Driving safety systems overview
In this section, you will find information about
the following driving safety systems:
R ABS (Anti-lock BrakingSystem)
(Y page 65)
R BAS (Brake AssistSystem) (Y page 65)
R BAS PLUS(Brake AssistSystem PLUS)
(Y page 65)
R Adaptive brake lamps (Y page 67)

R ADAPTIVE BRAKE (Y page 69)
R PRE-SAFE ®
Brake (Y page 69) Important safety notes
If you fail to adapt your driving style or if you
are inattentive, the driving safety systems can
neither reduce the risk of accident nor over-
ride the laws of physics. Driving safety sys-
tems are merely aids designed to assist driv-
ing. You are responsible for the distance to
the vehicle in front, for vehicle speed and for
braking in good time. Always adapt your driv-
ing style to suit the prevailing road and
weather conditions and maintain a safe dis-
tance from the vehicle in front. Drive care-
fully.
i The driving safety systems described only
work as effectively as possible when there
is adequate contact between the tyres and
the road surface. Please pay special atten-
tion to the notes on tyres, recommended
minimum tyre tread depths, etc.
(Y page 340).
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. 64

ysystemsSafety

Only deactivate ESP
®
in the situations descri-
bed in the following.
X To deactivate:(Y page 240).
The å ESP®
OFF warning lamp in the
instrument cluster lights up.
X To activate: (Ypage 240).
The å ESP®
OFF warning lamp in the
instrument cluster goes out.
ESP ®
is activated automaticallyw hen the
engine is started.
The ECO start/stop function switches the
engine off automatically if the vehicle stops
moving. When pulling away again, the engine
starts automatically .ESP ®
remains in its pre-
viously selected status. Example :ifESP®
was
deactivated before the engine was switched
off, ESP ®
remains deactivated when the
engine is switched on again.
If ESP ®
is deactivated and one or more wheels
star tto spin, the ÷ESP®
warning lamp in
the instrument cluster flashes. In such situa-
tions, ESP ®
will not stabilise the vehicle.
It may be best to deactivate ESP ®
in the fol-
lowing situations:
R when using snow chains
R in deep snow
R on sand or gravel
If you deactivate ESP ®
:
R ESP ®
no longer improves driving stability.
R traction control is still activated.
R ESP ®
still provides support when you
brake.
R engine torque is not limited and the drive
wheels are able to spin. The spinning of the
wheels results in a cutting action for better
traction.
ESP ®
trailer stabilisation G
WARNING
If road and weather conditions are poor,
trailer stabilisation will not be able to prevent the vehicle/trailer combination from swerv-
ing. Trailers with a high centre of gravity can
tip over before ESP
®
can detect this. There is
a risk of an accident.
Always adapt your driving style to the prevail-
ing road and weather conditions.
If your vehicle/trailer combination begins to
lurch, you can only stabilise the vehicle/
trailer combination by depressing the brake
firmly.
In this situation, ESP ®
assists you and can
detect if the vehicle/trailer combination
begins to lurch. ESP ®
slows the vehicle down
by braking and limiting the engine output until
the vehicle/trailer combination has stabi-
lised.
Trailer stabilisation is active above speeds of
about 65 km/h.
Trailer stabilisation does not work if ESP ®
is
deactivated or disabled because of a mal-
function. EBD (electronic brake force distribu-
tion)
i Observe the "Important safety notes" sec-
tion (Y page 64). G
WARNING
If EBD has malfunctioned, the rear wheels can
still lock, e.g. under full braking. This increa-
ses 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 dis-
play messages (Y page 252).
EBD monitors and controls the brake pres-
sure on the rear wheels to improve driving
stability while braking. 68
Driving safety systemsSafety

