Tire Pressure Monitor RDC*The conceptRDC monitors the tire pressures at all
four tires, even when the vehicle is
moving. The system provides an alert
whenever the inflation pressure drops
significantly below the specified pres-
sure in one or more tires.
In order for the system to learn the cor-
rect tire inflation pressure, check the
inflation pressures in all tires, refer to
the table on page 27 and make any
necessary corrections. Then activate
the system.
This indicator lamp in the instru-
ment cluster or the Check Con-
trol will inform you if the tire
pressure is different from the learned
values.
To switch the system on1. Turn the ignition key to position 2, do
not start the engine
2. Maintain pressure on the button until
the yellow indicator lamp in the
instrument cluster comes on for sev-
eral seconds or the message Ð TIRE
PRESSURE SET Ð appears in the
Check Control
3. After you have driven for a few min-
utes, the RDC will import the current
inflation pressure in the tires as the
reference values which the system
will monitor.
You will only have to repeat this proce-
dure if the tire inflation pressure must
be corrected. Otherwise, the RDC func-
tions automatically when the ignition
key is in position 2, and thus operates
whenever the vehicle is driven.530de232
Loss of tire pressureIf, after a certain period of time, the
inflation pressure has gone down sig-
nificantly, which is normal for any tire,
the yellow indicator lamp comes on or
the message Ð CHECK TIRE PRES-
SURE Ð appears in the Check Control.
This alerts you that you should have the
tires inflated to the specified pressures
as soon as possible.
If you are prompted to check the
tire pressure shortly after a cor-
rection has been made, this indicates
that the corrected values were not
accurate. Please check the inflation
pressure again and make corrections
according to the inflation pressure
table. After that reactivate the system.<

Air conditioner Temperature
The graduations on the dial
provide general reference
values for the interior temper-
ature. We recommend
+70 7/+22 6 as a comfortable
setting. When you start the vehicle, the
system adjusts the air to the selected
temperature as quickly as possible, and
then maintains that temperature
constantly.
Air distribution
You can direct air to flow onto
the windows , toward the
upper body and into the
footwell . All intermediate
settings are possible. In the setting,
there is a low flow of air onto the
windows to keep them free of conden-
sation.
Air supply
You can adjust the air supply
through an infinitely-variable
range. The heating and venti-
lation become more and more
effective as the air supply settings are
increased. In the 0 setting, the blower
and climate control are switched off
and the outside air supply is blocked.
Rear window defroster
When the rear window
defroster is activated, the
indicator lamp comes on. The rear
window defroster switches off automat-
ically.
Air conditioning
The air is cooled and dehu-
midified and Ñ depending on
the temperature setting Ñ warmed
again. Depending on the weather, the
windshield may fog over briefly when
the engine is started. You can reduce
condensation forming on the windows
by switching on the air conditioning.
During air conditioning condensa-
tion forms, which then exits under
the vehicle. Traces of condensed water
of this kind are thus normal.<
Recirculated-air mode
You can respond to unpleas-
ant odors outside the vehicle
by temporarily switching off the outside
air supply. The system then recirculates
the air currently within the vehicle.
If you have a steering wheel with multi-
function buttons with the button for the
recirculated-air mode, you can also use
this button to switch to the recirculated-
air mode, refer to page 23.
If the windows fog over in the
recirculated-air mode, switch the
recirculated-air mode off and increase
the air supply as required.<

