Automatic transmission
Transmission positions
Effect
ì
Park position
Shift into park positionP only
when vehicle is stopped. The
park position is not intended to
serve as a brake when the vehi-
cle is parked. Rather, the driver
should always set the parking
brake in addition to shifting into
park positionP to secure the
vehicle.
!SmartKey:
If you turn off the engine using the
SmartKey and remove the SmartKey
from the starter switch, the transmis-
sion automatically will shift to park
positionP. Keep in mind that turning
off the engine with the SmartKey alone
will not automatically shift the trans-
mission toP. Only when the SmartKey
is removed from the starter switch will
the transmission automatically shift
toP.
KEYLESS-GO*:
If you turn off the engine using the
KEYLESS-GO start/stop button and
open the driver’s door, the transmis-
sion automatically will shift to park
positionP. Keep in mind that turning
off the engine using the KEYLESS-GO
start/stop button alone will not auto-
matically shift the transmission toP.
Only when the driver’s door is opened
will the transmission automatically
shift toP.
Even though this is possible, make it a
practice to always shift into park
positionP before turning off the engine
and removing the SmartKey from the
starter switch, or when using
KEYLESS-GO*, before turning off the
engine with the start/stop button and
opening the driver’s door.Warning!
G
If you want the gear position to remain inN
(for example when the vehicle is pulled
through a car wash), do not remove the
SmartKey from the starter switch or, when
using KEYLESS-GO*, do not turn off the
engine using the KEYLESS-GO start/stop
button* and open the driver’s door. Other-
wise, the transmission will shift toP and
lock the wheels, preventing the vehicle from
being pulled through a car wash.

Gear ranges
With the automatic transmission in drive
positionD, you can limit the transmis-
sion’s gear range by pressing the inside of
one of the steering wheel gearshift but-
tons, and reverse the gear range limit by
pressing the outside of one of the steering
wheel gearshift buttons. The steering
wheel gearshift buttons are located on the
back of the steering wheel (
page 189).
The selected gear range appears in the
multifunction display.
If you press on the accelerator when the
engine has reached its rpm limit, the trans-
mission will upshift beyond any gear range
limit selected.
Warning!
G
When leaving the vehicle, always remove the
SmartKey or SmartKey with KEYLESS-GO*
from the starter switch, take it with you, and
lock the vehicle. Do not leave children unat-
tended in the vehicle, or with access to an
unlocked vehicle. Children could shift the
transmission out of positionP, which could
result in an accident and/or serious person-
al injury.

Rocking the vehicle
Rocking the vehicle by shifting betweenD
andR can help free a vehicle stuck in mud
or snow. The engine control system of this
vehicle electronically limits shifting
betweenD andR to very low speeds
(i.e. approx. 2 mph). To shift betweenD
andR, move the gear selector lever past
the resistance point up or down.
Hill start assist system
On uphill grades, the hill start assist
system maintains the pressure in the
brake system for approximately
one second after you have released the
brake pedal. Therefore, you can start off
smoothly without the vehicle moving im-
mediately after releasing the brake pedal.
The hill start assist system is inactive
on driving downhill
in positionN
with the parking brake setWorking on the vehicle
Towing a trailer
If you tow a trailer, note the following
points:
Manually shift to a lower gear range
(page 187) if the transmission hunts
between gears on inclines.
A lower gear range and reduction of
speed reduces the chance to overload
or overheat the engine.
For more information on trailer towing, see
the “Operation” section (
page 314).
Warning!
G
The hill start assist system is not designed
to function as a parking brake and does not
prevent the vehicle from moving when
parked on an incline.
Always set the parking brake in addition to
shifting to park position
P.
iIf the ESP
® has switched off due to a
malfunction, the hill start assist system
is also unavailable.
Warning!
G
When working on the vehicle, set the
parking brake and shift to park positionP.
Otherwise the vehicle could roll away.
