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 61)
R BAS (Brake Assist System) (Y page 62)
R BAS PLUS (Brake Assist System Plus)
(Y page 62)
R ESP ®
(Electronic StabilityProgram)

R ADAPTIVE BRAKE (Y page 67)
R PRE-SAFE ®
Brake (Y page 67) Important safety notes
If you fail to adapt your driving style or
become distracted, the driving safety sys-
tems can neither reduce the risk of accident
nor override the laws of physics. Driving
safety systems are merely aids designed to
assist driving. You are responsible for the dis- tance to the vehicle in front, for vehicle speed
and for braking in good time. Always adapt
your driving style to suit the prevailing road
and weather conditions and maintain a safe
distance 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 tires and
the road surface. Please pay special atten- tion to the notes on tires, recommended
minimum tire tread depths, etc.
(Y page 310).
In wintry driving conditions, always use
winter tires (M+S tires) 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)
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 vehi-
cle when braking.
The yellow 0025ABS warning lamp in the
instrument cluster lights up when the ignition is switched on. It goes out when the engine is
running.
Important safety notes i
Observe the "Important safety notes" sec-
tion (Y page 61). 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 245) and
display messages which may be shown in the
instrument cluster (Y page 213).
ABS works from a speed of about 5 mph
(8 km/ h), regardless of road-surface condi-
tions. ABS works on slippery surfaces, even if
you only brake gently.
Braking 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. Driving safety systems
61Safety Z

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
i Activate ESP ®
as soon as the situations
described above no longer apply. ESP ®
will
otherwise not be able to stabilize the vehi-
cle if the vehicle starts to skid or a wheel
starts to spin.
! Avoid spinning the driven wheels for an
extended period with ESP ®
deactivated.
You could otherwise damage the drivetrain.
Deactivating/activating ESP ®X
To switch off: press button0043.
The 00BB ESP®
OFF warning lamp in the
instrument cluster lights up.
X To switch on: press button0043.
The 00BB ESP®
OFF warning lamp in the
instrument cluster goes out.
Characteristics when ESP ®
is deactivated
If ESP ®
is deactivated and one or more wheels
start to spin, the 00E5ESP®
warning lamp in
the instrument cluster flashes. In such situa-
tions, ESP ®
will not stabilize the vehicle.
If you deactivate ESP ®
:
R ESP ®
no longer improves driving stability.
R engine torque is no longer limited and the
drive wheels are able to spin. The spinning of the wheels results in a cut-
ting action for better traction on loose sur- faces.
R traction control is still activated.
R ESP ®
still provides support when you
brake.
Deactivating/activating ESP ®

WARNING
When SPORT handling mode is activated,
there is a greater risk of skidding and acci-
dents.
Only activate SPORT handling mode in the sit- uations described in the following. G
WARNING
If you deactivate ESP ®
, ESP ®
no longer sta-
bilizes the vehicle. There is an increased risk
of skidding and an accident.
Only deactivate ESP ®
in the situations descri-
bed in the following.
In the following situations, it may be better to activate SPORT handling mode or deactivate
ESP ®
:
R when using snow chains
R in deep snow
R on sand or gravel
R on designated roads when the vehicle's
own oversteering and understeering char-
acteristics are desired Driving safety systems

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.
Have your vehicle winter-proofed at a quali-
fied specialist workshop at the onset of win-
ter.
Drive particularly carefully on slippery road
surfaces. Avoid sudden acceleration, steering and braking maneuvers. Do not use cruise
control.
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.
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 freez-
ing point do not guarantee that the road sur-
face is free of ice. The road may still be icy, especially in wooded areas or on bridges. The
vehicle could skid if you fail to adapt your
driving style. Always adapt your driving style
and drive at a speed to suit the prevailing
weather conditions.
You should pay special attention to road con-
ditions when temperatures are around freez-
ing point.
For more information on driving with snow
chains, see (Y page 313).
For more information on driving with summer tires, see (Y page 312).
Observe the notes in the "Winter operation"
section (Y page 312). Driving systems
Cruise control
General notes Cruise control maintains a constant road
speed for you. It brakes automatically in order
to avoid exceeding the set speed. On long and
steep downhill gradients, especially if the
vehicle is laden, you must select a lower gear in good time. By doing so, you will make use of the braking effect of the engine. This relievesthe 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 canstore any road speed above 20 mph
(30 km/h).
Important safety notes If you fail to adapt your driving style, cruise
control can neither reduce the risk of an acci-
dent 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 dis-
tance to the vehicle in front, for vehicle speed, Driving systems
169Driving and parking Z

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 curbs
Parking tips:
R On narrow roads, drive as close to the park-
ing space as possible.
R Parking spaces that are littered or over-
grown might be identified or measured
incorrectly.
R Parking spaces that are partially occupied
by trailer drawbars might not be identified
as such or be measured incorrectly.
R Snowfall or heavy rain may lead to a parking
space being measured inaccurately.
R Pay attention to the PARKTRONIC
(Y page 184) 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 moun-
ted.
R Make sure that the tire pressures are
always correct. This has a direct effect on
the steering instructions.
R The way your vehicle is positioned in the
parking space after parking is 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 curb. If neces-
sary, cancel the parking procedure with
Parking Guidance. Detecting parking spaces 0043
Detected parking space on the left
0044 Parking symbol
0087 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
22 mph (35 km/h). While in operation, the
system independently locates and measures
parking spaces on both sides of the vehicle.
When driving at speeds below 19 mph
(30 km/h), you will see parking symbol 0044as
a status indicator in the instrument cluster.
When a parking space has been detected, an arrow towards the right 0087or the left 0043also
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.
Parking Guidance will only detect parking
spaces:
R that are parallel to the direction of travel
R that are at least 5 ft (1.5 m) wide
R that are at least 4.3 ft (1.3 m) longer than
your vehicle
A parking space is displayed while you are
driving past it, and until you are approx-
imately 50 ft (15 m) away from it. 186

