Operating materials

Vehicle features and options

This chapter describes model-specific equipment, systems, and functions that are currently available, or may become available in the future, even if they are not present in the vehicle.

Additional information:

Vehicle equipment.

Fuel recommendation

General information

Depending on the region, many filling stations sell fuel that has been customized to winter or summer conditions. Fuel that is available in winter, for instance helps make a cold start easier.

Gasoline

General information

For the best fuel efficiency, the gasoline should be sulfur-free or very low in sulfur content.

Fuels that are marked on the gas pump as containing metal must not be used.

Fuels with a maximum ethanol content of 10 %, i.e., E10, may be used for refueling.

The power and consumption specifications refer to operating with RON 98 E10 fuel

When using minimum quality AKI 87 fuel, there may be knocking noises as well as driving and acoustic abnormalities. These have no effect on the engine service life.

Safety information

Observe fuel quality

Use suitable fuel only

Do not refuel with gasoline that does not comply with the minimum quality

Do not use a refuel with a higher ethanol content

Recommended gas quality

BMW recommends AKI 93.

Minimum fuel grade

BMW recommends AKI 91.

If you use gasoline with this minimum AKI Rating, the engine may produce knocking sounds when starting at high external temperatures. This has no effect on the engine life.

Engine oil

General information

The engine oil consumption and engine oil properties depend on the driving style and operating conditions.

Therefore, regularly check the engine oil level after refueling by taking a detailed measurement.

The engine oil consumption can increase in the following situations, for instance:

Sporty driving style.

Break-in of the engine.

Idle operation of the engine.

With use of engine oil types that are not recommended.

Different Check Control messages are shown on the control display depending on the engine oil level and engine oil properties.

The vehicle manufacturer recommends having the engine oil changed by an authorized service center or another qualified service center or repair shop. The suitable viscosity grade is indicated on a sign in the engine compartment.

Safety information

Add engine oil immediately

Do not add too much engine oil

Change engine oil promptly

Electronic oil measurement

General information

The electronic oil measurement has two measuring principles:

Monitoring.

Detailed measurement.

When making frequent short-distance trips or using a sporty driving style, for instance when cornering aggressively, regularly perform a detailed measurement.

Monitoring

Principle

The engine oil level is monitored electronically while driving and can be shown on the control display.

If the engine oil level is outside its permissible operating range, a Check Control message is displayed.

Functional requirements

A current measured value is available after approx. 30 minutes of normal driving.

Displaying the engine oil level

Apps menu

"Vehicle"

"Vehicle status"

"Engine oil level"

The engine oil level is displayed.

System limits

When making frequent short-distance trips or using a sporty driving style, it may not be possible to calculate a measured value. In this case, the measured value for the last, sufficiently long trip is displayed.

Detailed measurement

Principle

The engine oil level is checked when the vehicle is stationary and displayed via a scale.

If the engine oil level is outside its permissible operating range, a Check Control message is displayed.

General information

During the measurement, the idle speed is increased somewhat.

Functional requirements

Vehicle is parked in a horizontal position.

The drive-ready state is switched on by pressing the Start/Stop button.

The engine is at operating temperature.

Selector lever in selector lever position N or P and accelerator pedal not depressed.

Performing a detailed measurement

Apps menu

"Vehicle"

"Vehicle status"

"Engine oil level"

"Oil level measurement"

"Start measurement"

The engine oil level is checked and displayed via a scale.

Adding engine oil

General information

Only add engine oil when the message is displayed in the instrument cluster. The top-up quantity is indicated in the message shown on the control display.

Only add suitable types of engine oil.

Safely park the vehicle and switch off drive-ready state before adding engine oil.

Take care not to add too much engine oil.

Safety information

Observe when using operating fluids

Add engine oil immediately

Do not add too much engine oil

Overview

The oil filler neck is located in the engine compartment.

Additional information:

For an overview.

Adding engine oil

Opening the hood.

Opening.

Open the lid counterclockwise.

Add engine oil.

Close the lid.

Engine oil types to add

General information

The engine oil grade is critical for the service life of the engine.

Only add with the types of engine oil which are listed.

Safety information

Do not use oil additives

Observe correct viscosity grade

Suitable engine oil types

When topping up engine oil, the following oil specification applies:

Gasoline engine

BMW Longlife-01 FE.

BMW Longlife-19 FE.

Alternative engine oil types

If an engine oil suitable for continuous use is not available, up to 1 US quart/liter of an engine oil with the following oil rating can be added:

Oil specification

API SL.

API SM.

API SN.

Viscosity grades

When selecting an engine oil, make sure that the engine oil has a suitable viscosity grade. The suitable viscosity grade is indicated on a sign in the engine compartment.

More information about suitable oil specifications and engine oil viscosity grades can be requested from an authorized service center or another qualified service center or repair shop.

Coolant

General information

Coolant consists of water and coolant additive.

Not all commercially available coolant additives are suitable for the vehicle. The vehicle manufacturer recommends using coolant with the BMW LC-18 specification. Do not mix coolant additives of different colors. Use a 50:50 mixing ratio of water to coolant additive. Information on suitable coolant additives can be provided by an authorized service center or another qualified service center or repair shop.

Safety information

Only open the cooling system with the engine cooled down

Use suitable additives only

Observing the mixture ratio

Coolant level

General information

The coolant may be overfilled in the coolant reservoir when the vehicle is delivered from the factory. Run longer to achieve the normal coolant level.

The nominal coolant level is indicated by the maximum mark in the filler neck of the coolant reservoir.

Additional information:

For an overview.

Checking the coolant level

Let the engine cool down.

Opening the hood.

Opening.

Turn the lid of the coolant reservoir slightly counterclockwise to allow any excess pressure to dissipate, then open it.

Open the coolant reservoir lid.

The coolant level is correct when it is just below the maximum mark in the filler neck.

Close the lid.

Adding coolant

Let the engine cool down.

Opening the hood.

Opening.

Turn the lid of the coolant reservoir slightly counterclockwise to allow any excess pressure to dissipate, then open it.

Open the coolant reservoir lid.

If the coolant is low, slowly add coolant up to the specified fill level; do not overfill.

Close the lid.

Have the cause of the coolant loss eliminated as soon as possible.

Disposal

Comply with the relevant environmental protection regulations when disposing of coolant and coolant additives.

Washer fluid

General information

All spray nozzles are supplied from one tank.

Use a mixture of tap water and windshield washer concentrate. If desired, a windshield washer concentrate containing antifreeze can be used.

Recommended minimum fill quantity: 0.4 US gal/2 liters.

Safety information

Observe with antifreeze for washer fluid

Observe when filling the washer fluid

Do not use silicon-containing additives

Observe when mixing additives

Overview

The washer fluid reservoir is located in the engine compartment.

Malfunction

The use of undiluted windshield washer fluid concentrate or alcohol-based antifreeze can lead to incorrect readings at temperatures below +5 ℉/-15 ℃.
