FRONT INLET GRILLE
Basic Operating Tip!!:
• Always keep the front inlet grilles clear of obstructions (leaves, ice, snow ,
etc .) .
2-22

Downloaded from www.Manualslib.com manuals search engine • Always keep the area under the front seat clear for maximum rear seat airflow . .: ,
• For optimum driving comfort in. heating or air conditioning modes keep ", windows . closed. .
•
Clear snow and ice from the hood and air inlet in front of the windshield . This improves heater ahd defroster performance and lowers the chance of
fogging
on the inside of the windshield.
• During winter operation
run the blower on "High" for a few moments
before driving off. This helps clear the Intake ducts of snow and further
lessens the chance of fogging on the insiele of the windshield.
The following pages of this manual proviele more operating tips for getting
maximum heating
and cooling comfort. (AlsO s"" "Engine Exhaust Gas Caution (Carbon Monoxidej"at the beginning of "Starting and Operating ."
Section 2 oHhismanual.)
Lower Air Vents (Non Air Conditioned Vehicle)
Two control handles located beneath the steering colulTYl open (pull) and ciose
(full in) the
lower "ram" air vents . The amount of air discharged at these lower
outlets increases with vehicle speed. Maximum airflow can be obtained by
opening any of the side door windows slightly. If so equipped, the rear quarter SWing-out windows will optimize lower vent performance and provide maximum
airflow without opening a siele dIoor glass. In this condition, mimimum air
buffeting
and road noise is incurred .

Downloaded from www.Manualslib.com manuals search engine OTHER CONTROLS AND FEATURES
LIMITED-SLIP REAR AXLE
On vehicles that have it. the optional limited-slip rear axle can give added
traction on snow, ice, mud, sand, gravel, etc. Normally , the limited-slip axle
unit works like a standard axle. However, when either drive wheel meets a
slippery enough surface, and the opposite wheel is on a surface with greater traction, the ,limited-slip 'unit can continue to give driving force tathe wheel
having the greater traction,instead 01 merely spinning the wheel that has the
least traction .
Whether your
vehicle has an optional limited-slip rear axle or a standard axle, take care when speeding up or, whera shifting into a lower gear or lower gear
range , when either or both rear wheels are traveling over a slippery surface .
Sudden acceleration or engine braking action (due to shifting to a lower gear)
could cause one or both drive wheels to spinorskid and the rear 01 the vehicle to slide sideways on the crowned, ·surface of a road or in a turn. Normal skid correction and cautious driving are called for at these times.
COURTJ:SY LIGHT DELAY SYSTEM
