(k) Care must be taken when jacking up and supporting the
vehicle. Be sure to lift and support the vehicle at the prop-
er locations (See page IN±8).
Cancel the parking brake on the level place and
shift the transmission in N position.
When jacking up the front wheels of the vehicle, first
place stoppers behind the rear wheels.
When jacking up the rear wheels of the vehicle, first
place stoppers before the front wheels.
When either the front or rear wheels only should be
jacked up, set rigid racks and place stoppers in front
and behind of the other wheels on the ground.
After the vehicle is jacked up, be sure to support it
on rigid racks. It is extremely dangerous to do any
work on a vehicle raised on a jack, even for a job that
can be finished quickly.
(l) Observe the following precautions to avoid damage to the
following parts:
(1) Do not open the cover or case of the ECU unless
absolutely necessary. (If the IC terminals are
touched, the IC may be destroyed by static electric-
ity.)
(2) To disconnect vacuum hoses, pull off the end, not
the middle of the hose.
(3) To pull apart electrical connectors, pull on the con-
nector itself, not the wires.
(4) Be careful not to drop electrical components, such
as sensors or relays. If they are dropped on a hard
floor, they should be replaced and not reused.
(5) When steam cleaning an engine, protect the elec-
tronic components, air filter and emission±related
components from water.
(6) Never use an impact wrench to remove or install
temperature switches or temperature sensors.

HINT:
Perform the following before installation.
When using safety stands and jack:
(1) Jack up the rear axle until the bottom of the rear
pneumatic cylinder touches the rear axle and fit the
seating pin on the lower side of the rear pneumatic
cylinder into the rear axle.
NOTICE:
Do not extend the rear pneumatic cylinder in order to
fit the seating pin into the hole.
Make sure that the seating pin on the lower side of the
rear pneumatic cylinder fits in the hole in the rear
axle.
(2) Remove the safety stands with care not to extend
the rear pneumatic cylinder when jacking down the
vehicle till it sits on the ground.
NOTICE:
Make sure that the diaphragm (rubber part) of the pneumat-
ic cylinder is not deformed.
(3) Start the engine and replenish the rear pneumatic
cylinder with air.
(e) When using a swing arm type lift:
(1) Lower the vehicle till the tires hit the ground, and
continue lowering slowly until the bottom of the rear
pneumatic cylinder touches the rear axle.
(2) Align the seating pin on the cylinder with the hole in
the rear axle and install the rear pneumatic cylinder
on the rear axle.
NOTICE:
Do not extend the rear pneumatic cylinder by lifting
up the rear axle housing after fitting the seating pin.
Make sure that the diaphragm (rubber part) of the
pneumatic cylinder is not deformed.
(3) Lower the lift carefully so as not to extend the rear
pneumatic cylinder.
NOTICE:
Make sure that the diaphragm (rubber part) of the pneumat-
ic cylinder is not deformed.

NOTICE
If the vehicle height is changed fre-
quently when the vehicle is heavily
loaded, the compressor may over-
heat, causing the vehicle height ad-
justment operation to stop.
Before you lower the vehicle height
with the height select switch, check
under the vehicle to make sure
nothing to damage the vehicle or
no one to be injured is there and
that the underbody of the vehicle
does not touch the ground.
After unloading, the height of a ve-
hicle equipped with the rear height
control air suspension becomes
slightly higher than the normal ve-
hicle height. Take sufficient care
where the overhead height is re-
stricted.
Do not select ªLOº mode for bumpy
roads. If the underbody of the ve-
hicle touches the road surface, the
vehicle may be damaged.
If you attempt to adjust the vehicle height
with anything such as snow, ice, or stones
in contact with the vehicle body, the ve-
hicle height may not change. In this case,
stop the vehicle, press the mode select
switch, and check that manual control
mode indicator light comes on. Then, re-
move the obstruction.
CAUTION
If you drive through water, set the
vehicle height to ªHIº with the height
select switch and then change to
manual control mode by pushing the
mode select switch. Do not exceed 30
km/h (18 mph) or ªHIº mode will au-
tomatically change to ªNº mode. Do
not drive through water deeper than
about 700 mm (28 in.) even if the
vehicle height is in ªHIº mode.
NOTICE
When jacking up or installing tire
chains, be sure to set manual con-
trol mode by pushing the mode se-
lect switch and stop the engine.
Otherwise, the vehicle height may
change because of the automatic
leveling function, resulting in an ac-
cident.
If your vehicle must be towed, set
the vehicle height to ªNº and
change to manual control mode.
Otherwise, the vehicle height may
change because of the automatic
leveling function, resulting in an ac-
cident.
If your vehicle gets stuck in a
ditch, set manual control mode by
pushing the mode select switch.
Otherwise, the vehicle height may
change because of the automatic
leveling function, resulting in an ac-
cident.

