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 con-
trolled conditions on a specified indoor lab-
oratory 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.<
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 page192.
M+S
Winter and all-season tires.
These have better winter properties than
summer tires.
Tire condition
Inspect your tires frequently for treadwear,
signs of damage and for foreign objects
lodged in the tread. Check the tread depth.
Tire tread
The tread depth should not drop below
εin/3 mm, although, for example, Euro-
pean legislation only specifies a minimum
tread depth of κ/ΦΚin/1.6 mm. At tread
depths below εin/3 mm, there is an
increased risk of high-speed hydroplaning, 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 κ/Κin/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 – Tread Wear Indicator.
These indicators signal at a tread depth of
κ/ΦΚin/1.6 mm that the legally permitted
wear limit has been reached.
Wheel/tire damage
Due to low-profile tires, please note
that wheels, tires and suspension
parts are more susceptible to road hazard
and consequential damages.
Unusual vibrations encountered during
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.
In these cases reduce speed immediately.
Drive carefully to the next BMW center or
tire dealer, or have the vehicle towed to one
of these locations if necessary.
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.<

Engine oil
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.
The oil quantity between the two marks
of the dipstick is approx. 1.65 US quarts/

Under the hood
196 1.5 liter. Do not fill beyond the upper mark
on the dipstick. Excess oil can damage the
engine.
Adding engine oil
Wait until the level has dropped to just
above the lower mark or a message
appears in the Check Control before add-
ing oil.
Store oil, grease etc., well out of the
reach of children; always observe all
warning labels on the containers.<
Specified engine oils
The quality of the engine oil selected has
critical significance for the operation and
service life of an engine. BMW approves
only specific oils after confirming their suit-
ability for use in its vehicles with extensive
testing.
Use only approved BMW High Perfor-
mance Synthetic Oil.
If you are unable to obtain BMW High Per-
formance Synthetic Oil, you can add small
amounts of another synthetic oil between
oil changes. Use only oils with the API SH
specification or higher.
Ask your BMW center for details con-
cerning the specific BMW High Per-
formance Synthetic Oil or synthetic oils
which have been approved.<
You can also call BMW of North America
at 1-800-831-1117 or visit this website:
www.bmwusa.com to obtain this informa-
tion.
BMW engines are designed to oper-
ate without additives, and their use
could even lead to damage in some
cases.<
Viscosity ratings
Viscosity is the oil flow rating as defined in
SAE classes.
The selection of the correct SAE class
depends on the climatic conditions in the
area where you typically drive your BMW.
Approved oils are in SAE classes
5W-40 and 5W-30.<
These oils may be used for driving in all
ambient temperatures.
Coolant
Do not add coolant to the cooling sys-
tem when the engine is hot. Escaping
coolant can cause burns.<
Coolant consists of water and the addition
of antifreeze and anticorrosion agent. Not
all commercially available additives are
suitable for your BMW. Ask your BMW cen-
ter for suitable additives.
Only use suitable additives, as other-
wise engine damage may result. The
additives present a health hazard; observe
the instructions 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
1.The engine must be at ambient temper-
ature
2.Turn the cap of the expansion tank
counterclockwise to allow any accumu-
lated pressure to escape, then continue
turning to open
3.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

4.If the coolant is low, slowly add coolant
up to the specified level – do not overfill.
5.Twist closed the cap and tighten firmly
6.Have the reason for the coolant loss
eliminated as soon as possible.

Warning lamp on Canadian models.
During continued driving increased
brake pedal travel may be necessary,
and considerably longer braking distances
may result. Please adapt your driving style
accordingly.<
Brake pads
For messages and indicator lamps in the
Info Display, refer to page83.
For your own safety: use only brake
pads that BMW has released for your
particular vehicle model. As BMW cannot
assess the suitability of other brake pads
for use on your vehicle, we are unable to assume continued responsibility for the
vehicle's operating safety if non-approved
pads are installed.<

pressure at the earliest opportunity
Protect valve stems and valve
stem seal caps against dirt and
contamination. Dirt in valve stems is a
frequent source of gradual air loss.<
4.Reinitialize the Flat Tire Monitor, refer
to page 96
5.Replace the damaged tire with a new
one as soon as possible and have the
new wheel balanced.
Driving with spare tire
On certain wheel-tire combinations,
the size of the spare tire deviates from
that of the rest of the tires. The spare tire is
fully capable of running in all load and
speed ranges. However, to recreate the
original conditions, the tire should be
replaced as soon as possible.<
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. The vehicle is equipped
with a Flat Tire Monitor which indicates
punctures.
The reinforcement on the flanks of the
tires means that it is usually not pos-
sible to detect an air loss from outside.<
Flat tire
If you have a flat tire, the indicator lamp
symbol in the Check Control will light up in
red, and a message will appear. In addition,
a gong sounds.
You can find more detailed information on
the Flat Tire Monitor on page96.
Reduce vehicle speed carefully to under
50 mph/80 km/h, avoiding hard brake
applications and steering maneuvers.
If the defective wheel is not recognizable as
such immediately, check the inflation pres-
sure in all four tires.
For reasons of safety, do not arrange
for run-flat tires to be repaired. Your
BMW center has the information needed
for working with these tires and is 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. You can deter-
mine the possible mileage for continued
driving on the basis of the following general
indications:
>Tire inflation pressure 0 psi/kPa:
With empty vehicle approx. 90 miles/
150 km
With full payload approx. 30 miles/
50 km
>Tire inflation pressure 7 psi/50 kPa to
15 psi/100 kPa:
Approx. 300 miles/500 km
>Tire inflation pressure greater than
15 psi/100 kPa:
Approx. 600 miles/1,000 km.
Drive reservedly and do not exceed a
speed of 50 mph/80 km/h. In the case
of air loss, you can expect changes in vehi-
cle handling such as reduce lane stability,
longer braking distances, and changes in
self-steering properties.<
