Starting at approximately 43 mph/70 km/h, the
system is active and can display a recommen‐
dation to take a break.
Break recommendation
If the driver becomes increasingly less alert or
fatigued, a message is displayed in the Control
Display with the recommendation to take a
break.
A recommendation to take a break is displayed
only once during an uninterrupted trip.
After a break, another recommendation to take
a break cannot be displayed until after approxi‐
mately 45 minutes.
System limits
The function may be limited in the following
situations, for instance, and will either output
an incorrect warning or no warning at all:▷When the clock is set incorrectly.▷When the vehicle speed is mainly below
about 43 mph/70 km/h.▷With a sporty driving style, such as during
rapid acceleration or when cornering fast.▷In active driving situations, such as when
changing lanes frequently.▷When the road surface is poor.▷In the event of strong side winds.
PreCrash
The concept With this system critical driving situations that
might result in an accident can be detected
above a speed of approx. 20 mph/30 km/h. In these situations, preventive measures are au‐
tomatically taken to minimize the risk of an ac‐
cident as much as possible.
Critical driving situations may include:
▷Emergency stop.▷Severe understeering.▷Severe oversteering.If the vehicle includes the front-end collision
warning or front-end collision warning with
braking feature, impending collisions with vehi‐
cles driving ahead or stopped in front of you
can also be detected within the system's
range.
Note Personal responsibility
The system cannot possibly serve as a
substitute for the driver's personal judgment of
the traffic situation. The system may not al‐
ways detect critical situations reliably and in a
timely manner. Adapt speed to traffic situation
and drive alertly; otherwise, a risk to safety may
result.◀
Function
After the safety belt is buckled, the front belts
are automatically pretensioned once after the
vehicle is driven is away.
In critical driving situations, the following indi‐
vidual functions become active as needed:▷The front belts are automatically preten‐
sioned.▷Automatic closing of the windows.▷Automatic closing of the glass sunroof.▷For vehicles equipped with power backrest
adjustment: automatic positioning of the
backrest for the front passenger seat.
After a critical driving situation without an acci‐
dent, the front belts are loosened again. All
other systems can be restored to the desired
setting.
If the belt tension does not loosen automati‐
cally, stop the vehicle and unbuckle the belt
using the red button in the buckle. Fasten the
belt before continuing on your trip.
PostCrash
In the event of an accident, the system can
bring the car to a halt automatically without in‐
tervention by the driver in certain situations.

middle section is folded down. Otherwise, in‐
jury or damage may result.◀
Ensuring the stability of the child seat
When installing child restraint systems,
make sure that the child seat is securely fas‐
tened to the backrest of the seat. Angle and
headrest of the backrest might need to be ad‐
justed or possibly be removed. Make sure that
all backrests are securely locked. Otherwise
the stability of the child seat can be affected,
and there is an increased risk of injury because
of unexpected movement of the rear seat
backrest.◀
Opening Move the front seats to an upright posi‐
tion
Before folding down the rear backrests, ensure
that the front seats are moved forward slightly
and are in an upright position. Otherwise, the
head restraint and screen could be damaged.◀1.Unlock the belt lock of the center safety

area to release the rear seat backrest.5.The unlocked rear seat backrest moves
forward slightly.6.Fold backrest forward.
Closing
1.Return the rear seat backrest to the upright
seating position and engage it.
Ensure that the lock is securely en‐
gaged
Make sure that the lock engages properly
when folding back, otherwise transported
cargo could enter the car's interior during
braking or evasive maneuvers and endan‐
ger the vehicle's occupants.◀2.Release the belt tongue from the fixture on
the rear window shelf.3.Insert the belt tongue in the belt lock of the
center safety belt. Make sure you hear the

Load
The maximum load is the sum of the weight of
the occupants and the cargo.
The greater the weight of the occupants, the
less cargo that can be transported.
Stowing cargo
▷Cover sharp edges and corners on the
cargo.▷Heavy cargo: stow as far forward as possi‐
ble, directly behind and at the bottom of
the rear passenger seat backrests.▷Very heavy cargo: when the rear seat is not
occupied, secure each of the outer safety
belts in the opposite buckle.▷If necessary, fold down the rear backrests
to stow cargo.▷Do not stack cargo above the top edge of
the backrests.Securing cargo

▷Smaller and lighter items: secure with re‐
taining straps or with a cargo net or draw
straps.▷Larger and heavy objects: secure with
cargo straps.
Cargo straps, cargo netting, retaining straps or
draw straps on the lashing eyes in the cargo
area.
