(f) Good driving practice D If the transmission repeatedly upshifts and downshifts between the third and overdrive gears when climbing a gentle slope, turn off the overdrive switch. Be sure to turn the switch on immediately after climbing the slope. D When towing a trailer, in order to maintain efficient engine braking and electrical charging performance, do not use overdrive. CAUTION Always keep your foot on the brake pedal while stopped with the engine running. This prevents the vehicle from creeping. NOTICE Do not hold the vehicle on an upgrade with the accelerator pedal. This can cause the transmission to overheat. Always use the brake pedal or parking brake. (g) Rocking your vehicle if stuck CAUTION If your vehicle becomes stuck in snow, mud, sand, etc., then you may attempt to rock the vehicle free by moving it forward and backward. Do not attempt this procedure if people or objects are anywhere near the vehicle. During the rocking operation the vehicle may suddenly move forward or back as it becomes un-stuck, causing injury or damage to nearby people or objects.
