Driving Through Deep Standing
Water
NOTICE:
If you drive too quickly through deep puddles or
standing water, water can come in through your
engine's air intake and badly damage your
engine. Never drive through water that is slightly
lower than the underbody
of your vehicle. If you
can't avoid deep puddles or standing water, drive
through them very slowly.
Engine Coolant Heater (Option)
I
In very cold weather, 0" F (- 1 8°C) or colder, the engine
coolant heater can help. You'll get easier starting and
better fuel economy during engine warm-up. Usually,
the coolant heater should be plugged in a minimum of
four hours prior to starting your vehicle.
2-1s
ProCarManuals.com

To Use the Coolant Heater
1. Turn off the engine.
2. Open the hood and unwrap the electrical cord.
3. Plug it into a normal, grounded 1 10-volt outlet.
NOTICE:
After you’ve used the coolant heater, be sure to
store the cord as it was before, to keep
it away
from moving engine parts.
If you don’t, it could
be damaged.
How long should you keep the coolant heater plugged
in? The answer depends on the weather, the kind
of oil
you have, and some other things. Instead
of trying to list
everything here, we
ask that you contact your Aurora
retailer
in the area where you’ll be parking your vehicle.
The retailer can give you the best advice for that
particular area.

Engine Coolant Temperature Gage
This gage shows the engine coolant temperature.
If the gage pointer moves into the red warning zone,
your engine is hot. To prevent engine overheating, the
air conditioning compressor will
turn off automatically,
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”
in the Index.
If your coolant level is low, the message LOW ENGINE
COOLANT will appear 011 the Driver Information
Center. Check your coolant level as soon
as possible.
See “Engine Coolant”
in the Index.

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.

Engine Overheating
You will find a coolant temperature gage on your
Aurora’s instrunlent panel. Your information center
will
also display messages about engine overheating. See
“Coolant Temperature Gage“
in the Index.
Overheated Engine Protection Operating Mode
Should a low coolant condition exist and the message
HOT STOP ENGINE display, an overheat protection
mode which alternates firing groups of four cylinders
helps prevent engine damage. This operating mode
allows
YOLIP vehicle to be driven to a safe place in an
emergency; you may drive
up to 50 miles (80 km).
Towing a trailer in the overheat protection lnode should
be avoided.
NOTICE:
After driving in the “Overheated Engine
Protection Operating Mode,” to avoid engine
damage, allow the engine to cool before
attempting any repair. The engine oil may be

NOTICE:
If your engine catches fire because you keep
driving with no coolant, your vehicle can be
badly damaged. The costly repairs would not be
covered
by your warranty. See “Overheated
Engine Protection Operating Mode” in the Index.
If No Steam Is Coming From Your Engine
If you get the overheat warning but see or hear no
steam, the problem may not be too serious. Sometimes
the engine can get a little too hot
when you:
Climb a long hill on a hot day.
Stop after high speed driving.
Idle for long periods in traffic.
Tow a trailer.
If you get the overheat warning with no sign of steam,
try this for a minute or so:
1. Turn off your air conditioner.
2. Turn on your heater to full hot at the highest fan
speed and open the window as necessary.
3. If you‘re in a traffic jam, shift to NEUTRAL (N);
otherwise, shift to the highest gear while driving --
AUTOMATIC OVERDRIVE (@) or THIRD (3).
If you no longer have the overheat warning, you can
drive. Just to be safe, drive slower for about
10 minutes.
If the warning doesn’t come back
on, you can drive
normally.
If the warning continues, pull over, stop, and park your
vehicle right away.
If there‘s still no sign
of steam, you can idle the engine
for two or three minutes while you’re parked, to see if
the warning stops. But then,
if you still have the
warning,
turf? ofthe engine and get everyone out qf the
vehicle until it cools down. Also, see “Overheated
Engine Protection Operating Mode” listed previously
in
this section.
You may decide not to lift the hood but to get service
help right away.