vide the best possible grip in wintry road con-
ditions.
Only these tires will allow driving safety sys-
tems such as ABS and ESP ®
to function opti-
mally in winter. These tires have been devel-
oped specifically for driving in snow.
Use M+S tires of the same make and tread on all wheels to maintain safe handling charac-
teristics.
Always observe the maximum permissible
speed specified for the M+S tires you have
mounted.
When you have mounted M+S tires:
X Check the tire pressures (Y page 317).
X Vehicles for USA: restart the tire pressure
monitor (Y page 318).
X Vehicles for Canada: restart the tire pres-
sure loss warning system (Y page 318).
For more information on driving with the
emergency spare wheel, see (Y page 341).Snow chains
G
WARNING
If snow chains are installed to the front
wheels, they may drag against the vehicle
body or chassis components. This could
cause damage to the vehicle or the tires.
There is a risk of an accident.
To avoid hazardous situations:
R never install snow chains to the front
wheels
R always install snow chains in pairs to the
rear wheels.
! You must drive at raised vehicle level
(height 1) if snow chains have been instal-
led. The vehicle may otherwise be dam-
aged.
! On some tire sizes there is not enough
space for snow chains. To avoid damage to
the vehicle or tires, observe the "Wheel and tire combinations" section under "Tires and
wheels". !
Vehicles with steel wheels:
if you
mount snow chains on steel wheels, you
may damage the hub caps. Remove the hub caps from the relevant wheels before
mounting the snow chains.
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 are of a corresponding standard of quality.
If you intend to mount snow chains, please
bear the following points in mind:
R Snow chains may not be mounted on all
wheel/tire combinations. Permissible
wheel-tire combinations (Y page 337).
R Only use snow chains when driving on
roads completely covered by snow.
Remove the snow chains as soon as possi-
ble when you come to a road that is not
snow-covered.
R Local regulations may restrict the use of
snow chains. Observe the appropriate reg-
ulations if you wish to install snow chains.
R Do not exceed the maximum permissible
speed of 30 mph (50 km/h).
i You may wish to deactivate ESP ®
when
pulling away with snow chains installed
(Y page 64). You can thereby allow the
wheels to spin in a controlled manner, ach-
ieving an increased driving force (cutting
action).
For more information on driving with the
emergency spare wheel, see (Y page 341). Winter operation

when adjusting the tire pressure
(Y
page 314).
i The actual values for tires are vehicle-
specific and may deviate from the values in
the illustration. Checking the tire pressures
Important safety notes Observe the notes on tire pressure
(Y
page 314).
Information on air pressure for the tires on
your vehicle can be found:
R on the vehicle's Tire and Loading Informa-
tion placard on the B-pillar
R on the tire pressure label on the fuel filler
flap
R in the "Tire pressure" section
Checking tire pressures manually To determine and set the correct tire pres-
sure, proceed as follows:
X Remove the valve cap of the tire that is to
be checked.
X Press the tire pressure gauge securely onto
the valve.
X Read the tire pressure and compare it with
the recommended value on the Tire and
Loading Information placard (Y page 314).
X If the tire pressure is too low, increase it to
the recommended value.
X If the tire pressure is too high, release air by
pressing down the metal pin in the valve.
Use the tip of a pen, for example. Then,
check the tire pressure again using the tire
pressure gauge.
X Screw the valve cap onto the valve.
X Repeat these steps for the other tires. Tire pressure loss warning system
(Canada only)
General notes While the vehicle is in motion, the tire pres-
sure loss warning system monitors the set
tire pressure using the rotational speed of the wheels. This enables the system to detect
significant pressure loss in a tire. If the speed
of rotation of a wheel changes as a result of a loss of pressure, a corresponding warning
message will appear in the multifunction dis- play.
You can recognize the tire pressure loss warn-
ing by the Run Flat Indicator Active Run Flat Indicator Active
Press 'OK' to Restart
Press 'OK' to Restart message which
appears in the Service
Servicemenu of the multi-
function display. Information on the message
display can be found in the "Restarting the tire
pressure loss warning system" section
(Y page 318).
Important safety notes The tire pressure warning system does not
warn you of an incorrectly set tire pressure.
Observe the notes on the recommended tire
pressure (Y page 314).
The tire pressure loss warning does not
replace the need to regularly check the tire
pressure. An even loss of pressure on several tires at the same time cannot be detected by
the tire pressure loss warning system.
The tire pressure monitor is not able to warn
you of a sudden loss of pressure, e.g. if the
tire is penetrated by a foreign object. In the
event of a sudden loss of pressure, bring the
vehicle to a halt by braking carefully. Avoid
abrupt steering maneuvers.
The function of the tire pressure loss warning system is limited or delayed if:
R snow chains are mounted on your vehicle's
tires.
R road conditions are wintry.
R you are driving on sand or gravel. Tire pressure
