Remote Keyless Entry (RKE)
System
The Remote Keyless Entry (RKE) system operates on a
radio frequency subject to Federal Communications
Commission (FCC) Rules and with Industry Canada.
This device complies with Part 15 of the FCC Rules.
Operation is subject to the following two conditions:
1. This device may not cause interference.
2. This device must accept any interference received,
including interference that may cause undesired
operation of the device.
This device complies with RSS-210 of Industry Canada.
Operation is subject to the following two conditions:
1. This device may not cause interference.
2. This device must accept any interference received,
including interference that may cause undesired
operation of the device.
Changes or modications to this system by other than
an authorized service facility could void authorization to
use this equipment.If there is a decrease in the RKE operating range,
try this:
Check the distance. The transmitter may be too far
from the vehicle. Stand closer during rainy or
snowy weather.
Check the location. Other vehicles or objects may
be blocking the signal. Take a few steps to the
left or right, hold the transmitter higher, and
try again.
Check the transmitter’s battery. See “Battery
Replacement” later in this section.
If the transmitter is still not working correctly, see
your dealer/retailer or a qualied technician for
service.
Remote Keyless Entry (RKE)
System Operation
The Remote Keyless Entry (RKE) transmitter functions
work up to 195 feet (60 m) away from the vehicle.
There are other conditions which can affect the
performance of the transmitter. SeeRemote Keyless

Push the power button to turn on the headphones. An
indicator light located on the headphones comes
on. If the light comes on but there is intermittent sound
and/or static on the headphones, or if the indicator
light does not come on, the batteries might need to be
replaced. See “Battery Replacement” later in this
section for more information. Switch the headphones to
Off when not in use.
Infrared transmitters are located at the rear of the RSE
overhead console. The headphones shut off
automatically to save the battery power if the RSE
system and RSA are shut off or if the headphones are
out of range of the transmitters for more than
three minutes. If you move too far forward or step out of
the vehicle, the headphones lose the audio signal.
The headphones automatically turn off after four hours
of continuous use.
To adjust the volume on the headphones, use the
volume control located on the right side.
For optimal audio performance, the headphones must
be worn correctly. The symbol L (Left) appears on
the upper left side, above the ear pad and should be
positioned on the left ear. The symbol R (Right) appears
on the upper right side, above the ear pad and should
be positioned on the right ear.Notice:Do not store the headphones in heat or
direct sunlight. This could damage the headphones
and repairs will not be covered by the warranty.
Storage in extreme cold can weaken the batteries.
Keep the headphones stored in a cool, dry place.
If the foam ear pads attached to the headphones
become worn or damaged, the pads can be replaced
separately from the headphone set. See your
dealer/retailer for more information.
Battery Replacement
To change the batteries on the headphones:
1. Turn the screw to loosen the battery door located
on the left side of the headphones. Slide the
battery door open.
2. Replace the two batteries in the compartment.
Make sure that they are installed correctly, using
the diagram on the inside of the battery
compartment.
3. Replace the battery door and tighten the door
screw.
If the headphones are to be stored for a long period of
time, remove the batteries and keep them in a cool,
dry place.

Remote Control
To use the remote control, aim it at the transmitter
window at the rear of the overhead console and press
the desired button. Direct sunlight or very bright light
could affect the ability of the RSE transmitter to receive
signals from the remote control. If the remote control
does not seem to be working, the batteries might need
to be replaced. See “Battery Replacement” later in
this section. Objects blocking the line of sight could also
affect the function of the remote control.
If a CD or DVD is in the Radio DVD slot, the remote
control power button can be used to turn on the video
screen display and start the disc. The radio can also
turn on the video screen display. SeeRadio(s) on
page 3-85for more information.
Notice:Storing the remote control in a hot area or
in direct sunlight can damage it, and the repairs
will not be covered by the warranty. Storage
in extreme cold can weaken the batteries. Keep the
remote control stored in a cool, dry place.
Remote Control Buttons
O(Power):Press this button to turn the video screen
on and off.
P(Illumination):Press this button to turn the remote
control backlight on. The backlight automatically
turns off after seven to ten seconds if no other button is
pressed while the backlight is on.

Brake Adjustment
Every brake stop, the disc brakes adjust for wear.
Replacing Brake System Parts
The braking system on a vehicle is complex. Its many
parts have to be of top quality and work well together if
the vehicle is to have really good braking. The vehicle
was designed and tested with top-quality brake parts.
When parts of the braking system are replaced — for
example, when the brake linings wear down and new
ones are installed — be sure to get new approved
replacement parts. If this is not done, the brakes might
not work properly. For example, if someone puts in brake
linings that are wrong for the vehicle, the balance
between the front and rear brakes can change — for the
worse. The braking performance expected can change in
many other ways if the wrong replacement brake parts
are installed.
Battery
If the vehicle is a Two-mode Hybrid, see the Two-mode
Hybrid manual for more information.
This vehicle has a maintenance free battery. When it is
time for a new battery, see your dealer/retailer for
one that has the replacement number shown on the
original battery’s label. SeeEngine Compartment
Overview on page 5-14for battery location.
Warning:Battery posts, terminals, and related
accessories contain lead and lead compounds,
chemicals known to the State of California to cause
cancer and reproductive harm. Wash hands after
handling.
