06 06.07 Downhill assist control system (four−wheel drive models) The light will come on when the ignition key is turned to "ON", and will go off after about a few seconds. The light may come on for 60 seconds after the ignition key is turned to "ON". It is normal if they go out after a while. Depressing the brake pedal repeatedly may turn on the light. It is normal if they go out after a few seconds. If the "VSC TRAC" waning light and slip indicator light come on while driving, the vehicle stability control system does not work. However, as normal braking operates when being applied, there is no problem to continue your driving. In the following cases, contact your Toyota dealer: The downhill assist control system is a system that assists the deceleration of the engine brake when you drive down a steep hill. When you are driving down a hill with the four−wheel drive control switch knob (full−time four−wheel drive models) or multi−mode control switch knob (multi−mode four−wheel drive models) in the "L4" position, push the "DAC" switch to limit the vehicle's acceleration. If the vehicle is traveling at a speed of 25 km/h (15 mph) or less, you can descend at a constant speed. TO ACTIVATE THE DOWNHILL ASSIST CONTROL SYSTEM 1. Full−time four−wheel drive models- Turn the four−wheel drive control switch knob to the "L4" position. The system will not operate if the four− wheel drive control switch knob is in the "H4" position. Multi−mode four−wheel drive models-Turn the multi−mode control switch knob to the "L4" position. The system will not operate if the multi− mode control switch knob is in the "H4" position. 2. In order to make full use of the engine brake, putting the transmission in "L" or "2" is recommended. The system will operate even if the transmission selector lever is in "D", "4", "3" or "N". However, when it is in "L" or "2" the engine brake can also be utilized enabling the system to operate more effectively. CAUTION Do not rely excessively on the downhill assist control system. It may not be able to maintain a low speed over road surfaces or off−road surfaces on which sliding can easily occur, such as extremely steep slopes or icy or muddy roads. D The warning light does not come on after the ignition key is turned to "ON". D The warning light remains on after the ignition key is turned to "ON".
