All turn signals flash. If you now switch on a
turn signal using the combination switch, only the turn signal lamp on the corresponding
side of the vehicle will flash.
X To switch off the hazard warning lamps:
press button
0043.
The hazard warning lamps automatically switch
on if:
R an air bag is deployed or
R the vehicle decelerates rapidly from a speed
of above 45 mph (70 km/h) and comes to a
standstill
The hazard warning lamps switch off automati-
cally if the vehicle reaches a speed of above
6 mph (10 km/h) again after a full brake appli-
cation.
i The hazard warning lamps still operate 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 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, highway 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 239).
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 driving. This
allows you to recognize pedestrians, cyclists
and animals sooner.
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 the
direction you are turning, enabling better visi-
bility in tight bends, for example. It can only be
activated when the low-beam headlamps are
switched on.
Active:
R if you are driving at speeds below 25 mph
(40 km/h) and switch on the turn signal or
turn the steering wheel
R if you are driving at speeds between 25 mph
(40 km/h) and 45 mph (70 km/h) and turn
the steering wheel
The cornering lamp may remain lit for a short
time, but is automatically switched off after no
more than three minutes.
Cornering light function with traffic circle
function: 112
Exterior lightingLights and windshield wipers
Page 115 of 398

The cornering light function is activated on both
sides before entering a traffic circle through an
evaluation of the current GPS position of the
vehicle. It remains active until after the vehicle
has left the traffic circle. In this way, pedestrians
crossing the road, for example, are illuminated
by your vehicle in good time.
Highway mode Highway 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 fog lamps The extended range fog lamps reduce the glare
experienced by the driver and improve the illu-
mination of the edge of the road.
Active: if you are driving at speeds below
40 mph (70 km/ h)and you switch on the rear
fog lamp.
Not active: if, following activation, you are driv-
ing at speeds above 60 mph (100 km/h)or if you
switch off the rear fog lamp
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 low-beam headlamps.
Active: when driving at speeds no faster than
30 mph (50 km/h) and the off-road program
selector wheel is in position 1 or 2.
Not active: when driving at speeds above
30 mph (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. Adaptive Highbeam Assist
General notes You can use this function to set the headlamps
to change between low beam and high beam
automatically. The system recognizes vehicles
with their lights on, either approaching from the
opposite direction or traveling in front of your
vehicle, and consequently switches the head-
lamps from high beam to low beam.
The system automatically adapts the low-beam
headlamp range depending on the distance to
the other vehicle. Once the system no longer
detects any other vehicles, it reactivates the
high-beam headlamps.
The system's optical sensor is located behind
the windshield near the overhead control panel.
Important safety notes G
WARNING
Adaptive Highbeam Assist does not recognize road users:
R who have no lights, e.g. pedestrians
R who have poor lighting, e.g. cyclists
R whose lighting is blocked, e.g. by a barrier
On very rare occasions, Adaptive Highbeam
Assist may fail to recognize other road users
that have lights, or may recognize them too
late. In this, or in similar situations, the auto-
matic high-beam headlamps will not be deac-
tivated or will be activated regardless. There is a risk of an accident.
Always carefully observe the traffic conditionsand 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. You are responsible for adjusting the vehicle's lighting
to the prevailing light, visibility and traffic con-
ditions.
In particular, the detection of obstacles can be
impaired if:
R poor visibility, e.g. due to fog, heavy rain or
snow
R dirt on the sensors or the sensors are
obscured Exterior lighting

Overview of climate control systems
General notes
Observe the settings recommended on the fol-
lowing pages. The windows could otherwise fog up.
To prevent the windows from fogging up:
R Switch off climate control only briefly
R Switch on air-recirculation mode only briefly
R Switch on the cooling with air dehumidifica-
tion function
R Activate the "Windshield defrosting" function
briefly, if required
Climate control regulates the temperature and
the humidity in the vehicle interior and filters
undesirable substances out of the air.
The "Cooling with air dehumidification" function
is only available when the engine is running.
Optimum climate control is only achieved with
the side windows and roof closed.
The residual heat function can only be activated or deactivated with the ignition switched off
(Y page 131).
i Ventilate the vehicle for a brief period during
warm weather, e.g. using the convenience
opening feature (Y page 89). This will speed
up the cooling process and the desired inte-
rior temperature will be reached more
quickly. If you start the engine using your smartphone,
the last selected climate control setting is reac-
tivated (Y page 137).
i The integrated filter filters out most parti-
cles of dust and soot and completely filters
out pollen. It also reduces gaseous pollutants and odors. A clogged filter reduces the
amount of air supplied to the vehicle interior.
Depending on the operating conditions and
environmental influences, the interval for
replacing the filter may be shorter than speci- fied.
i Vehicles with ionization of the interior
air with air filter: in addition to ionization,
the vehicle has an air filter with anti-allergenic properties that contribute to improved air fil-
tration.
i It is possible that under certain circumstan-
ces the residual heat function may be activa-
ted automatically an hour after the SmartKey has been removed in order to dry the auto-
matic climate control. The vehicle is then ven-tilated for 30 minutes.
i Plug-in hybrid vehicles:
observe the notes
on climate control in the separate operating
instructions. 122

