Snow chains
BMW snow chains
*
 can be fitted on 
both summer and winter tires in re-
sponse to severe winter road condi-
tions. Mount them in pairs on the rear 
wheels only, and be sure to comply with 
the manufacturer's safety instructions. 
Do not exceed a maximum speed of 
30 mph (50 km/h). In this situation 
(snow chains mounted), deactivate the 
ASC+T or DSC
*
.
Starting off
When starting off in deep snow or when 
rocking the car to free it, we recom-
mend that you switch the ASC+T or 
DSC
*
.
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. Maintain an ade-
quate distance between yourself and 
the car ahead.
Brakes
Winter road conditions substantially re-
duce the amount of traction available 
between the tires and the road surface; 
the resulting increases in braking dis-
tance are considerable and should be 
continually borne in mind.
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, etc. 
This type of staggered braking will re-
duce the braking distance, and the ve-
hicle still remains responsive to steer-
ing. 
You can then attempt to steer around 
hazards after you have reduced pres-
sure on the brake pedal.
Do not shift down on slick road 
surfaces. Doing so could cause 
the rear wheels to lose traction and 
skid, which could result in the loss of 
vehicle control.
