BRAKE ASSIST FUNCTION
BRAKE ASSIST FUNCTION : System Description
INFOID:0000000010723639
• When the driver brakes hard in an emergency, the stopping distance is reduced by increasing brake fluid
pressure.
• Fail-safe function is adopted. When a malfunction occurs in brake assist function, the control is suspended
for VDC function, TCS function, brake limited slip differential (BLSD) function, brake assist function, brake
force distribution function, hill start assist function, advanced hill descent control function (4WD models with
gasoline engine), active trace control function (control of chassis control module) and active ride control
function (control of chassis control module). The vehicle status becomes the same as models without VDC
function, TCS function, brake limited slip differential (BLSD) function, brake assist function, brake force dis-
tribution function, hill start assist function, advanced hill descent control function (4WD models with gasoline
engine), active trace control function (control of chassis control module) and active ride control function (con-
trol of chassis control module). However, ABS function and EBD function are operated normally. Refer to

BRAKE FORCE DISTRIBUTION FUNCTION
BRAKE FORCE DISTRIBUTION FUNCTION : System Description
INFOID:0000000010723640
• Brake force distribution function helps provide a more stable and
secure feeling.
• During cornering, when brake operation is performed brake fluid
pressure of each wheel is controlled based on steering operation
amount by the driver and vehicle cornering status amount detected
by each sensor.
• Fail-safe function is adopted. When a malfunction occurs in brake
force distribution function, the control is suspended for VDC func-
tion, TCS function, brake limited slip differential (BLSD) function,
brake assist function, brake force distribution function, hill start
assist function, advanced hill descent control function (4WD mod-
els with gasoline engine), active trace control function (control of
chassis control module) and active ride control function (control of
chassis control module). The vehicle status becomes the same as
models without VDC function, TCS function, brake limited slip differential (BLSD) function, brake assist func-
tion, brake force distribution function, hill start assist function, advanced hill descent control function (4WD
models with gasoline engine), active trace control function (control of chassis control module) and active ride
control function (control of chassis control module). However ABS function and EBD function are operated
normally. Refer to
NOTE:
Brake force distribution function may not always be operates in all driving conditions.
