STARTING & DRIVING
When the emergency braking manoeuvre is exited, the
HAZ function will be switched off after a few seconds.
Note: As the vehicle speed drops to below 6 mph ( 10
km/h) and the brake lamps no longer flash, the hazard
warning lamps will illuminate automatically. Short
press the hazard warning lamp button or increase your
speed to above 12 mph ( 20 km/h) for more than 5
seconds to switch off the hazard warning lamps.
Multi-Collision Brake System ( MCB )
The MCB function will automatically apply the brake to
reduce the vehicle speed and improve the vehicle stability
after a collision. It is designed to reduce the risk of a
secondary collision caused by the uncontrolled movement
of the vehicle after a collision.
The MCB will be activated when the following conditions
are all met at the same time:
• A vehicle collision where seat belts or airbags are
deployed;
• The vehicle speed is less than 37.5 mph ( 60 km/h);
• The steering wheel has not been turned in excess of
180 °;
198
• SCS is fault free.
If the driver firmly presses the accelerator pedal after a
collision, the system will not be triggered.
If the driver firmly presses the accelerator pedal after the
MCB function is triggered, the system will exit the braking
state.
Note: The MCB function cannot guarantee that the
vehicle will slow down in all collision situations, as the
collision may cause some parts to malfunction or fail,
affecting the normal operation of the function.
