Display: In the full AUTO mode, the automatic dual
climate control system display will show the driver set
temperature and an arrow pointing to the driver’s side. An
arrow pointing to the passenger’s side will display
if both
sides are set to the same temperature.
If the temperature
settings are not the same, the opposite side temperature
setting will be displayed for an additional five seconds.
During the five second status display the current mode
and blower speed will be displayed.
Driver’s Side Temperature Knob: Turn this knob
clockwise or counterclockwise to manually raise or lower
the temperature on the driver’s side of the vehicle.
The display will show the temperature setting decreasing
or increasing and an arrow pointing to the driver. The
temperature can be adjusted even
if the system is
turned
off. If the passenger’s set temperature has not
been adjusted this knob controls both the driver’s
and passenger’s air temperature. The temperature to
the rear seat area is controlled by using this knob.
Passenger’s Side Temperature Knob: Turn this knob
clockwise or counterclockwise to manually raise or
lower the temperature on the passenger’s side of the
vehicle. The display will show the temperature
setting decreasing or increasing and an arrow pointing
to the passenger. The temperature can be adjusted
even
if the system is turned off. Once this knob is used,
the passenger’s temperature will remain independent
of the driver’s until the AUTO button is pressed and held
for approximately four seconds.
Automatic Operation
AUTO (Automatic): When automatic operation is
active the system will control the inside temperature, the
air delivery, and the fan speed.
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.

Your vehicle can perform very well in emergencies like
these. First apply your brakes.
See
Braking on page 4-6. It is better to remove as much
speed as you can from a possible collision. Then
steer around the problem, to the left
or right depending
on the space available.
An emergency like this requires close attention and a
quick decision. If you are holding the steering wheel at
the recommended
9 and 3 o’clock positions, you
can turn it a full 180 degrees very quickly without
removing either hand. But you have to act fast, steer
quickly, and just as quickly straighten the wheel
once you have avoided the object. The
fact that such emergency situations are always
possible is a good reason
to practice defensive driving
at all times and wear safety belts properly.
QUADRASTEERTM
The QUADRASTEERTM System has a control and
diagnostic module that monitors and records current
system status and operational information.
If your vehicle is equipped with the 4 Wheel Steer
system it has the ability to steer the vehicle with all four
wheels.
Once the
4 Wheel Steer mode is selected, it is
recommended
to leave the vehicle in this mode at all
times, and during all driving and weather conditions.
You can select this mode at any speed, however,
if you
are turning the system will not engage until the turn
is complete.
The 4 Wheel Steer system is equipped with three
different driving modes:
Two wheel steering (2)
Four wheel steering (4)
Four wheel steering with a trailer mode (q )

Q: What should I do if my vehicle stalls, or is

about to stall, and

make it up the hill?

do and there are some things you must not do.
First, here’s what you should do:
Push the brake pedal to stop the vehicle and keep
if from rolling backwards. Also, apply the parking
brake.
If your engine is still running, shift the transmission
to REVERSE (R), release the parking brake, and
slowly back down the hill as straight as possible in
REVERSE (R).
As you are backing down the hill, put your left hand
on the steering wheel at the
12 o’clock position.
This way, you’ll be able to tell
if your wheels
are straight and maneuver as you back down. It’s
best that you back down the hill with our wheels
straight rather than in the left or tight direction.
Turning the wheel too far to the left
or right
will increase the possibility of a rollover. Here are
some things you
must not do if you stall, or
are about to stall, when going up a
hill.
9 Never attempt to prevent a stall by shifting into
NEUTRAL
(N) to “rev-up” the engine and regain
forward momentum. This won’t work. Your vehicle
will roll backwards very quickly and you could
go out of control.
Instead, apply the regular brake to stop the vehicle.
Then apply the parking brake. Shift to
REVERSE (R), release the parking brake, and
slowly back straight down.
9 Never attempt to turn around if you are about to
stall when going up a hill. If the hill is steep
enough to stall your vehicle, it’s steep enough to
cause you to roll over
if you turn around. If you can’t
make it up the hill, you must back straight down
the hill.

While refueling, hang the fuel cap by the tether using
the hook located on the inside of the filler door.
To remove the fuel cap, turn it slowly to the left
(counterclockwise).
- -
If you get fuel on yourself and then something
ignites
it, you could be badly burned. Fuel can
spray out on you if you open the
fuel cap too
quickly. This spray can happen if your tank
is
nearly full, and is more likely in hot weather.
Open the fuel cap slowly and wait for any
“hiss” noise to stop. Then unscrew the cap all
the way.
Be careful not to spill fuel. Clean fuel from painted
surfaces as
soon as possible. See Cleaning the Outside
of Your Vehicle on page 5-88.

When you put the fuel cap back on, turn it to the right
(clockwise) until you hear a clicking sound. Make
sure you fully install the cap. The diagnostic system can
determine
if the fuel cap has been left off or improperly
installed. this would allow fuel
to evaporate into the
atmosphere. See
Malfunction Indicator lamp on
page 3-38.
Notice: If you need a new fuel cap, be sure to get
the right type. Your dealer can get one for you. If you get the wrong type,
it may not fit properly.
This may cause your malfunction indicator lamp to
light and may damage your fuel tank and emissions
system. See “Malfunction Indicator Lamp” in the
Index.
Filling a Portable Fue ‘~er
Never fill -)ortable fuel container while it is in
your vehicle. Static electricity discharge from
the container can ignite the gasoline vapor.
You can be badly burned and your vehicle
damaged if
this occurs. To help avoid injury to
you and others:
0 Dispense gasoline only into approved
containers.
Do not fill a container while it is inside a
vehicle,
in a vehicle’s trunk, pickup bed or
on any surface other than the ground.
0 Bring the fill nozzle in contact with the
inside of the fill opening before operating
the nozzle. Contact should be maintained until the filling
is complete.
Don’t smoke while pumping gasoline.

1. Park the vehicle on a
level surface. You can
remove the coolant
surge tank pressure
cap when the cooling
system, including
the coolant surge tank pressure cap and
upper radiator hose,
is no longer hot.
2. Turn the pressure cap slowly counterclockwise (left)
about one full turn.
If you hear a hiss, wait for that to
stop.
A hiss means there is still some pressure left.
3. Then keep turning the pressure cap slowly, and
remove
it.
