If you treat the engine with sufficient care
from the very start, you wil lberewarded with
excellent performance for the remainder of
the engine' slife.
R Drive at varying vehicle speeds and engine
speeds for the first 1,500 km.
R Avoid overstraining the vehicle during this
period, e.g. driving at ful lthrottle.
R Change gea ringood time, before the rev
counter needle is Ôof the way to the red
area of the rev counter.
R Do not shift down agear manually in order
to brake.
R Try to avoid depressing the accelerator

R in vehicles with automatic transmission,
the transmission is locked in position P
after disconnecting the battery. The vehi-
cle is secured against rolling away. You
can then no longer move the vehicle.
The battery and the cover of the positive
terminal clamp must be fitted securely dur-
ing operation.
In order for the battery to achieve the maxi-
mum possibles ervice life, it must always be
sufficiently charged.
The vehicle battery, like other batteries, can
discharge over time if you do not use the
vehicle. In such cases, have the battery dis-
connected at aqualified specialist workshop.
You can also charge the battery with a
charger recommended by Mercedes-Benz.
For more information, please contact aquali-
fied specialist workshop.
Have the battery charge checked more fre-
quently if you use the vehicle mainly for short
trips or if you leave it standing idle for a
lengthy period. Consult aqualified specialist
workshop if you wish to leave your vehicle
parked up for along period of time.
i When you park the vehicle, remove the
key if you do not require any electrical con-
sumers. The vehicle will then use very little
energy, thus conserving battery power.
i After an interruption of the power supply,
e.g. the battery was discharged, you have
to:
R set the clock. Information on setting the
clock can be found in the separate oper-
ating instructions.
On vehicles with COMAND Online and a
navigation system, the clock is set auto-
matically.
R reset the function for folding the exterior
mirrors in/out automatically, by folding
the mirrors out once (Y page 106). Charging the battery
G
WARNING
Only charge the battery in awell-ventilated
area. As the battery is being charged, gases
can escape and generate minor explosions.
This could injure you and other persons or
cause damage to the paintwork or acid cor-
rosion on the vehicle.
You can obtain information on battery charg-
ers which allow the battery to be charged
while still installed from aqualified specialist
workshop. G
WARNING
There is arisk of acid burns during the charg-
ing process due to the gases which escape
from the battery. Do not lean over the battery
during the charging process. G
WARNING
Battery acid is caustic. Avoid contact with the
skin, eyes or clothing.
! Only charge the installed battery with a
battery charger which has been tested and
approved by Mercedes-Benz.T hese battery
chargers allow the battery to be charged
while still installed in the vehicle.
! Only use battery chargers with amaxi-
mum charging voltage of 14.8 V.
! Only charge the battery using the jump-
start connection point.
The jump-starting connection point is in the
engine compartment( Ypage 319).
Read the battery charger's operating instruc-
tions before charging the battery.
X Open the bonnet (Y page 296).
X Connect the battery charger to the positive
terminal and earth point in the same order
as when connecting the donor battery in
the jump-starting procedure
(Y page 319). 318

Jump-starting
G
WARNING
There is arisk of acid burns when jump-starting avehicle due to the gases which escape from
the battery. Do not lean over the battery while the engine is being jump-started. G
WARNING
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 the important safety precautions when handling batteries. You will find these under
"Battery (vehicle) -important safety notes" in the index. G
WARNING
Non-combusted fuel can collect in the exhaust system and ignite. There is arisk of fire. Avoid
repeated and lengthy starting attempts.
! Vehicles with apetrol engine: avoid repeated and length ystarting attempts. Otherwise,
th en on-combusted fuel may damage th ecatalytic converter.
Do not use arapid chargin gdevic etos tart th evehicle. If your vehicle's batter yisdischarged,
the engin ecan be jump-started from another vehicle or from asecon dbatter yusing jump
leads. Observe the following points:
R The batter yisnot accessible in all vehicles. If the other vehicle's batter yisnot accessible,
jump-start the vehicle using asecond battery or ajump-starting device.
R vehicles with apetrol engine: onlyjump-star tthe vehicle when the engine and exhaust
system are cold.
R do not start the engine if the battery is frozen.L et the battery thaw first.
R jump-starting may only be performed from batteries with anominal voltage of 12 V.
R only use jump leads that have asufficient cross-section and insulated terminal clamps.
R if the battery is fully discharged, leave the battery that is being used to jump-start connected
for afew minutes before attempting to start. This charges the empty battery alittle.
R make sure that the two vehicles do not touch.
Make sure that:
R The jump leads are not damaged.
R Non-insulated parts of the terminal clamps do not come into contact with other metal parts
while the jump leads are connected to the battery.
R the jump leads cannot come into contact with parts such as the V-belt pulleyort he fan.
These parts move when the engine is started and while it is running.
X Firmly depress the parking brake.
X Shift the transmission to position P.
X Switch off all electrical consumers (e.g. radio, blower, etc.).
X Open the bonnet (Y page 296).
