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.<

DOT code:Tire age The manufacturer of your BMW recom-
mends that all tires, i.e. including the
spare wheel, be replaced regardless of
the actual wear after 6 years at the lat-
est.
The tire's date of manufacture is indi-
cated on the sidewall:
DOT... 3603 indicates that the tire was
manufactured in week 36 of 2003. Uniform Tire Quality Grading Quality grades can be found where
applicable on the tire sidewall between
tread shoulder and maximum section
width. For example: e.g.
Manufacturer's code
for tire brand
Tire size and tire model
Tire age
DOT xxxx xxx 3603
DOT Quality Grades Tread wear
Traction AA A B C
Temperature A B C
All passenger car tires must con-
form to Federal Safety Require-
ments in addition to these grades.< Tread wear The tread wear grade is a comparative
rating based on the wear rate of the tire
when tested under controlled condi-
tions on a specified government test
course.
For example, a tire graded 150 would
wear one and one-half, 1γ, times as
well on the government course as a tire
graded 100. The relative performance
of tires depends upon the actual condi-
tions of their use, however, and may
depart significantly from the norm due
to variations in driving habits, service
practices and differences in road char-
acteristics and climate.

Tire identification marks Wheel/tire condition Traction The traction grades, from highest to
lowest, are AA, A, B, and C.
Those grades represent the tire's ability
to stop on wet pavement as measured
under controlled conditions on speci-
fied government test surfaces of
asphalt and concrete. A tire marked C
may have poor traction performance.
The traction grade assigned to
this tire is based on straight-ahead
braking traction tests, and does not
include acceleration, cornering, hydro-
planing, or peak traction characteris-
tics.< TemperatureThe temperature grades are A, the
highest, B, and C, representing the
tire's resistance to the generation of
heat and its ability to dissipate heat
when tested under controlled condi-
tions on a specified indoor laboratory
test wheel.
Sustained high temperature can cause
the material of the tire to degenerate
and reduce tire life, and excessive tem-
perature can lead to a sudden flat tire.
The grade C corresponds to a level of
performance which all passenger car
tires must meet under the Federal
Motor Vehicle Safety Standard No. 109.
Grades B and A represent higher levels
of performance on the laboratory test
wheel than the minimum required by
law.
The temperature grade for this tire
is established for a tire that is
properly inflated and not overloaded.
Excessive speed, underinflation, or
excessive loading, either separately or
in combination, can cause heat buildup
and possible a tire failure.< M+SWinter and all-season tires.
These have better winter properties
than summer tires.
Wheel/tire damage Inspect your wheels and tires frequently
for tread wear, signs of damage and for
foreign objects lodged in the tread.
Check the tread pattern depth.
Please note that low-profile tires
make your wheels, tires and sus-
pension parts more susceptible to road
hazard and consequential damages.
Unusual vibrations encountered during
normal vehicle operation can indicate
tire failure or some other vehicle defect.
This can, for example, be caused by
driving over curbs. This is also true for
irregularities in the vehicle's handling
characteristics, such as a pronounced
tendency to pull to the left or right.
Should this occur, respond by immedi-
ately reducing your speed. Carefully
proceed – or have your vehicle towed –
to the nearest BMW Sports Activity
Vehicle center or tire dealer to have the
wheels or tires inspected.
Tire damage, extending to sudden and
complete loss of pressure in extreme
cases, can pose a potentially lethal
safety hazard for the vehicle's occu-
pants and other road users alike.<

Wheel/tire conditionTire tread The tread depth should not fall below
0.12 in/3 mm although, for example,
European regulations only require a
minimum tread depth of 0.063 in/
1.6 mm.
At tread depths below 0.12 in/3 mm
there is an increased risk of high-speed
hydroplaning, even when only small
amounts of water are present on the
road surface.
As winter tires display a noticeable loss
in their ability to cope with cold-
weather driving conditions once the
tread wears to below 0.16 in/4 mm, you
should always have such tires replaced
to ensure continued safety.Wear indicators at the tread-groove
base, refer to arrow, are distributed
over the tire's circumference and are
marked on the side of the tire with TWI
– Tread Wear Indicator. These indica-
tors signal at a tread depth of 0.063 in/
1.6 mm that the legally permitted wear
limit has been reached.

