The automatic headlamp feature is only an
aid. The driver is responsible for the vehicle's
lighting at all times.
Ãis the favored light switch setting. The
light setting is automatically selected accord-
ing to the brightness of the ambient light
(exception: poor visibility due to weather con-
ditions such as fog, snow or spray):
RSmartKey in position 1in the ignition lock:
the parking lamps are switched on or off
automatically depending on the brightness
of the ambient light.
RWith the engine running: if you have acti-
vated the daytime running lamps function
via the on-board computer, the daytime
running lamps or the parking lamps and the
low-beam headlamps are switched on or off
automatically depending on the brightness
of the ambient light.
XTo switch on automatic headlamp
mode: turn the light switch to Ã.
Only for Canada:
The daytime running lamps improve the visi-
bility of your vehicle during the day. The day-
time running lamps function is required by law
in Canada. It cannot therefore be deactivated.
When the engine is running and the vehicle is
stationary: if you move the selector lever from
a drive position to P, the daytime running
lamps/low-beam headlamps go out after
three minutes.
When the engine is running, the vehicle is
stationary and in bright ambient light: if you
turn the light switch to T, the daytime
running lamps and parking lamps switch on.
If the engine is running and you turn the light switch to L, the manual settings take
precedence over the daytime running lamps.
USA only:
The daytime running lamps improve the visi-
bility of your vehicle during the day. To do this,
the daytime running lamps function must be
switched on using the on-board computer
(
Ypage 205). If the engine is running and you turn the light
switch to
TorL, the manual settings
take precedence over the daytime running
lamps.
Low-beam headlamps
GWARNING
When the light switch is set to Ã, the low-
beam headlamps may not be switched on
automatically if there is fog, snow or other
causes of poor visibility due to the weather
conditions such as spray. There is a risk of an
accident.
In such situations, turn the light switch to
L.
Even if the light sensor does not detect that it
is dark, the parking lamps and low-beam
headlamps switch on when the ignition is
switched on and the light switch is set to the
L position. This is a particularly useful
function in the event of rain and fog.
XTo switch on the low-beam headlamps:
turn the SmartKey in the ignition lock to
position 2or start the engine.
XTurn the light switch to L.
The green Lindicator lamp in the instru-
ment cluster lights up.
Rear fog lamp
The rear fog lamp improves visibility of your
vehicle for the traffic behind in the event of
thick fog. Please take note of the country-
specific regulations for the use of rear fog
lamps.
XTo switch on the rear fog lamps: turn the
SmartKey to position 2in the ignition lock
or start the engine.
XTurn the light switch to LorÃ.
XPress the Rbutton.
The yellow Rindicator lamp in the
instrument cluster lights up.
XTo switch off the rear fog lamp: press the

driving. This allows you to identify pedes-
trians, cyclists and animals.
Active:when the lights are switched on.
Adaptive Highbeam Assist
General notes
You can use this function to set the head-
lamps to change between low beam and high beam automatically. The system recognizes
vehicles with their lights on, either approach-
ing from the opposite direction or traveling in
front of your vehicle, and consequently
switches the headlamps from high beam to
low beam.
The system automatically adapts the low-
beam headlamp range depending on the dis-
tance to the other vehicle. Once the system
no longer detects any other vehicles, it reac-
tivates the high-beam headlamps.
The system's optical sensor is located behind
the windshield near the overhead control
panel.
Important safety notes
GWARNING
Adaptive Highbeam Assist does not recognize
road users:
Rwho have no lights, e.g. pedestrians
Rwho have poor lighting, e.g. cyclists
Rwhose lighting is blocked, e.g. by a barrier
In very rare cases, Adaptive Highbeam Assist
may fail to recognize other road users that
have lights, or may recognize them too late. In this or similar situations, the automatic high-
beam headlamps will not be deactivated or
activated regardless. There is a risk of an acci-
dent.
Always carefully observe the traffic conditions
and switch off the high-beam headlamps in
good time.
Adaptive Highbeam Assist cannot take into
account road, weather or traffic conditions.
Adaptive Highbeam Assist is only an aid. Youare responsible for adjusting the vehicle's
lighting to the prevailing light, visibility and
traffic conditions.
In particular, the detection of obstacles can
be restricted if there is:
Rpoor visibility, e.g. due to fog, heavy rain or
snow
Rdirt on the sensors or the sensors are
obscured

