Lamps and bulbs The lamps and bulbs are essential fac-
tors contributing to the safety of your
vehicle. For this reason, follow the in-
structions below carefully when replac-
ing a bulb. If you are not familiar with
any of the procedures, consult your au-
thorized BMW center.
Do not touch the glass portion of a
new bulb with your bare hands
since even small amounts of impurities
burn into the surface and reduce the
service life of the bulb. Use a clean
cloth, paper napkin, or a similar mate-
rial, or hold the bulb by its metallic
base.<
A replacement bulb set is available from
your BMW center.
Whenever working on the electri-
cal system, switch off the electri-
cal accessory you are working on or
disconnect the cable from the negative
terminal of the battery. Failure to do this
could result in short circuits.
To prevent injuries and damage, com-
ply with any instructions provided by
the bulb manufacturer.<
The illustration shows the right-hand
engine compartment.
For checking and adjusting head-
lamp aim, please contact your
BMW center.< 1 Low beams H7 bulb, 55 watts
The bulb is pressurized. There-
fore, wear safety glasses and pro-
tective gloves. Failure to comply with
this precaution could lead to injury if the
bulb is accidentally damaged during re-
placement.<
1 Turn the bulb holder to the left (arrow)
and remove.
2 Remove and replace the bulb. 530us107
2 High beams HB3 bulb, 60 watts
The bulb is pressurized. There-
fore, wear safety glasses and pro-
tective gloves. Failure to comply with
this precaution could lead to injury if the
bulb is accidentally damaged during re-
placement.<
1 Turn the bulb holder to the left and
remove.
2 Disconnect the plug.
3 Plug the new bulb holder with bulb
into the plug connector. Be sure that
it is securely engaged.
4 Install in the opposite order.
When cleaning the headlamps,
please observe the following:
>Do not clean by wiping with a dry
cloth (scratches). Never use abra-
sives 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.<

Changing a wheel
Safety measures in the event of a
ßat tire or wheel change:
Stop the vehicle as far as possible from
passing trafÞc. Park on a Þrm, ßat, sur-
face. Switch on the hazard ßashers.
Turn the steering wheel to the straight-
ahead position, remove the key and en-
gage the steering lock. Select ÒParkÒ po-
sition and engage the parking brake. All
passengers should be outside the vehi-
cle and well away from your immediate
working area (behind a guardrail, for in-
stance). If a warning triangle or portable
hazard warning lamp is available, set it
up on the roadside at an appropriate
distance from the rear of the vehicle.
Comply with all safety guidelines and
regulations. Change the wheel only on a
level, Þrm surface which is not slippery.
Avoid jacking the vehicle up on a soft or
slippery surface (snow, ice, very smooth
surfaces, etc.), since it could slide side-
ways. Position the jack on a Þrm support
surface. 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. Do not lie under
the vehicle or start the engine when the
vehicle is supported by the jack. Failure
to comply with this creates a risk of fatal
injury.<
What you will need In order to avoid rattling noises later,
note the position of the tools when you
remove them and return them to their
original position when you are through
using them.
>Two wedges (wheel chocks)
Open the liftgate and tailgate.
In the cargo area, fold up the floor
cover or pull-out cargo floor (refer to
page 110 or 111).
Take out the wedges (arrow) next to
the spare wheel. 530us117

