This range is to be used when engine braking stronger than that of the "3" range position is necessary. Maximum allowable speeds To get on a highway or to pass slower traffic, maximum acceleration may be necessary. Make sure you observe the following maximum allowable speeds in each range: 5.7 L V8 (3UR−FE) engine Without towing package range 1 2 3 With towing package range 1 2 3 km/h 59 101 147 (mph) (36) (62) (91) km/h 62 106 154 (mph) (38) (65) (95) Four −wheel drive models package range 1 2 3 4 5 6 km/h 22 38 56 64 64 64 with towing -Front drive control switch knob at "4L" (mph) (13) (23) (34) (39) (39) (39) D "1" (First range): The gear is fixed in first regardless of vehicle speed and driving conditions. This range is to be used when maximum engine braking is necessary. If you attempt to downshift the transmission when it is not possible to downshift due to high vehicle speed, a warning tone sounds twice. NOTICE Do not downshift if you are going faster than the maximum allowable speed for the next lower range. When the "S" mode indicator light does not come on even with the selector lever moved to the "S" position, there may be a problem somewhere in the system. Have your vehicle checked/repaired by your Toyota dealer as soon as possible. In this case, you can drive in the same condition as in the "D" position.
