Radio reception factors
There are certain factors that may effect your radio reception.
•Distance/strength.The further an FM signal travels, the weaker it is.
The listenable range of the average FM station is approximately 40 km
(24 miles). This range can be affected by “signal modulation.” Signal
modulation is a process radio stations use to increase their
strength/volume relative to other stations.
•Terrain.Hills, mountains and tall buildings between your vehicle’s
antenna and the radio station signal can cause FM reception problems.
Static can be caused on AM stations by power lines, electric fences,
traffic lights and thunderstorms. Moving away from an interfering
structure (out of its “shadow”) returns your reception to normal.
•Station overload.Weak signals are sometimes captured by stronger
signals when you pass a broadcast tower. A stronger signal may
temporarily overtake a weaker signal and play while the weak station
frequency is displayed.
Principles of GPS (global positioning system) operation
Your system directs you based on information derived from global
positioning satellites, road maps stored on the DVD, sensors in your
vehicle and the desired destination. The system compiles all necessary
information to guide you to your selected destination. Space satellites
determine the vehicle’s current location and transmit position and time
signals to your car.
If the vehicle has been parked for a long period of time, the navigation
function may be temporarily unresponsive. The navigation system will
operate reliably again once GPS reception is available for a few minutes.
Limited GPS reception
System performance may be adversely affected if GPS reception is
interrupted or interference occurs over a distance of several miles. The
following are possible causes for GPS reception being interrupted. If the
vehicle is:
•in multi-story parking garages
•in tunnels and under bridges
•inside or in between buildings
•by forests or tree-lined avenues
•in heavy rain showers and thunderstorms
•in valleys and in mountainous regions

Note:If the indicator light blinks rapidly for two seconds and then turns
to a continuous light, proceed with Steps 6 through 8 to complete
programming of a rolling code equipped device.
6. At the garage door opener receiver (motor-head unit) in the garage,
locate the “learn” or “smart” button (usually near where the hanging
antenna wire is attached to the unit).
7. Press and release the “learn” or “smart” button. (The name and color
of the button may vary by manufacturer.)
Note:There are 30 seconds in which to initiate Step 8.
8. Return to the vehicle and firmly press, hold for two seconds and
release the HomeLinkbutton. Repeat the press/hold/release sequence
again, and, depending on the brand of the garage door opener (or other
rolling code equipped device), repeat this sequence a third time to
complete the programming.
HomeLinkshould now activate your rolling code equipped device. To
program additional HomeLinkbuttons begin with Step 2 in the
“Programming” section. For questions or comments, please contact
HomeLink atwww.homelink.comor1–800–355–3515.
Gate Operator & Canadian Programming
During programming, your
hand-held transmitter may
automatically stop transmitting —
not allowing enough time for
HomeLinkto accept the signal
from the hand-held transmitter.
After completing Steps 1 and 2
outlined in the“Programming”
section, replace Step 3 with the following:
Note:If programming a garage door opener or gate operator, it is
advised to unplug the device during the “cycling” process to prevent
overheating.
•Continue to press and hold the HomeLinkbutton (note Step 3 in the
“Programming” section) while you press and release —every two
seconds(“cycle”) your hand-held transmitter until the frequency
signal has been accepted by the HomeLink. The indicator light will
flash slowly and then rapidly after HomeLinkaccepts the radio
frequency signal.
•Proceed with Step 4 in the “Programming” section.

For maximum vehicle performance, keep the following information in
mind when adding accessories or equipment to your vehicle:
•When adding accessories, equipment, passengers and luggage to your
vehicle, do not exceed the total weight capacity of the vehicle or of
the front or rear axle (GVWR or GAWR as indicated on the Safety
Compliance Certification label). Consult your authorized dealer for
specific weight information.
•The Federal Communications Commission (FCC) and Canadian Radio
Telecommunications Commission (CRTC) regulate the use of mobile
communications systems — such as two-way radios, telephones and
theft alarms - that are equipped with radio transmitters. Any such
equipment installed in your vehicle should comply with FCC or CRTC
regulations and should be installed only by a qualified service
technician.
•Mobile communications systems may harm the operation of your
vehicle, particularly if they are not properly designed for automotive
use.
•To avoid interference with other vehicle functions, such as anti-lock
braking systems, amateur radio users who install radios and antennas
onto their vehicle should not locate the Amateur Radio Antennas in
the area of the driver’s side hood.
•Electrical or electronic accessories or components that are added to
the vehicle by the authorized dealer or the owner may adversely affect
battery performance and durability.