Battery Charging the battery Charge the battery in the vehicle only
when the engine is not running. Use the
connections provided in the engine
compartment (for correct connections,
refer to "Jump-starting" on page 170).
The service life specified for the
battery can be achieved only if it
is always kept adequately charged.
Have the charge condition of the bat-
tery checked frequently if the vehicle
is used primarily for driving short
distances.<
Before performing any work on
the electrical system, disconnect
the cable from the negative terminal. If
you do not, short circuits can create the
risk of fire or personal injury.<
If you plan to park the vehicle longer
than 4 weeks, have the battery discon-
nected from the vehicle's electrical
system by disconnecting the cable from
the negative terminal. Then have the
battery charged with an appropriate
battery charger.
If the vehicle will not be driven for a
period longer than 12 weeks, have the
battery removed, charged and store it
in a clean and cool (frost-free) area.
Recharge the battery at least every
three months during storage. Also,
recharge the battery before it is in-
stalled. If you fail to do so, it will not be
serviceable. Every time the battery is
discharged, especially over extended
periods, its service life is reduced. Do not disconnect the battery
when the engine is running. If
you do so, the ensuing voltage surge
will damage the vehicle's onboard elec-
tronics.
Do not make any modifications in the
wires to the positive terminal. If you do
so, the protective function of the safety
battery terminal is no longer ensured.
Repair and disposal must be performed
by trained technicians only.<
Return used batteries to a recy-
cling point or your authorized
BMW center. Maintain the battery in an
upright position for transport and stor-
age. Secure the battery against tilting in
transit.<

170n
Do not use spray starter fluids to start
the engine.
If the battery is discharged, the engine
can be started with the use of two
jumper cables and the battery of an-
other vehicle. Always use jumper ca-
bles with fully insulated handles on the
terminal clamps.
Do not touch the parts conducting
current while the engine is run-
ning. Failure to comply with this creates
a risk of fatal injury.<
Carefully comply with the following in-
structions to avoid personal injury and
damage to one or both vehicles:
1 Be sure that the battery on the sup-
port vehicle is also rated at 12 volts,
and that the capacities of the two
batteries (Ah) are roughly comparable
(printed on casing).
2 Leave your battery connected to the
vehicle's electrical system.
3 Make sure that there is no contact
between the bodywork of the two
vehicles Ð this creates a risk of short
circuits.
4 Start by connecting the jumper cable
from the positive terminal of the sup-
port vehicle to the positive terminal
connector located in your BMW's en-
gine compartment The cover of the
auxiliary terminal for jump starting is
marked with a "+" sign (refer to the il-
lustration). To remove the cover, tip
up the cap (arrow). 530us126
5 Then connect the negative terminals.
Attach the cable to either the support
vehicle's negative battery terminal (-),
or to a suitable ground on its engine
or bodywork. Then connect the other
end of the cable to a ground on the
engine or on the bodywork of the ve-
hicle that is to be started. There is a
special nut for this on the left side
panel of your BMW. Refer to the ar-
row in the illustration.
Follow the same sequence for
connecting the jumper cables
when helping other vehicles. If you do
not, there is the risk of injury if sparks
generate at the battery.< 530us127

Jump-starting Towing the vehicle 6 Start the engine on the support
vehicle and let it run.
7 Start the engine on the vehicle need-
ing the jump-start, and allow it to run
as usual. If the first start attempt is
not successful, wait a few minutes
before another attempt in order to
allow the discharged battery to
recharge.
8 Before disconnecting the jumper ca-
bles from your BMW, turn on the rear
window defroster and set the blower
to the highest speed; allow the en-
gine to run approx. 10 seconds. This
will prevent a voltage surge from the
voltage regulator to the electrical ac-
cessories.
9 Then disconnect the jumper cables in
reverse sequence.
Have the battery recharged if neces-
sary.
Tow fitting The screw-in tow fitting is stored be-
neath the cargo area floor. Carry it with
you at all times. This fitting is designed
for installation in the tow sockets lo-
cated at the front and rear of the vehi-
cle, and is intended for towing on
paved road surfaces only.
It should not be used to pull a vehicle
out of deep snow, mud, sand, etc.
Always observe all applicable towing
laws and regulations. Access to tow sockets Front:
Use a screwdriver on the left or right
side (arrows) to press the cover out . 530us128
Rear: pull the cover off.
Screw the tow fittings in until they
are tight. If you do not, the threads
could be damaged.
Do not tow the vehicle by any compo-
nents of the running gear, or lash them
down in any way. If you do so, the com-
ponents could be damaged, leading to
possible accidents.<
Use only a nylon towing strap to tow
the vehicle, since the inherent resil-
ience of this material helps protect both
vehicles from sudden jerking move-
ments.
Avoid "off-center" towing. Be sure
that the tow rope is pulled tightly
when the towing vehicle begins to
move.< 530us129

