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 page

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
page

Clock must be reset, refer to page

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.

Open the glove compartment.

Press the lock on the left, arrow

Press the lock on the right, arrow

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

reason, check the expiration dates of each of
the items regularly, and replace any with passed
dates.

To open

Pull the handle.

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

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.

Switch off the engine of the assisting vehi-
cle.

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 page

. The

symbol + is embossed on the cover.

Open the cover of the BMW jump-starting
connection. Do so by pulling the tab.

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.

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.

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 page

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

Start the engine of the donor vehicle and
allow it to run for a few minutes at slightly
increased idle speed.

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.

Let the engines run for a few minutes.

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
page

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

engine is cold. It is recommended to start the
engine using jumper cables, refer to page

Switch on hazard warning flashers, comply
with local regulations.

Turn the key to position 2.

Shift into 3rd gear.

Have the vehicle tow-started with the clutch
depressed and slowly release the clutch.
After the engine starts, immediately
depress the clutch again.

Stop at a suitable location, remove the tow
bar or rope and switch off the hazard warn-
ing flashers.

Have the vehicle checked.
