Have service work carried out as described
in the MaintenanceB ooklet. This may
otherwise lead to increased wear and
damage to the major assemblies or the
vehicle.
Aq ualified specialist workshop, e.g. an
authorize dMercedes-Ben zCenter, will reset

maintenanc ework, for example.
Special service requirements
The specified maintenanc einterval takes only
the normal operation of the vehicle into
account. Under arduous operatin gconditions
or increased load on the vehicle,
maintenanc ework must be carried out more
frequently, for example:
R regular city driving with frequent
intermediate stops
R if the vehicle is primarily used to travel
short distances
R use in mountainous terrain or on poor road
surfaces
R if the engin eisoften left idling for long
periods 310
MaintenanceMaintenance and care

The battery and the cover of the positive
terminal clamp must be installed securely
during operation.
Comply with safety precautions and take
protective measures when handling
batteries. Risk of explosion.
Fire, open flames and smokin
gare
prohibited when handling the
battery. Avoid creatin gsparks. Battery acid is caustic. Avoid
contact with skin, eyes or clothing.
Wear suitable protective clothing,
especially gloves, apron and
faceguard.
Rinse any acid spills immediately
with clear water. Contact a
physician if necessary.
Wear eye protection.
Keep children away.
Observe this Operator's Manual.
For safety reasons, Mercedes-Benz
recommends that you only use batteries
which have been tested and approved for
your vehicle by Mercedes-Benz.T hese
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.
The vehicle battery, like other batteries, can
discharge over time if you do not use the
vehicle. In this case, have the battery disconnected at
aqualified specialist
workshop. You can also charge the battery
with acharger recommended by Mercedes-
Benz.C ontactaqualified specialist workshop
for further information.
Have the battery condition of charge checked
more frequently if you use the vehicle mainly
for short trips or if you leave it standin gidle
for alengthy period. Consult aqualified
specialist workshop if you wish to leave your
vehicle parked for along period of time.
i Remove the SmartKey if you park the
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.I nformation on setting the
clock can be found in the separate
operating instructions.
On vehicles with COMAND and a
navigation system, the clock is set
automatically.
R reset the function for folding the exterior
mirrors in/out automatically, by folding
the mirrors out once (Y page 110). Charging the battery

Example: tire pressure table with tire dimensions
If at ire size precedes atire pressure, the tire
pressure informatio nfollowing is only valid
for that tire size. The load conditions "partially
laden" and "fully laden" are defined in the
table for different numbers of occupant sand
amounts of luggage. The actual number of
seats may differ. Some tire pressure tables show only the rim
diameters instead of the full tire size, e.g.
R18.T he rim diameter is part of the tire size
and can be found on the tire sidewall
(Y page 351).
If the tire pressures have been set to the
lower values for lighter loads and/or lower
road speeds, the pressures should be reset
to the higher values:
R if you want to drive with an increased load
and/or
R if you want to drive at higher road speeds.
i The tire pressures for increased loads
and/or higher road speeds, shown in the
tire pressure table, may have anegative
effect on driving comfort. If the tire pressure is not set correctly, this
can lead to an excessive build up of heat and
as
udden loss of pressure.
For more information, contact aqualified
specialist workshop. Important notes on tire pressure
G
WARNING
If the tire pressure drops repeatedly, the
wheel, valve or tire may be damaged. Tire
pressure that is too low may result in atire
blow-out. There is arisk of an accident.
R Check the tire for foreign objects.
R Check whether the wheel is losing air or the
valve is leaking.
If you are unable to rectify the damage,
contact aqualified specialist workshop. G
WARNING
If you fit unsuitable accessories onto tire
valves, the tire valves may be overloaded and
malfunction, which can cause tire pressure
loss. Due to their design, retrofitted tire
pressure monitors keep the tire valve open.
This can also result in tire pressure loss. There
is ar isk of an accident.
Only screw the standard valve cap or other
valve caps approved by Mercedes-Benz for
your vehicle onto the tire valve.
Use asuitable pressure gauge to check the
tire pressure. The outer appearance of atire
does not permit any reliable conclusion about
the tire pressure. On vehicles equipped with
the electronic tire pressure monitoring
system, the tire pressure can be checked
using the on-board computer.
The tire temperature and pressure increase
when the vehicle is in motion .This is
dependent on the driving speed and the load.
Therefore, you should only correct tire
pressures when the tires are cold. Check
