Cleaning rear view camera
The lens of the rear view camera is located on
the liftgate.
The picture quality of the rear view camera may
be impaired by dirt. Clean the lens with a moist,
nonabrasive cloth.
The lens is automatically heated in case of frost.
Driving stability control
systems
Your BMW is equipped wi th an extended array
of systems designed to enhance and maintain
vehicle stability under extreme conditions.
ABS Antilock Brake System
ABS prevents locking of the wheels during
braking. Safe steering response is maintained
even during full braking. Active safety is thus
increased.
ABS is operational every time you start the
engine. Braking safely, refer to page 140.
CBC Cornering Brake Control
When braking during curves or when braking
during a lane change, dr iving stability and steer-
ing response are improved further.
Electronic brake-force distribution
The system controls the brake pressure in the
rear wheels to ensure st able braking behavior.
Brake assistant
When you apply the brakes rapidly, this system
automatically produces the maximum braking
force boost and thus helps to achieve the short- est possible braking distance during full brak-
ing. This system exploits all of the benefits pro-
vided by ABS.
Do not reduce th
e pressure on the brake pedal
for the duration of the full braking.
DSC Dynamic Stability Control
DSC prevents traction lo ss in the driving wheels
when starting off and accelerating. The system
also identifies unstable driving conditions, such
as a loss of traction at the rear of the vehicle or
sliding of the vehicle in its front wheels. In these
cases, DSC helps the vehicle maintain a safe
course within physical lim its by reducing engine
output and through braking actions in the indi-
vidual wheels.
The laws of physics cannot be repealed,
even with DSC. An appropriate driving
style remains the responsibility of the driver.
Therefore, do not restrict the additional safety
margin with a risky driving style, as otherwise
there is a risk of an accident. <
Deactivating DSC
Press the button until the DSC indicator lamp in
the instrument panel lights up, but not longer
than approx. 10 seconds. DTC Dynamic Trac-
tion Control and DSC ar e deactivated together.
Stabilizing intervention s are now not carried
out.
A message appears on the Control Display.
Please note any supplementary information
that appears there.
To increase vehicle stability, activate DSC again
as soon as possible.

play
> Wet road surface and unfavorable lighting
conditions
If the image is distorted, have the basic setting
checked at a BMW Sports Activity Vehicle Cen-
ter.
Special windshield
The windshield is part of the system. The shape
of the windshield complies with the require-
ments of the Head-Up Display to enable a pre-
cise display. A film in the windshield prevents
the double images fr om being displayed.
Windshield replacement should be carried out
by a BMW Sports Activity Vehicle Center or a
workshop that works according to BMW repair
procedures with correspondingly trained per-
sonnel.

Climate

By pressing the button repeatedly, you can
request three operating modes:
>
LED off: outside air flows in continuously.
> Left LED on, AUC mode: the system
detects pollutants in the outside air and
shuts off the supply as needed.
> Right LED on, recirculated-air mode: the
supply of outside air is permanently shut off.
Should the windows fog up in the recircu-
lated-air mode, press the AUTO button or
switch off the recirc ulated-air mode and
increase the air volume if necessary.
The recirculated-air mode should not be used
without interruption over an extended period of
time, as the air quality inside the vehicle deteri-
orates continuously. <
Residual heat
The heat stored in the engine is used to heat the
passenger compartment, e.g. while stopped at
a school to pick up a child.
Switching on
Pressing the right side switches on
the residual heat utilization when
the following conditions are met:
> up to 15 minutes after switching off the
engine
> with the engine at operating temperature
> with sufficient battery voltage
> at an outside temperature below 77 7/

pulted outwards and lead to injuries. <
Ventilation for cooling
Adjust the air vents to direct the flow of cool air
in your direction, for instance, if the interior has
become too warm, etc.
Draft-free ventilation
Set the air vents so that the air flows past you
and is not directed straight at you.

