This marking tells you about the type of
cord and number of plies in the sidewall
and under the tread.
Tire and loading terminology
Accessory weight
The combined weight (in excess of those
standard items which may be replaced) of
automatic transmission, power steering,
power brakes, power windows, power
seats, radio, and heater, to the extent that
these items are available as
factory-installed equipment (whether
installed or not).
Air pressure
The amount of air inside the tire pressing
outward on each square inch of the tire.
Air pressure is expressed in pounds per
square inch (psi), or kilopascal (kPa) or
bars.
Aspect ratio
Dimensional relationship between tire
section height and section width
expressed in percentage.
Warning!
G
The temperature grade for this tire is estab-
lished for a tire that is properly inflated and
not overloaded. Excessive speed, underin-
flation, or excessive loading, either sepa-
rately or in combination, can cause
excessive heat build-up and possible tire
failure.
iFor illustration purposes only. Actual
data on tires are specific to each vehi-
cle and may vary from data shown in
above illustration.

398 OperationVehicle careHand-wash
Do not use hot water or wash your vehicle
in direct sunlight.
Only use a mild car wash detergent,
such as Mercedes-Benz approved Car
Shampoo.
Thoroughly spray the vehicle with a dif-
fused jet of water.
Direct only a very weak spray towards
the ventilation intake.
Use plenty of water and rinse the
sponge and chamois frequently.
Rinse with clean water and thoroughly
dry with a chamois.
Do not allow cleaning agents to dry on
the finish.Automatic car wash
You can have your car washed in an auto-
matic car wash from the start. Automatic
car washes without brushes are prefera-
ble.
If the vehicle is very dirty, prewash it be-
fore running it through the automatic car
wash.
!If you want the gear position to remain
inN (for example when the vehicle is
pulled through a car wash)
do not remove the SmartKey from
the starter switch
or, when using KEYLESS-GO*
do not turn off the engine using the
KEYLESS-GO start/stop button*
and open the driver’s door
Otherwise, the transmission will shift
toP and lock the wheels, preventing
the vehicle from being pulled through a
car wash.
!Due to the width of the vehicle, fold in
exterior rear view mirrors prior to run-
ning the vehicle through an automatic
car wash to prevent damage to the
mirrors.
Make sure that the windshield wiper
switch is set to0 (
page 59). Other-
wise, the rain sensor could activate and
cause the wipers to move unintention-
ally. This may lead to vehicle damage.
iAfter running the vehicle through an au-
tomatic car wash, wipe any wax off of
the windshield (
page 400). This will
prevent smears and reduce wiping
noise which can be caused by residual
wax on the windshield.
When leaving the car wash, make sure
that the mirrors are folded out. Other-
wise they may vibrate.

404 Practical hintsWhat to do if …Lamps in instrument clusterGeneral information:
If any of the following lamps in the instru-
ment cluster fails to come on during thebulb self-check when switching on the
ignition, have the respective bulb checked
and replaced if necessary.Problem
Possible cause/consequence
Suggested solution
-
The yellow ABS indicator lamp
comes on while the engine is
running.
ABS has detected a malfunction and has
switched off. The BAS, ESP
®, and 4-ETS are
also switched off (see messages in multifunc-
tion display).
The brake system is still functioning normally
but without the ABS available.
If the ABS control unit is malfunctioning,
other systems such as the navigation
system* or the automatic transmission may
also be malfunctioning.
Continue driving with added caution.
Wheels may lock during hard braking,
reducing steering capability.
Read and observe messages in the
multifunction display (
page 416).
Have the system checked at an
authorized Mercedes-Benz Light
Truck Center as soon as possible.
Failure to follow these instructions
increases the risk of an accident.
The charging voltage has fallen below
10 volts. The ABS has switched off.
The battery might not be charged sufficiently.
Switch off electrical consumers that
are currently not needed, e.g. seat
heating*.
If necessary, have the generator
(alternator) and battery checked.
When the voltage is above this value
again, the ABS is operational again.

478 Practical hintsFlat tire
Preparing the vehicle
Park the vehicle in a safe distance from
moving traffic on a hard, flat surface
when possible.
Turn on the hazard warning flasher
(page 153).
Turn the steering wheel so that the
front wheels are in a straight-ahead
position.
Set the parking brake (
page 65).
Set the automatic transmission to P
(page 197).
Vehicles with SmartKey:
Turn off the engine (
page 66).
Remove the SmartKey from the starter
switch.Vehicles with KEYLESS-GO*:
Turn off the engine by pressing the
KEYLESS-GO* button once
(page 66).
Open the driver’s door (this puts the
starter switch in position 0, same as
with the SmartKey removed from the
starter switch). The driver’s door then
can be closed again.
Have any passenger exit the vehicle at
a safe distance from the roadway.
Warning!
G
The dimensions of the spare wheel are dif-
ferent from those of the road wheels. As a
result, the vehicle handling characteristics
change when driving with a spare wheel
mounted. Adapt your driving style accord-
ingly.
The spare wheel is for temporary use only.
When driving with spare wheel mounted,
ensure proper tire inflation pressure and do
not exceed a vehicle speed of
50 mph (80 km/ h).
Drive to the nearest Mercedes-Benz Light
Truck Center as soon as possible to have the
spare wheel replaced with a regular road
wheel.
Never operate the vehicle with more than
one spare wheel mounted.
Do not switch off the ESP
® with a spare
wheel mounted.
iOpen doors only when conditions are
safe to do so.

501 Practical hints
Towing the vehicle
Installing towing eye bolts
The front towing eye is located behind a
cover on the passenger side below the
front bumper.
1Towing eye cover
iThe vehicle cannot be started via
tow-start.iIf the battery is disconnected or dis-
charged, the automatic transmission
will remain locked in positionP and the
SmartKey will not turn in the starter
switch. For more information, see “Bat-
tery” (
page 487) and “Jump starting”
(
page 496).
!When towing the vehicle with all wheels
on the ground, note the following:
With the automatic central locking
activated and the ignition in position2
(page 38), the vehicle doors lock if
the left front wheel is turning at a speed
of approx. 9 mph (15 km / h) or above.
To prevent the vehicle doors from
locking, deactivate the automatic
central locking (
page 130).
Switch off the tow-away alarm
(
page 107).
Towing of the vehicle should only be
done using the towing eye. Never
attach tow cable, tow rope or tow rod
to vehicle chassis, frame or suspension
parts.