Maximum cooling
You will get maximum
cooling capacity using this
program if the engine is running and
the outside temperature is above
approx. +41 7/+5 6.
The temperature display 9 jumps to
+60 7/+16 6, the system switches
over to the recirculated-air mode, and
the air streams out of the ventilation grill
with the maximum air supply. That is
why you need to keep these open if you
select this program.
Automatic recirculated-air
control AUC
If there are unpleasant
odors or pollutants in the
outside air, you can temporarily block
the air supply from the outside. The
system then recirculates the air
currently within the vehicle. Press the
button repeatedly to run through the
following control sequence
>Indicator lamps off: outside air supply
operational
>Left-hand indicator lamp on Ð AUC
mode: the system recognizes pollut-
ants in the outside air and blocks the
flow of air when necessary. The
system then recirculates the air
currently within the vehicle.
Depending on the air quality, the
automatic system then switches back
and forth between outside air supply
and recirculation of the air within the
vehicle
>Right-hand indicator lamp on: the
outside air supply into the vehicle is
completely blocked. The system then
recirculates the air currently within
the vehicle.
If you have a steering wheel with multi-
function buttons with the button for
recirculated-air mode, refer to page 23,
you can also use this button to switch
between Off and the recirculated-air
mode or AUC and the recirculated-air
mode.
If the windows fog over in the
recirculated-air mode, switch the
recirculated-air mode off and increase
the air supply as required.< Rear window defroster
When the rear window
defroster is activated,
the indicator lamp comes on. The
rear window defroster switches off
automatically.

Automatic climate control
*
Residual heat mode
The heat which is stored in
the engine is utilized for
heating the interior when the engine
has been switched off (while waiting at
a railroad crossing, for instance).
In ignition key position 1, you can alter
the settings of the automatic climate
control. With the ignition key in posi-
tion 0, the system automatically directs
heated air to the windshield, side
windows and footwells.
This function may be activated
when the outside temperature is
below approx. 59 7/15 6, the engine
is at operating temperature, and the
battery is adequately charged. The LED
on the button will light up when all
conditions have been met.<
Draft-free ventilation You can adjust the vent outlets for the
upper body area to select the optimum
airflow rates and directions for your
personal comfort:
1 Rotary dials for opening and closing
the vent outlets through an infinitely-
variable range
2 Selector levers for airflow direction
3 With the rotary dial you can adjust the
temperature of the incoming air.

Break-in proceduresTo 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 speeds and
road speeds, but do not exceed
4,500 rpm and the following road
speeds during this initial period:
6-cylinder engines: 100 mph/160 km/h
8-cylinder engines: 106 mph/170 km/h
Obey your local and state maximum
speed limits.
Refrain from using full throttle and avoid
pressing the accelerator beyond the
kickdown point.
Once you have driven 1,200 miles/
2,000 km, engine and vehicle speeds
can gradually be increased.
You should also comply with these
break-in procedures should the engine
or one of the differentials be replaced
later in the course of the vehicle's ser-
vice life.
TiresDue to technical factors associated
with their manufacture, tires do not
achieve their full traction potential until
an initial break-in period has elapsed.
For this reason, drive with extra care
during the initial 200 miles/300 km.
Obey your local and state maximum
speed limits.
When the vehicle is operated on
wet or slushy roads, a wedge of
water may form between the tire and
the road surface. This phenomenon is
referred to as aquaplaning, or hydro-
planing, and can lead to partial or com-
plete loss of traction, vehicle control
and braking effectiveness. Reduce your
speed on wet roads.<
Brake systemApprox. 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 parking brake
drums, apply the parking brake lightly
when coasting to a standstill at a traffic
signal, for instance, provided that traffic
conditions allow you to do so.
To avoid corrosion, repeat this proce-
dure from time to time.
The brake lamps do not light up
when the parking brake 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 switched off Ð
when towing, for instance Ð substan-
tially higher levels of pedal force will be
required to brake the vehicle.<

