Possible causes/consequences and
M
MSolutions The steering wheel heat-
ing has switched itself
off prematurely or can-
not be switched on. The on-board voltage is too low because too many electrical consum-
ers are switched on.
X Switch off electrical consumers that you do not need, such as the
rear window heating or interior lighting. EASY-ENTRY/EXIT feature

Memory functionSeats, steering wheel and mirrors
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 246).
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.
Vehicles with drive program S+(Sport Plus): the
active light function swings the headlamps
inwards and outwards once the drive program is activated. This shows that the sporty light set-
ting is activated. The dynamism of the active
light function is increased. Cornering light function The cornering light function improves the illu-
mination of the road over a wide angle in the
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/h and 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.

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. Key positions

3 To start the vehicle
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.
Start/Stop button General notes
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.
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. 146
