Tire pressure
Check tires
The tire pressure in one or more tires is
already below the minimum value.
Carefully bring the vehicle to a halt,
avoiding abrupt steering and braking
maneuvers.
Check and adjust tire pressure as
required.
If necessary, change the wheel.
Check tires
Vehicles with Advanced TPMS*:
The tire pressure in one or more tires is
already below the minimum value.
The respective tire is shown in the
multifunction display.
Carefully bring the vehicle to a halt,
avoiding abrupt steering and braking
maneuvers.
Check and adjust tire pressure as
required.
If necessary, change the wheel.
Warning!
G
Do not drive with a flat tire. A flat tire affects
the ability to steer or brake the vehicle.
You may lose control of the vehicle. Contin-
ued driving with a flat tire will cause exces-
sive heat build-up and possibly a fire.

Reduce vehicle speed.
Set the desired vehicle level again
(page 271).
You are towing a trailer or using acces-
sories that are connected to the trailer
power socket, e.g. a bicycle rack.
Leveling cancelled
You have selected another vehicle
level*.

Reduce speed to
under 20 mph
You are driving too fast for the set vehi-
cle level*.
Do not drive faster than 20 mph
(30 km/h).
Visit workshop
The air suspension* functional only to a
limited extent.
Do not drive faster than 50 mph

Possible solution
Visit workshop
The air suspension* is malfunctioning.
Do not drive faster than 50 mph
(80 km/h) depending on the set vehi-
cle level.
Have the vehicle checked at an autho-
rized Mercedes-Benz Light Truck
Center.
Compressor
cooling down
You have selected a higher vehicle level*.
Due to frequent level changes within a
short period, the compressor must first
cool down.
Let the compressor cool until the
message disappears.
The selected level will be set once the
compressor has cooled.
!
When the message
Compressor cooling
down
appears in the multifunction display,
driving is still possible. Keep in mind that the ride
height of the vehicle is not yet reached, so you
can damage the underbody of the vehicle. The
selected level will be set once the compressor
has cooled.

482 Practical hintsReplacing bulbsBulbs
Safe vehicle operation depends on proper
exterior lighting and signaling. It is there-
fore essential that all bulbs and lamp as-
semblies are in good working order at all
times.
Correct headlamp adjustment is extremely
important. Have headlamps checked and
readjusted at regular intervals and when a
bulb has been replaced. See an authorized
Mercedes-Benz Light Truck Center for
headlamp adjustment.
i
If the headlamps or front fog lamps are
fogged up on the inside as a result of high humid-
ity, driving the vehicle a distance with the lights
on should clear up the fogging.
i
Substitute bulbs will be brought into use
when the following lamps malfunction:
Turn signal lamps
Brake lamps
Parking lamps
Tail lamps
Read and observe the messages in the multi-
function display (
page 458).

506 Practical hintsBleeding the fuel system (diesel engine only)Driving the vehicle until the fuel tank is
empty is not recommended. Otherwise, air
may be sucked into the fuel system. If this
happens, the? malfunction indicator
lamp (USA only) or the± malfunction
indicator lamp (Canada only) comes on
and the engine may not start immediately
after refueling the vehicle.
After refueling:
Make sure the automatic transmission
is set toP.
The gear position indicator in the multi-
function display should be on
P.
Do not depress the accelerator.
Turn the SmartKey in the starter switch
to position 2 for at least 10 seconds
(page 40).
Return the SmartKey in the starter
switch to position 0 (
page 40).
Turn the SmartKey in the starter switch
to position3 (
page 40) and hold it
there for a maximum of 40 seconds or
until the engine runs surge-free.
If the engine does not start:
Wait for approximately 2 minutes.
Turn the SmartKey in the starter switch
to position3 (
page 40) and hold it
there for a maximum of 40 seconds or
until the engine runs surge-free.
If the engine still does not start, do not
make any further attempts to start the
engine. Contact an authorized
Mercedes-Benz Light truck Center or call
Roadside Assistance (page 312).
i
Vehicles with KEYLESS-GO*: If necessary,
remove the KEYLESS-GO start/stop button from
the starter switch (
page 40).
i
When the ?malfunction indicator lamp
(USA only) or the ±malfunction indicator
lamp (Canada only) has been illuminated for the
above condition, it will remain illuminated until
the engine was cycled on and off four times in a
row.

522 Practical hintsFusesThe electrical fuses in your vehicle serve to
switch off malfunctioning power circuits.
If a fuse is blown, the components and sys-
tems secured by that fuse will stop operat-
ing.If a newly inserted fuse blows again, have
the cause determined and rectified by an
authorized Mercedes-Benz Light Truck
Center.
The following aids are available to help you
replace fuses. They are included with the
vehicle tool kit (
page 469):
Fuse chart
The fuse chart explains the fuse alloca-
tion and fuse amperages.
Spare fuses
Fuse extractor
The electrical fuses are located in different
fuse boxes:
Fuse box in engine compartment
(page 523)
Fuse box in cargo compartment
(page 523)
Fuse box in passenger compartment
(page 524)Before replacing fuses:
Apply parking brake (
page 65).
Make sure the automatic transmission
is set toP (
page 187).
The gear position indicator in the multi-
function display should be on
P.
Turn off all electrical consumers.
Turn off the engine (
page 40).
Remove the SmartKey from the starter
switch.
Vehicles with KEYLESS-GO*:
Open the driver’s door (this puts
the starter switch in position0,
same as with the SmartKey re-
moved from the starter switch). The
driver’s door then can be closed
again.
Warning!
G
Only use fuses approved by Mercedes-Benz
with the specified amperage for the system
in question and do not attempt to repair or
bridge a blown fuse. Using other than ap-
proved fuses or using repaired or bridged
fuses may cause an overload leading to a
fire, and/or cause damage to electrical
components and/or systems. Have the
cause determined and remedied by an au-
thorized Mercedes-Benz Light Truck Center.i
A blown fuse must be replaced by an appro-
priate spare fuse (recognizable by its color or the
fuse rating given on the fuse) of the amperage
recommended in the fuse chart. Any
Mercedes-Light Truck Center will be glad to
advise you on this subject.
