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 car. On bad roads When you are driving on bad roads,
there are a few points which you should
strictly heed Ñ 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 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 up-
hill 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 page 137
and 140.
When driving down steep slopes, use
the Hill Descent Control (HDC). Refer
to page 84. 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 ob-
stacles such as rocks or holes. Try to
avoid these obstacles whenever pos-
sible.
>On hill crests and bumpy roads, for
example, be careful to prevent the
body from "bottoming" (contact be-
tween the body and the ground).
The ground clearance of the vehicle
is:
Ð 8 inches (200 mm) with up to four
passengers
Ð 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 ap-
plications will help to dry the brakes,
thus preventing a reduction in brak-
ing performance caused by the mois-
ture.
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 ma-
terials 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 en-
dangered 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.

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 op-
erating conditions where brake applica-
tions are less frequent, there is an in-
creased tendency for corrosion of the
rotors and accumulation of contamina-
tion on the brake pads. This occurs be-
cause the minimal pressure which must
be exerted by the pads to clean the ro-
tors 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.
For your own safety: use only
brake pads that BMW has re-
leased for your particular vehicle
model. BMW cannot evaluate non-ap-
proved brake pads to determine if they
are suited for use, and therefore cannot
ensure the operating safety of the vehi-
cle 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 rotors.
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 124).
Extended or steep mountain descents
do not necessarily have to lead to re-
duced braking efficiency. Move the se-
lector lever to the appropriate lower
range in which only minimal periodic
brake applications are required.
You can increase the engine's braking
effect by selecting progressively lower
gears, downshifting as far as 1st gear,
on steep descents. If engine braking should prove to be in-
adequate, you should still avoid ex-
tended, continuous braking. Instead of
maintaining low to moderate pressure
over an extended period of time, you
should decelerate by applying more
substantial pressure to the brake pedal
(watch for following traffic), then releas-
ing the pedal, then repeating the appli-
cation. This staggered braking tech-
nique allows the brakes to cool in the
intervals between active braking
phases, preventing overheating and en-
suring that full braking capacity remains
available at all times.
Do not coast with the selector le-
ver in ÒNeutralÒ. Do not drive with
the engine shut off. The engine pro-
vides no braking effect when the trans-
mission is in ÒNeutralÒ, and there is no
power-assist for braking or steering
when the engine is not running.
Have brake inspections performed at
an authorized 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 accelerator and brake ped-
als and obstruct their movement.<

Caring for your vehicle Washing your vehicle You can have your new BMW washed
in an automatic car wash. Car wash
systems that do not employ brushes
are preferable.
Wipe away tough dirt and loosen and
remove dead insects before washing
the vehicle.
To prevent spots, avoid washing when
the hood is still warm, or immediately
after and during exposure to strong
sunlight.
When using an automatic car wash, be
sure that:
>The car wash system is suited for the
dimensions of your vehicle.
Before washing the vehicle in a
car wash, fold in the exterior mir-
rors manually, otherwise they may be
damaged on account of the width of the
vehicle.<
>No damage will occur on vehicles
with attached body accessories (such
as spoilers or antennas). If you are
uncertain, consult the manager of the
car wash.
>The wheels and tires of your vehicle
cannot be damaged by the convey-
ance devices of the car wash system.
>The vehicle is cleaned with minimum
brush pressure, and that ample water
is available for washing and rinsing.
Vehicles with rain sensor
*:
Clean the windshield regularly. Wax
from automatic car washes or insects,
for example, can cause malfunctions in
the function of the rain sensor.
Turn the rain sensor off in auto-
matic car washes. If you do not,
damage may occur if the wipers switch
on unintentionally.<
Parts of the vehicle that are inaccessi-
ble to the automatic washer Ñ such as
door sills, door and hood edges, etc. Ñ
should be cleaned by hand.
In the winter months, it is especially
important to ensure that the vehicle is
washed on a regular basis. Large quan-
tities of dirt and road salt are difficult to
remove, and they also cause damage to
the vehicle.
If spray wands or high-pressure
washers are used, be sure to
maintain an adequate distance between
the spray source and the vehicle's sur-
face. Inadequate distance and exces-
sive pressure can damage or weaken
the finish, making it more susceptible to
subsequent attack. In addition, mois-
ture could penetrate to vehicle compo-
nents, leading to long-term damage.<
When cleaning the headlamps,
please observe the following:
>Do not clean by wiping with a dry
cloth. Never use abrasives or strong
solvents to clean the covers.
>Remove dirt and contamination (such
as insects) by soaking with BMW Car
Shampoo and then rinsing with plenty
of water.
>Always use a deicer spray to remove
accumulated ice and snow Ð never
use a scraper.<
After washing the vehicle, apply
the brakes briefly to dry them.
Braking efficiency might otherwise be
reduced by the moisture and the brake
rotors could also be corroded.<
