Occupant Classification System opera-
tion (OCS)
PASSENGER AIR BAG OFF indicator lamp:
shows you whether the front-passenger front
air bag is deactivated.
XTurn the SmartKey to position 1or 2in the
ignition lock or on vehicles with KEYLESS-
GO, press the Start/Stop button once or
twice.
The system carries out self-diagnostics.
The PASSENGER AIR BAG OFF indicator lamp
must light up for approximately six seconds.
The PASSENGER AIR BAG OFF indicator lamp
then displays the status of the front-
passenger front air bag. If the status of the
front-passenger front air bag changes while
the vehicle is in motion, an air bag display
message may appear in the instrument clus-
ter (
Ypage 301). When the front-passenger
seat is occupied, always pay attention to the
PASSENGER AIR BAG OFF indicator lamp. Be
aware of the status of the front-passenger
front air bag both before and during the jour-
ney.
If the PASSENGER AIR BAG OFF indicator
lamp:
Ris lit: the front-passenger front air bag is
deactivated. It will then not be deployed in
the event of an accident.
Rdoes not light up: the front-passenger
front air bag is enabled. If, in the event of an
accident, all deployment criteria are met,
the front-passenger front air bag is
deployed.
GWARNING
If the PASSENGER AIR BAG OFF indicator
lamp is lit, the front-passenger front air bag is
disabled. It will not be deployed in the event of
an accident and cannot perform its intended
protective function. A person in the front-
passenger seat could then, for example, come
into contact with the vehicle's interior, espe-
cially if the person is sitting too close to the
dashboard. This poses an increased risk of
injury or even fatal injury.
When the front-passenger seat is occupied,
always ensure that:
Rthe classification of the person in the front- passenger seat is correct and the front-
passenger front air bag is enabled or disa-
bled in accordance with the person in the
front-passenger seat
Rthe front-passenger seat has been moved
back as far back as possible.
Rthe person is seated correctly.
Make sure, both before and during the jour-
ney, that the status of the front-passenger
front air bag is correct.
GWARNING
If you secure a child in a child restraint system on the front-passenger seat and the
PASSENGER AIR BAG OFF indicator lamp is
off, the front-passenger front air bag can
deploy in the event of an accident. The child
could be struck by the air bag. This poses an
increased risk of injury or even fatal injury.
Make sure that the front-passenger front air
bag has been disabled. The PASSENGER AIR
BAG OFF indicator lamp must be lit.
54Occupant safety
Safety

If the driver's air bag deploys, this does not
mean that the front-passenger front air bag
will also deploy. The Occupant Classification
System (OCS) categorizes the occupant in the
front-passenger seat. Depending on that
result, the front-passenger front air bag is
either enabled or deactivated.
System self-test
GDANGER
If the PASSENGER AIR BAG OFF indicator
lamp does not light up during the system self-
test, then the system is malfunctioning. The
front-passenger front air bag might be trig-
gered unintentionally or might not be trig-
gered at all in the event of an accident with
high deceleration. This poses an increased
risk of injury or even fatal injury.
In this case the front-passenger seat may not
be used. Do not install a child restraint system
on the front-passenger seat. Have the Occu-
pant Classification System (OCS) checked
and repaired immediately at a qualified spe-
cialist workshop.
GDANGER
If the PASSENGER AIR BAG OFF indicator
lamp remains lit after the system self-test, the
front-passenger front air bag is disabled. It will
not be deployed in the event of an accident. In
this case, the front-passenger front air bag
cannot perform its intended protective func-
tion, e.g. when a person is seated in the front-
passenger seat.
That person could, for example, come into
contact with the vehicle's interior, especially
if the person is sitting too close to the dash-
board. This poses an increased risk of injury or
even fatal injury.
When the front-passenger seat is occupied,
always ensure that:
Rthe classification of the person in the front-
passenger seat is correct and the front-
passenger front air bag is enabled or disa-
bled in accordance with the person in the
front-passenger seat
Rthe person is seated properly with a cor-
rectly fastened seatbelt
Rthe front-passenger seat has been moved
back as far back as possible
If the PASSENGER AIR BAG OFF indicator
lamp remains lit when it should not, the front-
passenger seat may not be used. Do not
install a child restraint system on the front-
passenger seat. Have the Occupant Classifi-
cation System (OCS) checked and repaired
immediately at a qualified specialist work-
shop.
GWARNING
Objects between the seat surface and the
child restraint system could affect OCS oper- ation. This could result in the front-passenger
air bag not functioning as intended during an
accident. This poses an increased risk of
injury or even fatal injury.
Do not place any objects between the seat
surface and the child restraint system. The
entire base of the child restraint system must
always rest on the seat cushion of the front-
passenger seat. The backrest of the forward-
facing child restraint system must, as far as
possible, be resting on the backrest of the
front-passenger seat. Always comply with the
child restraint system manufacturer's instal-
lation instructions.
After the system self-test, the PASSENGER
AIR BAG OFF indicator lamp displays the sta-
tus of the front-passenger front air bag
(
Ypage 54).

