The ¯ or± service symbol and the ser-

mal operation of the vehicle. Servic ework will
need to be performed more often if the vehicle is operated under arduous conditions or increased
loads, for example:
R regular city driving with frequent intermediate
stops
R if the vehicle is primarily used to travel short
distances
R for frequent operation in mountainous terrain
or on poor road surfaces
R if the engine is often left idling for long periods
In these or similar operating conditions, have,
for example, the air filter, engine oil and oil filter changed more frequently. The tyres must be
checked more frequently if the vehicle is oper-
ated under increased loads. Further information can be obtained at aqualified specialist work-
shop, e.g. aMercedes-Benz Servic eCentre. Fuel/water separator

Before handling the battery, touch the vehicle body to remove any existing electrostatic
build-up.
The highly flammable gas mixture is created
while the battery is charging and when jump-
starting.
Always make sure that neither you nor the bat-
tery is electrostatically charged. Electrostatic
charge is created, for example:
R by wearing synthetic-fibre clothing
R by friction between clothing and the seat
R if you pull or push the battery across carpet or
other synthetic materials
R if you rub the battery with acloth G
WARNING
During the charging process, abattery produ-
ces hydrogen gas. If ashort circui toccurs or
sparks are created ,the hydrogen gas can
ignite. There is arisk of an explosion.
R Make sure that the positive terminal of a
connected battery does not come into con-
tact with vehicl eparts.
R Never place metal objects or tools on abat-
tery.
R It is important that you observe the descri-
bed order of the battery terminal swhen
connecting and disconnecting abattery.
R When jump-starting, make sure that the

Avoid contact with the skin, eyes and clothing. Wea
reye protection. Keep children at
asafe distance. Observe this Owner's Manual.
For safety reasons, Mercedes-Benz recom-
mends that you use only batteries that have
been tested and approved for your vehicle by
Mercedes-Benz. These batteries provide
increased impact protection to prevent the vehi-
cle occupants from suffering acid burns should
the battery be damaged in the event of an acci- dent.
In order for the battery to achieve the maximumpossible service life, it should always be suffi-
ciently charged.
Like other batteries, the vehicle battery may
discharge over time if you do not use the vehicle.
In such cases, have the battery disconnected at aq uali fied specialist workshop .However, you
can also charge the battery with acharger rec-
ommended by Mercedes-Benz. For more infor-
mation, please contact aquali fied specialist
workshop.
Have the battery charge checked more fre-
quently if yo uuse the vehicle mainly for short
trips or if yo uleave it standing idl efor an exten-
ded period .Consul taq ualified specialist work-
shop if yo uwishtol eave your vehicle parked up
for along period of time.
Whe nyou park the vehicle, remove the key if you
do not require any electrica lconsumers. The
vehicle will then use very little energy, thus con- serving battery power.

ninterrupted,

If the warning and indicator lamps do not light up on the instrument cluster when temperatures
are low, it is probably because the discharged battery has frozen. In this case, you may neither
jump-start the vehicle nor charge the battery.
The servic elife of abattery that has been
thawed may be reduced. The starting charac-
teristics may be impaired, especially at low tem- peratures. Have the thawed battery checked at
aq ualified specialist workshop. Jump-starting
For the jump-starting procedure, use only the jump-starting connection point, consisting of apos-
itive terminal and an earth point, in the engine compartment. G

WARNING
If yo umanipulate, bridge or replace afaulty
fuse with afuse of ahigher amperage ,the
electric cables coul dbeoverloaded. This may
result in afire. There is arisk of an accident
and injury.
Always replace faulty fuses with specified new fuses of the correct amperage. The fuses in your vehicle disconnect fault
ycir-
cuits. If afuse blows, all the components in the
circuit and their functions will fail.
Blown fuses must be replaced with fuses of the same rating, which you can recognise by the
colour and fuse rating. The fuse ratings are listed
in the fuse allocation chart (Y page 233).
If the newly inserted fuse also blows, have the
cause traced and rectified at aqualified special-
ist workshop, e.g. aMercedes-Benz Service
Centre.
! Only use fuses that have been approved for
Mercedes-Benz vehicles and which have the
correc tfuse rating for the system concerned.
Otherwise, components or systems could be
damaged.
! Make sure that no moisture can enter the
fuse box when the cover is open.
! When closing the cover, make sure that it is
lying correctly on the fuse box. Moisture seep-

WARNING
Damaged tyres can caus etyre inflation pres-

yourv ehicle. There is arisk of accident.
Check the tyres regularl yfor signs of damage
and replace any damaged tyres immediately.
Check wheels and tyres for damage at least
once amonth. Check wheels and tyres after
driving off-road or on roug hroads. Damaged
wheels can caus ealoss of tyre pressure. Operation
235Wheels and tyres Z

Pay particular attention to damage such as:
R cuts in the tyres
R punctures
R tears in the tyres
R bulges on the tyres
R deformation or severe corrosion on the
wheels
Regularly check the tyre tread depth and the
condition of the tread across the whole width of
the tyre (Y page 236). In order to inspect the
inner side of the tyre surface, turn the steering
wheel to full lock.
All wheels must have avalve cap to protec tthe
valve against dirt and moisture. Do not fit any-
thing ontot he valve other than the standard
valve cap or avalve cap approved by Mercedes-
Benz for your vehicle. Do not fit any other valve caps or systems, e.g. tyre pressure monitors.
You should regularly check the pressure of all
your tyres including the spare wheel, particu-
larly prior to long trips. Adjust the tyre pressure as necessary (Y page 238).
The service life of atyre depends on various fac-
tors, including the following:
R driving style
R tyre pressure
R mileage Notes on th
etyre tread G
WARNING
Insuffic ient tyre tread willr educe tyre trac-
tion. The tyre is no longer abletod issipate
water .This means that on wet road surfaces,
the risk of aquaplaning increases, in particular where spee disnot adapted to suitt he driving
conditions. There is arisk of accident.
If the tyre pressure is too high or too low,t yres
may exhibi tdifferent levels of wearatd iffer-
ent locations on the tyre tread. Thus ,you
should regularl ycheck the tread depth and
the condition of the tread across the entire
width of all tyres.
Minimu mtyre tread depth for:
R summe rtyres: 3mm
R M+S tyres: 4mm For safety reasons, replace the tyre
sbefore
the legally prescribed limit for the minimum
tyre trea ddepth is reached. Select
ing, fitting and replacing tyres G
WARNING
Exceeding the state dtyre load-bearing capa-
city and the approved maximu mspee dcould
leadtot yre damage or the tyre bursting. There
is ar isk of accident.
Therefore, only use tyre types and sizes
approved for yourv ehiclemodel .Observe the
tyre loadr ating and spee drating required for
yourv ehicle.
Pay special attention to country-specific
requirements for tyre approval .These require-
ments may stipulate aspecific tyre type for your
vehicle. Furthermore ,the use of aspecific tyre
type in certain regions and area sofoperation
can be highly beneficial .You can find further
information regarding tyres at specialist tyre
retailers, at qualified specialist workshops or at
any Mercedes-Benz Service Centre.
R Use only tyres and wheels of the same type
and make.
R Fit only tyres of the correct size onto the
wheels.
R Runinn ew tyres at moderate speeds for the
first 100 km. They reach their full perform-
ance only after this distance.
R Do not drive with tyres that have too little
tread depth. This significantly reduces trac-
tion on wet road s(aquaplaning).
R Replace the tyres after six years at the latest,
regardless of wear. This alsoa ppliestothe
spar ewheel. Winter operation
