G WARNING
If the windshield wipers begin to move while
you are changing the wiper blades, you could
be trapped by the wiper arm. There is a risk of
injury.
Always switch off the windshield wipers and
ignition before changing the wiper blades.
! 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 wind-
shield.
Never fold a windshield wiper arm without a
wiper blade back onto the windshield.
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 spe-
cialist workshop.

Air vents
Important safety notes
G WARNING
Very hot or very cold air can flow from the air
vents. This could result in burns or frostbite in
the immediate vicinity of the air vents. There
is a risk of injury.
Make sure that all vehicle occupants always
maintain a sufficient distance to the air out-
lets. If necessary, redirect the airflow to
another area of the vehicle interior.
In order to ensure the direct flow of fresh air
through the air vents into the vehicle interior,
please observe the following notes: R
keep the air inlet between the windshield and
the hood free of blockages, such as ice, snow
or leaves. R
never cover the air vents or air intake grilles in
the vehicle interior.

Start-off assist (except Mercedes-
AMG vehicles)
Important safety notes
G WARNING
If you use start-off assist, individual wheels
may start to spin and the vehicle may skid. If
ESP ®
is deactivated, there is a greater danger
of skidding and having an accident. Make sure
that no persons or obstacles are in the vicinity
of the vehicle.
Start-off assist enables optimum acceleration
from a standstill. For this, a suitably high-grip
road surface is required, along with the tires and
vehicle being in proper operating condition.
Do not activate start-off assist on public roads.
Observe the safety notes on driving safety sys-
tems ( Y
page 60).
Be sure to read the safety notes and information
on ESP ®
( Y
page 63).

RACE START (Mercedes-AMG vehi-
cles)
Important safety notes
i RACE START must not be used on normal
roads. RACE START must only be activated
and used on dedicated road circuits, outside
of public road use.
i RACE START is only available in
Mercedes ‑ AMG vehicles.
G WARNING
If you use RACE START, individual tires may
start to spin and the vehicle could skid.
Depending on the selected ESP ®
mode, there
is an increased risk of skidding and having an
accident. Make sure that no persons, animals
or obstacles are within range of the vehicle.
RACE START enables optimal acceleration from
a standing start. For this, a suitably high-grip
road surface is required, along with the tires and
vehicle being in proper operating condition.
i Observe the safety notes on driving safety
systems ( Y
page 60).
Be sure to read the safety notes and informa-
tion on ESP ®
( Y
page 63).
Conditions for activation

Coolant temperature gauge
G WARNING
Opening the hood when the engine is over-
heated or when there is a fire in the engine
compartment could expose you to hot gases
or other service products. There is a risk of
injury.
Let an overheated engine cool down before
opening the hood. If there is a fire in the
engine compartment, keep the hood closed
and contact the fire department.
! A display message is shown if the coolant
temperature is too high.
If the coolant temperature is over 248 ‡
(120 †), do not continue driving. The engine
will otherwise be damaged.
The coolant temperature gage is in the instru-
ment cluster on the right-hand side ( Y
page 32).
The H marking in the coolant temperature gauge
corresponds to a coolant temperature of
approximately 248 ‡ (120 †).
Under normal operating conditions and at the
correct coolant level, the coolant temperature
gauge may rise to the H marking. Operating the on-board computer

G WARNIN G
During charging and jump-starting , explosive
gase s can escape from th e battery. There is a
ris k of an explosion .
Particularly avoi d fire, open flames, creating
sparks and smoking. Ensur e there is sufficien t
ventilation while charging and jump-starting .
Do no t lean ove r a battery.

G WARNIN G
A discharged battery can freez e at tempera-
tures belo w freezing point. When jump-start - ing th e vehicl e or charging th e battery, gase s
can escape from th e battery. There is a ris k of
an explosion .
Allow th e frozen battery to thaw out before
charging it or jump-starting .
! Only use battery chargers wit h a maximum
charging voltag e of 14.8 V.
