Important safety notes
GWARNING
If children are left unsupervised in the vehicle,
they could:
Ropen the doors, thus endangering other
people or road users.
Rget out and disrupt traffic.
Roperate the vehicle's equipment.
Additionally, children could set the vehicle in
motion if, for example, they:
Rrelease the parking brake.
Rshifting the automatic transmission out of
park position P
RStart the engine.
There is a risk of an accident and injury.
When leaving the vehicle, always take the
SmartKey with you and lock the vehicle. Never
leave children or animals unattended in the
vehicle. Always keep the SmartKey out of
reach of children.
GWARNING
Combustion engines emit poisonous exhaust
gases such as carbon monoxide. Inhaling
these exhaust gases leads to poisoning. There
is a risk of fatal injury. Therefore never leave
the engine running in enclosed spaces with-
out sufficient ventilation.
GWARNING
Flammable materials introduced through
environmental influence or by animals can
ignite if in contact with the exhaust system or
parts of the engine that heat up. There is a risk
of fire.
Carry out regular checks to make sure that
there are no flammable foreign materials in
the engine compartment or in the exhaust
system.

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.
XDepress the brake pedal and keep it
depressed.
XPress the Start/Stop button once
(Ypage 105).
The engine starts.
Starting procedure with the SmartKey
XTurn the SmartKey to position 3in the igni-
tion lock (Ypage 106) and release it as soon
as the engine is running.
If the engine will not start:
XRemove the SmartKey from the ignition lock.
XReinsert the SmartKey into the ignition lock
after a short waiting period.
XTurn the SmartKey to position 2in the igni-
tion lock (Ypage 106).

XTurn the SmartKey to position 3in the igni-
tion lock (Ypage 106) and release it as soon
as the engine is running.
Pulling away
General notes
GWARNING
If the engine speed is above the idling speed
and you engage transmission position Dor R,
the vehicle could pull away suddenly. There is
a risk of an accident.
When engaging transmission position Dor R,
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 (
Ypage 72).
It is only possible to shift the transmission from
position jto the desired position if:
Rthe engine is running and
Ryou 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 (
Ypage 125).
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.

GWARNING
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:
Ryou are pulling away on a level road or on a
downhill gradient
Rthe transmission is in position i
Rthe electric parking brake is applied

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:
Rreduced steering effort and turning circle,
resulting in reduced parking effort.
Rimproved driving stability, e.g. on curves.
Rthe 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
GWARNING
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.
General notes
:ECO start/stop display
If the engine has been switched off automati-
cally by the ECO start/stop function, the è
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:
Rthe ignition was switched off for more than
four hours or
Rthe ECO start/stop function had been activa-
ted before the engine was switched off
