Flat Tire Monitor
The concept
The Flat Tire Monitor keeps track of the
inflation pressures in the four fitted tires as
you drive. The system provides an alert
whenever the inflation pressure drops sig-
nificantly in relation to the pressure another
tire.
The check of the tire inflation pressure is
based on monitoring the relative speeds of
the wheels. A flat tire is detected and
reported on the basis of a deviation in cer-
tain speed ratios.
Functional requirement
So that the Flat Tire Monitor can learn the
correct inflation pressure, please perform
the following:
1.Check the inflation pressures in all tires
2.Compare with the inflation pressure
table on page 87 and correct if neces-
sary
3.Initialize the system.
Limits of the system
The Flat Tire Monitor cannot indicate
sudden severe tire damage caused
by outside factors and does not detect a
natural, even pressure drop in all four
tires.<
In the following situations, on the other
hand, there can be delays in detecting tire
pressure losses, and even system failure:
>When driving on snow-covered or slip-
pery road surfaces
>In the case of performance-oriented
driving: slip on the drive wheels, high
lateral acceleration
>False alarms and undetected loss of
pressure may occur when you are driv-
ing with snow chains fitted>When driving with a compact wheel, the
Flat Tire Monitor cannot operate.
Initializing the system
Perform the initialization immediately
every time you correct the inflation
pressure, change a tire or change a wheel
or all wheels. A drive is required for this
purpose.<
1.Before the start of driving, start the
engine, but do not drive off
2.Press the button until the yellow indica-
tor lamp in the instrument cluster lights
up for a few seconds
3.Drive off.
It takes a few minutes until the Flat Tire
Monitor can detect and indicated a flat tire.
Do not initialize the system when driv-
ing with snow chains or with a com-
pact wheel.<
Flat tire
Indicator lamp
The symbol in the instrument clus-
ter lights up in yellow.
1.Reduce speed and stop the vehicle
carefully. Avoid sudden braking and
steering maneuvers
2.Identify damaged tire
If identification is not possible,
contact your BMW Sports Activity
Vehicle Center.<
3.Replace the damaged tire, refer to
Changing a wheel on page 103.

Technology for comfort, convenience and safety
54
Brake force display
The brake force display indicates the inten-
sity with which you are applying your
brakes to drivers of following vehicles.
The display consists of two stages:
>Normal braking:
Brake lamp 1 lights up on both sides of
the vehicle together with the center
brake lamp
>Heavy braking and braking with ABS:
Brake lamps 1 and 2 light up on both
vehicle sides together with the center
brake lamp.
Airbags
The following airbags are located beneath
the marked covers:
1Front airbags for driver and front pas-
senger
2Head airbags in front and rear
3Side airbags in front and rear
*
Protective effect
The front airbags help protect the driver
and front passenger by responding to fron-
tal impacts in which safety belts alone can-not provide adequate restraint. When
needed, the head and side airbags help
provide protection in the event of side
impact. The relevant side airbag supports
the side upper body area. The relevant
head airbag supports the head and pro-
vides protection against objects entering
the vehicle.
The airbags are deliberately not triggered
in every impact situation, e.g. less severe
accidents, certain roll-over situations or
rear-end collisions.
The rear seat side airbags may
already have been deactivated by a
BMW Sports Activity Vehicle Center.
Labels in the rear door opening should indi-
cate the status of your rear seat side air-
bags. If you are uncertain of their status, or
wish to have the airbags activated or deac-
tivated, please contact your BMW Sports
Activity Vehicle Center.<
For information on the correct sitting posi-
tion, refer to page 27.
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 reten-
tion system from the vehicle. Never modify
or tamper with either the wiring or the indi-
vidual components in the airbag system.
This category includes the upholstery in the
center of the steering wheel, on the instru-
ment cluster, the side trim panels on the
doors, and the roof pillars 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 trig-
gered, because there is a danger of burns.
If you note any indication of system mal-
function, if you desire to have an airbag
deactivated, or if the airbag retention sys-
tem is triggered in response to an accident,
you should always entrust all inspection,
repair and dismantling operations to your
BMW Sports Activity Vehicle Center.
Unprofessional attempts to service the sys-
tem could lead to failure in an emergency
or undesired airbag activation, either of
which could result in personal injury.

