Driver Alert System
The Driver Alert System is designed to help a driver who may be becoming fatigued or whois inadvertently leaving the lane.
IntroductionThe Driver Alert System consists of two differ-ent functions that can be switched ontogether or separately.• Driver Alert Control (DAC)
, see Driver
Alert Control (DAC) – introduction (p. 222)
• Lane Departure Warning (LDW)
, see
Lane Departure Warning (LDW) – intro-duction (p. 227)
When one or both of the functions has been switched on, it is in standby mode and is acti-vated when the vehicle exceeds a speed of40 mph (65 km/h). The function deactivates if the vehicle's speed goes under 37 mph (60 km/h). Both functions use a camera that is depend- ent on the road/lane being clearly marked bypainted lines on each side.
WARNING
The Driver Alert System does not function in all situations and is designed to be asupplementary aid. It is not, however,intended to replace the driver’s attentionand judgement.
Driver Alert Control (DAC) – introduction
DAC is intended to alert the driver if his/her driving becomes erratic, such as if the driveris distracted or fatigued. DAC is designed to help detect a slowly changing driving pattern. It is primarilyintended to be used on main roads and is notmeant for use in city traffic.
A camera monitors the painted lines marking the lane in which the vehicle is traveling andcompares the direction of the road with thedriver’s movements of the steering wheel.The driver is alerted if the vehicle does notfollow the lane smoothly.
NOTE
The camera has certain limitations, see Adaptive Cruise Control – limitations(p. 193).
WARNING
• DAC is not intended to extend the duration of driving. Always plan breaksat regular intervals to help remain alert.
• A warning from DAC should not beignored. A driver may not be aware ofhow fatigued he/she has become.
• In certain cases, fatigue may not affectthe driver’s behavior. In situations ofthis type, no warning will be provided.Therefore, it is important to takebreaks at regular intervals, regardlessof whether or not DAC has given awarning.