!
Do not operate the windshield wipers
when the windshield is dry, as this could
damage the wiper blades. Moreover, dust
that has collected on the windshield can
scratch the glass if wiping takes place when
the windshield is dry.
If it is necessary to switch on the windshield
wipers in dry weather conditions, always
use washer fluid when operating the wind-
shield wipers.
!If the windshield wipers leave smears on
the windshield after the vehicle has been
washed in an automatic car wash, wax or
other residues may be the reason for this.
Clean the windshield using washer fluid
after washing the vehicle in an automatic
car wash.
!Intermittent wiping with rain sensor: due
to optical influences and the windshield
becoming dirty in dry weather conditions,
the windshield wipers may be activated
inadvertently. This could then damage the
windshield wiper blades or scratch the
windshield.
For this reason, you should always switch
off the windshield wipers in dry weather.

shield wiper to wipe more frequently.
If the wiper blades are worn, the windshield
will no longer be wiped properly. This could
prevent you from observing the traffic condi-
tions.
Replacing the wiper blades
Important safety notes
GWARNING
If the windshield wipers begin to move while
you are changing the wiper blades, you could be trapped by the wiper arm. There is a risk of
injury.
Always switch off the windshield wipers and
ignition before changing the wiper blades.
!To avoid damaging the wiper blades,
make sure that you touch only the wiper
arm of the wiper.
!Never open the hood if a windshield wiper
arm has been folded away from the wind-
shield.
Never fold a windshield wiper arm without a
wiper blade back onto the windshield.
Hold the windshield wiper arm firmly when
you change the wiper blade. If you release
the windshield wiper arm without a wiper
blade and it falls onto the windshield, the windshield may be damaged by the force of
the impact.
Mercedes-Benz recommends that you have
the wiper blades changed at a qualified
specialist workshop.
!Always position the windshield wiper
arms vertically before folding them away
from the windshield. By doing so, you will
avoid damage to the hood.

Notes on breaking-in a new vehicle
Important safety notes
The sensor system of some driving and driv-
ing safety systems adjusts automatically
while a certain distance is being driven after
the vehicle has been delivered or after
repairs. Full system effectiveness is not
reached until the end of this teach-in proce-
dure.
New and replaced brake pads and discs only
reach their optimum braking effect after sev-
eral hundred kilometers of driving. Compen-
sate for this by applying greater force to the
brake pedal.
The first 1000 miles (1500 km)
The more you look after the engine when it is
new, the more satisfied you will be with its
performance in the future.
RYou should therefore drive at varying vehi-
cle and engine speeds for the first
1,000 miles (1,500 km).
RAvoid heavy loads, e.g. driving at full throt-
tle, during this period.
RChange gear in good time, before the tach-
ometer needle is Ôof the way to the red
area of the tachometer.
RDo not manually shift to a lower gear to
brake the vehicle.
RTry to avoid depressing the accelerator
pedal beyond the point of resistance (kick-
down).
RIdeally, for the first 1,000 miles (1,500 km),
drive in program C.
After 1,000 miles (1,500 km), you can
increase the engine speed gradually and bring
the vehicle to full speed.
Additional breaking-in notes for Mercedes-
AMG vehicles:
RDo not drive faster than 85 mph
(140 km/h) for the first 1,000 miles
(1,500 km).
ROnly allow the engine to reach a maximum
engine speed of 4,500 rpm briefly.
RChange gear in good time.
You should also observe these notes on
breaking in if the engine or parts of the drive
train on your vehicle have been replaced.
Always observe the maximum permissible
speed.
Self-locking rear axle differential
(Mercedes-AMG vehicles)
Your vehicle is equipped with a self-locking
differential on the rear axle.
Change the oil to improve protection of the
rear axle differential:
Rafter a breaking-in period of 1,850 miles
(3,000 km)
Revery 31,000 miles (50,000 km) or
3 years
These oil changes prolong the service life of
the differential. Have the oil change carried
out at a qualified specialist workshop.

iCruise control is not deactivated if you
depress the accelerator pedal. For exam-
ple, if you accelerate briefly to overtake,
cruise control adjusts the vehicle's speed
to the last speed stored after you have fin- ished overtaking.
Deactivating cruise control

There are several ways to deactivate cruise
control:
XBriefly press the cruise control lever for-
wards :.
or
XBrake.
Cruise control is automatically deactivated if:
Ryou engage the electric parking brake
Ryou are driving at less than 20 mph
(30 km/h)
RESP®intervenes or you deactivate ESP®
Ron vehicles with manual transmission, you
shift to a gear that is too high, and as a
result the engine speed is too low
Ryou shift the transmission to position N

