twigs may ignite if they come into contact with hot parts of the exhaust system or exhaust
gas flow. There is arisk of fire.
Park the vehicle so that no flammable mate-
rial can come into contact with hot vehicle
components.Inp articular, do not park on dry
grassland or harvested grain fields. G
WARNING
If you leave children unattended in the vehi-
cle, they may be able to set the vehicle in
motion if, for example, they:
R release the parking brake
R shift the automatic transmission out of park
position Por shift manual transmission into
neutral
R start the engine
In addition, they may operate vehicle equip-
ment and become trapped. There is arisk of
an accident and injury.
When leaving the vehicle, alway stake the key
with you and lock the vehicle. Never leave
children unattended in the vehicle.
! Always secure the vehicle correctly against
rolling away.O therwise, the vehicle or its driv-
etrain could be damaged. 172
ParkingDriving and parking

To ensure that the vehicle is safeguarded
against rolling away unintentionally:
R the electric parking brake must be applied
R on vehicles with manual transmission, engage
1st gear or reverse gear

High-performance and ceramic brakes
(Mercedes-AMG vehicles) The AMG brake systems are designed for heavy
loads. This may lea dtonoise when braking. This
is dependent on:
R speed
R braking force
R environmental conditions, such as tempera-
ture and humidity
The wea rofindividua lbrake system compo-
nents such as the brake pads/linings or brake
discs depends on individuald riving style and
operating conditions.
For this reason, it is impossible to state amile-
age (service life )that wil lbevalidu nder all cir-
cumstances. An aggressive driving style will
lea dtoh igh wear. You can obtai nmore infor-
mation on this from aqualified specialist work-
shop.
Brake pads/linings and discs that are either new or have been replaced only achieve optimum
braking effect after severa lhundre dkilometres
of driving. Compensate for the reduced braking
effect by applying greater force to the brake
pedal. Always be aware of this and adapt your
driving and braking accordingly during the run-
ning-in period.
Excessive heavy braking results in correspond-
ingly high brake wear. Observe the brake wear
warning lamp in the instrument cluste rand note
any brake status messages in the multifunction
display .Ifyou regularl ydrive at high speeds, it is
particularly important to have the brake system
checked and maintained regularly. Driving on wetr
oads
Aquaplaning If wate
rhas accumulated to acertain depth on
the road surface, there is adange rofa quaplan-
ing occurring, even if:
R you are driving at low speeds
R the tyres have adequate tread depth
For this reason, drive in the following manner in
the event of heavy rain or in conditions in which aquaplaning can occur:
R lower you rspeed
R avoi dtyre ruts R
avoi dsudden steering movements
R brake carefully
Driving on flooded roads !
Bear in mind that vehicles travelling in front
or in the opposite direction create waves. This may caus ethe maximu mpermissible water
depth to be exceeded.
These notes must be observed under all cir-
cumstances. You coul dotherwise damage
the engine, the electronics or the transmis-
sion.
If you must drive on stretches of road on which
wate rhas collected, please bea rinmind that:
R in the case of standing water, the wate rlevel
must be no higher than the lower edge of the vehicl ebody
R you should drive no faster than walking pace Winter driving
G
WARNING
If you shift downonas lippery road surface in
an attempt to increas ethe engine's braking
effect, the drive wheels coul dlose their grip.
This increases the risk of skidding and having
an accident.
Do not shift dow nfor additiona lengine brak-
ing on aslippery road surface. G
DANGER
If the exhaust pipeisb locked or adequate
ventilation is not possible,p oisonous gases
such as carbon monoxide (CO )may enter the
vehicle. This is the case, e.g. if the vehicle
become strappe dinsnow. There is arisk of
fatal injury.
If you leave the engine or the auxiliary heating
running, make sure the exhaust pipea nd area
around the vehicl eare clea rofsnow. To
ensure an adequate supply of fresh air, open a windo wont he side of the vehicl ethat is not
facing into the wind.
Have you rvehicl ewinterproofed at aqualified
specialist worksho patthe onset of winter. Driving tips

The HOLD function is deactivated.
Ah orn will sound at regular intervals if you turn
off the engine, take off your seat belt or open the driver's door when the HOLD function is activa-ted. The horn alerts you to the fact that the
HOLD function is still activated. If you attempt to

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.
RACE START enables optimum acceleration
from astandin gstart .For this, asuitably high-
grip road surface is required, along with the
tyres and vehicle being in good condition. G
WARNING
If you use RACE START, individual tyres may
get into aspin and the vehicle could skid.
Dependin gonthe 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.
i Observe the safety notes on driving safety
systems (Y page 66).
Be sure to read the safety notes and informa-
tion on ESP ®
(Y page 71).
Activation conditions You can activat
eRACE START if:
R the doors are closed
R the engine is running and it has reached an
operating temperature of approximately
71 †. This is the case when the oil tempera-
ture gauge in the multifunction display is
shown in white.
R the drive program S,S+ orRace is selected
(Y page 154)
R the steerin gwheel is in the straight-ahead
position
R the vehicle is stationary and the brake pedal is
depressed (left foot)
R the transmission is in position D
Activating RACE START i
When manual mode (Y
page 163) is active,
the transmission automatically shifts up to
