Self-leveling suspension*
Malfunction
The warning lamp for self-leveling
suspension lights up yellow and a
message is shown on the Control
Display. A malfunction has occurred in the self-
leveling suspension. Stop and check the vehi-
cle. If it is considerably lower at the rear than at
the front, and possibly also on one side – rear
left compared to rear right –, proceed to the
nearest BMW Sports Activi ty Vehicle Center or
a workshop that works according to BMW
repair procedures with correspondingly trained
personnel. Drive with a ppropriate caution in the
meantime. The vehicle has reduced ground
clearance and driving co mfort may be notice-
ably reduced. Even if th e orientation of the vehi-
cle is normal, when a malfunction is indicated
on the display, you should proceed to the near-
est BMW Sports Activity Vehicle Center or a
workshop that works according to BMW guide-
lines and uses appropriately trained personnel.
FTM Flat Tire Monitor*
The concept
The Flat Tire Monitor detects a pressure loss in
one tire by comparing the speeds of the individ-
ual wheels during driving.
In the event of a pressure loss, there is a change
in the rolling circumference and therefore the
rotation speed of the corresponding wheel. The
system detects this change and reports it as a
flat tire.
Function requirements
In order to assure the re liable reporting of a flat
tire, the system must be initialized for the cor-
rect tire inflation pressure. The initialization must be repeated after
each time the tire inflation pressure is cor-
rected and after every tire or wheel change. <
System limits
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 situatio ns, the system could be
delayed or malfunction:
> System has not been initialized
> Driving on snowy or slippery road surface
> Sporty driving style: slip in the drive wheels,
high lateral acceleration
> Driving with snow chains
*
When you are driving with the compact wheel*
the Flat Tire Monitor is unable to function.
Initializing system
The initialization finishes during driving,
which can be interrupted at any time.
When driving resumes, th e initialization is con-
tinued automatically. Do not initialize the sys-
tem when driving with snow chains
* or with the
compact wheel
*. <

Indication of a flat tire
The warning lamp lights up red. A
message appears on the Control Dis-
play. In addition, an acoustic signal
sounds. There is a flat tire or extensive inflation
pressure loss.
If you have deactivated DS C, it will be activated
automatically.
1. Cautiously reduce speed to below 50 mph/
80 km/h. Avoid sudden braking and steer-
ing maneuvers. Do not exceed a speed of
50 mph/80 km/h.
In case of further air loss of the defective
wheel, its position will be indicated to you
on the Control Display.
If the vehicle is not equipped with run-
flat tires as provided at the factory, refer to page
256, do not continue driving.
Continuing to drive with a flat tire could
cause severe accidents. <
2. At the next opportunity, check the air pres-
sure in all four tires.
If the tire inflation pressure in all four
tires is correct, the Flat Tire Monitor
may not have been initialized. The system
must then be initialized. <
3. In the event of complete tire pressure loss,
0 psi/0 kPa, you can estimate the possible
distance for continued driving on the basis
of the following guide values:
> With a light load:
1 to 2 persons without luggage:
approx. 155 miles/250 km
> With a medium load:
2 persons, cargo bay full, or
4 persons without luggage:
approx. 95 miles/150 km
> With a full load:
4 or more persons, cargo bay full:
approx. 30 miles/50 km
Drive cautiously and do not exceed
speeds of 50 mph/80 km/h or else you
run the risk of causing an accident. In the event
of pressure loss, vehicl e handling changes. This
includes reduced tracking stability in braking,
extended braking distance and altered natural
steering characteristics.
If unusual vibrations or loud noises occur while
the vehicle is being driven , this can indicate final
failure of the damaged tire. Reduce speed and
stop at a suitable location as soon as possible,
otherwise pieces of the tire could become
detached and cause an accident. Do not con-
tinue driving, but instead contact the BMW
Sports Activity Vehicle Center. <
TPM Tire Pressure Monitor*
The concept
TPM checks the tire inflation pressure in the
four mounted tires. The system reports when

the tire inflation pressu
re has dropped consid-
erably in one or several tires.
Function requirements
In order to assure the re liable reporting of a flat
tire, the system must have been reset with the
correct tire inflation pressure.
Always use wheels with TPM electronics, oth-
erwise fault-free operation of the system is not
ensured.
Reset the system again after each correc-
tion of the tire inflation pressure and after
every tire or wheel change.<
System limits
TPM cannot announce sudden serious
tire damage caused by external influ-
ences. <
The system does not function properly if it has

The system is inactive and cannot display a flat
tire if a wheel has be en mounted without TPM
electronics, e.g. a compact wheel
*, or if TPM is
temporarily interfered wi th by other systems or
devices which use the same radio frequency.
Status display on Control Display
The tire and system stat us is indicated by the
color of the tires.
TPM takes the fact that the tire pressure
changes during driving in to account. A correc-
tion is only required if requested by TPM with
the color.

