Temperature
The temperature grades are A, the highest, B,
and C, representing the tire's resistance to the
generation of heat and its ability to dissipate
heat when tested under controlled conditions
on a specified indoor laboratory test wheel.
Sustained high temperature can cause the
material of the tire to degenerate and reduce
tire life, and excessive temperature can lead to
sudden tire failure. The grade C corresponds to
a level of performance which all passenger car
tires must meet under the Federal Motor Vehi-
cle Safety Standard No. 109. Grades B and A
represent higher levels of performance on the
laboratory test wheel than the minimum
required by law.
The temperature grade for this tire is
established for a tire that is properly
inflated and not overloaded. Excessive speed,
underinflation, or excessive loading, either sep-
arately or in combination, can cause heat
buildup and possible tire failure.<
RSC – Run-Flat Tires
You will recognize Run-Flat Tires by a circular
symbol containing the letters RSC on the side
of the tire, refer to page116.
M+S
Winter and all-season tires.
These have better winter properties than sum-
mer tires.
XL
Designation for specially reinforced tires.
Tire condition
Inspect your tires frequently for tread wear,
signs of damage and for foreign objects lodged
in the tread. Check the tread depth.
Minimum tread depth
The tread depth should not drop below 1/8 in/
3 mm, although, for example, European legisla-
tion only specifies a minimum tread depth of 1/16 in/1.6 mm. At tread depths below 1/8 in/
3 mm there is an increased risk of high-speed
hydroplaning, even when only small amounts of
water are present on the road surface.
When winter tires wear down past a tread depth
of 1/6 in/4 mm, they become perceptibly less
suitable for winter conditions. In the interest of
safety, new tires should be installed.
Wear indicators in the base of the tread groove
are distributed around the tire's circumference;
the letters TWI, for Tread Wear Indicator, on the
tire's sidewalls identify tires that incorporate
these wear indicators. Once the tire tread has
worn down to the wear indicators, the tire has
worn to a depth of 1/16 in/1.6 mm.
Wheel/tire damage
Please note that low-profile tires cause wheels,
tires and suspension parts to be more suscep-
tible to road hazard and consequential dam-
ages.
Unusual vibrations encountered during normal
vehicle operation can indicate tire failure or
some other vehicle defect. This can, for exam-
ple, be caused by driving over curbs. The same
applies to any other abnormal road behavior,
such as pulling severely to the right or left.
In these cases, reduce speed immedi-
ately and have wheels and tires thor-
oughly checked. To do so, drive carefully to the
nearest BMW Center or tire shop that works
according to BMW repair procedures with cor-
respondingly trained personnel. If necessary,
have the vehicle towed there.
Tire damage can be extremely dangerous for
vehicle occupants and other road users.<

Run-Flat Tires
When mounting new tires or changing over
from summer to winter tires and vice versa,
mount Run-Flat Tires for your own safety. In the
event of a flat, moreover, no spare wheel is
available. Your BMW Center will be glad to
advise you.
For safety reasons, BMW recommends
that damaged Run-Flat Tires be replaced
rather than repaired.<
Special characteristics of winter tires
BMW recommends winter tires for use in cold
winter driving conditions. Although all-season
M+S tires provide better winter traction than
summer tires, they generally fail to provide the
same levels of cold-weather performance as
winter tires.
Pay attention to speed
Always comply with the speed limit for the
winter tires mounted on your car; failure
to do so could result in tire damage and acci-
dents.<
If the car is capable of speeds higher than that
permitted for the winter tires, a label stating the
maximum permitted speed for the mounted
tires must be displayed in your field of view.
Specialist tire dealers and your BMW Center
can supply these labels.
Storage
Always store wheels and tires in a cool, dry
place with as little exposure to light as possible.
Always protect tires against all contact with oil,
grease and fuels. Do not exceed the maximum
tire inflation pressure indicated on the sidewall
of the tire.
Snow chains*
Only certain fine-link snow chains have been
tested by BMW, classified as safe for use and
recommended. Consult your BMW Center for
more information. Attach snow chains in pairs
and only to the rear wheels. Observe the manu-facturer's instructions when mounting snow
chains. Do not exceed a speed of 30 mph or
50 km/h.
You are not permitted to mount snow chains to
tires of the following sizes:
>255/40 R 17
>255/35 R 18
>255/30 R 19
Do not initialize the Flat Tire Monitor if
snow chains are mounted, otherwise the
instrument might issue an incorrect reading.
When driving with snow chains, you may find it
helpful to activate DTC temporarily, refer to
page68.<

according to BMW repair procedures with cor-
respondingly trained personnel.
Changing wheels
Your BMW is equipped with Run-Flat Tires as
standard. This removes the need to change a
wheel immediately in the event of a puncture.
The symbol identifying Run-Flat Tires is a circle
with the letters RSC on the sidewall, refer to
Run-Flat Tires, page116.
When mounting new tires or changing over
from summer to winter tires and vice versa,
mount Run-Flat Tires for your own safety. In the
event of a flat, moreover, no spare wheel is
available. Your BMW Center will be glad to
advise you. Refer also to New wheels and tires,
page116.
The tools for changing wheels are avail-
able as optional accessories from your
BMW Center.<
Jack mounting points
The jacking points are at the positions shown in
the illustration.
Vehicle battery
Battery care
The battery is 100 % maintenance-free, the
electrolyte will last for the life of the battery
when the vehicle is operated in a temperate cli-
mate. Your BMW Center will be glad to advise in
all matters concerning the battery.
Charging the battery
Only charge the battery in the vehicle via the
terminals in the engine compartment with the
engine off. Connections, refer to Jump starting
on page132.
Disposal
Have old batteries disposed of by your
BMW Center or hand them in to a recy-
cling center. Maintain the battery in an upright
position for transport and storage. Always
secure the battery against tipping over during
transport.<
Power failure
After a temporary power loss, the functioning of
some equipment may be limited and require ini-
tialization. Individual settings may likewise have
been lost and will have to be reprogrammed:
>Time and date
These values must be updated, refer to
page64.
>Radio
Stations must be stored again, refer to the
separate Owner's Manual for Radio.
>Seat and mirror memory
The positions must be stored again, refer to
page35.
>Inside rearview mirror with digital compass
The system must be calibrated, refer to
page88.
Fuses
Never attempt to repair a blown fuse and
do not replace a defective fuse with a sub-
stitute of another color or amperage rating, oth-
erwise this could lead to a circuit overload, ulti-
mately resulting in a fire in the vehicle.<
