on.
Warning!G
Getting out of your vehicle with the gear se-
lector lever* not fully engaged in positionP
(manual transmission: first or reverse gear)
is dangerous. Also, when parked on an in-
cline, positionP (manual transmission: first
or reverse gear) alone may not prevent your
vehicle from moving, possibly hitting people
or objects.
Always set the parking brake in addition to
shifting to positionP (manual transmission:
first or reverse gear).
When parked on an incline, also turn the
front wheels towards the road curb.
Warning!G
When leaving the vehicle, always remove the
SmartKey from the starter switch, take it
with you, and lock the vehicle. Do not leave
children unattended in the vehicle, or with
access to an unlocked vehicle. Children
could release the parking brake and/or
move the gear selector lever* from
positionP (manual transmission: into
Neutral), either of which could result in an
accident and/or serious personal injury.

Although independent systems, their
protective functions work in conjunction
with each other.The SRS system conducts a self-test when
the ignition is switched on and in regular
intervals while the engine is running. This
facilitates detection of malfunctions. The
1indicator lamp in the instrument
cluster comes on when the ignition is
switched on and goes out no later than a
few seconds after the engine has been
started.
The SRS components are in operational
readiness if the 1indicator lamp is not
lit when the engine is running.
A malfunction in the system has been
detected if the 1indicator lamp:

fails to go out after approximately
4 seconds after the engine was started

does not come on at all

comes on after the engine was started
or while driving

72 Safety and Security
Occupant safety
Warning!G
If the 75 indicator lamp illumi-
nates when an adult or someone larger than
a small individual is in the passenger seat,
have the passenger re-position himself or
herself in the seat until the 75
indicator lamp goes out.
More information about air bag display
messages (
page 361).
In the event of a collision, the air bag control
unit will not allow passenger front air bag
deployment when the OCS classified the
passenger seat occupant as being up to or
less than the weight of a typical
12-month-old child in a standard child
restraint or if the passenger seat is sensed
as being empty.
When the OCS senses that the passenger
seat occupant is classified as being up to or
less than the weight of a typical
12-month-old child in a standard child
restraint, the 75 indicator lamp
will illuminate when the engine is started
and remain illuminated, indicating that the
passenger front air bag is deactivated.
When the OCS senses that the passenger
seat is classified as being empty, the
75 indicator lamp will illumi-
nate when the engine is started and remain
illuminated, indicating that the passenger
front air bag is deactivated. When the OCS senses that the passenger
seat occupant is classified as being heavier
than the weight of a typical 12-month-old
child seated in a standard child restraint or
as being a small individual (such as a young
teenager or a small adult), the
75 indicator lamp will illumi-
nate for approximately 6 seconds when the
engine is started and then, depending on
occupant weight sensor readings from the
seat, remain illuminated or go out. With the
75 indicator lamp illuminated,
the passenger front air bag is deactivated.
With the 75 indicator lamp out,
the passenger front air bag is activated.
When the OCS senses that the passenger
seat occupant is classified as an adult or
someone larger than a small individual, the
75 indicator lamp will illumi-
nate for approximately 6 seconds when the
engine is started and then go out, indicating
that the passenger front air bag is activated.

78 Safety and Security
Occupant safety
Enhanced seat belt reminder system
When the engine is started, the seat belt
telltale< will always illuminate
for 6 seconds to remind you and your
passenger to fasten your seat belts.
If the driver’s seat belt is not fastened
when the engine is started, an additional
warning chime will also sound for a maxi-
mum of 6 seconds or until the driver’s seat
belt is fastened.
If after these 6 seconds, the driver’s or the
passenger’s seat belt (with the passenger
seat occupied) are not fastened with both
doors closed,

the seat belt telltale< remains illu-
minated for as long as either the driv-
er’s or passenger’s seat belt is not
fastened.

and if the vehicle speed once exceeds
15 mph (25 km/h), the seat belt
telltale< starts flashing and a
warning chime sounds with increasing intensity for a maximum of 60 seconds
or until both the driver’s and
passenger’s seat belt are fastened.
If the driver’s or the passenger’s seat
belt remains unfastened after
60 seconds, the warning chime stops
sounding. The seat belt telltale<
stops flashing but continues to be
illuminated.
The seat belt telltale< will only go out
if both the driver’s and the passenger’s
seat belt (with the passenger seat occu-
pied) are fastened, or the vehicle is stand-
ing still and a door is opened.
For more information, see the “Practical
hints” section (
page 351).

