for further information and availability. Read the
battery charger's operating instructions before
charging the battery.
Do not charge a battery which has been
removed at low temperatures with a battery
charger. Allow the battery to warm up gently
first, if necessary. Otherwise, the service life can
be shortened and the starting characteristics
impaired, especially at low temperatures.
Replacing the 12 V battery
Observe the notes on the 12 V battery
(Y page 254).
Mercedes-Benz recommends that you have the
12 V battery replaced at a qualified specialist
workshop, e.g. at an authorized Mercedes-Benz
Center.
If you want to replace the battery yourself,
observe the following notes:
R
Always replace a defective battery with a bat-
tery which meets the specific requirements of
the vehicle.
The vehicle is equipped with an AGM (Absorb-
ent Glass Mat) technology battery or a lith-
ium-ion battery. Full vehicle functionality is
only guaranteed with an AGM or lithium-ion
battery. For safety reasons, Mercedes-Benz
recommends that you only use batteries
which have been tested and approved for your
vehicle by Mercedes-Benz.
R
Use detachable parts such as breather hoses,
angled connecting pieces or terminal covers
from the battery which is to be replaced.
R
Make sure that the vent hose is always con-
nected to the original opening on the battery
side.
Install any existing or supplied stop plugs.
Otherwise, gases or battery acid could
escape.
R
Make sure that the detachable parts are con-
nected again in the same way.
Jump-starting
X
For the jump-starting procedure, use only the jump-starting connection point in the engine com-
partment, consisting of a positive terminal and a ground point.
!
Avoid repeated and lengthy starting attempts. Otherwise, the catalytic converter could be
damaged by the non-combusted fuel.
X
Do not start the vehicle using a rapid charging device.
If your vehicle's battery is discharged, the engine can be jump-started from another vehicle or
from a donor battery using jumper cables.
The battery is not accessible in all vehicles. If the other vehicle's battery is not accessible, jump-start
the vehicle using a donor battery or a jump-starting device.
Observe the following during the jump-starting procedure:
R
the jumper cables must not come into contact with parts that can move when the engine is
running, such as the V-belt pulley or the fan.
R
non-insulated parts of the terminal clamps must not come into contact with other metal parts
while the jumper cables are connected to the battery and the jump-starting connection point.
R
only use jumper cables that are not damaged and have a sufficient cross-section and insulated
terminal clamps.
R
jump-starting may be performed only using batteries with a nominal voltage of 12 V.
R
you may only jump-start the vehicle when the engine and exhaust system are cold.
R
the vehicles must not touch each other.
R
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. This charges the battery slightly.
