Temperature
The temperature grades are A Ð the 
highest Ð, 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 Vehicle Safety 
Standard No. 109. Grades B and A repre-
sent 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 load-
ing, either separately or in combination, 
can cause heat buildup and possible tire 
failure.< 
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 page 193.
M+S
Winter and all-season tires.
These have better winter properties than 
summer 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. 
Tire tread 
The tread depth should not fall below e in/
3 mm. 
At tread depths below e in/3 mm, there is 
an increased risk of high-speed hydroplan-
ing, even when only small amounts of 
water are present on the road surface.As winter tires display a noticeable loss in 
their ability to cope with cold-weather driv-
ing conditions once the tread wears to 
below k/K in/4 mm, to ensure continued 
safety you should always have such tires 
replaced.
Wear indicators at the tread-groove base, 
refer to arrow, are distributed over the tire's 
circumference and are marked on the side 
of the tire with TWI Ð Tread Wear Indicator. 
These indicators signal at a tread depth 
of k/FK in/1.6 mm that the legally permitted 
wear limit has been reached. 
Tire damage 
Unusual vibrations encountered dur-
ing normal vehicle operation can 
indicate tire failure or some other vehicle 
defect. This can, for example, 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. Should this occur, 
respond by immediately reducing your 
speed. Carefully proceed Ð or have your 
vehicle towed Ð to the nearest BMW center 
or tire dealer to have the wheels or tires 
inspected.
Tire damage, extending to sudden and 
complete loss of pressure in extreme 
cases, can pose a potentially lethal safety 
hazard for the vehicle's occupants and 
other road users alike.<

Storage
Always store wheels and tires in a cool, dry 
place with as little exposure to light as pos-
sible. Always protect tires against all con-
tact with oil, grease and fuels.
Do not exceed the maximum tire inflation 
pressure indicated on the side wall of the 
tire.
Run-flat tires*
You will recognize run-flat tires by a circular 
symbol containing the letters RSC on the 
side of the tire. They consist of self-con-
tained tires and special rims. The tire rein-
forcement ensures that the tire retains 
some residual safety in the event of pres-
sure drop and driving remains possible to 
a restricted degree. 
If you switch from summer to winter 
tires, or vice versa, use run-flat tires, 
as in the event of a breakdown there is no 
spare wheel available. In this case, BMW 
recommends that you consult your BMW 
center. Your BMW center is qualified to 
handle run-flat tires and equipped with the 
necessary special tools.< 
Continuing driving with a damaged 
tire
Driving on run-flat tires can continue, 
depending on the vehicle load and the 
severity of the tire damage, at a maximum 
speed of 50 mph/80 km/h. 
In the case of complete inflation pressure 
loss, 0 psi/kPa, or obvious tire damage, 
you can estimate the possible distance for continued driving on the basis of the fol-
lowing guide values: 
>With low load:
1 to 2 persons without luggage:
Approx. 150 miles/250 km
>With medium load:
2 persons, luggage compartment full, or 
4 persons without luggage:
Approx. 90 miles/150 km
>With full load:
More than 4 persons, luggage compart-
ment full:
Approx. 30 miles/50 km.
Drive reservedly and do not exceed 
a speed of 50 mph/80 km/h. With 
inflation pressure loss, the driving charac-
teristics change, for example reduced track 
stability on braking, extended braking dis-
tance, and altered self-steering character-
istics.< 
Snow chains*
BMW only tests certain snow chains, clas-
sifies them as road-safe and approves 
them. Consult your BMW center for more 
information. BMW recommends only using 
these approved, narrow-link snow chains. 
These snow chains are approved exclu-
sively for use in pairs on the rear wheels, 
and should only be mounted on tires
with the dimensions 245/50 R 18. Observe 
the manufacturer's instructions when 
installing snow chains.Do not exceed a 
vehicle speed of 30 mph/50 km/h with the 
chains mounted.
After mounting snow chains, do not 
activate the Flat Tire Monitor.
When you are driving with snow chains, it 
can be beneficial to switch off DSC briefly, 
refer to page 93.<

Checking oil level
1.Park the vehicle on a level surface 
2.Switch the engine off after it has 
reached normal operating temperature 3.After approx. 5 minutes, pull the dip-
stick out and wipe it off with a clean lint-
free cloth, paper towel, or similar mate-
rial 
4.Carefully push the dipstick all the way 
into the guide tube and pull it out again 
5.The oil should extend to between the 
two marks on the dipstick. 
As is the case with fuel economy, the rate 
at which the engine uses oil is strongly 
influenced by driving style and operating 
conditions.

