Manual transmission
Manual transmission
Manual transmission is standard equip-
ment on select models and not available
on all models.
For information on driving with a manual
transmission, see “Driving off”
(
page 53).
Warning!G
For vehicles equipped with a manual trans-
mission, getting out of your vehicle with the
gearshift lever not engaged in first or
reverse gear and the parking brake not
engaged is dangerous.
Also, when parked on an incline, an engaged
first or reverse gear alone may not prevent
your vehicle from moving, possibly hitting
people or objects.
Always set the parking brake in addition to
engaging first or reverse gear (
page 59).
W h e n p a r k e d o n a n i n c line, turn front wheels
towards the road curb.
Do not park this vehicle in areas where com-
bustible 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
When leaving the vehicle, always remove the
SmartKey from the starter switch, take it
with you, and lock the vehicle. Do not leave
children unattended in the vehicle, or with
access to an unlocked vehicle. Children
could move the gearshift lever, which could
result in an accident and/or serious
personal injury.
Warning!G
On slippery road surfaces, never downshift
in order to obtain braking action.
This could result in drive wheel slip and
reduced vehicle control. Your vehicle’s ABS
will not prevent this type of loss of control.

Shifting into reverse
Stop the vehicle completely.
Fully depress the clutch pedal.
Move the gearshift lever to the neutral
position (no gear selected).
Move the gearshift lever to the left until
you feel a certain resistance.
Push the gearshift lever past this
resistance.
Then move the gearshift lever forward
into positionR.
!When you are shifting into the5th or6th
gear, make sure that you press the gearshift
lever to the right. Otherwise, you could acciden-
tally shift into the3rd or4th gear and damage
the transmission.
Downshifting gears leading to overrevving the
engine can result in engine damage that is not
covered by the Mercedes-Benz Limited
Warranty.
Never hold the vehicle stopped on a hill by using
the clutch pedal. The clutch may be damaged
which is not covered by the Mercedes-Benz
Limited Warranty.
Do not exceed the engine speed limits. Refer to
tachometer (
page 119) for engine speeds.
!Only shift into reverse gearR when the
vehicle is stationary, as the transmission could
otherwise be damaged.

For more information on driving with an
automatic transmission, see “Driving off”
(
page 53).
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.
Gear selector lever
The gear selector lever is located on the
lower part of the center console.

iDuring the brief warm-up, transmission
upshifting is delayed. This allows the catalytic
converter to heat up more quickly to operating
temperature.
Warning!G
Make sure that absolutely no objects are
obstructing 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 that 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.
iThe current gear selector lever positionP,
R,N orD appears in the multifunction display
(

There are additional indicators on the
cover of the shifting gate showing the
current gear selector lever position.
The indicators come on when you insert
the SmartKey into the starter switch, and
go out when you remove the SmartKey
from the starter switch.
Shifting procedure
The automatic transmission selects indi-
vidual gears automatically, depending on:

gear selector lever positionD
(
page 157) with gear ranges
(
page 160)

the selected program mode:
(C/S)(
page 161)
or
(M/C/S)* (
page 165)

the position of the accelerator pedal
(
page 159)

the vehicle speedWhen the gear selector lever is in drive
positionD, you can influence transmission
shifting by:

limiting the gear range

changing gears manually
Warning!G
It is dangerous to shift the gear selector
lever out of park positionP or neutral
positionN if the engine speed is higher than
idle speed. If your foot is not firmly on the
brake pedal, the vehicle could accelerate
quickly forward or 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.
!Allow engine to warm up under low load use.
Do not place full load on the engine until the
operating temperature has been reached.
Shift into reverse gearR or park positionP only
when the vehicle is stopped.
Avoid spinning of a drive wheel for an extended
period when driving off on slippery road
surfaces. This may cause serious damage to the
drivetrain which is not covered by the
Mercedes-Benz Limited Warranty.

to placing the gear selector lever
in park positionP to secure the
vehicle.
Effect
The SmartKey can only be
removed from the starter switch
with the gear selector lever in
park positionP. With the

Effect
ëNeutral
No power is transmitted from the
engine to the drive axle. When
the brakes are released, the
vehicle can be moved freely
(pushed or towed).
To avoid damage to the trans-
mission, never engage neutral
positionN while driving.
If the ESP
® is deactivated or
malfunctioning:
Move gear selector lever to neu-
tral positionN only if the vehicle
is in danger of skidding, e.g. on
icy roads.
êDrive

automatically. All forward gears
are available.
!Coasting the vehicle, or driving for any other
reason with gear selector lever in neutral
positionN can result in transmission damage
that is not covered by the Mercedes-Benz
Limited Warranty.
Warning!G
Getting out of your vehicle with the gear
selector lever not fully engaged in park
positionP is dangerous. Also, park
positionP alone is not intended to or capa-
ble of preventing your vehicle from moving,
possibly hitting people or objects.
Always set the parking brake in addition to
shifting to park positionP (
page 59).
When parked on an incline, turn the front
wheels towards the road curb.
Do not park this vehicle in areas where com-
bustible materials such as grass, hay or
