significant reduction in
pressure occurs in one or
more of the vehicle’s tires
by illuminating the low tire
pressure warning light on
the instrument cluster.
The warning light will remain on until the tire pressure is
corrected. The proper tire pressures for your vehicle are
listed on the Tire and Loading Information label located
on the driver side center pillar (B pillar). See Loading
the Vehicle
on page 5‑31.
You may notice during cooler conditions that the low tire

an early indicator that your tire pressures are getting
low and the tires need to be inflated to the proper
pressure.

Head Restraints
The front seats have adjustable head restraints in the
outboard seating positions.
{WARNING:
With head restraints that are not installed and
adjusted properly, there is a greater chance that
occupants will suffer a neck/spinal injury in a
crash. Do not drive until the head restraints for all
occupants are installed and adjusted properly.
Adjust the head restraint so that the top of the restraint
is at the same height as the top of the occupant's head.
This position reduces the chance of a neck injury in
a crash.

{WARNING:
Sitting in a reclined position when your vehicle is
in motion can be dangerous. Even if you buckle
up, your safety belts cannot do their job when you
are reclined like this.(Continued)
WARNING: (Continued)
The shoulder belt cannot do its job. In a crash,
you could go into it, receiving neck or other
injuries.
The lap belt cannot do its job either. In a crash the
belt could go up over your abdomen. The belt
forces would be there, not at your pelvic bones.
This could cause serious internal injuries.
For proper protection when the vehicle is in
motion, have the seatback upright. Then sit well
back in the seat and wear your safety belt
properly.
Do not have a seatback reclined if your vehicle is
moving.
