Winter operation

The onset of winter is often accompa-

nied by rapid changes in weather. Adap-

tations in driving style should be accom-

panied by preparations on the vehicle

itself to ensure that your progress

through the winter remains safe and

trouble-free.

Coolant

Be sure that the coolant mixture is kept

at the year-round ratio of 50:50 of water

and antifreeze/corrosion protection.

This mixture provides protection against

freezing down to approx. – 347

(– 376). Replace the coolant every four

years.

Locks

BMW door lock deicer can be used to

free them if frozen. This deicer also

contains lubricant.

After using deicer, treatment with BMW

lock barrel grease is recommended.

Rubber seals and components

To prevent the weather-stripping from

freezing, apply a spray-on rubber treat-

ment or silicone spray to the door, hood

and luggage compartment lid seals.

A full range of car-care products is

available from your BMW center.<

Snow chains

BMW snow chains* can be mounted on

both summer and winter tires. Mount

them in pairs on the rear wheels only

and comply with the manufacturer's

safety precautions. Do not exceed a

maximum speed of 30 mph (50 km/h).

In this situation (snow chains mounted),

deactivate the DSC. Refer to page 81.

Starting off

We recommend that you use the man-

ual control switch to deactivate DSC

when starting off in deep snow or when

rocking the car to free it (refer to

page 81).

Driving on low-traction road

surfaces

Use smooth, gentle pressure to control

the accelerator pedal. Avoid excessive

engine speeds and shift to the next

higher gear at an early point. Adapt

your speed and driving style when ap-

proaching grades or slopes. Maintain

an adequate distance between yourself

and the car ahead.

Brakes

Winter road conditions substantially

reduce the traction available between

the tires and the road surface.

Remember that braking distances will

be significantly longer as a result.

ABS is intended to prevent the wheels

from locking during brake applications,

thus helping to maintain vehicle stability

and steering response.

If the ABS does not respond in a critical

braking situation and the wheels lock:

Reduce the pressure on the brake

pedal until the wheels just start to roll

again while still maintaining enough

force to continue braking. Then in-

crease the pressure, reduce the pres-

sure when the wheels lock, reapply

pressure etc.

This staggered braking procedure will

reduce stopping distances while help-

ing you maintain steering control.

You can then attempt to steer around

hazards after you have reduced pres-

sure on the brake pedal.