Winter driving
Important safety notes G
WARNING
If you shift dow nonaslippery road surface in
an attempt to increase the engine's braking
effect, the drive wheels could lose their grip.
This increases the risk of skidding and having
an accident.
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.
Have your vehicle winterproofed at a qualified
specialist workshop at the onset of winter.
Observe the notes in the "Winter operation"
section (Y page 342).
Driving with summer tyres Observe the notes in the "Winter operation"
section (Y page 342).
Slippery road surfaces 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.
This increases the risk of skidding and having
an accident.
Do not shift down for additional engine brak-
ing on a slippery road surface. If the vehicle threatens to skid or cannot be
stopped when moving at low speed:
X
Vehicles with manual transmission:
shift to neutral.
X Vehicles with automatic transmission:
shift the transmission to position N.
X Try to bring the vehicle under control by
using corrective steering.
You should drive particularly carefully on slip-
pery road surfaces. Avoid sudden accelera-
tion, steering and braking manoeuvres.
i For more information on driving with
snow chains, see (Y page 343). Driving systems
Cruise control
Important safety notes 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
Cruise control cannot take account of road
and traffic conditions.
Always pay attention to traffic conditions
even when cruise control is activated.
Cruise control is only an aid designed to assist
driving. You are responsible for the vehicle's
speed and for braking in good time. G
WARNING
Do not use cruise control
R in traffic conditions that do not allow you to
drive at a constant speed (e.g. heavy traffic 182
Driving systemsDriving and parking

G
WARNING
Make sure that no persons or animals are in
the manoeuvring range. Otherwise, they
could be injured.
! If unavoidable, you should drive over
obstacles such as kerbs slowly and not at
a sharp angle .Otherwise, you may damage
the wheels or tyres.
Parking Guidance is an electroni cparking aid
with ultrasound. Ultrasound is used to meas-
ure the road on both sides of the vehicle .A
suitable parking space is indicated by the
parking symbol. You receive steering instruc-
tions when parking. You may also use PARK-
TRONIC (Y page 200).
When PARKTRONIC is deactivated, Parking
Guidance is also unavailable.
Use Parking Guidance for parking spaces:
R that are parallel to the direction of travel
R that are on straight roads, not bends
R that are on the same level as the road, i.e.
not on the pavement, for example. Parking
Guidance may not detect flat kerbs
Parking tips:
R on narrow roads, drive as closely as possi-
ble past the parking space.
R parking spaces that are littered, overgrown
or partially occupied by trailer drawbars
might be identified incorrectly or not at all.
R snowfall or heavy rain may lead to a parking
space being measured inaccurately.
R pay attention to the PARKTRONIC
(Y page 201) warning messages during the
parking procedure.
R when transporting a load which protrudes
from your vehicle, you must not use Parking
Guidance.
R never use Parking Guidance with snow
chains or an emergency spare wheel fitted. R
make sure that the tyre pressures are
always correct.T his hasadirec teffect on
the steering instructions.
R the way you rvehicle is positioned in the
parking space after parkin gis dependent
on various factors. These include the posi-
tion and shape of the vehicles parked in
front and behind it and the conditions of the
location. In some cases, Parking Guidance
may guide you too far or not far enough into
a parking space. In some cases, it may also
lead you across or onto the kerb. If neces-
sary, cancel the parking procedure with
Parking Guidance.
Detecting parking spaces Example: vehicles with automatic transmission
:
Detected parking space on the left
; Parking symbol
= Detected parking space on the right
Parking Guidance is automatically activated
when you drive forwards. The system is
operational at speeds of up to approximately
35 km/h. While in operation, the system inde-
pendently locates and measures parking
spaces on both sides of the vehicle. When
driving at speeds below 30 km/h, you will see
parking symbol ;as a status indicator in the
instrument cluster.
When a parking space has been detected, an
arrow towards the right =or the left :also
appears. Parking Guidance only displays
parking spaces on the front-passenger side
as standard. Parking spaces on the driver's
side are displayed as soon as the turn signal
on the driver's side is activated. To park on
the driver's side, you must leave the driver's
side turn signal switched on until you have
engaged reverse gear. 204

