cause child restraint systems and
their components to become very
hot. Persons may sustain burn
injuries when touching the hot
components. There is a risk of

General information
Safety information
WARNING
Active front-seat passenger air-
bags can injure a child in a child
restraint system when the airbags
are activated. There is a risk of
injury. Make sure that the
front-seat passenger airbags are
deactivated and that the PAS-
SENGER AIRBAG OFF indicator
light lights up.
The safety bel t cannot be fas-
tened correctly on children shorter
than 5 ft, 150 cm without suitable
additional child restraint systems.
The efficacy of safety gear, includ-
ing safety belts, can be limited or
lost when safety belts are fas-
tened incorrectly. An incorrectly
fastened safety belt can cause
additional injuries, for instance in

systems
General information

1163-1. CONTROLS
Before installing a child restraint
system in the front passenger
seat, make sure that the front,
knee and side airbags on the
front passenger side are deacti-
vated.

senger airbags automatically,
refer to page 175.
After installing a child restraint
system, move the front passen-
ger seat as far back as it will go
and, if possible, bring it up to
medium height. This seat posi-
tion and height ensure the best
possible position for the belt and
offers optimal protection in the
event of an accident.
If the upper anchor of the safety
belt is located in front of the belt
guide of the child seat, move the
front passenger seat carefully

ccident or brak-
ing and evasive maneuvers.
There is a risk o f injuries or dan-
ger to life. Do not use child
restraint systems which have
been damaged or e xposed to an
accident. If a child restraint sys-
tem and its fastening system has
been damaged or e xposed to an
accident, have these systems
checked and replaced by your
Toyota dealer.
