temperature more quickly.
Hill starta ssist Hill start assist helps you when pulling away
forwards or in reverse on an uphill gradient. It holds the vehicle for a short time after you
have removed your foot from the brake pedal.

Jump-starting
G
Risk of injury
There is a risk of acid burns when jump-starting a vehicle due to the gases which escape from
the battery. Do not lean over the battery while the engine is being jump-started. G
Risk of explosion
Gases escaping from the battery during jump-starting may cause minor explosions. Avoid cre-
ating sparks. Keep naked flames away from the battery, and do not smoke.
Comply with safety precautions when handling batteries. You will find these under "Battery" in
the index.
! Avoid repeated and lengthy starting attempts. Otherwise, non-combusted fuel may dam-
age the catalytic converter 39
and create a risk of fire.
Do not use a rapid-charging device to start the engine.
Make sure the jump leads are not damaged.
Make sure the jump leads are not touching any other metal objects when they are connected
to the battery.
If your vehicle's battery is discharged, the engine can be jump-started from another vehicle
or from a second battery using jump leads.
Observe the following points:
X The battery is not accessible in all vehicles. If the other vehicle's battery is not accessible,
jump-start the vehicle using a second battery or ajump-starting device.
X Only jump-start the vehicle when the engine is cold and the catalyti cconverter system has
cooled down 40
.
X Do not start the engine if the battery is frozen. Let the battery thaw first.
X Jump-starting may only be performed from batteries with a nominal voltage of 12 V.
X Only use jump leads that have a sufficient cross-section and insulated terminal clamps.
X Make sure that the jump leads cannot come into contact with parts, such as the pulley or
the fan. These parts move when the engine is started and while it is running.
X If the battery is fully discharged, leave the battery that is being used to jump-start connected
for a few minutes before attempting to start.T his charges the empty battery a little.
i Jump leads and further information about jump-starting can be obtained from any
Mercedes-Benz Service Centre.
X Make sure that the two vehicles do not touch.
X Apply the parking brake firmly.
X Shift the transmission to position P.
X Switch off all electrical consumers (e.g. radio, blower, etc.).
