WARNING!
•An incorrectly anchored tether strap could lead to
increased head motion and possible injury to the
child. Use only the anchor positions directly be-
hind the child seat to secure a child restraint top
tether strap.
•Do not use the cargo tie downs located on the load
floor. Improper usage of the tether can lead to a
failure of an infant or child restraint. The child
could be badly injured or killed.
Top Tether Strap Attachment
For the center seating position route the tether strap over
the seatback and headrest then attach the hook to thetop
tether anchorage located on the back of the seat behind
the gap panel. For the outboard seating positions, route
the tether strap under the headrests and attach the hook
to the top tether anchorage located on the back of the seat behind the gap panel. Please note the top tether anchor-
ages are not visible until you fold the gap panel down.
Do not use the cargo tie down hooks located on the
floor behind the seats.
Transporting Pets
Airbags deploying in the front seat could harm your pet.
An unrestrained pet will be thrown about and possibly
injured, or injure a passenger during panic braking or in
an accident. Pets should be restrained in the rear seat in
pet harnesses or pet carriers that are secured by seat belts.
ENGINE BREAK-IN RECOMMENDATIONS
A long break-in period is not required for the engine and
drivetrain (transmission and axle) in your vehicle.
Drive moderately during the first 300 miles (500 km).
After the initial 60 miles (100 km), speeds up to 50 or
55 mph (80 or 90 km/h) are desirable.

THINGS TO KNOW BEFORE STARTING YOUR VEHICLE 95

Safety Checks You Should Make Inside The
Vehicle
Seat Belts
Inspect the belt system periodically, checking for cuts,
frays, and loose parts. Damaged parts must be replaced
immediately. Do not disassemble or modify the system.
Front seat belt assemblies must be replaced after a
collision. Rear seat belt assemblies must be replaced after
a collision if they have been damaged (i.e., bent retractor,
torn webbing, etc.). If there is any question regarding belt
or retractor condition, replace the belt.
Airbag Warning Light
The light should come on and remain on for four to eight
seconds as a bulb check when the ignition switch is first
turned ON. If the light is not lit during starting, see your
authorized dealer. If the light stays on, flickers, or comes
on while driving, have the system checked by an autho-
rized dealer.
Defroster
Check operation by selecting the defrost mode and place
the blower control on high speed. You should be able to
feel the air directed against the windshield. See your
authorized dealer for service if your defroster is
inoperable.
Floor Mat Safety Information
Always use floor mats designed to fit the foot well of
your vehicle. Use only floor mats that leave the pedal
area unobstructed and that are firmly secured so that
they cannot slip out of position and interfere with the
pedals or impair safe operation of your vehicle in other
ways.
98 THINGS TO KNOW BEFORE STARTING YOUR VEHICLE

WARNING!
Pedals that cannot move freely can cause loss of
vehicle control and increase the risk of serious per-
sonal injury.
•Always make sure that floor mats are properly
attached to the floor mat fasteners.
•Never place or install floor mats or other floor
coverings in the vehicle that cannot be properly
secured to prevent them from moving and inter-
fering with the pedals or the ability to control the
vehicle.
•Never put floor mats or other floor coverings on
top of already installed floor mats. Additional
floor mats and other coverings will reduce the size
of the pedal area and interfere with the pedals.(Continued)
WARNING! (Continued)
•Check mounting of mats on a regular basis. Al-
ways properly reinstall and secure floor mats that
have been removed for cleaning.
•Always make sure that objects cannot fall into the
driver foot well while the vehicle is moving.
Objects can become trapped under the brake pedal
and accelerator pedal causing a loss of vehicle
control.
•If required, mounting posts must be properly
installed, if not equipped from the factory.
Failure to properly follow floor mat installation or
mounting can cause interference with the brake
pedal and accelerator pedal operation causing loss
of control of the vehicle.

2. Fold the rear seat completely forward.
To Raise Rear Seat
Raise the rear seatback and lock it into place. If interfer-
ence from the cargo area prevents the seatback from fully
locking, you will have difficulty returning the seat to its
proper position.
WARNING!
•Be certain that the seatback is securely locked into
position. If the seatback is not securely locked into
position the seat will not provide the proper
stability for child seats and/or passengers. An
improperly latched seat could cause serious injury.
•The cargo area in the rear of the vehicle (with the
rear seatbacks in the locked-up or folded down
position) should not be used as a play area by
children when the vehicle is in motion. They could
be seriously injured in a collision. Children
should be seated and using the proper restraint
system.

Gate Operator/Canadian Programming
Canadian radio frequency laws require transmitter sig-
nals to time-out (or quit) after several seconds of trans-
mission – which may not be long enough for HomeLink
to pick up the signal during programming. Similar to this
Canadian law, some U.S. gate operators are designed to
time-out in the same manner.
It may be helpful to unplug the device during the cycling
process to prevent possible overheating of the garage
door or gate motor.
If you are having difficulties programming a garage door
opener or a gate operator, replace “Programming
HomeLink” Step 3, with the following: 3. Continue to press and hold the HomeLink
button,
while you press and release (“cycle”), your handheld
transmitter every two seconds until HomeLink has
successfully accepted the frequency signal. The indica-
tor light will flash slowly and then rapidly when fully
trained.
If you unplugged the device for training, plug it back in
at this time.
Then proceed with Step 4 under “Programming
HomeLink,” earlier in this section.
Using HomeLink
To operate, press and release the programmed
HomeLink button. Activation will now occur for the
trained device (i.e., garage door opener, gate operator,
security system, entry door lock, home/office lighting,
etc.,). The handheld transmitter of the device may also be
used at any time.

Reprogramming A Single HomeLinkButton
To reprogram a channel that has been previously trained,
follow these steps:
1. Turn the ignition switch to the ON/RUN position.
2. Press and hold the desired HomeLink button until
the indicator light begins to flash after 20 seconds. Do not
release the button.
3. Without releasing the button, proceed with Program-
ming HomeLink Step 2 and follow all remaining steps.
Security
It is advised to erase all channels before you sell or turn
in your vehicle.
To do this, press and hold the two outside buttons for
20 seconds until the red indicator flashes. Note that all
channels will be erased. Individual channels cannot be
erased. The HomeLink
Universal Transceiver is disabled when
the Vehicle Security Alarm is active.
Troubleshooting Tips
If you are having trouble programming HomeLink, here
are some of the most common solutions:
•Replace the battery in the original transmitter.
•Press the LEARN button on the Garage Door Opener
to complete the training for a Rolling Code.
•Did you unplug the device for training, and remember
to plug it back in?
If you have any problems, or require assistance, please
call toll-free 1–800–355–3515 or, on the Internet at