Antifreeze and anticorrosion agents are 
flammable. Therefore, do not pour over hot 
engine parts, as otherwise they could catch 
fire and cause burns.
Always observe the instructions for use 
provided on the containers.< 
Always observe all applicable rules 
and regulations for environmental 
protection when disposing of used anti-
freeze and anticorrosion agents.< 
Checking coolant level 
Correct coolant level with the engine cold Ð 
approx. +687/206:
1.Turn the cap of the expansion tank 
counterclockwise to allow any accumu-
lated pressure to escape, then continue 
turning to open 
2.The coolant level is correct when the 
coolant extends to between the MIN 
and MAX marks on the filler neck, refer 
to the diagram adjacent to the filler 
neck 
3.If the coolant is low, slowly add coolant 
up to the specified level Ð do not overfill. 
Brake fluid 
The symbol lights up and a mes-
sage appears in the Check Control: 
The brake fluid in the reservoir has 
fallen to below the minimum level. 
The brake fluid reservoir is located under 
the microfilter housing trim panel on the 
driver's side of the vehicle. To have brake 
fluid added to the system, or to have the source of any brake fluid loss traced and 
rectified, please contact your BMW center, 
which can also supply the factory-
approved Ð DOT 4 Ð brake fluids. 
Brake fluid is hygroscopic: it absorbs 
moisture from the atmosphere over 
the course of time.
To ensure that the brake system continues 
to provide safe and reliable performance, 
remember to have the brake fluid changed 
every two years at the latest, refer to 
page 82 and to the Service and Warranty 
Information Booklet for US models or the 
Warranty and Service Guide Booklet for 
Canadian models. 
Brake fluid is toxic and also damages vehi-
cle paintwork. Always store these agents in 
tightly-closed original containers kept well 
away from the reach of children.
Do not spill the fluid and do not refill the 
brake fluid reservoir to beyond the MAX 
mark. Should it come into contact with hot 
engine components, the brake fluid could 
ignite and cause personal injury in the form 
of burns.< 
Always observe all applicable envi-
ronmental rules and regulations when 
disposing of used brake fluid.< 
Warning lamp for Canadian models. 
Brake hydraulic systems 
A low brake-fluid level combined with 
longer-than-usual pedal travel could be 
a sign that one of the brake system's 
hydraulic circuits has failed. 
Proceed to the nearest BMW center. 
Remember that pedal travel may be 
increased, and there may also be a sub-
stantial increase in the amount of pedal 
pressure required to brake the vehicle. 
Please adapt your driving style accord-
ingly.<

Rules and regulations 
California Proposition 65 
Warning 
California laws require us to issue the fol-
lowing warning:
Engine exhaust and a wide variety of 
automobile components and parts, 
including components found in the interior 
furnishings in a vehicle, contain or emit 
chemicals known to the State of California 
to cause cancer and birth defects and 
reproductive harm. In addition, certain flu-
ids contained in vehicles and certain prod-
ucts of component wear contain or emit 
chemicals known to the State of California 
to cause cancer and birth defects or other 
reproductive harm. 
Battery posts, terminals and related acces-
sories contain lead and lead compounds. 
Wash your hands after handling. 
Used engine oil contains chemicals that 
have caused cancer in laboratory animals. 
Always protect your skin by washing thor-
oughly with soap and water.< 
OBD connector 
The Onboard Diagnostic OBD interface 
socket is located on the left of the driver's 
side under the instrument panel and under 
a cover.
The cover has the letters OBD on it.The purpose of the OBD system is to 
ensure proper operation of the emission 
control system for the vehicle's lifetime. 
The system monitors emission-related 
components and systems for deterioration 
and malfunction. 
An indicator lamp informs you of the 
need for service, not of the need to 
stop the vehicle. However, the sys-
tems should be checked by your BMW 
center at the earliest possible opportunity.
Indicator lamp for Canadian mod-
els.
Under certain conditions, the indicator 
lamp will blink or flash. This indicates a 
rather severe level of engine misfire. When 
this occurs, you should reduce speed and 
consult the nearest BMW center as soon as 
possible. Severe engine misfire over only a 
short period of time can seriously damage 
emissions control components, especially 
the catalytic converter. 
When the fuel filler cap is not properly 
tightened, the OBD system can 
detect the vapor leak and the indicator will 
light up. If the filler cap is subsequently 
tightened, the indicator lamp should go out 
within a few days.<

Change the wheel only on a level, firm sur-
face which is not slippery. The vehicle or 
the jack could slip to the side if you attempt 
to raise the vehicle on a soft or slippery sur-
face such as snow, ice, tiles, etc.  
Position the jack on a firm support surface.
Do not use a wooden block or similar 
object as a support base for the jack, as 
this would prevent it from extending to its 
full support height and reduce its load-car-
rying capacity.
To avoid serious or fatal injury: never lie 
under the vehicle, and never start the 
engine while it is supported by the jack.< 
What you will need
