Jump-start connection point
:
Earth point (negative terminal)
; Positive terminal (under the cover) Reconnecting the battery
! Always disconnect the battery in
the order described below. Never swap the
battery terminals. You may otherwise dam-
age the vehicle electronics.
X Switch off all electrical consumers (e.g.
radio, blower, etc.).
X Connect the positive terminal clamp and
secure the cover.
X Connect the negative terminal clamp.
X Connect the breather hose.
i If the battery power supply has been inter-
rupted (e.g. if it has been reconnected), you
must carry out the following tasks:
R set the time (Y page 104).
On vehicles with COMAND and a naviga-
tion system*, the clock is set automati-
cally.
R reset the sliding/tilting sun-
roof* (Y page 151).
R reset the function for folding the exterior
mirrors in/out automatically* by folding
the mirrors out once (Y page 73)
R reset the side windows ( Ypage 86). Jump-starting
If your vehicle's battery is discharged, the
engine can be jump-started from another
vehicle or from an external battery using jump
leads.
Observe the following points:
R you may only jump-start when the engine
and catalytic converter are cold.
R do not start the engine if the battery is fro-
zen. Let the battery thaw first.
R jump-starting may only be performed from
batteries with a nominal voltage of 12 V.
R only use jump leads which have a sufficient
cross-section and insulated terminal
clamps.
i Jump leads and further information about
jump-starting can be obtained from any
Mercedes-Benz Service Centre.
! Avoid repeated and lengthy starting
attempts.
Do not use a rapid-charging device to start
the engine. G
Risk of injury
There is a risk of acid burns when jump-start-
ing 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
creating sparks. Keep naked flames away
from the battery, and do not smoke.
Comply with safety precautions and take pro-
tective measures when handling batteries.
You will find these under "Battery" in the
index.
X Make sure that the two vehicles do not
touch.
X Depress the parking brake firmly. 276
