04 SIENNA_U (L/O 0408) Traction control system (two −wheel drive models) CAUTION Never attempt to move the selector lever into "P" position under any circumstances while the vehicle is moving. Serious mechanical damage and loss of vehicle control may result. (g) Good driving practice NOTICE Always use the brake pedal or the 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. (h) If you cannot shift the selector lever out of "P" position If you cannot shift the selector lever from the "P" position 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 429 in Section 4. The traction control system automatically helps prevent the spinning of front wheels when the vehicle is started or accelerated on slippery road surfaces. When the ignition key is turned to "ON", the system automatically turns on. CAUTION Under certain slippery road conditions, full traction of the vehicle and power against front wheels cannot be maintained, even though the traction control system is in operation. Do not drive the vehicle under any speed or maneuvering conditions which may cause the vehicle to lose traction control. In situations where the road surface is covered with ice or snow, your vehicle should be fitted with snow tires or tire chains. Always drive at an appropriate and cautious speed for the present road conditions. D If the transmission repeatedly shifts up and down between fourth gear and overdrive when climbing a gentle slope, shift the selector lever to the "4" position. Be sure to shift the selector lever to the "D" position immediately afterward. D When towing a trailer, in order to maintain engine braking efficiency, do not use "D" position. CAUTION Always keep your foot on the brake pedal while stopped with the engine running. This prevents the vehicle from creeping. 182 2004 SIENNA from Aug. '04 Prod. (OM45422U)
