Never place a rear-facing child restraint in
front of an air bag. A deploying passenger
front air bag can cause death or serious injury
to a child 12 years or younger, including a
child in a rear-facing child restraint.
WARNING!WARNING!
Improper installation can lead to failure of an
infant or child restraint. It could come loose in
a collision. The child could be badly injured or
killed. Follow the child restraint manufac-
turer’s directions exactly when installing an
infant or child restraint.
After a child restraint is installed in the
vehicle, do not move the vehicle seat forward
or rearward because it can loosen the child
restraint attachments. Remove the child
restraint before adjusting the vehicle seat
position. When the vehicle seat has been
adjusted, reinstall the child restraint.
When your child restraint is not in use, secure
it in the vehicle with the seat belt or LATCH
anchorages, or remove it from the vehicle. Do
not leave it loose in the vehicle. In a sudden
stop or accident, it could strike the occupants
or seatbacks and cause serious personal
injury.

Use only the manufacturer recommended
brake fluid Úpage 452. Using the wrong type
of brake fluid can severely damage your brake
system and/or impair its performance. The
proper type of brake fluid for your vehicle is
also identified on the original factory installed
hydraulic master cylinder reservoir.
To avoid contamination from foreign matter or
moisture, use only new brake fluid or fluid that
has been in a tightly closed container. Keep
the master cylinder reservoir cap secured at
all times. Brake fluid in an open container
absorbs moisture from the air resulting in a
lower boiling point. This may cause it to boil
unexpectedly during hard or prolonged
braking, resulting in sudden brake failure. This
could result in a collision.
Overfilling the brake fluid reservoir can result
in spilling brake fluid on hot engine parts,
causing the brake fluid to catch fire. Brake
fluid can also damage painted and vinyl
surfaces, care should be taken to avoid its
contact with these surfaces.

If operating the vehicle without carpet in place
the floor may become hot, and there is a risk
of burns.
An improperly attached, damaged, folded, or
damaged grommets may cause your carpet 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 carpet using the grommets.
ALWAYS make sure objects cannot fall or slide
into the driver’s side floor area when the
vehicle is moving. Objects can become
trapped under accelerator, brake, or clutch
pedals and could cause a loss of vehicle
control.
