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 page172.
M+S
Winter and all-season tires.
These have better winter properties than sum-
mer tires.
Tire condition
Inspect your tires frequently for tread wear,
signs of damage and foreign objects lodged in
the tread, and check the tread depth.
Minimum tread depth
The tread depth should not drop below 0.12 in/
3 mm, although, for example, European legisla-
tion only specifies a minimum tread depth of
0.063 in/1.6 mm.
At tread depths below 0.12 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.
Winter tires noticeably loose their suitability for
winter use below a tread depth of 0.16 in/4 mm. New tires should be mounted in the interest of
safety.
Wear indicators at the tread-groove base, refer
to arrow, are distributed over the tire's circum-
ference and are marked on the side of the tire
with TWI – Tread Wear Indicator. If the indica-
tors are at the level of the profile, the legal per-
missible tread depth of 0.063 in/1.6 mm has
been reached.
Tire damage
Due to low-profile tires, please note that
wheels, tires and suspension parts are
more susceptible to road hazard and conse-
quential damages.
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. These
kinds of problems may also be signaled by other
changes in vehicle response, such as a strong
tendency to pull to the left or right.
In these cases reduce your speed immediately
and have the wheels and tires inspected imme-
diately. To do this, carefully drive to the next
BMW center or a specialized tire dealer which
works with personnel trained in accordance
with BMW specifications. Have the vehicle
towed to the workshop if necessary.
Tire damage can be extremely dangerous to
vehicle occupants and other road users.<
Unprofessional attempts by laymen to
service tires can lead to damage and acci-
dents. Have this work performed by skilled pro-
fessionals only. The technicians at your BMW
center will be glad to assist you with the
required professional knowledge and special-
ized equipment.<

Wheels and tires
172
Run-flat tires
You will recognize run-flat tires by the circular
symbol containing the letters RSC on the side-
wall.
Run-flat tires consist of self-contained tires and
special rims. The sidewall reinforcement
ensures that the tire retains some residual
safety in the event of pressure drop and driving
remains possible to a restricted degree.
New wheels and tires
Only have new wheels and tires mounted
by a BMW center or a specialized tire
dealer which works with personnel trained in
accordance with BMW specifications. If this
work is performed inexpertly, there is a danger
of damage and associated safety risks. Make
sure that the new wheels are balanced.<
Retreaded tires
BMW does not recommend the use of
retread tires, as otherwise driving safety
may be reduced. Possible variations in the
design and the age – which could be substan-
tial – of the carcasses can lead to more rapid
wear.<
The right wheels and tires
If you switch from summer to winter tires, or
vice versa, use run-flat tires, as in the event of a
flat tire there is no spare tire available. Your
BMW center will be glad to advise you.
For safety reasons, BMW recommends
that you do not have damaged run-flat
tires repaired; they should be replaced. wheel and tire combinations that BMW
has tested and approved for your particular
vehicle. Variations in factors such as manufac-
turing tolerances mean that even wheels and
tires with identical official size ratings could
actually have different dimensions than the
approved units – these differences could lead to
body contact, and with it the risk of severe acci-
dents. If non-approved wheels and tires are
used, BMW cannot evaluate their suitability,
and therefore cannot be held liable for driving
safety.<
You can find out the right wheel-tire combina-
tion from your BMW center.
The right wheel-and-tire combination is
another vital factor in ensuring reliable opera-
tion of various vehicle systems such as ABS
and DSC.
To maintain good handling and vehicle
response, use only tires of a single tread config-
uration from a single manufacturer. After a flat
tire, always remember to have the specified
wheel and tire combination remounted on the
vehicle as soon as possible.
Recommended tire brands
BMW tests certain tire brands for each tire size,
classifies them as road-safe and approves
them. Consult your BMW center for more infor-
mation. Observe any country-specific regula-
tions, e.g. on making a corresponding entry in
the vehicle documents.
The factory-mounted tires have been specially
selected to provide optimized performance
when installed on your vehicle; if properly cared
for, they will provide a combination of safety and
excellent ride comfort.
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.

Run-flat tires
If you switch from summer to winter tires, or
vice versa, use run-flat tires, refer to page172,
as in the event of a flat tire there is no spare tire
available. Your BMW center will be glad to
advise you.
Watch speed
Observe the permissible maximum speed
for the respective winter tires, as other-
wise tire damage and occur and cause acci-
dents.<
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 side wall
of the tire.
Snow chains*
BMW only tests certain fine-link snow chains,
classifies them as road-safe and approves
them. Consult your BMW center for more infor-
mation. BMW recommends using these
approved snow chains. These snow chains are
approved exclusively for use in pairs on the rear
wheels with the tire size:
>245/50 R 17 Y
>245/45 R 18 Y
Observe the chain manufacturer's instructions
when mounting snow chains. Do not exceed a
vehicle speed of 30 mph/50 km/h with the
chains mounted.
Do not initialize the Flat Tire Monitor after
mounting snow chains.
When you are driving with snow chains, it can
be beneficial to switch off DTC briefly, refer to
page82.<

1.Push a screwdriver from the left under the
lamp and lever up the lamp to the right.
2.Turn the bulb holder 905 to the left and
remove.
3.Remove and replace the bulb.
LEDs Light-emitting diodes
Light-emitting diodes installed behind translu-
cent lenses serve as the light source for many of
the controls and displays in your vehicle. These
light-emitting diodes, which operate using a
concept similar to that applied in conventional
lasers, are officially designated as Class 1 light-
emitting diodes.
Do not remove the covers, and never
stare into the unfiltered light several
hours, as irritation of the retina could result.<
Changing a wheel
Your BMW is equipped with run-flat tires as
standard. An immediate wheel change in the
event of a flat tire is therefore no longer
required.
You will recognize run-flat tires by a circular
symbol containing the letters RSC on the side
of the tire, refer to Run-flat tires on page171.
If you have new tires mounted or switch from
summer to winter tires, or vice versa, use run-
flat tires, as in the event of a flat tire there is no
spare tire available. Your BMW center will be
glad to advise you.
Also refer to New wheels and tires, page172.
Car jacking points
The jacking points for the car jack are located in
the positions shown.
The suitable tools for changing tires are
available as accessories from your BMW
center.<
Vehicle battery
Battery care
The battery is 100 % maintenance-free, i.e., 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 battery
Only charge the battery in the vehicle via the
terminals in the engine compartment with the
engine switched off. For the connections, refer
to Jump starting on page186.
Disposal
After replacement, have old batteries dis-
posed of by your BMW center or deposit
them at a recycling center. Maintain the battery
in an upright position for transport and storage.
Always secure the battery to prevent it from tip-
ping over during transport.<
