Features
HomeLink® Universal TransceiverThe HomeLink ® Universal Transceiver can be programmed to operate up to three
remote controlled devices around your home, such as garage doors, lighting, or
home security systems.
Refer to the safety information that came with your garage door opener to test that
the safety features are functioning properly. If you do not have the safety
information, contact the manufacturer.
Before programming HomeLink, make sure that people and objects are out of the
way of the garage or gate to prevent potential injury or damage.
When programming a garage door opener, park just outside the garage door’s
path.Training HomeLink
If you have not trained any of the buttons in
HomeLink before, you should erase any
previously learned codes. To do this:
• Press and hold the two outside buttons for
about 20 seconds, until the red indicator
blinks. Release the buttons, and proceed to
step 1.
• If you are training the second or third
button, go directly to step 1.

Before DrivingDriving PreparationCheck 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 pressure, check for damage and excessive wear.
2 Checking and Maintaining Tires P. 421
•Make sure there are no people or objects behind or around the vehicle.

Exterior Checks
1Exterior ChecksNOTICEWhen doors are frozen shut, 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 materials left under the hood, causing a
fire. If you’ve parked your 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.

■Trailer brakes
Recommended for any trailer with a total weight of 1,000 lbs (450 kg) or more:
There are two common types of trailer brakes: surge and electric. Surge brakes are
common for boat trailers, since the brakes will get wet.
If you choose electric brakes, be sure they are electronically actuated. Do not
attempt to attach trailer brakes to your vehicle’s hydraulic system, as it will lower
braking effectiveness and create a potential hazard.
The 4-pin gray connector installed in your vehicle has all of the circuits required to
install most electric trailer brake controllers.
Have a qualified mechanic install your trailer
brake controller following the trailer brake
controller manufacturer’s instructions. Failure
to properly install the trailer brake controller
may increase the distance it takes for you to
stop your vehicle when towing a trailer.

The 4-pin gray connector is located under the

uuTowing a Trailer uTrailer Stability Assist
*
Driving
Trailer Stability Assist
*
Helps to stabilize the vehicle and trailer when the trailer severely sways.■How trailer stability assist works
When the vehicle and trailer become unstable while driving, trailer stability assist
determines the cause. If the trailer oscillation is detected as the cause, and the
swaying increases, the system applies the brakes or controls engine output to reduce
vehicle speed.
Both the vehicle and trailer brake lights come on automatically if you brake to
reduce vehicle speed.
1 Trailer Stability Assist
*
Trailer stability assist is not a function that prevents
the vehicle and trai ler from swaying. Avoid high
speeds, abrupt steering, improper trailer load, and
sudden braking to keep the trailer from swaying.
When swayed too severely, the system becomes
ineffective, and you may loose control of your
vehicle, causing the trailer to roll over or get
damaged. 2 Driving Safely with a Trailer P. 320
Trailer towing sway is caused by:•Crosswinds•Improper towbar down load•Excessive Speed
The VSA ® system indicator blinks during the trailer
stability assist operation.

3. Press the ENGINE START/STOP button
without depressing the accelerator pedal.
The engine will crank until it starts.
1 Starting the Engine
Keep your foot firmly on the brake pedal when
starting the engine.
The engine is harder to start in cold weather and in
thinner air found at altitudes above 8,000 feet (2,400
meters).When starting the engine in cold weather, turn off all
electrical accessories such as the lights, climate control
system, and rear defogger in order to reduce battery drain.If you live in a region where winter is extremely cold,
an engine block heater will improve starting and
warming of the engine. If temperatures consistently
below -22°F (-30°C) are expected, the coolant
mixture should be changed to a higher concentration
to prevent freezing. Consult a dealer for details.
If the exhaust system sounds abnormal or you can
smell exhaust gas inside the vehicle, have your vehicle
checked by a dealer. There may be a problem with
the engine or exhaust system.
Bring the keyless access remote close to the ENGINE
START/STOP button if the battery in the keyless
access remote is weak. 2 If the Keyless Access Remote Battery is
Weak P. 463
The engine may not start if the keyless access remote
is subjected to strong radio waves.
Do not hold the ENGINE START/STOP button to
start the engine.
If the engine does not start, wait at least 10 seconds
before trying again.
