SAFETY187
(Continued)
TRANSPORTING PETS
Air Bags deploying in the front seat could harm
your pet. An unrestrained pet will be thrown
about and possibly injured, or injure a
passenger during panic braking or in a collision.
Pets should be restrained in the rear seat (if
equipped) in pet harnesses or pet carriers that
are secured by seat belts.
SAFETY CHECKS YOU SHOULD MAKE
I
NSIDE THE VEHICLE
Seat Belts
Inspect the seat belt system periodically,
checking for cuts, frays, and loose parts.
Damaged parts must be replaced immediately.
Do not disassemble or modify the system.
Front seat belt assemblies must be replaced
after a collision. Rear seat belt assemblies must
be replaced after a collision if they have been
damaged (i.e., bent retractor, torn webbing,
etc.). If there is any question regarding seat belt
or retractor condition, replace the seat belt.
Air Bag Warning Light
The Air Bag Warning Light will turn on for four
to eight seconds as a bulb check when the
ignition switch is first placed in the ON/RUN
position. If the light is either not on during
starting, stays on, or turns on while driving, have
the system inspected at an authorized dealer as
soon as possible. After the bulb check, this light
will illuminate with a single chime when a fault
with the Air Bag System has been detected. It
will stay on until the fault is removed. If the light
comes on intermittently or remains on while
driving, have an authorized dealer service the
vehicle immediately Ú page 164.
Defroster
Check operation by selecting the defrost mode
and place the blower control on high speed. You
should be able to feel the air directed against
the windshield. See an authorized dealer for
service if your defroster is inoperable.
Floor Mat Safety Information
Always use floor mats designed to fit your
vehicle. Only use a floor mat that does not
interfere with the operation of the accelerator,
brake or clutch pedals. Only use a floor mat that
is securely attached using the floor mat fasteners so it cannot slip out of position and
interfere with the accelerator, brake or clutch
pedals or impair safe operation of your vehicle
in other ways.
WARNING!
An improperly attached, damaged, folded, or
stacked floor mat, or damaged floor mat
fasteners may cause your floor mat to
interfere with the accelerator, brake, or clutch
pedals and cause a loss of vehicle control. To
prevent SERIOUS INJURY or DEATH:
ALWAYS securely attach your floor mat
using the floor mat fasteners. DO NOT
install your floor mat upside down or turn
your floor mat over. Lightly pull to confirm
mat is secured using the floor mat
fasteners on a regular basis.
ALWAYS REMOVE THE EXISTING FLOOR
MAT FROM THE VEHICLE before
installing any other floor mat. NEVER install
or stack an additional floor mat on top of an
existing floor mat.