Explanation according to the NHTSA/
FMVSS 138 Tire Pressure Monitoring
Systems
Each tire, including the spare (if provided),
should be checked monthly when cold and
inflated to the inflation pressure recommended
by the vehicle manufacturer on the vehicle plac-
ard or tire inflation pressu re label. (If your vehi-
cle has tires of a different size than the size indi-
cated on the vehicle plac ard or tire inflation
pressure label, you should determine the
proper tire inflation pr essure for those tires.)
As an added safety feature, your vehicle has
been equipped with a tire pressure monitoring
system (TPMS) that illumi nates a low tire pres-
sure telltale when one or more of your tires is
significantly underinflate d. Accordingly, when
the low tire pressure telltale illuminates, you
should stop and check your tires as soon as
possible, and inflate them to the proper pres-
sure. Driving on a significantly underinflated tire
causes the tire to overhe at and can lead to tire
failure. Underinflation also reduces fuel effi-
ciency and tire tread life, and may affect the
vehicle's handling and stopping ability.
Please note that the TP MS is not a substitute
for proper tire maintenance, and it is the driver's
responsibility to maintain correct tire pressure,
even if underinflation has not reached the level
to trigger illumination of the TPMS low tire
pressure telltale.
Your vehicle has also been equipped with a
TPMS malfunction indicator to indicate when
the system is not operating properly. The
TPMS malfunction indicator is combined with
the low tire pressure telltale. When the system
detects a malfunction, the telltale will flash for
approximately one minute and then remain con-
tinuously illuminated. Th is sequence will con-
tinue upon subsequent vehicle start-ups as
long as the malfunction exists. When the mal- function indicator is illuminated, the system
may not be able to detect or signal low tire pres-
sure as intended. TPMS malfunctions may
occur for a variety of reasons, including the
installation of replacement or alternate tires or
wheels on the vehicle that prevent the TPMS
from functioning properly. Always check the
TPMS malfunction telltale after replacing one or
more tires or wheels on your vehicle to ensure
that the replacement or alternate tires and
wheels allow the TPMS to
continue to function
properly.
Active steering*
The concept
The active steering active ly varies the steering
angle of the front wheels in relation to the steer-
ing wheel movements. In addition, it also varies
the steering force required for steering depend-
ing on the vehicle's speed.
When you are driving in the low road speed
range, e.g. in a town or when parking, the steer-
ing angle increases, i.e. the steering becomes
very direct. In the higher speed range, on the
other hand, the steering angle is reduced more
and more. This improves the handling capability
of your BMW over the entire speed range.
In critical situations, the system can make tar-
geted corrections to th e steering angle pro-
vided by the driver and thus stabilize the vehicle
before the driver intervenes.
Malfunction
The warning lamp lights up yellow
and a message is shown on the Con-
trol Display. The active steering is
defective or has been temporarily
deactivated. At low speeds, greater steering
wheel movements are required, whereas at
higher speeds, the vehicle reacts more sensi-
tively to steering wheel movements. The stabil-
ity-promoting intervention can also be deacti-
vated. Proceed cautiously and drive
defensively. If active st eering is defective, have
the system checked.

Things to remember when driving
138
Things to remember when driving
Break-in period
Moving parts need breaking-in time to adjust to
each other. To ensure that your vehicle contin-
ues to provide optimized economy of operation
throughout an extended service life, we request
that you devote careful attention to the follow-
ing section.
Engine and differential
Always obey all official speed limits.
Up to 1,200 miles/2,000 km
Drive at changing engine and vehicle speeds,
however do not exceed:
> Gasoline engine
4,500 rpm or 100 mph/160 km/h
> Diesel engine
3,500 rpm or 90 mph/150 km/h
Avoid full-throttle operation and use of the
transmission's kick-down mode during these
initial miles.
From 1,200 miles/2,000 km
The engine and vehicle speed can gradually be
increased.
Tires
Due to technical factors associated with their
manufacture, tires do no t achieve their full trac-
tion potential until afte r an initial break-in
period. Therefore, drive reservedly during the
first 200 miles/300 km.
Brake system
Brakes require an initial break-in period of
approx. 300 miles/500 km to achieve optimized
contact and wear patterns between brake pads
and rotors. Drive in a reserved manner during
this break-in period.
Following part replacement
Observe the break-in instructions again if com-
ponents mentioned above must be replaced
after subsequent driving operation.
Saving fuel
The fuel consumption of your vehicle depends
on various factors. Through a few simple steps,
your driving style, and regular maintenance, you
can have a positive influence on your fuel con-
sumption and environmental impact.
Removing unnecessary cargo
Additional weight incr eases fuel consumption.
Removing add-on parts after use
Remove unneeded auxiliary mirrors, roof or rear
luggage racks after use. Add-on parts attached
to the vehicle impede the aerodynamics and
increase the fuel consumption.
Closing windows and glass sunroof*/
panorama glass sunroof*
An open glass sunroof/panorama glass sunroof
or open windows likewise increase the drag
coefficient and therefore the fuel consumption.
Checking tire in flation pressures
regularly
Check and correct the tire inflation pressure as
needed at least twice a month and before long
trips.
An insufficient tire inflation pressure increases
the rolling resistance an d thus increases the
fuel consumption and tire wear.
Driving off immediately
Do not allow the engine to warm up by leaving it
running while the vehicl e remains stationary.
Instead, begin to drive at a moderate engine

