Function and Activation Conditions
Note: This feature was made available on a very limited number of vehicles and as of 2022 is no longer an option.
Attention assist is active at speeds above approximately 37 mph (60 km/h).
Attention assist assesses the driver's level of fatigue or lapses in concentration by taking the following into account:
-
driving characteristics, such as remaining in the lane and active steering
-
trip related details such as the length of the drive
-
use of turn signals
-
use of the engine brake switch
-
uncharacteristic changes in the accelerator pedal position
If attention assist detects typical indicators of fatigue or increasing lapses in concentration on the part of the driver a warning tone sounds and a caution window, shown in Fig. and Fig., appears on the driver display. If ALA has been deactivated, it is automatically reactivated.

If the driver doesn't take a break when prompted, the soonest attention assist can issue another warning is 15 minutes.
When the engine is turned off or the vehicle is stationary for some time, attention assist resets its detection sequence.
