STARTING AND DRIVING (f) Good driving practice D If the transmission repeatedly shifts up and down between the fourth and overdrive gears when climbing a gentle slope, shift the selector lever to the "4" position. Be sure to shift the selector lever to the "D" position after climbing the slope. D When towing a trailer, in order to maintain efficient engine braking and electrical charging performance, do not use overdrive. (g) If you cannot shift the selector lever If you cannot shift the selector lever even though the brake pedal is depressed, use the shift lock override button. For instructions, see "If you cannot shift automatic transmission selector lever" on page 453. (h) Driving in second start mode CAUTION Always keep your foot on the brake pedal while stopped with the engine running. This prevents the vehicle from creeping. NOTICE Always use the brake pedal or parking brake to hold the vehicle on an upgrade. Do not attempt to hold the vehicle using the accelerator pedal, as this can cause the transmission to overheat. In the second start mode, the transmission system shifts up from second gear. Use this mode when starting your vehicle in sand, mud, ice or snow. To set the second start mode, push the "2nd STRT" switch. In the second start mode, the "2nd STRT" indicator light comes on. To cancel the second start mode, push the "2nd STRT" switch once again. 355