In manual control mode, the automatic lev-
eling function is turned off. When the ve-
hicle height is changed because of the
conditions (load etc.), you can adjust the
vehicle height with the height select
switch.
In manual control mode, if the vehicle
speed exceeds 30 km/h (18 mph), auto-
matic control mode is activated and ªNº is
selected automatically.
If you attempt to adjust the vehicle height
with anything such as snow, ice, or stones
in contact with the vehicle body, the ve-
hicle height may not change. In this case,
stop the vehicle and remove the obstruc-
tion.
CAUTION
If you drive through water, set the
vehicle height to ªHIº with the height
select switch and then change to
manual control mode by pushing the
mode select switch. Do not exceed 30
km/h (18 mph) or ªHIº mode will au-
tomatically change to ªNº mode. Do
not drive through water deeper than
about 700 mm (28 in.) even if the
vehicle height is in ªHIº mode.
NOTICE
When jacking up or installing tire
chains, be sure to set manual con-
trol mode by pushing the mode se-
lect switch and stop the engine.
Otherwise, the vehicle height may
change because of the automatic
leveling function, resulting in an ac-
cident.
If your vehicle must be towed, set
the vehicle height to ªNº in auto-
matic control mode, then select
manual control mode by pushing
the mode select switch. Otherwise,
the vehicle height may change be-
cause of the automatic leveling
function, resulting in an accident.
If your vehicle gets stuck in a
ditch, set manual control mode with
the mode select switch. Otherwise,
the vehicle height may change be-
cause of the automatic leveling
function, resulting in an accident.
(b) Vehicle height adjustment
To change the vehicle height in manual
mode, push the height select switch on
either side of ªº (higher) or ªº
(lower).
A higher vehicle height is suitable when
driving on bumpy roads and through water.
A lower vehicle height allows for easy
access to the vehicle (getting in and out)
and easy loading and unloading.
When you are driving on bumpy roads,
which may cause the suspension to fully
elongate, the rear height control air sus-
pension may not operate.

CAUTION
Do not attempt to remove the radiator
cap when the engine and radiator are
hot. Serious injury could result from
scalding hot fluid and steam blown
out under pressure.
7. After the engine coolant temperature
has cooled to normal, again check the
coolant level in the reservoir. If neces-
sary, bring it up to half full again. Seri-
ous coolant loss indicates a leak in the
system. You should have it checked as
soon as possible at your Toyota dealer.
1. Reduce your speed gradually,
keeping a straight line. Move cau-
tiously off the road to a safe place
well away from the traffic. Avoid
stopping on the center divider of
a highway. Park on a level spot
with firm ground.
2. Stop the engine and turn on your
emergency flashers.
3. Firmly set the parking brake and
put the transmission in ªPº.
4. Have everyone get out of the ve-
hicle on the side away from traffic.
5. Read the following instructions
thoroughly.CAUTION
When jacking, be sure to observe
the following to reduce the possi-
bility of personal injury:
Follow jacking instructions.
Do not put any part of your
body under the vehicle sup-
ported by the jack. Otherwise,
personal injury may occur.
Do not start or run the engine
while your vehicle is supported
by the jack.
Stop the vehicle on a level firm
ground, firmly set the parking
brake and put the transmission
in ªPº. Block the wheel diago-
nally opposite to the one being
changed if necessary.