Lamps
Parking lamps/low beams
Parking lamps
The front, rear and side vehicle
lighting is switched on. You can use
the parking lamps for parking. For
lighting on one side for parking as an addi-
tional feature, refer to page 58.
Low beams
When you switch on the ignition
with the headlamps on, the head-
lamps go out and only the parking
lamps remain on.
Lamp defective
The indicator lamp lights up:
At least one bulb of the exterior
lighting on the vehicle is defective.
Replacing the bulbs, refer to page 99.
Pathway lighting
When you activate the headlamp flasher
after parking the vehicle and switching off
the lamps, the low beams will come on for
a brief period.
You may also have this function deac-
tivated if you wish.<
Lights on warning
If you turn the ignition key to position 0, an
acoustic signal sounds when you open the
driver's door for a few seconds to remind
you that the light has not yet been switched
off
.
Daytime driving lamps*
You can leave the light switch in the second
position: all external lamps go out when
you switch off the ignition.
Always observe all applicable laws govern-
ing the use of daytime driving lamps.
You can switch on the parking lamps when
needed using the standard procedure
described under Parking lamps.
You can have the daytime driving
lamp circuit activated on your vehi-
cle.<
Automatic headlamp control*
When you set the switch to this
position, the system activates and
switches on and off the low beams
in response to changes in ambient light
conditions, for instance, in tunnels, at dawn
and dusk, and in rain and snow.
Following automatic activation the
vehicle's external lighting remains on
when you switch on the fog lamps.<
Automatic headlamp control cannot
serve as a substitute for the driver's
judgment in determining when the vehicle
lamps should be switched on. For example,
the system cannot detect fog. To avoid
safety risks, you should always switch on
the lamps manually under these condi-
tions.<
You can have the sensitivity of the
headlamp control adjusted.<
Adaptive Head Light*
The concept
Adaptive Head Light is a variable headlamp
control system that enables dynamic illumi-
nation of the road surface. Depending on
the steering angle and other assumptions,
the light from the headlamp follows the
course of the road.

to a fire, and with it the risk of serious prop-
erty damage as well as personal injury.<
Parking the vehicle
Condensation forms in the air conditioner
system during operation, and then exits
under the vehicle. Traces of condensed
water under the vehicle are thus normal.
Before driving into the car wash
Fold in the exterior mirrors, refer to
page 31, as otherwise they could be dam-
aged due to the width of the vehicle.
Deactivate the rain sensor as otherwise
damage could result from undesired wiper
activation, refer to page 42.
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 surface. This phenomenon is referred
to as hydroplaning, and is characterized by
a partial or complete loss of contact
between tires and road surface, ultimately
undermining your ability 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 transmission may be damaged.<
Safe braking
Emergency stops
The best way to brake is to apply maximum
pressure to the brake pedal during emer-
gency Ð panic stops. Since the vehicle
maintains steering responsiveness, you
can nevertheless avoid possible obstacles
with a minimum of steering effort.
Pulsation at the brake pedal combined with
sounds from the hydraulic circuits indicates
to the driver that ABS is in its active mode. Do not drive with your foot resting on
the brake pedal. Otherwise, even light
but consistent pedal pressure can lead to
high temperatures, brake wear and possi-
bly even brake failure.<
Wet conditions
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 gener-
ated by the brake applications helps to dry
the brake pads and rotors. The required
braking force will then be available when
you need it.
On a grade
You can retain full and unimpaired braking
efficiency by downshifting to a gear in
which only minimal brake applications are
needed when descending long or steep
downhill stretches.
You can further enhance the engine's brak-
ing 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
page 38. This strategy helps you avoid
placing excessive loads on the brake sys-
tem.
During slower downhill driving, use the Hill
Descent Control HDC, refer to page 51.
Never drive with the clutch pressed,
with the transmission in Neutral or
with the engine switched off, as otherwise
there is no engine braking when the trans-
mission is in Neutral, and no power-assist
for brakes and steering.
Never allow floor mats, carpets or any other
objects to protrude into the area around the
accelerator and brake pedals and obstruct
their movement.<
Corrosion
When the vehicle is driven only occasion-
ally, during extended periods when the
vehicle is not used at all, and in operating
conditions where brake applications are

