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.

Warning triangle*
The warning triangle is stored in the rear trim
panel of the cargo bay.
To take it out, pull the ends of the rubber bands
upward and out of the fasteners.
First-aid kit*
The first-aid kit is located beneath the passen-
ger seat.
Some of the articles in the first-aid kit have a
limited period of use before expiration. For this
reason, check the expiration dates of each of
the items regularly, and replace any with passed
dates.
To open
1.Pull the handle.
2.Swing the cover downward.
To close
Swing the cover back up until it engages.
Jump-starting
If the car's own battery is flat, your BMW's
engine can be started by connecting two
jumper cables to another vehicle's battery. You
can also use the same method to help start
another vehicle. Always use jumper cables with
fully insulated handles on the terminal clamps.
Do not touch any electrically live parts
when the engine is running, or a fatal acci-
dent may occur. Contact with these compo-
nents can cause fatal injury. Carefully observe
the following instructions to avoid personal
injury and/or damage to one or both vehicles.<
Preparations
1.Check whether the battery of the support
vehicle has 12 volts and approximately the
same capacitance in Ah. This information
can be found on the battery.
2.Switch off the engine of the assisting vehi-
cle.
3.Switch off all electrical accessories in both
vehicles.
There must not be any contact between
the bodies of the two vehicles, otherwise
there is a danger of shorting.<
Connecting jumper cables
Connect the jumper cables in the correct
order; otherwise, sparks at the battery
terminals could pose an injury hazard.<
On your BMW, the so-called jump-starting con-
nection in the engine compartment serves as
the battery positive terminal, refer also to the
engine compartment overview on page87. The
symbol + is embossed on the cover.

Giving and receiving assistance
100 1.Open the cover of the BMW jump-starting
connection. Do so by pulling the tab.
2.Attach one terminal clamp of the plus/+
jumper cable to the positive terminal of the
battery or a jump-starting connection of the
vehicle providing assistance.
3.Attach the second terminal clamp of the
plus/+ jumper cable to the positive terminal
of the battery or a jump-starting connection
of the vehicle to be started.
4.Attach one terminal clamp of the minus/–
jumper cable to the negative terminal of the
battery or to an engine or body ground of
the assisting vehicle.
Your BMW is equipped with a special nut,
refer also to the engine compartment over-
view on page87.
5.Attach the second terminal clamp of the
minus/– jumper cable to the negative termi-
nal of the battery or to the engine or body
ground of the vehicle to be started.
Starting the engine
1.Start the engine of the donor vehicle and
allow it to run for a few minutes at slightly
increased idle speed.
2.Start the engine of the other vehicle 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.
3.Let the engines run for a few minutes.
4.Disconnect the jumper cables by reversing
the above connecting sequence.
If necessary, have the battery checked and
recharged.
Never use spray starter fluids to start the
engine.<
Tow-starting, towing away
Using the towing eyelet
The screw-in tow fitting must always be carried
in the car. It can be attached at the front or rear
of your BMW.
It is located in the onboard tool kit, refer to
page93.
Only use the towing eyelet supplied with
the vehicle, and screw it in firmly until it
stops. Use the towing eyelet for towing on
paved roads only. Avoid subjecting the towing
eyelet to lateral loads, e.g. do not lift the vehicle
using the towing eyelet. Otherwise the tow fit-
ting and the vehicle could be damaged.<