This helps you to avoid overheating the
brakes and wearing them out excessively.
When you take advantage of engine braking, a
drive wheel may not turn for some time, e.g.
on a slippery road surface. This could cause
damage to the drive train. This type of damage is not covered by the Mercedes-Benz war-
ranty.
Do not depress the brake pedal continuously
while the vehicle is in motion, e.g. causing the
brakes to rub by constantly applying light pres-
sure to the pedal. This results in excessive and
premature wear to the brake pads.
Use the left-hand steering wheel paddle shifter
to shift into a lower gear in good time on long
and steep downhill gradients. This is especially
important if the vehicle is laden.
This also applies if you have activated cruise
control, the limiter or Active Distance Assist
DISTRONIC.
This will use the braking effect of the engine, so
that less braking will be required to maintain the
speed. This relieves the load on the brake sys-
tem and prevents the brakes from overheating
and wearing too quickly.
Heavy and light loads G
WARNING
If you rest your foot on the brake pedal while
driving, the braking system can overheat. This increases the stopping distance and can even
cause the braking system to fail. There is a
risk of an accident.
Never use the brake pedal as a footrest. Never
depress the brake pedal and the accelerator
pedal at the same time.
! Depressing the brake pedal constantly
results in excessive and premature wear to
the brake pads.
If the brakes have been subjected to a heavy
load, do not stop the vehicle immediately. Drive on for a short while. This allows the airflow to
cool the brakes more quickly.
Wet roads If you have driven for a long time in heavy rain
without braking, there may be a delayed reac-
tion from the brakes when braking for the first time. This may also occur after the vehicle has
been washed or driven through deep water.
You then have to depress the brake pedal more
firmly. Maintain a greater distance from the
vehicle in front.
After driving on a wet road or having the vehicle
washed, brake firmly while paying attention to
the traffic conditions. This will warm up the
brake discs, thereby drying them more quickly
and protecting them against corrosion.
Limited braking performance on salt-
treated roads If you drive on salted roads, a layer of salt resi-
due may form on the brake discs and brake
pads. This can result in a significantly longer
braking distance.
R Brake occasionally to remove any possible
salt residue. Make sure that you do not
endanger other road users when doing so.
R Carefully depress the brake pedal and the
beginning and end of a journey.
R Maintain a greater distance to the vehicle
ahead.
Servicing the brakes !
The brake fluid level may be too low, if:
R if the red brake warning lamp lights up in
the instrument cluster and
R you hear a warning tone while the engine is
running
Observe additional warning messages in the
multifunction display.
The brake fluid level may be too low due to
brake pad wear or leaking brake lines.
Have the brake system checked immediately.
Consult a qualified specialist workshop to
arrange this.
! A function or performance test should only
be carried out on a 2-axle dynamometer. If
you wish to operate the vehicle on such a
dynamometer, please consult a qualified spe- cialist workshop in advance. You could oth-
erwise damage the drive train or the brake
system.
! Because ESP ®
is an automatic system, the
engine and ignition must be switched off
(SmartKey in position 0or 1or Start/Stop
button in position 0or 1) when the electric 162
Driving tipsDriving and parking
Page 165 of 398

