i
Please note that the driving safety sys-
tems described only work as effectively as
possible when there is adequate contact
between the tyres and the road surface.
Pay particular attention to the information
regarding tyres, recommended minimum
tyre tread depths etc. in the "Wheels and
tyres" section (Y page 286).
In wintry driving conditions, always use
winter tyres (M+S tyres) and if necessary,
snow chains. Only in this way will the driv-
ing safety systems described in this section
work as effectively as possible. ABS (Anti-lock Braking System)
Important safety notes i
Observe the "Importan tsafety notes" sec-
tion (Y page 53).
AB Sr egulates brake pressure in such a way
that the wheels do not lock when you brake.
This allows you to continue steering the vehi-
cle when braking.
ABS works from a speed of about 8 km/h
upwards, regardless of road-surface condi-
tions. ABSw orks on slippery surfaces, even
when you only brake gently. G
WARNING
If ABS is faulty, the wheels could lock when
braking. This limits the steerability of the vehi-
cle when braking and the braking distance
may increase.
If ABS is deactivated due to a malfunction,
then BAS and ESP are also deactivated. There
is an increased risk of your vehicle skidding in
certain situations.
You should always adapt your driving style to
suit the prevailing road and weather condi-
tions.
Brakes If ABS intervenes when braking, you will feel
a pulsing in the brake pedal. X
If ABS intervenes: continue to depress the
brake pedal with force until the braking sit-
uation is over.
X To make a full brake application:
depress the brake pedal with full force.
The pulsating brake pedal can be an indica-
tion of hazardous road conditions and func-
tions as a reminder to take extra care while
driving. G
WARNING
Do not depress the brake pedal several times
in quick succession (pumping). Pumping the
brake pedal reduces the braking effect .You
might otherwise not be able to stop the vehi-
cle in time and could cause an accident.
Depress the brake pedal firmly and smoothly. BAS (Brake Assist System)
i Observe the "Important safety notes" sec-
tion (Y page 53).
BAS operates in emergency braking situa-
tions. If you depress the brake pedal quickly,
BAS automatically boosts the braking force,
thus shortening the stopping distance.
X Keep the brake pedal firmly depressed until
the emergency braking situation is over.
ABS prevents the wheels from locking.
The brakes will function as usual once you
release the brake pedal. BAS is deactivated. G
WARNING
If BAS has malfunctioned, the braking system
remains available with full brake boosting
effect. However, braking force is not auto-
matically increased in emergency braking sit-
uations and the stopping distance may
increase. BAS PLUS (Brake Assist System Plus)
BAS PLUS is only available on vehicles with
DISTRONIC PLUS. 54
Driving safety systemsSafety

or brake discs, depends on the individual driv-
ing style and operating conditions.
For this reason, it is impossible to state a
mileage that will be valid under all circum-
stances. An aggressive driving style will lead
to high wear. You can obtain further informa-
tion about this from your Mercedes-Benz
Service Centre. Tyre traction
G
WARNING
Whereas the vehicle can be fully controlled at
a certain speed on dry roads, you must reduce
your speed on wet or icy roads to achieve the
same road safety. You could otherwise cause
an accident.
Pay particular attention to the road conditions
at temperatures around freezing point.
If ice has formed on the road surface (e.g.
from fog), a thin film of water rapidly forms on
the ice when you brake, considerably reduc-
ing tyre traction. Drive with particular care in
such weather conditions. 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, do not drive in tyre ruts, and
brake carefully. Driving on flooded roads If you have to drive on stretches of road on
which water has collected, please bear in
mind that:
R
the maximum permissible still water depth
is 12 cm.
R you should drive no faster than at walking
pace.
! 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-
age the engine, the electronics or the trans-
mission. Winter driving
Important safety notes G
WARNING
If the vehicle becomes trapped in snow,
ensure that snow is kept away from the
exhaust pipe and from around the vehicle as
long as the engine is running. Otherwise, poi-
sonous carbon monoxide (CO) may enter the
vehicle, resulting in loss of consciousness and
even death.
To assure sufficient fresh air ventilation, open
a window slightly on the side of the vehicle
not facing the wind.
Have your vehicle winterproofed at a qualified
specialist workshop at the onset of winter.
Observe the notes in the "Winter operation"
section (Y page 288).
Driving with summer tyres Observe the notes in the "Winter operation"
section (Y
page 288). 150
Driving tipsDriving and parking