Replacing wheels/tires
Have new wheels and tires
installed only by your BMW Sports
Activity Vehicle center or a tire special-
ist workshop that works according to
BMW guidelines with appropriately
trained personnel. If this work is not
carried out properly, there is a danger
of subsequent damage and related
safety hazards.<
Retreaded tires
BMW does not recommend the
use of retread tires, as otherwise
driving safety may be reduced. The rea-
son for this is that possible variations in
the design and aging – which could be
substantial – of the tire casing can
result in a limited service life.<
The right wheels and tires
BMW recommends that you use
only wheel and tire combinations
that BMW has tested and approved for
your particular vehicle. Variations in fac-
tors such as manufacturing tolerances
mean that even wheels and tires with
identical official size ratings could actu-
ally have different dimensions than the
approved units – these differences
could lead to body contact, and with it
the risk of severe accidents. If non-
approved wheels and tires are used,
BMW cannot evaluate their suitability,
and therefore cannot be held liable for
driving safety.<
You can ask your BMW Sports Activity
Vehicle center for the correct wheel/tire
combination.
The correct wheel/tire combination also
affects various systems whose function
would otherwise be impaired, e.g. ABS,
DSC, xDrive.
To maintain good handling and vehicle
response, use only tires of a single
tread configuration from a single manu-
facturer. After a flat tire, always remem-
ber to have the original wheel and tire
combination remounted on the vehicle
as soon as possible.
Recommended tire sizes and makes:
For each tire size, certain tire makes
have been tested by BMW and classi-
fied and approved as safe. You can find
out about them at a specialized store,
preferably your BMW Sports Activity
Vehicle center. Follow any national reg-
ulations, e. g. listed in the vehicle docu-
ments.
The factory-approved radial ply tires are
matched to your vehicle and with
proper use, offer both optimal driving
safety and the desired driving comfort.
Special features of winter tires BMW recommends winter tires for use
in cold winter driving conditions.
Although all-season M+S tires provide
better winter traction than summer
tires, they generally fail to provide the
same levels of cold-weather perfor-
mance as winter tires.
When switching to winter tires, observe
the description under Tire condition,
page144, and Replacing wheels/tires.
Observing speed ratings:
Never exceed the maximum
speed for which the winter tires
are rated. Unprofessional attempts by
laymen to service tires can lead to dam-
age and accidents. Have this work per-
formed by skilled professionals only.
The technicians at your BMW Sports
Activity Vehicle center will be glad to
assist you with the required profes-
sional knowledge and specialized
equipment.<

Replacing wheels/tires Snow chains
*
Storage Store wheels or tires in a cool, dry
place, protecting them against light
whenever possible. Always protect tires
against all contact with oil, grease and
fuels.
Do not exceed the maximum tire infla-
tion pressure indicated on the side wall
of the tire.Only certain snow chains have been
tested by BMW and classified and
approved as safe. Consult your BMW
Sports Activity Vehicle center for
details. BMW recommends only using
these approved, narrow-link snow
chains. Use is only permitted in pairs on
the rear wheels with the following tire
sizes:
X5 4.8is: 255/55 R 18
All other models: 235/65 R 17
Observe the manufacturer's instruc-
tions when installing snow chains.
Do not exceed a maximum speed of
30 mph/50 km/h.
After mounting snow chains, do
not initialize the Flat Tire Monitor.
When you are driving with snow chains,
it can be beneficial to switch off DSC
briefly, refer to page96.<

Lamps and bulbs Changing a tire LEDs light-emitting diodes Light-emitting diodes installed behind
translucent lenses serve as the light
source for many of the controls and
displays in your vehicle. The concept
behind their operation is related to that
employed for lasers.
Do not remove the covers, and
never stare into the unfiltered light
several hours, as irritation of the iris
could result.<
Safety precautions to observe in
the event of a flat and during all
tire changes:
Park the vehicle as far as possible from
passing traffic. Park on a firm, flat, sur-
face. 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
handbrake.
All passengers should be outside the
vehicle and well away from your imme-
diate 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 guidelines and regula-
tions.
Change the wheel only on a level, firm
surface which is not slippery. The vehi-
cle or the jack could slip to the side if
you attempt to raise the vehicle on a
soft or slippery surface such as snow,
ice, tiles, etc.
Position the jack on a firm support sur-
face.
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. To avoid serious or fatal
injury: never lie under the vehicle, and
never start the engine while it is sup-
ported by the jack.<