If cruise control is deactivated, you will hear a
warning tone. You will see the Cruise Con‐
trol Offmessage in the multifunction dis-
play for approximately five seconds.
iWhen you switch off the engine, the last
speed stored is cleared.
DISTRONIC PLUS
General notes
DISTRONIC PLUS regulates the speed and
automatically helps you maintain the dis-
tance to the vehicle detected in front. Vehi-
cles are detected with the aid of the radar
sensor system. DISTRONIC PLUS brakes
automatically to avoid exceeding the set
speed or to maintain the designated distance
from the vehicle in front.
Change into a lower gear in good time on long
and steep downhill gradients. This is espe-
cially important if the vehicle is laden. By
doing so, you will make use of the braking
effect of the engine. This relieves the load on
the brake system and prevents the brakes
from overheating and wearing too quickly.
If DISTRONIC PLUS detects that there is a risk
of a collision, you will be warned visually and
acoustically. DISTRONIC PLUS cannot pre-
vent a collision without your intervention. An
intermittent warning tone will then sound and the distance warning lamp will light up in the
instrument cluster. Brake immediately in
order to increase the distance to the vehicle
in front or take evasive action provided it is
safe to do so.
DISTRONIC PLUS operates in range between
0 mph (0 km/h) and 120 mph (200 km/ h).
Do not use DISTRONIC PLUS while driving on
roads with steep gradients.

If this braking force is insufficient, DISTRONIC
PLUS warns you visually and audibly. There is a risk of an accident.
In such cases, apply the brakes yourself and
try to take evasive action.
!If DISTRONIC PLUS or the HOLD function
is activated, the vehicle brakes automati-
cally in certain situations. To prevent damage to the vehicle, deacti-
vate DISTRONIC PLUS and the HOLD func-
tion in the following or other similar situa-
tions:
Rwhen towing the vehicle
Rin the car wash
If you fail to adapt your driving style,
DISTRONIC PLUS can neither reduce the risk
of accident nor override the laws of physics.
DISTRONIC PLUS cannot take into account
the road, traffic and weather conditions.
DISTRONIC PLUS is only an aid. You are
responsible for the distance to the vehicle in
front, for vehicle speed, for braking in good
time and for staying in your lane.
Do not use DISTRONIC PLUS:
Rin road and traffic conditions which do not
allow you to maintain a constant speed e.g.
in heavy traffic or on winding roads
Ron slippery road surfaces. Braking or accel-
erating could cause the drive wheels to lose
traction and the vehicle could then skid
Rwhen there is poor visibility, e.g. due to fog,
heavy rain or snow
DISTRONIC PLUS may not detect narrow
vehicles driving in front, e.g. motorcycles, or
vehicles driving on a different line.
In particular, the detection of obstacles can
be impaired if:
Rthere is dirt on the sensors or anything else
covering the sensors
Rthere is snow or heavy rain
Rthere is interference by other radar sources
Rthere are strong radar reflections, for
example, in parking garages
If DISTRONIC PLUS no longer detects a vehi- cle in front, DISTRONIC PLUS may unexpect-
edly accelerate the vehicle to the stored
speed.

PARKTRONIC
Important safety notes
PARKTRONIC is an electronic parking aid with
ultrasonic sensors. It indicates visually and
audibly the distance between your vehicle
and an object.
PARKTRONIC is only an aid. It is not a replace-
ment for your attention to your immediate
surroundings. You are always responsible for
safe maneuvering, parking and exiting a park-
ing space. When maneuvering, parking or
pulling out of a parking space, make sure that
there are no persons, animals or objects in
the area in which you are maneuvering.
!When parking, pay particular attention to
objects above or below the sensors, such
as flower pots or trailer drawbars.
PARKTRONIC does not detect such objects
when they are in the immediate vicinity of
the vehicle. You could damage the vehicle
or the objects.
The sensors may not detect snow and other
objects that absorb ultrasonic waves.
Ultrasonic sources such as an automatic
car wash, the compressed-air brakes on a
truck or a pneumatic drill could cause
PARKTRONIC to malfunction.
PARKTRONIC may not function correctly on
uneven terrain.
PARKTRONIC is activated automatically when
you:
Rswitch on the ignition
Rmove the selector lever to position D,R or
N on vehicles with automatic transmission
Rrelease the electric parking brake.
PARKTRONIC is deactivated at speeds above
11 mph (18 km/h). It is reactivated at lower
speeds. PARKTRONIC monitors the area around your
vehicle using six sensors in the front bumper
and four sensors in the rear bumper.
Range of the sensors
General notes
PARKTRONIC does not take objects into con-
sideration that are:
Rbelow the detection range, e.g. people, ani-
mals or objects.
Rabove the detection range, e.g. overhang-
ing loads, truck overhangs or loading
ramps.
