H
USA only:
Combination low tire pres-
sure/TPMS malfunction telltale
for the TPMS illuminates contin-
uously.
Canada only:
Low tire pressure telltale for the
Advanced TPMS* illuminates
continuously.
The TPMS (USA only) or Advanced TPMS*
(Canada only) detects a loss of pressure in
at least one tire.

Carefully bring the vehicle to a halt,
avoiding abrupt steering and braking
maneuvers. Observe the traffic situation
around you.

Read and observe messages in the
multifunction display.
If the tire inflation pressure in the respec-
tive tire(s) has (have) been corrected, the
combination low tire pressure/TPMS mal-
function telltale goes out after few minutes
driving.
H
USA only:
Combination low tire pres-
sure/TPMS malfunction telltale
for the TPMS flashes
60 seconds and then stays
illuminated.
There is a malfunction in the TPMS.

Read and observe messages in the
multifunction display.

Have the TPMS checked by an
authorized Mercedes-Benz Light Truck
Center.
After the malfunction has been remedied
the combination low tire pressure/TPMS
malfunction telltale goes out after few
minutes driving.

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
vehicle placard or the tire inflation pressure
label. (If your vehicle has tires of a different
size than the size indicated on the vehicle
placard or the tire inflation pressure label,
you should determine the proper tire infla-
tion pressure for those tires).
As an added safety feature, your vehicle has
been equipped with a tire pressure monitor-
ing system (TPMS) that illuminates a low tire
pressure telltale when one or more of your
tires is significantly underinflated. Accord-
ingly, when the low tire pressure telltale illu-
minates, you should stop and check your
tires as soon as possible, and inflate them to
the proper pressure. Driving on a significant-
ly underinflated tire causes the tire to over-
heat 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 TPMS is not a substitute for
proper tire maintenance, and it is the driv-
er’s responsibility to maintain correct tire
pressure, even if underinflation has not
reached the level to trigger illumination of
the TPMS low tire pressure telltale.
USA only:
Your vehicle has also been equipped with a
TPMS malfunction indicator to indicate
when the system is not operating properly.
The TPMS malfunction indicator is com-
bined 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 subse-
quent vehicle start-ups as long as the mal-
function exists. When the malfunction
indicator is illuminated, the system may not
be able to detect or signal low tire pressure
as intended.
TPMS malfunctions may occur for a variety
of reasons, including the installation of in-
compatible replacement or alternate tires or
wheels on the vehicle that prevent the TPMS
from functioning properly. Always check the
TPMS malfunction telltale after replacing
one or more tires or wheels on your vehicle
to ensure that the replacement or alternate
tires and wheels allow the TPMS to continue
to function properly.

The front passenger
front air bag off indicator
lamp illuminates and re-

the weight of a typical
adult or someone larger
than a small individual on
the front passenger seat.
The system is malfunctioning.

Have the system checked as soon as
possible by an authorized
Mercedes-Benz Light Truck Center.

Also read and observe messages in
the multifunction display and follow
corrective steps (
page 440).

The front passenger
front air bag off indicator
lamp does not illuminate
and/or does not remain
illuminated with the
weight of a typical
12-month-old child in a
standard child restraint or
less on the front passen-
ger seat.
The system is malfunction-
ing.

Make sure there is nothing between seat cushion and
child seat and check installation of the child seat.

Make sure no objects applying supplemental weight
onto the seat are present.

Make sure no objects which apply forces to the seat are
present (e.g. objects such as books, briefcases etc.
lodged behind or around the seat, head restraints push-
ing against roof etc.). The system may recognize such
forces as supplemental weight.

If the front passenger front air bag off indicator lamp re-
mains out, have the system checked as soon as possible
by an authorized Mercedes-Benz Light Truck Center. Do
not transport a child on the front passenger seat until
the system has been repaired.

Also note any messages in the multifunction display and
follow corrective steps (
page 440).

428 Practical hintsWhat to do if …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 messag-
es 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 163) 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 145) or
buttonj,k,ÿ, orè on the
multifunction steering wheel.
Other messages of high priority and mes-
sages of less immediate priority can be
cleared from the multifunction display
using the reset button (page 145) or
buttonj,k,ÿ, orè on the
multifunction steering wheel. They are
then stored in the vehicle status message
memory (
page 163). Remember that
clearing a message will only make the mes-
sage 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 dam-
age or personal injury.

On the pages that follow, you will find a
compilation of the most important warning
and malfunction messages that may
appear in the multifunction display.
For your convenience the messages are
divided into two sections:

Text messages (
page 430)


Symbol messages (
page 446)
Warning!
G
No messages will be displayed if either the
instrument cluster or the multifunction
display is inoperative.
As a result, you will not be able to see infor-
mation about your driving conditions, such
as speed or outside temperature, warn-
ing/indicator lamps, malfunction/warning
messages or the failure of any systems.
Driving characteristics may be impaired.
If you must continue to drive, please do so
with added caution. Visit an authorized
Mercedes-Benz Light Truck Center as soon
as possible.
i
Switching on the ignition causes all
instrument cluster lamps (except high beam
headlamp indicator lamp, and turn signal
indicator lamps unless activated) as well as the
multifunction display to come on. Make sure the
lamps and multifunction display are in working
order before starting your journey.
