Checking the coolant level G
WARNING
In order to avoid potentially serious burns:
R use extreme caution when opening the
hood if there are any signs of steam or
coolan tleaking from the cooling system, or
if the coolant temperature display indicates
that the coolant is overheated.
R do not remove the pressure cap on the
coolant tank if the coolant temperature is
above 104 ‡ (40 †). Allow the engine to
cool down before removing the cap. The
coolant tank contains hot fluid and is under
pressure.
R using a cloth, slowly turn the cap
approximately Öturn to relieve excess
pressure. If you open the cap immediately,
scalding hot fluid and steam will be blown
out under pressure.
R do not spill antifreeze on hot engine parts.
Antifreeze contains ethylene glycol which
may burn if it comes into contact with hot
engine parts.
! The coolant may only be checked and
corrected when the engine is cool (coolant
temperature below 104 ‡ (40 †).
Checking the coolant when the coolant
temperature is above 104 ‡ (40 †) may
result in damage to the engine or to the
engine cooling system. Example

batteries provide increased impact
protection to prevent vehicle occupants from
suffering acid burns should the battery be
damaged in the event of an accident.
In order for the battery to achieve the
maximum possible service life, it must always
be sufficiently charged.

frequently if you use the vehicle mainly for
short trips or if you leave it standing idle for
a lengthy period. Consult a qualified specialist
workshop if you wish to leave your vehicle
parked for a long period of time.
Only replace a battery with a battery that has
been recommended by Mercedes-Benz. i

vehicle and do not require any electrical
consumers. The vehicle will then use very
little energy, thus conserving battery
power.
i If the power supply has been interrupted,
e.g. if you reconnect the battery, you will
have to:
R set the clock (audio system/COMAND,
see the separate operating instructions).
R reset the function for folding the exterior
mirrors in/out automatically, by folding
