Moving parts should be allowed to
break in. To ensure that your vehicle
provides maximum economy through-
out 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.
Avoid full-throttle operation and use of
the transmission's kick-down mode
during these initial miles.
Once you have driven 1,200 miles/
2,000 km, the engine and vehicle
speeds can be gradually increased.Tires Due to technical factors associated with
their manufacture, tires do not achieve
their full traction potential until after an
initial break-in period. Therefore, drive
reservedly during the first 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 hydroplaning and can
lead to partial or complete loss of trac-
tion, vehicle control and braking effec-
tiveness. Reduce your speed on wet
roads.<
Brake system Brakes require an initial break-in period
of approx. 300 miles/500 km to achieve
optimal contact and wear patterns
between brake pads and rotors.
To break in the separate handbrake
drums, apply the handbrake 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 handbrake 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,
when towing, for instance, substantially
higher levels of pedal force will be
required to brake the vehicle.<
ClutchThe function of the clutch is only at its
optimized level after a distance driven
of approx. 300 miles/500 km. During
this break-in period, engage the clutch
gently.Following component
replacementsObserve the break-in instructions again
if previously addressed components
must be replaced again during driving
later.

Driving your X5>Please note that, for example on
crests and bumpy roads, the body
can make ground contact.
The ground clearance of the vehicle
is:
– 8 in/20 cm with up to four persons
– 7 in/18 cm fully loaded, without
level control
>Only drive through water up to a max-
imum depth of 20 in/50 cm and only
at walking speed, making sure not to
stop in the process. When equipped
with 2-axle self leveling suspension
*,
switch the vehicle to the Off-Road
setting before driving through, refer
to page100.
After leaving the water, apply the
footbrake lightly several times while
driving at low speeds so as to dry
the brakes by braking and to prevent
decreased braking action due to wet-
ness.
Back onto 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 the worst of the dirt from the
body and inspect the undercarriage
for damage
>Clean mud, snow, ice etc. from the
wheels and tires and check the
wheels 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 handbrake, 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.

Safe braking Emergency stops You brake most effectively when you
apply maximum pedal pressure in situa-
tions requiring it: emergency stops.
Since the vehicle maintains steering
responsiveness, you can nevertheless
avoid possible obstacles with a mini-
mum of steering effort.
Pulsation at the brake pedal combined
with sounds from the hydraulic circuits
indicates to the driver that ABS is in its
active mode.Brake fluid level If the brake fluid level is too low and
brake pedal travel has become longer,
there may be a defect in one of the two
brake system's hydraulic circuits.
Proceed to the nearest BMW
Sports Activity Vehicle center.
Here increased pressure on the brake
pedal may be required, and slight pull-
ing to the side and longer braking dis-
tances may result. Please remember to
adapt your driving style accordingly.<
Disc brakes 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 to
form on rotors, while contaminants
accumulate on the brake pads. This
occurs because the minimal pressure
which must be exerted by the pads dur-
ing brake applications to clean the
rotors 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. 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 the brak-
ing force is then immediately 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 4-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.<
