Lamps and bulbs
Lamps and bulbs make a significant contribu-
tion to road safety. Therefore, comply fully with
the following instructions during bulb replace-
ment. If you are not familiar with the specified
procedures or they are not described here,
BMW recommends having this work carried out
at your BMW Sports Activity Vehicle Center.
Never touch the glass of new bulbs with
your bare fingers, as even minute
amounts of contamination will burn into the
bulb's surface and reduce its service life. Use a
clean cloth, paper towel, or the like or grasp
bulb by its base.<
A replacement bulb set is available from your
BMW Sports Activity Vehicle Center.
In all work on the electrical system, switch
off the relevant component to prevent
short circuits. To avoid possible injury or equip-
ment damage when replacing bulbs, follow any
instructions provided by the bulb manufac-
turer.<
When maintaining the headlamps, please follow
the instructions in the separate Caring for your
vehicle brochure.

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.
Compact wheel
The compact wheel is located under the cargo
area on the undercarriage of the vehicle.
Removing compact wheel
1.Unscrew bolt, refer to arrow1.
2.Fold up lifting handle, refer to arrow2.
3.Turn the handle to the left as far as possible,
refer to arrow3.
Turning the handle releases the com-
pact wheel. Its weight of approx.
18 lbs./8 kg is then entirely supported by
the handle.<4.Slowly lower the handle as far as possible,
refer to arrow4.
5.Pull the compact wheel to the rear so that it
is still securely resting in its compact wheel
receptacle.
6.If need be, turn the wheel in the compact
wheel receptacle so that the attachment of
the retaining strap to the rim points toward
the rear.
7.Rotate the clamp by 180°, refer to arrows 1,
and unhook the retaining strap from the
clamp, refer to arrow 2.
8.Take out the compact wheel toward the
back.
9.Fasten the retaining strap to the compact
wheel receptacle and resecure the compact
wheel receptacle by reversing the above
steps.
The width of the defective wheel prevents
it from fitting into the compact wheel
receptacle in place of the compact wheel
itself.<

Inserting compact wheel
The compact wheel is reinserted in the reverse
sequence of its removal.
When attaching the retaining strap to the
compact wheel, make sure the belt is
threaded through 2 rim openings, with one
unoccupied hole between them; otherwise, the
compact wheel could come loose in an acci-
dent.<
Preparing wheel change
1.Observe the safety precautions on
page109.
2.Secure the vehicle to prevent it from rolling:
Place the wheel chock behind the front
wheel on the side of the vehicle opposite
the side being raised. If the vehicle is parked
on a downward slope, place the wheel
chock securely in front of this wheel. If the
road surface is steeply inclined, take addi-
tional preventive steps to stop the vehicle
from rolling.
3.Loosen the wheel lugs by a half turn.
Jacking up vehicle
1.Position the vehicle jack at the jacking point
closest to the wheel so that the entire sur-
face of the jack base perpendicularly con-
tacts the ground under the jacking point.
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.<2.Guide the jack head into the rectangular
recess of the jacking point when cranking
up, refer to drawing inset.
3.Jack the vehicle up until the wheel you are
changing is raised from the ground.
Mounting a wheel
1.Unscrew the lug bolts and remove the
wheel.
2.Remove accumulations of mud or dirt from
the mounting surfaces of the wheel and
hub. Clean the lug bolts.
3.Position the new wheel or compact wheel.
Secure the wheel by screwing at least two
lug bolts into opposite bolt holes. When you
mount wheels other than Genuine BMW
light-alloy wheels, different lug bolts may
also be required.
4.Screw in the remaining lug bolts. Tighten all
the bolts securely in a diagonal pattern.
5.Lower the jack and remove it from beneath
the vehicle.
After mounting
1.Tighten the lug bolts in a diagonal pattern.
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 speci-
fied torque. The tightening torque is
101 lb ft/140 Nm.<
2.Stow the defective wheel in the cargo area.
3.Check and correct the tire inflation pressure
at the earliest opportunity.

