CAUTION
The functions of ABS have certain
limitations. Good driving habits are the
basic guarantee for safe driving. Do not
drive carelessly just because the vehicle
is equipped with ABS.
To obtain the shortest possible braking
distance and braking stability, the brake
pedal should be depressed as hard as
possible.
When the ABS is faulty, the conventional
brake system of the vehicle can still work
normally, but the function of preventing
the wheels from being locked is
deactivated and the braking distance may
also be longer.
ABS fault warning lamp
If the ABS fault warning lamp comes on
during driving, it indicates that the ABS is faulty.
In this case, drive at a low speed to the nearest
authorized dealer for inspection.
Brake override system (BOS)
The BOS is used to first guarantee the braking
effect of the vehicle.
If the driver applies emergency braking with the
accelerator pedal suddenly stuck during driving,
the BOS will work, and the engine will only run at
a safe speed slightly higher than idle speed.
The BOS works only when all the following
conditions are met:
1. The engine speed is greater than 1200r/min;
2. The vehicle speed is greater than 10km/h;
3. The accelerator pedal is depressed, but
cannot be depressed sharply;
4. The accelerator pedal and the brake pedal are
depressed successively;
When the BOS is activated, the engine will
immediately return to idling condition and reduce
its power output.
The BOS is automatically deactivated if any of
the following conditions are met:
1. The accelerator pedal is released and then
depressed;
2. The accelerator pedal is depressed sharply;
3. The brake pedal is released.
