Rear towing eye
:is located under the
bumper, on the left-hand side when viewed in
the direction of travel. Towing a vehicle with both axles on
the ground
It is important that you observe the safety
instructions when towing away your vehicle
(Y page 221).
X Switch on the hazard warning lamps
(Y page 82).
i In order to signal a change of direction
when towing the vehicle with the hazard
warning lamps switched on, use the
combination switch as usual. In this case,
only the turn signals for the desired
direction flash. When you reset the
combination switch, the hazard warning
lamps start flashing again.
X Turn the SmartKey to position 2in the
ignition lock (Y page 97).
X When the vehicle is stationary, depress the
brake pedal and keep it depressed.
X Shift the transfer case to
neutral(Y page 131).
X Shift the automatic transmission to
position N.
X Release the brake pedal.
X Release the parking brake (Y page 105).
i The transmission can only change gear if
the battery has sufficient charge.
If you cannot move the selector lever to N,
the propeller shafts to the driven axles
must be removed. 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. Use the towing eyes to pull the vehicle if it
needs to be transported on a trailer or
transporter (Y
page 222).
X Apply the parking brake.
X Turn the SmartKey to position 2in the
ignition lock (Y page 97).
X Move the selector lever to N.
X Shift the transfer case to neutral
(Y page 131).
X Secure the towing cable to the towing eyes
(Y page 222).
X Make sure that the vehicle cannot roll
away.
X Release the parking brake.
X Load the vehicle onto the transporter.
As soon as the vehicle has been loaded:
X Apply the parking brake.
X Shift the automatic transmission to
position P.
X Turn the SmartKey to position 0in the
ignition lock (Y page 97) and remove it.
X Secure the vehicle. Recovering a vehicle that has become
stuck
! When recovering a vehicle that has
become stuck, pull it as smoothly and
evenly as possible. Excessive tractive
power could damage the vehicles.
If the drive wheels have become stuck in
loose or muddy ground, pull the vehicle out
with extreme caution, especially so if the
vehicle is loaded.
Never attempt to recover a stuck vehicle with
a trailer attached.
Pull out the vehicle backwards, if possible
using the tracks it made when it became
stuck. Towing and tow-starting

Some tire pressure tables only show the rim
diameter instead of the complete tire size,
e.g. R16 . The rim diameter is part of the tire
size and can be found on the tire sidewall
(Y page 243).
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 a negative
effect on driving comfort.
If the tire pressure is not set correctly, this
can lead to an excessive build up of heat and
a sudden loss of pressure.
For more information, contact a qualified
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 a tire
blow-out. There is a risk 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 a qualified 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 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. 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.
The tires are cold:
R if the vehicle has been parked without
direct sunlight on the tires for at least three
hours and
R if the vehicle has been driven for less 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
checking the pressure of warm tires. Only
correct the tire pressure if it is too low for the
current operating conditions. If you check the
tire pressure when the tires are warm, the
resulting value will be higher than if the tires
were cold. This is normal. Do not reduce the
tire pressure to the value specified for cold 232
