08 SIENNA_U (L/O 0801) -Conventional (fixed speed) cruise control mode If "E3" appears on the display, a system malfunction has been detected. If this code appears, stop your vehicle in a safe place, turn the engine switch off, and then restart it to reset the system. If the setting still cannot be made or the same code appears again, the system might have malfunctioned. Although there is no problem to continue driving, contact your Toyota dealer. The conventional cruise control mode is designed to maintain a set cruising speed without requiring the driver to operate the accelerator. Cruising speed can be set to any speed above 45 km/h (28 mph). Within the limits of the engine's capabilities, cruising speed can be maintained up or down grades. However, changes in vehicle speed may occur on steeper grades. D Do not use the conventional mode in the following conditions, or serious injury or death could result: To help maintain maximum control of your vehicle, do not use conventional cruise control mode when using dynamic laser cruise control while driving in heavy or varying traffic, or on slippery (rainy, icy or snow−covered) or winding roads. Be careful about vehicle speed as it may increase when driving downhill with the conventional cruise control mode selected. CAUTION D In the conventional cruise control mode, the approach warning does not activate and no alarm will sound even if you are too close to the vehicle ahead, as neither the presence of the vehicle ahead nor the vehicle−to−vehicle distance is detected. Pay special attention to the distance between your vehicle and the vehicle ahead. Always confirm the setting in the display. 237 2008 SIENNA from Aug. '08 Prod. (OM45455U)
