little energy, thus conserving battery
power.
iIf the power supply has been interrupted,
e.g. if you reconnect the battery, you will
have to:
Rset the clock (audio system/COMAND,
see the separate operating instructions).
Rreset the function for folding the exterior
mirrors in/out automatically, by folding

Charging the battery
GWARNING
During charging and jump-starting, explosive
gases can escape from the battery. There is a
risk of an explosion.
Particularly avoid fire, open flames, creating
sparks and smoking. Ensure there is sufficient
ventilation while charging and jump-starting.
Do not lean over a battery.
GWARNING
Battery acid is caustic. There is a risk 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.
GWARNING
Adischarged 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 a risk of an explosion.
Allow the frozen battery to thaw out before
charging it or jump-starting.
!Only use battery chargers with a
maximum charging voltage of 14.8 V.
!Only charge the battery using the jump-
starting connection point.
The jump-starting connection point is in the
engine compartment (Ypage 303).
XOpen the hood.
XConnect the battery charger to the positive
terminal and ground point in the same
order as when connecting the donor
battery in the jump-starting procedure
(Ypage 303).
If, at low temperatures, the indicator lamps/
warning lamps in the instrument cluster do
not light up, it is highly likely that the
discharged battery has frozen.Inthis case
you may neither jump-start the vehicle nor
charge the battery. The service life of a
thawed-out battery may be shorter. The
starting characteristics can be impaired,
particularly at low temperatures. Have the
thawed-out battery checked at a qualified
specialist workshop.
Only charge the installed battery with a
battery charger which has been tested and
approved by Mercedes-Benz. An accessory
battery charge unit specially adapted for
Mercedes-Benzvehicles and tested and
approved by Mercedes-Benzis available. It
permits the charging of the battery in its
installed position. Contact an authorized
Mercedes-Benz Center for further
information and availability. Read the battery
charger's operating instructions before
charging the battery.

Towing the vehicle with the front axle
raised
Only vehicles without 4MATIC can be
towed with the front axle raised.
!Vehicles with 4MATIC must not be towed
with either the front or the rearaxle raised,
as doing so will damage the transmission.
Vehicles with 4MATIC may either be towed
away with both axles on the ground or be
loaded up and transported.
!The ignition must be switched off if the
vehicle is being towed with the front axle
raised.Otherwise, ESP®may intervene and
damage the brake system.
XTurn the SmartKey to position2in the
ignition lock.
XWhen the vehicle is stationary, depress the
brake pedal and keep it depressed.
XShift the automatic transmission to
positionP.
XRelease the brake pedal.
XRelease the electric parking brake.
XSwitch off the automatic locking
(Ypage 208).
XSwitch on the hazard warning lamps
(Ypage 107).
XTurn the SmartKey to position0in the
ignition lock and leave the SmartKey in the
ignition lock.
Observe the important safety notes when
towing your vehicle with the front axle raised
(Ypage 305).
Towingavehicle with both axles on
the ground
iIn orderto signal a change of direction
when towing with the hazard warning lamps
switched on, use the combination switch as
usual.Inthis case, only the indicator lamps
for the direction of travel flash. After
resetting the combination switch, the
hazard warning lamp starts flashing again.
The automatic transmission automatically
shifts to positionPwhen you open the driver's
or front-passenger door or when you remove
the SmartKey from the ignition lock. In order
to ensure that the automatic transmission
stays in positionNwhen towing the vehicle,
you must observe the following points:
XMake sure that the vehicle is stationary.
XTurn the SmartKey to position2in the
ignition lock.
XDepress and hold the brake pedal.
XShift the automatic transmission to
positionN.
XLeave the SmartKey in position2in the
ignition lock.
XRelease the brake pedal.
XRelease the electric parking brake.
XSwitch on the hazard warning lamps
(Ypage 107).
It is important that you observe the safety
instructions when towing away your vehicle
(Ypage 305).
Transporting the vehicle
!You may only secure the vehicle by the
wheels, not by parts of the vehicle such as
axle or steering components. Otherwise,
the vehicle could be damaged.
XTurn the SmartKey to position2in the
ignition lock.
XShift the transmission to positionN.
As soon as the vehicle has been loaded:
XPrevent the vehicle from rolling away by
applying the electric parking brake.
XShift the transmission to positionP.
XTurn the SmartKey to position0in the
ignition lock and remove it.
XSecure the vehicle.
The towing eye can be used to pull the vehicle
onto a trailer or transporter for transporting
purposes.

Example: tire pressure table with tire dimensions
Some tire pressure tables showonly the rim
diameters instead of the full tire size, e.g.
R18.Rim diameter is part of the tire size and
can be found on the tire sidewall
(Ypage 330).
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:
Rif you want to drive with an increased load
and/or
Rif you want to drive at higher road speeds.
iThe tire pressures for increased loads
and/or higher road speeds, shown in the
tire pressure table, may have a negative
effect on driving comfort.
If the tire pressure is not set correctly, this
can lead to an excessivebuild up of heat and
a suddenloss of pressure.
For more information, contact a qualified
specialist workshop.
Important notes on tire pressure
GWARNING
If the tire pressure drops repeatedly, the
wheel, valve or tire may be damaged. Tire
pressure that is too low may result in a tire
blow-out. There is a risk of an accident.
RCheck the tire for foreign objects.
RCheck whether the wheel is losing air or the
valve is leaking.
If you are unable to rectify the damage,
contact a qualified specialist workshop.
GWARNING
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 a risk 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 a suitable pressure gauge to check the
tire pressure. The outer appearance of a tire
does not permit any reliable conclusion about
the tire pressure.
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.
The tires are cold:
Rif the vehicle has been parked without
direct sunlight on the tires for at least three
hours and
Rif the vehicle has not been driven further
than 1 mile (1.6 km)
The tire temperature changes depending on
the outside temperature, the vehicle speed
and the tire load. If the tire temperature
changes by 18 ‡ (10 †), the tire pressure
changes by approximately 10 kPa (0.1 bar/
1.5 psi). Take this into account when
