is a risk of fatal injury. Therefore never leave
the engine running in enclosed spaces
without 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 pedal
when starting the engine.
General notes i
Vehicles with a gasoline engine: the
catalytic converter is preheated for up to
30 seconds after a cold

start. The sound of
the engine may change during this time.

Stop button out of the ignition lock.
X To start a gasoline engine: turn the
SmartKey to position 3 in the ignition lock (Y page 141) and release it as soon as the
engine is running.
X To start a diesel engine: turn the
SmartKey to position 2 in the ignition lock
(Y page 141).
The 0028 preglow indicator lamp in the
instrument cluster lights up.
X When the 0028 preglow indicator lamp
goes out, turn the SmartKey to position
3(Y page 141) and release

it as soon as the
engine is running.
i You can start the engine

without preglow
if the engine is warm.
Using KEYLESS-GO to start the engine You can start the engine if a valid SmartKey
with the integrated KEYLESS-GO function is

When engaging transmission position
D or R,
always firmly depress the brake
pedal and do
not simultaneously accelerate.
i It is only possible to shift the transmission
from position P to the desired position if
you depress the brake pedal. Only then is
the parking lock released. If you do not
depress the brake pedal, you can move the

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
locking feature (Y page 228).
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 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 foot
from the brake pedal to the accelerator pedal
and to depress it before the vehicle begins to
roll. G
WARNING
After a short time, hill start assist will no
longer 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.
X Take your foot off the brake pedal.
The vehicle is then held

for about a second.
X Pull away.

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
without delay.
R If fuel is swallowed, seek medical
assistance without delay. Do not induce
vomiting.
R Immediately change out of clothing which
has come into contact with fuel. G
WARNING
Electrostatic buildup can create sparks and
ignite fuel vapors. There is a risk of fire and
explosion.
Always touch the vehicle body
before opening
the fuel filler flap or touching the fuel pump
nozzle. Any existing electrostatic buildup is
thereby discharged. G
WARNING
Vehicles with a diesel engine:
If you mix diesel fuel with gasoline, the flash
point is lower than that of pure diesel fuel.
When the engine is running, exhaust system
components could overheat without being
noticed. There is a risk of fire.
Never refuel with gasoline. Never

mix gasoline
with diesel fuel.
! Do not use gasoline to refuel vehicles with
a diesel engine. Do not use diesel to refuel
vehicles with a gasoline engine. Do not
switch on the ignition if you accidentally
refuel with the wrong fuel. Otherwise, the
fuel will enter the fuel system. Even small
amounts of the wrong fuel could result in
damage to the fuel system and the engine.
The repair costs are high. Notify a qualified
specialist workshop and have the fuel tank
and fuel lines drained completely. !
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.
Do not get into the vehicle again during the
refueling process. Otherwise, electrostatic
charge could build up again.
If you overfill the fuel tank, fuel could spray
out when the fuel pump nozzle is removed.
