reduce the potential for transmission overheating or
failure due to excessive shifting. When operating in
“TOW HAUL” mode, 6th gear (if equipped) is disabled
and 2-3 and 3-4 and 4–5 shift patterns are modified. Shifts
into Overdrive (5th gear) are allowed during steady
cruise (for improved fuel economy). Pressing the “TOW
HAUL O/D OFF” button a second time to select O/D
OFF will disable 5th and 6th gear completely, which
should eliminate any excessive transmission shifting.
The “TOW HAUL” or “O/D OFF” light will illuminate in
the instrument cluster to indicate when the switch has
been activated. Pressing the switch a third time restores
normal operation. If the “TOW HAUL” or “O/D OFF”
modes are desired, the button must be pressed each time
the engine is started.
WARNING!
Do not use the Tow/Haul feature when driving in icy
or slippery conditions as the increased engine brak-
ing can cause the rear wheels to slide and the vehicle
to swing around with the possible loss of vehicle
control, which may cause an accident possibly result-
ing in personal injury or death.
When To Lock Out Overdrive
When driving in hilly areas, towing a trailer, carrying a
heavy load, etc., and frequent 6–5–6 or 5–4–5 transmis-
sion shifting occurs, press the “TOW/HAUL” button.
This will improve performance and reduce the potential
for transmission overheating or failure due to excessive
shifting.
