in the tank.
Fuel tank capacity:
Approx. 17.7 gallons/67 liters.
If the tilt of the vehicle varies, when you are driv-
ing in mountainous areas, for example, the indi-
cator may fluctuate slightly.
Refuel well before the tank is empty, as
otherwise engine functions will not be
ensured and damage can occur if you drive
down to the last drop.<
When you switch on the ignition, the indicator
lamp comes on briefly to confirm that the sys-
tem is operational.

Malfunction
The indicator lamp in the button flashes and a
short continuous tone sounds. PDC is malfunc-
tioning. Switch off PDC. Have the system
checked.
To prevent this problem, keep the sensors
clean and free of ice or snow in order to ensure
that they will continue to operate effectively.
System limits
Even with PDC, final responsibility for
estimating the distance between the
vehicle and any obstructions always remains
with the driver. Even when sensors are involved,
there is a blind spot in which objects cannot be
detected. The system is also subject to the
physical limits that apply to all forms of ultra-
sonic measurement, such as those encoun-
tered with tow bars and trailer couplings, or thin
and wedge-shaped objects etc. Low objects
already displayed, e.g. a curb, can also disap-
pear from the detection area of the sensors
again before a continuous tone sounds.
Loud sources of sound, inside and outside the
vehicle, could drown out the PDC signal tone.<
Keep the sensors clean and free of ice or
snow in order to ensure that they will con-
tinue to operate effectively.
Do not apply high pressure spray to the sensors
for a prolonged period of time. Keep the spray at
least 4 in/10 cm away from the sensors.<
Driving stability control
systems
Your BMW is equipped with an extended array
of systems designed to enhance and maintain
vehicle stability under extreme conditions.
ABS Antilock Brake System
ABS prevents the wheels from locking during
braking. Safe steering response is maintained
even during full braking. This results in an
increase in the active safety.
ABS is operational every time you start the
engine. Safe braking, refer to page73.
EBV Electronic brake-force
distribution
EBV controls the brake system's application
pressure in the rear wheels to ensure stable
deceleration.
DBC Dynamic Brake Control
When the brake pedal is depressed quickly, this
system automatically generates a maximal
braking force distribution and thus helps keep
the braking distance to a minimum during full
braking. This system exploits all of the benefits
provided by ABS.
Do not reduce the pressure on the brake pedal
for the duration of the brake application. DBC is
deactivated when you release the brake pedal.
DSC Dynamic Stability Control
DSC prevents slip at the drive wheels when
starting off and accelerating. DSC also detects
unstable driving conditions, such as a fishtailing
of the vehicle's rear end or the sliding of the
vehicle on its front wheels. In these circum-
stances, DSC helps keep the vehicle on a safe
path, within physical limits, by reducing engine
output and by applying the brakes in individual
wheels.
The DSC is operational every time you start the
engine.
The laws of physics cannot be repealed,
even with DSC. An appropriate driving
style always remains the responsibility of the
driver. Therefore, do not reduce the additional
safety margin again by taking risks.<
Indicator lamp
The indicator lamp goes out shortly
after the engine starts.
When the indicator lamp flashes:
DSC is controlling the drive and braking forces.
When the indicator lamp stays lit:
DSC has been switched off with the button.

