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
101lbft/140Nm.<
2.Stow the defective wheel in the cargo area.
3.Check and correct the tire inflation pressure
at the earliest opportunity.
Protect valve stems and 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
pages51, 52.
Do not initialize the Flat Tire Monitor
when driving with a compact wheel.<
5.Replace the damaged tire with a new one as
soon as possible and have the new wheel
balanced.
Driving with compact wheel
Drive reservedly and do not exceed a
speed of 50 mph/80 km/h. Do not deacti-
vate DSC; otherwise, unstable driving condi-
tions may result.<
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 quickly 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.

Replacing components
106 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 page108.
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
page23.
>Power windows
The pinch protection system must be reini-
tialized, refer to page22.
>Seat and mirror memory
The positions must be stored again, refer to
page29.
>Time
Must be set again, refer to page44.
Fuses
Never attempt to repair a blown fuse, and
do not replace a defective fuse with a sub-
stitute of another color or amperage rating, as
this could lead to a circuit overload, ultimately
resulting in a fire in the vehicle.<
Open the glove compartment and turn the two
quick-release fasteners to the left, refer to
arrows.
Spare fuses, plastic tweezers, and information
about fuse allocation are stored with the fuses.

Giving and receiving assistance
110
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.<
Have the X3 transported only on a flat bed.To avoid damage, do not lift the vehicle
from the tow fitting or body and suspen-
sion parts.<
Tow starting
If possible, do not tow start the vehicle; jump
start the engine instead, refer to page108.
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 page36.
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
page49.<
