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
recommend that you pull over to a safe
location and stop before placing or taking a
telephone call. If you choose to use the
telephone while driving, please use the
hands-free device and only use the
telephone when weather, road and traffic
conditions permit.
Some jurisdictions prohibit the driver from
using a cellular telephone while driving a
vehicle.
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,
possibly resulting in an accident and
personal injury.

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

you can limit the transmission’s gear range
by pressing the gear selector lever to the
left ( D-), and reverse the gear range limit
by pressing the gear selector lever to the

braking power when driving:

on steep downgrades


in mountainous regions


under extreme operating
conditions
æ
The transmission operates in
first gear only.
For maximum use of engine’s
braking effect on very steep or
lengthy downgrades.

gentler starts. This does not apply if
full throttle is applied or gear
range 1 is selected.


Traction and driving stability are
improved on icy roads.


Upshifts occur earlier even when
you give more gas. The engine then
operates at lower rpms and the
wheels are less likely to spin.
!Never change the program mode when
the gear selector lever is out of
position P. This could result in a
change of driving characteristics for
which you may not be prepared.iThe last selected program
mode ( Sor C) is switched on when
the engine is restarted in the
