Important safety notes
G
WARNING
Flammable material such as leaves, grass or
twigs may ignite if they come into contact with
hot parts of the exhaust system or exhaust
gas flow. There is a risk of fire.
Park the vehicle so that no flammable
materials come into contact with parts of the
vehicle which are hot. Take particular care not
to park on dry grassland or harvested grain
fields. G
WARNING
If you leave children unsupervised in the
vehicle, they could set it in motion by, for
example:
R release the parking brake.
R shift the automatic transmission out of the
parking position P.
R start the engine. In addition, they may operate vehicle
equipment and become trapped. 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 unsupervised in the vehicle.
! If the engine speed is too high or if the
vehicle is rolling, do not shift the
transmission directly from Dto R, from R
to Dor directly to P.
Do not open the driver's door while the
vehicle is in motion. At low speeds in
transmission position Dor R, park position
P is otherwise engaged automatically.
The transmission could be damaged.
! Always secure the vehicle correctly
against rolling away. Otherwise, the vehicle
or its drivetrain could be damaged. Parking
131Driving and parking Z

To ensure that the vehicle is secured against
rolling away unintentionally:
R the electric parking brake must be applied.
R the transmission must be in position P.
R the SmartKey must be in position 0in the
ignition lock and then removed from the
ignition lock, or the Start/Stop button must
be pressed.
R on steep uphill or downhill gradients, turn
the front wheels towards the curb.
R on steep uphill or downhill gradients, the
front axle of an empty vehicle must be
secured, for example with a wheel chock.
R on steep uphill or downhill gradients, the
rear axle of a laden vehicle must be
additionally secured, for example with a
wheel chock. Switching off the engine
Important safety notes G
WARNING
When the engine is switched off, the
transmission shifts into neutral position N.
The vehicle may roll away. There is a risk of
an accident.
After switching off the engine, always switch
to parking position P. Prevent the parked
vehicle from rolling away by applying the
parking brake.
! Do not open the driver's door while the
vehicle is in motion. At low speeds in
transmission position Dor R, park position
P is otherwise engaged automatically. This
can damage the transmission.
