Driving your vehicle WARNING • The Vehicle Stability Management system is not a substitute for safe driving practices but a supplementary function only. It is the responsibility of the driver to always check the speed and the distance to the vehicle ahead. Always hold the steering wheel firmly while driving. • Your vehicle is designed to activate according to the driver's intention, even with installed VSM. Always follow all the normal precautions for driving at safe speeds for the conditions - including driving inclement weather and on a slippery road. • Driving with varying tire or wheel sizes may cause the VSM system to malfunction. When replacing tires, make sure they are the same size as your original tires. Hill-start assist control (HAC) (if equipped) A vehicle has the tendency to slip back on a steep hill when the driver begins to accelerate after a stop. The Hill-start Assist Control (HAC) prevents the vehicle from slipping back by operating the brakes automatically for about 2 seconds. The brakes are released when the accelerator pedal is depressed or after about 2 seconds. WARNING The HAC is activated only for about 2 seconds, so always depress the accelerator pedal to begin accelerating after a stop. OLM059021L Downhill brake control (DBC) (if equipped) The Downhill Brake Control (DBC) helps the driver descend steep hills and is activated at speeds less then 22 mph. DBC defaults to the OFF position whenever the ignition is turned on. The DBC can be turned on or off by pushing the button. ✽ NOTICE • The HAC does not operate when the transaxle shift lever is in the P (Park) or N (Neutral) position. • The HAC activates even though the ESC is off but it does not activate when the ESC has malfunctioned. 5 33
