Notes on the transmission
G
Risk of accident
The movement of the pedals must not be
impaired in any way. Do not keep any
objects in the driver's footwell. Make sure
that floormats or carpets are correctly
secured and that there is sufficient clear-
ance for the pedals. G
Risk of accident
Do not change down for additional engine
braking on a slippery road surface. This
could cause the drive wheels to lose their
grip and the vehicle could skid. This could
cause you to lose control of your vehicle
and cause an accident. Automatic transmission

Selector lever positions ì
Park position
Prevents the vehicle from rolling
away when stopped. Only move the
selector lever to Pwhen the vehicle
is stationary.
i The key can only be removed
when the selector lever is in posi-
tion P. If the key is removed from
the ignition lock, the selector
lever is locked in position P.í
Reverse gear
Only move the selector lever to
R
when the vehicle is stationary. ë
Neutral
Releasing the brakes will allow you
to move the vehicle freely, e.g. to
push it or tow it.
Do not move the selector lever to
N
while you are driving. The auto-
matic transmission could other-
wise be damaged.
If ESP ®
is deactivated or faulty:
only move the selector lever to Nif
the vehicle is in danger of skidding,
e.g. on icy roads. ê
Drive
The automatic transmission
changes gear automatically. All
forward gears are available.
One-touch gearshifting
When the selector lever is in position
D, you
can perform gearshifts yourself, even on vehi-
cles with automatic transmission.
X To shift up: briefly press the selector lever
to the right towards D+.
The automatic transmission shifts up to the
next gear, depending on the gearshift pro-
gram selected. This also extends the shift
range. X
To shift down: briefly press the selector
lever to the left towards D–.
The automatic transmission shifts down to
the next gear, depending on the gear cur-
rently selected. This also restricts the shift
range.
i To prevent the engine from overrevving,
the automatic transmission does not shift
down if you push the selector lever towards
D– while driving at too high a speed.
X To derestrict the shift range: press and
hold the selector lever towards D+until D
is shown once more in the display.
The automatic transmission shifts from the
current shift range directly to D.
X To select the most effective shift
range: press and hold the selector lever to
the left towards D–.
The automatic transmission will shift to a
range which allows ideal acceleration and
deceleration. To do this, the automatic
transmission will shift down one or more
gears.
i The automatic transmission cannot shift
down beyond second gear. To shift into first
gear, the selector lever must be moved
towards D–again. Controls

Shift ranges When the selector lever is in position
D, it is
possible to restrict or derestrict the shift
range for the automatic transmission.
X Briefly press the selector lever to the right
towards D+or to the left towards D–.
The shift range selected is shown in the
display. The automatic transmission shifts
only as far as the selected gear.
i If the maximum engine speed for the shift
range is reached and you continue to accel-
erate, the automatic transmission shifts up
in order to prevent the engine from over-
revving, even if the shift range is restricted.
! When the transfer case is in the off-road
driving position LOWrange, the automatic
transmission does not shift up, even when
the engine has reached the overrevving
limit. There is then a risk of engine damage.
Make sure that you do not exceed the max-
imum permissible engine speed. Driving situation
è
The braking effect of the engine can
be used in this position. ç
To use the braking effect of the
engine on downhill gradients and
for driving:
R
on steep mountain roads
R in mountainous terrain
R in arduous conditions æ
To use the braking effect of the
engine on extremely steep downhill
gradients and long downhill
stretches
Driving tips
Accelerator pedal position
Your style of driving influences how the auto-
matic transmission shifts gear:
R light throttle: early upshifts
R more throttle: late upshifts
Kickdown
Use kickdown for maximum acceleration. X
Depress the accelerator pedal beyond the
pressure point.
The transmission shifts to a lower gear
depending on the engine speed.
X Ease off the accelerator pedal once the
desired speed is reached.
The automatic transmission shifts back up.
Trailer towing
X Drive in the middle of the engine speed
range on uphill gradients.
X Shift down to shift range 3or 2depending
on the incline of the uphill or downhill gra-
dient (Y page 91), even if cruise control is
activated.
X Shift the transfer case into low-range driv-
ing position LOWon extreme uphill gradi-
ents or steep downhill gradients

97Rev counter
The red band in the rev counter indicates the
engine's overrevving range. The fuel supply is
interrupted to protect the engine when the
red band is reached.
! Do not drive in the overrevving range.
Doing so will damage the engine. H
Environmental note
Avoid driving at high engine speeds, as this
increases your vehicle's consumption
unnecessarily and pollutes the environ-
ment through increased emissions. Outside temperature display
G
Risk of accident
The road surface may be icy, especially in
wooded areas or on bridges, even if tem-
peratures are just above freezing point. The
vehicle could skid if you fail to adapt your
driving style. You should therefore always
adapt your driving style and speed to suit
the weather conditions.
There is a short delay before a change in out-
side temperature is displayed. On-board computer
Points to remember
The on-board computer is activated as soon
as you turn the key to position 1in the ignition
lock. You can use the on-board computer to
call up information relating to your vehicle
and to make and adjust settings.
You can call up the next service due date,
select the display language for the instrument
cluster and set other functions. G
Risk of accident

centrate properly on driving, and could
cause an accident.
