otherwise, engine damage could result.<
Keep oil, grease, etc. out of reach of chil-
dren and heed warnings on the contain-
ers. Otherwise, you could endanger your
health.<
Oil change
Have the oil changed only by your BMW Sports
Activity Vehicle Center or a workshop that
works according to BMW repair procedures
with correspondingly trained personnel.
Approved engine oils
The quality of the engine oil selected has critical
significance for the operation and service life of
an engine. BMW continuously approves spe-
cific oils after confirming their suitability for use
in its vehicles with extensive testing.
Only use approved BMW High Performance
Synthetic Oil.
If you are unable to obtain BMW High Perfor-
mance Synthetic Oil, you can add small
amounts of another synthetic oil in between oil
changes. Only use oils with the API SH specifi-
cation or higher.
Ask your BMW Sports Activity Vehicle
Center for more details concerning BMW
High Performance Synthetic Oil or other
approved synthetic oils.<
You can also call BMW of North America at
1-800-831-1117 or visit the website
www.bmwusa.com to obtain this information.
BMW engines are designed to operate
without additives, and their use could
even lead to damage in some cases.<
Viscosity classes
Viscosity is the oil flow rating as defined in
SAE classes.
The selection of the correct SAE class depends
on the climate conditions in the area where you
typically drive your BMW.
Approved oils belong to SAE classes
5W-40 and 5W-30.<
These oils can be used for driving in all ambient
temperatures.

Coolant consists of water and coolant additive.
Not all commercially available additives are suit-
able for your BMW. Ask your BMW Sports
Activity Vehicle Center for suitable additives.
Only use suitable additives; otherwise,
engine damage may result. The additives
are harmful to your health, so follow the instruc-
tions on the containers.<
Always observe all applicable environ-
mental laws and regulations when dis-
posing of used coolant additives.<
Checking coolant level

and consult the nearest BMW Sports Activity
Vehicle Center as soon as possible. Severe
engine misfire even for only a short period of
time can seriously damage emission control
components, especially the catalytic converter.
Display of the previously described
malfunction on Canadian models.
When the fuel filler cap is not properly
tightened, the OBD system can detect
the vapor leak and the indicator lamp will light
up. If the filler cap is subsequently tightened,
the indicator lamp should go out within a few
days.<

chure.

Replacing components
108 Please have your BMW Sports Activity
Vehicle Center work on lamps whose
replacement is not described here.<
Light-emitting diodes LEDs
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 are related to ordinary
lasers.
Do not remove the covers, and never
stare into the unfiltered light for several
hours, as irritation of the retina could result.<
Xenon lamps*
The service life of these bulbs is very long and
the probability of failure is very low, provided
that they are not switched on and off an unusual
number of times. If one of these bulbs should
nevertheless fail, it is possible to continue driv-
ing with great caution using the fog lamps, pro-
vided traffic laws in your area do not prohibit
this.
To avoid risk of potentially fatal injuries
due to the extremely high voltages at
which these units operate, service work should
always be entrusted to qualified personnel.<

Inserting compact wheel
The compact wheel is reinserted in the reverse
sequence of its removal.
When attaching the retaining strap to the
compact wheel, make sure the belt is
threaded through 2 rim openings, with one
unoccupied hole between them; otherwise, the
compact wheel could come loose in an acci-
dent.<
Preparing wheel change
1.Observe the safety precautions on
page112.
2.Secure the vehicle to prevent it from rolling:
Place the wheel chock behind the front
wheel on the side of the vehicle opposite
the side being raised. If the vehicle is parked
on a downward slope, place the wheel
chock securely in front of this wheel. If the
road surface is steeply inclined, take addi-
tional preventive steps to stop the vehicle
from rolling.
3.Loosen the wheel lugs by a half turn.
Jacking up vehicle
1.Position the vehicle jack at the jacking point
closest to the wheel so that the entire sur-
face of the jack base perpendicularly con-
tacts the ground under the jacking point.
The vehicle jack is designed for
changing wheels only. Do not attempt
to raise another vehicle model with it or to
raise any load of any kind. To do so could
cause accidents and personal injury.<2.Guide the jack head into the rectangular
recess of the jacking point when cranking
up, refer to drawing inset.
3.Jack the vehicle up until the wheel you are
changing is raised from the ground.
Mounting a wheel
1.Unscrew the lug bolts and remove the
wheel.
2.Remove accumulations of mud or dirt from
the mounting surfaces of the wheel and
hub. Clean the lug bolts.
3.Position the new wheel or compact wheel.
Secure the wheel by screwing at least two
lug bolts into opposite bolt holes. When you
mount wheels other than Genuine BMW
light-alloy wheels, different lug bolts may
also be required.
4.Screw in the remaining lug bolts. Tighten all
the bolts securely in a diagonal pattern.
5.Lower the jack and remove it from beneath
the vehicle.
After mounting
1.Tighten the lug bolts in a diagonal pattern.
To ensure safety, always have the lug
bolts checked with a calibrated
torque wrench as soon as possible to
ensure that they are tightened to the speci-
fied torque. The tightening torque is
101lbft/140Nm.<
2.Stow the defective wheel in the cargo area.
3.Check and correct the tire inflation pressure
at the earliest opportunity.

Replacing components
114 Protect valve stems with valve stem
seal caps from dirt and contamina-
tion. Dirt in valve stems is a frequent source
of gradual air loss.<
4.Reinitialize the Flat Tire Monitor
* or reset
the Tire Pressure Monitor
*, refer to
pages54, 55.
Do not initialize the Flat Tire Monitor
when driving with a compact wheel.<
5.Replace the defective tire as soon as possi-
ble and have the new wheel/tire balanced.
Driving with compact wheel
Drive reservedly and do not exceed a speed of
50 mph/80 km/h.
Mounting the compact wheel can change the
driving characteristics. For example, it can
reduce tracking stability during braking, extend
braking distances, and alter self-steering char-
acteristics in the limit range. With winter tires,
these characteristics are more pronounced.
Only one compact wheel may be
mounted. You should re-equip with
wheels and tires of the original size as soon as
possible.<
