a fdst-pulsed chime
will sound, and the message
ENGINE
HOT ... A/C OFF will appear in the information
center.
As the engine cools down, the air conditioning
compressor will automatically turn back on.
If the coolant temperature is over 26 1 OF (127”C), the
message
HOT ... STOP ENGINE will appear. It means
that your engine coolant has overheated.
If you have
been operating your vehicle under normal driving
conditions, you should pull off the road, stop your
vehicle and turn off the engine as soon as possible.
In “Problems on the Road,’? this manual shows what to
do. See “Engine Overheating”

Remember, you must reset the OIL LIFE or TRNS
FLUID yourself after each oil or transaxle fluid change.
It will not reset itself. Also, be careful not to reset the
OIL LIFE or TRNS FLUID accidentally at any time
other than when the oil or transaxle fluid has just been
changed. It can’t be reset accurately until the next oil or
transaxle fluid change.
The Driver Information Center does not replace the need
to maintain your vehicle as recommended in the
Maintenance Schedule in this manual. Also, the oil
change reminder will not detect dusty conditions or
engine malfunctions that may affect the oil. If you drive
in dusty areas, change your oil after every
3,000 miles
(5 000 km) or three months, whichever comes first,
unless the
DIC instructs you to do so sooner. Also, the
oil change reminder does not measure how much oil you
have in your engine.
So, be sure to check your oil level
often.. See “Engine Oil” in the Index.
Check Oil Level Warning
When CHECK OIL LEVEL appears, it indicates that the
engine oil level is
1 to 1 1/2 quarts (0.9 L to 1.4 L) low.
The message will appear only if the engine is running
and it’s been at least eight minutes since the engine was
last running. If the message appears, check the oil
dipstick level. If
it reads low, your oil level should be
brought up to the proper level (see “Engine Oil” in the\

Index). After bringing the oil to the proper level, the
ignition must be
off for eight minutes to allow the
majority of oil to drain into the oil pan.

Comfort Controls and Audio Systems
In this section you'll find out how to operate the comfort
control system and audio systems offered with your
Aurora.
Be sure to read about the particular system
supplied with your vehicle.
Automatic Electronic Climate Control
With this system, you can control the ventilation, heating
and air conditioning
in your vehicle, or you can use the
automatic setting. Your vehicle also has the flow-through
ventilation system described later
in this section.
Overview
This climate control system is designed for
set-and-forget operation. That means that once you set a
temperature
you shouldn't keep changing it; allow about
20 minutes after starting the vehicle for the system to
regulate itself before you make another adjustment.
Immediately selecting
90°F (32°C) will not warm the
vehicle any faster than selecting 75°F (16"C), which is
the average comfortable temperature.
With this system, you can manually control the
ventilation, heating and air conditioning
in your vehicle,
or you can use the automatic setting. Your control
setting is remembered for the next time you start your
vehicle.
If the system was in DEF (Defrost), however, it
comes back on in AUTO if the engine is shut off for
more than
40 minutes.
A computer monitors operation of your Automatic
Electronic Climate Control System.
If your set
temperature flashes on
the digital screen for almost two
minutes after starting your vehicle,
the system is

AUTO-PUSH: To allow the system to automatically
control
the temperature, air distribution and Fdn speed:
1. Set the temperature you want with the colored
temperature buttons.
2. Press the AUTO-PUSH switch. The AUTO light will
appear below the selector.
To maintain proper comfort, the air flow direction
will
automatically change with increases or decreases in
outside temperature, interior temperature, or sun load.
After starting a cold engine, there may be up to a
four-minute delay before the fan is turned on. The fan
will automatically increase
in speed as the coolant
temperature rises.
AUTO FAN: Sets the fan speed. Turn this knob to the
right to raise
the fan speed, to the left to lower the fan
speed. The fan speed
will be displayed by the lights
around the knob (except
in the AUTO mode).
Use the following controls when you wish to override
the AUTO setting.
Directional Controls
When the AUTO-PUSH knob is pressed, the fan speed
will go
to AUTO unless you select a different speed.
After
you turn the knob to a directional control, the set
interior temperature
will be displayed for about five
seconds,
then the outside temperature will be displayed
"ri Upper: Directs air flow through the upper air
outlets
in the instrument panel.
f0 /I' Bi-Level: Use on cool, but sunny days. This
setting brings
in the outside air, but directs it in two
ways. The cool air is directed
to the upper portion of
your body through the instrument panel outlets, but most
warmed air is directed through the heater ducts and
a
little to the defrost and side window vents. At times, this
temperature difference may be more apparent than
others.

Air Conditioning
The air conditioner cools, dehumidifies, and filters the
air for the inside of the vehicle.
The air conditioner compressor
is enabled in all modes.
However, when the outside temperature is below
42" F
(6"C), the compressor will not operate. When the air
conditioner is on, you may sometimes notice slight
changes
in your vehicle's engine speed and power. This
is normal, because the system is designed to cycle the
compressor
on and off to keep the desired cooling and
help fuel economy.
The air conditioning is always enabled
in defog or
defrost. In any other mode,
you can select or shut off the
air conditioning as desired by pressing
A/C ON. The
indicator light will glow while the air conditioning is
enabled. For maximum
continued cooling, press the blue
temperature button repeatedly until the display reads
60" F (16°C) and press the A/C ON button. Using the
upper vents will cause
you to feel cooler more quickly.
The direction of
the cool air can be controlled by
adjusting, or turning off, the outlets in the dash. Aiming
them over your shoulder will benefit both front and rear
passengers. Back seat passengers can also redirect air
flow using the vents at the rear
of the center console.
On hot days, open the windows long enough to let the
hot inside air out. This reduces the time the air
conditioner's compressor will have to run, which should
help fuel economy.

Extended Idling with Automatic Electronic Climate Control
Extended idling is not recommended. See “Engine
Exhaust’’
in the Index.
Steering Wheel Touch Controls for Climate Control
Some heating and
cooling controls can be
adjusted at
the steering
wheel. Other touch
controls also operate some audio controls.
See “Steering Wheel
Touch Controls for
Audio System” later
in
this section. Press
the upper part
of the fan symbol to increase the fan
speed; press the lower part of the control to reduce the
fan speed.
Press
TEMP once to display the set temperature. Then press
the upper part of the control to raise the inside temperature \
setting; press the lower part to lower the setting.
Flow-Through Ventilation System
Your Aurora’s flow-through ventilation system supplies
outside air into the vehicle when
it is moving. Outside
air will
also enter the vehicle when the heater or the air
conditioning fan is running.
Ventilation Tips
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.
Keep the air path under the front seats clear of
objects. This helps air
to circulate throughout your
vehicle.
