wheel adjustment is located under the
steering column.
To unlock the steering column, pull
handle out to its stop limit.
Move steering wheel to the desired
position.
Make sure your legs can move freely
and that all the displays (including
malfunction and indicator lamps) on
the instrument cluster are clearly
visible.
Push handle back to its original posi-
tion to relock the steering column.
The steering column is once again
locked into position.
Make sure the steering column is se-
curely locked by trying to move the
steering wheel up and down, in and out
before driving off.Steering wheel adjustment, electrical*!Do not drive the vehicle until you have
properly locked the steering column.
Warning!
G
Do not adjust the steering wheel while driv-
ing. Adjusting the steering wheel while driv-
ing could cause the driver to lose control of
the vehicle.
When leaving the vehicle, always remove the
SmartKey or SmartKey with KEYLESS-GO*
from the starter switch, take it with you, and
lock the vehicle.
Even with the SmartKey or SmartKey with
KEYLESS-GO* removed from the starter
switch or the SmartKey with KEYLESS-GO*
removed from the vehicle, the steering
wheel adjustment feature can be operated
when the driver’s door is open. Therefore,
do not leave children unattended in the ve-
hicle, or with access to an unlocked vehicle.
Unsupervised use of vehicle equipment may
cause an accident and/or serious personal
injury.

Mirrors
Adjust the interior and exterior rear view
mirrors before driving so that you have a
good view of the road and traffic condi-
tions.
iThe memory function* (
page 135)
lets you store the setting for the seat
position together with the setting for
the steering wheel and the exterior rear
view mirrors.
Warning!
G
In case of an accident, liquid electrolyte may
escape the mirror housing if the mirror glass
breaks.
Electrolyte has an irritating effect. Do not al-
low the liquid to come into contact with
eyes, skin, clothing, or respiratory system.
In case it does, immediately flush affected
area with water, and seek medical help if
necessary.!Electrolyte drops coming into contact
with the vehicle paint finish can only be
completely removed while in their
liquid state and by applying plenty of
water.

Vehicle status message memory menu
Use the vehicle status message memory
menu to scan malfunction and warning
messages that may be stored in the

tions or system status the vehicle’s system
has recorded.Warning!
G
Malfunction and warning messages are only
indicated for certain systems and are inten-
tionally not very detailed. The malfunction
and warning messages are simply a remind-
er with respect to the operation of certain
systems and do not replace the owner’s
and/or driver’s responsibility to maintain
the vehicle’s operating safety by having all
required maintenance and safety checks
performed on the vehicle and by bringing
the vehicle to an authorized Mercedes-Benz
Light Truck Center to address the malfunc-
tion and warning messages.

282 Controls in detailUseful featuresSystem self-check
Initially, after switching on the ignition,
malfunctions are detected and indicated
(the indicator lamps in the SOS button, the
Roadside Assistance button• and the
Information button¡ stay on longer
than ten seconds or do not come on). The
message
Malfunction. Drive to work-
shop
appears in the multifunction display.Emergency calls
An emergency call is initiated automatical-
ly following an accident in which the emer-
gency tensioning devices (ETDs) or
air bags deploy.
An emergency call can also be initiated
manually by opening the cover next to the
interior rear view mirror labeled SOS, then
briefly pressing the button located under
the cover. See (
page 284) for
instructions on initiating an emergency call
manually.
Warning!
G
If the indicator lamps on the SOS button, on
the Roadside Assistance button, and/or on
the Information button remain illuminated
continuously in red and/or the message Malfunction. Drive to workshop
is
displayed in the multifunction display after
the system self-check, a malfunction in the
system has been detected.
If a malfunction is indicated as outlined
above, the system may not operate as
expected. Have the system checked at the
nearest Mercedes-Benz Light Truck Center
as soon as possible.

Call priority
If other service calls such as a Roadside
Assistance call or Information call are
active, an Emergency call is still possible.
In this case, the Emergency call will take
priority and override all other active calls.
iThe indicator lamp in the Information
button¡ remains illuminated in red
for approximately ten seconds during
the system self-check after switching
on the ignition (together with the
SOS button and the Roadside
Assistance button•).
See system self-check (
page 282) if
the indicator lamp does not come on in
red or stays on longer than
approximately ten seconds.
If the indicator lamp in the Information
button¡ is flashing continuously
and there was no voice connection to
the Response Center established, then
the Tele Aid system could not initiate
an Information call (e.g. the relevant
cellular phone network is not avail-
able). The message
Call failed
ap-
pears in the multifunction display.
Information calls can be terminated
using thet button on the multi-
function steering wheel or the END But-
ton on the Modular COMAND System.!If the indicator lamps do not start flash-
ing after pressing one of the buttons or
remain illuminated (in red) at any time,
the Tele Aid system has detected a
malfunction or the service is not
currently active, and may not initiate a
call. Visit your authorized
Mercedes-Benz Light Truck Center and
have the system checked or contact
the Response Center at
1-800-756-9018 (in the USA) or
1-888-923-8367 (in Canada) as soon
as possible.
iThe indicator lamp in the respective
button flashes until the call is conclud-
ed. Emergency calls can only be termi-
nated by a Response Center or
Customer Assistance Center represen-
tative, whereas Roadside Assistance
and Information calls can also be termi-
nated by pressing buttont on the
multifunction steering wheel or using
the END button on the Modular
COMAND System.
351 Operation
Tires and wheels
Checking tire pressure electronically
with the Advanced Tire Pressure Moni-
toring System* (Advanced TPMS*)The TPMS only functions on wheels that
are equipped with the proper electronic
sensors. It monitors the tire inflation pres-
sure, as selected by the driver, in all four
tires. A warning is issued to alert you to a
decrease in pressure in one or more of the
tires.
Tire pressure inquiries are made using the
multifunction display.The present inflation
pressures are displayed only after a few
minutes’ travel time.
Switch on the ignition (
page 34).
Press thej or kbutton until
the current inflation pressures for each
tire appear in the multifunction display.
iThe Advanced T
ire P
ressure M
onitoring
S
ystem* (Advanced TPMS*) is
equipped with a combination low tire
pressure/TPMS malfunction telltale in
the instrument cluster (
page 24). De-
pending on how the telltale illuminates,
it indicates a low tire pressure condi-
tion or a malfunction in the TPMS sys-
tem itself:
If the telltale illuminates continu-
ously, one or more of your tires is
significantly under-inflated. There is
no malfunction in the TPMS.
If the telltale flashes for 60 seconds
and then stays illuminated, the
TPMS system itself is not operating
properly.
iPossible differences between the read-
ings of a tire pressure gauge of an air
hose, e.g. gas station equipment, and
the vehicle’s control system can occur.
Usually the readings issued by the con-
trol system are more precise.
iWhen the message
Tire pressure
display appears after driving sev-
eral minutes
appears in the display,
the individual inflation pressure values
are matched with the tires. The individ-
ual values are displayed after a few
minutes driving.
iWith a spare wheel without wheel sen-
sor mounted, the system may still indi-
cate the tire inflation pressure of the
removed wheel for some minutes. If
this happens, keep in mind that the in-
dicated value where the spare wheel is
mounted does not reflect the actual
spare tire inflation pressure.
