Winter operation

The onset of winter is often accompa-

nied by rapid changes in weather.

Adaptations in driving style should be

accompanied 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 con-

tains the year-round ratio of 50:50

water and extended-duty antifreeze/

corrosion protection. This mixture pro-

vides protection against freezing down

to approx. – 34 7 (– 37 6). 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 its use, 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.

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).

For best performance, deactivate the

DSC when snow chains are mounted.

Refer to page 79.

Starting off

When starting from a full stop in deep

snow or for "rocking" the vehicle to free

it, we recommend that you deactivate

the DSC system. Refer to page 79.

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. On down-

grades or slopes, shift down to the next

lower gear at an early point. Maintain an

adequate distance between yourself

and the car ahead.

Brakes

Winter road conditions substantially re-

duce the traction available between the

tires and the road surface. Remember

that braking distances will be signifi-

cantly 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.

Following that, increase pedal pressure

again. Reduce the pressure as the

wheels lock, then reapply pressure.

Repeat this procedure. This type of

staggered braking will reduce the brak-

ing distance, and the vehicle still re-

mains responsive to steering. It allows

you to steer around hazards once you

have reduced the pressure on the brake

pedal.
