Precaution for Brake System

INFOID:0000000010723620

WARNING:

Since dust covering the front and rear brakes has an affect on human body, the dust must be removed
with a dust collector. Never splatter the dust with an air blow gun.
• Brake fluid use refer to 

MA-23, "Fluids and Lubricants"

.

• Never reuse drained brake fluid.
• Never spill or splash brake fluid on painted surfaces. Brake fluid may seriously damage paint. Wipe it off

immediately and wash with water if it gets on a painted surface.

• Always confirm the specified tightening torque when installing the brake pipes.
• After pressing the brake pedal more deeply or harder than normal driving, such as air bleeding, check each

item of brake pedal. Adjust brake pedal if it is outside the standard value.

• Never use mineral oils such as gasoline or light oil to clean. They may damage rubber parts and cause

improper operation.

• Always loosen the brake tube flare nut with a flare nut wrench.
• Tighten flare nut of brake tube to the specified torque using a flare

nut torque wrench (A).

• Turn the ignition switch OFF and disconnect the ABS actuator and

electric unit (control unit) harness connector or the battery negative
terminal before performing the work. Refer to 

BRC-9, "Precautions

for Removing Battery Terminal"

.

• Check that no brake fluid leakage is present after replacing the

parts.

Precaution for Brake Control System

INFOID:0000000010723621

• Always perform a pre-driving check to drive the vehicle.
• Always check speed and safety while driving the vehicle.
• To operate CONSULT while driving, more than one person is required to be in the vehicle to avoid interfer-

ence to driving and ensure safety.

• Slight vibrations are felt on the brake pedal and the operation noises occur, when VDC function, TCS func-

tion, 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) or active ride control func-
tion (control of chassis control module) operates. This is not a malfunction because it is caused by 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 func-
tion (4WD models with gasoline engine), active trace control function (control of chassis control module) or
active ride control function (control of chassis control module) that is normally operated.

• When starting engine or when starting vehicle just after starting engine, brake pedal may vibrate or motor

operating noise may be heard from engine compartment. This is normal condition.

• Brake stopping distance may become longer than models without ABS function depending on the road con-

ditions, when ABS function is operated on slippery road like rough road, gravel road or snowy road.

• When a malfunction is indicated, always collect information from the customer about conditions of occur-

rence, estimate cause, and perform operation. Check brake booster operation, brake fluid level, and brake
fluid leakage, as well as electrical system.

• The optimum performance is achieved by control for VDC function, TCS function, ABS function, EBD func-

tion, 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), when all of brakes, suspensions and tires installed on the vehicle are the specified size and parts.
Brake performance and controllability may be negatively affected when other parts than the specified are
installed.

• Brake stopping distance may become longer and steering stability may be negatively affected, when tires in

different size and combination or other parts than the specified are used.

[WITH VDC (ESP)]

PRECAUTIONS

• When a radio (including wiring), antenna and antenna lead line are located near ABS actuator and electric

unit (control unit), a malfunction or improper operation may occur for the control of VDC function, TCS func-
tion, 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).

• When the following items are replaced by other parts than genuine parts or modified, ABS warning lamp,

brake warning lamp and VDC warning lamp may turn ON, and the control may not operate normally 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 func-
tion (4WD models with gasoline engine), active trace control function (control of chassis control module) and
active ride control function (control of chassis control module).

- Suspension component parts (shock absorber, spring, bushing and others)
- Tire and wheel (other than the specified size)
- Brake component parts (brake pad, disc rotor, brake caliper and others)
- Engine component parts (ECM, muffler and others)
- Body reinforcement component parts (rollover bar, tower bar and others)
• When suspension, tire and brake related parts are excessively worn or deteriorated and the vehicle is

driven, ABS warning lamp, brake warning lamp and VDC warning lamp may turn ON, and the control may
not operate normally for VDC function, TCS function, ABS function, EBD 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 chassis control module) and active ride control function (control of chassis control module).

• ABS warning lamp, brake warning lamp and VDC warning lamp may turn ON, when only front wheel or rear

wheel is rotated using a free roller. This is not a malfunction, because it is caused by wheel speed difference
between wheel that is rotated and wheel that is not rotated. In this case, perform self-diagnosis, check self-
diagnosis results, and erase memory.

• When power supply voltage is not normal, ABS warning lamp, brake warning lamp and VDC warning lamp

turn ON. ABS actuator and electric unit (control unit) stops control for VDC function, TCS function, ABS func-
tion, EBD function, brake limited slip differential (BLSD) function, brake assist function, brake force distribu-
tion 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). Ordinary brake operates. After power supply returns to normal, ABS warning
lamp, brake warning lamp and VDC warning lamp turn OFF. The control becomes operative for VDC func-
tion, 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).

• Brake pedal vibrates and operation sound occurs during sudden acceleration and cornering, when 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) are operated. This is not a malfunction because it is caused by 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) that is operated normally.

• VDC warning lamp may turn ON and 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
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) may not normally operate, when
driving on a special road the is extremely slanted (bank in a circuit course). This is not a malfunction if the
status returns to normal 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 func-
tion (4WD models with gasoline engine), active trace control function (control of chassis control module) and
active ride control function (control of chassis control module) after the engine is started again. In this case,
perform self-diagnosis, check self-diagnosis results, and erase memory.

• A malfunction in yaw rate/side/decel G sensor system may be detected when the vehicle sharply turns dur-

ing a spin turn, acceleration turn or drift driving while VDC function and TCS function are OFF (VDC OFF
switch is pressed and VDC OFF indicator lamp is in ON status). This is not a malfunction if the status returns
