Telephone*
Radio transmitters, such as a portable tele-
phone or a citizens band unit, should only
be used inside the vehicle if they are con-
nected to an antenna that is installed on
the outside of the vehicle.
The external antenna must be approved by
Mercedes-Benz. Please contact an autho-
rized Mercedes-Benz Light Truck Center
for information on the installation of an ap-
proved external antenna. Refer to the radio
transmitter operation instructions regard-
ing use of an external antenna.
Warning!
G
Whenever you are using floormats, make
sure there is enough clearance and that the
floormats are securely fastened.
Floormats should always be securely fas-

.
Before driving off, check that the floormats
are securely in place and adjust them if nec-
essary. A loose floormat could slip and
hinder proper functioning of the pedals.
Do not place several floormats on top of
each other as this may impair pedal move-
ment.
iTo install or remove the floormat more
easily, move the driver’s seat or front
passenger seat as far to the rear as
possible (
page 39).
Warning!
G
Never operate radio transmitters equipped
with a built-in or attached antenna (i.e. with-
out being connected to an external antenna)
from inside the vehicle while the engine is
running. Doing so could lead to a malfunc-
tion of the vehicle’s electronic system, pos-
sibly resulting in an accident and/or serious
personal injury.

The Tele Aid system
(Tele

emand)
The Tele Aid system consists of three
types of response:

automatic and manual emergency


roadside assistance


information
The Tele Aid system is operational provid-
ing that the vehicle’s battery is charged,
properly connected, not damaged and cel-
lular and GPS coverage is available.
The speaker volume of a Tele Aid call can
be adjusted when using the volume control
on the Modular COMAND System or on the
multifunction steering wheel. To raise, turn
the rotary volume control on Modular
COMAND System clockwise or press
buttonæ on the multifunction steering
wheel. To lower, turn the rotary volume
control on Modular COMAND System con-trol counterclockwise or press
buttonç on the multifunction steering
wheel.

To activate, press the SOS button, the
Roadside Assistance button• or
the Information button¡, depend-
ing on the type of response required.iThe SOS button is located in the over-
head control panel.
The Roadside Assistance button•
and the Information button¡ are
located below the center armrest
cover.!The Tele Aid system utilizes the cellular
network for communication and the
GPS (G
lobal P
ositioning S
ystem) satel-
lites for vehicle location. If either of
these signals are unavailable, the
Tele Aid system may not function and if
this occurs, assistance must be sum-
moned by other means.
iWhen a Tele Aid call has been initiated,
the Modular COMAND System audio is
muted and the selected mode (radio,
CD etc.) pauses. The optional cellular
phone (if installed) inserted in cradle
switches off. If you must use this
phone, we recommend that you use it
only with the vehicle at a standstill in a
safe location. Remove the phone from
the cradle and place the call. The navi-
gation* system (if engaged) will contin-
ue to run. The display in the instrument
cluster is available for use, and spoken
commands are only available by press-
ing the RPT button on the Modular
COMAND System. A pop-up window
will appear in the Modular COMAND
System display to indicate that a Tele
Aid call is in progress. After the TeleAid
call has ended, the optional cellular
phone inserted in the cradle switches
on again. A PIN entry might be neces-
sary.

Rolling code programming
To train a garage door opener (or other
rolling code devices) with the rolling code
feature, follow these instructions after
completing the “Programming” portion
(steps 1 through 6) of this text. (A second
person may make the following training
procedures quicker and easier.)
Step 8:
Locate “training” button on the garage
door opener motor head unit.
Exact location and color of the button
may vary by garage door opener brand.
Depending on manufacturer, the
“training” button may also be referred
to as “learn” or “smart” button. If there
is difficulty locating the transmitting
button, refer to the garage door opener
operator’s manual.Step 9:

Press “training” button on the garage
door opener motor head unit.
The “training light” is activated.
You have 30 seconds to initiate the
following step.
Step 10:

Firmly press, hold for two seconds and
release the programmed integrated
signal transmitter button (1, 2
or3).
Step 11:

