Messages
A/C OFF DUE TO HIGH
ENGINE TEMP
This message displays when the
engine coolant becomes hotter than
the normal operating temperature.
To avoid added strain on a hot
engine, the air conditioning
compressor automatically turns off.
When the coolant temperature
returns to normal, the air
conditioning compressor turns back
on. The vehicle can continue to be
driven.
If this message continues to appear,
have the system repaired by your
dealer as soon as possible to avoid
damage to the engine.
ENGINE OVERHEATING—
IDLE ENGINE
This message displays when the
engine coolant temperature is too
hot. Stop and allow the vehicle to
idle until it cools down.
ENGINE OVERHEATED —
TURN VEHICLE OFF
This message displays and a
continuous chime sounds if the
engine cooling system reaches
unsafe temperatures for operation.
Stop and turn off the vehicle as
soon as it is safe to do so to avoid
severe damage. This message
clears when the engine has cooled
to a safe operating temperature.
Engine Oil Messages
CHANGE ENGINE OIL SOON
This message displays when the
engine oil needs to be changed.
When you change the engine oil, be

Depending on the engine speed, the
air conditioning compressor may
shut off and turn on again and a
slight change in A/C cooling and
engine performance may be
noticed. This is normal. The system
is designed to make adjustments to
help with fuel economy while still
maintaining the selected
temperature.
If the A/C is turned off, automatic
operation is canceled.

the ACC/ACCESSORY or LOCK/
OFF position.
The rear window defogger can be
set to automatic operation. See
“Climate and Air Quality” under
Vehicle Personalization 0132.
When auto rear defog is selected,
the rear window defogger turns on
automatically when the interior
temperature is cold and the outside
temperature is about 4 °C (40 °F)
and below. The auto rear defogger
turns off automatically after about
10 minutes.

Service
All vehicles have a label underhood
that identifies the refrigerant used in
the vehicle. The refrigerant system
should only be serviced by trained
and certified technicians. The air
conditioning evaporator should
never be repaired or replaced by
one from a salvage vehicle.
It should only be replaced by a new
evaporator to ensure proper and
safe operation.
During service, all refrigerants
should be reclaimed with proper
equipment. Venting refrigerants
directly to the atmosphere is harmful
to the environment and may also
create unsafe conditions based on
inhalation, combustion, frostbite,
or other health-based concerns.

Vehicle Care 241
{Warning
Heater and radiator hoses, and
other engine parts, can be very
hot. Do not touch them. If you do,
you can be burned.
Do not run the engine if there is a
leak. If you run the engine, it
could lose all coolant. That could
cause an engine fire, and you
could be burned. Get any leak
fixed before you drive the vehicle.
Caution
Using coolant other than
DEX-COOL®can cause
premature engine, heater core,
or radiator corrosion. In addition,
the engine coolant could require
changing sooner. Any repairs
would not be covered by the
vehicle warranty. Always use
DEX-COOL (silicate-free) coolant
in the vehicle.
Cooling System (Aero
Panel)
The aero panel enhances
aerodynamic efficiency and
improves fuel economy.
Remove the aero panel and bracket
to improve engine cooling and air
conditioning performance when
driving aggressively or in hot
weather. To remove the aero panel and
bracket:
Stingray Shown, Grand Sport and
Z06 Similar
1. Press up on the two indents at the bottom and lift the aero
panel off the bracket.
