Head restraints are designed to
support the head, not the back of the
neck. The restraint must be positioned
correctly to restrain rearward
movement of the head in a collision. An
incorrectly adjusted head restraint
increases the risk of death or serious
injury in the event of a collision.

!

WARNING:

Adjust the head restraint so that the
top of the head restraint is above the
centre line of the head. An incorrectly
adjusted head restraint increases the
risk of death or serious injury in the
event of a collision.

A heater will maintain a pre-set
