Warning!G
A driver’s attention to the road must always
be his/her primary focus when driving. For
your safety and the safety of others, we rec-
ommend that you pull over to a safe location
and stop before placing or taking a tele-
phone call. If you choose to use the tele-
phone while driving, please use the
hands-free device and only use the tele-
phone when weather, road and traffic condi-
tions permit.
Some jurisdictions prohibit the driver from
using a cellular telephone while driving a ve-
hicle.
Bear in mind that at a speed of just 30 mph
(approximately 50 km/h), your vehicle is
covering a distance of 44 feet
(approximately 14 m) every second.
Never operate radio transmitters equipped
with a built-in or attached antenna (i.e. with-
out being connected to an external antenna)
from inside the vehicle while the engine is
running. Doing so could lead to a malfunc-
tion of the vehicle’s electronic system, pos-
sibly resulting in an accident and/or
personal injury.

Automatic transmission
For more information on driving with an
automatic transmission, see “Automatic
transmission” (
page 58).
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
right of the steering column.

transmission

RReverse gear
NNeutral
DDrive position
iDuring the brief warm-up, transmission
upshifting is delayed. This allows the catalytic
converter (gasoline engine) or the oxidation
catalyst (diesel engine) 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.