Snow chains
G
WARNING
If you have fitted snow chains to the front
wheels, they may scrape against the vehicle
body or chassis components. This could
cause damage to the vehicle or the tyres.
There is a risk of an accident.
To avoid hazardous situations:
R never fit snow chains on the front wheels
R fit snow chains to the rear wheels in pairs.
! Vehicles with steel wheels: if you wish
to fit snow chains to steel wheels, make
sure that you remove the respective
wheels' hubcaps first. The hubcaps may
otherwise be damaged.
For safety reasons, Mercedes-Benz recom-
mends that you only use snow chains that
have been specially approved for your vehicle
by Mercedes-Benz, or that are of a corre-
sponding standard of quality.
If you intend to fit snow chains, please bear
the following points in mind:
R snow chains cannot be fitted to all wheel-
tyre combinations. Permissible wheel-tyre
combinations (Y page 350).
R only use snow chains when the road sur-
face is completely snow-covered. Remove
the snow chains as soon as possible when
you come to a road that is not snow-cov-
ered.
R local regulations may restrictt he use of
snow chains. Observe the appropriate reg-
ulations if you wish to fit snow chains.
R do not exceed the maximum permissible
speed of 50 km/h.
i You may wish to deactivate ESP ®
when
pulling away with snow chains fitted
(Y page 67). This way you can allow the
wheels to spin in a controlled manner, ach-
ieving an increased driving force (cutting
action).
For more information on driving with an emer-
gency spare wheel, see (Y page 363). Tyre pressure
Tyre pressure specifications
G
WARNING
Tyres with too low or too high tyre pressure
contain the following hazards:
R they can burst, in particular if the vehicle is
heavily laden or when driven at high
speeds.
R the tyres can wear excessively and/or
unevenly, which can severely impair tyre
traction.
R the driving, steering and braking character-
istics may be severely impaired.
There is a risk of accident.
Follow recommended tyre inflation pressures
and check the pressure of all the tyres includ-
ing the spare wheel:
R at least every two weeks
R if the load changes
R before beginning a long journey
R for changed operating conditions, e.g. off-
road driving
If necessary, correct the tyre pressure. G
WARNING
If you fit unsuitable accessories onto tyre
valves, the tyre valves may be overloaded and
malfunction, which can cause tyre pressure
loss. Due to their design, retrofitted tyre pres-
sure monitors keep the tyre valve open. This
can also result in tyre pressure loss. There is
a risk of accident.
Only screw standard valve caps or valve caps
specifically provided by Mercedes-Ben zfor
your vehicle onto the tyre valve. G
WARNING
If the tyre pressure drops repeatedly, the
wheel, valve or tyre may be damaged. Tyre
pressure that is too low may result in a tyre
blow-out. There is a risk of accident. Tyre pressure

message will appear in the multifunction dis-
play.
The tyre pressure warning system does not
warn you of an incorrectly set tyre pressure.
Observe the notes on the recommended tyre
pressure (Y page 343).
The tyre pressure loss warning system does
not replace the need to regularly check your
vehicle's tyre pressures, since an even loss of
pressure on several tyres at the same time
cannot be detected by the tyre pressure loss
warning system.
The tyre pressure monitor is not able to warn
you of a sudden loss of pressure, e.g. if the
tyre is penetrated by a foreign object. In the
event of a sudden loss of pressure, bring the
vehicle to a haltb y braking carefully. Avoid
abrupt steering manoeuvres.
The function of the tyre pressure loss warning
system is limited or delaye dif:
R snow chains are fitted to you rvehicle's
tyres.
R road conditions are wintry.
R you are driving on sand or gravel.
R you adopt a very sporty driving style (cor-
nering at high speeds or driving with high
rates of acceleration).
R you are towing a very heavy or large trailer.
R you are driving with a heavy load (in the
vehicle or on the roof).
Restarting the tyre pressure loss warn-
ing system Restart the tyre pressure loss warning system
if you have:
R changed the tyre pressure
R changed the wheels or tyres
R fitted new wheels or tyres
X Before restarting, make sure that the tyre
pressures are set properly on all four tyres
for the respective operating conditions.
The recommended tyre pressures can be
found in the table on the fuel filler flap. The
tyre pressure loss warning system can only give reliable warnings if you have set the
correct tyre pressure. If an incorrect tyre
pressure is set, these incorrect values will
be monitored.
