Refueling
Fuel filler door
Always switch off the engine before refu-
eling, as it is not possible to add fuel with
the engine running, and attempts to do so may
also trigger the Service Engine Soon lamp.<
To open and close: press the rear edge of the
fuel filler door.
Manual release
In the event of an electrical malfunction in the
system, you can release the fuel filler door man-
ually:
1.Open the cover flap in the cargo area on the
right-hand side panel, refer to page68.
2.Pull the green button.
Always observe all applicable precautions
and regulations when handling fuels.
Never carry spare fuel containers in your vehi-
cle. Whether empty or full, these containers can
leak, cause an explosion, and lead to fire in the
event of a collision.<
Observe the following when refueling
When handling fuels, comply with all of
the applicable safety precautions posted
at the service station.<
Put the filler cap in the bracket attached to the
fuel filler door.
When refueling, insert the filler nozzle com-
pletely into the filler pipe. Lifting the filler nozzle
during refueling
>results in premature pump shutoff
>can lead to reduced efficiency in the fuel-
vapor recovery system
The fuel tank is full when the filler nozzle clicks
off the first time.
Closing fuel filler cap
Fit the cap and turn it clockwise until you clearly
hear a click.
Close the filler cap carefully after refueling
until a click is heard. While closing, be
sure not to squeeze the strap which is fastened
to the cap. A loose or missing cap will activate
the Check gas cap lamp
*.<
The warning lamp
* lights up.
The fuel filler cap is not properly closed
or is missing. Check whether the fuel
filler cap is properly closed.
Fuel tank capacity
Approx. 17.7 gallons/67 liters, including the
reserve capacity of approx. 2 gallons/8 liters.

Tire inflation pressure
Information for your safety
It is not merely the tire's service life, but also
driving comfort and – to a great extent – driving
safety that depend on the condition of the tires
and the maintenance of the specified tire pres-
sure.
Checking pressure
Only check tire inflation pressure when the tires
are cold, i.e. after a maximum of 1.25 miles/2 km
driving or when the vehicle has been parked for
at least 2 hours. When tires are warm, the tire
inflation pressure increases.
Check the tire inflation pressure regularly
and correct it if necessary, including com-
pact wheel: at least every two weeks and before
beginning a longer trip. If you fail to observe this
precaution you may be driving on tires with
incorrect tire pressures, a condition that can not
only compromise your vehicle's driving stability,
but also lead to tire damage and the risk of an
accident. Do not drive with a depressurized, i.e.
flat tire. A flat tire will seriously impair your vehi-
cle's handling and braking response. Attempts
to drive on a flat tire can lead to loss of control
over the vehicle.<
After correcting the inflation pressure(s),
always reinitialize the Flat Tire Monitor,
refer to page50.<
Inflation pressures for factory-installed
tires
The inflation pressures for your factory-
installed tires can be found on the door jamb
when you open the driver's door.
Inflation pressures for other tire sizes
The table below provides all the correct inflation
pressures for the specified tire sizes at ambient
temperature.
For correct identification of the right tire
inflation pressure for your tires, observe
the specifications for the corresponding tire
sizes.<
Tire size
The inflation pressures apply to the tire sizes
approved and tire brands recommended by
BMW; a list of these is available from your
BMW Sports Activity Vehicle Center.

Tire identification marks
Knowledge of the labeling on the side of the tire
makes it easier to identify and choose the right
tires.
Tire size
Speed code letter
Q = up to 105 mph/160 km/h
T = up to 118 mph/190 km/h
H = up to 131 mph/210 km/h
V = up to 150 mph/240 km/h
W = up to 167 mph/270 km/h
Y = up to 186 mph/300 km/h
Tire Identification Number
Tires with DOT codes meet the guidelines of
the U.S. Department of Transport.
DOT code:
Tire age
The tire's date of manufacture is indicated on
the sidewall:
DOT ... 3004 indicates that a tire was manufac-
tured in week 30 of the year 2004.BMW recommends that you replace all tires
after 6 years at most, even if some tires may last
for 10 years.
Uniform Tire Quality Grading
Quality grades can be found where applicable
on the tire sidewall between tread shoulder and
maximum section width.
For example:
Tread wear 200 Traction AA
Temperature A
DOT Quality Grades
Tread wear
Traction AA A B C
Temperature A B C
All passenger car tires must conform to
Federal Safety Requirements in addition
to these grades.<
Tread wear
The tread wear grade is a comparative rating
based on the wear rate of the tire when tested
under controlled conditions on a specified gov-
ernment test course.
For example, a tire graded 150 would wear one
and one-half, 1γ, times as well on the govern-
ment course as a tire graded 100. The relative
performance of tires depends upon the actual
conditions of their use, however, and may
depart significantly from the norm due to varia-
tions in driving habits, service practices and dif-
ferences in road characteristics and climate.
Traction
The traction grades, from highest to lowest, are
AA, A, B, and C.
Those grades represent the tire's ability to stop
on wet pavement as measured under controlled
conditions on specified government test sur-
faces of asphalt and concrete. A tire marked C
may have poor traction performance.
The traction grade assigned to this tire is
based on straight-ahead braking traction
tests, and does not include acceleration, cor-
nering, hydroplaning, or peak traction charac-
teristics.< e.g. 235/50 R 18 97 V