Seat belts should not be worn twisted.
In a crash, you would not have the full
width of the seat belt to manage impact
forces. The twisted seat belt against
your body could cause injuries.

Pregnant women should also always use
a lap-shoulder belt. The lap belt portion
should be positioned as low as possible
on the hips to avoid any possible
pressure on the abdomen.

Never place your feet on the instrument
panel, dashboard or on the seat. Always
keep both feet on the floor in front of the
seat.

When using a seat belt to secure infant
or toddler restraints or children in
booster seats, always follow the child
seat manufacturer’s instructions.


84 Safety and Security
Driving safety systems
In this section you will find information on
the following driving safety systems:

ABS (Antilock Brake System)

BAS (Brake Assist System)

ESP® (Electronic Stability Program)
ABS
The Antilock Brake System (ABS) regulates
the brake pressure so that the wheels do
not lock during braking. This allows you to
maintain the ability to steer your vehicle.
The ABS is functional above a speed of
approximately 5 mph (8 km/h) indepen-
dent of road surface conditions.
On slippery road surfaces, the ABS will
respond even to light brake pressure.
The -indicator lamp in the instrument
cluster (
page 26) comes on when you
switch on the ignition. It goes out when the
engine is running.
Warning!G
The following factors increase the risk of
accidents:

Excessive speed, especially in turns

Wet and slippery road surfaces

Following another vehicle too closely
The driving systems described in this sec-
tion cannot reduce these risks or prevent
the natural laws of physics from acting on
the vehicle.
Always adjust your driving style to the
prevailing road and weather conditions and
keep a safe distance to other road users and
objects on the street.
iIn winter operation, the maximum
effectiveness of the ABS, the BAS, and the ESP®
is only achieved with winter tires (
page 332)
or snow chains as required.
Warning!G
Do not pump the brake pedal. Use firm,
steady brake pedal pressure instead. Pump-
ing the brake pedal defeats the purpose of
the ABS and significantly reduces braking
effectiveness.

86 Safety and Security
Driving safety systems
BAS
The Brake Assist System (BAS) operates in
emergency situations. If you apply the
brakes very quickly, the BAS automatically
provides full brake boost, thereby poten-
tially reducing braking distance.
Apply continuous full braking pressure
until the emergency braking situation is
over.
The ABS will prevent the wheels from
locking.
When you release the brake pedal, the
brakes function again as normal. The BAS
is then deactivated.
ESP®
The Electronic Stability Program (ESP®) is
operational as soon as the engine is run-
ning and monitors the vehicle’s traction
(force of adhesive friction between the
tires and the road surface) and handling.
The ESP
® recognizes when a wheel is spin-
ning or if the vehicle starts to skid.
By applying the brakes to the appropriate
wheel and by limiting the engine output,
the ESP
® works to stabilize the vehicle.
The ESP® is especially useful while driving
off and on wet or slippery road surfaces.
The ESP
® also stabilizes the vehicle during
braking and steering maneuvers.
The ESP
® warning lampv in the
instrument cluster flashes when the ESP®
is engaged.
The ESP
® warning lampv in the
instrument cluster comes on when you
switch on the ignition. It goes out when the
engine is running.
Warning!G
If the BAS is malfunctioning, the brake
system is still functioning normally, but
without the additional brake boost available
that BAS would normally provide in an emer-
gency braking maneuver. Therefore, the
braking distance may increase.
Warning!G
The BAS cannot prevent the natural laws of
physics from acting on the vehicle, nor can
it increase braking efficiency beyond that
afforded by the condition of the vehicle
brakes and tires or the traction afforded.
The BAS cannot prevent accidents, includ-
ing those resulting from excessive speed in
turns, following another vehicle too closely,
or hydroplaning. Only a safe, attentive, and
skillful driver can prevent accidents.
The capabilities of a BAS equipped vehicle
must never be exploited in a reckless or
dangerous manner which could jeopardize
the user’s safety or the safety of others.

