STEERING SYSTEM
PRECAUTION
Care must be taken to replace parts properly because they could affect the performance of the
steering system and result in a driving hazard.
The SEQUOIA is equipped with an SRS (Supplemental Restraint System) such as the driver air-
bag and front passenger airbag. Failure to carry out service operation in the correct sequence
could cause the SRS to unexpectedly deploy during servicing, possibly leading to a serious
accident. Before servicing (including removal or installation of parts, inspection or replace-
ment), be sure to read the notices precautionary in the RS section.
When disconnecting the battery terminal, initialize the following system after the terminal is re-
connected.
System NameSee Page
Back Door Power Window Control SystemBE±77
When replacing the steering angle sensor, drive the vehicle straight ahead at a speed of 6.5 mph
(10.5 km/h) or more. Accordingly, zero point calibration of the steering angle sensor is per-
formed.
After performing ºFront wheel alignment adjustmentº, clearing and reading the yaw rate & de-
celeration sensor zero point calibration data is necessary (See page DI±897).

DRIVE BELT
INSPECTION
INSPECT DRIVE BELT
Visually check the belt for excessive wear, frayed cords, etc.
If any defect has been found, replace the drive belt.
HINT:
Cracks on the rib side of the belt are considered acceptable. If
the missing chunks from the ribs are found on the belt, it should
be replaced.
HINT:
ºNew beltº refers to a belt which has been used less than
5 minutes on a running engine.
ºUsed beltº refers to a belt which has been used on a run-
ning engine for 5 minutes or more.
After installing a belt, check that it fits properly in the
ribbed grooves.
Check with your hand to confirm that the belt has not
slipped out of the groove on the bottom of the pulley.
After installing a new belt, run the engine for about 5 min-
utes and recheck the belt tension.

BLEEDING
1. CHECK FLUID LEVEL (See page SR±5)
2. JACK UP FRONT OF VEHICLE AND SUPPORT IT
WITH STANDS
3. TURN STEERING WHEEL
With the engine stopped, turn the wheel slowly from lock to lock
several times.
4. LOWER VEHICLE
5. START ENGINE
Run the engine at idle for a few minutes.
6. TURN STEERING WHEEL
(a) With the engine idling, turn the wheel left or right to the full
lock position and keep it there for 2 to 3 seconds, then turn
the wheel to the opposite full lock position and keep it
there for 2 to 3 seconds.
(b) Repeat (a) several times.
7. STOP ENGINE
8. CHECK FOR FOAMING OR EMULSIFICATION
If the system has to be bled twice specifically because of foam-
ing or emulsification, check for fluid leaks in the system.
9. CHECK FLUID LEVEL (See page SR±5)

1. CHECK FLUID LEVEL
(a) Keep the vehicle level.
(b) With the engine stopped, check the fluid level in the reser-
voir.
If necessary, add fluid.
Fluid: ATF DEXRON® II or III
HINT:
When the fluid is hot, check that the fluid level is within the HOT
range on the reservoir/reservoir cap dipstick.
If the fluid is cold, check that it is within the COLD range.
(c) Start the engine and run at idle.
(d) Turn the steering wheel from the lock position to the other
side of lock position several times to boost fluid tempera-
ture.
Fluid temperature: 80°C (176°F)
(e) Check for foaming or emulsification.
If there is foaming or emulsification, bleed the air from the power
steering system (See page SR±4).
(f) With the engine idling, measure the fluid level in the reser-
voir.
(g) Stop the engine.
(h) Wait a few minutes and remeasure the fluid level in the
reservoir.
Maximum fluid level rise: 5 mm (0.20 in.)
If a problem is found, bleed the air from the power steering sys-
tem (See page SR±4).
(i) Check the fluid level.
