X
Pull the left-hand steering wheel gearshift
paddle (Y page 210).
The automatic transmission shifts down to
the next gear.
i If you slow down or stop without shifting
down, the automatic transmission auto-
matically shifts down.
Kickdown
i Vehicles with an AMG engine: it is not
possible to use kickdown in manual drive
program M.
You can also use kickdown for maximum
acceleration in manual drive program M.
X Depress the accelerator pedal beyond the
pressure point.
The transmission shifts to a lower gear
depending on the engine speed.
X Shift back up once the desired speed is
reached.
i Vehicles without an AMG engine: if you
apply full throttle, the automatic transmis-
sion shifts up to the next gear at maximum
engine speed. This prevents the engine
from overrevving. Instrument cluster
Points to remember
You will find an illustration of the instrument
cluster in the "At a glance" section
(Y page 27). G
Risk of accident
If the instrument cluster or the multi-function
display fails, it can no longer show any display
messages.
You will not then be able to see information
about the vehicle status, such as speed, out-
side temperature, warning and indicator
lamps, display messages or the failure of sys-
tems. Handling characteristics may be affec-
ted. Adjust your driving style and speed
accordingly. Immediately consult a qualified specialist
workshop which has the necessary specialist
knowledge and tools to carry out the work
required. Mercedes-Benz recommends that
you use a Mercedes-Benz Service Centre for
this purpose. In particular, work relevant to
safety or on safety-related systems must be
carried out at a qualified specialist workshop. Coolant temperature display
The coolant temperature gauge is in the
instrument cluster on the left-hand side.
Under normal operating conditions and with
the specified coolant level, the coolant tem-
perature may rise to 120 †. Rev counter
The red band in the rev counter indicates the
engine's overrevving range. The fuel supply is
interrupted to protect the engine when the
red band is reached.
! Do not drive in the overrevving range.
Doing so will damage the engine. Outside temperature display
G
Risk of accident
If the temperature is slightly above freezing,
the road may be icy, especially in wooded
areas or on bridges. If you do not adjust your
driving style, the vehicle may start to skid. For
this reason, you should always adjust your
driving style and speed to the weather condi-
tions.
Changes in the outside temperature are dis-
played after a short delay. 212

Overview of driving systems
The vehicle's driving systems are described
on the following pages:
R cruise control, Distronic*, Distronic Plus*
and Speedtronic, which are used to control
the speed of the vehicle
R HOLD, which makes pulling away easier,
particularly on steep uphill gradients
R AIRMATIC* and Active Body Control (ABC),
which is used to adjust the vehicle’s sus-
pension system
R 4MATIC* (permanent four-wheel drive), for
optimum traction
R PARKTRONIC and Park Assist*, which
assist you when parking
R reversing camera*, which assists you when
parking
R Night View Assist*, which assists you when
driving in the dark
R Parking Guidance*, which assists you when
looking for a parking space and assists you
when parking
R Blind Spot Assist*, which assists you when
changing lanes
The ABS, BAS, BAS PLUS*, adaptive brake
lights, ESP ®
, EBV, ADAPTIVE BRAKE, distance
warning function* and PRE-SAFE ®
Brake*
driving systems are described in the "Driving
safety systems" section (Y page 48).Cruise control
Cruise control maintains a constant 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,
which relieves the load on the brake system
and prevents the brakes from overheating
and wearing too quickly. G
Risk of accident
Do not change down for additional engine
braking on a slippery road surface. This could
cause the drive wheels to lose their grip and
the vehicle could skid.
Use cruise control only if road and traffic con-
ditions make it appropriate to maintain a
steady speed for a prolonged period. You can
store any road speed above 30 km/h. G
Risk of accident
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
Risk of accident
Do not use cruise control:
R in road and traffic conditions which do not
allow you to maintain a constant speed (e.g.
heavy traffic or winding roads). You could
otherwise cause an accident.
R on slippery roads. Braking or accelerating
could cause the drive wheels to lose trac-
tion and the vehicle could then skid.
R when there is poor visibility, e.g. due to fog,
heavy rain or snow

speed.
X Briefly press the cruise control lever
up : or down ?to the pressure point.
X Remove your foot from the accelerator
pedal.
Cruise control is activated. The vehicle
automatically maintains the stored speed.
i Cruise control may be unable to maintain
the stored speed on uphill gradients. The
stored speed is resumed when the gradient
evens out. Cruise control maintains the
stored speed on downhill gradients by
automatically applying the brakes.
Storing the current speed or calling up
the last stored speed G
Risk of accident
Only select a stored speed if you know what
that speed is and whether it is suitable for the
current situation. Otherwise, sudden acceler-
ation or braking could endanger you or others. 228

Risk of accident
Do not change down for additional engine
braking on a slippery road surface. This could
cause the drive wheels to lose their grip and
the vehicle could skid. G
Risk of accident
Distronic is only an aid designed to assist
driving. The driver remains fully responsible
for the vehicle's distance from other vehicles,
the vehicle's speed and for braking in good
time.
Distronic does not react to:
R pedestrians
R stationary obstacles on the road, e.g. sta-
tionary or parked vehicles
R oncoming and crossing traffic
Distronic may not detect narrow vehicles driv-
ing in front, e.g. motorcycles, or vehicles driv-
ing on a different line. Therefore, always pay
attention to traffic conditions even when Dis-
tronic is activated. Otherwise, you may fail to
recognise dangers in time, could cause an
accident and injure yourself and others.
If a slower-moving vehicle is detected in front,
Distronic causes your vehicle to brake and
maintain the preset distance to the vehicle in
front that you have set. G
Risk of accident
Distronic cannot take account of road and
traffic conditions. Deactivate, or do not acti-
vate, Distronic if it does not detect the vehicle
in front, or if it no longer detects it. This is
especially the case:
R before corners
R in filter lanes
R when changing to a lane with faster moving
traffic
R in complex driving situations or where the
lanes are diverted, e.g. at roadworks on a
motorway
Otherwise, Distronic maintains the current
speed or accelerates to the set speed.
Distronic cannot take account of weather
conditions. Deactivate, or do not activate,
Distronic:
R if the roads are slippery, snow-covered or
icy. The wheels could lose their grip when
braking or accelerating. The vehicle could
start to skid.
R if the sensors are dirty or there is poor vis-
ibility, e.g. due to snow, rain or fog. Dis-
tance control may be impaired.
Always pay attention to traffic conditions
even when Distronic is activated. Otherwise,
you may fail to recognise dangers in time,
could cause an accident and injure yourself
and others.
If there is no vehicle in front, Distronic oper-
ates in the same way as cruise control. Dis-
tronic functions in the 30 km/h to
200 km/h range. G
Risk of accident
Distronic brakes your vehicle at a maximum
of 2 m/s 2
, depending on its speed. This cor-
responds to approximately 20% of your vehi-
cle's maximum braking power. You must also
apply the brakes yourself if this braking power
is not sufficient. 230

road and traffic conditions in which you must
be particularly attentive. In such situations,
brake if necessary. Distronic is then deacti-
vated.
Cornering, entering and exiting a bend
The ability of Distronic to detect vehicles
when cornering is limited. Your vehicle may
brake unexpectedly or too late.
Vehicles travelling on a different line
Distronic may not detect vehicles travelling
on a different line. The distance to the vehicle
in front will be too short.234