172n
Towing the vehicle
The towed vehicle should always
be the lighter of the two vehicles.
If this is not the case, it is no longer
possible to control vehicle response.<
Tow-starting It is not possible to start the engine of a
vehicle equipped with automatic trans-
mission by towing or pushing.
For instructions on jump starting: refer
to page 170.
Never attempt to use your vehicle to
push another car. If you do so, damage
to the energy-absorbing bumpers could
result.
Towing 1 Place the selector lever in "Neutral".
2 Towing speed:
Max. 45 mph (70 km/h).
3 Towing distance:
Max. 95 miles (150 km).
4 Leave the ignition key at position 1 to
ensure that the brake lamps, turn sig-
nals, horn and windshield wipers re-
main operative, and to prevent the
steering lock detent from engaging.
5 Switch on the hazard-warning system
(comply with country-specific regula-
tions).
Find some means of identifying the ve-
hicle in tow, for instance, place a sign
or warning triangle in the rear window.
Make sure that the ignition key re-
mains in position 1 even when the
electrical system has failed. This will
prevent the steering lock from engag-
ing. The steering and brakes are with-
out power assist when the engine is not
running. This means that increased ef-
fort is required for steering and brak-
ing.<
Towing with a commercial tow
truck >Do not tow with sling-type equip-
ment.
>Use a wheel lift or flat bed carrier.
>Please comply with applicable towing
laws.
Never allow passengers to ride in
a towed vehicle for any reason.< 530us138

2 Switch off the engine.
3 Towing speed:
Maximum 30 mph (50 km/h).
4 Towing distance:
Maximum 95 miles (150 km).
Remove the rear driveshaft for
longer towing distances with the
front axle lifted; remove the front drive-
shaft for towing over longer distances
with the rear axle lifted. Failure to com-
ply with this will result in damage to the
transfer box.<

The transmission of power to the four
drive wheels is provided permanently
through a transfer box. The distribution
of torque between the front and rear
axles is 38% to 62%.
Traditional differential locks at the front
and rear axles and in the transfer box
are not required. Their function is taken
over by automatic braking intervention
at all four wheels. These traction inter-
ventions are governed by Automatic
Differential Brake (ADB), a sub-function
of DSC.
If a wheel tends to slip, it is braked
automatically by ADB until it once again
gains traction, and drive force can be
transmitted to that wheel. In addition,
the drive force is distributed to the
remaining wheels during this system
530us133
intervention. Engine output is also re-
duced if necessary.
When the DSC is deactivated, the ADB
traction intervention is set for the maxi-
mum drive force. However, the engine
intervention and the stability controls
are no longer available. For this reason,
DSC should only be deactivated in the
exceptional circumstances described
on page 83.
The BMW X5 is a vehicle for all types of
roads. The permanent four-wheel drive
provides a significant degree of vehicle
stability and tractive power under all
road conditions. It assists in critical sit-
uations such as driving in extreme win-
ter conditions or on bad roads. Precision sensors monitor the wheel
speeds, the steering angle, lateral
acceleration, brake pressure and the
movement of the vehicle around its
vertical axis.
If differences in wheel speeds occur,
the system recognizes the danger of
wheelspin and reduces the engine's
drive torque. If necessary, the system
also responds with additional braking
intervention at all four wheels.
In addition, DSC permanently monitors
the vehicle's current operating condi-
tion and compares it with an ideal con-
dition that is calculated from the sensor
signals. If discrepancies from this ideal
condition (understeering or oversteer-
ing, for example) occur, DSC stabilizes
the vehicle in fractions of a second by
reducing engine power output and with
the assistance of braking intervention at
individual wheels. Dangerous skids are
thus prevented from the very beginning.
You may need some time to become
accustomed to this system intervention.
However, it provides optimum drive
force and vehicle stability.
The braking intervention may be ac-
companied by certain sounds specific
to the system.
