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.<

Winter operation Power steering Level control system
*
Skid control Release the accelerator pedal and
depress the clutch pedal. Countersteer
carefully and attempt to regain control
of the vehicle.Parking Engage 1st or reverse gear. If your
vehicle is equipped with an automatic
transmission, place the selector lever in
"Park." On vehicles with manual trans-
mission, also apply the parking brake
when parking on inclined surfaces. In
order to prevent the parking brake pads
from locking due to frost or corrosion,
dry them by gently applying the parking
brake as the vehicle is coming to a
stop. Make sure that following traffic is
not endangered.
The brake lamps do not light up
when the parking brake is
applied.<
If there is a change in steering response
(difficult steering, for example) or, espe-
cially on vehicles with Servotronic
*, if
the steering "drifts" or "floats" at
increasing speeds:
Have your BMW center inspect this
system as soon as possible.
If the power steering fails,
increased effort will be required to
steer the vehicle.<
The warning lamp for the level
control system comes on, or the
message SELFLEVEL
SUSP.INACT appears in the Check
Control: There is a malfunction in the
level control system.
Stop and inspect the vehicle. If it is
riding significantly lower in the rear than
in the front, or if it is sitting at an incline
(left rear compared to right rear),
consult the nearest BMW center. Drive
with appropriate caution in the mean-
time, especially if you are driving under
poor road-surface conditions. The
vehicle has reduced ground clearance
or driving comfort is noticeably
reduced.
Even if the attitude of the vehicle is
normal, you should consult the nearest
BMW center if the warning lamp indi-
cates a system fault.

Engine oilChecking oil level1 Park the vehicle on a level surface.
2 Shut the engine off after it has
reached normal operating tempera-
ture.
3 After approx. 5 minutes, pull the
dipstick out and wipe it off with a
clean lint-free cloth, paper towel, or
similar material.
4 Push the dipstick carefully all the way
into the guide tube and pull it out
again.
5 The oil level should be in between the
two marks on the dipstick.
As with fuel economy, oil consumption
is directly influenced by your driving
style and vehicle operating conditions. 530us100
The oil volume between the two marks
on the dipstick corresponds to approx.
1.1 US quarts (1 liter). Do not fill beyond
the upper mark on the dipstick. Excess
oil will damage the engine.530us205
Adding engine oilWait until the level has dropped to just
above the lower mark before adding oil.
However, do not wait until the oil level
drops below the lower mark.
BMW engines are designed to
operate without oil additives; the
use of additives could lead to damage
in some cases. This is also true for the
manual transmission, the automatic
transmission, the differential, and the
power steering system.< 530us101

Changing a wheel
Safety measures in the event of a
flat tire or wheel change: stop the
vehicle as far as possible from passing
traffic. Park on a firm, flat, surface.
Switch on the hazard warning flashers.
Turn the steering wheel to the straight-
ahead position, remove the key and
engage the steering lock. Shift into 1st or
reverse (selector lever in "Park" with
automatic transmission) and engage the
parking brake. All passengers should be
outside the vehicle and well away from
your immediate working area (behind a
guardrail, for instance). If a warning
triangle or portable hazard warning lamp
is required, set it up on the roadside at
an appropriate distance from the rear of
the vehicle. Comply with all safety guide-
lines and regulations. Change the wheel
only on a level, firm surface which is not
slippery. Avoid jacking the vehicle up on
a soft or slippery surface (snow, ice, very
smooth surfaces, etc.), since it could
slide sideways. Position the jack on a
firm support surface. Do not place
wooden blocks or similar objects under
the jack. If this is done, the jack might not
be able to reach its full support capacity
because of the limited height. Do not lie
under the vehicle or start the engine
when the vehicle is supported by the
jack. Failure to comply with this creates a
risk of fatal injury.<
What you will need In order to avoid rattling noises later,
note the position of the tools when you
remove them and return them to their
original position when you are through
using them.
>Two wedges (wheel chocks)
Open the liftgate and tailgate.
In the cargo area, fold up the floor
cover or pull-out cargo floor (refer to
page 127 or 128).
Take out the wedges (arrow) next to
the spare wheel. 530us117

