Driving safety systems
Overview of driving safety systems
In this section, you will find information about
the following driving safety systems:
R ABS (Anti-lock BrakingSystem)
(Y page 66)
R BAS (Brake AssistSystem) (Y page 67)
R Active Brake Assist (Y page 67)
R ESP ®
(E lectronic StabilityProgram)
(Y page 70)
R EBD (Electronic Brake forceDistribution)
(Y page 72)
R ADAPTIVE BRAKE (Y page 72)
R Active Brake Assist with cross-traffic function
(Y page 72)
R Active Steering Assist STEER CONTROL
(Y page 75) Important safety notes
If you fail to adapt your driving style or if you are
inattentive, the driving safety systems can nei-
ther reduce the risk of an accident nor override the laws of physics. Driving safety systems are
merely aids designed to assist driving. You are
responsible for maintaining the distance to the
vehicle in front, for vehicle speed, for braking in
good time, and for staying in lane. Always adapt your driving style to suit the prevailing road and
weather conditions and maintain a safe distance from the vehicle in front. Drive carefully.
The driving safety systems described only work
as effectively as possible when there is ade-
quate contact between the tires and the road
surface. Pay particular attention to the informa- tion regarding tires, recommended minimum
tire tread depths etc. in the "Wheels and tires"
section (Y page 351).
In wintry driving conditions, always use winter
tires (M+S tires )and if necessary, snow chains.
Only in this way will the driving safety systems
described in this section work as effectively as
possible. ABS (Anti-lock Braking System)
General information ABS regulates brake pressure in such a way that
the wheels do not lock when you brake. This
allows you to continue steering the vehicle when braking.
The 0025 ABS warning lamp in the instrument
cluster lights up when the ignition is switched
on. It goes out when the engine is running.
ABS works from a speed of about 5 mph
(8 km/h), regardless of road-surface conditions.
ABS works on slippery surfaces, even when you only brake gently.
Important safety notes i
Observe the "Important safety notes" sec-
tion (Y page 66). G
WARNING
If ABS is faulty, the wheels could lock when
braking. The steerability and braking charac-
teristics may be severely impaired. Addition-
ally, further driving safety systems are deac-
tivated. There is an increased danger of skid- ding and accidents.
Drive on carefully. Have ABS checked imme-
diately at a qualified specialist workshop.
When ABS is malfunctioning, other systems,
including driving safety systems, will also
become inoperative. Observe the information
on the ABS warning lamp (Y page 277) and dis-
play messages which may be shown in the
instrument cluster (Y page 245).
Brakes X
If ABS intervenes: continue to depress the
brake pedal vigorously until the braking sit-
uation is over.
X To make a full brake application: depress
the brake pedal with full force.
If ABS intervenes when braking, you will feel a
pulsing in the brake pedal.
The pulsating brake pedal can be an indication
of hazardous road conditions, and functions as a
reminder to take extra care while driving. 66
Driving safety systemsSafety

Offroad ESP
®
(vehicles with Off-Road
Engineering package) An ESP
®
system specifically suited to off-road
terrain is activated automatically once the off-
road program is activated on:
R Vehicles without the Offroad Engineering
package (Y page 215)
R Vehicles with the Off-Road Engineering pack-
age (Y page 216)
Offroad ESP ®
intervenes with a delay if there is
oversteering or understeering, thus improving
traction.
Crosswind Assist General information
Strong crosswind gusts can impair the ability of your vehicle to drive straight ahead. The cross-
wind driving assistance function integrated in
ESP ®
noticeably reduces these impairments.
ESP ®
intervenes automatically according to the
direction and intensity of the crosswinds affect-
ing your vehicle.
ESP ®
intervenes with stabilizing braking to
assist you in keeping the vehicle in the lane.
Crosswind Assist is active at vehicle speeds
above 50 mph (80 km/h) when driving straight
ahead or cornering gently.
Important safety notes
Crosswind Assist does not work if ESP ®
is
switched off or deactivated because of a mal-
function. EBD (electronic brake force distribu-
tion)
General information EBD monitors and controls the brake pressure
on the rear wheels to improve driving stability
while braking.
Important safety notes i
Observe the "Important safety notes" sec-
tion for driving safety systems (Y page 66). G
WARNING
If EBD is malfunctioning, the rear wheels can
lock, e.g. under full braking. This increases the risk of skidding and an accident.
You should therefore adapt your driving style
to the different handling characteristics. Have the brake system checked at a qualified spe-
cialist workshop.
Observe information regarding indicator and
warning lamps (Y page 277) as well as display
messages (Y page 247). ADAPTIVE BRAKE
ADAPTIVE BRAKE enhances braking safety and
offers increased braking comfort. In addition to
the braking function, ADAPTIVE BRAKE also has the HOLD function (Y page 182) and hill start
assist (Y page 139). Active Brake Assist with cross-traffic
function
General information i
Pay attention to the important safety notes
in the "Driving safety systems" section
(Y page 66).
Active Brake Assist with cross-traffic function
can help you to minimize the risk of a collision
with a vehicle in front or a pedestrian and reduce
the effects of such a collision. If the Active Brake
Assist with cross-traffic function detects a risk
of collision, you will be warned visually and
acoustically and, if necessary, your brake appli- cation will be assisted according to the situa-
tion. If you do not react, the system can also
react by braking automatically. In the event of a detected risk of collision due to crossing traffic,you will also be visually and acoustically warned
as well as assisted by the brake boosting effect
according to the situation.
Active Brake Assist with cross-traffic function is
only available in vehicles with the Driving Assis- tance Plus package.
For Active Brake Assist with cross-traffic func-
tion to assist you when driving, the radar sensor
system and the camera system must be opera-
tional. 72
Driving safety systemsSafety

