page 13‑20 for information
regarding Part 15 of the Federal
Communications Commission (FCC)
rules and Industry Canada
Standards RSS-GEN/210/220/310.
If there is a decrease in the RKE

for transmitter programming.
Battery Replacement
Replace the battery if the REPLACE
BATTERY IN REMOTE KEY
message displays in the DIC.
Notice:When replacing the
battery, do not touch any of the
circuitry on the transmitter. Static
from your body could damage the
transmitter.
To replace the battery:
1. Separate the transmitter with a flat, thin object, such as a flat
head screwdriver.
.Carefully insert the tool into
the notch located along the
parting line of the
transmitter. Do not insert
the tool too far. Stop as
soon as resistance is felt.
.Twist the tool until the
transmitter is separated.
2. Remove the old battery. Do not use a metal object. 3. Insert the new battery, positive
side facing down. Replace with a
CR2032 or equivalent battery.
4. Snap the transmitter back together.
Remote Vehicle Start
If available, this feature allows you
to start the engine from outside of
the vehicle. It may also start up the
vehicle's heating or air conditioning
systems and rear window defogger.
Normal operation of the system will
return after the key is turned to the
ON/RUN position.
If the vehicle has an automatic
climate control system, the climate
control system will default to a
heating or cooling mode depending
on the outside temperatures. If the
vehicle does not have an automatic
climate control system, the system
will turn on at the setting the vehicle
was set to when the vehicle was
last turned off.

This message displays and a chime
may sound when the cooling system
temperature gets too hot and the
engine further enters the engine
coolant protection mode. See
Engine Overheating on page 10‑21
for more information.
This message also displays when
the vehicle's engine power is
reduced. Reduced engine power
can affect the vehicle's ability to
accelerate. If this message is on,
but there is no reduction in
performance, proceed to your
destination. The performance may
be reduced the next time the vehicle
is driven. The vehicle may be driven
at a reduced speed while this

listen to the radio, CDs, DVDs,
MP3s, DVD-As, or any auxiliary
source connected to A/V jacks or
the auxiliary input jack, if the vehicle
has this feature. The wireless
headphones have a power button,
channel 1 or 2 switch, and a volume
control.
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 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.
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.
Headphones should be worn with
the headband over the top of the
head for best audio reception. The
symbol L (Left) appears on the
outside bottom edge of the ear cup
and should be positioned on the left
ear. The symbol R (Right) appears
on the outside bottom edge of the
ear cup 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.
To purchase replacement ear pads,
call 1-888-293-3332, then prompt
zero (0), or contact your dealer.

10-28 Vehicle Care
Always clean the brake fluid
reservoir cap and the area around
the cap before removing it. This
helps keep dirt from entering the
reservoir.
{WARNING
With the wrong kind of fluid in the
brake hydraulic system, the
brakes might not work well. This
could cause a crash. Always use
the proper brake fluid.
Notice
.Using the wrong fluid can
badly damage brake
hydraulic system parts. For
example, just a few drops of
mineral-based oil, such as
engine oil, in the brake
hydraulic system can
damage brake hydraulic
system parts so badly that
they will have to be replaced.
Do not let someone put in
the wrong kind of fluid.
.If brake fluid is spilled on the
vehicle's painted surfaces,
the paint finish can be
damaged. Be careful not to
spill brake fluid on the
vehicle. If you do, wash it off
immediately.
Battery
If the vehicle is a Hybrid, see the
Hybrid Supplement for more
information.
This vehicle has a maintenance free
battery (or batteries). Refer to the
replacement number on the original
battery label when a new battery is
