HomeLink® Universal Transceiver
The HomeLink ® Universal Transceiver can be pr ogrammed to operate up to three
remote controlled devices around your hom e, such as garage doors, lighting, or
home security systems.
Refer to the safety information that came wi th your garage door opener to test that
the safety features are functioning prope rly. If you do not have the safety
information, contact the manufacturer.
Before programming HomeLink, make sure th at people and objects are out of the
way of the garage or gate to prevent potential injury or damage.

■Important Safety Precautions
1HomeLink ® Universal Transceiver

Before Driving
Driving Preparation
Check the following items before you start driving.
• Make sure there are no obstructions on the windows, door mirrors, exterior
lights, or other parts of the vehicle.
u Remove any frost, snow, or ice.
u Remove any snow on the roof, as this can slip down and obstruct your field of
vision while driving. If frozen solid , remove ice once it has softened.
u When removing ice from around the wheels, be sure not to damage the wheel
or wheel components.
• Make sure the hood is securely closed.
u If the hood opens while driving, your front view will be blocked.
• Make sure the tires are in good condition.
u Check air pressures, and check for damage and excessive wear.
2Checking and Maintaining Tires P. 516
•Make sure the tailgate is fully closed when it is not being used as an extended
pickup bed.
• Make sure the trunk is secu rely closed and locked.
• Make sure there are no people or ob jects behind or around the vehicle.
u There are blind spots from the inside.
■Exterior Checks1Exterior Checks
NOTICE
When doors are frozen s hut, use warm water around
the door edges to melt any ice. Do not try to force
them open, as this can damage the rubber trim
around the doors. When done, wipe dry to avoid
further freezing.
Do not pour warm water into the key cylinder.
You will be unable to insert the key if the water
freezes in the hole.
Heat from the engine and exhaust can ignite
flammable material s left under the hood, causing a
fire. If you’ve parked y our vehicle for an extended
period, inspect and remove any debris that may have
collected, such as dried grass and leaves that have
fallen or have been carried in for use as a nest by a
small animal. Also check under the hood for leftover
flammable materials after you or someone else has
performed maintenance on your vehicle.

uuBefore Driving uCarrying Cargo
Driving
Carrying Cargo
Your vehicle can carry a large amount of cargo in the pickup bed.
However, the pickup bed is not intended for carrying passengers.
People who ride in the pickup bed can be ve ry seriously injured or killed in a crash.
• When loading and unloading cargo, make sure all passengers or any objects are
clear of the tailgate before opening or closing it. The tailgate should be closed
securely before driving when it is not used as the extended pickup bed.
• The maximum allowable loading weight for the trunk is 300 lbs (136 kg).
Do not exceed this weight limi t, or you may damage the trunk.
• The maximum allowable loading weight on the pickup bed is 1,100 lbs (500 kg).
Do not exceed the load limit.
2 Maximum Load Limit P. 367
•Distribute cargo evenly on the pickup bed. Place the heaviest items on the bottom
and as far forward as possible of the rear axle. Tie down and secure all items that
could be thrown out of the vehicle during a crash or sudden stop.
• If you stack items higher than the bed si des, tailgate, or back window, secure
them with a net or cover.
This will reduce the risk of items being thrown out of the pickup bed during a
crash or sudden stop.
• When the tailgate is dropped open, it can be used as an extended pickup bed.
The maximum allowable weight on the tailgate while driving is 300 lbs (136 kg).
Exceeding this limit c ould damage the tailgate.
• Carrying heavy cargo in the pickup bed will raise your vehicle’s center of gravity.
This can affect handling and performance. Drive more slowly and cautiously, and
allow extra time and distance for braking.
■Carrying Cargo in the Pickup Bed1 Carrying Cargo
3WARNING
Allowing passengers to ride in the pickup
bed or on the tailgate can result in death or
serious injury in a crash.
Make sure all passengers ride in a seat and
wear a seat belt properly.
3WARNING
Never let passengers ride in the pickup bed,
in the trunk space, or on the bed rails. This
could cause very serious injuries or death.
No one should ride in any position on your
vehicle that is not eq uipped with seats and
seat belts.
Exceeding load limits or improperly loading
cargo on the vehicle can cause a crash in
which you can be seriously injured or killed.
Load the cargo carefully before starting to
drive.
