Do not use spray starter fluids to start
the engine.
When your battery is discharged you
can used two jumper cables to start
your vehicle with power from the bat-
tery in a second vehicle. 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 high-voltage wiring
and cables on a running engine.
Contact with components carrying high
voltage can be harmful or fatal. Care-
fully observe the following instructions
to avoid personal injury and/or damage
to one or both vehicles.<
1. Ensure that the battery in the sup-
port vehicle is also rated at
12 volts. This information is pro-
vided on the top of the battery
casing
2. Do not disconnect your battery from
your vehicle's electrical system.
Switch off all electrical accessories
in both vehicles
3. Make absolutely certain that there
is no contact between the body-
work of the two vehicles Ð short cir-
cuit hazard
4. Start the engine on the support
vehicle and allow it to run
5. Use one jumper cable (+) to con-
nect the positive terminal of the
battery in the support vehicle with
the auxiliary positive terminal pro-
vided in the engine compartment of
your BMW specifically for jump-
starting. The cover on this auxiliary
terminal is identified by a "+"
symbol, refer to the illustration. Pull
up to open the cover390de690
6. Next, connect one end of the other
jumper cable (Ð) to either the sup-
port vehicle's negative battery ter-
minal or a suitable ground on its
engine or bodywork. Connect the
other end to the negative battery
terminal or a suitable ground on the
vehicle being started. There is a
special nut on the strut dome of
your BMW; refer to the arrow in the
illustration
Always adhere to this sequence
when connecting jumper cables;
failure to observe this procedure can
lead to sparks at the battery terminals
and pose an injury hazard.< 390de146
