Tailgate
Tailgate (H3T)
{WARNING
It is extremely dangerous to ride
on the tailgate, even when the
vehicle is operated at low speeds.
People riding on the tailgate
can easily lose their balance
and fall in response to vehicle
maneuvers. Falling from a moving
vehicle may result in serious
injuries or death. Do not allow
people to ride on the tailgate.
Be sure everyone in your vehicle
is in a seat and using a safety
belt properly.
Open the tailgate by pulling up on
the outside handle while pulling the
tailgate down.
When putting the tailgate up, be
sure it latches securely.Removing the Tailgate
To remove the tailgate:
1. Open the tailgate fully and
remove the retainer clip from the
driver's side hinge.
It is recommended that the
retainer clip be stored in a safe
place, like the glove box.

the bolt, slide the bracket off of
the bolt.
3. With the tailgate partially down, lift up on the passenger's side

Tailgate Partially Down
2. Remove the retaining cable from the passenger side of the pickup
box by pulling the clip away from
the bolt head while pushing the
cable bracket forward.
When the larger part of the hole
on the bracket is over the bolt,
slide the bracket off of the bolt. 3. Slide the lower end fitting onto
the front bolt. The tailgate will
now stay in the partially opened
position.
4. Repeat Steps 2 and 3 for the driver side.
When closing the tailgate the
bracket cannot be in the partially
opened position. It must be
anchored on the rear bolt using
the top position on the bracket.
Swing-gate (H3)
To lock or unlock the swing‐gate,
use the power door lock switch or
the Remote Keyless Entry (RKE)
transmitter.
{WARNING
Make sure the swing‐gate is
completely closed. Driving with
the swing‐gate open could injure
pedestrians or damage the
vehicle.

Seats and Restraints 3-11
{WARNING
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
your vehicle is in a seat and using
a safety belt properly.
{WARNING
People riding on the tailgate
(if equipped) can easily lose their
balance and fall even when the
vehicle is operated at low speeds.
Falling from a moving vehicle may
result in serious injuries or death.
This vehicle has indicators as a
reminder to buckle the safety belts.
See Safety Belt Reminders
on
page 5‑9for additional information. In most states and in all Canadian
provinces, the law requires wearing
safety belts. Here is why:
You never know if you will be in a
crash. If you do have a crash,
you do not know if it will be a
serious one.
A few crashes are mild, and some
crashes can be so serious that even
buckled up, a person would not
survive. But most crashes are in
between. In many of them, people
who buckle up can survive and
sometimes walk away. Without
safety belts they could have been
badly hurt or killed.
After more than 40 years of safety
belts in vehicles, the facts are clear.
In most crashes buckling up does
matter ... a lot!
