General driving notesClosing liftgate/tailgate
Operate the vehicle only when the
tailgate and liftgate are completely
closed. Otherwise, exhaust fumes
could enter into the passenger com-
partment.<
However, if special circumstances
should make it absolutely necessary
to operate the vehicle with the liftgate/
tailgate open:
1. Close all windows and the panorama
glass sunroof
2. Increase the air supply for the air
conditioner or automatic climate
control to a high level, refer to
page108 or112.
Hot 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.
Otherwise there is a danger of ignition
and of a fire with the risk of serious inju-
ries and damage. BMW advises against using
mobile radio devices such as por-
table phones inside the vehicle unless
they are directly connected to the
external antenna. Otherwise, it is
impossible to prevent a mutual interfer-
ence of the vehicle electronics with the
portable phone device. Also, there is no
guarantee that the radiation generated
by the transmission will be conveyed
out from the interior of the vehicle.<
When vehicle is parked Condensation forms in the air condi-
tioner system during operation, and
then exits under the vehicle. Traces of
water on the ground are therefore nor-
mal.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 oth-
erwise 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 page144.
Before driving into a car washFold in the exterior mirrors, refer to
page54, 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 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.<

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.<

Coolant Brake fluid4. When necessary, slowly add coolant
until the correct level is reached; do
not overfill
5. Close the cap and tighten snugly
6. Have the cause of the coolant loss
corrected as soon as possible.
Brake fluid level
If the warning lamp lights up or
the message CHECK BRAKE
FLUID appears in the Check
Control: stop immediately.
The brake fluid in the reservoir
has fallen to below the minimum
level.
Add brake fluid The brake fluid reservoir is located
under the microfilter housing trim panel
on the driver's side of the vehicle. For
adding brake fluid or for determining
and correcting the cause of brake fluid
loss, consult your BMW Sports Activity
Vehicle center. Your BMW Sports Activ-
ity Vehicle center is familiar with the
specifications for factory-approved
DOT 4 brake fluids.
Brake fluid loss may result in extended
brake pedal travel. For this situation,
refer to the notes on page140.
Brake fluid is hygroscopic, that is,
it absorbs moisture from the air
over time.
In order to ensure the safety and reli-
ability of the brake system, have the
brake fluid changed every two years by
a BMW Sports Activity Vehicle center.
Refer also to the Service and Warranty
Information Booklet for US models or
the Warranty and Service Guide Book-
let for Canadian models.
Brake fluid is toxic and also damages
vehicle paintwork. Always store these
agents in tightly-closed original con-
tainers kept well away from the reach
of children.
Do not spill the fluid and do not refill the
brake fluid reservoir to beyond the MAX
mark. The brake fluid could ignite upon
contact with hot engine parts and cause
serious burns.<
Always observe all applicable
environmental rules and regula-
tions when disposing of used brake
fluid.<

OBD interface socketThe interface socket for the Onboard
Diagnostic is located on the left of the
driver's side at the bottom of the instru-
ment panel and under a cover. The
cover has the letters OBD on it.
The purpose of the OBD system is to
ensure proper operation of the emission
control system for the vehicle's lifetime.
The system monitors emission-related
components and systems for deteriora-
tion and malfunction.
An illuminated indicator lamp
informs you of the need for ser-
vice, not of the need to stop the
vehicle. However, the systems should
be checked by your BMW Sports Activ-
ity Vehicle center at the earliest possi-
ble opportunity. 530us105
Indication of the above-
described malfunction in Cana-
dian models.
Under certain conditions, the indicator
lamp will blink or flash. This indicates
a rather severe level of engine misfire.
When this occurs, you should reduce
speed and consult the nearest BMW
Sports Activity Vehicle center as soon
as possible. Severe engine misfire over
only a short period of time can seriously
damage emission control components,
especially the catalytic converter.
When the filler cap is not properly
tightened, the OBD system can
detect the vapor leak and the indicator
will light up. If the filler cap is subse-
quently tightened, the indicator lamp
should extinguish within a few days.<
Event Data Recorders Your vehicle may be equipped with one
or more sensing and diagnostic mod-
ules or a recording device capable of
recording or transmitting certain vehicle
data or information. In addition, if you
have a Subscription Service Agree-
ment for the BMW Assist system, cer-
tain vehicle information may be trans-
mitted or recorded in order to provide
such services.

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.<

168n
Changing a wheel Vehicle battery 10. Screw in the remaining lug bolts.
Tighten all the bolts securely in a
diagonal pattern
11. Lower the jack and remove it from
beneath the vehicle
12. Tighten the lug bolts in a diagonal
pattern
13. Check and correct the tire inflation
pressure at the earliest opportunity.
After mounting the spare wheel or
correcting the inflation pressure,
reinitialize the Flat Tire Monitor,
refer to page102.
Protect valve stems and valves from dirt
using screw-on valve stem caps. Dirt in
the valve stems frequently leads to slow
leaks.
The vehicle jack is designed for
changing wheels only. Do not
attempt to raise another vehicle model
with it or to raise any load of any kind.
To do so could cause accidents and
personal injury.
To ensure safety, always have the lug
bolts checked with a calibrated torque
wrench as soon as possible to ensure
that they are tightened to the specified
torque. The tightening torque is
101 ft-lb/140 Nm.<
Store the wheel and the tools in the
order opposite that for removal.
Before removing the support rod,
be sure that the tailgate is held
down firmly. If you fail to do so, it could
retract sharply upward and cause per-
sonal injury and vehicle damage.
After you remove the rod, close the tail-
gate carefully. Continue to hold it firmly
until it is completely closed.<
If light-alloy wheels other than Genuine
BMW light-alloy wheels have been
mounted, it may be necessary to use
different lug bolts for those wheels.
Replace the defective tire as soon as
possible and have the new wheel/tire
balanced. Driving with spare wheel
Do not exceed a speed of
130 mph/210 km/h, otherwise tire
damage could lead to accidents.<
With certain wheel-and-tire com-
binations the size of the spare
wheel differs from that of the other
wheels. To restore the original state,
the normal wheel should be remounted
as soon as possible.<
Battery posts, terminals and
related accessories contain lead
and lead compounds. Wash hands after
handling.<
Battery care The battery is maintenance-free, that is,
the original electrolyte will normally last
for the service life of the battery under
moderate climatic conditions. Your
BMW Sports Activity Vehicle center will
be glad to advise in all matters con-
cerning the battery.Charging battery Only charge the battery in the vehicle
via the terminals in the engine compart-
ment with the engine off. For correct
connections, refer to Jump starting on
page171. Disposal
Following replacement, have old
batteries disposed of by your
BMW Sports Activity Vehicle center or
hand them in to a recycling center.
Maintain the battery in an upright posi-
tion for transport and storage. Always
restrain the battery to prevent it from
tipping over during transport.<
