Theft
Vehicle theft is big business, especially in some cities.
Although your vehicle
has a number of theft-deterrent
features, we know
that nothing we put on it can make it
impossible to steal. However, there are ways
you can help.
Key in the Ignition
If you leave your vehicle with the keys inside, it’s an
easy target for joy riders or professional thieves
-- so
don’t do it.
When you park your vehicle
and open the driver’s door,
you’ll hear a tone reminding you
to remove your key from
the ignition and take it with
you. Always do this. Your
steering wheel will be locked, and
so will your ignition
and transmission. And remember
to lock the doors.
Parking at Night
Park in a lighted spot, close all windows and lock your
vehicle. Remember
to keep your valuables out of sight.
Put them in a storage area, or take them with you.

ANTI -
LOCK
United States Canada
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 stays
on, or comes on when you’re driving,
your vehicle needs service. 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. See
“Brake System Warning Light” earlier in this section.
The anti-lock brake system warning light should come
on briefly when
you turn the ignition key to RUN. If the
light doesn’t come on then, have it fixed
so it will be
ready
to warn you if there is a problem.
Engine Coolant Temperature (I ~ - -:
This gage shows the engine
coolant temperature. If the
gage pointer moves into
the red area your engine is
too hot!
It means that your engine coolant has overheated. If
you have been operating your vehicle under normal
operating conditions,
you should pull off the road, stop
your vehicle, and turn
off the ‘engine as soon as possible.
The “Problems on the Road” section
of this
manual shows what to do. See “Engine Overheating”
in the Index.

Downloaded from www.Manualslib.com manuals search engine Comfort Controls Fan Knob
This section tells you how to make your air system
work for you. Your comfort control system uses
ozone-friendly
R- 134a refrigerant.
With these systems,
you can control the heating,
cooling and ventilation in your van. Your vehicle also
has a flow-through ventilation system described later
in this section. The
knob on the left side of the heating system control
panel controls the fan speed. The knob has four speed
positions. To increase airflow, move the knob toward
HI. To decrease airflow, move it toward LO. To turn the
fan off, move the mode knob on the
far right to OFF.
Temperature Knob
The middle knob on the control panel lets you select the
relative temperature
of the air flowing into the passenger area
of your vehicle. This knob will allow you to adjust
the

relative air temperature independently of the function knob
setting. Move
the knob toward the red area for warmer air.
Move the knob toward the blue area for cooler
air.
Mode Knob
If your vehicle does not have air conditioning, your
heater controls will look like this. The
right knob changes the heater setting.

conditioning controls will look like
this.
Before using your vehicle’s air conditioning, open the
windows to clear the vehicle
of hot air.

panel controls
the fan speed. The knob has four speed
positions. To increase airflow, move the knob toward

recirculation mode and helps
to maximize your air
conditioner’s performance and your vehicle’s fuel
economy. This setting also cools the air the fastest. After
the vehicle’s interior reaches
a comfortable temperature,
move the knob
to the right to place the air conditioning
system in the
A/C mode.

Downloaded from www.Manualslib.com manuals search engine Rear Air Conditioning and Rear Heater
If your vehicle has a rear air conditioning and rear heater
system combination, controls are provided to regulate the
temperature, location and speed
of the airflow.
Front Passenger Control
To adjust the air temperature, turn the temperature knob
on the right side
of the control panel.
For warmer air, turn the knob toward the red area, and
for cooler air, turn the knob toward the blue area.
To regulate the airflow location, adjust the center knob
on the control panel. Turn the knob to the left for floor vent airflow
or to the right for headliner
vent air flow.
Generally, the upper vents are used for air conditioning
and the
floor vents for heating. The control knob can be
set to any blend setting.
To adjust the
airflow speed, turn the fan control knob on
the left side of the control panel to the desired blower setting.
To activate the rear control, move the fan knob on the
front control to REAR CNTL.
Rear Passenger Control
The rear control works just like the front control. It will
allow second seat passengers
to adjust the controls as
they desire.
