(b) Measure the time lag.
When the shift lever is shifted while the engine is idling, there will be a certain time lapse or lag before
the shock can be felt. This is used for checking the condition of the clutch and brake.
NOTICE:

Do the test at normal operating fluid temperature 70 to 80 °C (158 to 176 °F).

Be sure to allow 1 minute interval between tests.

Take 3 measurements and take the average value.
(1) Fully apply the parking brake.
(2) Start the engine and check idle speed.
Idle speed (In N position and air conditioner OFF): 700 ± 50 rpm.
(3) Shift the shift lever from N to D position. Using a stop watch, measure the time from when the
lever is shifted until the shock is felt.
Time lag:
N " D Less than 1.2 seconds
(4) In the same manner, measure the time lag for N " R.
Time lag:
N " R Less than 1.5 seconds
Evaluation (If N " D time or N " R time lag is longer than the specified):

15. HYDRAULIC TEST
Measure the line pressure.
NOTICE:

Do the test at normal operation fluid temperature 70
to 80°C (158 to 176°F).

The line pressure test should always be carried out in
pairs. One technician should observe the conditions
of wheels or wheel stoppers outside the vehicle while
the other is doing the test.

Be careful to prevent SST's hose from interfering with
the exhaust pipe.

This check must be conducted after checking and ad-
justing engine.

Perform under condition that A/C is OFF.

When conducting stall test, do not continue more
than 10 seconds.
(1) Warm up the ATF.
(2) Remove the test plug on the transmission case cen-
ter right side and connect SST.
SST 09992-00095 (09992-00231, 09992-00271)
(3) Fully apply the parking brake and chock the 4
wheels.
(4) Start the engine and check idling speed.
(5) Keep your left foot pressing firmly on the brake ped-
al and shift into D position.
(6) Measure the line pressure when the engine is idling.
(7) Depress the accelerator pedal all the way down.
Quickly read the highest line pressure when engine
speed reaches stall speed.
(8) In the same manner, do the test in R position.
Specified line pressure:

, psi)R position kPa (kgf/cm2, psi)

1. ABS Operation
If the brake pedal is depressed suddenly, the ABS controls the hydraulic pressure of the wheel cylinders for all the four
wheels to automatically avoid wheel locking and ensure the directional and steering stability of the vehicle. If the brake pedal
is depressed suddenly, the ABS & BA & TRAC & VSC ECU controls the solenoids in the actuators using the signals from the
sensors to move the brake fluid to the reservoir in order to release the braking pressure applied to the wheel cylinder. If the
ABS & BA & TRAC & VSC ECU detects that the fluid pressure in the wheel cylinder is insufficient, the ECU controls the
solenoids in the actuators to increase the braking pressure.
2. Traction Control Operation
The traction control system controls the engine torque, the hydraulic pressure of the driving wheel cylinders, slipping of the
wheels which may occur at start or acceleration of the vehicle, to ensure an optimal driving power and vehicle stability
corresponding to the road conditions.
3. VSC Operation
Unexpected road conditions, vehicle speed, emergency situation, and any other external factors may cause large under- or
over-steering of the vehicle. If this occurs, the VSC system automatically controls the engine power and wheel brakes to
reduce the under- or over-steering.
To reduce large over-steering :
If the VSC system determines that the over-steering is large, it activates the brakes for the outer turning wheels depending
on the degree of the over-steering to produce the moment toward the outside of the vehicle and reduce the over-steering.
To reduce large under-steering :
If the VSC system determines that the under-steering is large, it controls the engine power and activates the rear wheel
brakes to reduce the under-steering.
VSC indicator light
If an error occurs in the VSC system, the VSC indicator lights up to warn the driver.
4. Traction Mode and VSC Function
When the center differential of the transfer is locked, the VSC function is turned off. At this time, the VSC OFF indicator light
in the combination meter will come on, and informs the driver that the VSC function is OFF.
5. Mutual System Control
To efficiently operate the VSC system at its optimal level, the VSC system and other control systems are mutually controlled
while the VSC system is being operated.
Engine throttle control
The engine power does not interfere with the VSC brake control by controlling the opening of the throttle and reducing the
engine output.
Engine control and electronically controlled transmission control
The strong braking force does not interfere with the braking force control of the VSC system by turning off the accel. and
reducing changes in the driving torque at shift-down.
VSC system operation indication
The slip indicator light flashes and the buzzer sounds intermittently to warn the driver that the current road is slippery, while
the VSC system is being operated.
6. Fail Safe Function
If an error occurs in the ABS & BA & TRAC & VSC ECU, sensor signals, and/or actuators, the ABS & BA & TRAC & VSC
ECU inhibits the brake actuator control and inputs the error signal to the engine control module. According to the error signal,
the brake actuator turns off the solenoid and the engine control module rejects any electronically controlled throttle open
request from the VSC system. As a result, the vehicle functions without the ABS, BA, TRAC, and VSC systems.

GENERAL MAINTENANCE
1. GENERAL NOTICE

Maintenance items may vary from country to country. Check the owner's manual supplement in which
the maintenance schedule is shown.

Every service item in the periodic maintenance schedule must be performed.

Periodic maintenance service must be performed according to whichever interval in the periodic main-
tenance schedule occurs first, the odometer reading (miles) or the time interval (months).

Maintenance services after the last period should be performed at the same interval as before unless
otherwise noted.

Failure to do even one item can cause the engine to run poorly and increase exhaust emissions.
2. WINDSHIELD WASHER FLUID
Check that there is sufficient fluid in the tank.
3. ENGINE COOLANT LEVEL
Check that the coolant level is between the LEVEL lines on the see-through reservoir at normal tem-
perature (20°C (68°F)).
4. RADIATOR AND HOSES
(a) Check that the front of the radiator is clean and not blocked with leaves, dirt or bugs.
(See page CO-14)
(b) Check the hoses for cracks, kinks, rot or loose connections.
5. BATTERY ELECTROLYTE LEVEL

Check the indicator.

When the indicator color is blue, the condition is satisfactory. A red color indicates that distilled water
must be added, and white indicates that charging is necessary.
6. BRAKE FLUID LEVELS
Check that the brake fluid level is near the upper level line on the see-through reservoir.
(See page BR-4)
7. ENGINE DRIVE BELTS
Check drive belt for fraying, cracks, wear or oiliness.
8. ENGINE OIL LEVEL
Check the level on the dipstick with the engine turned off.
9. POWER STEERING FLUID LEVEL

Check the level on the dipstick.

The level should be in the ºHOTº or ºCOLDº range depending on the fluid temperature.
10. AUTOMATIC TRANSMISSION FLUID LEVEL
Visually check the overflow plug and oil pan for fluid leaks or traces of fluid.
