Tips for pleasant drivingUse the automatic system; that is press
AUTO button 6. Select an interior
temperature that is comfortable for you
— we recommend +72 7 (+22 6).
When the outside temperature is above
+41 7 (+5 6), you can also use the air
conditioner 12. This will dry the air as
well as preventing condensation on the
window surfaces — if there are passen-
gers with damp clothing, for example.
Set the air outlets 2 so that the air flows
past you and is not directed straight at
you. Set the rotary dial between the
outlets 2 for the upper body to a central
position so that cooler air will help to
prevent fatigue during the journey.
Detailed setting options are described
for you in the following section.
Your vehicle is set in such a
manner that, when you unlock the
vehicle via remote control with your
personalized key, your own setting for
the automatic climate control is initi-
ated.<
Automatic air distribution
The AUTO program
assumes the adjustment of
the air distribution and the air supply for
you and also adapts the temperature to
external influences (summer, winter) to
meet preferences you can specify. This
program maintains a comfortable in-car
climate regardless of the season. Select
an interior temperature that is comfort-
able for you — we recommend +72 7
(+22 6).
The selected temperature and AUTO
for the air flow appear in the display 9.
Refer to the overview on page 106.
Open the air outlets for the upper body.
Switch on the air conditioner 12 in
warm weather. The maximum cooling
capacity is achieved when you set
rotary dial 3 (refer to page 110) to cold.
Individual air distribution
You can cancel the AUTO
program by selecting
specific air distribution
patterns for your personal
comfort. You can direct air
to flow onto the windows , toward
the upper body , and into the
footwell .
Temperature
You can make individual
temperature adjustments on
the driver's side or the front
passenger side. Your settings will be
shown in the display 9. The displayed
temperatures are reference values for
the interior temperature. We recom-
mend +72 7 (+22 6) as a comfortable
setting, whether the air conditioner is
operating or not. When you start the
vehicle, this system ensures that the
selected temperature is achieved as
quickly as possible. It then maintains
this temperature, regardless of the
season.
Set the rotary dial 3 (refer to "Draft-free
ventilation" on page 110) to a medium
position to provide somewhat cooler
air. This helps to promote driving
without fatigue. Utilize this method of
mixing air especially for making minor
adjustments for personal comfort.
You can set uncontrolled heater
output up to +90 7 (+32 6). Full
cooling output is available from the air
conditioner down to +60 7 (+16 6).<

Air supply
In the AUTO program, the
air flow is controlled auto-
matically. AUTO will appear in the
display 9 (refer to the overview on
page 106). Use "+" and "–" to vary the
airflow. When your setting is displayed
by bars, the automatic airflow is
switched off. Automatic air distribution
maintains its setting. You can reactivate
the automatic air supply by pressing the
AUTO button.
When you press "– " during operation at
minimum blower speed all displays are
canceled: the blower, heating and air
conditioner are switched off. The
outside air supply is closed. You can
switch the system back on by pressing
any button of the automatic climate
control.
To defrost windows and remove
condensation
This program quickly
removes ice and conden-
sation from the windshield and the side
windows.
Air conditioner
The air is cooled and
dehumidified and —
depending on the temperature setting —
warmed again when the air conditioner
system is switched on. Depending on
the weather, the windshield may fog
over briefly when the engine is started.
Use the button to switch the air condi-
tioner off at outside temperatures
below approx. +41 7(+5 6). This will
help to prevent the windows from
fogging over.
If the windows fog over after switching
the air conditioner off, switch it back
on.
Condensation forms in the air
conditioner system during opera-
tion, which then exits under the vehicle.
Traces of condensed water of this kind
are thus normal.<
Maximum cooling
You will get maximum
cooling capacity using this
program if the engine is running and
the outside temperature is above
+41 7(+5 6).
The temperature display 9 drops to
+61 7 (+16 6), the system switches
over to the recirculated-air mode, and
the air streams out of the ventilation grill
with the maximum amount of flow. 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 airflow 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 airflow
operational.
>Left-hand indicator lamp on – 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
flow of external air into the vehicle is
completely blocked. The system then
recirculates the air currently within
the vehicle.
If you have a multifunction steering
wheel with the button for recirculated
air (refer to page 26), 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 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.
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.<

Driving your BMW X5 Your BMW is right at home on all roads
and byways – even where the pavement
ends. It combines permanent four-
wheel drive with the agility of a typical
passenger car. On bad roadsWhen you are driving on bad roads,
there are a few points which you should
strictly heed — for your own safety, for
that of your passengers, and for the
safekeeping of the vehicle:
>Familiarize yourself with the vehicle
before you begin driving. Do not take
risks with the vehicle under any
circumstances.
>Always adapt vehicle speed to road
conditions – 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 157
and 160.
When driving down steep slopes, use
the Hill Descent Control (HDC). Refer
to page 95. 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" (contact
between the body and the ground).
The ground clearance of the vehicle
is:
– 8 inches (200 mm) with up to four
passengers
– 7 inches (180 mm) fully loaded.
>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 discs and calipers could influ-
ence braking performance. Remove
all such foreign objects.
>In order to clean the brake discs,
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),
provided that traffic conditions allow
you to do so.