cause the drive wheels to los
etheir grip and
the vehicle could skid.
You can set a variable or permanent limit
speed:
R variable for speed limits, e.g. in built-up
areas
R permanent for long-term speed restric-
tions, e.g. when driving with winter tyres
fitted (Y page 156) G
WARNING
SPEEDTRONIC is only an aid designed to
assist driving. You are responsible for the
vehicle's speed and for braking in good time.
i The speed indicated in the speedometer
may differ slightly from the limit speed
stored.
Variable SPEEDTRONIC General notes
With the cruise control lever, you can operate
cruise control or DISTRONIC PLUS and vari-
able SPEEDTRONIC.
The LIM indicator lamp on the cruise control
lever indicates which system you have selec-
ted:
R LIM indicator lamp off: cruise control or
DISTRONIC PLUS is selected.
R LIM indicator lamp on: variable SPEED-
TRONIC is selected.
You can use the cruise control lever to limit
the speed to any speed above 30 km/h while
the engine is running. :

WARNING
If there is a change of drivers, advise the new
driver of the limit speed stored.
Only use variable SPEEDTRONIC if you will not
have to accelerate suddenly to a speed above
that stored as the limit speed. You could oth-
erwise cause an accident.
You can only exceed the limit speed stored if
you deactivate variable SPEEDTRONIC:
R using the cruise control lever
R by depressing the accelerator pedal
beyond the pressure point (kickdown) 154
Driving systemsDriving and parking

Permanent SPEEDTRONIC
You can use the on-board computer to limit
the speed permanently to avalue between
160 km/h(e.g. for driving on winter tyres) and
the maximum speed ( Ypage 193).
Shortly before the store dspeed is reached, it
appears in the multifunction display.
Permanent SPEEDTRONIC remains active,
even if variable SPEEDTRONIC is deactivated.
You cannot exceed the stored limit speed,
even if you depress the accelerator pedal
beyond the pressure point (kickdown). DISTRONIC PLUS
Important safety notes DISTRONIC PLUS regulates the speed and
automatically helps you maintain the dis-
tance to the vehicle detected in front. DIS-
TRONIC PLUS brakes automatically so that
the set speed is not exceeded.
On long and steep downhill gradients, espe-
cially if the vehicle is laden, you must select
shift range
1,2or 3in good time. By doing
so, you will make use of the braking effec tof
the engine .This relieves the load on the brake
system and prevents the brakes from over-
heating and wearing too quickly.
If DISTRONIC PLUS detects a slower-moving
vehicle in front, your vehicle is braked in order
to maintain the preset distance to the vehicle
in front. G
WARNING
Do not change down for additional engine
braking on a slippery road surface. This could
cause the drive wheels to lose their grip and
the vehicle could skid. G
WARNING
DISTRONIC PLUS is only an aid designed to
assist driving. The driver remains fully respon-
sible for the vehicle's distance from other
vehicles, the vehicle's speed and for braking
in good time. DISTRONIC PLUS does not react in particular
to:
R
pedestrians
R stationary obstacles on the road, e.g. stop-
ped or parked vehicles
R oncoming and crossing traffic
DISTRONIC PLUS may not detect narrow vehi-
cles driving in front,e .g. motorcycles, or vehi-
cles driving on a different line. Therefore,
always pay attention to traffic conditions even
when DISTRONIC PLUS is activated. Other-
wise, you may fail to recognise dangers in
time, cause an accident and injure yourself
and others. G
WARNING
DISTRONIC PLUS cannot take account of road
and traffic conditions. If DISTRONIC doe snot
recognise or no longer recognises the vehicle
in front, do not activate DISTRONIC or, if it is
already active, deactivate it. This is especially
the case:
R before corners
R on filter lanes
R when changing to a lane with faster moving
traffic
R in complex driving situations or where lanes
are diverted, e.g. at roadworks on a motor-
way
DISTRONIC PLUS otherwise maintains the
current speed set by you or accelerates up to
the set speed.
DISTRONIC PLUS cannot take account of
weather conditions. Deactivate, or do not
activate, DISTRONIC PLUS:
R if the roads are slippery, snow-covered or
icy. The wheels could lose their grip when
braking or accelerating. The vehicle could
start to skid.
R if the sensors are dirty or there is poor vis-
ibility, e.g. due to snow, rain or fog. Dis-
tance control may be impaired.
Always pay attention to traffic conditions
even when DISTRONIC PLUS is activated. 156
