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-
o m m e n d t h a t y o u p u l l o v e r t o a s a f e l o c a t i o n
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 approximately
44 feet (approximately 13.5 m) every sec-
ond.
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*
Automatic transmission*
Information for driving with an automatic
transmission is found in the “Getting start-
ed” section (
page 44).
Your transmission adapts its gear shifting
process to your individual driving style by
continually adjusting the shift points up or
down. These shift point adjustments are
performed based on current operating and
driving conditions.
If the operating conditions change the au-
tomatic transmission reacts by adjusting
its gear shift program.The automatic transmission selects indi-
vidual gears automatically, depending on


the selector lever positionD with gear
ranges4, 3, 2, 1 (
page 137)


the selected shift program (W/S)
(page 139)


the position of the accelerator pedal
(page 140)


the vehicle speed
The current selector lever position and
shift program (W/S) appear in the multi-
function display (
page 107).
An additional indication of the current se-
lector 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 approximately
15 minutes.When the selector lever is in positionD,
you can influence transmission shifting by


limiting the gear range


changing gears yourself
iDuring the brief warm-up the transmis-
sion upshifting is delayed. This allows
the catalytic converter to heat up more
quickly to operating temperatures.
Warning!
G
It is dangerous to shift the selector lever out
ofP orN 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 en-
gine is idling normally and when your right
foot is firmly on the brake pedal.

136 Controls in detailAutomatic transmission*One-touch gearshifting
Even with an automatic transmission you
can change the gears yourself when the
selector lever is in positionD.
Downshifting
Briefly press the selector lever to the
left in the D–direction.
The transmission will shift from the current
gear to the next lower gear. This action si-
multaneously limits the gear range of the
transmission (
page 137).Upshifting

Briefly press the selector lever to the
right in the D+direction.
The transmission will shift from the current
gear to the next higher gear as permitted
by the shift program. This action simulta-
neously extends the gear range of the
transmission.Canceling gear range limit

Press and hold the selector lever in the
D+direction until D reappears in the
tachometer display field.
The transmission will shift from the current
gear range directly to gear rangeD.
Shifting into optimal gear range

Press and hold the gear selector lever
in the D–direction.
The transmission will automatically select
the gear range suited for optimal accelera-
tion and deceleration. This will involve
shifting down one or more gears.
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.
iTo avoid overrevving the engine when
the selector lever is moved to the
D–direction, the transmission will not
shift to a lower gear if the engine’s
max. speed would be exceeded.

Gear ranges
With the selector lever in positionD, you
can limit the transmission’s gear range by
pressing the lever to the left (D-), and re-
verse the gear range limit by pressing the
lever to the right (D+).
The selected gear range will appear in the
tachometer display field. If you press on
the accelerator when the engine has
reached its rpm limit, the transmission will
upshift beyond any gear range limit
selected.

Press the program mode selector
switch repeatedly until the letter of the
desired shift program appears in the
multifunction display (
page 107).
Select
Wfor winter driving:


The vehicle starts out in second
gear (both forward and reverse) for
gentler starts. This does not apply if
full throttle is applied or gear
range1 is selected.


Traction and driving stability are im-
proved 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.


The power transmission ratio for se-
lector lever positionR changes de-
pending on the program mode
selected (
W or
S).
Warning!
G
When leaving the vehicle, always remove the
key from the starter switch, and lock the ve-
hicle. Do not leave children unattended in
the vehicle, or with access to an unlocked
vehicle. Children could move the selector le-
ver from positionP, which could result in an
accident and/or serious personal injury.
!Never change the program mode when
the selector lever is out of positionP. It
could result in a change of driving char-
acteristics for which you may not be
prepared.
