Winter operationThe 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.CoolantBe 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.LocksBMW 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 offWe 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 
surfacesUse 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.
BrakesWinter 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.

Wheel and tire combinations The right choice Use only BMW-approved tires, refer to 
page 117. 
Due to the high speeds this vehicle can 
achieve, the use of specific tire brands, 
specifications and dimensions is man-
datory.
Consult any BMW center for details. 
Comply with local/national regulations.
The correct wheel/tire combinaton 
affects different sytems, such as 
ABS, ATC, DSC. The function of these 
systems can be impaired if the correct 
combinaton is not used.
Therefore, only use tires of the same 
brand and tread pattern. Replace a flat 
tire with an approved wheel/tire combi-
nation as soon as possible.<
Codes on the tires and wheels The tire codes will aid you in selecting 
the correct tire. 
Codes on radial tires:
The speed rating indicates the ap-
proved maximum speed for the tire.
Summer tires:
S = up to 112 mph (180 km/h)
T = up to 118 mph (190 km/h)
H = up to 130 mph (210 km/h)
V = up to 150 mph (240 km/h)
W = up to 167 mph (270 km/h)
Y = above 167 mph (270 km/h)
ZR = above 150 mph (240 km/h) Example:
Nominal width 
in mm
Aspect ratio in % 
Radial tire code
Rim diameter in inches
Load rating
(not on ZR tires)
Speed rating
(before R on ZR tires)
225/50 R
1692W
Winter tires:
Q M+S = up to 100 mph (160 km/h)
T M+S = up to 118 mph (190 km/h)
H M+S = up to 130 mph (210 km/h)
Codes stamped on light-alloy wheels:
Protect valve inserts against dirt using 
screw-on valve stem caps. Dirt in the 
valves frequently leads to slow leaks. Example:
Rim width 
in inches
Code letter for
flange type
Symbol for full-drop 
center rim
Rim diameter in inches

Winter tiresChoosing the right tireBMW recommends winter tires (M+S 
radial tires) for driving in adverse winter 
road conditions. Although all-season 
M+S tires provide better winter traction 
than standard summer tires with H, V, 
W, Y and ZR speed ratings, they gener-
ally fail to provide the same levels of 
performance as standard snow tires in 
winter driving. 
For of safe tracking and steering re-
sponse, install winter tires made by the 
same manufacturer having the same 
tread configuration on all four wheels.
Mount only winter tires approved by 
BMW. Any BMW center will be glad to 
provide you with information on the 
best winter tires for your particular driv-
ing conditions.Never exceed the maximum speed 
for that the tires are rated.
Unprofessional attempts by laymen to 
service tires can lead to damage and 
accidents.
Have this work performed by skilled 
professionals only. Your BMW center 
will be glad to assist you with both their 
expertise and the proper equipment for 
your vehicle.<
Tire condition, tire pressureWinter tires display a perceptible loss in 
their ability to cope with winter driving 
conditions once the tread wears to be-
low 0.16 in (4 mm), and should thus be 
replaced.
Comply with the specified tire inflation 
pressures – and be sure to have the 
wheel and tire assemblies balanced 
every time you change the tires.
StorageStore tires in a cool, dry place, away 
from light whenever possible. Protect 
the tires against contact with oil, grease 
and fuel.Snow chains
*
Use narrow-link BMW snow chains on 
summer or winter tires only in pairs and 
only on the rear wheels. Comply with all 
manufacturer's safety precautions when 
mounting the chains.
