To prevent the Occupant
Classification System from mal-
functioning:
Do not hang onto the front pas-
senger’s seatback.
WARNING
Never allow passengers to sit
on top of the folded down

seating position and no seat
belts are available for use.
This could result in serious
injury or death in case of an
accident or sudden stop.
Objects carried on the folded
down seatback should not
extend higher than the top of
the front seatbacks. This
could allow cargo to slide for-
ward and cause injury or dam-
age during sudden stops.
WARNING

objects in the seatback pockets.
In an accident they could come
loose from the pocket and
injure occupants.

Make sure the engine is off, the
shift lever is in P (Park), and the
parking brake is securely applied
whenever loading or unloading
cargo. Failure to take these steps
may allow the vehicle to move if
the shift lever is inadvertently

have adjustable head restraints. The
head restraints provide comfort for
passengers, but more importantly

cargo through the rear pas-
senger seats to prevent dam-
age to the vehicle interior.
When cargo is loaded through
the rear passenger seats,
ensure the cargo is properly
secured to prevent it from
moving while driving.
Unsecured cargo in the pas-
senger compartment can
cause damage to the vehicle
or injury to it’s occupants.

head restraints for all passen-
gers BEFORE starting the
vehicle.