Towing the vehicle
The towed vehicle should always
be the lighter of the two vehicles.
If this is not the case, it is no longer
possible to control vehicle response.<
Tow-starting It is not possible to start the engine of a
vehicle equipped with an automatic
transmission by towing or pushing.
For instructions on jump starting: refer
to page 190.
Never attempt to use your vehicle to
push another car. If you do so, damage
to the energy-absorbing bumpers could
result.
Towing a vehicle with automatic
transmission1 Place the selector lever in position N.
2 Towing speed:
Max. 45 mph (70 km/h).
3 Towing distance:
Max. 95 miles (150 km).
4 Leave the ignition key at position 1 to
ensure that the brake lamps, turn
signals, horn and windshield wipers
remain operative, and to prevent the
steering lock from engaging.
5 Switch on the hazard warning
flashers (comply with country-
specific regulations).
Find some means of identifying the
vehicle in tow, for instance, place a sign
or warning triangle in the rear window.
Make sure that the ignition key
remains in position 1 even when
the electrical system has failed. This will
prevent the steering lock from
engaging. The steering and brakes are
without power assist when the engine is
not running. This means that increased
effort is required for steering and
braking.<
Towing with a commercial tow
truck>Do not tow with sling-type equip-
ment.
>Use a wheel lift or flat bed carrier.
>Please comply with applicable towing
laws.
Never allow passengers to ride in
a towed vehicle for any reason.< 530us138

Deceleration sensors continuously
monitor the physical forces acting upon
the vehicle. If, as the result of a frontal
impact, vehicle deceleration is reached
at which the protection of the safety
belts alone is no longer adequate, the
gas generators of the driver-side and
passenger-side airbags are ignited
simultaneously. However, the
passenger-side airbag is only triggered
if an additional sensor has recognized
that the passenger seat is occupied.
Depending on which side the of vehicle
is involved in a side collision, the head
protection and side airbags in the front
and rear
* on that side are triggered if
necessary.
390de319
The airbags located under the marked
covers inflate and unfold in a matter of
a few milliseconds. In this process, they
tear through the designed separation
points of the upholstered covers or
press them out.
Because the inflation process must be
virtually instantaneous, it is necessarily
accompanied by a certain amount of
ignition and inflation noise. The gas
required to inflate the airbags is not
dangerous, and the associated smoke
then dissipates.
The entire process is completed within
fractions of a second. On vehicles with an automatic trans-
mission, Adaptive Transmission Control
(ATC) uses a number of factors to
calculate the gear which provides the
maximum efficiency. In this process,
the system monitors your personal
driving style, the driving situation, the
condition of the road, and the traffic
conditions.
ATC recognizes your personal driving
style from the positions and movements
of the accelerator pedal, deceleration
when braking, and lateral acceleration
through curves. Four different shift
characteristics – from comfort-oriented
to performance-oriented – are available
for selection by ATC.

The transmission of power to the four
drive wheels is provided permanently
through a transfer box. The distribution
of torque between the front and rear
axles is 38% to 62%.
Traditional differential locks at the front
and rear axles and in the transfer box
are not required. Their function is taken
over by automatic braking intervention
at all four wheels. These traction inter-
ventions are governed by Automatic
Differential Brake (ADB-X), a sub-func-
tion of DSC.
If a wheel tends to slip, it is braked
automatically by ADB-X until it once
again gains traction, and drive force
can be transmitted to that wheel. In
addition, the drive force is distributed
to the remaining wheels during this
530us133
system intervention. Engine output is
also reduced if necessary.
When the DSC is deactivated, the
ADB-X traction intervention is set for
the maximum drive force. However,
the engine intervention and the stability
controls are no longer available. For
this reason, DSC should only be deacti-
vated in the exceptional circumstances
described on page 95.
The BMW X5 is a vehicle for all types of
roads. The permanent four-wheel drive
provides a significant degree of vehicle
stability and tractive power under all
road conditions. It assists in critical
situations such as driving in extreme
winter conditions or on bad roads. Precision sensors monitor the wheel
speeds, the steering angle, lateral
acceleration, brake pressure and the
movement of the vehicle around its
vertical axis.
If differences in wheel speeds occur, the
system recognizes the danger of wheel-
spin and reduces the engine's drive
torque. If necessary, the system also
responds with additional braking inter-
vention at all four wheels.
In addition, DSC permanently monitors
the vehicle's current operating condition
and compares it with an ideal condition
that is calculated from the sensor
signals. If deviations from this occur
(understeering or oversteering, for
instance), DSC can stabilize the vehicle
in fractions of a second by adapting
engine output and with the assistance of
braking intervention at individual
wheels. This way, as long as the skid
can still be managed under the laws of
physics, these kinds of dangerous skids
are prevented even before they can
start.
You may need some time to become
accustomed to this system intervention.
However, it provides optimum drive
force and vehicle stability. The braking
intervention may be accompanied by
certain sounds specific to the system.