seats in the second row
Ron the backrests of the seats in the third
row of seats
Before installing a LATCH-type (ISOFIX) child
restraint system on the second row of seats:
XMove the rear seat backrests in the second
row to an upright position (
Ypage 113).
XInstall the LATCH-type (ISOFIX) child
restraint system on both LATCH-type (ISO- FIX) securing rings ;.
ISOFIX is a standardized securing system for
specially designed child restraint systems on
the rear seats. Non-LATCH-type (ISOFIX) child seats may
also be used and can be installed using the
vehicle's seat belt system. Install the child
seat according to the manufacturer's instruc-
tions.
Top Tether
Introduction
Top Tether provides an additional connection
between the child restraint system secured
with a LATCH-type (ISOFIX) child seat mount
and the vehicle. This helps reduce the risk of
injury even further. If the child restraint sys-
tem is equipped with a Top Tether belt, this
should always be used.
Important safety notes
GWARNING
If the rear seats or the rear seat backrests are
not locked, they could fold forwards in the
event of an accident, heavy braking or sudden
changes of direction. As a result, child
restraint systems cannot perform their inten-
ded protective function. Rear seats and rear
seat backrests that are not locked can also
cause additional injuries, e.g. in the event of
an accident. This poses an increased risk of
injury or even fatal injury.
Always lock the rear seats and rear seat
backrests after installing a Top Tether belt.
Observe the lock verification indicator. Adjust the rear seat backrests so that they are in an
upright position.
If the rear seat backrest is not engaged and
locked, this will be shown in the multifunction
display in the instrument cluster.

Safety

Thus, the distance warning function cannot
provide a warning in all critical situations.
There is a risk of an accident.
Always pay careful attention to the traffic sit-uation and be ready to brake.
GWARNING
The distance warning function cannot always
clearly identify objects and complex traffic
situations.
In such cases, the distance warning function
may:
Rgive an unnecessary warning
Rnot give a warning
There is a risk of an accident.
Always pay careful attention to the traffic sit-
uation and do not rely solely on the distance
warning function.
Function
XTo activate/deactivate: activate or deac-
tivate the distance warning function in the
on-board computer (
Ypage 281).
If the distance warning function is not activa-
ted, the æsymbol appears in the assis-
tance graphics display.
The distance warning function can help you to
minimize the risk of a front-end collision with
a vehicle ahead or reduce the effects of such
a collision. If the distance warning function
detects that there is a risk of a collision, you
will be warned visually and acoustically. The
distance warning function cannot prevent a
collision without your intervention.
Starting at a speed of around 4 mph (7 km/h),
the distance warning function warns you if
you rapidly approach a vehicle in front. An
intermittent warning tone will then sound,
and the ·distance warning lamp will light
up in the instrument cluster.
XBrake immediately in order to increase the distance from the vehicle in front.
or
XTake evasive action, provided it is safe to do
so.
Due to the nature of the system, particularly
complicated but non-critical driving condi-
tions may also cause the system to display a
warning.
With the help of the radar sensor system, the
distance warning function can detect obsta-
cles that are in the path of your vehicle for an extended period of time.
Up to a speed of around 40 mph (70 km/h),
the distance warning function can also react
to stationary obstacles, such as stopped or
parked vehicles.
If you approach an obstacle and the distance
warning function detects a risk of a collision,
the system will initially alert you both visually
and acoustically.
In particular, the detection of obstacles can
be impaired if:
Rthere is dirt on the sensors or anything elsecoverin g t
he sensors
Rthere is snow or heavy rain
Rthere is interference by other radar sources
Rthere are strong radar reflections, for
example in parking garages
Ra narrow vehicle traveling in front, e.g. a
motorbike
Ra vehicle traveling in front on a different line
Rnew vehicles or after the COLLISION PRE-
VENTION ASSIST system has been serv-
iced
Observe the notes in the section on break-
ing-in (
Ypage 164).
Following damage to the front end of the vehi-
cle, have the configuration and operation of
the radar sensor checked at a qualified spe-
cialist workshop. This also applies to colli-
sions at low speeds where there is no visible
damage to the front of the vehicle.

