Important safety notes G
WARNING
For safety reasons, switch off the wipers and
remove the SmartKey from

the starter switch
before replacing a wiper blade. Otherwise, the
wiper motor could suddenly turn on and cause
injury.
! To avoid damaging the wiper blades,
make sure that you touch only the wiper
arm of the wiper. !
Never open the hood
if a windshield wiper
arm has been folded away from the
windshield.
Never fold a windshield wiper arm without
a wiper blade back onto the windshield/
rear window.
Hold the windshield wiper arm firmly when
you change the wiper blade. If you release
the windshield wiper arm without a wiper
blade and it falls onto the windshield, the
windshield may be damaged by the force of
the impact.
Mercedes-Benz recommends that you have
the wiper blades changed at a qualified
specialist workshop.

Important safety notes
G
WARNING
When operating the climate control, the air
that enters the passenger compartment
through the air vents can be very hot or very
cold (depending on the

set temperature). This
could cause burns or frostbite to unprotected
skin in the immediate area of the air vents. 134

Make sure that all objects in the vehicle are
stowed correctly, and that they cannot enter
the driver's footwell. Install the floormats
securely and as specified in order to ensure
sufficient clearance for
the
pedals. Do not use
loose floormats. G
WARNING
Unsuitable footwear can hinder correct usage
of the pedals, e.g.:
R shoes with thick soles
R shoes with high heels
R slippers
There is a risk of an accident.
Wear suitable footwear to ensure correct
usage of the pedals. G
WARNING
If you switch off the ignition while driving,
safety-relevant functions are only available
with limitations, or not

at all. This could affect,
for example, the power steering and the brake
boosting effect. You will require considerably
more effort to steer and brake. There is a risk
of an accident.
Do not switch off the ignition while driving. G
WARNING
If the parking brake has not been fully
released when driving, the

parking brake can:
R overheat and cause a fire
R lose its hold function.
There is a risk of fire and an accident. Release
the parking brake fully before driving off.
! Warm up the engine quickly. Do not use
the engine's full performance until it has
reached operating temperature.
Only shift the automatic transmission to
the desired drive position when the vehicle
is stationary.
Where possible, avoid spinning the drive
wheels when pulling away on slippery
roads. You could otherwise damage the
drive train. !
Avoid high engine speeds when the
engine is cold. The engine's service life
could otherwise be significantly

shortened.
Do not use the engine's full performance
until it has reached operating temperature.
! AMG vehicles: at low engine oil
temperatures below 68 ‡ (+20 †), the
maximum engine speed is restricted in
order to protect the engine. To protect the
engine and maintain smooth engine
operation, avoid driving at full throttle when
the engine is cold. SmartKey positions

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
without sufficient ventilation. G
WARNING
Inhalation of exhaust gas is hazardous to your
health. All exhaust gas contains carbon
monoxide (CO), and inhaling it can cause
unconsciousness and possible death.
Do not run the

engine in confined areas (such
as a garage) which are not properly ventilated.
If you think that exhaust gas fumes are
entering the vehicle while driving, have the
cause determined and corrected
immediately. If you must drive under these
conditions, drive only with at least one
window fully open at all times.
! Do not depress the accelerator pedal
when starting the engine. Starting procedure X
Shift the automatic transmission to
position P.
The transmission position display in the
multifunction display shows P.
i For further information about the
automatic transmission, see
(Y page 145).
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 in the ignition lock to
position 3 (Y page 139) 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 139) 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 D or
R, the vehicle could

pull away suddenly. There
is a risk of an accident.
When engaging transmission position D or R,
always firmly depress the brake pedal and do
not simultaneously accelerate.
! Only shift the automatic transmission to
reverse gear R or park position P when the
vehicle is stationary. Otherwise, the
automatic 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. 140
