Reprogramming a single signal trans-
mitter button
To program a device using a signal trans-
mitter button previously trained, follow
these steps:
Switch on the ignition (
page 36).
Press and hold the desired signal
transmitter button (2, 3 or4).
Do not release the button.
The indicator lamp1 will begin to
flash after 20 seconds. Without releas-
ing the signal transmitter button, pro-
ceed with programming starting with
step 3.Operation of integrated remote control
Switch on the ignition (
page 36).
Select and press the appropriate inte-
grated signal transmitter button (2,
3 or4) to activate the remote con-
trolled device.
The integrated remote control trans-
mitter continues to send the signal as
long as the button is pressed – up to
20 seconds.
iUpon completion of programming the
integrated remote control, make sure
you retain the hand-held remote con-
trol that came with the garage door
opener, gate operator or other device.
You may need it for use in other vehi-
cles, for future programming of an
integrated remote control, or simply for
continued use as a hand-held remote
control to operate the respective
device in other situations.

Useful features
Erasing the integrated remote control
memory
Switch on the ignition (
page 36).
Simultaneously press and hold down
the outer signal transmitter buttons2
and 4, for approximately 20 seconds,
until the indicator lamp1 flashes rap-
idly. Do not hold for longer than
30 seconds.
The codes of all three channels are
erased.Programming tips
If you are having difficulty programming
the integrated remote control, here are
some helpful tips:
Check the frequency of the hand-held
remote control5 (typically located on
the reverse side of the remote). The in-
tegrated remote control is compatible
with radio-frequency devices operating
between 288-399 MHz.
Put a new battery in the hand-held re-
mote control5. This will increase the
likelihood of the hand-held remote con-
trol sending a faster and more accurate
signal to the integrated remote control.
While performing step 3, hold the
hand-held remote control6 at differ-
ent lengths and angles from the signal
transmitter button (2, 3 or4) you
are programming. Attempt varying an-
gles at the distance of 2 to 5 inches
(5 to 12 cm) away or the same angle at
varying distances.
If another hand-held remote control is
available for the same device, try the
programming steps again using that
other hand-held remote control. Make
sure new batteries are in the hand-held
remote control before beginning the
procedure.
Straighten the antenna wire from the
garage door opener assembly. This
may help improve transmitting and/or
receiving signals.
iIf you sell your vehicle, erase the codes
of all three channels.
iCertain types of garage door openers
are incompatible with the integrated
remote control. If you should experi-
ence further difficulties with program-
ming the integrated remote control,
contact an authorized Mercedes-Benz
Center, or call Mercedes-Benz
Customer Assistance Center (in the
USA only) at 1-800-FOR-MERCedes, or
Customer Service (in Canada) at
1-800-387-0100.

313 Operation
Driving instructions
Emission control
Certain systems of the engine serve to
keep the toxic components of the exhaust
gases within permissible limits required by
law.
These systems, of course, will function
properly only when maintained strictly ac-
cording to factory specifications. Any ad-
justments on the engine should, therefore,
be carried out only by qualified
Mercedes-Benz Center authorized techni-
cians. Engine adjustments should not be
altered in any way. Moreover, the specified
service jobs must be carried out regularly
according to Mercedes-Benz servicing re-
quirements. For details refer to the
Maintenance Booklet.
Warning!
G
Inhalation of exhaust gas is hazardous to
your health. All exhaust gas contains carbon
monoxide, and inhaling it can cause uncon-
sciousness and lead to death.
Do not run the engine in confined areas
(such as a garage) which are not properly
ventilated. If you think that exhaust gas
fumes are entering the vehicle while driving,
have the cause determined and corrected
immediately. If you must drive under these
conditions, drive only with at least one win-
dow fully open at all times.

458 Practical hintsTowing the vehicle
!
To be certain to avoid a possibility of
damage to the drivetrain, however, we
recommend the drive shaft be discon-
nected at the rear axle drive flange (ve-
hicles with 4MATIC: disconnected at
the front and rear axle drive flanges) for
any towing beyond a short tow to a
nearby garage.
Warning!
G
If circumstances require towing the vehicle
with all wheels on the ground, always tow
with a tow bar if:
the engine will not run
there is a malfunction in the electrohy-
draulic brake system
there is a malfunction in the power sup-
ply or in the vehicle’s electrical system
as that will be necessary to adequately con-
trol the towed vehicle.
Prior to towing the vehicle with all wheels on
the ground, make certain the SmartKey is in
starter switch position2.
If the SmartKey is left in the starter switch
position0 for an extended period of time, it
can no longer be turned in the switch. In this
case, the steering is locked. To unlock, re-
move SmartKey from starter switch and re-
insert.
Warning!
G
The brake system requires electrical power
to operate.
A malfunction in the vehicle’s power supply
or electrical system may impair brake sys-
tem operation and switch it into its emer-
gency operation mode. To brake, the driver
must then apply significantly greater brake
pedal pressure and depress the pedal much
further to obtain the expected braking ef-
fect. If necessary, apply full pressure to the
brake pedal. Brakes may only be applied to
the front wheels. Stopping distance is in-
creased! Adapt your driving style according-
ly. For more information, refer to
“Electrohydraulic brake system”
(page 97).
With the engine not running, there is no
power assistance for the steering system. In
this case, it is important to keep in mind that
a considerably higher degree of effort is nec-
essary to steer the vehicle. Adapt your driv-
ing accordingly.
