for driving on snow-covered or icy roads. For driving on snow-covered roads or icy roads, the use of snow tires is recommended. When install- ing snow tires, be sure to replace all four tires.

All season tires

All season tires are designed to provide better traction in snow and to be adequate for driving in most winter conditions as well as for use year-round. All season tires, however, do not have adequate traction performance compared with snow tires in heavy or loose snow. Also, all season tires fall short in acceleration and handling performance com- pared with summer tires in highway driving.

Snow tires

For driving on snow-covered roads or icy roads, we recommend using snow tires. If you need snow tires, select tires of the same size, con- struction and load capacity as the originally installed tires. Since your vehicle has radial tires as original equipment, make sure your snow tires also have radial construction. Do not install studded tires without first checking local regulations for possible restrictions. Snow tires should be installed on all wheels. (P. 331)

Initializing the tire pressure warning system

Initialize the system with the tire inflation pressure adjusted to the speci- fied level.

If the tread on snow tires wears down below 0.16 in. (4 mm)

The effectiveness of the tires as snow tires is lost.

Situations in which the tire pressure warning system may not oper- ate properly

In the following cases, the tire pressure warning system may not operate properly.

If non-genuine Toyota wheels are used.

A tire has been replaced with a tire that is not an OE (Original Equip- ment) tire.

A tire has been replaced with a tire that is not of the specified size.

Tire chains, etc., are equipped.

An auxiliary-supported run-flat tire is equipped.

If a window tint that affects the radio wave signals is installed.

If there is a lot of snow or ice on the vehicle, particularly around the wheels or wheel housings.

If the tire inflation pressure is extremely higher than the specified level.

If wheel without the tire pressure warning valve and tranmitter is used.

If the ID code on the tire pressure warning valves and transmitter is not registered in the tire pressure warning computer.

Performance may be affected in the following situations.

Near a TV tower, electric power plant, gas station, radio station, large display, airport or other facility that generates strong radio waves or electrical noise

When carrying a portable radio, cellular phone, cordless phone or other wireless communication device

If tire position information is not correctly displayed due to the radio wave conditions, the display may be corrected by driving and changing the radio wave conditions.

When the vehicle is parked, the time taken for the warning to start or go off could be extended.

When tire inflation pressure declines rapidly for example when a tire has burst, the warning may not function.

The initialization operation

Make sure to carry out initialization after adjusting the tire inflation pres- sure.

Also, make sure the tires are cold before carrying out initialization or tire inflation pressure adjustment.

If you have accidentally turned the engine switch off during initialization, it is not necessary to press the reset switch again as initialization will restart automatically when the engine switch has been turned to ON for the next time.

If you accidentally press the reset switch when initialization is not neces- sary, adjust the tire inflation pressure to the specified level when the tires are cold, and conduct initialization again.

While the position of each tire is being determined and the inflation pres- sures are not being displayed on the multi-information display, if the inflation pressure of a tire drops, the tire pressure warning light will come on.

Warning performance of the tire pressure warning system

The warning of the tire pressure warning system will change in accor- dance with the conditions under which it was initialized. For this reason, the system may give a warning even if the tire pressure does not reach a low enough level, or if the pressure is higher than the pressure that was adjusted to when the system was initialized.

When initialization of the tire pressure warning system has failed Initialization may take longer to complete if the vehicle is driven on an unpaved road. When performing initialization, drive on a paved road if possible. Depending on the driving environment and condition of the tires,

initialization will be completed in approximately 10 to 30 minutes. If initial- ization is not complete after driving approximately 10 to 30 minutes, con- tinue driving for a while.

If the inflation pressure of each tire is not displayed after driving for approximately 1 hour, perform the following procedure.

Park the vehicle in a safe place for approximately 20 minutes. Then drive straight (with occasional left and right turns) at approximately 25 mph (40 km/h) or more for approximately 10 to 30 minutes.

However, in the following situations, the tire inflation pressure will not be recorded and the system will not operate properly. Perform initialization again.

When operating the tire pressure warning reset switch, the tire pressure warning light does not blink 3 times.

After performing initialization, the tire pressure warning light blinks for 1 minute then stays on while driving about 20 minutes.

If the inflation pressure of each tire is still not displayed, have the vehicle inspected by your Toyota dealer.

WARNING

When inspecting or replacing tires

Observe the following precautions to prevent accidents.

Failure to do so may cause damage to parts of the drive train as well as dangerous handling characteristics, which may lead to an accident resulting in death or serious injury.

Do not mix tires of different makes, models or tread patterns. Also, do not mix tires of remarkably different treadwear.

Do not use tire sizes other than those recommended by Toyota.

Do not mix differently constructed tires (radial, bias-belted or bias-ply tires).

Do not mix summer, all season and snow tires.

Do not use tires that have been used on another vehicle.

Do not use tires if you do not know how they were used previously.

When initializing the tire pressure warning system

Do not operate the tire pressure warning reset switch without first adjusting the tire inflation pressure to the specified level. Otherwise, the tire pressure warning light may not come on even if the tire inflation pressure is low, or it may come on when the tire inflation pressure is actually normal.

