The vehicle locks centrally once you have
pulled away. The locking knobs in the doors
drop down. You can open the doors from
the inside at any time.
You can also deactivate the automatic lock-
ing feature
(Y page 76).Hill start assist
Hill start assist helps you when pulling away
forwards or in reverse on an uphill gradient.
Hill start assist automatically maintains the
brake pressure for about another second, after
you have taken your foot off the brake pedal.
This gives you enough time to move your foot
from the brake pedal to the accelerator pedal
and depress it before the vehicle begins to
roll. G
WARNING
After a short time, hill start assist will no lon-
ger brake your vehicle and it could roll away.
There is a risk of an accident and injury.
Therefore, quickly move your foot from the
brake pedal to the accelerator pedal. Never
leave the vehicle when it is held by hill start
assist.
Hill start assist is not active if:
R you are pulling away on a level road or a
downhill gradient
R the transmission is in position N
R the parking brake is applied
R ESP ®
is malfunctioning Backing up warning device

WARNING
Other road users may ignore or fail to hear
the warning tone of the reverse warning fea-
ture. There is a risk of injury if you fail to
ensure that the area in which you are
maneuvering is clear.
Make sure that there are no persons or
objects in the area in which you are maneu-
vering. It may be necessary to enlist the
help of a second person when maneuvering.
The reverse warning feature is a system
designed to assist you in ensuring the safety
of other road users.
A warning signal sounds to alert other road
users when reverse gear is engaged. The vol-
ume of the warning tone can be reduced for
night-time driving.
X To reduce the volume of the warning
tone: engage reverse gear twice in quick
succession.
The warning tone is now quieter.
i The warning tone sounds at a normal vol-
ume by default. The volume of the warning
tone has to be reduced each time you
engage reverse gear if necessary. Driving

The automatic transmission
changes gear itself. All forward
gears are available.
You can influence gearshifts with
your choice of drive program. You
can also restrict the shift range. Transmission position and drive pro-

The transmission positions and current drive
program : are shown at the bottom of the
instrument cluster display. The current trans-
mission position is highlighted.
In drive program M, the transmission position
indicator shows the current gear in position D
( Y page
135).
If you restrict the shift range, the transmission
position indicator shows the current transmis-
sion position plus restricted shift range =,
e.g. D2 ( Y page 133).
The arrows in the transmission position display
show how and into which transmission posi-
tions you can change using the DIRECT
SELECT lever. Changing gear
The automatic transmission adapts to your
individual driving style by continuously adjust-
ing its shift points. These shift point adjust-
ments take into account the current operating
and driving conditions. If the operating or driv-
ing conditions change, the automatic transmis-
sion reacts by adjusting the gearshift program.
When the automatic transmission is in trans-
mission position h, it shifts the individual
gears automatically.
This depends on the following factors:
R the drive program selected ( Y page 134)
R any restriction in the shift range
(Y page

133)
R the position of the accelerator pedal
R the road speed
You can also change gear manually if you

If the driver's seat belt is fastened and all
doors are closed, Active Parking Assist is acti-
vated automatically when driving forwards.
The system is operational at speeds of up to
approximately
22 mph (35 km/h). While in
operation, the system independently locates
and measures parking spaces on both sides of
the vehicle.
Active Parking Assist will only detect parking
spaces:
R parallel or at right angles to the direction of
travel
R that are parallel to the direction of travel
and are at least 59 in (1.5 m) wide
R that are parallel to the direction of travel
and at least 40 in (1.0 m) longer than your
vehicle
R that are at right angles to the direction of
travel and at least 40 in (1.0 m) wider than
your vehicle i
Note that Active Parking Assist cannot
measure the length of a parking space if it is
at right angles to the direction of travel. You
will need to judge whether your vehicle will
fit in the parking space.
When the vehicle is driving at speeds of up to
approximately

20 mph (30 km/h), parking
symbol ; is shown as a status display in the
header.
The system detects and differentiates between
parking spaces which are parallel or at right
angles to the direction of travel. When a park-
ing space is detected, an arrow appears next
to parking symbol ; to indicate which side
the parking space is on. The parking space is
displayed while you are driving past it and until
you are approximately 50 ft (15 m) away from
it.
Active Parking Assist displays parking spaces
on the passenger side as standard. The park-
ing spaces on the driver's side are only dis-
played if you operate the turn signal on the
driver's side. When parking on the driver's
side, you must operate the turn signal until
you have started active parking assistance by
pressing the a button on the steering
wheel.

WARNING
If you leave the driver's seat when the vehi-
cle is only being braked by Active Parking
Assist, the vehicle could roll away if:
R there is a malfunction in the system or in
the voltage supply.
R the electrical system in the engine com-
partment, the battery or the fuses are
tampered with.
R the battery is disconnected.
R the vehicle is accelerated, e.g. by a vehi-
cle occupant.
There is a risk of an accident.
