*2:Display occasionally changes On/Off for a moment after ignition switch is turned ON. This is operation for
checking purposes and is not a malfunction.

for ON/OFF con-

ditions of each warning lamp and indicator lamp.
*4: CVT models
*5: “DDS” means “hill descent control” or “downhill drive support”.

VDC FUNCTION, TCS FUNCTION, BRAKE LIMITED SLIP DIFFERENTIAL (BLSD) FUNCTION,
BRAKE ASSIST FUNCTION, BRAKE FORCE DISTRIBUTION FUNCTION, hill start assist FUNC-
TION AND ADVANCED hill descent control FUNCTION (4WD MODELS WITH GASOLINE ENGINE)

VDC warning lamp in combination meter turn ON when a malfunction occurs in system [ABS actuator and
electric unit (control unit)]. The control is suspended for VDC function, TCS function, brake limited slip differen-
tial (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 chas-
sis 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) func-
tion, brake assist function, brake force distribution function, hill start assist function, advanced hill descent con-
trol 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.

ABS FUNCTION

ABS warning lamp and VDC warning lamp in combination meter turn ON when a malfunction occurs in system
[ABS actuator and electric unit (control unit)]. The control is suspended for VDC function, TCS function, ABS
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, ABS
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). However, EBD function is operated normally.
NOTE:
ABS self-diagnosis sound may be heard the same as in the normal condition, because self-diagnosis is per-
formed when ignition switch turns ON and when vehicle initially starts.

EBD FUNCTION

ABS warning lamp, brake warning lamp and VDC warning lamp in combination meter turn ON when a mal-
function occurs in system [ABS actuator and electric unit (control unit)]. The control is suspended for VDC
function, TCS function, ABS function, EBD 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, ABS function, EBD 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).
