GMC SAVANA 2001 Owner's Manual

2-64
NOTICE:
If you keep driving your vehicle with this light
on, after a while, your emission controls may not
work as well, your fuel economy may not be as
good and your engine may not run as smoothly.
This could lead to costly repairs that may not be
covered by your warranty.
Reduced Engine Power
The REDUCED ENGINE
POWER light will come on
when the cooling system
temperature gets too hot
and the engine further
enters the engine coolant
protection mode.
See ªEngine Overheatingº in the Index for
further information.
Oil Pressure Gage
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 problem causing low
oil pressure. Check your oil as soon as possible.

2-65
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.
Security Light
This light will come on
briefly when you turn the
ignition key to START.
The light will stay on until the engine starts. If the light
flashes, the Passlock

System has entered a tamper
mode. If the vehicle fails to start, see ªPasslockº in
the Index.
If the light comes on continuously while driving and
stays on, there may be a problem with the Passlock
System. Your vehicle will not be protected by Passlock,
and you should see your GM dealer.

2-66 Daytime Running Lamps Indicator Light
You have this light on the
instrument panel. It will
light whenever the DRL are
on. It is also a reminder to
turn on your headlamps
when driving at night.
Check Gages Light
The CHECK GAGES light
will come on briefly when
you are starting the engine.
If the light comes on and stays on while you are driving,
check your coolant temperature and engine oil pressure
gages to see if they are in the warning zones.

2-67 Fuel Gage
United States Canada
The fuel gage, when the ignition is on, tells you about
how much fuel you have left in your tank.The gage will first indicate empty before you are out of
fuel, and you should get more fuel as soon as possible.
Listed are four situations you may experience with your
fuel gage:

At the gas station, the fuel pump shuts off before the
gage reads full.

It takes a little more or less fuel to fill up than the
fuel gage indicated. For example, the gage may have
indicated the tank was half full, but it actually took a
little more or less than half the tank's capacity to fill
the tank.

The gage moves a little when you turn a corner or
speed up.

The gage doesn't go back to empty when you turn
off the ignition.
None of these indicate a problem with the fuel gage.

Comfort Controls
This section tells you how to make your air system
work for you.
With these systems, you can control the heating, cooling
and ventilation in your vehicle.
Heater Controls
If your vehicle does not have air conditioning, your
heater controls will look like this.
Fan Knob
The knob on the left side of the heating system control
panel regulates the fan speed. The knob has four speed
positions. To increase airflow, turn the knob toward HI.To decrease airflow, turn it toward LO. To turn the fan
off, turn the mode knob on the far right to OFF.
Temperature Knob
The middle knob on the control panel regulates the
temperature of the air flowing into your vehicle. Turn
the knob toward the red area for warmer air. Turn the
knob toward the blue area for cooler air.
Mode Knob
The right knob changes the heater setting.
VENT: This setting directs air through the
instrument panel vents.
BI-LEVEL: This setting divides airflow between
the heater floor vents and instrument panel vents.
HEAT: This setting directs air through the heater
floor vents.
HEAT/DEFOG: This setting divides airflow
between the heater floor vents and windshield.
DEFROST: This setting directs air through the
windshield defroster vents. This setting is used to
remove fog or ice from the windshield.

3-3 Heater/Air Conditioning Controls
(If Equipped)
If your vehicle has air conditioning, your heater/air
conditioning controls will look like this.
Before using your vehicle's air conditioning, open the
windows to clear the vehicle of hot air.Fan Knob
The knob on the left side of the heating system control
panel regulates the fan speed. The knob has four speed
positions. To increase airflow, turn the knob toward HI.
To decrease airflow, turn it toward LO. To turn the fan
off, turn the mode knob on the far right to OFF.
Temperature Knob
The middle knob on the control panel lets you select the
temperature of the air flowing into the passenger
compartment of your vehicle. This knob will allow you to
adjust the air temperature independently of the function knob
setting. Turn the knob toward the red area for warmer air.
Turn the knob toward the blue area for cooler air.
Mode Knob
The right knob on the control panel changes the
heater/air conditioning setting.
MAX A/C: Turn the right knob to MAX A/C for
maximum cooling. This setting puts the system in the
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,
turn the knob clockwise to place the air conditioning
system in the A/C mode.

3-4
A/C: This setting is used for normal cooling on hot
days. It cools outside air and directs it through the
instrument panel outlets.
BI-LEVEL A/C: This setting divides airflow
between the heater floor vents and instrument panel
vents. The air conditioning compressor will cycle
continuously in this setting as long as the outside air
temperature is warm enough to activate the compressor.
VENT: This setting directs air through the
instrument panel vents.
HEAT: This setting directs air through the heater
floor vents. It is useful for cold weather.
HEAT/DEFOG: This setting divides airflow
between the heater floor vents and the windshield. In the
blended position, the air conditioning compressor is
automatically activated to dehumidify the air.
DEFROST: This setting directs air through the
windshield defroster vents. It is useful when you have
fog or ice on the windshield.
Rear Heater (Without Air Conditioning)
(If Equipped)
If you have a rear heater (without rear air conditioning),
the control is located on the instrument panel.
To increase and decrease the flow of heated air to the
rear floor vents, turn the thumbwheel marked REAR
HEAT to the speed you want.
The thumbwheel has three speed positions. To increase
the flow of heated air, turn the thumbwheel toward
HIGH. To turn the fan off, turn the control to OFF.

3-5 Rear Air Conditioning and Rear Heater
(If Equipped)
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 ControlTo 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 counterclockwise
for floor vent airflow or clockwise 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 knob on the left
side of the control panel to the desired fan speed.
To activate the rear control, turn the fan knob on the
front control to REAR CNTL.

3-6
Rear Passenger Control
The rear control works just like the front control. It will
allow second seat passengers to adjust the controls if the
front control is switched to the rear position.
Air Conditioning
Before using your vehicle's air conditioning, open the
windows to clear the vehicle of hot air. This reduces the
time it takes for your vehicle to cool down. Then keep
your windows closed for the air conditioner to work at
its best.
You can use MAX A/C with the temperature knob in the
blue area when it's really hot outside and you need to
cool the inside air quickly. MAX A/C lets in only a little
air from the outside.
If you first use MAX A/C, you can then use A/C with
the temperature knob in the blue area, as soon as the
vehicle has cooled down, so outside air will be going
through your vehicle.
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.
When the air conditioning is on, you may notice a slight
increase or decrease in engine speed, due to compressor
operation. This is normal because the system is
designed to cycle the compressor on and off to keep
the desired temperature.
