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.

2.Press button1 for at least 2 seconds.
The LED in the button lights up. As soon as a
telephone connection to the BMW Assist
response center has been set up, the LED
flashes.

vehicle until the connection has been estab-
lished. You will then be able to provide a
detailed description of the situation.If your vehicle is equipped with an activated
BMW Assist and the current location of the
vehicle can be determined, this location is
transmitted to the BMW Assist response cen-
ter.
If the LED is flashing but you cannot hear the
emergency response center, you may still be
heard by the emergency response center.
If certain requirements are met, an emergency
call is automatically initiated after a serious
accident. The automatic emergency call will not
be hindered by pressing the button.
For technical reasons, the emergency call
cannot be guaranteed under unfavorable
conditions.<
Roadside Assistance
The BMW Group's Roadside Assistance ser-
vice is there to assist you around the clock in
the event of a breakdown, including on week-
ends and public holidays.
The phone numbers of the Roadside Assis-
tance in your home country can be found in the
Contact brochure.

2.Press button2 for at least 2 seconds.
The LED in the button lights up. As soon as a
telephone connection to the Roadside Assis-
tance has been set up, the LED flashes.
Depending on the country you are in, your vehi-
cle's current location will also be transmitted if
your vehicle is equipped with an activated BMW
Assist function.

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.<

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
