Starting the engine
Important safety notes
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 orparts 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.
iFor further information about the auto-
matic transmission, see ( Ypage 105).
iIf 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 3
( Y page 103) in the ignition lock and release
it as soon as the engine is running.
iYou can also use the touch-start function.
To do this, turn the SmartKey to position 3
( Y page 103) and release it immediately.
The engine then starts automatically.
Pulling away
Automatic transmission
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.
!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.

iUpshifts 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
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 startassist.
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.
iOnce you have taken your foot off the
brake pedal, the vehicle is held for around
one second.
X Pull away.

GWARNING
Fuel is poisonous and hazardous to health.
There is a risk of injury.
You must make sure that fuel does not comeinto contact with your skin, eyes or clothing
and that it is not swallowed. Do not inhale fuel
vapors. Keep fuel away from children.
If you or others come into contact with fuel,
observe the following:
R Wash away fuel from skin immediately
using soap and water.
R If fuel comes into contact with your eyes,
immediately rinse them thoroughly with
clean water. Seek medical assistance with-
out delay.
R If fuel is swallowed, seek medical assis-
tance without delay. Do not induce vomit-ing.
R Immediately change out of clothing which
has come into contact with fuel.
!Do not use diesel to refuel vehicles with a
gasoline engine. Even small amounts of the wrong fuel result in damage to the fuel sys-
tem and engine.
!Do not switch on the ignition if you acci-
dentally refuel with the wrong fuel. Other-
wise, the fuel will enter the fuel lines. Notify
a qualified specialist workshop and have
the fuel tank and fuel lines drained com-
pletely.
!Overfilling the fuel tank could damage the
fuel system.
!Take care not to spill any fuel on painted
surfaces. You could otherwise damage the
paintwork.
!Use a filter when refueling from a fuel can.
Otherwise, the fuel lines and/or injection
system could be blocked by particles from
the fuel can.
If you overfill the fuel tank, pressure may build
up in the fuel tank. This could cause fuel to
spray out when the fuel pump nozzle is
removed. There is a risk of injury. The fuel tank is full when the fuel pump nozzle first
switches off. End the refueling process.
