Lower anchors and tethers for children
(LATCH) (
page 64)
Additional protection potential provide
Supplemental Restraint System (SRS)

®) (page 60)Air bag system components with
The front passenger front air bag off in-
dicator lamp (
page 53)
Front passenger seat with Occupant
Classification System (OCS)
(page 50)
As 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 early detection of malfunctions.
The =indicator lamp in the instrument
cluster (page 28) comes on when the
ignition is switched on and goes out no lat-
er than a few seconds after the engine has
been started.The SRS components are in operational
readiness when the =indicator lamp is
not lit when the engine is running.
A malfunction in the system has been
detected if the =indicator lamp:
fails to go out not later than approxi-
mately 4 seconds after the engine was
started
does not come on at all
comes on after the engine was started
or while driving
i
For information on infants and children trav-
eling with you in the vehicle and restraint sys-
tems for infants and children, see “Children in
the vehicle” (
page 61).
Warning!
G
Modifications to or work improperly con-
ducted on restraint systems (such as seat
belts and anchors, emergency tensioning
devices, seat belt force limiters or air bags)
or their wiring, as well as tampering with in-
terconnected electronic systems, can lead
to the restraint systems no longer function-
ing as intended.

51 Safety and Security
Occupant safety
Both driver and the front passenger should
always use the 59indicator
lamp as an indication of whether or not the
front passenger is properly positioned.Warning!
G
If the 59indicator lamp illumi-
nates when an adult or someone larger than
a small individual is in the front passenger
seat, have the front passenger re-position
himself or herself in the seat until the
59indicator lamp goes out, or
check whether objects are caught under or
around the seat.
More information about air bag display mes-
sages (
page 562).
In the event of a collision, the air bag control
unit will not allow front passenger front air
bag deployment when the OCS classified
the front passenger seat occupant as being
up to or less than the weight of a typical
12-month-old child in a standard child re-
straint or if the front passenger seat is
sensed as being empty.
When the OCS senses that the front passen-
ger 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 59indicator
lamp will illuminate when the engine is start-
ed and remain illuminated, indicating that
the front passenger front air bag is deacti-
vated.
When the OCS senses that the front passen-
ger seat is classified as being empty, the
59indicator lamp will illumi-
nate when the engine is started and remain
illuminated, indicating that the front
passenger front air bag is deactivated.
When the OCS senses that the front passen-
ger 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 59indicator lamp will illu-
minate 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 59indicator lamp illumi-
nated, the front passenger front air bag is
deactivated. With the 59 indi-
cator lamp out, the front passenger front air
bag is activated.
When the OCS senses that the front passen-
ger seat occupant is classified as an adult or
someone larger than a small individual, the
59indicator lamp will illumi-
nate for approximately 6 seconds when the
engine is started and then go out, indicating
that the front passenger front air bag is
activated.
If the 59indicator lamp is illu-
minated, the front passenger front air bag is
deactivated and will not be deployed.
If the 59indicator lamp is not
illuminated, the front passenger front air
bag is activated and will be deployed:
in the event of certain frontal impacts
if impact exceeds a preset deployment
threshold

Seat belts
When the engine is started, the seat belt
telltale< illuminates for a maximum of
6 seconds and a warning chime sounds to
remind you and your passengers to fasten
your seat belts.
If after these 6 seconds, the driver’s or the
front passenger’s seat belt (with the front
passenger seat occupied) are not fastened
with all doors closed,
and the vehicle speed does not exceed
15 mph (25 km/h), the seat belt
telltale< remains illuminated for as
long as either the driver’s or front
passenger’s seat belt is not fastened.
and the vehicle speed exceeds
15 mph (25 km/h), the seat belt
telltale< starts flashing and a
warning chime sounds with increasing
intensity until both the driver’s and
front passenger’s seat belt are fas-
tened, or for a maximum of 60 seconds
from the time the vehicle speed exceeded 15 mph (25 km/h) if either
the driver’s or front passenger’s seat
belt remains unfastened.
If the driver’s or front passenger’s seat
belt remains unfastened after
60 seconds, the seat belt telltale<
stops flashing and the warning chime
stops sounding. The seat belt
telltale< then continues to be illu-
minated for as long as either the driv-
er’s or front passenger’s seat belt are
not fastened.
The seat belt telltale< will only go out
if both the driver’s and the front passen-
ger’s seat belt (with the front passenger
seat occupied) are fastened, or the vehicle
is standing still and a front door is opened.
For more information, see “Practical hints”
(
page 550).
Always wear your seat belt. All vehicle
occupants always need to have their seat
belts fastened and wear them properly.
Warning!
G
Never place anything between seat cushion
(e.g. pillow), since it reduces the effective-
ness of the Occupant Classification System.
The bottom of the child seat must make full
contact with the passenger seat cushion. An
incorrectly mounted child seat could cause
injuries to the child in case of an accident,
instead of increasing protection for the
child.
Follow the manufacturer’s instructions for
installation of child seats.

