Risk of accident
If, in a critical driving situation, you do not
receive a visual and acoustic warning:
R PRE-SAFE ®
Brake did not detect the risk of
a collision
R PRE-SAFE ®
Brake is switched off
R PRE-SAFE ®
Brake has failed
You must then brake to avoid a collision.
X To activate: activate PRE-SAFE ®
Brake in
the on-board computer (Y page 130).
The Ä symbol appears in the lower
multi-function display, as long as the HOLD
function is not activated (Y page 151).
On vehicles with parking guidance*, drive
range Pmust be engaged for the symbol to
be displayed.
The radar sensors are automatically deacti-
vated in the vicinity of radio telescope facili-
ties (Y page 362).
For PRE-SAFE ®
Brake to assist you when driv-
ing, the radar sensor system must be
switched on and operational.
PRE-SAFE ®
Brake does not always detect
complex traffic situations properly. You can
terminate the braking action of PRE-SAFE ®
Brake in a non-critical driving situation at any
time if:
R an acoustic and visual warning occurs
R the vehicle brakes
To end this you can either depress the accel-
erator pedal further, activate kickdown or
release the brake pedal.
The braking action of PRE-SAFE ®
Brake is
ended automatically if:
R you manoeuvre to avoid the obstacle.
R you drive slower than approximately
15 km/h.
R there is no longer an obstacle detected in
front of your vehicle.
R there is no longer any danger of a collision. Following a collision or crash-related damage
to the front end of the vehicle, have the con-
figuration and operation of the radar sensors
checked. Choose a qualified specialist work-
shop for this which has the necessary spe-
cialist knowledge and tools for the work
required. Mercedes-Benz recommends that
you use a Mercedes-Benz Service Centre for
this purpose.

rier
R On rare occasions: road users that have
lights may be recognised too late or not at
all.
The automatic main-beam headlamps will not
be deactivated, or they may be activated
despite road users travelling in front of, or
approaching, the vehicle.
Thus, you could cause an accident and injure
yourself and others. Always observe traffic
conditions and, if necessary, dip the lights
manually.

Intelligent Light System* (bi-xenon
headlamps*) The Intelligent Light System is a system which
adjusts the headlamps automatically to suit
the prevailing driving and weather conditions.
The bi-xenon headlamps offer enhanced func-
tions to improve illumination of the road sur-
face, e.g. depending on the vehicle speed or
weather conditions. The system includes the
active light function, cornering light function,
motorway mode and extended range fog-
lamps. The system is only active when it is
dark.
You can activate or deactivate the "Intelligent
Light System" using the on-board computer
(Y page 132).
Active light function The active light function is a system that
moves the headlamps according to the steer-
ing movements of the front wheels. In this way, relevant areas remain illuminated while
driving. This allows you to recognise pedes-
trians, cyclists and animals.
Cornering light function
The cornering light function improves the illu-
mination of the road surface in the broad
direction you are turning, e.g. making it easier
to see in tight corners. It can only be activated
when the dipped-beam headlamps are
switched on.
Active:
R
if you are driving at speeds below
40 km/h, the cornering light function is
activated either by the turn signal or by the
steering wheel being turned.
R if you are driving at speeds between
40 km/h and 70 km/h, the cornering light
function is activated by the steering wheel
being turned.
Not active: if you are driving at speeds above
70 km/h or you switch off the turn signal or
move the steering wheel to the straight-
ahead position.
The cornering lamp may remain lit for a short
time, but is automatically switched off after
no more than three minutes. Lights

Parking
G
Risk of accident
Only remove the key from the ignition lock
when the vehicle is stationary, as you cannot
steer the vehicle with the key removed.
Never leave children unsupervised in the vehi-
cle. They could release the parking brake. This
could lead to a serious or fatal accident. G
Risk of fire
Make sure that the exhaust system does not
under any circumstances come into contact
with easily ignitable material such as dry grass
or petrol. Otherwise, the flammable material
may ignite and set the vehicle on fire.
To ensure that the vehicle is secured against
rolling away unintentionally:
R the parking brake must be applied
R on vehicles with manual transmission,
engage first gear or reverse gear
R on vehicles with automatic transmission*,
the transmission must be in position Pand
the key must be removed from the ignition
lock
R on steep uphill or downhill gradients, turn
the front wheels towards the kerb
Parking brake X
To apply: depress parking brake ;firmly.

X Pull release handle :.
The J warning lamp in the instrument
cluster goes out. Switching off the engine
G
Risk of accident
If the engine is not running, there is no power
assistance for the steering and brakes. Steer-
ing and braking will then require significantly
greater effort.
As a result, you might lose control of the vehi-
cle, cause an accident and injure yourself and
others.
Therefore, do not switch off the engine while
you are driving.
Vehicles with manual transmission X
Shift to either first or reverse gear.
X Turn the key to position 0(Y page 75) in
the ignition lock and remove it.
The immobiliser is activated.

Downshifting
G
Risk of accident
Do not shift down to brake on a slippery road
surface. This could cause the drive wheels to
lose their grip, and the vehicle could skid.
X Pull the left-hand paddle ( Ypage 114).
The automatic transmission shifts down to
the next gear.
i For maximum acceleration, pull the left-
hand steering wheel gearshift paddle until
the transmission selects the optimum gear
for the current speed.
Kickdown
i On vehicles with AMG engines, it is not
possible to use kickdown in manual drive
program M. 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, then no display messages can be
shown.
You will not then be able to see information
about the vehicle status, such as speed and
outside temperature, warning and indicator
lamps, display messages or the failure of sys-
tems. The vehicle’s handling characteristics
may be affected. Adapt 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 right-hand side.
Under normal operating conditions and with
the specified coolant level, the coolant tem-
perature may rise to 120 †. The coolant tem-
perature may rise to the top end of the scale
at high outside temperatures and on long
uphill stretches. Speedometer with segments
The segments in the speedometer indicate
which speed range is available.
Cruise control mode:
The segments light up from the stored speed
to the maximum speed.
Variable Speedtronic mode:
The segments light up from the start of the
scale to the selected limit speed.
Distronic Plus* mode:
One or two segments around the stored
speed light up. 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
At temperatures just above freezing point, the
road could be icy, particularly in wooded areas
or on bridges. The vehicle could start skidding
if you fail to adapt your driving style. You
should therefore always adapt your driving
style and speed to suit the weather condi-
tions. Inst
