regular intervals while the engine is running.
Therefore, malfunctions can be detected in
good time.
The6 restraint system warning lamp in the
instrument cluster lights up when the ignition is
switched on. It goes out no later than a few sec-
onds after the vehicle is started. The compo-
nents of the restraint system are in operational
readiness.
A malfunction has occurred if the 6restraint
system warning lamp:
Rdoes not light up after the ignition is switched
on
Rdoes not go out after a few seconds with the
engine running
Rlights up again while the engine is running
GWARNING
If restraint system is malfunctioning, restraint
system components may be triggered unin-
tentionally or might not be triggered at all in
the event of an accident with a high rate of
vehicle deceleration. This can affect the Emer- gency Tensioning Device or air bag, for exam-
ple. This poses an increased risk of injury or
even fatal injury.
Have the restraint system checked and
repaired in a qualified specialist workshop as
soon as possible.
PASSENGER AIR BAG OFF indicator
lamp
PASSENGER AIR BAG OFF indicator lamp :is
part of the Occupant Classification System
(OCS). The PASSENGER AIR BAG OFF indicator lamp
informs you about the status of the front-
passenger front air bag.
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.
Ris not lit
: 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.
Depending on the person in the front-passenger
seat, the front-passenger front air bag must
either be deactivated or enabled; see the fol-
lowing points. You must make sure of this both
before and during a journey.
RChildren in a child restraint system:
whether the front-passenger front air bag is
enabled or deactivated depends on the instal-
led child restraint system, and the age and
size of the child. Therefore, be sure to observe the notes on the "Occupant Classification
System (OCS)" (
Ypage 48) and on "Chil-
dren in the vehicle" (Ypage 57). There you
will also find instructions on rearward and
forward-facing child restraint systems on the
front-passenger seat.
RAll other persons: depending on the classi-
fication of the person in the front-passenger
seat, the front-passenger front air bag is ena-
bled or deactivated (
Ypage 48). Be sure to
observe the notes on "Seat
belts“ (
Ypage 41) and "Air bags"
(Ypage 45). There you can also find infor-
mation on the correct seat position.
Seat belts
Introduction
Seat belts are the most effective means of
restricting the movement of vehicle occupants
in the event of an accident or the vehicle rolling
over. This reduces the risk of vehicle occupants coming into contact with parts of the vehicle
interior or being ejected from the vehicle. Fur-
thermore, the seat belt helps to keep the vehicle
occupant in the best position in relation to the
air bag.

weather conditions and maintain a safe distance
from the vehicle in front. Drive carefully.
The driving safety systems described only work
as effectively as possible when there is ade-
quate contact between the tires and the road
surface. Please pay special attention to the
notes on tires, recommended minimum tire
tread depths, etc. (
Ypage 285).
In wintry driving conditions, always use winter
tires (M+S tires) and if necessary, snow chains.
Only in this way will the driving 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 vehicle when
braking.
The ! ABS warning lamp in the instrument
cluster lights up when the ignition is switched
on. It goes out when the engine is running.
ABS works from a speed of about 5 mph
(8 km/h), regardless of road-surface conditions.
ABS works on slippery surfaces, even when you
only brake gently.
Important safety notes
iObserve the "Important safety notes" sec-
tion (Ypage 61).
GWARNING
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 (
Ypage 227) and dis-
play messages which may be shown in the
instrument cluster (
Ypage 203).
Braking
XIf ABS intervenes: continue to depress the
brake pedal vigorously until the braking sit-
uation is over.
XTo 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.
The pulsating brake pedal can be an indication
of hazardous road conditions, and functions as a
reminder to take extra care while driving.
BAS (Brake Assist System)
General information
BAS operates in emergency braking situations.
If you depress the brake pedal quickly, BAS
automatically boosts the braking force, thus
shortening the stopping distance.
Important safety notes
iObserve the "Important safety notes" sec-
tion (Ypage 61).
GWARNING
If BAS is malfunctioning, the braking distance
in an emergency braking situation is
increased. There is a risk of an accident.
In an emergency braking situation, depress
the brake pedal with full force. ABS prevents
the wheels from locking.
Braking
XKeep the brake pedal firmly depressed until
the emergency braking situation is over.
ABS prevents the wheels from locking.
The brakes will function as usual once you
release the brake pedal. BAS is deactivated.
BAS PLUS (Brake Assist PLUS) with
Cross-Traffic Assist
General information
BAS PLUS can help you to minimize the risk of a
collision with a vehicle or a pedestrian and
reduce the effects of such a collision. If BAS
62Driving safety systems
Safety

ESP®assists the driver when pulling away on
wet or slippery roads. ESP®can also stabilize
the vehicle during braking.
ETS (Electronic Traction System)
ETS 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 transfer-
red to the wheel or wheels with traction.
Traction control remains active, even if you
deactivate ESP
®.
Important safety notes
iObserve the "Important safety notes" sec-
tion (Ypage 61).
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.
When towing the vehicle with the rear axle
raised, observe the notes on ESP
®
(Ypage 282).
If the å ESP®OFF warning lamp lights up
continuously, then ESP®is deactivated.
If the ÷ ESP®warning lamp and the å
ESP®OFF warning lamp are lit continuously,
ESP®is not available due to a malfunction.
Observe the information on warning lamps
(
Ypage 227) and display messages which may
be shown in the instrument cluster
(
Ypage 203).
iOnly use wheels with the recommended tire
sizes. Only then will ESP®function properly.
Characteristics of ESP®
General information
If the ÷ ESP warning lamp goes out before
beginning the journey, ESP®is automatically
active. If ESP
®intervenes, the
÷ESP®warning lamp
flashes in the instrument cluster.
If ESP
®intervenes:
XDo not deactivate ESP®under any circum-
stances.
XOnly depress the accelerator pedal as far as
necessary when pulling away.
XAdapt your driving style to suit the prevailing
road and weather conditions.
ECO start/stop function
The ECO start/stop function switches the
engine off automatically when the vehicle stops
moving. The engine starts automatically when
the driver wants to pull away again. ESP
®
remains in its previously selected status. Exam-
ple: if ESP®was deactivated before the engine
was switched off, ESP®remains deactivated
when the engine is switched on again.
Deactivating/activating ESP®
Important safety notes
You can select between the following states of
ESP®:
RESP®is activated.
RESP®is deactivated.
GWARNING
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.
It may be best to deactivate ESP
®in the follow-
ing situations:
Rwhen using snow chains
Rin deep snow
Ron sand or gravel
iActivate ESP®as soon as the situations
described above no longer apply. ESP®will
otherwise not be able to stabilize the vehicle 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

tions of KEYLESS-GO with those of a conven-
tional SmartKey. Unlock the vehicle by using
KEYLESS-GO, for instance, and lock it using the
&button on the SmartKey.
When locking or unlocking with KEYLESS-GO,
the distance between the SmartKey and the cor-
responding door handle must not be greater
than 3 ft (1 m).
A check which periodically establishes a radio
connection between the vehicle and the Smart-

Rwhen starting the engine
Rwhile the vehicle is in motion
XTo unlock the vehicle: touch the inner sur-
face of the door handle.

XTo unlock the trunk lid: pull the handle on
the trunk lid.
