Climate Controls
Electronic Climate Control System
With this system, you can control the heating, cooling
and ventilation in your vehicle. Your vehicle also
has a flow-through ventilation system described later in
this section.
You can select different comfort control settings for the
driver and passengers.
Driver’s Side Temperature Knob
The driver’s side knob is used to adjust the temperature
of the air coming through the system on the driver’s
side. The temperature can be adjusted even if the
system is turned off. This is possible since outside air
will always
flow through the system as the vehicle
is moving forward unless it is set
to recirculation mode.
See “Recirculation” later in this section.
Turn the knob counterclockwise or clockwise
to lower or
increase the cabin temperature. The display will show
the temperature setting decreasing or increasing and an
arrow pointing
to the driver will be displayed under
and
to the left of the temperature setting.
Passenger’s Side Temperature Knob
The passenger’s side knob can be used to change the
temperature of the air coming through the system
on the passenger’s side
of the vehicle. The temperature
can be adjusted even
if the system is turned off. This
is possible since outside air will always flow through the
system as the vehicle is moving forward unless
it is
set
to recirculation mode. See “Recirculation later” in
this section.

Turn the knob counterclockwise or clockwise to lower or
increase the cabin temperature. The display will show
the temperature setting decreasing or increasing and an
arrow pointing
to the passenger will be displayed
under and
to the right of the temperature setting.
The passenger’s temperature setting can be set
to
match the driver’s temperature setting by pressing and
holding the AUTO button for four seconds. Both the
driver and passenger arrows will be displayed.
Automatic Operation
AUTO (Automatic): When automatic operation is
active the system will control the inside temperature, the
air delivery, and the fan speed.
0 (Off): Press this button to turn off the entire climate
control system. Outside air will still enter the vehicle,
and will be directed
to the floor. This direction can
be changed by pressing the mode button. The
temperature can also be adjusted using either
temperature knob. Press the up or down arrows on the
fan switch, the defrost button, the AUTO button, or
the air conditioning button
to turn the system on when it
is off.
Use the steps below to place the entire system in
automatic mode:
1. Press the AUTO button.
When AUTO is selected, the display will change
to
show the current driver’s set temperature, delivery
mode and fan speed. Press the AUTO button again
within five seconds
to display the passenger’s set
temperature.
If the driver and passenger’s temperature settings
are not the same, the opposite side temperature
setting will be displayed for an additional five
seconds. To make the passenger’s temperature the
same as the driver’s press and hold the AUTO
button for approximately four seconds.
When auto is selected, the air conditioning operation
and air inlet will be automatically controlled. The
air conditioning compressor will run when the
outside temperature is over approximately
40°F
(4°C). The air inlet will normally be set to outside air.
If it’s hot outside, the air inlet may automatically
switch
to recirculate inside air to help quickly cool
down your vehicle. The light on the button will
illuminate in recirculation.

When using the system in auto mode, find your comfort
setting by placing the temperature control
to 74°F
(23°C) and allowing about 20 minutes for the system to
regulate. Then adjust the temperature setting as
necessary. If you choose full cold
60” F (15”C), the
system will remain at the maximum cooling setting.
If you choose full hot 90 F (32”C), the system will remain
at the maximum heat setting.
Climate Controls Personalization
You can store and recall the climate control settings for
temperature, air delivery mode and fan speed for
two different
drivers. The personal ch~i~e settings
recalled are determined by the transmitter used
to enter
the vehicle.
After the button with the unlock symbol on a remote
keyless entry transmitter is pressed, the climate control
will adjust
to the last settings of the identified driver.
The settings can also be changed by pressing one of the
memory buttons
(1 or 2) located on the driver’s door.
When adjustments are made, the new settings are
automatically saved for that driver.

fixed
so it will be ready to warn you if there’s a
problem.
If the light comes on while you are driving, pull off the
road and stop carefully. You may notice that the pedal
is
harder to push. Or, the pedal may go closer to the
floor.
It may take longer to stop. If the light is still on,
have
the vehicle towed for service. See Towing
Your Vehicle on page 4-44.
Your brake system may not be working
properly
if the brake system warning light is
on. Driving with the brake system warning light
on can lead to an accident.
If the light is still
on after you’ve pulled off the road and stopped
carefully, have the vehicle towed for service.
Anti-Lock Brake System

With the anti-lock brake
system, this light will come
on when you start your
engine and may stay on for
several seconds.
That’s normal. If the light doesn’t come on then, have
it
fixed so it will be ready to warn you if there is a
problem.

If the light stays on, or comes on when you’re driving,
your vehicle needs service. You will also hear a
chime sound when the light is on steady.
If the regular
brake system warning light isn’t on, you still have
brakes, but you don’t have anti-lock brakes.
If the
regular brake system warning light is also on you don’t
have anti-lock brakes and there’s a problem with
your regular brakes. In addition to both lights, you will
also hear a chime sound on the first occurrence of
a problem and each time the car is shut off and then
restarted. See Brake System Warning Light on
page
3-34.

Canada
This gage shows the engine coolant temperature.
It also provides an indicator
of how hard your vehicle is
working. During a majority of the operation, the gage
will read 21
0°F (100°C) or less. If you are pulling a load
or going up hills, it is normal for the temperature to
fluctuate and approach the 250°F (122°C) mark.
If the
gage reaches the 260°F
(125°C) mark, it indicates
that the cooling system
is working beyond its capacity.
See Engine Overheating on page
5-25.

A reading in the low pressure zone may be caused by a
dangerously low oil level or some other problem
causing
low oil pressure. Check your oil as soon as
possible. See
Engine Oil on page 5-13.
DL.. t kc-> dl - - jng if -..3 oil pressure is IOL- If
you do, your engine can become
