The rear temperature knob and the rear blower speed can
be adjusted as desired by the second seat occupants.
Automatic Temperature Control — If Equipped
The Infrared Three-Zone Automatic Temperature Control
System automatically maintains the interior comfort level
desired by the driver and all passengers. This is accom-
plished by using two infrared sensors, located in the
center of the instrument panel. The two infrared sensors
independently measure the surface temperature of the
driver and passenger. Based on the sensor input, the
system automatically adjusts the air temperature, the air
flow volume, and amount of outside air recirculation.
This maintains a comfortable temperature even under
changing conditions. Operation of the system is quite simple. Begin by press-
ing the auto rocker switch to the “HI” or “LO” position,
the word “AUTO” will illuminate in the front ATC
display along with “HI” or “LO”. The system will then
automatically regulate the amount of air flow. Next, dial
in the temperature you would like the system to maintain
by pressing the driver’s or passenger’s temperature con-
trol button. The rear temperature can only be adjusted
from the front when the “REAR SYSTEM” knob on the Three-Zone Automatic Temperature Control UNDERSTANDING YOUR INSTRUMENT PANEL 289

these outlets can be individually adjusted to direct
the flow of air. Moving the air vane knob on the outlets to
one side will shut off the air flow.

result.
Limited Use Spare — If Equipped
The limited use spare tire is for temporary emergency use
on your vehicle. This tire is identified by a limited use
spare tire warning label located on the limited use spare
tire and wheel assembly. This tire may look like the
original equipped tire on the front or rear axle of your
vehicle, but it is not. Installation of this limited use spare
tire affects vehicle handling. Since it is not the same tire,
replace (or repair) the original tire and reinstall on the
vehicle at the first opportunity. WARNING!The limited use spare tires are for emergency use
only. Installation of this limited use spare tire affects
vehicle handling. With this tire, do not drive more
than 60 mph (100 km/h). Keep inflated to the cold
tire inflation pressure listed on either your tire
placard or limited use spare tire and wheel assembly.
Replace (or repair) the original tire at the first
opportunity and reinstall it on your vehicle. Failure
to do so could result in loss of vehicle control.

Synthetic Engine Oils
There are a number of engine oils being promoted as
either synthetic or semi-synthetic. If you chose to use
such a product, use only those oils that are American
Petroleum Institute (API) Certified and have the recom-
mended SAE viscosity grade. Follow the maintenance
schedule that describes your driving type.
Materials Added to Engine Oil
The manufacture strongly recommends against the addi-
tion of any additives (other than leak detection dyes) to
the engine oil. Engine oil is an engineered product and
it’s performance may be impaired by supplemental ad-
ditives.
Disposing of Used Engine Oil And Oil Filters
Care should be taken in disposing of used engine oil and
oil filters from your vehicle. Used oil and oil filters,
indiscriminately discarded, can present a problem to the
environment. Contact your dealer, service station, or governmental agency for advice on how and where used
oil and oil filters can be safely discarded in your area.
Engine Oil Filter
The engine oil filter should be replaced at every engine
oil change.
Engine Oil Filter Selection
All the manufacturers engines have a full-flow type oil
filter. Use a filter of this type for replacement. The quality
of replacement filters varies considerably. Only high
quality filters should be used to assure most efficient
service. Mopar Engine Oil Filters are a high quality oil
filter and are recommended.
Drive Belts — Check Condition and Tension
At the mileage indicated in the maintenance schedule, all
belts should be checked for condition and proper tension.
Improper belt tension can cause belt slippage and failure. MAINTAINING YOUR VEHICLE 423
