Due to the nature of the system, particularly
complicated but non-critical driving conditions
may also cause Brake Assist to intervene.
If Adaptive Brake Assist is not available due to a malfunction in the radar sensor system, the
brake system remains available with full brake
boosting effect and BAS. Adaptive brake lights
i Observe the "Important safety notes" sec-
tion (Y page 62).
If you brake sharply from a speed of more than
50 km/h or if braking is assisted by BAS or
Brake Assist with Cross-Traffic Assist, the brake lamps flash rapidly. In this way, traffic travelling
behind you is warned in an even more noticeable
manner.
If you brake sharply from a speed of more than
70 km/h to a standstill, the hazard warning
lamps are activated automatically. If the brakes
are applied again, the brake lamps light up con- tinuously. The hazard warning lamps switch off
automatically if you travel faster than 10 km/h. You can also switch off the hazard warning
lamps using the hazard warning button
(Y page 115). ESP
®
(Electronic Stability Program)
General notes i
Observe the "Important safety notes" sec-
tion (Y page 62).
ESP ®
monitors driving stability and traction, i.e.
power transmission between the tyres and the
road surface.
If ESP ®
detects that the vehicle is deviating from
the direction desired by the driver, one or more wheels are braked to stabilise the vehicle. The
engine output is also modified to keep the vehi-cle on the desired course within physical limits.
ESP ®
assists the driver when pulling away on
wet or slippery roads. ESP ®
can also stabilise
the vehicle during braking.
ETS (Electronic Traction System) i
Observe the "Important safety notes" sec-
tion (Y page 62). ETS traction control is part of ESP
®
.
ETS brakes the drive wheels individually if they
spin. This enables you to pull away and acceler- ate on slippery surfaces, e.g. if the road surface
is slippery on one side. In addition, more drive
torque is transferred to the wheel or wheels with traction.
ETS remains active when you deactivate ESP ®
.
i Mercedes-AMG vehicles:
your vehicle may
be equipped with 20-inch tyres on the rear
axle. If replaced with 19-inch tyres, ETS may
intervene noticeably sooner for the first few
kilometres. After approximately 10 km ETS
will function as usual again. Information on
the dimensions and types of wheels and tyres
for your vehicle can be found under "Wheel/
tyre combinations" (Y page 317).
Important safety notes G
WARNING
If ESP ®
is malfunctioning, ESP ®
is unable to
stabilise the vehicle. In addition, other driving
safety systems are switched off. This increa-
ses the risk of skidding and an accident.
Drive on carefully. Have ESP ®
checked at a
qualified specialist workshop.
When towing away your vehicle with the rear
axle raised, observe the notes on ESP ®
(Y page 300).
If the å ESP®
OFF warning lamp lights up
continuously, then ESP ®
is deactivated.
If the ÷ ESP®
warning lamp and the å
ESP ®
OFF warning lamp are lit continuously,
ESP ®
is not available due to a malfunction.
Observe the information on warning lamps
(Y page 246) and display messages which may
be shown in the instrument cluster
(Y page 217).
i Only use wheels with the recommended tyre
sizes. Only then will ESP ®
function properly.

ing:
R the vehicle exhibits particularly economical
driving characteristics.
R the vehicle pulls away more gently in forward
and reverse gears unless the accelerator
pedal is depressed fully.
R optimal fuel consumption resulting from the
automatic transmission shifting up sooner.
The vehicle is driven in the low engine speed
range and the wheels are less likely to spin.
R the suspension exhibits comfortable damping
settings.
R the steering exhibits a comfortable steering
curve.
R during deceleration, the engine is disconnec-
ted from the drive train. The vehicle uses
kinetic energy and consumes less fuel (gliding
mode).
R ESP ®
provides the optimum compromise
between traction and stability. Further infor-
mation on ESP ®
(Y page 67).
Vehicles with Active Body Control: drive
program CURVE

Mercedes-AMG vehicles Drive program RACE
Drive program RACEis characterised by the fol-
lowing:
R the vehicle exhibits driving characteristics
suitable for the racetrack.
R all vehicle systems are set for maximum
sportiness.
R the gearshift recommendation gives you
information for slowly warming up the drive
assemblies and for adopting a fuel-efficient
driving style (Y page 147). You can follow the
gearshift recommendations at all times and
change gear accordingly using the steering
wheel gearshift paddles. On the basis of the
gearshift recommendation, using the steering
wheel gearshift paddles, you can optimise the drive train and engine operating mode at any
time.
R if you have selected a gear manually, this will
be maintained until the vehicle speed signifi-
cantly increases or decreases.
R the vehicle pulls away in first gear.
R the automatic transmission shifts up later. As
a result of the later automatic transmission
shift points, the fuel consumption may be
higher.
R the suspension exhibits particularly firm

Automatic transmissionDriving and parking

must be positioned vertically, directly under
the jacking point of the vehicle.
Observe the following when raising the vehicle:
R only use the vehicle-specific jack that has
been tested and approved by Mercedes-Benz
to raise the vehicle. If the jack is used incor-
rectly, it could tip over while the vehicle is
raised.
R the jack is designed only to raise and hold the
vehicle for a short time while a wheel is being
changed. It is not permissible to use it to per- form maintenance work under the vehicle.
R avoid changing the wheel on uphill and down-
hill slopes.
R before raising the vehicle, safeguard it from
rolling away by applying the parking brake and
positioning wheel chocks. Do not release the parking brake while the vehicle is raised.
R the jack must be placed on a firm, flat and
non-slip surface. On a loose surface, a large,
flat load-bearing underlay must be used. On a
slippery surface, a non-slip underlay must be
used, e.g. rubber mats.
R do not use wooden blocks or similar objects
as a jack underlay. Otherwise, the jack will not
be able to achieve its load-bearing capacity
due to the restricted height.
R make sure that the distance between the
underside of the tyres and the ground does
not exceed 3 cm.
R never place your hands or feet under the
raised vehicle.
R do not lie under the vehicle.
R do not start the engine when the vehicle is
raised.
R do not open or close a door or the boot lid
when the vehicle is raised.
R make sure that no persons are present in the
vehicle when the vehicle is raised.
