Safety belts
Number of safety belts
The vehicle is fitted with five safety belts to en‐
sure occupant safety. However, they can only
offer protection when adjusted correctly.
The two outer safety belt buckles, integrated
into the rear seat, are for passengers sitting on
the left and right.
The center safety belt buckle of the rear seat is
solely intended for the person sitting in the
middle.
General information
Always make sure that safety belts are being
worn by all occupants before driving off.
For the occupants' safety the belt locking
mechanism triggers early. Slowly guide the
safety belt out of the holder when applying it.
If needed, disengage the safety belt in the rear
from the belt buckle on the side.
Although airbags enhance safety by providing
added protection, they are not a substitute for
safety belts.
Information
WARNING
If the safety belt is used by more than
one person, the protective effect of the safety
belt cannot be ensured anymore. There is risk
of injuries or danger to life. Do not allow more
than one person to wear a single safety belt. In‐
fants and children are not allowed in an occu‐
pant's lap, but must be transported and respec‐
tively secured in designated child restraint
systems.◀
WARNING
The protective effect of the safety belts
can be limited or lost when safety belts are fas‐
tened incorrectly. An incorrectly fastened safety
belt can cause additional injuries, for example
in the event of an accident or during braking
and evasive maneuvers. There is risk of injuries
or danger to life. Make sure that all occupants
are wearing safety belts correctly.◀
WARNING
With a rear backrest that is not locked,
the protective function of the middle safety belt
is not guaranteed. There is risk of injuries or
danger to life. If you are using the middle safety
belt, lock the wider rear backrest.◀
Correct use of safety belts
▷Wear the safety belt twist-free and as tight
to your body as possible over your lap and
shoulders.
▷Wear the safety belt deep on your hips over
your lap. The safety belt may not press on
your stomach.
▷Do not wear the safety belt on your throat,
rub it on sharp edges, guide it or jam it in
across hard or fragile objects.
▷Avoid thick clothing.▷Re-tighten the safety belt frequently up‐
ward around your upper body.

Switching off
Turn wheel for air quantity to the
left until the control switches off.
Temperature
Turn the ring to set the desired
temperature.
Cooling function
The air in the car's interior will be cooled and
dehumidified and, depending on the tempera‐
ture setting, warmed again.
The car's interior can only be cooled with the
engine running.
Press button.
Air conditioning is switched on or off.
Depending on the weather, the windshield may
fog up briefly when the engine is started.
The air conditioner produces condensation wa‐
ter, refer to page 164, that will exit from below
the car.
Recirculated-air mode
You may respond to unpleasant odors or pollu‐
tants in the immediate environment by tempo‐
rarily suspending the supply of outside air. The
system then recirculates the air currently within
the vehicle.
Press button repeatedly to select an
operating mode:
▷LED off: outside air flows in continuously.▷LED on, recirculated-air mode: the supply
of outside air into the vehicle is perma‐
nently blocked.
To prevent window condensation, recirculated
air mode switches off automatically after a cer‐
tain amount of time, depending on the external
temperature.
With constant recirculated-air mode, the air
quality in the car's interior deteriorates and the
fogging of the windows increases.
If the windows fog over, switch off recirculated-
air mode and increase the air flow, if needed.
Air flow, manual
Turn the ring to set the desired
air volume.
The higher the rate, the more ef‐
fective the heating or cooling will
be.
The air flow from the air conditioner may be re‐
duced automatically to save battery power.

sired program or the desired in‐
termediate setting.
