282 STARTING AND OPERATING • vehicle speed is above approximately 30 mph (48 km/h); • the TOW/HAUL switch has not been activated; • transmission temperature. has reached normal operating transmission may downshift out of OVERDRIVE until the transmission cools down. After cooldown, the transmission will resume normal operation. The transmission will downshift from OVERDRIVE to DRIVE if the accelerator pedal is fully depressed at vehicle speeds above approximately 35 mph (56 km/h). When To Use TOW/HAUL Mode When driving in hilly areas, towing a trailer, carrying a heavy load, etc., and frequent transmission shifting occurs, press the TOW/HAUL button. This will improve performance and reduce the potential for transmission overheating or failure due to excessive shifting. When operating in TOW/HAUL mode, 5th gear (if equipped) is disabled and 2-3 and 3-4 shift patterns are modified. Shifts into OVERDRIVE (4th gear) are allowed during steady cruise (for improved fuel economy) and automatic closed-throttle downshifts to 3rd gear (for improved braking) will occur during steady braking. NOTE: If the vehicle is started in extremely cold temperatures, the transmission may not shift into OVERDRIVE and will automatically select the most desirable gear for operation at this temperature. Normal operation will resume when the transmission fluid temperature has risen to a suitable level. Refer also to the Note under torque converter clutch, later in this section. If the transmission temperature gets extremely hot, the transmission will automatically select the most desirable gear for operation at this temperature. If the transmission temperature becomes hot enough, the "Transmission Temperature Indicator Light" may illuminate and the