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 ap-
proximately 5 mph (8 km/h) independent
of road surface conditions.
On slippery road surfaces, the ABS will re-
spond even to light brake pressure.
The - indicator lamp in the instrument
cluster (
page 28) comes on when you
switch on the ignition (
page 315). It goes
out when the engine is running.
Braking
At the instant one of the wheels is about to
lock up, a slight pulsation can be felt in the
brake pedal, indicating that the ABS is in
the regulating mode.
Keep firm and steady pressure on the
brake pedal while experiencing the pul-
sation.
Continuous, steady brake pedal pressure
yields the advantages provided by the ABS,
namely braking power and the ability to
steer the vehicle.
Warning!
G
The following factors increase the risk of ac-
cidents:
Excessive speed, especially in turns
Wet and slippery road surfaces
Following another vehicle too closely
The ABS, BAS, BAS Plus*, EBP, ESP
® and
ETS cannot reduce this risk.
Always adjust your driving style to the pre-
vailing road and weather conditions.i
In winter operation, the maximum effective-
ness of the ABS, Adaptive Brake, BAS,
BAS Plus*, EBP, ESP
® and ETS is only achieved
with winter tires (
page 530), 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.

72 Safety and SecurityDriving safety systemsESP
®
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 ap-
plying 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
maneuvers.
The ESP
® warning lamp v in the instru-
ment cluster flashes when the ESP
® is en-
gaged.
The ESP
® warning lamp v in the instru-
ment cluster comes on when you switch on
the ignition (
page 315). It goes out when
the engine is running.
Warning!
G
When the EBP is malfunctioning, the ABS,
BAS, BAS Plus*, ESP
® and ETS are also
switched off.
If the EBP is malfunctioning, the brake sys-
tem will still function with full brake boost.
However, the rear wheels could lock up dur-
ing emergency braking situations, for exam-
ple. You could lose control of the vehicle and
cause an accident. Adapt your driving style
to the changed driving characteristics.
Warning!
G
Never switch off the ESP
® when you see the
ESP
® warning lamp v flashing in the in-
strument cluster. In this case proceed as fol-
lows:
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.
i
DISTRONIC Plus* is switched off when the
ESP® engages.

ETS
The Electronic Traction System is a compo-
nent of ESP
®.
The Electronic Traction System (ETS) im-
proves the vehicle’s ability to utilize avail-
able traction, especially under slippery road conditions. The brakes are applied to
the spinning wheel and power is trans-
ferred to the wheel(s) with traction.
The ESP
® warning lampvin the instru-
ment cluster starts to flash at any vehicle
speed, as soon as a tire loses traction and
the wheel begins to spin.
When you switch off the ESP
®, the ETS 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 gravel
i
The ESP
® will only function properly if you
use wheels of the recommended tire size
(
page 655).
!
Because of the ESP’s
® automatic operation,
the engine and ignition must be shut off
(SmartKey in starter switch position0 or1 or
KEYLESS-GO start/stop button* in position0
or1) when
the parking brake is being tested on a brake
test dynamometer
the vehicle is being towed with the
front/rear axle raised
Active braking action through the ESP
® may oth-
erwise seriously damage the brake system.
Warning!
G
If you are driving too fast, the Electronic
Traction System cannot reduce the risk of
an accident.
The ETS cannot prevent the natural laws of
physics from acting on the vehicle.i
If the yellow ESP
® warning lampv
comes on while driving, the ETS is being
switched off temporarily to prevent overheating
of the drive wheel brakes. In addition, the mes-
sage “ESP Currently unavailable See Oper. Man-
ual” appears in the multifunction display.
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.
!
Turn the ESP
® on immediately if the afore-
mentioned circumstances do not apply anymore.
i
DISTRONIC Plus* cannot be activated when
the ESP
® has been switched off.
