R the position of the accelerator pedal
R the road speed 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 AMG vehicles When shifting down, the double-clutch func-
tion is active regardless of the currently selec-
ted drive program. The double-clutch function
reduces load change reactions and is condu-
cive to a sporty driving style. The sound gen-
erated by the double-clutch function depends
on the drive program selected.

Switching off the engine
Important safety notes G
Risk of accident
If the engine is not running, there is no power
assistance for the steering and brakes. Steer-
ing and braking then requires significantly
greater effort.
As a result, you might lose control of the vehi-
cle, cause an accident and injure yourself and
others.
Therefore, do not switch off the engine while
you are driving.

need to apply the brakes yourself.
X Let go of the multifunction steering wheel.
X Back up the vehicle, being ready to brake
at all times. When reversing, do not exceed
a speed of approximately 10 km/h; other-
wise, Active Parking Assist will be deacti-

Environmental note
When topping up the oil, take care not to spill
any. If oil enters the soil or waterways, it is
harmful to the environment. Example: engine oil cap
X
Turn cap :anti-clockwise and remove it.
X Top up with the amount of oil required.
Fill carefully to the maximum mark on the oil
dipstick.
i Depending on the engine, the difference
between the minimum mark and the maxi-
mum mark is approximately 1.5 – 2 litres.
! Do not add too much oil. If the oil level is
above the "max" mark on the dipstick, too
much oil has been added. This can lead to
damage to the engine or the catalytic con-
verter. Have excess oil siphoned off.
Further information on engine oil
(Y page 320).
X Replace cap :on the filler neck and
tighten clockwise.
Ensure that the cap locks into place

Risk of injury
The cooling system is pressurised. Therefore,
only unscrew the cap once the engine has
cooled down. The coolant temperature gauge
must display less than 70 †.Otherwise, you
could be scalded if hot coolant escapes. X

Environmental note
Dispose of empty packaging and cleaning
cloths in an environmentally responsible man-
ner.
! Do not park up the vehicle for an extended
period straight after cleaning it, particularly
after having cleaned the wheels with wheel
cleaner. Wheel cleaners could cause
increased corrosion of the brake discs and
brake pads/linings. For this reason, you
should drive for a few minutes after clean-
ing. Braking heats the brake discs and
brake pads, thus drying them. The vehicle
can then be parked up. Care of the exterior
Automatic car wash G
Risk of accident
Braking efficiency is reduced after washing
the vehicle. This could cause an accident. For
this reason, following a car wash, drive with
particular care until the brakes are dry. G
Risk of accident
The vehicle is braked when the HOLD function
or DISTRONIC PLUS is activated. Therefore,
deactivate the HOLD function and DISTRONIC
PLUS before the vehicle is washed in an auto-
matic car wash.
You can wash the vehicle in an automatic car
wash from the very start.
If the vehicle is very dirty, pre-wash it before
cleaning it in an automatic car wash.
! In car washes with a towing mechanism,
make sure that the automatic transmission
is in transmission position N, otherwise the
vehicle could be damaged.
R Vehicles with a key:
do not remove the key from the ignition
lock. Do not open the driver's door or front-passenger door when the engine is
switched off. Otherwise, the automatic
transmission selects park position
P
automatically and locks the wheels. You
can prevent this by shifting the auto-
matic transmission to Nbeforehand.
R Vehicles with KEYLESS-GO:
do not open the driver's door or front-
passenger door when the engine is
switched off. Otherwise, the automatic
transmission selects park position P
automatically and locks the wheels.
Observe the following to make sure that the
automatic transmission stays in position N:
X Make sure the vehicle is stationary and the
ignition is switched off.
X Turn the key to position 2(Y page 129) in
the ignition lock.
Use the key instead of the Start/Stop but-
ton on vehicles with KEYLESS-GO.
X Depress and hold the brake pedal.
X Shift the automatic transmission to posi-
tion N.
X Release the brake pedal.
X Release the parking brake.
X Switch off the ignition and leave the key in
the ignition lock.
! Make sure that:
R the side windows and sliding sunroof are
closed completely.
R the blower for the ventilation/heating is
switched off (OFF button is depressed).
R the windscreen wiper switch is at posi-
tion 0.
The vehicle could otherwise be damaged.
After using an automatic car wash, wipe off
wax from the windscreen and the wiper
blades. This will prevent smears and reduce
wiping noises caused by residue on the wind-
screen. Care