speed. This is the fastest way for the cold
engine to reach its operating temperature.
Thinking ahead when driving
Avoid unnecessary acceleration and braking.
To do so, maintain the appropriate distance
from the vehicle in front of you. An anticipatory
and smooth driving style reduces fuel con-
sumption.
Avoiding high engine speeds
Driving at a low engine speed reduces fuel con-
sumption and minimizes wear.
Taking advantage of coasting
The flow of fuel is interrupted when coasting.
Switching off engine during longer
stops
Switch off the engine at longer stops such as
traffic signals, railroad cr ossings, or in traffic
jams. Even having the en gine switched off for
approx. 4 seconds results in fuel savings.
Switching off functions currently not
required
Functions such as air conditioning, seat heat-
ing, or rear window defrosting consume a lot of
energy and require additional fuel. Their influ-
ence is particularly pron ounced in city traffic
and stop & go operation. For this reason, it is a
good idea to switch th ese functions off when
they are not really needed.
Having maintenance carried out
Have the vehicle serviced regularly in order to
achieve the optimum economy and service life
of your vehicle. BMW recommends having the
maintenance performed by a BMW Sports
Activity Vehicle Center. Also pay attention to
the BMW maintenance system, refer to
page 263.
General driving notes
Closing liftgate
Operate the vehicle only when the liftgate
is completely closed. Otherwise, exhaust
fumes could enter into the passenger compart-
ment. <
If it is absolutely necessa ry to drive with the lift-
gate open:
1. Close all windows as well as the glass sun-
roof
*/panorama glass sunroof*.
2. Increase the air volume of the automatic cli-
mate control to a high level, refer to
page 116.
Hot exhaust system
As in all vehicles, extremely high temper-
atures are generated on the exhaust sys-
tem. Do not remove the heat shields installed
adjacent to it, and neve r apply undercoating to
them. When driving, stan ding at idle and while
parking take care to avoid possible contact
between the hot exhaust system and any highly
flammable materials such as hay, leaves, grass,
etc. Such contact could lead to a fire, and with it
the risk of serious property damage as well as
personal injury. Do not touch hot tailpipes, as
otherwise there is a danger of burns. <
Diesel particulate filter*
Soot particles are collected in the diesel partic-
ulate filter and are periodically cleared out
through high-temperature combustion. This
cleaning process lasts fo r several minutes. You
may sometimes notice it by the fact that the
engine temporarily runs a little less smoothly
and requires a somewhat higher engine speed
to achieve the usual powe r. You may also notice
additional sounds and small amounts of smoke
coming from the exhaust, even for a brief time
after switching off the engine.
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-

Things to remember when driving
140
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.

Wheels and tires
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. <

Temperature
The temperature grades are A, the highest, B,
and C, representing the tire's resistance to the
generation of heat and its ability to dissipate
heat when tested under controlled conditions
on a specified indoor laboratory test wheel.
Sustained high temperature can cause the
material of the tire to degenerate and reduce
tire life, and excessive temperature can lead to
sudden tire failure. The grade C corresponds to
a level of performance which all passenger car
tires must meet under the Federal Motor Vehi-
cle Safety Standard No. 109. Grades B and A
represent higher levels of performance on the
laboratory test wheel than the minimum
required by law.
The temperature grade for this tire is
established for a tire that is properly
inflated and not overloaded. Excessive speed,
underinflation, or excessive loading, either sep-
arately or in combination, can cause heat
buildup and possible tire failure. <
RSC – run-flat tires
You will recognize run-flat tires by a circular
symbol containing the letters RSC on the side
of the tire, refer to page256.
M+S
Winter and all-season tires.
These have better winter properties than sum-
mer tires.
XL
Indicates specially reinforced tires.
Tire condition
Inspect your tires freq uently for tread wear,
signs of damage and for foreign objects lodged
in the tread. Check the tread depth.
Minimum tread depth
The tread depth should not drop below 0.12 in/
3 mm, although, for example, European legisla-
tion only specifies a minimum tread depth of 0.063 in/1.6 mm. At tread depths below 0.12 in/
3 mm there is an increased risk of high-speed
hydroplaning, even when only small amounts of
water are present on the road surface.
When winter tires wear down past a tread depth
of 0.16 in/4 mm, they become perceptibly less
suitable for winter conditions. For the sake of
safety, new tires should be installed.
Wear indicators at the tread-groove base are
distributed over the ti
re's circumference and
are marked on the side of the tire with TWI –
Tread Wear Indicator. If the tire tread has been
driven down to the we ar indicators, a tread
depth of 0.063 in/1.6 mm has been reached.
Wheel/tire damage
Please note that low-pr ofile tires cause wheels,
tires and suspension parts to be more suscep-
tible to road hazards and consequential dam-
ages.
Unusual vibrations encountered during normal
vehicle operation can indi cate tire failure or
some other vehicle defect. This can, for exam-
ple, be caused by driving over curbs. These
kinds of problems may also be signaled by other
changes in vehicle response, such as a strong
tendency to pull to the left or right.
In these cases, reduce speed immedi-
ately and have wheels and tires thor-
oughly checked. To do so , drive carefully to the
nearest BMW Sports Activity Vehicle Center or
tire shop that works ac cording to BMW repair
procedures with corres pondingly trained per-
sonnel. If necessary, have the vehicle towed
there. Otherwise, tire damage can be extremely
dangerous to vehicle occupants and other road
users. <
