328 STARTING AND OPERATING
DRIVE
This range should be used for most city and highway
driving. It provides the best fuel economy. The DRIVE
position provides optimum driving characteristics under
all normal operating conditions.
When frequent transmission shifting occurs (such as
when operating the vehicle under heavy loading condi-
tions, in hilly terrain, traveling into strong head winds, or
while towing heavy trailers), use the AutoStick shift
control (if equipped) to select a lower gear ratio. Under
these conditions, using a lower gear ratio will improve
performance and extend transmission life by reducing
excessive shifting and heat buildup.
During sustained high speed driving or trailer towing up
long grades on hot days, the automatic transmission oil
may become too hot. If this happens, the transmission
overheat indicator light will come on, and the vehicle will
slow slightly until the transmission cools down enough
to allow a return to the requested speed. This is done to
prevent transmission damage due to overheating. If the
high speed is maintained, the overheating may reoccur,
as before, in a cyclic fashion.
LOW – IF EQUIPPED
This range should be used for engine braking when
descending very steep grades. In this range, the trans-
mission will downshift for maximum engine braking,
and upshifts will occur only to prevent engine overspeed.
