KEYLESS-GO
General notes
R
Do not keep the KEYLESS-GO key:
-with electronic devices, e.g. a mobile
phone or another SmartKey
- with metallic objects, e.g. coins or metal
foil
- inside metallic objects, e.g. a metal case
This can impair the functionality of the
KEYLESS-GO key.
Vehicles with KEYLESS-GO are equipped with
aS martKey featuring an integrated KEYLESS-
GO function and a detachable Start/Stop
button.
The Start/Stop button must be inserted in the
ignitio nlock and the SmartKey must be in the
vehicle.
Pressing the Start/Stop button several times
in succession corresponds to the different
key positions in the ignition lock. This is only
the case if you are not depressing the brake
pedal.
If you depress the brake pedal and press the
Start/Stop button, the engine starts
immediately.
The Start/Stop button can be removed from
the ignition lock. Then, you can insert the
SmartKey into the ignition lock.
i You do not have to remove the Start/Stop
button from the ignition lock when you
leave the vehicle. You should, however,
always take the SmartKey with you when
leaving the vehicle. The vehicle can be
started with the Start/Stop button if the
SmartKey is in the vehicle. 0002

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.
i It is only possible to shift the transmission
from position Pto the desired position if
you depress the brake pedal. Only then is
the selector lever lock released.
X Depress the brake pedal and keep it
depressed.
X Shift the transmission to position Dor R.
X Release the parking brake (Y page 149).
X Release the brake pedal.
X Carefully depress the accelerator pedal.
! If a warning tone sounds and the
Release Park. Brake message appears
in the multifunction display, the parking
brake is still applied. Release the parking
brake.
i The vehicle locks centrally once you have
pulled away.T he 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 201).
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 starta ssist 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.
Hill start assist is not active if:
R you are pulling away on a level road or on
a downhill gradient.
R the transmission is in position N.

or discharged.
X
Jump-start the vehicle (Y page 288).
If the engine does not start despite attempts to jump-start it:
X Consult a qualified specialist workshop. The starter motor was exposed to a thermal load that was too high.

AMG vehicles When shifting down, the double-clutch
function is active regardless of the currently
selected drive program. The double-clutch
function reduces load change reactions and
is conducive to a sporty driving style. The
sound generated by the double-clutch
function depends on the drive program
selected. Kickdown Use kickdown for maximum acceleration.

You must make sure that fuel does not come
into 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
without delay.
R If fuel is swallowed, seek medical
assistance without delay. Do not induce

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.
! 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

WARNING
The automatic transmission switches to
neutral position Nwhen you switch off the
engine. The vehicle may roll away.T here 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.

WARNING
If you must brake the vehicle with the parking
brake, the braking distanc eis considerably
longer and the wheels could lock. There is an
increased danger of skidding and accidents.
Only use the parking brake to brake the
vehicle when the service brake is faulty. Do
not apply the parking brake too firmly. If the
wheels lock, release the parking brake until
the wheels begin turning again. G
WARNING
If you leave children unsupervised in the
vehicle, they could set it in motion by, for
example:
R releasing the parking brake
R shifting the automatic transmission out of
the parking position P
R starting the engine.
They could also operate the vehicle's
equipment. There is a risk of an accident and

Important safety notes G
WARNING
If you shift down on a slippery road surface in
an attempt to increase the engine's braking
effect, the drive wheels could lose their grip.
There is an increased danger of skidding and
accidents.
Do not shift down for additional engine
braking on a slippery road surface.
Downhill gradients !
On long and steep gradients, you must
reduce the load on the brakes by shifting
early to a lower gear. This allows you to take
advantage of the engine braking effect and
helps avoid overheating and excessive
wear of the brakes.
When you take advantage of the engine
braking effect, a drive wheel may not turn
for some time, e.g. on a slippery road
surface. This could cause damage to the
drive train. This type of damage is not
covered by the Mercedes-Benz warranty.
Heavy and light loads G
WARNING
If you rest your foot on the brake pedal while
driving, the braking system can overheat. This
increases the stopping distance and can even
cause the braking system to fail. There is a
risk of an accident.
Never use the brake pedal as a footrest. Never
depress the brake pedal and the accelerator
pedal at the same time.
! Depressing the brake pedal constantly
results in excessive and premature wear to
the brake pads.
If the brakes have been subjected to a heavy
load, do not stop the vehicle immediately.
Drive on for a short while.T his allows the
airflow to cool the brakes more quickly. 152