ESP®(Electronic Stability Program)
General notes
iObserve the "Important safety notes" sec-
tion (
Ypage 68).
ESP
®monitors driving stability and traction,
i.e. power transmission between the tires and
the road surface.
If ESP
®detects that the vehicle is deviating
from the direction desired by the driver, one
or more wheels are braked to stabilize the
vehicle. The engine output is also modified to
keep the vehicle on the desired course within
physical limits. ESP
®assists the driver when
pulling away on wet or slippery roads. ESP®
can also stabilize the vehicle during braking.
ETS/4ETS (Electronic Traction System)
4ETS traction control is part of ESP®.
Traction control brakes the drive wheels indi-
vidually if they spin. This enables you to pull
away and accelerate on slippery surfaces, for
example if the road surface is slippery on one
side. In addition, more drive torque is trans-
ferred to the wheel or wheels with traction.
Traction control remains active, even if you
deactivate ESP
®.
In appropriate driving situations, activate the
off-road program (
Ypage 258).
Off-road 4ETS (Electronic Traction Sys-
tem)
A 4ETS system specifically suited to off-road
terrain is activated automatically once the off-
road program is activated (
Ypage 258).
Important safety notes
GWARNING
If ESP
®is malfunctioning, ESP®is unable to
stabilize the vehicle. Additionally, further driv-
ing safety systems are deactivated. This
increases the risk of skidding and an accident.
Drive on carefully. Have ESP
®checked at a
qualified specialist workshop.
!Only operate the vehicle for a maximum of
ten seconds on a brake test dynamometer.
Switch off the ignition.
Application of the brakes by ESP
®may oth-
erwise destroy the brake system.
!A function or performance test should
only be carried out on a two-axle dyna-
mometer. Before you operate the vehicle
on such a dynamometer, please consult a
qualified workshop. You could otherwise
damage the drive train or the brake system.
ESP
®is only deactivated if the åwarning
lamp is lit continuously.
If the ÷ warning lamp and the åwarn-
ing lamp are lit continuously, ESP
®is not
available due to a malfunction.
Observe the information on warning lamps
(
Ypage 330) and display messages which
may be shown in the instrument cluster
(
Ypage 291).
iOnly use wheels with the recommended
tire sizes. Only then will ESP®function
properly.

Rthe driver and front-passenger have their
seat belts fastened
and
Rthe vehicle speed is between approx-
imately 4 mph (7 km/h) and 124 mph
(200 km/h)
iIf there is an increased risk of collision,
preventive passenger protection measures
(PRE-SAFE
®) are activated. If the risk of collision with the vehicle in front
remains and you do not brake, take evasive
action or accelerate significantly, the vehicle
may perform automatic emergency braking,
u

p to the point of full brake application. Auto-
matic emergency braking is not performed
until immediately prior to an imminent acci-
dent.
You can prevent the intervention of the PRE-
SAFE
®Brake at any time by:
Rdepressing the accelerator pedal further.
Ractivating kickdown.
Rreleasing the brake pedal.
The braking action of PRE-SAFE
®Brake is
ended automatically if:
Ryou maneuver to avoid the obstacle.
Rthere is no longer any danger of a collision.
Rthere is no longer an obstacle detected in

STEER CONTROL
General information
STEER CONTROL helps you by transmitting a noticeable steering force to the steering
wheel in the direction required for vehicle
stabilization.
This steering assistance is provided in partic-
ular if:
Rboth right wheels or both left wheels are on
a wet or slippery road surface when you
brake.
Rthe vehicle starts to skid.
