sumers, such as seat adjustment
2Ignition (power supply for all electrical
consumers) and driving position
All lamps (except high beam headlamp
indicator lamp and turn signal indicator
lamps unless activated) in the instru-
ment cluster come on. If a lamp in the
instrument cluster fails to come on
when the ignition is switched on, have
it checked and replaced if necessary. If
a lamp in the instrument cluster re-mains on after starting the engine or
comes on while driving, refer to “Lamps
in instrument cluster” (
page 436).
3Starting position
iWhen you switch on the ignition, the indica-
tor and warning lamps (except high beam head-
lamp indicator lamp and turn signal indicator
lamps unless activated) in the instrument cluster
come on. The indicator and warning lamps (ex-
cept high beam headlamp indicator lamp and
turn signal indicator lamps if activated) will go
out when the engine is running. This indicates
that the respective systems are operational.
iIf the SmartKey does not belong to the
vehicle, the SmartKey can be turned in the start-
er switch. However, the ignition does not switch
on and the engine does not start.
iWhen the SmartKey is removed from the
starter switch and the automatic transmission is
in a position other thanP, the automatic trans-
mission automatically shifts toP.
!If the SmartKey cannot be turned in the
starter switch, the battery may not be sufficient-
ly charged.
Check the battery and charge it if necessary
(
page 528).
Get a jump start (page 536).
To prevent accelerated battery discharge or a
completely discharged battery, always remove
the SmartKey from the starter switch when the
engine is not in operation.

SmartKey with KEYLESS-GO*
Vehicles equipped with the KEYLESS-GO
feature are supplied with a SmartKey with
integrated KEYLESS-GO function and a
removable KEYLESS-GO start/stop
button.
With the KEYLESS-GO start/stop button
inserted and the SmartKey with
KEYLESS-GO present in the vehicle, press-
ing the KEYLESS-GO start/stop button
without the brake pedal depressed
corresponds to the various starter
switch positions (
page 44)
with the brake pedal firmly depressed
will start the engine (
page 56)
If you wish or should there be a need to
insert the SmartKey with KEYLESS-GO in
the starter switch, the KEYLESS-GO
start/stop button can be easily removed
by pulling it out of the starter switch.1KEYLESS-GO start/stop button

Insert KEYLESS-GO start/stop
button1 into starter switch2 (if not
inserted already).
Make sure the automatic transmission
is set toP (
page 191).
Do not depress the brake pedal.
iThe KEYLESS-GO start/stop button does
not need to be removed from the starter switch
when you leave the vehicle. However, always
take the SmartKey with KEYLESS-GO with you
when you leave the vehicle. As long as the
SmartKey with KEYLESS-GO is in the vehicle, the
vehicle’s electrical systems can be switched on
or the engine can be started using the
KEYLESS-GO start/stop button.

Warning!G
Do not pass belts over sharp edges. They
could tear.
Do not allow the belt to get caught in the
door or in the seat adjustment mechanism.
This could damage the belt.
Never attempt to make modifications to
seat belts. This could impair the effective-
ness of the belts.
Do not bleach or dye seat belts as this may
severely weaken them. In a crash, they may
not be able to provide adequate protection.
Damaged seat belts or belts that were highly
stressed in an accident must be replaced.
Contact an authorized Mercedes-Benz Light
Truck Center.Warning!G
Inhalation of exhaust gas is hazardous to
your health. All exhaust gas contains carbon
monoxide (CO), and inhaling it can cause un-
consciousness and possible death.
Do not run the engine in confined areas
(such as a garage) which are not properly
ventilated. If you think that exhaust gas
fumes are entering the vehicle while driving,
have the cause determined and corrected
immediately. If you must drive under these
conditions, drive only with at least one win-
dow fully open.

Warning!G
As long as the SmartKey with KEYLESS-GO
is in your vehicle, the vehicle can be started.
Therefore, never leave children unattended
in the vehicle, as they could otherwise acci-
dentally start the engine.
When leaving the vehicle, always take the
SmartKey with KEYLESS-GO with you and
lock the vehicle. Do not leave children unat-
tended in the vehicle, or with access to an
unlocked vehicle.