The blue
0057indicator lamp in the instru-
ment cluster lights up when the high-beam
headlamps are switched on.
X To switch off the high-beam headlamps:
move the combination switch back to its nor- mal position.
The blue 0057indicator lamp in the instru-
ment cluster goes out.
Vehicles with Adaptive Highbeam Assist: if
Adaptive Highbeam Assist is activated, it auto-
matically controls activation and deactivation of
the high-beam headlamps (Y page 113).Hazard warning lamps
X
To switch on the hazard warning lamps:
press button
0043.
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

Hilltops
When driving up an uphill gradient, slightly
reduce pressure on the accelerator immediately
before reaching the brow of the hill. Make use of the vehicle's own impetus to travel over the
brow.
This style of driving prevents:
R the vehicle from lifting off the ground on the
brow of a hill
R the vehicle from traveling too quickly down
the other side
Driving downhill R
Drive slowly.
R Do not drive at an angle down steep inclines.
Steer into the line of fall and drive with the
front wheels aligned straight. Otherwise, the
vehicle could slip sideways, tip and rollover.
R Shift to a lower gear using the left-hand pad-
dle shifter before tackling steep downhill gra-
dients.
R Activate DSR. If this is not sufficient, brake
gently. When doing so, make sure that the
vehicle is facing in the direction of the line of
fall.
R Check that the brakes are working normally
after a long downhill stretch.
i The special off-road ABS setting enables a
precise, brief and repeated locking of the
front wheels. This causes them to dig into
loose earth. Be aware that the front wheels
easily skid across the ground surface if com-
pletely braked and therefore lose their ability
to steer. Driving systems
Intelligent Drive
Mercedes-Benz Intelligent Drive stands for inno-
vative driver assistance and safety systems
which enhance comfort and support the driver in critical situations. With these intelligent co-ordi-
nated systems Mercedes-Benz has set a mile-
stone on the path towards autonomous driving.
Mercedes-Benz Intelligent Drive embraces all
elements of active and passive safety in one well
thought out system – for the safety of the vehi-
cle occupants and that of other road users. Further information on driving safety systems
(Y
page 66). Cruise control
General notes Cruise control maintains a constant road speed
for you. It brakes automatically in order to avoid
exceeding the set speed. You must select a
lower gear in good time on long and steep down-
hill gradients, especially if the vehicle is laden or towing a trailer. 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.
Use cruise control only if road and traffic con-
ditions make it appropriate to maintain a steady speed for a prolonged period. You can store anyroad speed above 20 mph (30 km/h).
i Cruise control should not be activated when
driving off-road.
Important safety notes If you fail to adapt your driving style, cruise con-
trol can neither reduce the risk of an accident
nor override the laws of physics. Cruise control
cannot take into account the road, traffic and
weather conditions. Cruise control 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 cruise control:
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 slippery road surfaces. Braking or accel-
erating could cause the drive wheels to lose
traction and the vehicle could then skid
R when there is poor visibility, e.g. due to fog,
heavy rain or snow
If there is a change of drivers, advise the new
driver of the speed stored. Driving systems

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