Activating system
Press the button; the indicator lamp comes on.
The indicator lamp flashes when the brakes are
applied automatically.
Deactivating system
Press the button again; the indicator lamp goes
out.
HDC is deactivated immediately above approx.
35 mph/60 km/h and after approx. 10 seconds
when the ignition is switched off.
Using HDC
In vehicles with manual transmission:
Use HDC in first gear and in reverse gear, as in
the higher gears the engine's braking action
diminishes.
On vehicles with automatic transmission:
You can use HDC in every drive position.
Malfunction
If the indicator lamp in the button goes out in the
HDC mode or fails to light up when the button is
pressed:
HDC is temporarily not available, as the brake
temperature is too high.
Malfunction in vehicle stability control
systems
The warning lamp lights up yellow.
DBC Dynamic Brake Control is defec-
tive. Have the system checked as soon
as possible.
Display of the previously described
malfunction on Canadian models.If one of the malfunctions described
below occurs, proceed cautiously and
defensively. When driving on poor roads, avoid
using the full throttle or kick-down positions of
the accelerator as well as heavy and panic brak-
ing. Otherwise the drive train may be damaged
or accidents can occur.<
The red brake warning lamp lights up
together with the warning lamps for
ABS and DSC/xDrive. In addition, a
warning signal sounds. ABS, DSC,
HDC and xDrive have failed. Drive may
then only be carried out via the rear
axle. If the brake warning lamp lights up
yellow in the described combination,
the EBV Electronic brake-force distribution is
still available. Have the system checked as soon
as possible.
Display of the previously described
malfunction on Canadian models.
The warning lamp lights up continu-
ously and a warning signal sounds:
DSC or the xDrive all-wheel system has
failed.
The stabilizing interventions of DSC or the all-
wheel drive system xDrive are no longer avail-
able. It is then possible to exert driving force
only via the rear axle. Have the system checked
as soon as possible.
Flat Tire Monitor
The concept
The Flat Tire Monitor keeps track of the infla-
tion pressures in the four mounted tires as you
drive. The system provides an alert whenever
the inflation pressure drops significantly in rela-
tion to the pressure in another tire.

Airbags
The following airbags are located beneath the
marked covers:
1Front airbags for driver and front passenger
2Head airbags in front and rear
3Side airbags in front and rear
*
Protective action
To ensure that the safety systems con-
tinue to provide optimal protection,
please follow the instructions on page24.<
The front airbags help protect the driver and
front passenger by responding to frontal
impacts in which safety belts alone cannot pro-
vide adequate restraint. When needed, the
head and side airbags help provide protection in
the event of side impact. The relevant side air-bag supports the side upper body area. The
respective head air bag supports the head.
The airbags are deliberately not triggered in
every impact situation, e.g. less severe acci-
dents, certain roll-over situations or rear-end
collisions.
Labels in the rear door opening should
indicate the status of your rear seat side
airbags. If you are uncertain of their status, or
wish to have the airbags activated or deacti-
vated, please contact your BMW Sports Activity
Vehicle Center.<
For information on the correct sitting position,
refer to page24.
Do not apply adhesive materials to the
cover panels of the airbags, cover them or
modify them in any other way.
Do not attempt to remove the airbag retention
system from the vehicle. Never modify or
tamper with either the wiring or the individual
components in the airbag system. This cate-
gory includes the upholstery in the center of the
steering wheel, on the instrument cluster, the
side trim panels on the doors, and the roof pil-
lars along with the sides of the headliner. Do not
attempt to remove or dismantle the steering
wheel.
Do not touch the individual components
directly after the system has been triggered,
because there is a danger of burns. When there
are malfunctions, when deactivating, or after
the triggering of the airbag restraint system,
have the testing, repair, removal, and disposal
of the airbag generators executed only by your
BMW Sports Activity Vehicle Center or at a
workshop that works according to BMW repair
procedures with correspondingly trained per-
sonnel and has the required explosives
licenses. Unprofessional attempts to service
the system could lead to failure in an emer-
gency or undesired airbag activation, either of
which could result in personal injury.<
Airbag warning information is also provided on
the sun visors.