Protect valve stems with valve stem
seal caps from dirt and contamina-
tion. Dirt in valve stems is a frequent source
of gradual air loss.<
4.Reinitialize the Flat Tire Monitor
* or reset
the Tire Pressure Monitor
*, refer to
pages53, 54.
Do not initialize the Flat Tire Monitor
when driving with a compact wheel.<
5.Replace the defective tire as soon as possi-
ble and have the new wheel/tire balanced.
Driving with compact wheel
Drive reservedly and do not exceed a speed of
50 mph/80 km/h.
Mounting the compact wheel can change the
driving characteristics. For example, it can
reduce tracking stability during braking, extend
braking distances, and alter self-steering char-
acteristics in the limit range. With winter tires,
these characteristics are more pronounced.
Only one compact wheel may be
mounted. You should re-equip with
wheels and tires of the original size as soon as
possible.<
Vehicle battery
Maintenance
The battery is 100 % maintenance-free, i.e., the
electrolyte will last for the life of the battery
when the vehicle is operated in a temperate cli-
mate. Your BMW Sports Activity Vehicle Center
will be happy to advise you on all questions con-
cerning the battery.
Warning lamp
The warning lamp lights up. The battery
is no longer being charged. The alterna-
tor V-belt is defective or there is a mal-
function in the charge current circuit of the
alternator. Have the system checked immedi-
ately.Do not continue driving if the V-belt is
defective. The engine could be damaged
due to overheating.
Moreover, an increased amount of force is
required for steering if there is a sharp drop in
the onboard supply voltage.<
Charging battery
Charge the battery in the vehicle only when the
engine has been switched off. For connections,
refer to Jump starting on page114.
Disposal
Have old batteries disposed of following
replacement at your BMW Sports Activity
Vehicle Center or bring them to a collection
point. Maintain the battery in an upright position
for transport and storage. Always secure the
battery to prevent it from tipping over during
transport.<
Power failure
After a temporary power supply interruption,
some equipment is subject to limited use and
must be reinitialized. Individual settings are also
lost and must be updated again:
>Panorama glass sunroof
It may be only possible to raise the sunroof.
The system must be initialized, refer to
page24.
>Power windows
The pinch protection system must be reini-
tialized, refer to page23.
>Seat and mirror memory
The positions must be stored again, refer to
page30.
>Time
Must be set again, refer to page46.

Towing methods
To avoid damage, do not lift the vehicle by
the tow fitting or body and suspension
parts.<
In some countries, towing with tow bars or
ropes on public roads is not permitted. Familiar-
ize yourself with the regulations on towing in the
specific country.
With tow bar
The towing vehicle must not be lighter
than the vehicle to be towed; otherwise,
it will not be possible to safely control vehicle
response.<
The tow fittings used should be on the same
side on both vehicles. Should it prove impossi-
ble to avoid mounting the tow bar at an offset
angle, please observe the following:
>Clearance and maneuvering capability will
be strictly limited in corners.
>When mounted at an angle, the tow bar will
exert lateral forces, tending to push the
vehicle sideways.
Secure the tow bar to the tow fittings
only. Otherwise, other vehicle parts could
be damaged.<
With tow-rope
When starting off in the towing vehicle, make
sure that the tow-rope is taut.
To avoid jerking and the associated
stresses on vehicle components when
towing, always use nylon ropes or nylon straps.
Secure the tow rope to the tow fittings only.
Otherwise, other vehicle parts could be dam-
aged.<
With tow truck
Do not tow the X3 with only the front or
rear axle raised; otherwise, the wheels
could lock and the transfer case could be dam-
aged. Tow starting
If possible, do not tow start the vehicle; jump
start the engine instead, refer to page114.
Vehicles equipped with catalytic convertors
should only be tow started when the engine is
cold. It is not possible to tow start an engine
equipped with an automatic transmission.
1.Switch on hazard warning flashers, comply
with local regulations.
2.Switch on ignition, refer to page37.
3.Shift into 3rd gear.
4.Have the vehicle tow-started with the clutch
depressed and slowly release the clutch.
After the engine starts, immediately
depress the clutch again.
5.Stop at a suitable location, remove the tow
bar or rope and switch off the hazard warn-
ing flashers.
6.Have the vehicle checked.
Do not activate the HDC Hill Descent
Control during tow starting, refer to
page51.<
