Jacking points
The jacking points are located at the positions
indicated in the illustration.
Vehicle battery
Maintenance
The battery is completely maintenance-free.
This means that the original electrolyte will nor-
mally last for the service life of the battery under
moderate climatic conditions. Your BMW Cen-
ter will be happy to advise you if you have any
questions concerning the battery.
Indicator lamp
The indicator lamp lights up:
The battery is no longer being charged.
The alternator drive belt is defective or
there is a malfunction in the charging circuit of
the alternator. Have the system checked as
soon as possible.
If the drive belt is defective, pull over and
switch off the engine immediately to pre-
vent overheating and serious engine damage.
If the onboard supply voltage drops to a very
low level, increased steering effort may also be
necessary.<
Charging the battery
Charge the battery in the vehicle only when the
engine has been switched off. Connections,
refer to Jump-starting on page99.
Battery disposal
After changing a battery, have the used
battery disposed of by your BMW Center or bring it to a recycling point. Maintain the bat-
tery in an upright position for transport and stor-
age. Secure the battery against tilting when
transporting.<
Power loss
After a temporary power loss, the functioning of
some equipment may be limited and require ini-
tialization. Individual settings are also lost and
must be reset:
>Seat memory
The positions must be stored again, refer to
page32.
>Clock must be reset, refer to page47.
Fuses
Do not attempt to repair a burned fuse or
replace it with a fuse having a different
color or amperage rating. To do this could
cause a fire in the vehicle as a result of circuit
overload.<
You will find the fuses and information on their
respective allocation behind the glove compart-
ment.
1.Open the glove compartment.
2.Press the lock on the left, arrow1.
3.Press the lock on the right, arrow2.
4.Swing the glove compartment down.
Spare fuses and plastic tweezers for grasping
the fuses are found in the onboard tool kit; refer
to page93.

Access to the threaded socket
Press out the cover with a screwdriver inserted
in the recess at the top.
Being towed
Make sure that the key is in position 1,
because otherwise the steering lock
could engage and the vehicle could no longer
be steered. There is no power assist while the
engine is off. Therefore, you will need to exert
more force to brake and steer the vehicle.<
Turn on the hazard warning flashers, if required
by national regulations. If the electrical system
has failed, clearly identify the vehicle being
towed, e.g. by placing a sign or a warning trian-
gle in the rear window.
Manual transmission
Gearshift lever in idling position.
Automatic transmission
Selector lever in position N.
Do not exceed a towing speed of 45 mph/
70 km/h or a towing distance of 90 miles/
150 km. Otherwise, the automatic transmission
could be damaged.<
Towing methods
In some countries, it is not permitted to tow the
vehicle with a tow bar or tow rope on public
roads.
Familiarize yourself with the applicable towing
regulations for the country in which you are
driving.
With a tow bar
The towing vehicle must not be lighter
than the towed vehicle, otherwise it may
be impossible to maintain control.<
The towing eyelets of both vehicles should be
on the same side. Should it prove impossible to
avoid mounting the tow bar at an angle, please
observe the following:
>Clearance and maneuvering capability will
be sharply limited during cornering.
>The tow bar will generate lateral forces if it is
attached offset.
Attach the tow bar to the tow fittings only,
as attaching it to other parts of the vehicle
could result in damage.<
With a tow rope
Before the towing vehicle starts to drive off,
make sure that the tow rope is taut.
Use nylon ropes or straps for towing
because they prevent sudden jerking
movements. Attach the tow rope to the tow fit-
tings only, as attaching it to other parts of the
vehicle could result in damage.<
With a tow truck
Have the BMW transported by a tow truck with
a lift sling or a flat bed.
Do not lift the vehicle by the towing eye-
let, or by parts of the body or chassis.
Otherwise damage could result.<
Tow-starting
Do not tow-start vehicles with an auto-
matic transmission. Vehicles with a cata-
lytic converter should only be tow-started if the