Catalytic converter Antilock Brake System (ABS)
Be sure to comply with the
instructions above to prevent
unburned fuel from reaching the cata-
lytic converter. Otherwise, the catalytic
converter could respond by over-
heating, leading to serious damage.
Extreme temperatures occur at the
catalytic converter on this and every
catalyst-equipped vehicle. Heat shields
are installed adjacent to some sections
of the exhaust system. Never remove
these shields; do not apply under-
coating to their surfaces. When driving,
standing at idle, and parking the
vehicle, take care to avoid contact
between the exhaust system and flam-
mable materials (grass, hay, leaves,
etc.). Such contact could lead to a fire,
resulting in serious personal injury and
property damage.<
The concept ABS enhances active safety by helping
to prevent the wheels from locking
under braking. This is because: locked
wheels are dangerous. When the front
wheels slide, the driver loses steering
control over the vehicle. Traction loss at
the rear wheels can cause the rear end
to break into an uncontrolled skid.
With ABS, you will achieve the shortest-
possible braking distances under all
given conditions (braking while driving
straight ahead or in curves, different
road surfaces).
ABS is designed to meet two essential
requirements during every brake appli-
cation:
>To help provide vehicle stability.
>To help retain steering and maneu-
vering capability on all types of road
surfaces (asphalt, cement, dirt, wet
surfaces, snow and ice).
Braking with ABS The system becomes operative once
the vehicle exceeds a speed of approx.
6 mph (10 km/h). The ABS is inactive
again whenever the vehicle's speed
drops back below approx. 4 mph
(6 km/h).
To shorten the braking distance — espe-
cially on steep, poor road surfaces when
driving slowly straight ahead — the
system allows one or both front wheels
to lock for a short time. Nevertheless,
the vehicle still retains steering
response since this "poor road logic" is
deactivated again automatically as you
steer.
If you are in a situation that requires full
braking, you will exploit the full benefits
of the ABS system if you apply maxi-
mum brake pressure ("panic stop").
Since the vehicle maintains steering
responsiveness, you can avoid possible
obstacles with a minimum of steering
effort, despite the full brake application.
The ABS system's closed-loop control
circuit cycles in fractions of a second.
A pulsation at the brake pedal, together
with the sounds associated with the
hydraulic controls, tells you that the
brake system is within its maximum
limit range and reminds you that you

138n
Antilock Brake System (ABS)should adapt road speed to the road
conditions.
On road surfaces that have a loose
surface layer on a firm base with good
traction (on gravel, deep sand or snow,
for example), braking distances may be
longer than with locked wheels.This is
also true if snow chains are mounted.
However, ABS continues to provide
enhanced vehicle stability and steering
response under these conditions. Information for your safety Not even ABS can suspend the laws of
physics. ABS alone cannot prevent
accidents when the brakes are applied
without an adequate safety distance
between vehicles, if the vehicle is
driven with excessive speed, or if aqua-
planing occurs. Responsibility for these
types of situations remains in the hands
(and at the feet) of the driver. You
should never allow the added safety of
ABS to lull you into a false sense of
security, or mislead you into taking
increased risks that could affect your
own safety and that of others.
Do not make any modifications to
the ABS system.
Service procedures on ABS are to be
performed by authorized technicians
only.<
Cornering Brake Control (CBC) CBC is an advanced engineering
design of the ABS. When braking
during cornering with high lateral accel-
eration, or when braking during a lane
change, vehicle stability is further
improved and the steering response is
enhanced. Electronic Brake Force
Distribution (EBV) EBV governs brake application pres-
sure at the rear wheels to achieve
stable brake response.
If the EBV fails (refer to the next
page), avoid full or "panic" brake
applications. Full or panic brake appli-
cations can result in overbraking at the
rear axle, and braking stability is no
longer ensured.<
Dynamic Brake Control (DBC)

If you apply the brakes rapidly, this
system automatically produces the
maximum braking force boost and thus
helps to achieve the shortest possible
braking distance during "panic stops."
All of the benefits of the ABS system
are exploited under these circum-
stances.
Do not reduce the pressure on the
brake pedal for the duration of the
brake application. When the brake
pedal is released, the DBC is deacti-
vated.
In the event of a malfunction,
the yellow warning lamp comes
on. Have the system checked
and repaired at your BMW
center as soon as possible.
Refer to the "Information for your
safety" covering the ABS system.
This information also applies in general
for DBC.<

140n
Disc brakes Disc brakes furnish optimum decelera-
tion and braking control and greater
fade resistance under heavy use.
When 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
discs 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 discs are corroded, they will
tend to respond to braking with a
pulsating effect which even extended
application will fail to cure.
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.<
Driving notes When driving in wet conditions and in
heavy rain, it is advisable to apply light
pressure to the brake pedal every few
miles (kilometers). Watch traffic condi-
tions to ensure that this maneuver does
not endanger other road users. The
heat which is generated by the brake
applications helps to dry the brake
pads and discs.
Maximum braking force is obtained
while the wheels continue to rotate,
peaking when the wheels remain on the
verge of locking without actually doing
so. ABS maintains this state automati-
cally. If the ABS fails, you should revert
to the staggered braking technique
(refer to page 142).
Extended or steep mountain descents
should be driven in the gear in which
only minimal periodic brake applica-
tions is required. This avoids excessive
strain on the brakes and possible
impairment of the braking effect.
You can further increase the engine's
braking effect by selecting a lower gear,
downshifting as far as first gear.
When driving a vehicle with automatic
transmission, you can still downshift
into first gear. Refer to page 69.If engine braking should prove to be
inadequate, you should still avoid
extended, continuous braking. Instead
of maintaining low to moderate pres-
sure over an extended period of time,
you should decelerate by applying
more substantial pressure to the brake
pedal (watch for following traffic), then
releasing the pedal, then repeating the
application. This staggered braking
technique allows the brakes to cool in
the intervals between active braking
phases, preventing overheating and
ensuring that full braking capacity
remains available at all times.
Do not coast with the clutch
depressed or with the transmis-
sion or selector lever in neutral. Do not
drive with the engine shut 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.
Have brake inspections performed at
an BMW 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 accel-
erator, clutch and brake pedals and
obstruct their movement.<
