interior or on the infant or child restraint.
Special seat belt retractor
GWARNING
If you release the seat belt when driving, the
special seat belt retractor is deactivated.
The released seat belt cannot be engaged
again while driving, because the inertia reel
pulls in the seat belt a small distance. The
child restraint system is no longer properly
secured. There is an increased risk of serious
injury or even fatal injury.
Always keep the seat belt of the activated
special seat belt retractor engaged when
driving.
All seat belts except the driver's seat belt are
equipped with a special seat belt retractor.
When activated, the special seat belt
retractor ensures that the seat belt will not
slacken once the child restraint system has
been secured.

passenger seat
GWARNING
If the front-passenger front air bag is not
deactivated:
Ra child secured in a child restraint system
on the front-passenger seat could be
seriously or even fatally injured by the front-
passenger air bag deploying. This is
especially a risk if the child is in the
immediate vicinity of the front-passenger
air bag when it deploys.
Rnever secure a child on the front-passenger
seat in a rearward-facing child restraint
system. Only secure a rearward-facing
child restraint system on a suitable rear
seat.
Rand you secure a forward-facing child
restraint system to the front-passenger
seat, you must move the front-passenger
seat as far back as possible. When doing
so, ensure that the shoulder belt strap from
the belt outlet on the vehicle is routed
towards the front to the shoulder belt guide
on the child restraint system. Set the belt
height adjustment so that the belt strap is
routed towards the front along the bottom.
The front-passenger air bag is not
deactivated:

LATCH-type (ISOFIX) child seat anchors
in the rear
GWARNING
LATCH-type (ISOFIX) child restraint systems
do not offer sufficient protective effect for
children whose weight is greater than 48 lbs
(22 kg) who are secured using the safety belt
integrated in the child restraint system. In the
event of an accident, a child might not be
restrained correctly. This poses an increased
risk of injury or even fatal injury.
If the child weighs more than 48 lbs (22 kg),
only use LATCH-type (ISOFIX) child restraint
systems with which the child is also secured
with the vehicle seat belt. Also secure the
child restraint system with the Top Tether
belt, if available.
When installing a child restraint system, be
sure to observe the manufacturer's
installation instructions and the instructions
for correct use of the child restraint system.
!When installing the LATCH-type (ISOFIX)
child restraint system, make sure that the
seat belt for the center seat does not get
trapped. Otherwise, the seat belt could be
damaged.
XInstall the LATCH-type (ISOFIX) child
restraint system. Comply with the child
restrain system manufacturer's
instructions when installing the LATCH-
type (ISOFIX) child restraint system.

ringsfor two LATCH-type (ISOFIX) child
restraint systems are installed on the left and
right of the rear seats.
Non-LATCH-type (ISOFIX) child seats may
also be used and can be installed using the

seat according to the manufacturer's
instructions.
Top Tether
Important safety notes
GWARNING
Always engage the rearseat backrests in an
upright position before installing the Top
Tether belt. Push and pull the rear seat
backrests to check whether they are engaged
correctly. If the seat backrest is not locked
properly, the seat backrest could fold. The
child seat would no longer be supported
properly or positioned to provide its intended
benefit.That could cause serious or even fatal
injuries.
Example: Top Tether belt with one belt strap
Top Tether provides an additional connection
between the LATCH-type (ISOFIX) child
restraint system secured with ISOFIX and the
rear seat. This helps reduce the risk of injury
even further. If the child restraint system is
installed with Top Tether, this should always
be used.
The Top Tether anchorage points are installed
in the rear compartment behind the outer
head restraints on the parcel shelf.
There is also another Top Tether anchorage
point behind the central rear seat.

If the driver's seat belt is fastened,
COLLISION PREVENTION ASSIST PLUS can
brake automatically withinaspeed range of
between 4 mph (7 km/h) and 124 mph
(200 km/h).
COLLISION PREVENTION ASSISTPLUS can
also react to stationary obstacles with
automatic braking within a speed range of
between 4 mph (7 km/h) and 19 mph
(30 km/h).
In particular, the detection of obstacles can
be impaired if:
Rdirt on the sensors or anything else
covering the sensors
Rsnow or heavy rain
Rinterference by other radarsources
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
relative to the center of your vehicle
Following damage to the front end of the
vehicle, have the configuration and operation
of the radar sensor checked at a qualified
specialist workshop. This also applies to
collisions 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"
section (Ypage 61).
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)
iObserve the "Important safety notes"
section (Ypage 61).
ETS/4ETS traction control is part of ESP®.
ETS brakes the drive wheels individually 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 transferred to
the wheel or wheels with traction.
ETS remains active when you deactivate
ESP®.
Important safety notes
GWARNING
If ESP®is malfunctioning, ESP®is unable to
stabilize the vehicle. Additionally, further
driving safety systems are deactivated. This
increases the risk of skidding and an accident.
Drive on carefully. Have ESP®checked at a
qualified specialist workshop.
