Adjust the head restraint so that it supports
the back of the head at eye level.
R The distance from the pedals should be
such that you can depress them fully.
Observe also the safety notes in the section
on "Air bags" (Y page 47)and "Children in the
vehicle" (Y page 51).
If you swap over the head restraints for the
front and rear seats, you will not be able to
adjust the height and angle of the head
restraints to the correct position.
Use the head restraint pad to adjust the head
restraint so that it is as close as possible to
the back of your head.
Before the journey, make sure the head
restraints have been correctly set for each of the vehicle's passengers (Y page 86).Driver's and co-driver's seat

Useful information
This Operator's Manual describes all models
as well as standard and optional equipment of your vehicle that were available at the time of going to print. Country-specific variations are
possible. Note that your vehicle may not be
equipped with all of the described functions.
This also applies to systems and functions
relevant to safety.
Read the information on qualified specialist
workshops (Y page 25). Important safety notes
G
WARNING
If you are driving and reach through the steer- ing wheel to operate the adjustment knob,
you could lose control of the vehicle. There is
a risk of an accident and injury.
Only operate the adjustment knobs when the vehicle is stationary. Do not reach through the
steering wheel when driving. G
WARNING
If you operate information systems and com-
munication equipment integrated in the vehi- cle while driving, you will be distracted from
traffic conditions. You could also lose control of the vehicle. There is a risk of an accident.
Only operate the equipment when the traffic
situation permits. If you are not sure that this
is possible, park the vehicle paying attention
to traffic conditions and operate the equip-
ment when the vehicle is stationary. G
WARNING
If the instrument cluster has failed or mal-
functioned, you may not recognize function
restrictions in systems relevant to safety. The operating safety of your vehicle may be
impaired. There is a risk of an accident.
Drive on carefully. Have the vehicle checked
at a qualified specialist workshop immedi-
ately. You must observe the legal requirements for
the country in which you are currently driving
when operating the on-board computer.
The on-board computer display only shows
messages and warnings from certain sys-
tems. You should therefore make sure your
vehicle is operating safely at all times. If the
operating safety of your vehicle is impaired,
stop the vehicle as soon as possible, paying
attention to road and traffic conditions. Then consult a qualified specialist workshop. Instrument cluster
