The TPMS warming light
alerts you to a significant
loss in pressure of one of
the vehicles tires.
If the warning light comes on, stop as soon as possible
and inflate the tires to the recommended pressure
shown on the tire loading information label. See
Loading the Vehicle
on page 5‑18. The warning light
will remain on until the tire pressure is corrected.
During cooler conditions, the low tire pressure warning
light may appear when the vehicle is first started and
then turn off. This may be an early indicator that the
tire pressures are getting low and the tires need to be
inflated to the proper pressure.
The TPMS does not replace normal monthly tire
maintenance. It is the driver ’s responsibility to maintain
correct tire pressures.
See Tire Pressure Monitor System
on page 6‑65and

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.

Reclining Seatbacks
{WARNING:
Sitting in a reclined position when the vehicle is in
motion can be dangerous. Even when buckled up,
the safety belts cannot do their job when reclined
like this.
The shoulder belt cannot do its job because it will
not be against your body. Instead, it will be in front
of you. 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 the safety belt properly.
Do not have the seatback reclined if your vehicle is
moving.

your safety belt, and check that your passenger(s)
are restrained properly too.

It is extremely dangerous to ride in a cargo
area, inside or outside of a vehicle. In a collision,
people riding in these areas are more likely to
be seriously injured or killed. Do not allow people
to ride in any area of your vehicle that is not
equipped with seats and safety belts. Be sure
everyone in the vehicle is in a seat and using a
safety belt properly.
This vehicle has indicators as a reminder to buckle the
safety belts. See Safety Belt Reminders

Q: What is wrong with this?
A:The shoulder belt is too loose. It will not give as
much protection this way.
{WARNING:
You can be seriously hurt if the shoulder belt is
too loose. In a crash, you would move forward too
much, which could increase injury. The shoulder
belt should fit snugly against your body.
