7-36 Starting and operating Cruise control Cruise control enables you to maintain a constant vehicle speed without holding your foot on the accelerator pedal and it is operative when the vehicle speed is 25 mph (40 km/h) or more. Make sure the main switch is turned "OFF" when the cruise control is not in use to avoid unintentionally setting the cruise control. NOTE On an uphill grade, when the clutch pedal is depressed while the brake pedal is also depressed, braking power is maintained temporarily by the Hill start assist system when the brake pedal is released. The driver is therefore able to start the vehicle the same way as on a level grade, just using the clutch and accelerator pedal. The Hill start assist system does not operate when the vehicle is facing downhill. And the Hill start assist system may not operate on slight grades. When starting in reverse and using the Hill start assist system, a braking effect may be felt even after the brake pedal has been released. However, this braking effect should disappear once the clutch pedal is released. A slight jolt may be felt when the vehicle begins to move forward after being reversed. If the braking power of the Hill start assist system is insufficient after the brake pedal is released, apply more braking power by pressing the brake pedal again. If you press the main switch button while turning the ignition switch "ON", the cruise control function is deactivated and the "CRUISE" indicator light flashes. To reactivate the cruise control function, turn the ignition switch back to the "Acc" or "LOCK" position, and then turn it again to the "ON" position. WARNING Do not use the cruise control under any of the following conditions. This may cause loss of vehicle control: . driving up or down a steep grade . driving on slippery or winding roads . driving in heavy traffic
