If the steering axis inclination is not within the specified values,
after the camber and caster have been correctly adjusted, re-
check the steering knuckle and front wheel bearing for loose-
ness.
4. ADJUST CAMBER AND CASTER
(a) Loosen the front and/or rear adjusting cam set bolts.
(b) Adjust the camber and caster by turning the front and/or
rear adjusting cams (See adjustment chart).
HINT:
Try to adjust the camber and caster to the center of the specified
values.

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).

RECALLING THE MEMORIZED POSITION
When you push button ª1º or ª2º, a
beep will sound and the driving posi-
tion will be automatically adjusted to
the position recorded for that button.
The memorized position can be recalled
under the following conditions:

The ignition key is in the ªON position
and the shift lever is in the ªPº posi-
tion.

The key is not in the ignition switch
and less than 30 seconds have passed
since opening the driver 's door.To stop the operation, push any driving
position memory button.
To reactivate the system, push the button
ª1º or ª2º again.
If the vehicle's battery is disconnected,
the memory will be erased and the posi-
tions will have to be set again.
CAUTION

Do not start the vehicle while the
adjustment are being made.

Take care not to select the wrong
button, or the seat could strike the
rear passenger or hit your body
against the steering wheel. If this
happens, you can stop the move-
ment by pressing another driving
position memory switch, or de-
pressing the brake pedal.
Toyota strongly urges that the driver and
passengers in the vehicle be properly re-
strained at all times with the seat belts
provided. Failure to do so could increase
the chance of injury and/or the severity of
injury in accidents.
The seat belts provided for your vehicle
are designed for people of adult size,
large enough to properly wear them.
Child. Use a child restraint system ap-
propriate for the child until the child be-
comes large enough to properly wear the
vehicle's seat belts. See ªChild restraintº
on page 107 in this Section for details.
If a child is too large for a child restraint
system, the child should sit in the rear
seat and must be restrained using the
vehicle's seat belt. According to accident
statistics, the child is safer when properly
restrained in the rear seat than in the
front seat.
If a child must sit in the front seat, the
seat belts should be worn properly. If an
accident occurs and the seat belts are not
worn properly, the force of the rapid infla-
tion of the airbag may cause death or
serious injury to the child.

LOW TIRE PRESSURE WARNING LIGHT
This light comes on when the ignition key
is turned to the ªONº position. It goes off
after a few seconds. This indicates that
the tire pressure warning system is func-
tioning properly.If the low tire pressure warning light
comes on or blinks, do the following.
If the warning light comes on:
Stop your vehicle in a safe place as
soon as possible and check that the
inflation pressure of all tires (including
the spare tire) is as specified on the
tire and loading information label. (See
ªChecking tire inflation pressureº on
page 429 in Section 7±2.) If the warning
light comes on even after tire inflation
pressure adjustment, you may have a
flat tire. If you have a flat tire, replace
it with the spare tire. For details, see
ªIf you have a flat tireº on page 387 in
Section 4.
The warning light goes off a few minutes
after air is put into the deflated tire.
This warning light may turn on due to
natural causes such as natural air leaks
or tire pressure changes caused by tem-
perature. In this case, adjusting the tire
pressure will turn off the warning light.
CAUTION
When the tire pressure warning light
comes on, observe the following in-
structions:

Depending on the conditions, re-
duce to an appropriate speed as
soon as possible.

Adjust the tire pressure to the spe-
cified level as soon as possible.

Avoid abrupt steering wheel maneu-
vering and braking. Tire deteriora-
tion may reduce steering wheel con-
trol and brake effectiveness. This
may lead to serious injury or death.

The tire pressure warning system
may not activate immediately if sud-
den bursts of air leakage occur.