New wheels and tires
Have new wheels and tires installed only
by your BMW Sports Activity Vehicle
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 danger of subsequent dam-
age and related safety hazards.<
Retreaded tires
BMW does not recommend the use of
retreaded tires, as otherwise driving
safety may be reduced. The causes for this
include the possibly different tire casing struc-
tures and the often wide variations in their age,
which can result in a limited service life.<
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 manufac-
turing tolerances mean that even wheels and
tires with identical official size ratings could
actually have different dimensions than the
approved units – these differences could lead to
body contact, and with it the risk of severe acci-
dents. If non-approved wheels and tires are
used, BMW cannot evaluate their suitability,
and therefore cannot be held liable for driving
safety.<
You can ask your BMW Sports Activity Vehicle
Center for the correct wheel-and-tire combina-
tion.
The correct wheel-and-tire combination affects
various systems whose function would other-
wise be impaired, e.g. ABS, DSC or xDrive.
To maintain good handling and vehicle
response, use only tires of a single tread config-
uration 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 possible.
Recommended tire sizes and brands
BMW tests certain tire brands for each tire size,
classifies them as road-safe and approves
them. These are available at a specialized
dealer, preferably your BMW Sports Activity
Vehicle Center. Observe any country-specific
regulations, e.g. on making a corresponding
entry in the vehicle documents.
The factory-mounted tires have been specially
selected to provide optimized performance
when installed on your vehicle; if properly cared
for, they will provide a combination of safety and
excellent ride comfort.
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.
Observing speed ratings
Never exceed the maximum speed for
which the winter tires are rated. Unpro-
fessional attempts by laymen to service tires
can lead to damage and accidents. Have this
work performed by skilled professionals only.
The technicians at your BMW Sports Activity
V e h i c l e C e n t e r w i l l b e g l a d t o a s s i s t y o u w i t h t h e
required professional knowledge and special-
ized equipment.<
Storage
Store wheels or tires in a cool, dry place, pro-
tecting them against light whenever possible.
Protect the tires against contact with oil, grease
and fuel. Do not exceed the maximum tire infla-
tion pressure indicated on the side wall of the
tire.

Under the hood
88
Under the hood
Never attempt to perform any service or
repair operations on your vehicle without
the required professional technical training. If
you are not familiar with the regulations to be
observed, have work on your vehicle carried out
only by a BMW Sports Activity Vehicle Center
or a workshop that uses personnel trained in
accordance with BMW requirements. If this
work is not carried out properly, there is a dan-
ger of subsequent damage and related safety
hazards.<
Hood
Unlocking
Pull the lever located under the left side of the
instrument cluster.
Opening
Press the release handle and open the hood.
Closing
Let the hood fall from approx. 1 ft/30 cm so that
you hear it engage.
Observe the same precautions that apply
to all closing operations by ensuring that
the hood's travel range is clear and unob-
structed before allowing the hood to fall into
position.
If you see any signs that the hood is not com-
pletely closed while driving your vehicle, you
should stop at once and close it securely.<

