CD/DVD MAINTENANCE
To keep a CD/DVD in good condition, take the following
precautions:
1. Handle the disc by its edge; avoid touching the
surface.
2. If the disc is stained, clean the surface with a soft cloth,
wiping from center to edge.
3. Do not apply paper or tape to the disc; avoid scratch-
ing the disc.
4. Do not use solvents such as benzene, thinner, cleaners,
or antistatic sprays.5. Store the disc in its case after playing.
6. Do not expose the disc to direct sunlight.
7. Do not store the disc where temperatures may become
too high.
NOTE:
If you experience difficulty in playing a particu-
lar disc, it may be damaged (i.e. scratched, reflective
coating removed, a hair, moisture or dew on the disc)
oversized, or have theft protection encoding. Try a
known good disc before considering disc player service.
RADIO OPERATION AND CELLULAR PHONES
Under certain conditions, the operation of a cellular
phone in your vehicle can cause erratic or noisy perfor-
mance from your radio. This condition may be lessened
or eliminated by relocating the cellular phone antenna.
This condition is not harmful to the radio. If your radio
performance does not satisfactorily “clear” by the repo-
sitioning of the antenna, it is recommended that the radio
volume be turned down or off during cellular phone
operation.

smoke, perfumes, etc.) from sticking to the windows.
Contaminates increase the rate of window fogging.
Summer Operation
Air conditioned vehicles must be protected with a high
quality antifreeze coolant during summer to provide
proper corrosion protection and to raise the boiling point
of the coolant for protection against overheating. A 50 %
concentration is recommended. Refer to ”Engine Cool-
ant” under “ Fluids, Lubricants and Genuine Parts” in
section 7.
When using the air conditioner in extremely heavy traffic
in hot weather, especially when towing a trailer, addi-
tional engine cooling may be required. If this situation is
encountered, operate the transmission in a lower gear to
increase engine RPM, coolant flow and fan speed. When
stopped in heavy traffic, it may be necessary to shift into
NEUTRAL and depress the accelerator slightly for fast
idle operation to increase coolant flow and fan speed.Your air conditioning system is also equipped with an
automatic recirculation system. When the system senses
a heavy load or high heat conditions, it may use partial
Recirculation A/C mode to provide additional comfort.
Winter Operation
When operating the system during the winter months,
make sure the air intake, located directly in front of the
windshield, is free of ice, slush, snow, or other
obstructions.

NOTE:Use caution when operating a heavily loaded
vehicle in SECOND or FIRST gear selections in high
ambients as torque converter slip can impose significant
additional heat load on the cooling system.
Overdrive Operation
The overdrive automatic transmission contains an elec-
tronically controlled fourth and fifth (if equipped) speed
(Overdrive). The transmission will automatically shift
from DRIVE to Overdrive if the following conditions are
present:
•the shift lever is in DRIVE;
•the engine coolant has reached normal operating tem-
perature;
•vehicle speed is above approximately 30 mph
(48 km/h);
•the “TOW HAUL O/D OFF” switch has not been
activated;
•transmission has reached normal operating
temperature.
NOTE: If the vehicle is started in extremely cold tem-
peratures, the transmission may not shift into Overdrive
and will automatically select the most desirable gear for
operation at this temperature. Normal operation will
resume when the transmission fluid temperature has
risen to a suitable level. Refer to the “Note” under
“Torque Converter Clutch” in this section.
If the transmission temperature gets extremely hot, the
transmission will automatically select the most desirable
gear for operation at this temperature. If the transmission
temperature becomes hot enough the TRANS TEMP light
may illuminate and the transmission may downshift out
of Overdrive until the transmission cools down. After
cooldown, the transmission will resume normal opera-
tion.

economy) and automatic closed-throttle downshifts to
3rd gear are performed (for improved braking) when
driving conditions warrant. Pressing the “TOW HAUL
O/D OFF” button a second time to select O/D OFF will
disable 4th and 5th gear completely, which should elimi-
nate any excessive transmission shifting.
The “TOW HAUL” or “O/D OFF” light will illuminate in
the instrument cluster to indicate when the switch has
been activated. Pressing the switch a third time restores
normal operation. If the “TOW HAUL” or “O/D OFF”
modes are desired, the button must be pressed each time
the engine is started.
Torque Converter Clutch
A feature, designed to improve fuel economy, has been
included in the automatic transmission on your vehicle.
A clutch within the torque converter engages automati-
cally at calibrated speeds. This may result in a slightly
different feeling or response during normal operation inthe upper gears. When the vehicle speed drops or during
acceleration when the transmission downshifts to second
gear, the clutch automatically disengages.
NOTE:
•The torque converter clutch will not engage until the
transmission fluid and engine coolant are warm [usu-
ally after 1-3 miles (1.6 - 4.8 km) of driving]. Because
the engine speed is higher when the torque converter
clutch is not engaged, it may seem as if the transmis-
sion is not shifting into Overdrive when cold. This is
normal. Pressing the “TOW HAUL O/D OFF” button,
when the transmission is sufficiently warm, will dem-
onstrate that the transmission is able to shift into and
out of overdrive.
•If the vehicle has not been driven in several days, the
first few seconds of operation after shifting the trans-
mission into gear may seem sluggish. This is due to the
fluid partially draining from the torque converter into
