General notes The Intelligent Light System is a system that
adjusts the headlamps automatically to suit the
prevailing driving and weather conditions. It offers advanced functions for improved illumi-
nation of the road surface, e.g. depending on the
vehicle speed or weather conditions. The sys-
tem includes the active light function, corneringlight function, motorway mode and extended
range foglamps. The system is only active when it is dark.
You can activate or deactivate the "Intelligent
Light System" function using the on-board com-
puter (Y page 294).
Active light function The active light function is a system that moves
the headlamps according to the steering move-
ments of the front wheels. In this way, relevant
areas remain illuminated while you are driving.
This allows you to recognise pedestrians,
cyclists and animals.
Active: when the lights are switched on.
Vehicles with Lane Keeping Assist: the active
light function evaluates the course of the lane in which you are driving and adjusts the light in
advance.
Cornering light function The cornering light function improves the illu-
mination of the road over a wide angle in the124
Exterior lightingLights and windscreen wipers
direction you are turning, enabling better visi-
bility in tight bends, for example. 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
and switch on the turn signal or turn the steer- ing wheel.
R if you are driving at speeds between 40 km/h
and 70 km/ hand turn the steering wheel.
The cornering light function may remain lit for a
short time, but is automatically switched off
after no more than three minutes.
Cornering light function with roundabout
function:
The cornering light function is activated on both sides before entering a roundabout through an
evaluation of the current GPS position of the
vehicle. It remains active until after the vehicle
has left the roundabout. In this way, pedestrians crossing the road, for example, are illuminated
by your vehicle in good time.
Motorway mode Motorway mode increases the range of the
beam.
Active: if you are driving at a speed above
110 km/h and do not make any large steering
movements for at least 1,000 m or if you are
driving at a speed above 130 km/h.
Not active: if you are driving at speeds below
80 km/h following activation. Extended range foglamps The extended range foglamps reduce the glare
experienced by the driver and improve the illu-
mination of the edge of the carriageway.
Active:
if you are driving at speeds below
70 km/h and you switch on the rear foglamp.
Not active: if, following activation, you are driv-
ing at speeds above 100 km/h or if you switch
off the rear foglamp.
Off-road lights The off-road lights facilitate the early recogni-
tion of objects/obstacles when driving off-road
thanks to a symmetrical, wider and brighter dis-
tribution of light from the dipped-beam head-
lamps.
Active: when driving at speeds no faster than
50 km/h and the off-road program selector
wheel is in position 1 or 2.
Not active: when driving at speeds above
50 km/h.
When the off-road lights are switched on, the
cornering light function is permanently activa-
ted, the active light function is deactivated and
the headlamp range control is set to static
mode. Exterior lighting

WARNING
If you switch off the ignition while driving,
safety-relevant functions are only available
with limitations, or not at all. This could affect, for example, the power steering and the brake
boosting effect. You will require considerably
more effort to steer and brake. There is a risk of an accident.
Do not switch off the ignition while driving. G
WARNING
If the parking brake has not been fully
released when driving, the parking brake can:
R overheat and cause a fire
R lose its hold function.
There is a risk of fire and an accident. Release
the parking brake fully before driving off.
! Do not warm up the engine when the vehicle
is stationary. Drive off immediately. Avoid
high engine speeds and driving at full throttle
until the engine has reached its operating
temperature.
Only shift the automatic transmission to the
desired drive position when the vehicle is sta-
tionary.
Where possible, avoid spinning the drive
wheels when pulling away on slippery roads.
You could otherwise damage the drive train.
! Mercedes-AMG vehicles:
at low engine oil
temperatures (below +20 †), the maximum
engine speed is restricted in order to protect the engine. To protect the engine and main-
tain smooth engine operation, avoid driving at
full throttle when the engine is cold.

i If the key does not belong to the vehicle, it
can still be turned in the ignition lock. How-
ever, the ignition will not be switched on. The
engine cannot be started.
KEYLESS-GO General notes
Vehicles with KEYLESS-GO are equipped with a
key featuring an integrated KEYLESS-GO func-
tion and a detachable Start/Stop button.
A check which periodically establishes a radio
connection between the vehicle and the key
determines whether a valid key is in the vehicle. This occurs, for example, when starting the
engine.
When you insert the Start/Stop button into the
ignition lock, the system needs approximately
two seconds recognition time. You can then use the Start/Stop button.
Pressing the Start/Stop button several times in
succession corresponds to the different key
positions in the ignition lock. This is only the
case if you are not depressing the brake pedal.
If you depress the brake pedal and press the
Start/Stop button, the engine starts immedi-
ately. 158
