Overdrive Operation
The automatic transmission includes an electronically
controlled Overdrive (fifth and sixth gears). The trans-
mission will automatically shift into the Overdrive gear if
the following conditions are present:

• the shift lever is in the DRIVE position,
• the transmission fluid has reached an adequate tem-

perature,

• the engine coolant has reached an adequate tempera-

ture,

• vehicle speed is sufficiently high, and
• the TOW/HAUL switch has not been activated.

When To Use TOW/HAUL Mode
When driving in hilly areas, towing a trailer, carrying a
heavy load, etc., and frequent transmission shifting oc-
curs, press the TOW/HAUL switch to select TOW/

HAUL mode. This will improve performance and reduce
the potential for transmission overheating or failure due
to excessive shifting. When operating in TOW/HAUL
mode, transmission upshifts are delayed, and the trans-
mission will automatically downshift (for engine brak-
ing) during steady braking maneuvers.
