The hazard warning lamps switch on auto-
matically if:
R an airbag is deployed or
R the vehicle decelerates rapidly from a
speed of above 70 km/h and comes to a
standstill
The hazard warning lamps switch off auto-
matically if the vehicle reaches a speed of
above 10 km/ha gain after a full brake appli-
cation.
The hazard warning lamps continue to oper-
ate even if the ignition is switched off. Intelligent Light System
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 illu-
mination of the road surface, 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 foglamps. The system is only active when it is dark.
You can activate or deactivate the "Intelligent
Light System" function using the on-board
computer (Y page 260).
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
you are driving. This allows you to recognise
pedestrians, cyclists and animals.
Active:
when the lights are switched on
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 vis-
ibility in tight bends, for example. It can only
be activated when the dipped-beam head-
lamps are switched on.
Active:
R if you are driving at speeds below 40 km/h
and switch on the turn signal or turn the
steering wheel
R if you are driving at speeds between
40 km/ha nd 70 km/h and turn the steer-
ing wheel
The cornering lamp may remain lit for a short
time, but is automatically switched off after
no more than three minutes.
Motorway mode Exterior lighting

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 mor 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 illumination of the edge of the carriage-
way.
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
driving at speeds above 100 km/h or if you
switch off the rear foglamp Adaptive Highbeam Assist PLUS
General notes With Adaptive Highbeam Assist Plus, you can
automatically switch between dipped-beam,
partial main-beam and main-beam head-
lamps.
Partial main-beam illumination is a form of
illumination whereby the main beam is direc-
ted past other road users. Other road users
are kept out of the main-beam. This prevents glare. If there is a vehicle in front, for example,
the main-beam headlamps illuminate the
areas to its right and left, and the vehicle in
front is illuminated by the dipped-beam head-
lamps.
The system automatically adapts the dipped- beam headlamp range depending on the dis-
tance to the other vehicle. Once the system
no longer detects any other vehicles, it
switches on the main-beam headlamps again.
If the main-beam or partial main-beam head-
lamps are causing too much reflection from
traffic signs, the lights are automatically dim-
med and glare for the driver caused by the
reflections is thus avoided.
The system's optical sensor is located behind
the windscreen near the overhead control
panel. 128

WARNING
Unsuitable footwear can hinder correct usage of the pedals, e.g.:
R shoes with thick soles
R shoes with high heels
R slippers
There is a risk of an accident.
Wear suitable footwear to ensure correct
usage of the pedals. G
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.
! Warm up the engine quickly. Do not use
the engine's full performance until it has
reached operating temperature.
Only set the automatic transmission to the
respective drive positions when the vehicle
is stationary.
Where possible, avoid spinning the drive
wheels when pulling away on slippery
roads. Otherwise, you could damage the
drive train.
! AMG vehicles:
at low engine oil temper-
atures (below +20 †), the maximum
engine speed is restricted in order to pro-
tect the engine. To protect the engine and
maintain smooth engine operation, avoid driving at full throttle when the engine is
cold. Key positions

For safety reasons, Mercedes-Benz recom-
mends only fitting the following brake discs
and brake pads/linings:
R brake discs that have been approved by
Mercedes-Benz
R brake pads/linings that have been
approved by Mercedes-Benz or that are of
an equivalent standard of quality
Other brake discs or brake pads/linings can
compromise the safety of your vehicle.
Always replace all brake discs and brake
pads/linings on an axle at the same time.
Always fit new brake pads/linings when
replacing brake discs.
The vehicle is equipped with lightweight
brake discs to which the wheel assembly with
rim and threaded connection is matched.
The use of brake discs other than those
approved by Mercedes-Benz may alter track
width and is subject to approval, if applicable.
Shock-type loads when handling the brake
discs, such as when changing wheels, can
lead to a reduction in comfort when driving
with lightweight brake discs. Avoid shock-
type loads on the lightweight brake discs,
particularly on the brake plate.
AMG high-performance and ceramic
brakes The high-performance brake system is only
available on AMG vehicles.
The AMG brake systems are designed for
heavy loads. This may lead to noise when
braking. This is dependent on:
R speed
R braking force
R environmental conditions, such as temper-
ature and humidity
The wear of individual brake system compo-
nents such as the brake pads/linings or brake discs depends on individual driving style and
operating conditions.
For this reason, it is impossible to state a
mileage (service life) that will be valid under all circumstances. An aggressive driving style
will lead to high wear. You can obtain further information about this from your Mercedes-
Benz Service Centre.
Brake pads/linings and discs that are either
new or have been replaced only achieve opti- mum braking effect after several hundred kil-
ometres of driving. Compensate for the
reduced braking effect by applying greater
force to the brake pedal. Always be aware of
this and adapt your driving and braking
accordingly during the running-in period.
Excessive heavy braking results in corre-
spondingly high brake wear. Observe the
brake wear warning lamp in the instrument
cluster and note any brake status messages
in the multifunction display. If you regularly
drive at high speeds, it is particularly impor-
tant to have the brake system checked and
maintained regularly. Driving on wet roads
Aquaplaning If water has accumulated to a certain depth
on the road surface, there is a danger of aqua-
planing occurring, even if:
R you are driving at low speeds
R the tyres have adequate tread depth
For this reason, drive in the following manner in the event of heavy rain or in conditions in
which aquaplaning can occur:
R lower your speed
R avoid tyre ruts
R avoid sudden steering movements
R brake carefully
Driving on flooded roads !
Bear in mind that vehicles travelling in
front or in the opposite direction create
waves. This may cause the maximum per-
missible water depth to be exceeded.
These notes must be observed under all
circumstances. You could otherwise dam- 184
