For more information, see “Manual trans-
mission” (
page 136).
Warning!G
Make sure absolutely no objects are ob-
structing the pedals’ range of movement.
Keep the driver’s footwell clear of all obsta-
cles. If there are any floormats or carpets in
the footwell, make sure the pedals still have
sufficient clearance.
During sudden driving or braking maneuvers
the objects could get caught between the
pedals. You could then no longer brake or
accelerate. This could lead to accidents and
injury.Warning!G
Inhalation of exhaust gas is hazardous to
your health. All exhaust gas contains carbon
monoxide (CO), and inhaling it can cause un-
consciousness and possible 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 with at least one window
fully open.

150 Controls in detail
Instrument cluster
The outside temperature sensor is located
in the front bumper area. Due to its loca-
tion, the sensor can be affected by road or
engine heat during idling or slow driving.
Therefore, the accuracy of the displayed
temperature can only be verified by com-
parison to a thermometer placed next to
the sensor, not by comparison to external
displays (e.g. bank signs, etc.).
When moving the vehicle into colder ambi-
ent temperatures (e.g. when leaving your
garage), you will notice a delay before the
lower temperature is displayed.
A delay also occurs when ambient temper-
atures rise. This prevents inaccurate tem-
perature indications caused by heat
radiated from the engine during idling or
slow driving.Fuel gauge
The fuel gauge is on the left-hand side of
the instrument cluster (
page 26). Once
the fuel level has fallen below the reserve
mark, the yellow fuel tank reserve warning
lamp 4 for the fuel reserve comes on
(
page 380).

Garage door opener*
The integrated remote control is capable of
operating up to three separately controlled
devices. It provides a convenient way to re-
place up to three hand-held remote con-
trols used to operate devices such as
garage door openers, gate openers, or oth-
er devices compatible with HomeLink
® or
some other systems.
Before the integrated remote control can
be used, it must be programmed to the ga-
rage door opener, gate operator or other
device you wish to operate. See the follow-
ing instructions for programming informa-
tion.

button
Warning!G
Before programming the integrated remote
control to a garage door opener or gate
operator, make sure people and objects are
out of the way of the device to prevent po-
tential harm or damage. When programming
a garage door opener, the door moves up or
down. When programming a gate operator,
the gate opens or closes.
Do not use the integrated remote control
with any garage door opener that lacks
safety stop and reverse features as required
by U.S. federal safety standards (this
includes any garage door opener model
manufactured before April 1, 1982).
A garage door that cannot detect an object
– signaling the door to stop and reverse –
does not meet current U.S. federal safety
standards.
When programming a garage door opener,
park the vehicle outside the garage.

Step 7:
To program the remaining two signal
transmitter buttons, repeat the steps
above starting with step 3.
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 the “training” button on the ga-
rage door opener motor head unit.
The “training light” is activated.
You have 30 seconds to initiate the follow-
ing two steps.
Step 10:
Return to the vehicle and firmly press,
hold for 2 seconds and release the pro-
grammed signal transmitter button
(2, 3 or4).
Step 11:
Press, hold for 2 seconds and release
same signal transmitter button a sec-
ond time to complete the training pro-
cess.Step 12:
Confirm the garage door operation by
pressing the programmed signal trans-
mitter button (2, 3 or4).
Step 13:
To program the remaining two signal
transmitter 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.
iIf indicator lamp1 flashes rapidly for about
2 seconds and then turns to a constant light,
continue with programming steps 8 through 12
as your garage door opener may be equipped
with the “rolling code” feature.iSome garage door openers (or other rolling
code equipped devices) may require you to
press, hold for 2 seconds and release the same
signal transmitter button a third time to com-
plete the training process.

Programming tips
If you are having difficulty programming
the integrated remote control, here are
some helpful tips:

Check the frequency of hand-held re-
mote control5 (typically located on
the reverse side of the remote). The in-
tegrated remote control is compatible
with radio-frequency devices operating
between 280-390 MHz.

Put a new battery in hand-held remote
control5. This will increase the likeli-
hood of the hand-held remote control
sending a faster and more accurate sig-
nal to the integrated remote control.

While performing step 3, hold
hand-held remote control5 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 in
(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.
iCertain types of garage door openers are in-
compatible with the integrated remote control. If
you should experience further difficulties with
programming the integrated remote control,
contact an authorized Mercedes-Benz Center, or
call Mercedes-Benz Customer Assistance Cen-
ter (in the USA only) at 1-800-FOR-MERCedes, or
Customer Service (in Canada) at
1-800-387-0100.

320 Operation
Driving instructions
Emission control
Certain systems of the engine and the
emission control system serve to keep the
toxic components of the exhaust gases
within permissible limits required by law.
These systems will function properly only
when maintained strictly according to fac-
tory specifications. Any adjustments on
the engine should, therefore, be carried
out only by qualified Mercedes-Benz Cen-
ter authorized technicians.
Engine adjustments should not be altered
in any way. The specified service proce-
dures must be carried out regularly accord-
ing to Mercedes-Benz servicing
requirements. For details please refer to
the Maintenance Booklet.
Warning!G
As with any vehicle, do not idle, park or op-
erate this vehicle in areas where combusti-
ble materials such as grass, hay or leaves
can come into contact with the hot exhaust
system, as these materials could be ignited
and cause a vehicle fire.
Warning!G
Inhalation of exhaust gas is hazardous to
your health. All exhaust gas contains carbon
monoxide (CO), and inhaling it can cause un-
consciousness and possible 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.