87 Safety and Security
Driving safety systems
For more information, see the “Practical
hints” section (
page 350) and
(
page 359).
Warning!G
Never switch off the ESP® when you see the
ESP®warning lampv flashing in the in-
strument cluster. In this case, proceed as
follows:

While driving off, apply as little throttle
as possible.

While driving, ease up on the accelera-
tor.

Adapt your speed and driving style to
the prevailing road conditions.
Failure to observe these guidelines could
cause the vehicle to skid.
The ESP
® cannot prevent accidents result-
ing from excessive speed.
Warning!G
The ESP® cannot prevent the natural laws of
physics from acting on the vehicle, nor can
it increase the traction afforded. The ESP
®
cannot prevent accidents, including those
resulting from excessive speed in turns, or
hydroplaning. Only a safe, attentive, and
skillful driver can prevent accidents. The ca-
pabilities of an ESP
® equipped vehicle must
never be exploited in a reckless or danger-
ous manner which could jeopardize the us-
er’s safety or the safety of others.
!Because the ESP® operates automatically,
the engine must be turned off (SmartKey in
starter switch position0 or1) when

the parking brake is being tested on a brake
test dynamometer

the vehicle is being towed with the front axle
raised
Active braking action through the ESP
® may
otherwise seriously damage the brake system.
iThe ESP® will only function properly if you
use wheels of the recommended tire size
(
page 434).

88 Safety and Security
Driving safety systems
Electronic traction system
The electronic traction system is a
component of ESP
®.
The electronic traction system improves
the vehicle’s ability to utilize available
traction, especially under slippery road
conditions by applying the brakes to a
spinning wheel.
When you switch off the ESP
®, the
electronic traction system is still enabled.Switching off the ESP
®
To improve the vehicle’s traction, turn off
the ESP® in driving situations where it
would be advantageous to have the drive
wheels spin and thus cut into surfaces for
better grip such as:

when driving with snow chains

in deep snow

in sand or gravelWhen you switch off the ESP
®

the ESP® does not stabilize the vehicle

the engine output is not limited, which
allows the drive wheels to spin and
thus cut into surfaces for a better grip

the traction control will still apply the
brakes to a spinning wheel

the ESP® continues to operate when
you are braking

you cannot activate the cruise control

the cruise control switches off if
currently activated
Warning!G
If you are driving too fast, the electronic
traction system cannot reduce the risk of an
accident.
The electronic traction system cannot pre-
vent the natural laws of physics from acting
on the vehicle.
Warning!G
The ESP® should not be switched off during
normal driving other than in the circum-
stances described below. Disabling of the
system will reduce vehicle stability in stan-
dard driving maneuvers.
Do not switch off the ESP
® when a spare
wheel is mounted.
Warning!G
Switch on the ESP® immediately if the afore-
mentioned circumstances do not apply any-
more. Otherwise the ESP
® will not stabilize
the vehicle when it is starting to skid or a
wheel is spinning.

89 Safety and Security
Driving safety systems
The ESP® switch is located on the upper
part of the center console.
1ESP
® switch
With the engine running, press ESP®
switch1 until the ESP® warning
lampv in the instrument cluster
comes on.
The ESP
® is switched off.Switching on the ESP
®

Press ESP® switch1 until the ESP®
warning lampv in the instrument
cluster goes out.
You are now again in normal driving
mode with the ESP
® switched on.
iWhen the ESP® is switched off and one
or more drive wheels are spinning, the
ESP
®warning lampv in the instrument
cluster flashes. However, the ESP® will then not
stabilize the vehicle.
Warning!G
When the ESP® warning lampv is illumi-
nated continuously, the ESP® is switched off
or is not operational due to a malfunction.
Vehicle stability in standard driving maneu-
vers reduces.
Adapt your speed and driving to the prevail-
ing road conditions and to the non-operating
status of the ESP
®.
!Avoid spinning of a drive wheel for an
extended period with the ESP® switched off. This
may cause serious damage to the drivetrain
which is not covered by the Mercedes-Benz
Limited Warranty.
