Help Ð Giving and receiving Warning triangle*

The warning triangle is conveniently stored
in the onboard tool kit mounted on the
inside of the luggage compartment lid.
Comply with legal requirements
requiring you to carry a hazard
warning triangle in the vehicle.< First-aid kit*

You will also find the first-aid kit in the
onboard tool kit's container.
Some of the articles contained in the
first-aid kit have a limited service life.
For this reason, check the expiration dates
of each of the items regularly, and replace
any whose expiration dates have passed.
You can find replacements in any phar-
macy.
Always comply with laws requiring a first-
aid kit to be carried in the vehicle.< Jump-starting Never use spray fluids to start the engine.
When your battery is discharged you can
use two jumper cables to start your vehicle
with power from the battery in a second
vehicle. You can also use the same method
to help start another vehicle. Use only
jumper cables with fully-insulated clamp
handles. To avoid the risk of potentially fatal
injury, always avoid all contact with
electrical components while the engine is
running. Carefully adhere to the following
sequence, both to prevent damage to one
or both vehicles, and to guard against
possible personal injury.<
1.The battery in the support vehicle must
also be rated at 12 volts. This information
can be found on the sticker affixed to the
battery
2.Switch off the support vehicle's engine
and switch off all electrical equipment and
accessories in both vehicles (except the
hazard warning flashers on the support
vehicle)
3.Ensure that no contact exists between
the bodywork on the two vehicles as there
is a danger of short circuits
4.Your BMW is equipped with an auxiliary
terminal specifically designed for jump-
starting located within the engine compart-
ment. The symbol "+" is embossed on the
cover of this auxiliary terminal. Pull the
cover for access to the terminal, see
arrow 1 in the illustration.
Start by connecting one end of a jumper
cable to the positive terminal connected to
the discharged battery, then connect the
other end to the positive terminal of the
battery on the support vehicle
5.Connect the ends of the other jumper
cable to the negative terminals on both
vehicles. Connect the other end to the
negative battery terminal or a suitable

188 ground on the vehicle being started. A
special nut on the strut dome, see arrow 2
in the illustration, serves as the negative
terminal on your BMW
To avoid personal injury from sparks,
always observe this sequence when
connecting the jumper cables.<
6.Start the engine on the support vehicle
and allow it to run for several minutes at a
fast idle
7.Start the engine on the other vehicle in
the usual way. If the first start attempt is not
successful, wait a few minutes before
another attempt in order to allow the
discharged battery to recharge
8.Allow the engines to run for several
minutes before disconnecting the jumper
cables
9.Disconnect the jumper cables by
reversing the connection sequence.
If required, have the battery inspected and
recharged at your BMW center.
Towing
Even if the transmission is in perfect
working order, you should always
remember to disengage the transmission
lockout manually before towing the vehicle.
Failure to observe this precaution could
result in automatic activation of the trans-
mission lockout while the vehicle is being
towed.<
Releasing transmission lockout manually,
refer to page 70.
Tow fittingThe threaded tow fitting is stored in the tool
kit mounted on the inside of the luggage
compartment lid, refer to page 181, and
should always remain in the vehicle. This
fitting, which fits the tow sockets on both
the front and the rear of the vehicle, is
intended exclusively for use in towing the
vehicle on paved roads.
Access to tow sockets Press the arrow symbol to push out the
cover. Front
Rear
Screw the tow fitting in until it
bottoms firmly. If this is not done, the
threads could be damaged.
Never attempt to tow or tie down the
vehicle using suspension components, as
this could lead to damage that might ulti-
mately result in an accident.<
To avoid jerking and the associated
stresses on vehicle components when
towing, always use either a tow bar or a
nylon rope.
Keep the vehicles in line, taking care
to avoid towing at an offset angle, and
make certain that the tow rope connecting
the two vehicles is tight before starting
off.<
Towbars The tow fittings used should be on the
same side on both vehicles.
Should it prove impossible to avoid
mounting the tow bar at an offset angle,
please observe the following:

At a glanceControlsDriving tipsCommunicationsNavigationEntertainmentMobilityReference
189
>Clearance and maneuvering capability
will be strictly limited in corners
>When mounted at an angle, the towbar
will exert lateral forces, tending to push the
vehicle sideways.
Never use a vehicle to tow another
vehicle that is heavier than itself, as
this could lead to a loss of control.< Towing
Do not tow the vehicle by the rear
axle; because the steering detent is
not operational, the wheels could turn to an
extreme angle during towing.<
1.Switch on the ignition to allow operation
of the brake lamps, turn signal indicators,
horn, parking brake and windshield wipers
2.Turn on the hazard warning flashers
where allowed by law
3.Manual release of the transmission
lockout, refer to page 70
4.Maximum towing speed:
maximum 43 mph (70 km/h)
5.Maximum towing distance:
maximum 93 miles (150 km).
If the electrical system in the towed vehicle
has failed, use an alternate means to iden-
tify the vehicle as being towed such as a
sign or warning triangle placed in the rear
window.
The steering and brakes are without
power assistance when the engine is
off. This means that higher levels of effort
will be required to operate the steering and
brakes.<
Tow-starting It is not possible to start the engine by tow-
starting the vehicle.
Jump starting, refer to page 187.
Have the source of the starting difficulties
diagnosed and repaired at your BMW
center.
Towing with a commercial tow truck >Do not tow with sling-type equipment
>Use a wheel lift or flatbed carrier
>Please comply with applicable towing
laws.
Never allow passengers to ride in a
towed vehicle for any reason.<
