264 STARTING AND OPERATING
If the vehicle has not been driven for several days, the first
few seconds of operation after shifting the transmission
into gear may seem sluggish. This is due to the fluid
partially draining from the torque converter into the trans-
mission. This condition is normal and will not cause
damage to the transmission. The torque converter will
refill within five seconds after starting the engine.
When To Use TOW/HAUL Mode
When driving in hilly areas, towing a trailer, carrying a
heavy load, etc., and frequent transmission shifting occurs,
push the TOW/HAUL switch to activate TOW/HAUL
mode. This will improve performance and reduce the poten-
tial for transmission overheating or failure due to excessive
shifting. When operating in TOW/HAUL mode, transmis-
sion upshifts are delayed, and the transmission will automat-
ically downshift (for engine braking) when the throttle is
closed and/or during steady braking maneuvers.
TOW/HAUL Switch
The TOW/HAUL Indicator Light” will illuminate in the
instrument cluster to indicate that TOW/HAUL mode has
been activated. Pushing the switch a second time restores
normal operation. Normal operation is always the default at
engine start-up. If TOW/HAUL mode is desired, the switch
must be pushed each time the engine is started.
