Replacing components
100 4.Slowly lower the handle as far as possible,
refer to arrow4.
5.Take out the compact wheel towards the
back.
6.Refit the compact wheel holder in reverse
order.
The defective wheel will not fit into the
compact wheel holder in place of the
compact wheel.<
Preparing wheel change
1.Observe the safety precautions on page99.
2.Secure the vehicle to prevent it from rolling:
Place the wheel chock against the rear sur-
face of the front tire on the side opposite the
side being raised. If the vehicle is parked on
a downward slope, place the wheel chock
securely in front of the tire. If the wheel must
be changed on a surface with a more severe
slope, take additional precautions to secure
the vehicle from rolling.
3.Loosen the lug bolts by a γ 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 section of illustration.
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 turning 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 against dirt and contamina-
tion. Dirt in valve stems is a frequent source
of gradual air loss.<
4.Reinitialize the Flat Tire Monitor, refer to
page49.
Do not initialize the system when driv-
ing with the 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, as otherwise unstable driving condi-
tions may result.<
The driving characteristics change, for example
reduced track stability on braking, extended
braking distance, and altered self-steering
characteristics in the limit range. In conjunction
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 consult you on all questions
concerning the battery.
Warning lamp
The warning lamp lights up. The bat-
tery is no longer being charged. The
alternator V-belt is defective or there is
a malfunction 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 is not running. Use the connections pro-
vided in the engine compartment. For connec-
tions, refer to Jump starting on page104.
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.<

Replacing components

Power failure
Following a temporary power failure, e.g. in the
case of a dead battery, some equipment is sub-
ject to restricted use and must be reinitialized.
Individual settings are also lost and must be
updated again:
>Panorama glass sunroof
The sunroof can only be raised and must be
initialized, refer to page21.
>Power windows
The anti-trapping mechanism must be rein-
itialized, refer to page20.
>Seat and mirror memory
The positions must be stored again, refer to
page26.
>Time
Must be set again, refer to page43.
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.

Jump starting
When your battery is discharged, you can use
two jumper cables to start your vehicle with
power from the battery in a second vehicle. You
can also use the same method to help start
another vehicle. Use only jumper cables with
fully-insulated clamp handles.
To avoid the risk of potentially fatal injury,
always avoid all contact with electrical
components while the engine is running. Care-
fully observe the following instructions to avoid
personal injury and/or damage to one or both
vehicles.<
Preparing
1.Check whether the battery of the other
vehicle has a voltage of 12 Volts and
approximately the same capacitance in Ah.
This information can be found on the bat-
tery.2.Switch off the engine of the vehicle provid-
ing assistance.
3.Switch off any electrical systems and com-
ponents in both vehicles.
Ensure that no contact exists between
the bodywork on the two vehicles, other-
wise there is a danger of short circuits.<
Connecting jumper cables
To avoid personal injury from sparks,
always follow this sequence when con-
necting jumper cables.<
On your BMW, the auxiliary terminal for jump
starting in the engine compartment serves as
the battery positive terminal, refer also to
engine compartment overview on page89.
The symbol + is embossed on the cover.
1.Open the cover of the BMW auxiliary termi-
nal for jump starting, refer to arrow1.
2.Connect one terminal clamp of the posi-
tive/+ jumper cable to the positive terminal
of the battery or an auxiliary terminal of the
vehicle providing starting assistance.
3.Connect the second terminal clamp of the
positive/+ jumper cable to the positive ter-
minal of the battery or to an auxiliary termi-
nal of the vehicle to be started.
Your BMW has a special nut that serves as the
body ground or negative terminal, refer to
arrow2.
4.Attach one end of the jumper cable minus/–
to the negative terminal of the battery or to
an engine or body ground of the vehicle
providing assistance.

Tow-starting and towing
Use tow fitting
The threaded tow fitting is stored in the
onboard tool kit, refer to page95, and must
always remain in the vehicle. It can be screwed
in at the front or rear of the BMW.
To avoid damage to the tow fitting and the
vehicle, observe the following: only use
the tow fitting that comes with the vehicle and
screw it in as far as it will go. Only use the tow
fitting to tow on roads. Avoid lateral loading of
the tow fitting, e.g. do not lift the vehicle by the
tow fitting.<
Access to screw thread
Press out the cover in the front or rear bumper
at the notch at the bottom with a screwdriver.
Being towed
Make sure that the ignition key is in posi-
tion 1, as otherwise the steering lock will
engage, making it impossible to steer the vehi-
cle. There is no power assist with the engine
stopped. It is then necessary to exert increased
effort for braking and steering.<
Switch on the hazard warning flashers depend-
ing on the local regulations. If the electrical sys-
tem fails, mark the vehicle to be towed, e.g. with
a sign or warning triangle in the rear window.
Do not exceed a towing speed of 30 mph/
50 km/h and a towing distance of
95 miles/150 km, as otherwise the drive train
may be damaged.<

Towing methods
In some countries, towing with tow bars or
ropes on public roads is not permitted.
Familiarize yourself with the regulations on tow-
ing in the respective country.
With tow bar
The towing vehicle may not be lighter
than the vehicle to be towed, as otherwise
it will not be possible to control vehicle
response.<

Giving and receiving assistance
106 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 fitting only.
Otherwise damage could result on other
vehicle parts.<
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 on the tow fitting only.
Otherwise damage could result on other vehicle
parts.<
With tow truck
Do not tow the X3 with only the front or
rear axle raised, as otherwise the wheels
could lock and the transfer case could be dam-
aged.<
Only have the X3 transported on a load bed.
Tow-starting
Do not tow-start vehicles with an auto-
matic transmission.
Jump starting, refer to page104.<
Vehicles with a catalytic converter should only
be tow-started when the engine is cold. It is bet-
ter to jump start the engine, refer to page104.
1.Switch on the hazard warning flashers,
comply with country-specific regulations.
2.Turn the ignition key to position 2.
