112 Controls in detailLightingDaytime running lamp mode
Turn exterior lamp switch to
positionM orU.
When the engine is running, the low
beam headlamps are switched on.
In low ambient light conditions, the
following lamps will switch on
additionally:

Tail and parking lamps


License plate lamps


Side marker lamps
For nighttime driving, you should turn the
exterior lamp switch to positionB to
permit activation of the high beam head-
lamps.Canada only:
The daytime running lamp mode is manda-
tory and therefore in a constant mode.
Vehicles with automatic transmission*:
When the engine is running, and you shift
from a driving position to positionN orP,
the low beam headlamps will switch off
with a three-minute delay.
When the engine is running, and you


turn the exterior lamp switch to
positionC, the parking lamps
switch on additionally.


turn the exterior lamp switch to
positionB, the manual headlamp
mode has priority over the daytime run-
ning lamp mode.
The corresponding exterior lamps
switch on (
page 110).USA only:
By default, the daytime running lamp mode
is deactivated. Activate the daytime run-
ning lamp mode using the control system,
see “Setting daytime running lamp mode”
(
page 137).
When the engine is running, and you turn
the exterior lamp switch to
positionCorB, the manual head-
lamp mode has priority over the daytime
running lamp mode.
The corresponding exterior lamps switch
on (page 110).
iWith the daytime running lamp mode
and the exterior lamp switch in
positionM you cannot switch on the
high beam headlamps.
The high beam flasher is available at all
times.

148 Controls in detailAutomatic transmissionFor more information on driving with an au-
tomatic transmission, see the “Getting
started” section (
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 op-
erating 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, dependent
upon


the gear selector lever positionD with
gear ranges4, 3, 2, 1 (
page 150)


transfer case position (HIGH or LOW)


the position of the accelerator pedal
(page 153)


the vehicle speed
The current gear selector lever position
and the transfer case position (HIGH or
LOW) appear in the multifunction display.

2Gear selector lever position/gear
range When the gear selector lever is in
positionD, you can influence transmission
shifting by


limiting the gear range


changing gears manually
iDuring the brief warm-up, transmission
upshifting is delayed. This allows the
catalytic converter to heat up more
quickly to operating temperature.
Warning!
G
It is dangerous to shift the gear 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 engine is idling normally and when
your right foot is firmly on the brake pedal.

149 Controls in detail
Automatic transmission
One-touch gearshifting
Even with an automatic transmission, you
can change the gears manually when the
gear selector lever is in positionD.
Downshifting
Briefly press the gear 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 150).Upshifting

Briefly press the gear 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.
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 gear 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.

150 Controls in detailAutomatic transmissionCanceling gear range limit
Press and hold the gear selector lever
in the D+direction until
Dreappears in
the multifunction display.
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.
Gear ranges
With the gear selector lever in positionD,
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
right (D+).
The selected gear range will appear in the
multifunction display. If you press on the
accelerator when the engine has reached
its rpm limit, the transmission will upshift
beyond any gear range limit selected.
!If the transfer case is in off-road driving
position LOW, the automatic transmis-
sion will not shift up automatically,
even when the engine has reached the
speed limit for that gear. There is a risk
of damaging the engine.
It is very important to make sure the
permissible engine speed is not ex-
ceeded.
