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 page200.
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 legis-
lation 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 inter-
est 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.
Otherwise, tire damage can pose a lethal hazard
to vehicle occupants and other road users.<

Wheels and tires
200
Run-flat tires
The symbol identifying run-flat tires is a circle
with the letters RSC on the sidewall.
Run-flat tires comprise a conditionally self-sup-
porting tire and a special rim. The reinforce-
ment in the sidewalls ensures that the tire can
continue to be used subject to certain restric-
tions, even if depressurized.
For information on continuing to drive with a flat
tire, refer to Indication of a flat tire on page83.
New wheels and tires
Have new wheels and tires installed only
by your BMW center or tire shop that
works according to BMW repair procedures
with correspondingly trained personnel. If this
work is not carried out properly, there is a dan-
ger of subsequent damage and related safety
h a z a r d s . M a k e s u re t h a t t h e n e w w h ee l s a r e b a l-
anced.<
Retreaded tires
BMW recommends that you do not use
retreaded tires, since driving safety may
be impaired. The causes for this include poten-
tially different tire casing structures and often
wide variations in tire age, which can result in a
limited service life.<
Correct wheels and 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, no spare wheel is available. Your
BMW center will be glad to advise you.BMW recommends that you use only
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, which could
lead to body contact and thus to severe acci-
dents. If non-approved wheels and tires are
used, BMW cannot evaluate their suitability,
and therefore cannot guarantee their driving
safety.<
You can inquire about the right wheel/tire com-
bination at your BMW center.
The correct combination of wheels and tires is
also necessary to ensure reliable operation of
various vehicle systems such as ABS, DSC or
FTM.
To maintain good handling and vehicle
response, use only tires of a single brand and
tread configuration. After a tire has been dam-
aged, mount the previous wheel and tire combi-
nation again as soon as possible.
Wheels with Tire Pressure Monitor
TPM electronics
When mounting new tires or changing over
from summer to winter tires, or vice versa, only
use wheels with TPM electronics; otherwise,
the Tire Pressure Monitor may not be able to
detect a puncture, refer to page85. Your BMW
center will be glad to advise you.
Recommended tire brands
Certain makes of tire are recommended by
BMW for each tire size. They are marked with a
clearly visible BMW designation on the sidewall
of the tire.

When properly used, these tires meet the high-
est standards in terms of safety and handling
characteristics.
Special characteristics of winter tires
BMW recommends winter tires for winter roads
or at temperatures below +457/+76.
Although all-season M+S tires provide better
winter traction than summer tires, they gener-
ally 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
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 pres-
sure indicated on the sidewall of the tire.
Swapping wheels between axles
BMW advises against swapping wheels
between the front and rear axles, even if all tires
have the same size, as this could impair driving
characteristics. If the tires are of mixed sizes,
swapping wheels between the axles is not per-
missible.
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. Snow chains must be
mounted in pairs and on the rear wheels only.
Observe the manufacturer's instructions when
mounting snow chains. Do not exceed a speed
of 30 mph/50 km/h with chains.
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
page81.<

Paintwork care
Regular care contributes to value retention and
protects the paintwork against the long-term
effects of damaging substances.
Region-specific environmental influences can
damage the vehicle paintwork. Therefore, it is
important to adapt the frequency and scope of
car care accordingly.
Immediately remove aggressive materials such
as spilled fuel, oil, grease, brake fluid, tree sap or
bird droppings to prevent damage to the paint-
work.
Repairing paintwork damage
Immediately repair scratches or similar
damage, such as that caused by stones
hitting the vehicle, where necessary to prevent
rusting.<
BMW recommends having paintwork damage
repaired by a professional paint repair work-
shop according to BMW specifications using
original BMW paint materials.
Preservation
A preservation treatment is necessary when
water no longer beads off the clean paintwork
surface. Only use products for paintwork pres-
ervation that contain carnauba or synthetic
waxes.
Rubber seals
Treat only with water or rubber care products.
Do not use silicon-containing care prod-
ucts on rubber seals; otherwise, noise
and damage could occur.<
Chrome parts
Carefully clean vehicle parts such as the radia-
tor grill, door handles or window frames with
copious quantities of water and a shampoo
additive, especially when roads are treated with
de-icing salt. For additional treatment, use a
chrome polish.
Light-alloy wheels
For technical reasons, dust is generated during
braking that is deposited on the light-alloy
wheels. Remove the dust regularly using acid-
free rim cleaner.
Do not use aggressive, acidic, strongly
alkaline and abrasive cleaning agents or
steam jets over 140 7/60 6; otherwise, damage
may occur.<
Outside sensors/cameras
Keep the sensors and cameras on the
outside of the vehicle, e.g. those for Park
Distance Control, clean and free of ice to ensure
that they remain fully functional.<
Interior care
Upholstery fabrics/cloth trims/
Alcantara fabrics
Vacuum regularly with a vacuum cleaner to
remove superficial dirt.
To remove severe spots such as stains from
beverages, use a soft sponge or lint-free
microfiber cloth and suitable interior cleaners.
Follow the instructions on the packaging.
Clean the upholstery down to the seams
using a sweeping motion. Avoid strong
rubbing.<
Opened Velcro fasteners on pants or
other articles of clothing can damage the
seat covers. Ensure that Velcro fasteners are
closed.<
Leather/leather trim
The leather used by BMW is a high quality
natural product. Slight irregularities in the
leather are a typical characteristic of natural
leather.<
Dust and road grit in the pores and folds of the
leather have an abrasive effect, leading to
increased wear and causing the leather surface
to become brittle prematurely. Therefore, fre-
quently clean the leather of dust using a cloth or
vacuum cleaner.

