48 perature display. In addition, an acoustic
signal sounds and the display flashes for a
short time.
After an ice warning has been issued,
the display returns to the previous
setting. You can have this activated/deacti-
vated.<
Please bear in mind that the ice warn-
ing does nothing to alter the fact that
glare ice may be present on roads at tem-
peratures higher than +37.57/+36, for
instance, on bridges and shaded roads.<
Clock
12 or 24 hour mode
If your vehicle is equipped with a computer,
you can have the time displayed in the 12
or 24 hour mode.
During the display, hold down the com-
puter button in the turn indicator lever until
the display changes.
Average fuel consumption
If you press the button in the turn signal
indicator lever for a longer period, the cur-
rently displayed average value for fuel con-
sumption is recalculated from that moment
onwards.
Cruising range
The cruising range is determined on the
basis of the past driving style and the
present volume of fuel.
Always refuel as soon as possible
once your cruising range falls to
below 30 miles/50 kilometers, as other-
wise engine functions are not ensured and
damage can occur.<
Average speed
If you press the button in the turn signal
indicator lever for a longer period, the cur-
rently displayed average value for speed is
recalculated from that moment onwards.

Never attempt to continue driving
until the tank is completely empty, as
engine functions could be affected, and the
vehicle could sustain damage as a result.<
Fuel specifications
The engine uses lead-free gasoline only.
Required fuel:
Premium Unleaded Gasoline,
minimum 91 AKI
AKI = Anti Knock Index.
Do not use leaded fuels. The use of
leaded fuels will cause permanent
damage to the system's oxygen sensor and
the catalytic converter.<

Wheels and tires
90 with specialized knowledge and corre-
sponding equipment.<
The correct wheel and tire combination
affects various systems whose function
would otherwise be impaired, e.g. ABS,
DSC or xDrive.
Have the wheel and tire assemblies bal-
anced every time either a wheel or a tire is
replaced.
BMW does not recommend the use of
retreaded tires, as otherwise driving
safety may be reduced. Possible variations
in the design and the age Ð which could be
substantial Ð of the carcasses can lead to
unusually rapid wear.<
The right wheels and tires
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 manufacturing tolerances mean that
even wheels and tires with identical official
size ratings could actually have different
dimensions than the approved units Ð these
differences could lead to body contact, and
with it the risk of severe accidents. If non-
approved wheels and tires are used, BMW
cannot evaluate their suitability, and there-
fore cannot be held liable for driving
safety.<
To maintain good handling and vehicle
response, use only tires of a single tread
configuration 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 pos-
sible.
Recommended tire brands
BMW tests certain tire brands for each tire
size, classifies them as road-safe and
approves them. You can obtain a list of
these from your BMW Sports Activity Vehi-
cle Center. Observe any country-specific
regulations, e.g. on making a correspond-
ing entry in the vehicle documents.
The factory-mounted tires have been spe-
cially selected to provide optimized perfor-mance when installed on your vehicle; if
properly cared for, they will provide a com-
bination of safety and excellent ride com-
fort.
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.
When switching to winter tires, observe the
descriptions at Tire condition and Replac-
ing wheels/tires, refer to page 89.
Observing speed ratings
Never exceed the maximum speed for
which the winter tires are rated.
Unprofessional attempts by laymen to ser-
vice tires can lead to damage and acci-
dents. Have this work performed by skilled
professionals only. The technicians at your
BMW Sports Activity Vehicle Center will be
glad to assist you with the required profes-
sional knowledge and specialized equip-
ment.<
Storage
Store wheels or tires in a cool, dry place,
protecting them against light whenever
possible. Protect the tires against contact
with oil, grease and fuel.
Do not exceed the maximum tire inflation
pressure specified on the side of the tire.
Snow chains*
Do not exceed a vehicle speed of
30 mph/50 km/h with snow chains
mounted.<
Only certain snow chains have been tested
by BMW and classified and approved as
safe. You can obtain a list of these from
your BMW Sports Activity Vehicle Center.
BMW recommends the use of approved
narrow-link snow chains only. These snow
chains are approved exclusively for use on

Washer fluid
Windshield and headlamp washer
system
Antifreeze agent for the washer sys-
tems is inflammable. For this reason,
keep it away from sources of flame and
store it only in its original containers. Store
it so that it is inaccessible to children.
Always observe the instructions for use
provided on the containers.<
We recommend that you mix the
washer ßuid before adding it to the
reservoir.<
Capacity:
approx. 6.9 US quarts/6.5 liters.
Fill with water and, if required, with an anti-
freeze additive according to manufac-
turer's recommendations.
Engine oil
Indicator lamp
Engine oil pressure
The indicator lamp lights up red:
Stop the vehicle immediately and
switch off the engine. Check the
engine oil level; top up as required. If the oil
level is correct: contact the nearest BMW
Sports Activity Vehicle Center.
Do not continue driving. The engine
could be damaged because of inade-
quate lubrication.<
Engine oil level
The indicator lamp lights up yellow
while driving:
The oil level is at the absolute mini-
mum. Add engine oil as soon as possible.
Until then, do not drive more than
approx. 30 miles/50 km.
The indicator lamp lights up yellow
after the engine is switched off:
Top up engine oil at the earliest
opportunity Ð when refueling.
Engine oil sensor
The indicator lamp lights up yellow
within 20 seconds after starting the
engine:
The oil level sensor is defective. Please
have it checked by a BMW Sports Activity
Vehicle Center.
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. 1.1 US quarts/1 liter.

Laws and regulations
California Proposition 65
Warning
California laws require us to state 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 accessories contain lead and
lead compounds. Wash your hands after
handling. Used engine oil contains chemi-
cals that have caused cancer in laboratory
animals. Always protect your skin by wash-
ing thoroughly with soap and water.<
OBD connector
The interface socket for the Onboard Diag-
nostic is located on the left of the driver's
side at the bottom of the instrument cluster
and under a cover. The cover has the let-
ters OBD on it.
The most important components for the
composition of the emissions can be
checked by a device across this interface. If the Service Engine Soon indicator
lamp comes on either continuously
or intermittently, this indicates a
fault in the emissions-related electronic
systems. Although the vehicle remains
operational, you should have the systems
checked by your BMW Sports Activity
Vehicle Center at the earliest possible
opportunity.
The illuminated indicator lamp informs you
of the need for service, not that you need to
stop the vehicle. However, the systems
should be checked by your BMW Sports
Activity Vehicle Center at the next opportu-
nity.
If the indicator lamp blinks or flashes, this
indicates a high level of engine misfire.
Reduce speed and contact the nearest
BMW Sports Activity Vehicle Center imme-
diately. Severe engine misfiring over even a
short period of time can seriously damage
emission control system components,
especially the catalytic converter.
Service Engine Soon indicator lamp
for Canadian models.
If the fuel filler cap is not on tight
enough, the OBD system can detect
leaking vapor and the indicator lamp will
light up. If the fuel filler cap is then tight-
ened, the indicator lamp will usually go out
after a short period of time.<
