WARNING!

Do not downshift for additional engine braking on a
slippery surface. The drive wheels could lose their
grip and the vehicle could skid, causing an accident
or personal injury.

NOTE:

To select the proper gear position for maximum

deceleration (engine braking), simply press and hold the
ERS (-) switch down. The transmission will shift to the
range from which the vehicle can best be slowed down.

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.
