Isuzu D-MAX 2020 Owner's And Driver's Manual page 447

This function generates greater braking force by increasing the force that the driver
applies to the brake pedal when braking suddenly, such as for emergency stops.
Also, this function activates when the autonomous emergency brake (AEB) activates
or when the brake is applied during the forward collision warning.
WARNING
• The brake assist function is not an automatic brake. This function operates when
braking suddenly, but it does not enable stopping under conditions exceeding
safe limits. Moreover, this function may not operate in some situations. Always
drive safely.
CAUTION
• When the rear differential lock is operating (models with rear differential lock),
the brake assist function does not operate.
• If the ESC warning light is on, the brake assist function does not operate.
NOTE
• When the brake assist function is operating, the following occurs, but this does
not indicate a failure. Continue depressing the brake pedal.
- Motor sound is heard.
- The brake pedal vibrates.
- The feeling of depressing the brake pedal changes.
• Releasing the brake pedal while brake assist is operating may cancel the brake
assist function.
• The feeling of depressing the brake pedal changes. For example, the brake
pedal may feel stiff or as though it is being pulled downward.
• If the brake pedal is depressed again after the brake assist function was
terminated, the brake can be applied normally.