parking brake is being tested on a brake dyna-
mometer (maximum 10 seconds).
Braking triggered automatically by ESP ®
may
seriously damage the brake system.
All checks and maintenance work on the brake
system must be carried out at a qualified spe-
cialist workshop.
Have brake pads installed and brake fluid
replaced at a qualified specialist workshop.
If the brake system has only been subject to
moderate loads, you should test the functional-
ity of your brakes at regular intervals. To do so,
depress the brake pedal firmly when driving at a high speed. This improves the grip of the brake
pads.
You can find a description of Brake Assist (BAS)
on (Y page 67) or of BAS PLUS on (Y page 72).
Mercedes-Benz recommends that you only have
brake pads/linings installed on your vehicle
which have been approved for Mercedes-Benz
vehicles or which correspond to an equivalent
quality standard. Brake pads/linings which have not been approved for Mercedes-Benz vehicles
or which are not of an equivalent quality could
affect your vehicle's operating safety.
Mercedes-Benz recommends that you only use
brake fluid that has been specially approved for your vehicle by Mercedes-Benz, or which corre-
sponds to an equivalent quality standard. Brake fluid which has not been approved for
Mercedes-Benz vehicles or which is not of an
equivalent quality could affect your vehicle's
operating safety.
High-performance brake system
(Mercedes-AMG vehicles) The high-performance brake system is designed
for heavy loads. This may lead to noise when
braking. This will depend on:
R Speed
R Braking force
R Environmental conditions, such as tempera-
ture and humidity
The wear of individual components of the brake system, such as the brake pads/linings or brake discs, depends on the individual driving style
and operating conditions.
For this reason, it is impossible to state a mile-
age 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 authorized Mercedes-Benz Center.
New and replaced brake pads and discs only
reach their optimum braking effect after several
hundred kilometers of driving. Compensate for
this by applying greater force to the brake pedal. Keep this in mind, and adapt your driving and
braking accordingly during this break-in period.
Excessive heavy braking results in correspond-
ingly high brake wear. Observe the 0026brake
wear warning lamp in the instrument cluster and
note any brake status messages in the multi-
function display. Especially for high perform-
ance driving, it is important to maintain and have
the brake system checked regularly. Driving on wet roads
Hydroplaning If water has accumulated to a certain depth on
the road surface, there is a danger of hydro-
planing occurring, even if:
R you drive at low speeds
R the tires have adequate tread depth
For this reason, in the event of heavy rain or in
conditions in which hydroplaning may occur,
you must drive in the following manner:
R lower your speed
R avoid ruts
R avoid sudden steering movements
R brake carefully
Driving on flooded roads !
Do not drive through flooded areas. Check
the depth of any water before driving through
it. Drive slowly through standing water. Oth-
erwise, water could enter the vehicle interior
or engine compartment. It can then damage
the engine's or automatic transmission's
electronic components. It can also be sucked
in by the engine's air intake connection and
cause engine damage.
i Vehicles with the AIRMATIC Package:
select the raised vehicle level before driving
through a body of water. Driving tips
163Driving and parking Z
Page 166 of 398

Off-road fording
!
Under no circumstances should you accel-
erate before entering the water. The bow
wave could cause water to enter and damage
the engine and other assemblies.
! Do not open any of the vehicle's doors while
fording. Otherwise, water could get into the
vehicle interior and damage the vehicle's
electronics and interior equipment.
R Establish how deep the water is and the char-
acteristics of the body of water before ford-
ing.
R Select the highest possible vehicle level.
R Shift to a lower gear using the left-hand steer-
ing wheel paddle shifter.
R Avoid high engine speeds.
R Enter and exit the water at a flat place and at
a steady walking pace.
R Drive slowly and at an even speed through the
water.
R Ensure that a bow wave does not form as you
drive.
R Do not stop and do not switch off the engine.
Water offers a high degree of resistance, and the ground is slippery and in some cases
unstable. Therefore, it is difficult and danger-
ous to pull away in the water.
R Clean any mud from the tire tread after ford-
ing.
R Apply the brakes to dry them after fording.
Always observe the fording depth values
(Y page 392). Winter driving
G
WARNING
If you shift down on a slippery road surface in an attempt to increase the engine's braking
effect, the drive wheels could lose their grip.
There is an increased danger of skidding and
accidents.
Do not shift down for additional engine brak-
ing on a slippery road surface. G
DANGER
If the exhaust pipe is blocked or adequate
ventilation is not possible, poisonous gases such as carbon monoxide (CO) may enter the
vehicle. This is the case, e.g. if the vehicle
becomes trapped in snow. There is a risk of
fatal injury.
If you leave the engine or the auxiliary heating
running, make sure the exhaust pipe and area
around the vehicle are clear of snow. To
ensure an adequate supply of fresh air, open a window on the side of the vehicle that is not
facing into the wind.
! When scraping ice off the rear window, take
care not to damage the rear-window seal or
trim.
Have your vehicle winter-proofed at a qualified
specialist workshop at the onset of winter.
Drive particularly carefully on slippery road sur- faces. Avoid sudden acceleration, steering and
braking maneuvers. Do not use cruise control or
Active Distance Assist DISTRONIC.
If the vehicle threatens to skid or cannot be
stopped when moving at low speed:
X Shift the transmission to position 005C.
X Try to bring the vehicle under control using
corrective steering.
When driving in snow with or without snow
chains, select driving program Slippery
(Y page 142).
i Vehicles with a diesel engine:
do not
cover the radiator, e.g. with a protective
cover. The measuring function of the on-
board diagnosis system may otherwise pro-
vide inaccurate values. Some of these values
are required by law and must therefore always be accurate.
The outside temperature indicator is not
designed to serve as an ice-warning device and
is therefore unsuitable for that purpose.
Changes in the outside temperature are dis-
played after a short delay.
Indicated temperatures just above the freezing
point do not guarantee that the road surface is
free of ice. The road may still be icy, especially in wooded areas or on bridges. You should pay
special attention to road conditions when tem-
peratures are around the freezing point.

