Safety belts
Seats with safety belt
The vehicle has four seats, each of which is
equipped with a safety belt.
Notes
Always make sure that safety belts are being
worn by all occupants before driving away.
Although airbags enhance safety by providing
added protection, they are not a substitute for
safety belts.
One person per safety belt
Never allow more than one person to wear
a single safety belt. Never allow infants or small
children to ride on a passenger's lap.◀
Putting on the belt
Lay the belt, without twisting, snugly
across the lap and shoulders, as close to the
body as possible. Make sure that the belt lies low
around the hips in the lap area and does not
press on the abdomen. Otherwise, the belt can
slip over the hips in the lap area in a frontal im‐
pact and injure the abdomen.
The safety belt must not lie across the neck, rub
on sharp edges, be routed over solid or breaka‐
ble objects, or be pinched.◀
Reduction of restraining effect
Avoid wearing clothing that prevents the
belt from fitting properly, and pull the shoulder
belt periodically to readjust the tension across
your lap; otherwise, the retention effect of the
safety belt may be reduced.◀
Buckling the belt
Make sure you hear the latch plate engage in the
belt buckle.
Unbuckling the belt
1.Hold the belt firmly.2.Press the red button in the belt buckle.3.Guide the belt back into its reel.Seite 54ControlsAdjusting54

Preventing an automatic engine stop
with automatic transmission
The concept
To make it possible to drive away very quickly,
such as at an intersection, the automatic engine
stop can be actively prevented.
Preventing an engine stop using the
brake pedal
The engine stop can be actively prevented
within one second after the vehicle comes to a
standstill.
▷Immediately after the vehicle comes to a
standstill, briefly press the brake pedal
forcefully.▷Then press the brake pedal with normal
