Super Premium Gasoline/AKI 91

This gasoline is highly recommended.

However, you may also use gasoline with less

AKI. The minimum AKI Rating is:

> 128i: 87

If you use gasoline with this minimum AKI Rat-

ing, the engine may produce knocking sounds

when starting at high outside temperatures.

This has no effect on the engine life.

Do not use any gasoline below the speci-

fied minimum fuel grade. Otherwise, the

engine could be damaged.<

Use high-quality brands

Field experience has indicated significant dif-

ferences in fuel quality: volatility, composition,

additives, etc., among gasolines offered for sale

in the United States and Canada. Fuels contain-

ing up to and including 10Ξ ethanol or other

oxygenates with up to 2.8Ξ oxygen by weight,

that is, 15Ξ MTBE or 3Ξ methanol plus an

equivalent amount of cosolvent, will not void the

applicable warranties with respect to defects in

materials or workmanship.

The use of poor-quality fuels may result in

drivability, starting and stalling problems

especially under certain environmental condi-

tions such as high ambient temperature and

high altitude.

Should you encounter drivability problems

which you suspect could be related to the fuel

you are using, we recommend that you respond

by switching to a recognized high-quality brand

such as gasoline that is advertised as Top Tier

Detergent Gasoline.

has tested and approved for your particular

tires with identical official size ratings could

actually have different dimensions, which could

Pay attention to speed

Always comply with the speed limit for the

winter tires mounted on your car; failure

to do so could result in tire damage and acci-

dents.<

If the car is capable of speeds higher than that

permitted for the winter tires, a label stating the

maximum permitted speed for the mounted

tires must be displayed in your field of view.

Specialist tire dealers and your BMW center

can supply these labels.

Storage

Store wheels and tires in a cool, dry place with

as little exposure to light as possible. Always

protect tires against all contact with oil, grease

and fuels.

Do not exceed the maximum tire inflation pres-

sure indicated on the sidewall of the tire.

Swapping wheels between axles

BMW advises against swapping wheels

between the front and rear axles, even if all tires

have the same size, as this could impair driving

characteristics. If the tires are of mixed sizes,

swapping wheels between the axles is not per-

missible.

Snow chains*

Only certain fine-link snow chains have been

tested by BMW, classified as safe for use and

recommended. Consult your BMW center for

more information. Snow chains must be

Checking oil level

Your car is equipped with an electronic oil-level

monitor.

For precise measurement and display of the oil

level, the engine must be at operating tempera-

uninterrupted driving. You can have the oil level