Important safety notes
G
WARNING
Active Distance Assist DISTRONIC does not
react to:
R people or animals
R stationary objects in the road, e.g. stopped
or parked vehicles
R oncoming vehicles and crossing traffic
As a result, Active Distance Assist DISTRONIC
may neither give warnings nor intervene in
such situations. There is a risk of an accident.
Always pay careful attention to the traffic sit- uation and be ready to brake. G
WARNING
Active Distance Assist DISTRONIC cannot
always clearly identify other road users and
complex traffic situations.
In such cases, Active Distance Assist
DISTRONIC can:
R give an unnecessary warning and then
brake the vehicle
R neither give a warning nor intervene
R accelerate or brake unexpectedly
There is a risk of an accident.
Continue to drive carefully and be ready to
brake, especially if Active Distance Assist
DISTRONIC warns you. G
WARNING
Active Distance Assist DISTRONIC brakes
your vehicle with up to 50% of the maximum
possible deceleration. If this deceleration is
not sufficient, Active Distance Assist
DISTRONIC alerts you with a visual and acous- tic warning. There is a risk of an accident.
Adjust your speed in these cases and main-
tain sufficient distance.
Apply the brakes yourself and/or take evasive
action.
! When Active Distance Assist DISTRONIC or
the HOLD function is activated, the vehicle
brakes automatically in certain situations. To avoid damage to the vehicle, deactivate
Active Distance Assist DISTRONIC and the
HOLD function in the following or similar sit-
uations:
R when towing the vehicle
R in the car wash
Active Distance Assist DISTRONIC:
R Can neither reduce the risk of accident nor
override the laws of physics if you fail to adapt
your driving style.
R Cannot take into account road, weather or
traffic conditions.
R Is only an aid.
You are responsible for the distance to the vehi-
cle in front, for vehicle speed, for braking in good
time and for staying in your lane.
Do not use Active Distance Assist DISTRONIC:
R In road and traffic conditions which do not
allow you to maintain a constant speed, e.g. in
heavy traffic or on winding roads
R On icy or slippery roads; braking or acceler-
ating can cause the drive wheels to lose trac-
tion and the vehicle could then skid
R In poor visibility, e.g. due to fog, heavy rain or
snow
Active Distance Assist DISTRONIC may not
detect narrow vehicles driving in front, e.g.
motorcycles, or vehicles driving in a staggered
formation.
In particular, the detection of obstacles can be
impaired if:
R There is dirt on the sensors or anything else
covering the sensors
R There is snow or heavy rain
R There is interference by other radar sources
R There are strong radar reflections, for exam-
ple in parking garages
If Active Distance Assist DISTRONIC no longer
detects a vehicle in front, Distance Pilot
DISTRONIC may unexpectedly accelerate to the
speed stored.
This speed may:
R Be too high if you are driving in a turning lane
or an exit lane
R Be so high when driving in the right-hand lane
that you overtake vehicles in the left-hand
lane
R Be so high in the left lane that you pass vehi-
cles driving on the right 172