Things to remember when driving

Things to remember when driving
Breaking-in
Moving parts should be allowed to adjust to one
another. To ensure that your vehicle provides
maximum economy throughout a long service
life, we request that you observe the following
instructions.
Engine and differential
Up to 1,200 miles/2,000 km:
Drive at varying engine and driving speeds,
however do not exceed 4,500 rpm or 100 mph/
160 km/h in the process:
Always obey all official speed limits.
Refrain from using full throttle and avoid press-
ing the accelerator beyond the kick-down point.
Once you have driven 1,200 miles/2,000 km,
the engine and vehicle speeds can be gradually
increased.
Tires
Due to technical factors associated with their
manufacture, tires do not achieve their full trac-
tion potential until after an initial break-in
period. For this reason, drive with extra care
during the initial 200 miles/300 km.
Obey your local and state maximum speed lim-
its.
When the vehicle is operated on wet or
slushy roads, a wedge of water may form
between the tire and the road surface. This phe-
nomenon is referred to as hydroplaning and can
lead to partial or complete loss of traction, vehi-
cle control and braking effectiveness. Reduce
your speed on wet roads.<
Brake system
Approx. 300 miles/500 km must elapse before
the brake pads and rotors achieve the optimal
pad-surface and wear patterns required for
trouble-free operation and long service life later
on. To break in the separate handbrake drums,
apply the handbrake lightly when coasting to a
stop – at a traffic signal, for instance; use cau-
tion to avoid posing a danger to other road
users.
To avoid corrosion, repeat this procedure from
time to time.
The brake lamps do not come on when the
handbrake is applied.
Vacuum for the brake system servo unit
on your BMW is available only when the
engine is running. When you move the vehicle
with the engine off – e.g. by towing – substan-
tially higher levels of pedal force will be required
to brake the vehicle.<
Clutch
The functio n of the clutch is als o only at its o pti-
mized level after a distance driven of approx.
300 miles/500 km. During this break-in period,
engage the clutch gently.
Following component replacements
Observe the break-in instructions again if previ-
ously addressed components must be replaced
again during driving later.
General driving notes
Closing tailgate
Operate the vehicle only when the tail-
gate is completely closed, as otherwise
exhaust fumes could enter the interior of the
vehicle.<
If special circumstances should make it abso-
lutely necessary to operate the vehicle with the
tailgate open:
1.Close all windows and the panorama glass
sunroof.
2.Greatly increase the air supply of the air
conditioner or automatic climate control,
refer to page56 or59.

Hot exhaust system
As in all vehicles equipped with a catalytic
converter, extremely high temperatures
are generated in this vehicle. Do not remove the
heat shields installed adjacent to various sec-
tions of the exhaust system, and never apply
undercoating to them. When driving, standing
at idle and while parking take care to avoid pos-
sible contact between the hot exhaust system
and any highly flammable materials such as hay,
leaves, grass, etc. Such contact could lead to
a fire, resulting in serious personal injury and
property damage.<
Mobile communications devices in
vehicle
BMW does not recommend using mobile
communications devices, e.g. portable
phones, in the interior of the vehicle without a
direct connection to an outside antenna. Other-
wise the vehicle electronics and mobile com-
munications device can affect each other. In
addition, there is no assurance that the radia-
tion which results during transmission will be
dissipated from the vehicle interior.<
Inside rearview mirror, automatically
dimming*

The inside rearview mirror contains two photo-
cells that control the automatic dimming func-
tion. One is integrated into the mirror glass, the
other is located on the back of the mirror.
For trouble-free operation, keep the photocells
clean and do not cover the area between the
interior rearview mirror and the windshield. Do
not attach any kind of stickers on the windshield
in front of the mirror, either.
When the vehicle is parked
Condensation forms in the air conditioner sys-
tem during operation, and then exits under the
vehicle. Traces of condensed water under the
vehicle are thus normal.
Before driving into a car wash
Fold in the exterior mirrors, refer to page28, as
otherwise they could be damaged due to the
width of the vehicle.
Deactivate the rain sensor as otherwise dam-
age could result from undesired wiper activa-
tion, refer to page39.
Hydroplaning
When driving on wet or slushy roads,
reduce road speed. If you do not, a wedge
of water can form between tires and road sur-
face. This phenomenon is referred to as hydro-
planing, and is characterized by a partial or
complete loss of contact between tires and
road surface, ultimately undermining your abil-
ity to steer and brake the vehicle.<
Driving through water
Do not drive through water on the road if it
is deeper than 20 in/50 cm, and then only
at walking speed. Otherwise, the vehicle's
engine, the electrical systems and the trans-
mission may be damaged.<
Use handbrake on inclines
Do not hold the vehicle in place on slopes
by slipping or riding the clutch, use the
handbrake instead. Otherwise greater clutch
wear will result.<
Safe braking
Your BMW is equipped with ABS as standard
equipment. The best way to brake is to apply
maximum pressure to the brake pedal during
emergency: panic braking. Since the vehicle
maintains steering responsiveness, you can
nevertheless avoid possible obstacles with a
minimum of steering effort.

