2005 Lexus RX 330 Owners Manual - Page 466

STARTING AND DRIVING You cannot set a desired speed if the master warning light comes on, the alarm sounds and the display indicates the warning code "E3". If this code appears on the display, see "(g) Conventional cruise control mode failure warning" on page 436. (c) Cancelling the preset speed You can cancel the preset speed by doing any of the following: a. Pulling the lever in the "CANCEL" direction. b. Depressing the brake pedal. c. Pressing the "ON−OFF" button. In the following cases, the preset speed automatically cancels out: a. The vehicle speed falls below about 40km/h (25 mph). b. If the vehicle speed drops 16 km/h (10 mph) below the preset speed, the preset speed will also automatically be cancelled. c. The slip indicator light blinks and an alarm sounds. (This occurs when the vehicle is about to skid.) If cancelled by a. or b., the preset speed data is cleared and you must set the speed from the beginning. If the preset speed automatically cancels out for other than the above reasons, do not operate the cruise control. Although it is no problem to continue driving, have your vehicle checked by your Lexus dealer at the earliest opportunity. (d) Resetting to a faster speed Push the lever up in the "+ RES" direction and hold it. Release the lever when the desired speed is attained. While the lever is held up, the vehicle will gradually gain speed. When the difference between the actual vehicle speed and the set speed is less than 5 km/h (3 mph), the set speed can be increased 1.6 km/h (1 mph) each time by pushing the lever up in the "+ RES" direction quickly within 0.6 seconds. However, a faster way to reset is to accelerate the vehicle and then push the lever down in the "− SET" direction. (e) Resetting to a slower speed Push the lever down in the "− SET" direction and hold it. Release the lever when the desired speed is attained. While the lever is held down, the vehicle speed will gradually decrease. When the difference between the actual vehicle speed and the set speed is less than 5 km/h (3 mph), the set speed can be lowered 1.6 km/h (1 mph) each time by pushing the lever down in the "− SET" direction quickly within 0.6 seconds. However, a faster way to reset is to accelerate the vehicle and then push the lever down in the "− SET" direction. 435
