manual transmission, see “Manual trans-
mission” (
page 48).
Warning!
G
For vehicles equipped with a manual trans-
mission, getting out of your vehicle with the
gearshift lever not engaged in 1st or reverse
gear and parking brake engaged is danger-
ous. Also, when parked on an incline, an en-
gaged 1st 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 56).
When parked on an incline, turn the front
wheel 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 injury.Warning!
G
On slippery road surfaces, never downshift
in order to obtain braking action. This could
result in drive wheel slip and reduced vehi-
cle control. Your vehicle’s ABS will not pre-
vent this type of loss of control.

page 49).
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 gear shift program.
Gearshift pattern for automatic
transmissionThe automatic transmission selects indi-
vidual gears automatically, depending on:
the gear selector lever
position D(
page 162) with gear
ranges 4, 3 , 2 , 1 (
page 161)
the selected program mode ( C/S)
(page 164)
the position of the accelerator pedal
(page 165)
the vehicle speed 1
Current gear range/gear selector lever
position
2 Current program mode
The current gear range/gear selector lever
position and program mode (
C/S) appear
in the multifunction display.
An additional indication of the current gear
selector lever position can be found on the
cover of the shifting-gate.
The indicators come on when you activate
a switch (e.g. unlocking the vehicle or
opening a door) and go out after approxi-
mately 15 minutes.
iDuring the brief warm-up, transmission
upshifting is delayed. This allows the
catalytic converter to heat up more
quickly to operating temperature.

Effect
ì
Park position
Gear selector lever position
when the vehicle is parked. Place
gear selector lever in positionP
only when vehicle is stopped.
The park position is not intended
to serve as a brake when the
vehicle is parked. Rather, the
driver should always set the
parking brake in addition to
placing the gear selector lever in
position P to secure the vehicle.
EffectThe SmartKey can only be
removed from the starter switch
with the gear selector lever in
position P. With the SmartKey
removed, the gear selector lever
is locked in position P.
If the vehicle’s electrical system
is malfunctioning, the gear
selector lever could remain
locked in position P
(page 380).

No power is transmitted from the
engine to the drive axle. When
the brakes are released, the
vehicle can be moved freely

To avoid damage to the trans-
mission, never engage N while
driving.
If the ESP is deactivated or
malfunctioning:
Move gear selector lever to N
only if the vehicle is in danger of
skidding, e.g. on icy roads.