Press, hold for two seconds and
release same button a second time to
complete the training process.
Some garage door openers (or other rolling
code equipped devices) may require you to
perform this procedure a third time to
complete the training.Step 12:

Confirm the garage door operation by
pressing the programmed integrated
signal transmitter button (1, 2
or3).
Step 13:

To program the remaining two buttons,
repeat the steps above starting with
step 3.
Gate operator/Canadian programming
Canadian radio-frequency laws require
transmitter signals to “time-out” (or quit)
after several seconds of transmission
which may not be long enough for the
integrated signal transmitter to pick up the
signal during programming. Similar to this
Canadian law, some U.S. gate operators
are designed to “time-out” in the same
manner.

320 OperationDriving instructionsControl and operation of radio transmitters
Modular COMAND System, radio and
telephone*Telephones and two-way radios
Radio transmitters, such as a portable
telephone or a citizens band unit should
only be used inside the vehicle if they are
connected to an antenna that is installed
on the outside of the vehicle.
Refer to the radio transmitter operation
instructions regarding use of an external
antenna.
Catalytic converter
Your Mercedes-Benz is equipped with
monolithic-type catalytic converters, an
important element in conjunction with the
oxygen sensors to achieve substantial con-
trol of the pollutants in the exhaust emis-
sions. Keep your vehicle in proper
operating condition by following our rec-
ommended maintenance instructions as
outlined in your Maintenance Booklet.
Warning!
G
Do not forget that your primary responsibili-
ty is to drive the vehicle. Only operate the
Modular COMAND System, radio or
telephone
1 if road, weather and traffic con-
ditions permit.
Bear in mind that at a speed of just 30 mph
(approximately 50 km/h), your vehicle is
covering a distance of 44 feet (approximate-
ly 14 m) every second.
1Observe all legal requirements.
Warning!
G
Never operate radio transmitters equipped
with a built-in or attached antenna (i.e. with-
out being connected to an external antenna)
from inside the vehicle while the engine is
running. Doing so could lead to a malfunc-
tion of the vehicle’s electronic system,
possibly resulting in an accident and/or
personal injury.
!To prevent damage to the catalytic con-
verters, use only premium unleaded
gasoline in this vehicle.
Any noticeable irregularities in engine
operation should be repaired promptly.
Otherwise, excessive unburned fuel
may reach the catalytic converter,
causing it to overheat and potentially
start a fire.

353 Operation
Tires and wheels
Reactivating Advanced TPMS*
The TPMS must be reactivated when you
have adjusted the tire inflation pressure to
a new level (e.g. because of different load
or driving conditions). The TPMS is then
recalibrated to the current tire inflation
pressures.
Using the tire placard on the driver’s
door B-pillar (
page 339) or, if avail-
able, the supplemental tire pressure
information on the inside of the fuel fill-
er flap (
page 346), make sure the tire
inflation pressure of all four tires is cor-
rect.

Press buttonè orÿ on the mul-
tifunction steering wheel repeatedly
until the standard display menu ap-
pears in the multifunction display
(page 156).
iIf a condition causing the TPMS to mal-
function develops, it may take up to
10 minutes for the system to signal a
malfunction using the TPMS telltale
flashing and illumination sequence.
The telltale extinguishes after a few
minutes driving if the malfunction has
been corrected.iOperating radio transmission equip-
ment (e.g. wireless headsets, two-way
radios) in or near the vehicle could
cause the TPMS to malfunction.
iReactivate the TPMS after adjusting
the tire inflation pressure to the infla-
tion pressure recommended for the
vehicle operating condition. Tire pres-
sure should only be adjusted on cold
tires. Observe the recommended tire
inflation pressure on the placard on the
driver’s door B-pillar (
page 339).
Some vehicles may have supplemental
tire pressure information for driving at
high speeds (
page 346) or for vehicle
loads less than the maximum loaded
vehicle condition (
page 346). If such
information is provided, it can be found
on the inside of the fuel filler flap.