Stowing cargo
>Load heavy cargo as far forward and as
low as possible, placing it directly
behind the bulkhead behind the rear
seats
>Cover sharp edges and corners
>Pull out the partition net, refer to
page 72, making sure that objects can-
not penetrate the partition net
>For very heavy cargo when the rear seat
is not occupied, secure each safety belt
in the opposite buckle.
Cargo, securing
>Use the luggage net* to hold down
small and lightweight luggage and
cargo, refer to page 72
>For larger and heavier pieces, load
securing equipment
* is available from
your BMW Sports Activity Vehicle Cen-
ter. Lashing eyes for attaching these
heavy-duty straps have been provided
in your vehicle's luggage compartment,
refer to page 73
>Read and comply with the information
enclosed with the load-securing
devices.Always position and secure the load
correctly. If you do not, it can even
endanger the passengers during braking or
evasive maneuvers.
Never exceed either the approved gross
vehicle weight or either of the approved
axle loads, refer to page 116, as excessive
loads can pose a safety hazard, and may
also place you in violation of freeway safety
laws.
You should never transport heavy or hard
objects unsecured in the passenger com-
partment, as they could fly around and
pose a safety hazard to the vehicle's occu-
pants even during abrupt braking or eva-
sive maneuvers .<
Roof-mounted luggage
rack*
Because roof racks raise the vehicle's cen-
ter of gravity when loaded, they have a
major effect on its handling and steering
response.
You should therefore always remember not
to exceed the approved roof weight, the
approved gross vehicle weight or the axle
loads when loading the rack.
You can find the specified weights in the
Technical data section on page 116.
Make sure that the load is not too heavy,
and that it does not extend outward to
beyond the limits of the loading surface.
Always load the heaviest pieces first Ð on
the bottom. Be sure that adequate clear-
ance is maintained for raising the glass
roof, and that objects do not project into
the opening path of the tailgate.
Secure roof-mounted cargo correctly and
securely to prevent it from shifting or being
lost during the trip.
Drive smoothly. Avoid sudden acceleration
and braking maneuvers. Take corners gen-
tly.

Do not fill beyond the upper mark on the
dipstick. Excess oil can damage the
engine.
Adding engine oil
While you should wait until the level has
dropped to just above the lower mark
before adding oil, you should never allow
the oil level to fall below this mark.
BMW engines are designed to oper-
ate without additives, and their use
could even lead to damage in some cases.
This also applies to the manual transmis-
sion, automatic transmission, the differen-
tial and the power steering system.<
Recommendation: have the oil change
conducted by your BMW Sports Activity
Vehicle Center.
Continuous exposure to used oil has
caused cancer in laboratory testing.
For this reason, any skin areas that come
into contact with oil should be thoroughly
washed with soap and water.
Always store oils, grease and similar mate-
rials so that they are inaccessible to chil-
dren. Comply with warning labels and
information on containers.<
Always observe all applicable rules
and regulations for environmental
protection when disposing of used oil.<
Approved engine oils
The quality of the engine oil selected has
critical significance for the operation and
service life of an engine. Based on exten-
sive testing, BMW has approved only cer-
tain engine oils.
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 Sports Activity Vehicle
Center for details concerning the spe-
cific BMW High Performance 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.
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
Indicator lamp
The indicator lamp lights up:
Coolant level is too low; top up at
the earliest opportunity.
Do not add coolant to the cooling sys-
tem when the engine is hot. Escaping
coolant can cause burns.
Antifreeze and anticorrosion agents are
hazardous to health. You should always
store them in their original containers and
in a location which is inaccessible to chil-
dren. Antifreeze and anticorrosion agents
are flammable. Therefore, do not pour over
hot engine parts, as otherwise they could
catch fire and cause burns. Always observe
the instructions for use provided on the
containers.<