planing, and is characterized by a partial or
complete loss of contac
t between the tires and
the road surface, ultima tely undermining your
ability to steer and brake the vehicle. <
The risk of hydroplaning increases as the tread
depth of the tires decreases, also refer to Mini-
mum tread depth on page 255.
Driving through water
Maximum water depth:
>BMW X5 20 in/50 cm
> BMW X6 17 in/45 cm
Only drive through water up to the above-
mentioned depth at no greater than walk-
ing speed; otherwise, the engine, electrical sys-
tem, and transmission can be damaged. <
Braking safely
Your BMW is equipped with ABS as a standard
feature. In situations that require it, it is best to
brake with full force. Since the vehicle maintains
steering responsiveness, you can still avoid
possible obstacles with a minimum of steering
effort.
Pulsation of the brake pedal, combined with
sounds from the hydraulic circuits, indicate that
ABS is in its active mode.
Do not drive with your foot resting on the
brake pedal. Even light but consistent
pedal pressure can lead to high temperatures,
brake wear and possibly even brake failure.<
Driving in wet conditions
When roads are wet or there is heavy rain,
briefly exert gentle pre ssure on the brake pedal
every few miles. Monitor traffic conditions to
ensure that this maneuver does not endanger
other road users. The heat generated in this
process helps dry the pads and rotors to ensure
that full braking efficiency will then be available
when you need it.
Hills
To prevent overheating and the resulting
reduced efficiency of the brake system,
drive long or steep downhill gradients in the gear in which the least br
aking is required. Even
light but consistent pressure on the brake pedal
can lead to high temperatures, brake wear and
possibly even brake failure. <
The braking effect of the engine can be further
increased by downshifting in the manual mode
of the automatic transmis sion, if necessary into
first gear, refer to page 71. This prevents an
excessive strain on the brakes.
Do not drive in idle or with the engine
stopped, otherwise there will be no
engine braking action or support of the braking
force and steering.
Never allow floor mats, carpets or any other
objects to protrude into the area of movement
of the pedals and impair their operation. <
Corrosion on brake rotors
When the vehicle is driven only occasionally,
during extended periods when the vehicle is not
used at all, and in op erating conditions where
brake applications are less frequent, there is an
increased tendency for corrosion to form on
rotors, while contaminan ts accumulate on the
brake pads. This occurs because the minimum
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 re spond with a pulsating
effect that even extended application will fail to
cure.
When vehicle is parked
Condensation forms in the automatic climate
control system during operation, and then exits
under the vehicle. Traces of condensed water
under the vehicle are therefore normal.
Before driving into a car wash
Fold in the exterior mirrors, refer to page 57,
otherwise they could be damaged due to the
width of the vehicle.
Release the parking brake, particularly when
you have activated Auto matic Hold, refer to
page 67.

Tire inflation pressure
Information for your safety
The condition of the tires and the maintenance
of the specified tire pres sure are crucial not only
to the tire's service life, but also to driving com-
fort and most importantly, driving safety.
Checking pressure
Only check tire inflation pressure when the tires
are cold. This means 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 as needed, even on the
compact tire
*: at least twice a month and before
starting long trips. If you fail to observe this pre-
caution, you may be driving on tires with incor-
rect 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 acci-
dent. Do not drive with de pressurized, i.e. flat
tires, except run-flat tires. A flat tire will seri-
ously impair your vehicle's handling and braking
response. Attempts to dr ive on a flat tire can
lead to a loss of control over the vehicle. <
After correcting the tire inflation pressure,
reinitialize the Flat Tire Monitor, refer to
page 100, or reset the Tire Pressure Monitor,
refer to page 102.<
Pressure specifications
The tables below provide all the correct inflation
pressures for the specified tire sizes at ambient
temperature.
The inflation pressures apply to the
tire sizes and tire brands respectively
approved and recommended by BMW; a list
of these is available from your BMW Sports
Activity Vehicle Center. <
For correct identification of the right tire infla-
tion pressure for your tires, observe the follow-
ing:
> Tire sizes of your vehicle
> Load conditions
> Maximum allowable driving speed
Tire inflation pre ssures for speeds
up to 100 mph/160 km/h
For normal driving up to 100 mph/160 km/h,
adjust pressures to the re spective tire inflation
pressures listed on the following pages in the
column Traveling speeds up to max. of
100 mph/160 km/h to achieve optimum driving
comfort.
These pressure specifications can be found on
the door post when you open the driver's door.
The permissible top speed for these tire
inflation pressures is 100 mph/160 km/h.
Do not exceed this speed, otherwise tire dam-
age and accidents may result. <
