Standard Cluster Digital Cluster
The
oil pressure gage shows the engine oil pressure in psi (pounds per
square inch) when the engine is running. Canadian vehicles indicate
pressure in kPa (kilopascals). Oil pressure may vary with engine speed,
outside temperature and oil viscosity, but readings above the low pressure
zone indicate the normal operating range.
A reading in the low pressure zone may be caused by a dangerously low oil
level or other problems causing low
oil pressure.
On the digital cluster, a box around the oil pressure symbol will begin to
flash when the oil pressure
is low.
A CAUTION:
Don’t keep driving if the oil pressure is low. If you do, your
engine can become
so hot that it catches fire. You or others could
be burned. Check your oil
as soon as possible and have your
vehicle serviced.
NOTICE:
Damage to your engine from neglected oil problems can be
costly and
is not covered by your warranty.

Standard Cluster Digital
Cluster
VOLTS
When your engine is not running, but the ignition is on (in the RUN
position), the gage shows your battery's state of charge in DC volts. When
the ignition
is running, the gage shows the condition of the charging system.
Readings between the low and high warning zones indicate the normal
operating range.
Readings in the low warning zone may occur when a large number of
electrical accessories are operating
in the vehicle and the engine is left at an
idle for an extended period. This condition
is normal since the charging
system is
not able to provide full power at engine idle. As engine speeds are
increased, this condition should correct itself as higher engine speeds allow
the charging system to create maximum power.
On the digital cluster, a box around the voltmeter symbol will begin the
flash when the charging system needs service.
You can only drive for a short time with the readings
in either warning zone.
If
you must drive, turn off all unnecessary accessories.
Readings in either warning zone indicate a possible problem in the electrical
system. Have the vehicle serviced as soon as possible.

If your vehicle does
not have air
conditioning, your
heater controls will
look like this.
Fan Lever
- The top lever has four positions. To increase the air flow,
move the lever toward
HIGH. To decrease the air flow, move it toward OFF.
Temperature Lever - This lever is below the fan lever and selects the
temperature
of the air flowing into your vehicle. Move the lever up for
warmer air. Move the lever down for cooler air.
Function Lever
- This lever is below the fan lever and can be moved to
five different functions.

Downloaded from www.Manualslib.com manuals search engine DEFROST-The setting with the defrost symbol operates the defroster. Most
of the air comes out near the windshield, with some going to the floor vents and
front side windows. Use
this when you get fog or ice on the windshield.
HTR (Heater) - Most of the air comes out near the floor. The rest comes
out from the defroster
vents under the windshield and at the front side
windows. This is best for cold weather.
VENT
- The air comes out at the vents on your instrument panel.
BLEND (Position
1) - With this setting, the heated outside air comes out
both
the heater vents and defroster vents. The lever can be positioned
anywhere between to adjust the proportion of air coming through each
vent.
Adjust the temperature lever for warmer or cooler air.
BLEND (Position
2) - With this setting, the heated outside air comes out
both the instrument panel vents and heater vents. The lever can be
positioned anywhere between
to adjust the proportion of air coming through
each
vent. Adjust the temperature lever for warmer or cooler air.
Heater/Air Conditioning Controls
If your vehicle has air
conditioning, your
heatinghir
conditioning controls
will

Downloaded from www.Manualslib.com manuals search engine Rear Air Conditioning (Option)
You may have rear air
conditioning. The rear
air conditioning
switch
is located
above the radio at the
top
of the instrument
panel. Slide the lever
toward
HI for cooler
air in the rear
area.
Slide the lever to OFF
to turn the system off.
If your vehicle has rear air conditioning, setting it on LO may enhance front
A/C performance by allowing trapped refrigerant in rear lines to circulate.
The system will only send cooled air if the front system is on. It can still
be
used to circulate air, even if the front system is off.
Before
using the rear air conditioning, open the windows to clear the vehicle
of hot air. Close the windows when using the system.
Rear Window Defogger (Option)
If your vehicle has this option, the rear window will have lines running
across the glass. These lines heat your window.
For best results, clear the window of as much snow or ice as possible before
using the
rear window defogger.
To
turn on the rear
window defogger, find
the switch marked
REAR DEFOG on
your instrument panel
to the left of the
steering column. Press
the top
of this switch
until the light in the
switch comes on, then
release it.
The rear window defogger will only work when the ignition switch
is in the
RUN position.

Downloaded from www.Manualslib.com manuals search engine You can turn the defogger off at any time by pressing the bottom of the switch.
The defogger will shut itself off after several minutes
so that the glass does not
get too hot. If the window still isn’t clear, turn the defogger on again.
NOTICE:
Scraping the inside of your rear window could cut and damage
the defogger. Your warranty would not cover this damage. And
don’t put decals there, you might have to scrape them
off.
Ventilation System
Your vehicle’s ventilation system supplies outside air to the inside of your
vehicle when it is moving. With the side windows closed, air will flow into
the front air inlet grilles at the base of
the windshield, through the vehicle
and out the rear air exhaust valves. Outside air will also enter the vehicle
when the heater or the air conditioning fan is running.
Venfilation Tips
0 Keep the hood and front air inlet free of ice, snow, or any other
obstruction (such as leaves). The heater and defroster will work far
better, reducing the chance of fogging the inside of your windows.
0 When you enter a vehicle in cold weather, turn the blower fan to HIGH for a
few moments before driving
off. This helps clear the intake ducts of snow and
moisture, and reduces the change
of fogging the inside of your windows.
0 Keep the air path under the front seats clear of objects. This helps air to
circulate throughout your vehicle.
