Isuzu D-MAX 2020 Owner's And Driver's Manual page 449

The hill start assist works to assist the driver by lessening the vehicle roll-back that
occurs when the vehicle pulls away on steep slopes. When the driver's foot is moved
from the brake pedal to the accelerator pedal, the brakes are held in place for a
maximum of approximately 2 seconds.
The hill start assist will operate when all the following conditions are met:
• When the vehicle pulls away in the forward or reverse directions on a slope
• When the vehicle is stopped with the brake pedal firmly depressed
• When the parking brake is released
WARNING
• The hill start assist is not for stopping the vehicle on slopes. The vehicle may
start moving if the pressure applied to the brake pedal is decreased when the
vehicle is stopped on a slope, even if the system is operating normally. Because
of this, it is necessary to continue to firmly depress the brake pedal when the
vehicle is stopped.
• Do not overestimate the effectiveness of the hill start assist. Doing so may result
in sudden vehicle movement when pulling away, possibly leading to an accident.
Pull away only after checking the vehicle's surroundings and with the proper
procedure.
• Pull away immediately after removing your foot from the brake pedal. If the
vehicle were to begin rolling back due to inertia on slopes, etc., the engine may
stall, brake effectiveness will decrease, and the steering wheel will become
heavy, possibly leading to an accident.
CAUTION
• When the rear differential lock is operating (models with rear differential lock),
the hill start assist does not operate.
• The hill start assist may not operate when the ESC warning light comes on. Be
especially careful if the ESC warning light is on when pulling away.
• The vehicle may roll-back due to the vehicle load when driving on extremely
sharp slopes or poor road surfaces (such as those that are icy or muddy).
• The hill start assist may not operate if the brake pedal is not sufficiently
depressed when the vehicle is stopped, or depending on the number of
passengers or cargo weight.
• The hill start assist cannot lessen vehicle roll-back for more than 2 seconds.
