Upper backrest
Principle
The upper backrest supports the back in the
shoulder region. A correct setting leads to a re‐
laxed seat position and reduces strain on the
shoulder muscles.
General information
If the driver's door is opened when the drive-
ready state is switched off, the upper backrest
moves into the basic setting.
Adjusting
▷ Press the front section of the button:
The upper backrest is inclined forward.
▷ Press the rear section of the button:
The upper backrest is inclined backward.
Safety belts
General information
The vehicle is fitted with four or five safety belts
to ensure occupants' safety. However, they can
only unfold their protective effect when adjusted
correctly.
Always make sure that safety belts are being
worn by the occupants before driving off. The
airbags supplement the safety belts as an addi‐
tional safety device. The airbags do not replace
safety belts.
Seats, mirrors and steering wheel
Online Edition for Part no. 01405A37B39 - VI/21
All belt fastening points are designed to achieve
the best possible protective effect of the safety
belts with proper use of the safety belts and cor‐
rect seat setting. Notes on sitting safely, refer to
page 114.
The two outer safety belt buckles of the rear
seats are intended for the persons sitting on the
left and right.
The center safety belt buckle of the rear seats is
intended for the person sitting in the middle.
Safety information
Warning
Use of a safety belt to buckle more than one
person will potentially defeat the ability of the
safety belt to serve its protective function.
There is a risk of injury or danger to life. Do not
allow more than one person to wear a single
safety belt. Infants and children are not allowed
on an occupant's lap, but must be transported
and secured in designated child restraint sys‐
tems.
Warning
The protective effect of safety gear, including
safety belts, can be limited or lost when safety
belts are fastened incorrectly. An incorrectly
fastened safety belt can cause additional inju‐
ries, for instance in the event of an accident,
braking or evasive maneuvers. There is a risk of
injury or danger to life. Make sure that all occu‐
pants are wearing safety belts correctly.
Warning
With a rear backrest that is not locked, the pro‐
tective effect of the middle safety belt is not
guaranteed. There is a risk of injury or danger
to life. If you are using the middle safety belt,
lock the wider rear seat backrest.
