Maintenance and care

    Working from top to bottom, liberally apply water to the vehicle body, wheel wells and underside of the vehicle to remove any dirt and dust.
    Wash the vehicle body using a sponge or soft cloth, such as a chamois.
    For hard-to-remove marks, use car wash soap and rinse thoroughly with water.
    Wipe away any water.
    Wax the vehicle when the waterproof coating deterio- rates.

If water does not bead on a clean surface, apply wax when the vehi- cle body is cool.

    Automatic car washes
    Fold the mirrors before washing the vehicle. Start washing from the front of the vehicle. Make sure to extend the mirrors before driving.
    Brushes used in automatic car washes may scratch the vehicle surface, parts (wheel, etc.) and harm your vehicle’s paint.
    Vehicles with a rear spoiler: In cer- tain automatic car washes, the

rear spoiler may interfere with machine operation. This may pre- vent the vehicle from being cleaned properly or result in dam- age to the rear spoiler.

    High pressure car washes

As water may enter the cabin, do not bring the nozzle tip near the gaps around the doors or perimeter of the windows, or spray these areas continuously.

    When using a car wash (vehi- cles with a smart key system)

If the door handle becomes wet while the electronic key is within the effective range, the door may lock and unlock repeatedly. In that case, follow the following correction pro- cedures to wash the vehicle:

    Place the key in a position 6 ft. (2

m) or more separate from the vehicle while the vehicle is being washed. (Take care to ensure that the key is not stolen.)

    Set the electronic key to bat- tery-saving mode to disable the smart key system. (P.126)
    Wheels and wheel ornaments
    Remove any dirt immediately by using a neutral detergent.
    Wash detergent off with water immediately after use.
    To protect the paint from damage, make sure to observe the follow- ing precautions.
    Do not use acidic, alkaline or abrasive detergent
    Do not use hard brushes
    Do not use detergent on the wheels when they are hot, such as after driving or parking in hot weather
    Bumpers and side moldings

Do not scrub with abrasive cleaners.

    Plated portions

If dirt cannot be removed, clean the parts as follows:

    Use a soft cloth dampened with an approximately 5% solution of neu- tral detergent and water to clean the dirt off.
    Wipe the surface with a dry, soft cloth to remove any remaining moisture.
    To remove oily deposits, use alco- hol wet wipes or a similar product.

NOTICE

    When using a high pressure car wash
    When washing the vehicle, do not spray the camera or its sur- rounding area directly with a high pressure washer. Shock applied from high pressure water may cause the device to not operate normally.
    Do not bring the nozzle tip close to boots (rubber or resin manu- factured cover), connectors or the following parts. The parts may be damaged if they come into contact with high-pressure water.
    Traction related parts
    Steering parts
    Suspension parts
    Brake parts
    Keep the cleaning nozzle at least 11.9 in. (30 cm) away from the vehicles body. Otherwise resin section, such as moldings and bumpers, may be deformed and damaged. Also, do not con- tinuously hold the nozzle in the same place.
    Do not spray the lower part of the windshield continuously. If water enters the air conditioning system intake located near the lower part of the windshield, the air conditioning system may not operate correctly.

    Remove dirt and dust using a vacuum cleaner. Wipe dirty surfaces with a cloth damp- ened with lukewarm water.
    If dirt cannot be removed, wipe it off with a soft cloth dampened with neutral deter- gent diluted to approximately 1%.

Wring out any excess water from the cloth and thoroughly wipe off remaining traces of detergent and water.

    Shampooing the carpets

There are several commercial foam- ing-type cleaners available. Use a sponge or brush to apply the foam. Rub in overlapping circles. Do not use water. Wipe dirty surfaces and let them dry. Excellent results are obtained by keeping the carpet as dry as possible.

    Handling the seat belts

Clean with mild soap and lukewarm water using a cloth or sponge. Also check the belts periodically for excessive wear, fraying or cuts.

NOTICE

    Cleaning the inside of the rear window
    Do not use glass cleaner to clean the rear window, as this may cause damage to the rear window defogger heater wires or antenna. Use a cloth damp- ened with lukewarm water to gently wipe the window clean. Wipe the window in strokes run- ning parallel to the heater wires or antenna.
    Be careful not to scratch or damage the heater wires or antenna.

    Remove dirt using a

water-dampened soft cloth or synthetic chamois.

    Wipe the surface with a dry, soft cloth to remove any remaining moisture.

    Cleaning the areas with satin-finish metal accents

The metal areas use a layer of real metal for the surface. It is necessary to clean them regularly. If dirty areas are left uncleaned for long periods of time, they may be difficult to clean.

    Remove dirt and dust using a vacuum cleaner.
    Wipe off any excess dirt and dust with a soft cloth damp- ened with diluted detergent.

Use a diluted water solution of approximately 5% neutral wool detergent.

    Wring out any excess water from the cloth and thoroughly wipe off all remaining traces of detergent.
    Wipe the surface with a dry, soft cloth to remove any remaining moisture. Allow the leather to dry in a shaded and ventilated area.

    Caring for leather areas

Toyota recommends cleaning the interior of the vehicle at least twice a year to maintain the quality of the vehicle’s interior.

    Remove dirt and dust using a vacuum cleaner.
    Wipe it off with a soft cloth dampened with neutral deter- gent diluted to approximately 1%.
    Wring out any excess water from the cloth and thoroughly wipe off remaining traces of detergent and water.
