Pulling away
General notes G
WARNING
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 (Y page 247).
It is only possible to shift the transmission from position Pto the desired position if you depress
the brake pedal. Only then is the parking lock
released. If you do not depress the brake pedal,
the DIRECT SELECT lever can still be moved but the parking lock remains engaged.
i Upshifts take place at higher engine speeds
after a cold start. This helps the catalytic con- verter to reach its operating temperature
more quickly.
Information on automatically releasing the elec-
trical parking brake (Y page 169).
Pulling away with a trailer To ensure that you do not roll backwards when
pulling away on an uphill slope, apply the electric
parking brake. X
Press and hold handle :.
The electric parking brake continues to brake
and prevent the vehicle from rolling back-
wards.
The red !indicator lamp in the instrument
cluster remains lit.
X Depress the accelerator pedal.
X As soon as the vehicle/trailer combination is
held by the driving force of the engine, release
lever :.
the electric parking brake is released
The red !indicator lamp in the instrument
cluster goes out.
Hill start assist Hill start assist helps you when pulling away for-
wards 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
depress it before the vehicle begins to roll. G
WARNING
After a while, hill start assist no longer holds
the vehicle and it may 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 electric parking brake is applied
R ESP ®
is malfunctioning ECO start/stop function
Introduction The ECO start/stop function switches the
engine off automatically if the vehicle is stopped
under certain conditions.
When pulling away again, the engine starts auto-
matically. The ECO start/stop function thereby
helps you to reduce the fuel consumption and
emissions of your vehicle. Driving

WARNING
If you leave children unattended in the vehi-
cle, they may be able to set the vehicle in
motion if, for example, they:
R release the parking brake
R shift the automatic transmission out of park
position P
R start the engine
In addition, they may operate vehicle equip-
ment and become trapped. There is a risk of
an accident and injury.
When leaving the vehicle, always take the key
with you and lock the vehicle. Never leave
children unattended in the vehicle.
! Always secure the vehicle correctly against
rolling away. Otherwise, the vehicle or its driv-
etrain could be damaged.
To ensure that the vehicle is safeguarded
against rolling away unintentionally:
R the electric parking brake must be applied.
R the transmission must be in position Pand the
key must be removed from the ignition lock
R the front wheels must be turned towards the
kerb on steep uphill or downhill gradients
R the empty vehicle must be secured at the
front axle with a wheel chock or similar
object, for example, on uphill or downhill gra- dients
R a laden vehicle must also be secured at the
rear axle with a wheel chock or similar object,
for example, on uphill or downhill gradients Switching off the engine
