Cleaning the Video Screen
When cleaning the video screen,
use only a clean cloth dampened
with clean water. Use care when
directly touching or cleaning the
screen, as damage could result.
Rear Seat Audio (RSA)
System
Vehicles with this feature allow the
rear seat passengers to listen to
and control any of the music
sources: radio, CDs, DVDs, or other
auxiliary sources. However, the rear
seat passengers can only control
the music sources the front seat
passengers are not listening to
(except on some radios where dual
control is allowed). For example,
rear seat passengers can control
and listen to a CD through the
headphones, while the driver listens
to the radio through the front
speakers. The rear seat passengers
have control of the volume for each
set of headphones.The radio functionality is controlled
by both the RSA and the front radio.
Only one band can be tuned to at
one time. Changing the band on the
RSA or the front radio will change
the band on the other system,
if they are both sourced to the radio.
The RSA functions operate even
when the main radio is off. The front
audio system will display the
headphone icon when the RSA is
on, and will disappear from the
display when it is off.
Audio can be heard through wired
headphones (not included) plugged
into the jacks on the RSA. If the
vehicle has this feature, audio can
also be heard on Channel 2 of the
wireless headphones.
The audio system mutes the rear
speakers when the RSA audio is
active through the headphones.P(Power):
Press thePbutton to
turn the RSA on or off.
Volume: Turn this knob to increase
or to decrease the volume of the
wired headphones. The left knob
controls the left headphones and
the right knob controls the right
headphones.
SRCE (Source): Press this
button to switch between the radio
(AM/FM), XM™ (if equipped),
CD, and if the vehicle has these
features, DVD, front auxiliary, and
rear auxiliary.

When to Speak:A short tone
sounds after the system responds
indicating when it is waiting for a
voice command. Wait until the tone
and then speak.

calm and natural voice.
Audio System
When using the in‐vehicle Bluetooth
system, sound comes through
the vehicle's front audio system
speakers and overrides the audio
system. Use the audio system
volume knob, during a call, to
change the volume level. The
adjusted volume level remains in
memory for later calls. To prevent
missed calls, a minimum volume
level is used if the volume is turned
down too low.
Bluetooth Controls

steering wheel to operate the
in‐vehicle Bluetooth system. See
Steering Wheel Controls on

Climate Controls 8-7
H(Vent):Air is directed to the
instrument panel outlets.
)(Bi-Level): Air is divided
between the instrument panel and
floor outlets. Some air is directed
towards the windshield and side
window outlets.
6(Floor): Air is directed to the
floor outlets, with some to the
windshield, side window outlets,
and second row floor outlets. In this
mode, the system automatically
selects outside air.
-(Defog): This mode clears the
windows of fog or moisture. Air is
directed to the windshield, floor
outlets, and side window vents. In
this mode, the system turns off
recirculation and runs the air
conditioning compressor unless
the outside temperature is close to
freezing. The recirculation mode
cannot be selected while in the
defog mode.
0(Defrost): This mode removes
fog or frost from the windshield
more quickly. Air is directed to the
windshield and side window vents,
with some directed to the floor
vents. In this mode, the system
automatically forces outside air
into the vehicle and runs the air
conditioning compressor unless the
outside temperature is close to
freezing. The recirculation mode
cannot be selected while in the
defrost mode.
The passenger temperature
control cannot be activated while in
defrost mode. If the PASS button is
pressed, the button indicator flashes
three times and will not work. If the
passenger temperature buttons are
adjusted, the driver temperature
indicator changes. The passenger
temperature will not be displayed.
If vent, bi-level, or floor mode is
selected again, the climate control
system displays the previous
temperature settings. Do not drive the vehicle until all the
windows are clear.
#(Air Conditioning):
Press to
turn the air conditioning (A/C)
compressor on and off. An indicator
light comes on to show that the air
conditioning is on.
If this button is pressed when the
air conditioning compressor is
unavailable, the indicator flashes
three times and then turns off. If the air conditioning is on and the
outside temperature drops below a
temperature which is too cool for air
conditioning to be effective, the air
conditioning light turns off to show
that the air conditioning mode has
been canceled.
On hot days, open the windows long
enough to let hot inside air escape.
This helps to reduce the time it
takes for the vehicle to cool down.
It also helps the system to operate
more efficiently.

Driving and Operating 9-25
Notice:Cranking the engine for
long periods of time, by returning
the key to the START position
immediately after cranking has
ended, can overheat and damage
the cranking motor, and drain the
battery. Wait at least 15 seconds
between each try, to let the
cranking motor cool down.
2. If the engine does not start
after 5‐10 seconds, especially in
very cold weather (below −18°C
or 0°F), it could be flooded with
too much gasoline. Try pushing
the accelerator pedal all the way
to the floor and holding it there
as you hold the key in START
for up to a maximum of
15 seconds. Wait at least
15 seconds between each try, to
allow the cranking motor to cool
down. When the engine starts,
let go of the key and accelerator. If the vehicle starts briefly but
then stops again, repeat these
steps. This clears the extra
gasoline from the engine. Do not
race the engine immediately
after starting it. Operate the
engine and transmission gently
until the oil warms up and
lubricates all moving parts.
Notice: The engine is designed to
work with the electronics in the
vehicle. If you add electrical
parts or accessories, you could
change the way the engine
operates. Before adding electrical
equipment, check with your
dealer. If you do not, the engine
might not perform properly. Any
resulting damage would not be
covered by the vehicle warranty.Engine Heater
The engine coolant heater can
provide easier starting and better
fuel economy during engine
warm-up in cold weather conditions
at or below −18°C (0°F). Vehicles
with an engine heater should be
plugged in at least four hours before
starting. An internal thermostat in
the plug-end of the cord may exist
which will prevent engine coolant
heater operation at temperatures
above −18°C (0°F).
To Use the Engine Coolant
Heater
1. Turn off the engine.
2. Open the hood and unwrap
the electrical cord. The cord
is secured to the Engine
Compartment Fuse Block with
a clip. Carefully remove the
wire tie which secures the
electrical cord. Do not cut the
electrical cord.
