STARTING AND DRIVING The Lexus park assist system may not detect the following: D Thin objects such as wire or rope D Objects with a surface area too small to reflect ultrasonic waves such as wire gauze or fence D Sound wave absorbing objects such as cotton or snow D Objects with a sharp edge D Shorter objects D Tall objects with the upper part projected For vehicles with a Navigation System, the park assist graphics appear both on the navigation display and multi−information display. For details, see the separate "Navigation System Owner's Manual". For vehicles sold in Canada This ISM device complies with Canadian ICES−001. CRUISE CONTROL The cruise control allows you to cruise the vehicle at a desired speed over about 40 km/h (25 mph) with your foot off the accelerator pedal. Your cruising speed can be maintained although a slight speed change may occur when driving up or down a gradient, within the limits of engine performance. On steeper hills, a great speed change will occur so it is better to drive without the cruise control. When the cruise control is on, the driving pattern of the automatic transmission is fixed in the normal position, regardless of the position of the selector switch. CAUTION D To help maintain maximum control of your vehicle, do not use the cruise control when driving in heavy or varying traffic, or on slippery (rainy, icy or snow−covered) or winding roads. D Avoid vehicle speed increases when driving downhill. If the vehicle speed is too fast in relation to the cruise control set speed, cancel the cruise control then downshift the transmission to use engine braking to slow down. 249
