Automatic transmission
For more information on driving with an
automatic transmission, see “Automatic
transmission” (
page 54).
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.

transmission

R Reverse gear

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 pedal’s 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.