Changing wheels
Your BMW comes with run-flat tires as standard
equipment. This eliminates the need to change
a wheel immediately in the event of a puncture.
For information on continuing to drive with a
damaged tire, refer to Indication of a flat tire on
page83.
The symbol identifying run-flat tires is a circle
with the letters RSC on the sidewall, refer to
Run-flat tires, page200.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, no spare wheel is available. Your
BMW center will be glad to advise you. Refer
also to New wheels and tires, page200.
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.
Replacing the battery
Use only vehicle battery types that are
approved by the manufacturer of your
vehicle; otherwise, the vehicle may be damaged
or some functions may become partly or com-
pletely unavailable.<
After replacing the battery, have it paired with
the vehicle at your BMW center so that all con-
venience functions are completely available.

Giving and receiving assistance

Being towed
Make sure that the ignition is switched on,
refer to page55; otherwise, the low-beam
headlamps, tail lamps, turn signal indicators and
windshield wipers may be unavailable. Power
steering assistance is not available when the
engine is not running. Thus, braking and steer-
ing will require increased effort. Active steering
is not active and it will be necessary to turn the
steering wheel further.<
Manual transmission
Gearshift lever in neutral position.
Automatic transmission
Selector lever in position N.
Changing selector lever position, refer to
page58.
Do not exceed a towing speed of 45 mph/
70 km/h and a towing distance of
90 miles/150 km; otherwise, the automatic
transmission may be damaged.<
Sports automatic transmission with
double clutch
Make sure that the parking lock P is not
engaged; otherwise, the rear wheels are
immobilized.
When using the car wash function, refer to
page210, make sure that after approx.
30 minutes, the parking lock P is automatically
engaged and thus immobilizes the rear wheels.
In the event of an electrical malfunction or if the
vehicle must be towed for more than approx.
20 minutes, unlock the parking lock manually,
refer to page63.<
When towing, do not exceed a maximum
speed of 30 mph or 50 km/h and a maxi-
mum distance traveled of 30 miles/50 km; oth-
erwise, the transmission may be damaged.<
BMW recommends transporting the vehicle on
a tow truck with a flatbed or towing with the rear
axle raised.
Towing methods
Do not lift the vehicle by a tow fitting or
body and chassis parts; otherwise, dam-
age may result.<
With a tow bar
The towing vehicle must not be lighter
than the towed vehicle; otherwise, it may
be impossible to maintain control.<
The tow fittings used should be on the same
side on both vehicles. Should it prove impossi-
ble to avoid mounting the tow bar at an angle,
please observe the following:
>Clearance and maneuvering capability will
be sharply limited during cornering.
>The tow bar will generate lateral forces if it is
attached offset.
Attach the tow bar to the tow fittings only,
as attaching it to other parts of the vehicle
could result in damage.<
With a tow rope
When starting off in the towing vehicle, make
sure that the tow rope is taut.
To avoid jerking and the associated
stresses on vehicle components when
towing, always use nylon ropes or nylon straps.
Attach the tow rope to the tow fittings only, as
attaching it to other parts of the vehicle could
result in damage.<
