vThe yellow ESP® warning lamp
comes on and remains on while
driving.You have engaged the differential locks. The
ABS, ESP®, BAS, EBB and 4-ETS are switched
off.
The driving systems will switch on
again after the differential locks have
been disengaged.
Read and observe messages in the
multifunction display (
page 338).
The ESP® has been switched off with the
ESP® switch or has switched off due to a
malfunction.
Risk of accident!
When the ESP
® is switched off, it will not
stabilize the vehicle if the system recognizes
that the vehicle starts to skid or that a wheel
is spinning.
The cruise control is deactivated and cannot
be switched on.
Switch the ESP® back on (page 95).
Exceptions: (
page 94).
If leaving the ESP® switched off, adapt
your speed and driving to the prevail-
ing road and weather conditions.
If the ESP
® cannot be switched on:
Read and observe messages in the
multifunction display (
page 338).
Continue driving with added caution.
Adapt your speed and driving to the
prevailing road and weather condi-
tions.
Have the system checked at an
authorized Mercedes-Benz Light
Truck Center as soon as possible.

Warning!G
Each tire, including the spare (if provided),
should be checked monthly when cold and
inflated to the inflation pressure recom-
mended by the vehicle manufacturer on the
Tire and Loading Information placard on the
driver’s door B-pillar or, if available, the tire
inflation pressure label on the inside of the
fuel filler flap. If your vehicle has tires of a
different size than the size indicated on the
Tire and Loading Information placard or the
tire inflation pressure label, you should
determine the proper tire inflation pressure
for those tires.
As an added safety feature, your vehicle has
been equipped with a Advanced Tire Pres-
sure Monitoring System (Advanced TPMS)
that illuminates a low tire pressure telltale
when one or more of your tires is signifi-
cantly underinflated. Accordingly, when the
low tire pressure telltale illuminates, you
should stop and check your tires as soon as
possible, and inflate them to the proper
pressure.
Driving on a significantly underinflated tire
causes the tire to overheat and can lead to
tire failure.
Underinflation also reduces fuel efficiency
and tire tread life, and may affect the vehi-
cle’s handling and stopping ability. Please
note that the Advanced TPMS is not a sub-
stitute for proper tire maintenance, and it is
the driver’s responsibility to maintain cor-
rect tire pressure, even if underinflation has
not reached the level to trigger illumination
of the Advanced TPMS low tire pressure tell-
tale.
USA only: Your vehicle has also been
equipped with a Advanced TPMS malfunc-
tion indicator to indicate when the system is
not operating properly. The Advanced TPMS
malfunction indicator is combined with the
low tire pressure telltale. When the system
detects a malfunction, the telltale will flash
for approximately 1 minute and then remain
continuously illuminated. This sequence will
continue upon subsequent vehicle start-ups
as long as the malfunction exists.When the malfunction indicator is
illuminated, the system may not be able to
detect or signal low tire pressure as
intended.
Advanced TPMS malfunctions may occur for
a variety of reasons, including the installa-
tion of replacement or alternate tires or
wheels on the vehicle that prevent the Ad-
vanced TPMS from functioning properly. Al-
ways check the Advanced TPMS
malfunction telltale after replacing one or
more tires or wheels on your vehicle to en-
sure that the replacement or alternate tires
and wheels allow the Advanced TPMS to
continue to function properly.

Vehicle status messages in the
multifunction display
Warning and malfunction messages
appear in the multifunction display located
in the instrument cluster.
Certain warning and malfunction mes-
sages are accompanied by an audible
signal.
Address these messages accordingly and
follow the additional instructions given in
this Operator’s Manual.
Selecting the vehicle status message
memory menu in the control system
(
page 144) displays both cleared and
uncleared messages.High-priority messages appear in the
multifunction display in red color.
Certain messages of high priority cannot
be cleared from the multifunction display
using the reset button (
page 130) or
buttonj,k,·, orè on the
multifunction steering wheel.
Other messages of high priority and
messages of less immediate priority can
be cleared from the multifunction display
using the reset button (
page 130) or
buttonj,k,·, orè on the
multifunction steering wheel. They are
then stored in the vehicle status message
memory (
page 144). Remember that
clearing a message will only make the
message disappear. Clearing a message
will not correct the condition that caused
the message to appear.
Warning!G
All categories of messages contain
important information which should be
taken note of and, where a malfunction is
indicated, addressed as soon as possible at
an authorized Mercedes-Benz Light Truck
Center.
Failure to repair condition noted may cause
damage not covered by the Mercedes-Benz
Limited Warranty, or result in property
damage or personal injury.

Failure to follow these instructions
increases the risk of accident.

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-
