Features
HomeLink® Universal Transceiver
The HomeLink ® Universal Transceiver can be pr ogrammed 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 wi th 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 bu ttons, and proceed to
step 1.
• If you are training the second or third
button, go directly to step 1.
■Important Safety Precautions
1HomeLink ® Universal Transceiver
HomeLink® is a registered tra demark of Gentex
Corporation.
Before programming HomeLi nk to operate a garage
door opener, confirm that the opener has an external
entrapment protection system, such as an “electronic
eye,” or other safety and reverse stop features. If it
does not, HomeLink may not be able to operate it.

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 wheel s, 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. 376
•Make sure there are no people or objects 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.

■Interior Checks1Interior Checks
The headlight aim is set by the factory, and does not
need to be adjusted. Howeve r, if you regularly carry
heavy items in the cargo area or tow a trailer, have
the aiming readjusted at a dealer or by a qualified
technician.

uuTowing a Trailer uTowing Preparation
264
Driving
Towing equipment varies by the size of your trailer, how much load you are towing,
and where you are towing.
■Hitches
The hitch must be of an approved type and properly bolted to the underbody.
■Safety chains
Always use safety chains when you tow a trailer. Leave enough slack to allow the
trailer to turn corners easily, but do not allow the chains to drag on the ground.
■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 brake s: 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 w ill lower braking effectiveness and create a
potential hazard.
■Additional towing equipment
Many states and provinces/territories requi re special outside mirrors when towing a
trailer. Even if mirrors are not required in your locale, you should install special
mirrors if visibility is restricted in any way.
■Towing Equipment and Accessories1Towing Equipment and Accessories
Make sure that all equipment is properly installed and
maintained, and that it meets federal, state, province/
territory, and lo cal regulations.
Consult your traile r sales or rental agency if any other
items are recommended or required for your towing
situation.
The lighting and wiring of tra ilers can vary by type
and brand. If a connector is required, it should only
be installed by a qua lified technician.

Trailer lights and equipment must comply with federal, state, province/territory, and
local regulations. Check with your local trailer sales or rental agency for the
requirements in the area where you plan to tow.
Your trailer lighting connector is located behind the left side panel in the cargo area.
Each pin’s purpose and wiring co lor code are shown in the image.
When using a non-Acura trailer lighting ha rness and converter, get the connector
and pins for your vehicle from a dealer.

• Have the trailer properly serviced and keep it in good condition.
• Make sure that all the weights and load in the vehicle and trailer are within limits.
2Towing Load Limits P. 263
•Securely attach the hitch, safety chains, and other necessary parts to the trailer.
• Securely store all the items in and on the tr ailer so that they do not shift while
driving.
• Check if the lights and brakes on the trailer are working properly.
• Check the pressures of the traile r tires, including the spare.
• Drive slower than normal.
• Obey posted speed limits for vehicles with trailers.
• Use the
(D position when towing a trailer on level roads.
• Turn more slowly and with a wider turning arc than normal.
• Allow more time and distance for braking.
• Do not brake or turn suddenly.
• Monitor your temperature gauge. If it nears the red (Hot) mark, turn off the
climate control system and reduce speed. Pull to the side of the road safely to cool
down the engine if necessary.
• Shift to the
(S position if the transmission shifts frequently.

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 de fogger 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. Cons ult 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 batte ry in the keyless
access remote is weak. 2 If the Keyless Access Remote Battery is
Weak P. 415
The engine may not start if the keyless access remote
is subjected to strong radio waves.
You do not need to hold the ENGINE START/STOP
button to start the engine.
If the engine does not start, wait at least 30 seconds
before trying again.
