Slippery road surfaces
G
WARNING
If you shift down on aslippery road surface in
an attempt to increase the engine's braking
effect,t he drive wheels could lose their grip.
This increases the risk of skidding and having
an accident.
Do not shift down for additional engine brak-
ing on aslippery road surface.
If the vehicle threaten stoskid or cannot be
stopped when moving at low speed:
X Move the transmission to position N.
X Try to bring the vehicle under control by
using corrective steering.
You should drive particularly carefully on slip-
pery road surfaces. Avoid sudden accelera-
tion, steering and braking manoeuvres.

snow chains, see (Y page 331). Driving systems
Cruise control
Important safety notes G
WARNING
Do not change down for additional engine
braking on aslippery road surface. This could
cause the drive wheels to lose their grip and
the vehicle could skid. G
WARNING
Cruise control cannot take account of road
and traffic conditions.
Always pay attention to traffic conditions
even when cruise control is activated.
Cruise control is only an aid designed to assist
driving. You are responsible for the vehicle's
speed and for braking in good time. G
WARNING
Do not use cruise control
R in traffic condition sthat do not allow you to
drive at aconstant speed (e.g. heavy traffic
or winding roads). You may otherwise
cause an accident.
R on slippery roads. The drive wheels may
lose their grip when braking or accelerating
and the vehicle may skid.
R when there is low visibility, e.g. due to fog,
heavy rain or snow.
General notes Cruise control maintains
aconstant road
speed for you. It brakes automatically in order
to avoid exceeding the set speed. On long and
steep downhill gradients, especially if the
vehicle is laden, you must select shift range
1, 2or 3in good time. By doing so, you will
make use of the braking effect of the engine.
This relieves the load on the brake system and
preventst he brakes from overheating and
wearing too quickly.
Use cruise control only if road and traffic con-
ditions make it appropriate to maintain a
steady speed for aprolonged period. You can
store any road speed above 30 km/h.

Important safety notes G
WARNING
RACE START is only available when SPORT
handling mode is activated. SPORT handling
mode will only be able to stabilise the vehicle
to alimited degree if the vehicle start stoskid
or aw heel start stospin. The vehicle is there-
fore harder to control at the threshold range.
You could lose control of the vehicle and
cause an accident.
RACE START should only be used on closed
off circuits. Always adapt your driving style to
suit the prevailing road and weather condi-
tions.
i RACE START is only available in AMG vehi-
cles.
RACE START enables optimum acceleration
from astanding start .The precondition for
this is asuitable high-grip road surface.
Activation conditions You can activat
eRACE START if:
R the doors are closed.
R the engine is running and it has reached an
operatin gtemperature of approximately
80 †. This is the case when the engine oil
temperature in the multifunction display
stops flashing.

PARKTRONIC
Important safety notes G
WARNING
PARKTRONIC is only an aid and may not
detect all obstacles. It is not asubstitute for
attentive driving.
You are always responsible for safety and
must continue to pay attention to your imme-
diate surroundings when parking and
manoeuvring. You could otherwise endanger
yourself and others. G
WARNING
Make sure that no persons or animals are in
the manoeuvring range. Otherwise, they
could be injured.
PARKTRONIC is an electronic parking aid with
ultrasonic sensors. It indicates visuallya nd
audibly the distance between your vehicle
and an object.
PARKTRONIC is activated automatically if
you:
R switch on the ignition
R shift the transmission to position D,Ror N
R release the parking brake
PARKTRONIC is deactivated at speeds above
18 km/h. It is reactivated at lower speeds.
PARKTRONIC monitorst he area around your
vehicle using six sensors in the front bumper
and four sensors in the rear bumper.
Range of the sensors General notes
!
When parking, pay particular attention to
objectsa bove or below the sensors, such
as flower pots or trailer drawbars. PARK-
TRONIC does not detect such objectsw hen
they are in the immediate vicinity of the
vehicle. You could damage the vehicle or
the objects.
The sensors may not detect snow and
objectsw hich absorb ultrasonic sources. Ultrasonic sources, such as an automatic
car wash,
alorry's compressed-air brakes
or ap neumatic drill, could cause PARK-
TRONIC to malfunction.
PARKTRONIC may not function correctly on
uneven terrain. :
Example: sensors in the front bumper,
left-han dside
The sensors must be free of dirt, ice and
slush. Otherwise, they may not function cor-
rectly. Cleant he sensors regularly,t aking
care not to scratchord amage them