Driving
Driving off
Depress the brake pedal.
The gear selector lever can now be
used.
Shift automatic transmission toD orR
(
page 191).
Release the brake pedal.
Carefully depress the accelerator
pedal.After a cold start, the automatic transmis-
sion shifts at a higher engine revolution.
This allows the catalytic converter (gaso-
line engine) or the oxidation catalyst (die-
sel engine) to reach its operating
temperature earlier.
iWait for the gear selection process to com-
plete before setting the vehicle in motion.
iShifting from gear positionP to positionR,
N, orD is only possible with the brake pedal
depressed. Without the brake pedal depressed,
the gear selector lever can be moved, but the
parking pawl remains engaged, not allowing
shifting to occur.
!If you hear a warning signal and the
message
Release Parking Brake appears in
the multifunction display when driving off, you
have forgotten to release the parking brake.
Release the parking brake (
page 59).
iOnce the vehicle is in motion, the automatic
central locking system engages and the locking
knobs drop down.
The automatic door lock feature can be
deactivated (
page 180).
You can open a locked door from the inside.
Open door only when conditions are safe to do
so.
Warning!G
On slippery road surfaces, never downshift
in order to obtain braking action. This could
result in drive wheel slip and reduced vehi-
cle control. Your vehicle’s ABS will not pre-
vent this type of loss of control.
Warning!G
It is dangerous to shift the automatic trans-
mission out ofP orN if the engine speed is
higher than idle speed. If your foot is not
firmly on the brake pedal, the vehicle could
accelerate quickly forward or in reverse. You
could lose control of the vehicle and hit
someone or something. Only shift into gear
when the engine is idling normally and when
your right foot is firmly on the brake pedal.

!Shift the automatic transmission to
positionPorR only when the vehicle is stopped
in order to avoid damaging the transmission.
!Do not run cold engine at high engine
speeds. Running a cold engine at high engine
speeds may shorten the service life of the
engine.
!Simultaneously depressing the accelerator
pedal and applying the brakes reduces engine
performance and causes premature brake and
drivetrain wear.

intensity of the rain.

sensitivity.
VFast intermittent wiping
Rain sensor operation with high

uSlow continuous wiping
tFast continuous wipingIntermittent wiping
Only switch on intermittent wiping under
wet weather conditions or in the presence
of precipitation.
When you select intermittent wiping, the
rain sensor is activated. The rain sensor
automatically sets a suitable wiping
interval depending on the wetness of the
sensor surface.
Turn the combination switch to
positionU orV.After the initial wipe, pauses between
wipes are automatically controlled by the
rain sensor.
Single wipe
Press the combination switch briefly in
direction of arrow1 to the resistance
point.
The windshield wipers wipe one time
without washer fluid.
If windshield wipers fail to function at all in the
combination switch positionU orV,
set the combination switch to the next
higher wiper speed
have the windshield wipers checked at the
nearest authorized Mercedes-Benz Light
Truck Center
!Do not leave windshield wipers on an inter-
mittent setting when the vehicle is taken to an
automatic car wash or during windshield clean-
ing. Wipers will operate in the presence of water
sprayed on the windshield, and windshield
wipers may be damaged as a result.
!If you have set intermittent wiping, dirt on
the surface of the rain sensor or optical effects
may cause the windshield wipers to wipe in an
undesired fashion. This could then damage the
windshield wiper blades or scratch the windows.
You should therefore switch off the windshield
wipers when weather conditions are dry.
iIntermittent wiping is interrupted when the
vehicle is at a standstill and a front door is
opened. This protects persons getting into or out
of the vehicle from being sprayed.
Intermittent wiping will be continued when all
doors are closed and
the automatic transmission is set to
positionD orR
or
the wiper setting is changed using the
combination switch
