●Always install the floor mat securely
using the retaining hooks (clips) pro-
vided.
●Do not use two or more floor mats on
top of each other.
●Do not place the floor mat bottom-

●Do not adjust the position of the
driver’s seat while driving.
Doing so could cause the driver to lose
control of the vehicle.
●Do not place a cushion between the
driver or passenger and the seatback.
A cushion may prevent correct pos-
ture from being achieved, and reduce
the effectiveness of the seat belt and
head restraint.
●Do not place anything under the front
seats.
Objects placed under the front seats
may become jammed in the seat
tracks and stop the seat from locking
in place. This may lead to an accident
and the adjustment mechanism may
also be damaged.
●Always observe the legal speed limit
when driving on public roads.
●When driving over long distances,
take regular breaks before you start to
feel tired.
Also, if you feel tired or sleepy while
driving, do not force yourself to con-
tinue driving and take a break immedi-
ately.

■Emergency locking retractor (ELR)
The retractor will lock the belt during a sud-

you can move around fully.
■Automatic locking retractor (ALR)
When a passenger’s shoulder belt is com-
pletely extended and then retracted even
slightly, the belt is locked in that position
and cannot be extended. This feature is
used to hold a child restraint system (CRS)
firmly. To free the belt again, fully retract the
belt and then pull the belt out once more.
The front seats are equipped with
guides to pass the seat belt. When
using the seat belt, make sure to pass
the seat belt through the guide.
When getting into or out of a rear seat,
release the seat belt from the guide.
WARNING
●Do not wear the seat belt extender if
you can fasten the seat belt without the
extender.
●Do not use the seat belt extender
when installing a child restraint system
because the belt will not securely hold
the child restraint system, increasing
the risk of death or serious injury in the
event of an accident.
●The personalized extender may not be
safe on another vehicle, when used by
another person, or at a different seat-
ing position other than the one origi-
nally intended.