Do not fill beyond the upper mark on the
dipstick. Excess oil can damage the
engine.<
Adding engine oil
Do not add oil until the oil level has dropped to
just above the lower marking on the dipstick,
refer to page90.
Add oil within the next 30 miles/50 km,
otherwise engine damage could result.<
Store oil, grease etc., well out of the reach
of children; always observe all warning
labels on the containers.<
Oil change
Have oil changed only at your BMW Sports
Activity Vehicle Center or at 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. Based on extensive testing, BMW
has approved only certain engine oils.
Use only 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 between oil
changes. Use only oils with the API SH specifi-
cation or higher.
Ask your BMW Sports Activity Vehicle
Center for details concerning the specific
BMW High Performance Synthetic Oil or syn-
thetic oils which have been approved. 1-800-831-1117 or visit this 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 ratings
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 are in SAE classes 5W-40
and 5W-30.<
These oils may be used for driving in all ambient
temperatures.
Coolant
Warning lamp
The warning lamp lights up: coolant
level is too low; top off at the next
opportunity.
Do not open the cooling system when the
engine is hot. Escaping coolant can cause
burns.<
Coolant consists of water and coolant additive.
Not all commercially available additives are suit-
able for your BMW. Ask your BMW Sport Activ-
ity Vehicle Center for suitable additives.
Only use suitable additives, as otherwise
engine damage may result. The additives
present a health hazard.<
Always observe all applicable environ-
mental laws and regulations when dis-
posing of used coolant additives.<
Checking coolant level
1.The engine must be at ambient tempera-
ture.
2.Turn the cap of the expansion tank counter-
clockwise to allow any accumulated pres-

Maintenance
The BMW maintenance
system
The BMW maintenance system supports the
preservation of the traffic and operating safety
of your BMW.
Regular maintenance is not only required for
the safety of the vehicle, it also improves the
resale value.
Service Interval Display
The BMW maintenance system takes the driv-
ing conditions of the vehicle into account when
determining service intervals:
From the point of view of maintenance,
62,000 miles/100,000 km accumulated in
short-distance urban driving are not the equiva-
lent of the same distance covered at moderate
speeds in long-distance highway travel.
The BMW maintenance system is divided into
engine oil service as well as Inspections I and II.
Determining the maintenance intervals accord-
ing to the actual loads on the vehicle covers
every kind of operating situation. However,
even those who drive only short distances,
significantly less than 6,200 miles/10,000 km
annually, should have the engine oil changed at
least every 2 years since oil deteriorates over
time, regardless of use.
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 perfor-
mance, remember to have the brake fluid changed at least every two years by a BMW
Sports Activity Vehicle Center, also refer to the
Service and Warranty Information Booklet for
US models or the Warranty and Service Guide
Booklet for Canadian models.<
Service and Warranty Information

Service Guide Booklet for Canadian
models
For detailed information on required mainte-
nance items and the work involved, please refer
to the Service and Warranty Information Book-
let for US models or to the Warranty and Service
Guide Booklet for Canadian models.
Depending on operating conditions, it may be
advisable to have the body checked for damage
from rocks or gravel as a precaution against cor-
rosion.
BMW recommends that you have your
BMW Sports Activity Vehicle Center per-
form the maintenance and repair.
Check that the maintenance work is recorded in
the Service and Warranty Information Booklet
for US models or the Warranty and Service
Guide Booklet for Canadian models. These
entries will serve as proof that the vehicle has
received regular maintenance.<
OBD connector
The interface socket for the Onboard Diagnos-
tics is located on the left of the driver's side at

94 the bottom of the instrument cluster and under
a cover. The cover has the letters OBD on it.
The most important components for the com-
position of the emissions can be checked by a
device via this interface.
If the Service Engine Soon indicator
lamp lights up either continuously or
intermittently, this indicates a malfunc-
tion in the emissions-related electronic sys-
tems. Although the vehicle remains operational,
you should have the systems checked by your
BMW Sports Activity Vehicle Center at the ear-
liest possible opportunity.
The illuminated indicator 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 opportunity.
If the indicator blinks or flashes, this indicates
a high level of engine misfire. Reduce speed
and contact the nearest BMW Sports Activity
Vehicle Center immediately. Severe engine
misfiring over even a short period of time can
seriously damage emission control system
components, especially the catalytic converter.

malfunction on 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 tightened, the indicator lamp
will usually go out after a short period of time.<
Event Data Recorders
Your vehicle may be equipped with one or more
sensing and diagnostic modules or a recording
device capable of recording or transmitting cer-
tain vehicle data or information. In addition, if
you have a Subscription Service Agreement for
