194nBattery
Never allow sparks or open
flame near the battery. Do not
smoke in the vicinity of the
battery. Avoid sparks from electrical
cables or electrical equipment. Turn the
key to position 0 in the steering lock
during the disconnection or connection
of the battery. Never short-circuit the
battery terminals. There is a danger of
injury from powerful sparks.
A highly-explosive gas is
generated when the battery is
charged.
If you happen to get acid in your
eyes, rinse thoroughly for
15 minutes with clear water.
Following that, consult a physician
immediately. If you get acid spray on
your skin or clothing, rinse with plenty
of water. If electrolyte is accidentally
swallowed, consult a physician immedi-
ately.
In order to protect the battery
case from ultraviolet radiation,
do not place it in direct sunlight.
A discharged battery can freeze. Store
the battery in areas where the tempera-
ture remains above freezing.
Charge condition
You can read the charge condition
of the battery with the "Magic Eye"
*
(a hydrometer):
> Green: adequate charge.
> Black: not charged adequately.
The battery must be recharged.
Please contact your BMW center.
> Yellow: replace the battery.
The projected service life of the
battery can only be reached if the
battery is fully-charged at all times.
Check the charge condition of the bat-
tery frequently if the vehicle is used pri-
marily for driving short distances. <

Charging the battery
If the battery is charged in the vehicle:
Do not charge the battery with the
engine running.
Before performing any work on
the electrical system, disconnect
the cable from the negative terminal. If
you do not, short circuits can create the
risk of fire or personal injury. <
If you plan to store the vehicle for more
than four weeks, disconnect the battery
from the vehicle electrical system by
disconnecting the cable at the negative
terminal and then recharge using a suit-
able charging device.
If you intend to store your vehicle for
longer than 12 weeks: remove the bat-
tery, charge it and store it in a cool (but
frost and dust-free) room. Every three
months and before reinstalling the bat-
tery, have it recharged. If it is not
recharged, it will not be serviceable.
Every time the battery is discharged,
especially over extended periods, its
service life is reduced.

202nTowing the vehicle
The towed vehicle should always
be the lighter of the two vehicles.
If this is not the case, it is no longer
possible to control vehicle response. <
Tow-starting
It is not possible to start the engine of
vehicles equipped with an automatic
transmission by towing or pushing.
For instructions on jump starting, refer
to page 200.
Never attempt to use your vehicle to
push another vehicle, since damage to
the energy-absorbing bumpers could
result.
Towing a vehicle with automatic
transmission
1 Place the selector lever in position N.
2 Towing speed: Max. 45 mph (70 km/h).
3 Towing distance: Max. 95 miles (150 km).
4 Leave the ignition key in position 1 to ensure that the brake lamps, turn sig-
nals, horn and windshield wipers re-
main operative, and to prevent the
steering lock detent from engaging.
5 Switch on the hazard warning flash- ers (observe country-specific regula-
tions).
Find some means of identifying the ve-
hicle in tow, for instance, place a sign
or warning triangle in the rear window.
Make sure that the ignition key
remains in position 1 even when
the electrical system has failed to pre-
vent the steering lock from engaging.
The steering and brakes are without
power assist when the engine is off.
This means that increased effort is
required for steering and braking. <
Towing with a commercial
tow truck
> Do not tow with sling-type equip-
ment.
> Use a wheel lift or flat bed carrier.
> Please comply with applicable towing
laws.
Never allow passengers to ride in
a towed vehicle for any reason. <
