54 Getting startedDrivingManual transmission
Depress the brake pedal.

Fully depress the clutch pedal.

Move gearshift lever to first gear to
drive forward, or to reverse gear to
drive rearward.

Simultaneously release the brake pedal
and slowly the clutch pedal.

Carefully depress the accelerator
pedal.Automatic transmission*

Depress the brake pedal.

Move gear selector lever to positionD
to drive forward, or to positionR to
drive rearward.

Release the brake pedal.

Carefully depress the accelerator
pedal.!Wait for the gear selection process to
complete before setting the vehicle in
motion.iDuring the brief warm-up, transmission
upshifting is delayed. This allows the
catalytic converter to heat up more
quickly to operating temperature.
Warning!
G
Vehicles with automatic transmission*: It is
dangerous to shift the gear selector lever
out of
PorN if the engine speed is higher
than idle speed. If your foot is not firmly on
the brake pedal, the vehicle could acceler-
ate quickly forward or in reverse. You could
lose control of the vehicle and hit someone
or something. Only shift into gear when the
engine is idling normally and when your right
foot is firmly on the brake pedal.

58 Getting startedDriving
Problems while driving
The engine runs erratically and misfires

An ignition cable may be damaged.


The engine electronics may not be op-
erating properly.


Unburned gasoline may have entered
the catalytic converter and damaged it.

Give very little gas.

Have the problem repaired by an au-
thorized Mercedes-Benz Center as
soon as possible.
The coolant temperature is above
248°F (120°C)
The coolant is too hot and is no longer
cooling the engine.

Stop the vehicle as soon as possible
and turn off the engine. Allow engine
and coolant to cool.

Check the coolant level and add cool-
ant if necessary (
page 313).In case of accident
If the vehicle is leaking gasoline:

Do not start the engine under any cir-
cumstances.

Notify local fire and/or police authori-
ties.
If the extent of the damage cannot be de-
termined:

Notify an authorized Mercedes-Benz
Center.
If no damage can be determined on the


Major assemblies


Fuel system


Engine mount

Start the engine in the usual manner.
!If anything blocks the windshield wip-
ers (leaves, snow, etc.), switch them off
immediately.

For safety reasons, stop the vehicle
in a safe location, turn off the en-
gine and remove the SmartKey
from the starter switch before at-
tempting to remove any blockage.


Remove blockage.


Turn the windshield wipers on
again.
If the windshield wipers fail to function
at all with combination switch in
positionI,


set combination switch to the next
higher wiper speed


have the windshield wipers
checked at the nearest authorized
Mercedes-Benz Center

Automatic transmission*
Automatic transmission*
For more information on driving with an
automatic transmission, see “Automatic
transmission*” (
page 51).
Your vehicle’s transmission adapts its gear
shifting process to your individual driving
style by continually adjusting the shift
points up or down. These shift point adjust-
ments are performed based on current
operating and driving conditions.
If the operating conditions change, the
automatic transmission reacts by
adjusting its shift program.
Gearshift pattern for automatic
transmission
The automatic transmission selects indi-
vidual gears automatically, depending on:

the gear selector lever

gear ranges (page 160)


the selected program mode:

302 OperationDriving instructionsCatalytic 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.
Emission control
Certain engine systems 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
only be carried out 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 accord-
ing to Mercedes-Benz servicing require-
ments. For details refer to the
Maintenance Booklet.
!To prevent damage to the catalytic
converters, 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.
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.
