Driving your X5 On bad roads When you are driving on bad roads,
there are a few points which you should
strictly observe — for your own safety,
for that of your passengers, and for the
safety of the vehicle:
Driving on unpaved terrain can
cause damage to the vehicle.<
>Always adapt the driving speed to the
road conditions. The rougher or
steeper the road surface is, the lower
the speed should be
>You can operate your vehicle on
uphill and downhill gradients with a
maximum slope of 50 %. If you want
to drive on uphill or downhill gradi-
ents of this kind, make sure before-
hand that the engine oil and coolant
levels are near the max mark. Refer
to pages 148 and 150.
Use the HDC Hill Descent Control on
steep downhill gradients, refer to
page 96.
It is possible to start off on 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
>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/200 mm with up to four persons
– 7 in/180 mm fully loaded, without
self-leveling suspension
>Only drive through water up to a
maximum depth of 20 in/50 cm and
only at walking speed, making sure
not to stop in the process.
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 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 largest accumulations of
dirt from the body and check the
underbody 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.

General driving notesHot exhaust system
Extreme temperatures occur at
the catalytic converter on this and
every catalyst-equipped vehicle. Do not
remove the heat shields installed adja-
cent to various sections of the exhaust
system, and never apply undercoating
to them. When driving, standing at idle
and while parking take care to avoid
possible contact between a hot exhaust
system and any highly flammable mate-
rials such as hay, leaves, grass etc.
Such contact could lead to a fire, and
with it the risk of serious property dam-
age as well as personal injury.<
Parking vehicle Condensation forms in the air condi-
tioner system during operation, and
then exits under the vehicle. Traces of
condensed water under the vehicle are
thus normal.Brakes
Do not drive with your foot resting
on the brake pedal. Even light but
consistent pedal pressure can lead to
excessively high temperatures, brake
wear and possibly even brake failure.<
Road hazards
If road hazards, obstacles or
curbs are unavoidable, only drive
over them very slowly and carefully, as
otherwise the wheels and suspension
parts, especially on vehicles fitted with
low profile tires, can be damaged.<
For more information on wheels and
tires, refer to page 143.
Before driving into a car washFold in the door mirrors, refer to
page 54, as otherwise they could be
damaged due to the width of the vehi-
cle.Hydroplaning
When driving on wet or slushy
roads, reduce road speed. If you
do not, a wedge of water can form
between tires and road surface. This
state can cause a partial or total loss of
contact with the road surface, of brak-
ing control and of control over the vehi-
cle.<
Driving through water
Do not drive through water on
the road if it is deeper than 20 in/
50 cm, and then only at walking speed
at the most. Otherwise, the vehicle's
engine, the electrical systems and the
transmission may be damaged.<

Safe braking Emergency stopsYou 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.<
Disk 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.<

Information for your safety It is not merely the tire's service life, but
also driving comfort and – to a great
extent – driving safety that depend on
the condition of the tires and the main-
tenance of the specified tire pressure.
Check the tire inflation pressure
regularly, including on the spare
wheel: at least every two weeks and
before beginning a longer trip. If this is
not done, incorrect tire pressures can
cause driving instability and tire dam-
age, ultimately resulting in an accident.
Do not drive with a depressurized, i.e.
flat, tire. A flat tire greatly impairs steer-
ing and braking response, and can lead
to complete loss of control over the
vehicle.<
Checking inflation pressureOnly check tire inflation pressure when
the tires are cold. i.e. after driving a
maximum of 1.25 miles/2 km or when
the vehicle has been parked for at least
2 hours. When tires are warm, the tire
inflation pressure increases.
Inflation pressure for original
equipment tiresYou will find tire inflation pressures on
the inside door pillar.Inflation pressure for other tire
sizesThe table on the next page provides the
correct inflation pressures for tires at
ambient temperature, in psi/kilopascal.
After correcting the inflation pres-
sure(s), always reinitialize the Flat
Tire Monitor, refer to page 100.< 530de225

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, 1g, 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.

OverviewControlsMaintenanceRepairsDataIndex
Tire identification marks Wheel/tire condition TractionThe 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,
hydroplaning, or peak traction charac-
teristics.< 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.
Due to low-profile tires, please
note that wheels, tires and sus-
pension parts are more susceptible to
road hazard and consequential dam-
ages. Unusual vibrations encountered
during normal vehicle operation can
indicate tire failure or some other vehi-
cle defect. This can, for example, be
caused by driving over curbs. This is
also true for irregularities in the vehi-
cle's handling characteristics, such as a
pronounced tendency to pull to the left
or right. Should this occur, respond by
immediately reducing your speed.
Carefully proceed – or have your vehi-
cle 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 condition Replacing wheels/tiresTire treadThe tread depth should not fall below
e in/3 mm.
At tread depths below e 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 k/K in/4 mm, to
ensure continued safety you should
always have such tires replaced.Wear indicators at the tread-groove
base, arrow, are distributed over the
tire's circumference and are marked on
the side of the tire with TWI – Tread
Wear Indicator. These indicators signal
at a tread depth of k/FK in/1.6 mm that
the legally permitted wear limit has
been reached.

Unprofessional attempts by lay-
men to service tires can lead to
damage and accidents.
Have this work performed by skilled
professionals only. The technicians at
your BMW Sports Activity Vehicle cen-
ter will be glad to assist you with the
required professional knowledge and
specialized equipment.<
The correct wheel and tire combination
also affects various systems whose
function would otherwise be impaired,
e.g. ABS, DSC, xDrive.
Have the wheel and tire assemblies bal-
anced every time either a wheel or a tire
is replaced.
BMW does not recommend the
use of retread tires, as otherwise
driving safety may be reduced. Possible
variations in the design and the age –
which could be substantial – of the car-
casses can lead to unusually rapid
wear.<

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
factors such as manufacturing toler-
ances mean that even wheels and tires
with identical official size ratings could
actually 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.<
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.
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,
page 143, 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. 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 page 95.<

Lamps and bulbs Changing a tire Light-emitting diodes LEDs Light-emitting diodes installed behind
translucent lenses serve as the light
source for many of the controls and dis-
plays 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.<
