226 STARTING AND OPERATING
DRIVE
This range should be used for most city and highway
driving. It provides the smoothest upshifts and down-
shifts and the best fuel economy.
The transmission automatically upshifts through 5th
gear. The DRIVE position provides optimum driving
characteristics under all normal operating conditions.
When frequent transmission shifting occurs when using
the Overdrive range, such as when operating the vehicle
under heavy loading conditions (in hilly terrain, travel-
ing into strong head winds, or while towing heavy
trailers, use the AutoStick
range.
Delayed Shifts in Cold Temperatures
During cold temperature operation, you may notice
delayed upshifts depending on engine and transmission
mode and select the "3"
temperature as well as vehicle speed. This feature im-
proves warm up time of the engine and transmission to
achieve maximum efficiency.
Temporary Transmission Limp Home Mode
The transmission is monitored for abnormal conditions.
If a condition is detected that could result in transmission
damage, the transmission will engage Limp Home Mode.
If vehicle acceleration worsens or the transmission no
longer shifts, the transmission is most likely operating in
the Limp Home Mode. In this mode, the transmission
will remain in the current gear until the vehicle is
brought to a stop. After the vehicle has stopped, PARK,
REVERSE, and NEUTRAL will continue to operate. Sec-
ond gear will operate in the DRIVE position. The Mal-
function Indicator Light (MIL) may be illuminated.