NOTICE

Repairing or replacing tires, wheels, tire pressure warning valves, transmitters and tire valve caps

When removing or fitting the wheels, tires or the tire pressure warning valves and transmitters, contact your Toyota dealer as the tire pres- sure warning valves and transmitters may be damaged if not handled correctly.

Make sure to install the tire valve caps. If the tire valve caps are not installed, water could enter the tire pressure warning valves and the tire pressure warning valves could be bound.

When replacing tire valve caps, do not use tire valve caps other than those specified. The cap may become stuck.

To avoid damage to the tire pressure warning valves and transmit- ters

When a tire is repaired with liquid sealants, the tire pressure warning valve and transmitter may not operate properly. If a liquid sealant is used, contact your Toyota dealer or other qualified service shop as soon as possible. Make sure to replace the tire pressure warning valve and transmitter when replacing the tire. (P. 427)

Driving on rough roads

Take particular care when driving on roads with loose surfaces or pot- holes.

These conditions may cause losses in tire inflation pressure, reducing the cushioning ability of the tires. In addition, driving on rough roads may cause damage to the tires themselves, as well as the vehicle’s wheels and body.

If tire inflation pressure of each tire becomes low while driving

Do not continue driving, or your tires and/or wheels may be ruined.

The recommended cold tire infla- tion pressure and tire size are dis- played on the tire and loading information label. (P. 548)

1 Tire valve

Tire pressure gauge

Remove the tire valve cap.

Press the tip of the tire pressure gauge onto the tire valve. Read the pressure using the gauge gradations.

If the tire inflation pressure is not at the recommended level, adjust the pressure.

If you add too much air, press the center of the valve to deflate.

After completing the tire inflation pressure measurement and adjustment, apply soapy water to the valve and check for leakage.

Put the tire valve cap back on.

Tire inflation pressure check interval

You should check tire inflation pressure every two weeks, or at least once a month.

Do not forget to check the spare.

Effects of incorrect tire inflation pressure

Driving with incorrect tire inflation pressure may result in the following:

Reduced fuel economy

Reduced driving comfort and poor handling

Reduced tire life due to wear

Reduced safety

Damage to the drive train

If a tire needs frequent inflating, have it checked by your Toyota dealer.

Instructions for checking tire inflation pressure

When checking tire inflation pressure, observe the following:

Check only when the tires are cold.

If your vehicle has been parked for at least 3 hours or has not been driven for more than 1 mile or 1.5 km, you will get an accurate cold tire inflation pressure reading.

Always use a tire pressure gauge.

It is difficult to judge if a tire is properly inflated based only on its appear- ance.

It is normal for the tire inflation pressure to be higher after driving as heat is generated in the tire. Do not reduce tire inflation pressure after driving.

Passengers and luggage weight should be placed so that the vehicle is balanced.

When replacing wheels, care should be taken to ensure that they are equivalent to those removed in load capacity, diameter, rim width and inset*.

Replacement wheels are available at your Toyota dealer.

*: Conventionally referred to as “offset”.

Toyota does not recommend using the following:

Wheels of different sizes or types

Used wheels

Bent wheels that have been straightened

Use only Toyota wheel nuts and wrenches designed for use with your aluminum wheels.

When rotating, repairing or changing your tires, check that the wheel nuts are still tight after driving 1000 miles (1600 km).

Be careful not to damage the aluminum wheels when using tire chains.

Use only Toyota genuine balance weights or equivalent and a plas- tic or rubber hammer when balancing your wheels.

When replacing wheels

The wheels of your vehicle are equipped with tire pressure warning valves and transmitters that allow the tire pressure warning system to provide advance warning in the event of a loss in tire inflation pressure. Whenever wheels are replaced, tire pressure warning valves and trans- mitters must be installed. (P. 427)

When installing the wheel ornament (on some models)

Align the notch of the wheel and orna- ment.

WARNING

When replacing wheels

Do not use wheels that are a different size from those recommended in the Owner’s Manual, as this may result in a loss of handling control.

Never use an inner tube in a leaking wheel which is designed for a tubeless tire. Doing so may result in an accident, causing death or seri- ous injury.

When installing the wheel nuts

Be sure to install the wheel nuts with the tapered ends facing inward. (P. 515) Installing the nuts with the tapered ends facing outward can cause the wheel to break and eventually cause the wheel to come off while driving, which could lead to an accident resulting in death or seri- ous injury.

Never use oil or grease on the wheel bolts or wheel nuts.

Oil and grease may cause the wheel nuts to be excessively tightened, leading to bolt or disc wheel damage. In addition, the oil or grease can cause the wheel nuts to loosen and the wheel may fall off, causing an accident and resulting in death or serious injury. Remove any oil or grease from the wheel bolts or wheel nuts.

Open the glove box.

Remove the tray.

Remove the cover by sliding up while pulling toward you.

Remove the filter cover.

Pull the filter out of the filter out- let.

Remove the air conditioning filter and replace it with a new one.
