Shift the transmission to position 005D
(Y page 117).
The transmission position indicator on the
multifunction display shows 005D
(Y page 119).
You can start the engine in transmission posi-
tion 005Dand 005C.
Starting procedure with the Start/Stop button The Start/Stop button can be used to start the
vehicle manually without inserting the SmartKey into the ignition lock. You merely need to carry
the SmartKey on your person. This mode for
starting the engine operates independently of
the ECO start/stop automatic engine start func- tion.
You can start the engine if a valid SmartKey is in
the vehicle. Switch off the engine and always
take the SmartKey with you when leaving the
vehicle, even if you only leave it for a short time.
Pay attention to the important safety notes.
X Depress the brake pedal and keep it
depressed.
X Press the Start/Stop button once
(Y page 110).
The engine starts.
Starting procedure with the SmartKey X
Turn the SmartKey to position 0049in the igni-
tion lock (Y page 111) and release it as soon
as the engine is running.
If the engine will not start: X Remove the SmartKey from the ignition lock.
X Reinsert the SmartKey into the ignition lock
after a short waiting period. X
Turn the SmartKey to position 0048in the igni-
tion lock (Y page 111).
The indicator lamps in the instrument cluster light up (Y page 199).
X Turn the SmartKey to position 0049in the igni-
tion lock (Y page 111) and release it as soon

General notes G
WARNING
If the engine speed is above the idling speed
and you engage transmission position 003A
or 0046, the vehicle could pull away suddenly.
There is a risk of an accident.
When engaging transmission position 003Aor
0046, always firmly depress the brake pedal
and do not simultaneously accelerate.
Depress the accelerator carefully when pulling
away.
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 locking
feature (Y page 73).
It is only possible to shift the transmission from position 005Dto the desired position if:
R the engine is running and
R you depress the brake pedal
If you do not depress the brake pedal, the E-
SELECT lever can still be moved but the parking
lock remains engaged.
Information on the automatic release of the
electric parking brake (Y page 130).
Hill start assist Hill start assist helps you when pulling away
forward or in reverse on an uphill gradient. It
holds the vehicle for a short time after you have removed your foot from the brake pedal. This
gives you enough time to move your foot from
the brake pedal to the accelerator pedal and to
depress it before the vehicle begins to roll. 112
DrivingDriving and parking

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 on a
downhill gradient
R the transmission is in position 005C
R the electric parking brake is applied
R ESP ®
is malfunctioning Rear axle steering
General notes Depending on the speed, rear axle steering
adapts the track of the rear axle to the position
of the front wheels. Together with the steering
angle of the front wheels, this results in greater mobility and stability than on vehicles without
rear axle steering.
Rear axle steering has the following character-
istics:
R reduced steering effort and turning circle,
resulting in reduced parking effort.
R improved driving stability, e.g. on curves.
R the vehicle has more direct steering. Control
of the vehicle is thereby increased. ECO start/stop function
Introduction The ECO start/stop function switches the
engine off automatically if the vehicle is stopped
under certain conditions.
The engine starts automatically when the driver
wants to pull away again. The ECO start/stop
function thereby helps you to reduce the fuel
consumption and emissions of your vehicle. Important safety notes G
WARNING
If the engine is switched off automatically and you exit the vehicle, the engine is restarted
automatically. The vehicle may begin moving. There is a risk of accident and injury.
If you wish to exit the vehicle, always turn off
the ignition and secure the vehicle against
rolling away.

ECO start/stop display
If the engine has been switched off automati-
cally by the ECO start/stop function, the 00D6
ECO symbol is shown in the multifunction dis-
play.
The ECO start/stop function is only available in drive program C.
The ECO start/stop function is activated when-
ever you switch on the engine using the Smart-
Key or the Start/Stop button. This is the case if:
R the ignition was switched off for more than
four hours or
R the ECO start/stop function had been activa-
ted before the engine was switched off
Automatic engine switch-off The ECO start/stop function switches the
engine off automatically if:
R the ECO start/stop function is activated
(Y page 114) and
R you brake the vehicle to a standstill in trans-
mission position 005B
The ECO start/stop function is operational
when:
R the indicator lamp in the ECO button is lit
green
R the outside temperature and the atmospheric
air pressure is within the range that is suitable
for the system Driving

All of the vehicle's systems remain active when
the engine is stopped automatically.
The HOLD function can also be activated if the
engine has been switched off automatically. It is then not necessary to continue applying the
brakes during the automatic stop phase. When
you depress the accelerator pedal, the engine
starts automatically and the braking effect of
the HOLD function is deactivated.

start. You cannot hear
the starter motor. The on-board voltage is too low because the battery is too weak or
discharged.
X Jump-start the vehicle (Y page 256).
If the engine does not start despite attempts to jump-start it:
X Consult a qualified specialist workshop. The starter motor was exposed to a thermal load that was too high.