Things to remember when driving
74 Pulsation at the brake pedal combined with
sounds from the hydraulic circuits indicates to
the driver that ABS is in its active mode.
Wet roads
While driving in wet conditions and in heavy
rain, it is a good idea to apply light pressure to
the brake pedal every few miles. Watch traffic
conditions to ensure that this maneuver does
not endanger other road users. The heat which
is generated by the brake applications helps to
dry the brake pads and rotors. The full braking
force will then be available when you need it.
Hills
To prevent overheating and reduced effi-
ciency of the brake system, drive long or
steep downhill gradients in the gear in which
the least braking is required. Otherwise, even
light but consistent pedal pressure can lead to
high temperatures, brake wear and possibly
even brake failure.<
You can further enhance the engine's braking
effect by selecting a lower gear in the automatic
transmission's manual mode, downshifting as
far as first gear on extremely steep stretches,
refer to page37. This strategy helps you avoid
placing excessive loads on the brake system.
During slower downhill driving, use the HDC Hill
Descent Control, refer to page48.
Never drive with the clutch engaged, the
transmission in Neutral or with the engine
switched off, as otherwise there is no engine
braking when the transmission is in neutral, and
no power-assist for brakes and steering with
the engine switched off.
Never allow floor mats, carpets or other objects
to protrude into the area around the brake or
accelerator pedals and obstruct their move-
ment.<
Corrosion on brake rotors
When the vehicle is driven only occasionally,
during extended periods when the vehicle is not
used at all, and in operating conditions where
brake applications are less frequent, there is an
increased tendency for corrosion to form on
rotors, while contaminants accumulate on the
brake pads. This occurs because the minimal
pressure which must be exerted by the pads
during brake applications to clean the rotors is
not reached.
Should corrosion form on the brake rotors, the
brakes will tend to respond with a pulsating
effect that even extended application will fail to
cure.
Cargo loading
To avoid loading the tires beyond their
approved carrying capacity, never over-
load the vehicle. Overloading can lead to over-
heating and increases the rate at which damage
develops inside the tires. The ultimate result
can assume the form of a sudden air loss.<
Determining load limit
1.Locate the following statement on your
vehicle's placard
*:
The combined weight of occupants
and cargo should never exceed
XXX Ibs. or YYY kg, as otherwise the vehicle
may be damaged and unstable driving con-
ditions may result.<
2.Determine the combined weight of the
driver and passengers that will be riding in
your vehicle.

Wheels and tires
86
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.

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.

Washer fluid
Headlamp* and windshield washer
system
The antifreeze for the washer systems is
flammable. For this reason, keep it away
from sources of flame and store it only in its
original containers. Store it so that it is inacces-
sible to children. Always observe the instruc-
tions for use provided on the containers.<
We recommend that you mix the washer
fluid before adding it to the reservoir.<
Capacity of the windshield washer system:
approx. 3.2 US quarts/3 liters.
Capacity for equipment with headlamp washer
system: approx. 6.9 US quarts/6.5 liters.
Fill with water and, if required, with an antifreeze
additive according to manufacturer's recom-
mendations.

tunity, e.g. when refueling.
Engine oil sensor
The warning lamp lights up yellow
within 20 seconds after starting the
engine:
The oil level sensor is defective. Have checked
as soon as possible.
Checking oil level
1.With the engine at operating temperature,
i.e. after at least 6 miles/10 km of uninter-
rupted driving, park the vehicle in a horizon-
tal position.
2.Switch off engine.
3.After approx. 5 minutes, pull the dipstick out
and wipe it off with a clean lint-free. cloth,
paper towel, or similar material.
4.Carefully push the dipstick all the way into
the guide tube and pull it out again.
The oil should extend to between the two
marks on the dipstick.
5.Push the oil dipstick into the dipstick tube
as far as possible again.
The oil quantity between the two marks of the
dipstick is approx. 1.1 US quarts/1 liter.
