WARNING
Ad ischarge dbattery can freeze at tempera-
ture sbelow freezing point. Whe njump-start-
ing the vehicl eorcharging the battery ,gases
can escap efrom the battery .There is ariskof
an explosion.
Allow the froze nbattery to tha woutbefore
charging it or jump-starting.
! Onl
yusebattery chargers with amaxi-
mu mc harging voltag eof14.8V.
! Only
charge the battery using the jump-
starting connection point.
The jump-starting connection point is in the
engine compartment (Y page 242).
Neve rcharge the battery if it is stil linstalled in
the vehicle ,unless yo uuseab attery charger
which ha sbeent ested and approved by
Mercedes-Benz. Abattery charge runits pe-
ciall yadapt ed for Mercedes-Benz vehicles

is available as an accessory. It permits the
charging of the battery in its installed posi-
tion. Contact an authorized Mercedes-Benz
Center for further information and availabil-
ity .C harget he battery in accordance with the
separate instructions for the accessory bat-
tery charger.
Read the battery charger's operating instruc- tions before charging the battery.

Jump-starting
G
WARNING
Battery acid is caustic. There is arisk of injury.
Avoid contact with the skin, eyes or clothing. Do not inhale any battery gases. Do not lean over the battery. Keep children away from batteries. Wash battery acid immediately with water and seek
medical attention. G
WARNING
During charging and jump-starting, explosive gases can escape from the battery. There is arisk
of an explosion.
Particularly avoid fire, open flames, creating sparks and smoking. Ensure there is sufficient ven-
tilation while charging and jump-starting. Do not lean over abattery. G
WARNING
During the charging process, abattery produces hydrogen gas. If ashort circuit occurs or sparks
are created, the hydrogen gas can ignite. There is arisk of an explosion.
R Make sure that the positive terminal of aconnected battery does not come into contact with
vehicle parts.
R Never place metal objects or tools on abattery.
R It is important that you observe the described order of the battery terminals when connecting
and disconnecting abattery.
R When jump-starting, make sure that the battery poles with identical polarity are connected.
R It is particularly important to observe the described order when connecting and disconnecting
the jumper cables.
R Never connect or disconnectt he battery terminals while the engine is running.G
WARNING
Ad ischarged battery can freeze at temperatures below freezing point. When jump-starting the
vehicle or charging the battery, gases can escape from the battery. There is arisk of an explosion.
Allow the frozen battery to thaw out before charging it or jump-starting.
! Avoid repeated and lengthy startinga
ttempts. Otherwise, the catalytic converter could be
damaged by the non-combusted fuel.
Do not start the vehicle using arapid charging device. If your vehicle's battery is discharged,
the engine can be jump-started from another vehicle or from asecond battery using jumper
cables. Observe the following points:
R The battery is not accessible in all vehicles. If the other vehicle's battery is not accessible,
jump-start the vehicle using asecond battery or ajump-starting device.
R You may only jump-start the 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 Only jump-start from batteries with a12Vvoltage rating.
R Only use jumper cables which have asufficient cross-section and insulated terminal clamps. 242

Information on driving
R If the vehicle is heavily loaded, chec kthe
tire pressures and correct them if neces-
sary.
R While driving, pay attention to vibrations,
noises and unusual handling characteris-
tics, e.g. pulling to one side. This may indi- cate that the wheels or tires are damaged.If you suspect that atire is defective,
reduce your speed immediately. Stop the
vehicle as soon as possible to chec kthe
wheels and tires for damage. Hidden tire
damage could also be causing the unusual
handling characteristics. If you find no
signs of damage, have the wheels and tires checked at aqualified specialist workshop.

Observe the notes in the "Changing awheel"
section (Y page 270). Drivin
gwiths ummer tires
At temperatures below 45 ‡(+7† ), summer
tires experience aconsiderable loss in elas-
ticity and therefore traction and braking
power. Change the tires on you rvehicle to
M+S tires. Using summe rtires at very cold
temperatures coul dcause cracks to form,
thereb ydamaging the tires permanently.
Mercedes-Benz cannot accep tresponsibility
for this type of damage. M+S tires
G
WARNING
M+S tires with atire tread depth of less than
00CF in (4 mm )are not suitabl efor use in winter
and do not provide sufficient traction. There is
ar isk of an accident.
M+S tires with atread depth of less than 00CFin
(4 mm) must be replaced immediately.
At temperatures below 45 ‡(+7† ), use win-
ter tires or all-season tires. Both type softire
are identified by the M+S marking.
Only winter tires bearing the 004Dsnowflake
symbol in addition to the M+S marking pro-
vide the best possibl egrip in wintry road con-
ditions. Only these tires will allow driving
safety systems such as ABS and ESP ®
to
function optimally in winter. Thi sisbecause
these tires were specifically developed for
driving in snow.
Use M+S tires of the same make and tread on
allw heels to maintain safe handling charac-
teristics.
Always observe the maximu mpermissible
spee dspecified for the M+S tires you have
mounted.
When you have mounted the M+S tires:
X Check the tire pressure s(Ypag e253).
X Restart the tire pressure monitor
(Y pag e259). 252

Snow chains
G
WARNING
If snow chains are installed to the front
wheels, they may drag against the vehicle
body or chassis components. This could
cause damage to the vehicle or the tires.
There is arisk of an accident.
To avoid hazardous situations:
R never install snow chains to the front
wheels
R always install snow chains in pairs to the
rear wheels.
! On some tire sizes there is not enough
space for snow chains. To avoid damage to
the vehicle or tires, observe the "Wheel and tire combinations" section under "Tires and
wheels".
For safety reasons, Mercedes-Benz recom-
mends that you only use snow chains that
have been specially approved for your vehicle by Mercedes-Benz, or are of acorresponding
standard of quality.
R You may not attach snow chains to all
wheel-tire combination ,see the informa-
tion under "Wheels and tires" in the "Tech-
nical data" section.
R Only use snow chains when driving on
roads completely covered by snow.
Remove the snow chains as soon as possi- ble when you come to aroad that is not
snow-covered.
R Local regulations may restrictt he use of
snow chains. Observe the appropriate reg- ulations if you wish to mount snow chains.
R Do not exceed the maximum permissible
speed of 30 mph (50 km/h).
i You can deactivate ESP ®
(Y page 55)
when pulling away with snow chains instal-
led. You can thereby allow the wheels to
spin in acontrolled manner, achieving an
increased driving force (cuttinga ction). Tire pressure

Important safety notes G
WARNING
Underinflated or overinflated tires pose the
following risks:
R the tires may burst, especially as the load
and vehicle speed increase.
R the tires may wear excessively and/or
unevenly, which may greatly impair tire
traction.
R the driving characteristics, as well as steer-
ing and braking, may be greatly impaired.
There is arisk of an accident.
Follow recommended tire inflation pressures
and check the pressure of all the tires includ-
ing the spare wheel:
R monthly, at least
R if the load changes
R before beginning along journey
R under different operating conditions, e.g.
off-road driving
If necessary, correct the tire pressure.

specifications are vehicle-specific and may
deviate from the data shown here. The tire pressure specifications that are valid for
your vehicle can be found on the Tire and
