Important safety notes G
WARNING
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. G
WARNING
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.
! Do not depress the accelerator when
starting the engine. Starting procedure X
Shift the automatic transmission to posi-
tion P.
The transmission position display in the
multifunction display shows P.
i For further information about the auto-
matic transmission, see (Y page 139).
i If you depress the brake when starting the
engine, pedal travel is unusually long and
there is less pedal resistance.
X Make sure that the parking brake is
applied.
X Turn the SmartKey to position 3in the igni-
tion lock (Y page 133) and release it as
soon as the engine is running.
i You can also use the touch-start function.
To do this, turn the SmartKey to position 3
(Y page 133) and release it immediately.
The engine then starts automatically. Pulling away
Automatic transmission 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.
! Only shift the automatic transmission to
reverse gear Ror park position Pwhen the
vehicle is stationary. Otherwise, the auto-
matic transmission could be damaged.
! Do not depress the accelerator pedal
while depressing the brake pedal. This
impairs engine performance and results in
premature wear on the brake system and
drivetrain. 134

X Release the brake pedal.
X Carefully depress the accelerator pedal.
i It is only possible to shift the automatic
transmission from position Pto a different
position if you depress the brake pedal.
Only then is the selector lever lock
released.
i 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 208).
i Upshifts take place at higher engine
speeds after a cold start. This helps the
catalytic converter to reach its operating
temperature more quickly.
Hill start assist 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 helps you when pulling away
forwards 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 footfrom the brake pedal to the accelerator pedal
and to depress it before the vehicle begins to
roll.
X Take your foot off the brake pedal.
i Once you have taken your foot off the
brake pedal, the vehicle is held for around
one second.
X Pull away.
Hill start assist will not function if: R you are pulling away on a level road or on a
downhill gradient.
R the transmission is in position N.
R the parking brake is applied.

Driving tips
Accelerator pedal position Your style of driving influences how the auto-
matic transmission shifts gear:
R little throttle: early upshifts
R more throttle: late upshifts
Kickdown Use kickdown for maximum acceleration.
X Depress the accelerator pedal beyond the
pressure point.
The automatic transmission shifts to a
lower gear depending on the engine speed.
X Ease off the accelerator pedal once the
desired speed is reached.
The automatic transmission shifts back up.
Kickdown is not available in the permanent
manual drive program on AMG vehicles.
Rocking the vehicle free Shifting the transmission repeatedly between
gears Dand Rmay help to free the vehicle if it
has become stuck in slush or snow. The vehi-
cle's engine management system limits the
speed to a maximum of 5 mph (9 km/h) when shifting back and forth. To shift back and forth
between transmission positions Dand R,
move the selector lever forwards and back-
wards past the point of resistance.
Towing a trailer X
Drive in the middle of the engine speed
range on uphill gradients.
X Vehicles except AMG vehicles: shift
down to shift range 3or 2depending on the
uphill or downhill gradient (Y page 145),
even if cruise control or SPEEDTRONIC is
activated.
AMG vehicles: shift down to gear 3or 2
depending on the uphill or downhill gradi-
ent (Y page 145), even if cruise control, DISTRONIC PLUS or SPEEDTRONIC is acti-
vated.
X Shift the transfer case into low-range driv-
ing position LOW RANGE on extreme uphill
gradients or steep downhill gradients
