BRAKE ASSIST FUNCTION : System Description
INFOID:0000000011280576
• 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, hill start
assist function and Brake force distribution function. The vehicle status becomes the same as models with-
out VDC function, TCS function, Brake limited slip differential (BLSD) function, Brake assist function, hill
start assist function and Brake force distribution function. However, ABS function and EBD function are oper-
ated normally. Refer to

hill descent control (Downhill Drive Support) FUNCTION : System Description
INFOID:0000000011280578
• The hill descent control system will help maintain vehicle speed when driving on steeper downhill grades.
Hill descent control will provide braking allowing the driver to concentrate on steering while reducing the bur-
den of brake and accelerator operation.
• To operate the system, push the hill descent control switch. the hill descent control indicator in the combina-
tion meter will turn on
• Hill start assist function is only for the start aid. It maintains the brake fluid pressure for approx. 2 seconds
after releasing the brake pedal, and then decreases the pressure gradually. If the vehicle starts by the accel-
erator operation, the brake is released automatically and a smooth start can be performed.
• Fail-safe function is adopted. When a malfunction occurs in hill start assist function, the control is suspended
for VDC function, TCS function, hill start assist function, Brake force distribution function and Active trace
control function. The vehicle status becomes the same as models without VDC function, TCS function, hill
start assist function, Brake force distribution function and Active trace control function. However, ABS func-
tion and EBD function are operated normally. Refer to

hill start assist FUNCTION
hill start assist FUNCTION : System Description
INFOID:0000000011280579
• This function maintains brake fluid pressure so that the vehicle does not move backwards even if brake
pedal is released to depress accelerator pedal to start the vehicle while it is stopped on an uphill slope by
depressing brake pedal.
• This function operates when the vehicle is in stop status on a uphill slope of slope ratio 10% or more and
selector lever is in the position other than P or N.
• hill start assist function is only for the start aid. It maintains the brake fluid pressure for approx. 2 seconds
after releasing the brake pedal, and then decreases the pressure gradually. If the vehicle can start by the
accelerator operation, the brake is released automatically and a smooth start can be performed.
• Fail-safe function is adopted. When a malfunction occurs in hill start assist function, the control is suspended
for VDC function, TCS function, Brake limited slip differential (BLSD) function, Brake assist function, hill start
assist function and Brake force distribution function. The vehicle status becomes the same as models with-
