Hill start Assist Control is a convenience function. The main intent is to prevent the vehicle from rolling backwards while taking off uphill from a stop. HAC holds the braking pressure built up by the driver during stopping for 2 seconds after releasing the brake pedal.
During the pressure-hold period, the driver has enough time to press the accelerator pedal to drive off.
The braking pressure is reduced as soon as the system detects the driver's intention to drive off.
WARNING
The HAC is usually activated only for 2 seconds: If the built-up brake hold pressure is insufficient to hold the vehicle, the driver must quickly activate the brake pedal to prevent the vehicle from rolling backward. Unexpectedly rolling backward could cause an accident, and serious injury.
NOTICE
Checking the brake/clutch fluid level
Check the fluid level in the reservoir periodically. The fluid level should be
between MAX and MIN marks on the side of the reservoir.
Before removing the reservoir cap and adding brake/clutch fl ...
