244 STARTING AND OPERATING • "3" Drive This range eliminates shifts into Overdrive. The transmission will operate normally in First, Second and Third while in this range. The "3" position should also be used when descending steep grades to prevent brake system distress. NOTE: Using the "3" range while operating the vehicle under heavy operating conditions will improve performance and extend transmission life by reducing excessive shifting and heat build up. • "L" Low This range should be used for engine braking when descending very steep grades. In this range, upshifts will occur only to prevent engine overspeed while downshifts occur earlier than other gear range selections. NOTE: The vehicle computer will over ride Overdrive and "3" Drive ranges by changing shift points if the transmission operating temperature exceeds acceptable limits. This is done to prevent transmission damage due to overheating. ALL WHEEL DRIVE - IF EQUIPPED This feature provides full time, on-demand, All Wheel Drive (AWD). The system is automatic with no driver inputs or additional driving skills required. Under normal driving conditions, the front wheels provide most of the traction. If the front wheels begin to lose traction, power is shifted automatically to the rear wheels. The greater the front wheel traction loss, the greater the power transfer to the rear wheels.
