'05 TUNDRA_U (L/O 0504) Traction control system If the "4LO" (low speed four −wheel drive) indicator light flashes and the buzzer sounds when you push the "2WD/4HI" switch, this reminds you that the transfer mode is not in "2WD" mode.

Drive straight ahead while accelerating or decelerating, or drive forward or backward in a short distance. The traction control system automatically helps prevent the spinning of rear wheels (two−wheel drive models) or 4 wheels (four −wheel drive models) 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 to the rear wheels (two−wheel drive models) or 4 wheels (four−wheel drive models) 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. Without tachometer With tachometer 191 2005 TUNDRA from Apr. '05 Prod. (OM34440U)
