Break-in proceduresTo ensure that your vehicle provides
maximum economy throughout a long
service life, we request that you
observe the following suggestions: Engine and axle drive 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:
BMW X5 3.0i: 100 mph (160 km/h)
BMW X5 4.4i: 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 if the engine or
one of the axle drives is replaced later
in the course of the vehicle service 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
complete 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 discs
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 shut off – when
towing, for instance – substantially
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 – 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.

General driving notes Catalytic converter
Brakes:
Do not drive with your foot resting
on the brake pedal. Even light but
consistent pedal pressure can lead to
high temperatures, brake wear and
possibly even brake failure.
Aquaplaning:
When driving on wet or slushy roads,
reduce vehicle speed. If you do not, a
wedge of water may form between the
tires and the road surface. This
phenomenon is referred to as aqua-
planing or hydroplaning. It is character-
ized by a partial or complete loss of
contact between the tires and the road
surface. The ultimate results are loss of
steering and braking control.
Cargo area cover:
Do not place heavy or hard objects on
the cargo area cover. These objects
could endanger vehicle occupants
during heavy brake applications or
evasive maneuvers.
Clothes hooks:
When suspending articles of clothing
from the hooks, be sure that they will
not obstruct the driver's vision. Do not
hang heavy objects on the hooks. If you
do so, they could cause personal injury
during braking or evasive maneuvers.< The catalytic converter reduces harmful
exhaust emissions.
It is designed for use with unleaded fuel
only. Even minute quantities of lead
would be enough to permanently
damage both the catalytic converter
and the system oxygen sensor.
To ensure efficient, trouble-free engine
operation and avoid potential damage:
>Be sure to comply with the scheduled
maintenance requirements.
>Fill the fuel tank well before it is
empty.
>Tow-start the vehicle only when the
engine is cold, since unburned fuel
may otherwise reach the catalytic
converter. It is better to start the
vehicle with an outside starting aid.
>Avoid other situations in which the
fuel is not burned, or burns incom-
pletely, such as engaging the starter
frequently or for extended periods, or
repeated start attempts in which the
engine does not start (stopping and
restarting an engine which is running
properly does not present a problem).
Never allow the engine to run with
any of the spark plug cables discon-
nected.

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.<

Antilock Brake System (ABS) In the event of a fault
If the brake warning lamp
comes on red together with the
yellow indicator lamps for ABS
and DSC (refer to pages 22
to 24), ABS, CBC, DSC, DBC,
EBV and HDC have failed. You
may continue driving, but drive
defensively and with extra
caution. Avoid full brake applications
because the vehicle could become
unstable and go out of control.
Have the system checked by the
nearest BMW center.
If all three warning lamps come on
yellow:
ABS, CBC, DSC, DBC and HDC have
failed. The effect of the EBV Brake
Force Distribution at the rear wheels,
which achieves stable brake response,
is largely preserved. Optimum brake
force and braking stability are no longer
assured. Continue to drive; drive
cautiously and defensively and avoid
full brake applications.
Have the system checked by your BMW
center as soon as possible.
Following an interruption in
battery power, the ABS, CBC,
DSC, DBC and HDC systems are no
longer available. After you drive for only
a few yards or meters or if you turn the
steering wheel from stop to stop while
the vehicle is stationary and the engine
is running, the functions are activated
again and the three warning lamps will
go out.<

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.<
