Particularly avoid fire, open flames, creatingsparks and smoking. Ensure there is sufficient ven-
tilation while charging and jump-starting. Do not lean over abattery.
GWARNING
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.
RMake sure that the positive terminal of aconnected battery does not come into contact with
vehicle parts.
RNever place metal object sortools on abattery.
RIt is importan tthat you observe the described order of the battery terminals when connecting
and disconnectin gabattery.
RWhen jump-starting, make sure that the battery poles with identical polarity are connected.
RIt is particularly importan ttoobserve the described order when connectin gand disconnecting
the jumper cables.
RNever connect or disconnect the battery terminals while the engine is running.
GWARNING
Ad ischarged battery can freeze at temperatures below freezin gpoint. 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 starting attempts. Otherwise, the catalytic converter could be
damaged by the non-combusted fuel.
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 charge
the battery nor jump-start the vehicle. The service life of athawed-out battery may be shorter .The
starting characteristics can be impaired, particularly at low temperatures. Have the thawed-out
battery checked at aqualified specialist workshop.
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:
RThe 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.
RYou may only jump-start the vehicle when the engine and exhaust system are cold.
RDo not start the engine if the battery is frozen. Let the battery thaw first.
RJump-starting may be performed only using batteries with anominal voltage of 12 V.
ROnly use jumper cables which have asufficient cross-section and insulated terminal clamps.
RIf 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 battery slightly.
RMake sure that the two vehicles do not touch.
Make sure that:
Rthe jumper cables are not damaged.
Rwhen the jumper cables are connected to the battery, uninsulated sections of the terminal clamp
do not come into contact with other metal sections.
Rthe jumper cables cannot come into contact with parts which can move when the engine is
running, such as the V-belt pulley or the fan.

Rbulges on tires
Rdeformation or severe corrosion on wheels
Regularly checkt he tire tread depth and the
condition of the tread across the whole width of
the tire (
Ypage 252). In order to inspec tthe
inne rside of the tire surface, turn the steering
wheel to full lock.
All wheels must have avalve cap to protect the
valve against dirt and moisture. Do not install
anythin gontot he valve other than the standard
valve cap or avalve cap approved by Mercedes-
Benzf or your vehicle. Do not use any other valve
caps or systems ,e.g. tire pressure monitoring
systems.
You should regularly checkt he pressure of all
your tires includin gthe spare wheel, particularly
prior to long trips. Adjust the tire pressure as
necessary (
Ypage 254).
The servicel ife of tires depends, among other
things, on the following factors:
RDriving style
RTire pressure
RDistance covered
Notes on tir etread
GWARNING
Insufficientt ire tread will reduce tire traction.
The tire is no longer able to dissipate water.
This means that on wet road surfaces,t he risk
of hydroplaning increases, in particular where speed is not adapted to suit the driving con-
ditions. There is arisk of accident.
If the tire pressure is too high or too low, tires
may exhibit differentl evels of wear at differ-
ent location sonthe tire tread. Thus, you
should regularly checkt he tread depth and
the condition of the tread across the entire
width of all tires.
Minimum tire tread depth for:
RSummer tires: âin (3 mm)
RM+S tires: ãin (4 mm)
For safety reasons ,replace the tires before
the legally prescribed limit for the minimum
tire tread depth is reached.
Marking :shows where the bar indicator
(arrow) for tread wear is integrated int othe tire
tread.
Treadwear indicators (TWI) are required by law. Six indicators are positioned on the tire tread.
They are visible onc eatread depth of approx-
imately áin (1.6 mm) has been reached. If this
is the case, the tire is so worn that it must be
replaced.
Selecting, mounting and replacing
tires
ROnly mount tires and wheels of the same type
and make.
ROnly mount tires of the correct size ont othe
wheels.
RBreak in new tires at moderates peeds for the
first 60 miles (100 km). The new tires only
reach their full performanc eafter this dis-
tance.
RDo not drive with tires which have too little
tread depth, as this significantly reduces the
traction on wet roads (hydroplaning).
RReplace the tires after six years at the latest,
regardless of wear. This also applies to the
spare wheel.
Winter operation
General notes
Have your vehicle winter-proofed at aqualified
specialist workshop at the onset of winter.
Observe the notes in the "Changing awheel"
section (
Ypage 269).
252Winter operation
Wheels and tires

Drivingwiths ummer tires
At temperature sbelo w45‡( +7 †), elasticity in
summe rtires is significantly lower and thus also
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, therebyd amaging the tires permanently.
Mercedes-Benz cannot accep tresponsibility for
this type of damage.
GWARNING
Damaged tires can cause tire inflation pres-
sure loss.Asar esult, you couldlose control of
you rvehicle. There is arisk of accident.
Check the tires regularly for signs of damage
and replace any damaged tires immediately.
M+S tires
GWARNING
M+S tires with atire tread depth of less than
ã 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 ãin
(4 mm) must be replaced immediately.
GWARNING
Wheela nd tire dimensions as wel lasthe type
of tire can vary between the spare wheel and
the wheel to be replaced .When the spare
wheel is mounted ,driving characteristics may
be severely affected .There is arisk of an acci-
dent.
In order to reduce risks:
Ryou should thereforea dapt yourdriving
styl eand drive carefully.
Rnever mount more than one spare wheel
that differs from the wheel to be replaced.
Ronly use aspare wheel that differs from the
wheel to be replaced for ashort time.
Rdo not deactivate ESP®.
Rhave aspare wheel that differs from the
wheel that has beenc hangedreplaced at
the nearest qualified specialist workshop.
You must observe the correct wheel and
tire dimensions as wel lasthe wheel type.
Do not exceed amaximu mspeedof50m ph
(80 km/h) if aspare wheel of adifferent size is
installed.
At temperatures below 45 ‡(+7 †), use winter
tires or all-season tires. Both type softire are
identified by the M+S marking.
Only winter tires bearing the isnowflake
symbol in addition to the M+S marking provide
the best possibleg rip in wintry road conditions.
Only these tires wil lallow driving safety systems
such as ABS and ESP
®to function optimally in
winter. Theset ires have beend eveloped specif-
ically for driving in snow.
Use M+S tires of the same make and tread on all
wheels to maintain safe handling characteris-
tics.
Always observe the maximu mpermissible
speeds pecified for the M+S tires you have
mounted.
When you have mounted the M+S tires:
XCheck the tire pressures (Ypag e257).
XRestart the tire pressure monitor
(Ypag e259).
Snowc hains
GWARNING
If you drive too fast with snow chains moun-
ted, they may snap. As aresult, you could
injure others and damage the vehicle. There is
ar isk of an accident.
Observe the maximu mpermissible speedf or
operation with snow chains.
!Information about the use of snow chain
compatibleA MG winter tires is applicable for
AMG tires. Use of snow chains is only per-
missible with these tires.
!On some tire sizes there is not enoug hspace
for snow chains. To avoi ddamage to the vehi-
cle or tires, observe the "Wheel and tire com-
binations" section unde r"Tires and wheels".
