When you enter a vehicle in cold weather, adjust the
mode knob to FLOOR and the fan to the highest
speed for a few seconds before driving off. This
helps clear the intake ducts of snow and moisture
and reduces 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.

If the error occurred while trying to play a CD in the
compact disc player or changer, the following conditions
may have caused the error:

The road is too rough. The disc should play when the
road is smoother.

The disc is dirty, scratched or wet.

The disc is label side up. If so, load the disc label
side down.

The air is very humid. If so, wait about an hour and
try again.

The CD changer door is open. Completely close the
door to restore normal operation.

An empty magazine is inserted in the CD changer.
Try the magazine again with a disc loaded on one of
the trays.
If any error occurs repeatedly or if an error cannot be
corrected, please contact your dealer. If your radio
displays an error number, write it down and provide it to
your dealer when reporting the problem.Playing a Compact Disc

NOTICE:
Engine damage from running your engine
without coolant isn't covered by your warranty.
See ªOverheated Engine Protection Operating
Modeº in the Index.
NOTICE:
When adding coolant, it is important that you use
only DEX
-COOL
(silicate-free) coolant.
If coolant other than DEX-COOL is added to the
system, premature engine, heater core or
radiator corrosion may result. In addition, the
engine coolant will require change sooner
-- at
30,000 miles (50 000 km) or 24 months,
whichever occurs first. Damage caused by the use
of coolant other than DEX
-COOL
is not
covered by your new vehicle warranty.
If there seems to be no leak, with the engine on, check to
see if the electric engine cooling fans are running. If the
engine is overheating, both fans should be running. If
they aren't, your vehicle needs service.
How to Add Coolant to the Coolant
Recovery Tank
If you haven't found a problem yet, but the coolant level
isn't at the COLD mark, add a 50/50 mixture of clean,
drinkable water and DEX
-COOL
engine coolant at the
coolant recovery tank. (See ªEngine Coolantº in the
Index for more information.)
CAUTION:
Adding only plain water to your cooling system
can be dangerous. Plain water, or some other
liquid like alcohol, can boil before the proper
coolant mixture will. Your vehicle's coolant
warning system is set for the proper coolant
mixture. With plain water or the wrong mixture,
your engine could get too hot but you wouldn't
get the overheat warning. Your engine could
catch fire and you or others could be burned. Use
a 50/50 mixture of clean, drinkable water and
DEX
-COOL
coolant.

6-19 Engine Oil Additives
Don't add anything to your oil. Your dealer is ready to
advise if you think something should be added.
When to Change Engine Oil
Your vehicle has a computer that lets you know when to
change your engine oil. This is not based on mileage,
but on engine revolutions and engine operating
temperature. When the computer has calculated that the
oil needs changing, the Oil Life Monitor will indicate
that a change is necessary. The mileage between oil
changes will vary depending on how you drive your
vehicle
-- usually between 3,000 miles (5 000 km) and
7,500 miles (12 500 km) since your last oil change.
Under severe conditions, the indicator may come on
before 3,000 miles (5 000 km). Never drive your vehicle
more than 7,500 miles (12 500 km) or 12 months
(whichever occurs first) without an oil change.
The system won't detect dust in the oil. So, if you drive
in a dusty area, be sure to change your oil every
3,000 miles (5 000 km) or sooner. Remember to reset
the Oil Life Monitor whenever the oil is changed.How to Reset the Oil Life Monitor
To reset the Oil Life Monitor after the oil has been changed:
1. Press the MODE button until the light appears lit
next to OIL LIFE.
2. Press and hold the RESET button for three seconds.
The oil life percentage should change to 100%.
What to Do with Used Oil
Did you know that used engine oil contains certain
elements that may be unhealthy for your skin and could
even cause cancer? Don't let used oil stay on your skin
for very long. Clean your skin and nails with soap and
water, or a good hand cleaner. Wash or properly throw
away clothing or rags containing used engine oil. (See
the manufacturer's warnings about the use and disposal
of oil products.)
Used oil can be a real threat to the environment. If you
change your own oil, be sure to drain all free
-flowing oil
from the filter before disposal. Don't ever dispose of oil
by putting it in the trash, pouring it on the ground, into
sewers, or into streams or bodies of water. Instead,
recycle it by taking it to a place that collects used oil. If
you have a problem properly disposing of your used oil,
ask your dealer, a service station or a local recycling
center for help.
