Overview

Winter operation

Winter is often accompanied by rapid
changes in weather. Adaptions in
driving style should be accompanied by
preparations on the vehicle itself to
ensure that your vehicle operates safely
and trouble-free throughout the winter
months.

Coolant

Be sure that the coolant mixture
contains the year-round ratio of 50:50
water and antifreeze/corrosion protec-
tion. This mixture will resist freezing 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 using the deicer, treatment with
BMW lock cylinder grease is recom-
mended.

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 tailgate 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 type of exceptional situation
where the snow chains are mounted,
deactivate the ASC+T/DSC. Refer to
page

BMW 325xi: in a worst-case scenario,
i.e. if your vehicle is stuck on one side
or you cannot access one tire, then only
one chain may be attached to a rear
wheel for a short period of time.

Starting off

When starting off from a full stop in
deep snow or when "rocking" the
vehicle to free it, it may be effective to
deactivate the ASC+T/DSC system for
a short period. Refer to page

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. Downshift
into the next lower gear on ascents or
descents. Maintain an adequate
distance between yourself and the
vehicle ahead.
