cally if an air bag is deployed.
The hazard warning lamps still operate if the
ignition is switched off.
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:
Rif you are driving at speeds below 25 mph
(40 km/h) and switch on the turn signal or
turn the steering wheel
Rif 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:
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.
Only vehicles with the COMAND multimedia sys-
tem have this function.
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.
114Exterior lighting
Lights and windshield wipers

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
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
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 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. 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:
Rthere is poor visibility, e.g. due to fog, heavy
rain or snow
Rthere is dirt on the sensors or anything else
covering the sensors

display message is
shown instead of range ?in the multifunction
display. The 8warning lamp in the instru-
ment cluster also lights up (
Ypage 274). The ECO display consists of three sections, with
an inner and outer area. The sections corre-
spond to the following three categories:
:Acceleration (evaluation of all accel-
eration processes):
Rthe outer area fills up and the inner area lights up green: moderate
acceleration, especially at higher
speeds
Rthe outer area empties and the
inner area is gray: sporty acceler-
ation
;Coasting (evaluation of all decelera-
tion processes):
Rthe outer area fills up and the inner area lights up green: anticipatory
driving, keeping your distance and
early release of the accelerator.
The vehicle can coast without use
of the brakes.
Rthe outer area empties and the
inner area is gray: frequent heavy
braking
=Constant (continuous evaluation
over the entire journey):
Rthe outer area fills up and the inner area lights up green: constant
speed and avoidance of unneces-
sary acceleration and deceleration
Rthe outer area empties and the
inner area is gray: fluctuations in
speed
The three inner areas display the current driving
style and light up green as a result of a particu-
larly economical driving style. Depending on thedriving situation, up to two areas may light up
simultaneously.
At the beginning of the journey, the three outer
areas are empty and fill up as a result of eco-
nomical driving. A higher level indicates a more
economical driving style. If the three outer areas
are completely filled at the same time, the driver
has adopted the most economical driving style
for the selected settings and prevailing condi-
tions. The ECO display border lights up.
The ECO display does not indicate the actual fuel consumption. The additionally achieved range
displayed under Bonus fr. Start
does not
indicate a fixed consumption reduction.

Driving an d parking

RIn order to prevent any salt build-up, apply the
brakes occasionally while paying attention to
the traffic conditions.
RCarefully depress the brake pedal and the
beginning and end of a journey.
RMaintain a greater distance to the vehicle
ahead.
Servicing the brakes
!The brake fluid level may be too low, if:
Rif the red brake warning lamp lights up in
the instrument cluster and
Ryou 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.
!Vehicles with 4MATIC: function or per-
formance tests may only be carried out on a 2-
axle dynamometer. If you wish to operate the
vehicle on such a dynamometer, please con-
sult a qualified specialist workshop in
advance. You could otherwise damage the
drive train or the brake system.
!Vehicles with 4MATIC: the ESP®system
operates automatically. If the electric parking
brake is tested on a brake dynamometer, the
engine and ignition must be switched off: turn
the SmartKey in the ignition lock to position
u or1 or press the Start/Stop button
repeatedly in accordance with the given
SmartKey positions.
Braking triggered automatically by ESP
®may
cause severe damage to 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.
Information on BAS (Brake Assist System)
(
Ypage 67) and Active Brake Assist with cross-
traffic function (Ypage 73). For safety reasons, Mercedes-Benz recom-
mends only installing the following brake disks
and brake pads/linings:
Rbrake disks that have been approved by
Mercedes-Benz
Rbrake pads/linings that have been approved
by Mercedes-Benz or that are of an equivalent
standard of quality
Other brake disks or brake pads/linings can
compromise the safety of your vehicle.
Always replace all brake disks and brake pads/ linings on a
n axle at the same time. Always
install new brake pads/linings when replacing
brake disks.
The vehicle is equipped with lightweight brake
disks to which the wheel assembly with rim and
threaded connection is matched.
The use of brake disks other than those
approved by Mercedes-Benz can change the
track width and is subject to approval, if appli-
cable.
Shock-type loads when handling the brake
discs, such as when changing wheels, can lead
to a reduction in comfort when driving with light-
weight brake discs. Avoid shock-type loads on
the lightweight brake disks, particularly on the
brake plate.
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.
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:
Ryou drive at low speeds
Rthe 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:
Rlower your speed
Ravoid ruts

Steering Pilot cannot provide assistance:
Ron very sharp corners
Rwhen towing a trailer
Rwhen a loss of tire pressure or a defective tire
has been detected and displayed
Pay attention also to the important safety notes on Distance Pilot DISTRONIC (
Ypage 171).
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, a warning tone also
sounds to remind you to take control of the
vehicle after five seconds at the latest. Steering
Pilot is then switched to passive. Distance Pilot
DISTRONIC remains active.
Activating Steering Pilot

HOLD function
General notes
The HOLD function can assist the driver in the
following situations:
Rwhen pulling away, especially on steep slopes
Rwhen maneuvering on steep slopes
Rwhen waiting in traffic
The vehicle is kept stationary without the driver having to depress the brake pedal.
The braking effect is canceled and the HOLD
function deactivated when you depress the
accelerator pedal to pull away.

The electric parking brake secures the vehicle
automatically if the HOLD function is activated
when the vehicle is stationary and:
Ra system malfunction occurs
Rthe power supply is insufficient
If a malfunction occurs, the transmission may
also be shifted to position jautomatically.
DSR
General notes
DSR (Downhill Speed Regulation) is an aid to
assist you when driving downhill that is available only in vehicles with the Off-Road Engineering
package.
It keeps the speed of travel at the speed selec-
ted on the on-board computer. The steeper the
downhill gradient, the greater the DSR braking
effect on the vehicle. When driving on flat
stretches of road or on an uphill gradient, the
DSR braking effect is minimal or nonexistent.
DSR controls the vehicle’s speed when it is acti-
vated and the transmission is in position h,k
or i. You can drive at a higher or a lower speed
than that set on the on-board computer at any
time by accelerating or braking.
Important safety notes
GWARNING
If the speed driven and the set speed deviate and you activate DSR on a slippery road sur-
face, the wheels may lose traction. There is an
increased danger of skidding and accidents.
Before switching DSR on, please take into
consideration the road surface and the differ- ence between driving speed and the set
speed.
DSR can neither reduce the risk of accident if
you fail to adapt your driving style nor override
the laws of physics. DSR cannot take account of
road, weather and traffic conditions. DSR is only
an aid. You are responsible for maintaining a
safe distance to the vehicle in front, for vehicle
speed, for braking in good time and for staying in
lane.
You are always responsible for keeping control
of the vehicle and for assessing whether the
downhill gradient can be managed. DSR may not always be able to keep to the set speed, depend-
ing on road surface and tire conditions. Select a
set speed suitable for the prevailing conditions
and when necessary, apply the brakes manually.
Further information about "Driving off-road"
(
Ypage 165).
Activating/deactivating DSR
If you activate DSR and no speed has been set,
the vehicle decelerates to 4 mph (6 km/h).
You can activate DSR only when driving at
speeds below 25 mph (40 km/h).
