Drive-off assistant
The drive-off assistant enables you to start off
conveniently on slopes. The parking brake is
not required for this purpose.1.Hold the vehicle with the brake pedal.
2.Release the brake pedal and immediately
drive off quickly.
The drive-off assistant holds the vehicle
for approx. 2 seconds after releasing the
brake pedal. Depending on the load, the vehicle
may also roll back slightly during this time.
After releasing the brake pedal, immediately
start quickly, otherwise the drive-off assistant
no longer holds the vehicle after approx.
2 seconds and it begins to roll back.<
Self-leveling suspension*
The concept
The self-leveling suspension on the rear axle
assures a continuous ground clearance.
To do so, the height of the vehicle is measured
by sensors at both rear wheels.
If the actual height deviates from the defined
height, e.g. due to loading of the vehicle, then
this difference is compensated for very quickly.
In addition, spring motions resulting from cor-
nering or irregularities in the road surface are
reduced to a minimum.
The system functions automatically.
Malfunctions
Malfunctions are displayed via Check Control,
refer to page82.
FTM Flat Tire Monitor*
The concept
The system does not measure the actual infla-
tion pressure in the tires.
The system detects a pressure loss in a tire by
comparing the rotational speeds of the individ-
ual wheels while moving.
In the event of a pressure loss, the diameter and
therefore the rotational speed of the corre-
sponding wheel change. This is detected and
reported as a flat tire.

Technology for comfort, convenience and safety

Function requirements
The system must have been initialized while the
tire inflation pressure was correct; otherwise,
reliable signaling of a flat tire is not ensured.
Initialize the system after every correction of the
tire inflation pressure and after every tire or
wheel change.
System limits
Sudden serious tire damage caused by
external influences cannot be indicated in
advance.<
A natural, even pressure loss in all four tires
cannot be detected. Therefore, check the tire
inflation pressure regularly.
In the following situations, 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.

Initialization
The initialization process adopts the set infla-
tion tire pressures as reference values for the
detection of a flat tire. Initialization is started by
confirming the inflation pressures.
Do not initialize the system when driving with
snow chains
* or with the compact wheel*.

tinued automatically.<
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 a major loss in tire
inflation pressure.
Actions in the event of a flat tire
Run-flat tires
You can continue driving with a damaged tire at
speeds up to 50 mph/80 km/h.
If the vehicle is not equipped with run-flat
tires as provided at the factory, refer to
page249, do not continue driving. Continuing
to drive with a flat tire could cause severe acci-
dents.<

A loss of tire inflation pressure results in a
change in the handling characteristics, e.g.
reduced lane stability during braking, a longer
braking distance and altered self-steering prop-
erties.<
Vibrations or loud noises while driving can
indicate complete failure of the tire.
Reduce your speed and stop; otherwise, pieces
of the tire could come loose and cause an acci-
dent. Do not continue driving, and contact your

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 pressure label. (If your vehi-
cle has tires of a different size than the size indi-
cated on the vehicle placard or tire inflation
pressure label, you should determine the
proper tire inflation pressure for those tires.)
As an added safety feature, your vehicle has
been equipped with a tire pressure monitoring
system (TPMS) that illuminates a low tire pres-
sure telltale when one or more of your tires is
significantly underinflated. Accordingly, when
the low tire pressure telltale illuminates, you
should stop and check your tires as soon as

Technology for comfort, convenience and safety
104 possible, and inflate them to the proper pres-
sure. Driving on a significantly underinflated tire
causes the tire to overheat 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 TPMS 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. This sequence will con-
tinue upon subsequent vehicle startups as long
as the malfunction exists. When the malfunc-
tion indicator is illuminated, the system may not
be able to detect or signal low tire pressure 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.
Lane departure warning*
The concept
On roads with lane markings, this system warns
you at speeds exceeding approx. 40 mph/
65 km/h when the vehicle is about to leave the
lane.
The steering wheel begins vibrating lightly.
The system does not issue a warning if the turn
signal is set before leaving the lane.
Switching on/off
Press button 1 on the steering wheel.
>On: lane markings 2 light up.
>Off: lane markings 2 go out.
The system can issue warnings at speeds
exceeding approx. 40 mph/65 km/h.
The state is stored for the remote control cur-
rently in use.
Display
1The system is activated.
2Arrows: at least one lane marking was
detected and warnings can be issued.
Issuing a warning
If the vehicle begins leaving the lane and a lane
marking has been detected, the steering wheel
begins vibrating.
If the turn signal is set before the lane is
changed, a warning is not issued.
Canceling a warning
The warning is canceled:
>Automatically after approx. 3 seconds.
>After the vehicle returns to its lane.
>During heavy brake application.

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 rear axle differential
Always obey all official speed limits.
Up to 1,200 miles/2,000 km
Drive at various engine and vehicle speeds, but
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 kickdown 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 not achieve their full trac-
tion potential until after 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 increases 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*/
panoramic glass sunroof*
An open glass sunroof/panoramic glass sunroof
or open windows likewise increase the drag
coefficient and therefore the fuel consumption.
Checking tire inflation 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 and 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 vehicle remains stationary.
Instead, begin to drive at a moderate engine

Things to remember when driving
140 planing, and is characterized by a partial or
complete loss of contact between the tires and
the road surface, ultimately 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 page248.
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 pressure 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 braking 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 transmission, if necessary into
first gear, refer to page64. 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 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 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 respond 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.
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 blowout.<

Tire inflation pressure
Information for your safety
The condition of the tires and the maintenance
of the specified tire pressure 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 depressurized, i.e. flat
tires, except run-flat tires. A flat tire will seri-
ously impair your vehicle's handling and braking
response. Attempts to drive 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
page100, or reset the Tire Pressure Monitor,
refer to page102.<
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 Activ-
ity Vehicle Center. tion pressure for your tires, observe the follow-
ing:

Tire inflation pressures for speeds
up to 100 mph/160 km/h
For normal driving up to 100 mph/160 km/h,
adjust pressures to the respective 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.<
Tire inflation pressures for speeds