Important safety notes
Active Distance Assist DISTRONIC with Active
Steering Assist can neither reduce the risk of an accident if you fail to adapt your driving style,
nor override the laws of physics. It cannot take
into account road, weather or traffic conditions.Active Distance Assist DISTRONIC with Active
Steering Assist is only an aid. You are responsi-
ble for the distance to the vehicle in front, for
vehicle speed, for braking in good time and for
staying in your lane.
Active Distance Assist DISTRONIC with Active
Steering Assist does not detect road and traffic conditions and does not detect all road users. If
you are following a vehicle which is driving
towards the edge of the road, your vehicle could
come into contact with the curb or other road
boundaries. Be particularly aware of other road
users, e.g. cyclists, that are directly next to your vehicle.
Obstacles such as traffic pylons on the lane or
projecting out into the lane are not detected.
An inappropriate steering intervention, e.g. after
intentionally driving over a lane marking, can be
corrected at any time if you steer slightly in the opposite direction.
Active Distance Assist DISTRONIC with Active
Steering Assist cannot continuously keep your
vehicle in lane. In some cases, the steering
intervention is not sufficient to bring the vehicleback to the lane. In such cases, you must steer
the vehicle yourself to ensure that it does not
leave the lane.
The support provided by the system can be
impaired if:
R there is poor visibility, e.g. due to insufficient
illumination of the road, or due to snow, rain,fog or heavy spray
R there is glare, e.g. from oncoming traffic, the
sun or reflection from other vehicles (e.g. if
the road surface is wet)
R the windshield is dirty, fogged up, damaged or
covered, for instance by a sticker, in the vicin-ity of the camera
R there are no or several unclear lane markings
for one lane, e.g. roadworks
R the lane markings are worn away, dark or cov-
ered up, e.g. by dirt or snow R
the distance to the vehicle in front is too short
and thus the lane markings cannot be detec-
ted
R the lane markings change quickly, e.g. lanes
branch off, cross one another or merge
R the road is narrow and winding
R there are highly variable shade conditions on
the roadway
The system is switched to passive and no longer assists you by performing steering interventions
if:
R you actively change lane
R you switch on the turn signal
R you take your hands off the steering wheel or
do not steer for a prolonged period of time
i Once you have finished changing lanes,
Active Steering Assist automatically reacti-
vates.
Active Steering Assist cannot provide assis-
tance: R on very sharp corners
R when towing a trailer
R when a loss of tire pressure or a defective tire
has been detected and displayed
Observe the important safety notes on Active
Distance Assist DISTRONIC (Y page 172).
The steering interventions are carried out with a limited steering moment. The system requires
the driver to keep his hands on the steering
wheel and to steer himself.
If you do not steer yourself or if you take your
hands off the steering wheel for a prolonged
period of time, the system will first alert you with
a visual warning. A steering wheel symbol
appears in the multifunction display. If you have still not started to steer and have not taken hold
of the steering wheel after five seconds at the
latest, a warning tone also sounds to remind you
to take control of the vehicle. Active Steering
Assist is then switched to passive. Active Dis-
tance Assist DISTRONIC remains active.

Road Engineering package)
Important safety notes Level control adapts the vehicle level automati-
cally to the current operating and driving situa-
tion. This results in reduced fuel consumption
and improved handling.
Make changes to the vehicle level while the
vehicle is in motion. This enables the vehicle to adjust to the new level as quickly as possible.
The vehicle level may change visibly if you park
the vehicle and the outside temperature
changes. If the temperature drops, the vehicle
level is lower; with an increase in temperature,
the vehicle level rises.
If you unlock the vehicle or open a door, the
vehicle begins to compensate for load discrep-
ancies while still parked. However, for signifi-
cant level changes, such as after the vehicle has
been stationary for a long period, the engine
must be on. For safety reasons, the vehicle is
only lowered when the doors are closed. Low- ering is interrupted if a door is opened, and it
continues once the door has been closed.

WARNING
When the vehicle is being lowered, people
could become trapped if their limbs are
between the vehicle body and the wheels or
underneath the vehicle. There is a risk of
injury.
Make sure no one is underneath the vehicle or in the immediate vicinity of the wheel arches

WARNING
When you drive with the vehicle raised, the
driving characteristics could be impaired by
the vehicle's raised center of gravity. The vehi- cle could rollover more easily, for example on
a bend. There is a risk of an accident.
Always select as low a vehicle level as possi-
ble and adjust your driving style. G
WARNING
When you drive with the chassis lowered or
raised, the vehicle's braking and driving char-
acteristics can be significantly impaired. You
could also exceed the permissible vehicle
height if the chassis is raised. There is a risk of an accident.
Adjust the vehicle level before pulling away. G
WARNING
Due to the high center of gravity, the vehicle
may start to skid and roll over in the event of
an abrupt steering maneuver and/or when
the vehicle's speed is not adapted to the road conditions. There is a risk of an accident.
Always adapt your speed and driving style to
the vehicle's driving characteristics and to the prevailing road and weather conditions.
! When driving on extremely rough terrain,
select a high vehicle level in good time. Make
sure there is always sufficient ground clear-
ance. You will otherwise damage the vehicle. Driving systems