Light-emitting diodes LEDs
Light-emitting diodes installed behind
translucent lenses serve as the light source
for many of the controls and displays in
your vehicle. These light-emitting diodes,
which operate using a concept similar to
that applied in conventional lasers, are offi-
cially designated as Class 1 light-emitting
diodes.
Do not remove the covers, and never
stare into the unfiltered light for sev-
eral hours, as irritation of the retina could
result.<
Changing a wheel
Safety precautions to observe in the
event of a flat tire and during all tire
changes:
Park the vehicle as far as possible from
passing traffic. Park on a firm, flat, surface.
Switch on the hazard warning flashers.
Lock the steering wheel in straight-ahead
setting of the wheels. Set the handbrake
and engage first gear, reverse gear or
selector-lever position P.
All passengers should be outside the vehi-
cle and well away from your immediate
working area, behind a guardrail, for
instance.
If a warning triangle or portable hazard
warning lamp is required, set it up on the
roadside at an appropriate distance from
the rear of the vehicle. Comply with all safety guidelines and regulations.
Change the wheel only on a level, firm sur-
face which is not slippery. The vehicle or
the jack could slip to the side if you attempt
to raise the vehicle on a soft or slippery sur-
face such as snow, ice, tiles, etc.
Position the jack on a firm support surface.
Do not use a wooden block or similar
object as a support base for the jack, as
this would prevent it from extending to its
full support height and reduce its load-car-
rying capacity.
To avoid serious or fatal injury: never lie
under the vehicle, and never start the
engine while it is supported by the jack.<
What you will need
Open tailgate and raise or remove floor
cover, refer to page 72.

Mounting compact 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 turning at
least two lug bolts into opposite bolt
holes
4.Screw in the remaining lug bolts.
Tighten all the bolts securely in a diag-
onal pattern
5.Lower the jack and remove it from
beneath the vehicle
6.Tighten the lug bolts in a diagonal pat-
tern
7.Check and correct the tire inflation
pressure at the earliest opportunity.
Protect valve stems and valve stem
seal caps against dirt and contamina-
tion. Dirt in valve stems is a frequent source
of gradual air loss.<
After mounting the compact wheel or cor-
recting the inflation pressure, reinitialize
the Flat Tire Monitor, refer to page 53.
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.
To ensure safety, always have the lug bolts
checked with a calibrated torque wrench to
ensure that they are tightened to the spec-
ified torque of 101 lb ft/140 Nm as soon as
possible.<
Stow the defective wheel in the luggage
compartment.
When you mount wheels other than Genu-
ine BMW light-alloy wheels, different lug
bolts may also be required.
Replace the defective tire as soon as pos-
sible and have the new wheel/tire bal-
anced.
Driving with the compact wheel
Drive reservedly and do not exceed a
speed of 50 mph/80 km/h. Do not
deactivate DSC, as otherwise unstable
driving conditions may result.<
The driving characteristics change, for
example reduced track stability on braking,
extended braking distance, and altered
self-steering characteristics in the limit
range. In conjunction with winter tires,
these characteristics are more pro-
nounced.
Only one compact wheel may be
mounted. You should re-equipping to
wheels and tires of the original size as
quickly as possible.<
Battery
Battery care
The battery is 100% maintenance-free, i.e.,
the electrolyte will last for the life of the bat-
tery when the vehicle is operated in a tem-
perate climate.
Please contact your BMW Sports
Activity Vehicle Center with any ques-
tions concerning the battery.<
Do not disconnect the battery when
the engine is running. If you do so, the
ensuing voltage surge will damage the
vehicle's onboard electronics.<
Indicator lamp
The battery charge-current indica-
tor lamp lights up:
The battery is no longer being
charged. There is a defect on the alternator
V-belt or charge current circuit of the alter-
nator. Contact the nearest BMW Sports
Activity Vehicle Center.
Do not continue driving if the V-belt is
defective. The engine could be dam-
aged due to overheating.
Moreover, an increased amount of force is
required for steering if the onboard supply
voltage falls dramatically.<