Driving your BMW X5 Your BMW is right at home on all roads
and byways Ð even where the pavement
ends. It combines permanent four-
wheel drive with the agility of a typical
passenger vehicle. On bad roadsWhen you are driving on bad roads,
there are a few points which you should
strictly observe Ñ for your own safety,
for that of your passengers, and for the
safety of the vehicle:
>Familiarize yourself with the vehicle
before you begin driving. Do not take
risks with the vehicle under any cir-
cumstances
>Always adapt vehicle speed to road
conditions Ð the steeper and more
uneven the road surface is, the
slower the vehicle's speed should be
>You can operate your vehicle on
uphill and downhill gradients with a
maximum slope of 50 %. If you intend
to drive on either an uphill or downhill
gradient of this steepness, check to
be sure in advance that the engine oil
and coolant levels are both near the
MAX mark, refer to pages 141
and 143.
When driving down steep slopes, use
the Hill Descent Control HDC, refer to
page 93. Starting from a full stop is possible on
uphill gradients of up to 32 %.
The permitted side tilt is also 50 %
>While driving, watch carefully for
obstacles such as rocks or holes. Try
to avoid these obstacles whenever
possible
>On hill crests and bumpy roads, for
example, be careful to prevent the
body from bottoming Ð contact
between the body and the ground.
The ground clearance of the vehicle
is:
8 in/200 mm with up to four
passengers
7 in/180 mm fully loaded Ð without
self-leveling suspension
>Do not drive in water that is deeper
than 20 inches/50 cm. If you must
drive through water up to that depth,
drive at a walking speed and do not
stop.
After leaving the water, press on the
footbrake gently several times while
driving at a low speed. The brake
applications will help to dry the
brakes, thus preventing a reduction in
braking performance caused by the
moisture.
Back onto the paved road In recommending that you observe the
following points after driving on adverse
road surfaces, it is not as a beauty
treatment for your BMW. Instead, it is
intended for the maintenance of driving
safety:
>Clean accumulations of dirt from the
body and check the undercarriage for
damage
>Clean mud, snow, ice and other
materials from the wheels and tires.
Check the tires for damage
>Check to determine whether rocks,
gravel or accumulations of dirt on the
brake rotors and calipers could influ-
ence braking performance. Remove
all such foreign objects
>In order to clean the brake rotors,
apply the footbrake gently several
times while driving at a low speed. Be
sure that following traffic is not
endangered by this
>For cleaning the parking brake, apply
the lever slightly at approx. 25 mph/
40 km/h and continue to drive for
approx. 200 yards/200 meters, pro-
vided that traffic conditions allow you
to do so.

OverviewControlsMaintenanceRepairsDataIndex
Brake systemDisc brakesWhen the vehicle is driven only occa-
sionally, during extended periods when
the vehicle is not used at all, and in
operating conditions where brake appli-
cations are less frequent, there is an
increased tendency for corrosion of the
rotors and accumulation of contamina-
tion on the brake pads. This occurs
because the minimal pressure which
must be exerted by the pads to clean
the discs by brake applications is not
reached.
If the brake rotors are corroded, they
will tend to respond to braking with a
pulsating effect which even extended
application will fail to cure.
When driving in wet conditions and in
heavy rain, it is advisable to apply light
pressure to the brake pedal from time
to time. Watch traffic conditions to
ensure that this maneuver does not
endanger other road users. The heat
which is generated by the brake appli-
cations helps to dry the brake pads and
rotors. The braking force is then imme-
diately available when required.Extended or steep mountain descents
should be driven in the gear in which
only minimal periodic brake application
is required. This avoids excessive strain
on the brakes and possible impairment
of the braking effect.
Do not coast with the clutch
depressed or with the transmis-
sion or selector lever in neutral. Do not
drive with the engine switched off. The
engine provides no braking effect when
the clutch is depressed or the transmis-
sion is in neutral, and there is no
power-assist for braking or steering
when the engine is not running.
BMW recommends having brake
inspections performed at a BMW
Sports Activity Vehicle center only. If
you do not, parts of the four-wheel
drive system could be damaged.
Never allow floor mats, carpets or any
other objects to protrude into the area
around the accelerator, clutch and
brake pedals and obstruct their move-
ment.<
Brake pads
For your own safety: use only
brake pads that BMW has
released for your particular vehicle
model. BMW cannot evaluate non-
approved brake pads to determine if
they are suited for use, and therefore
cannot ensure the operating safety of
the vehicle if they are installed.<
