MATCHING TRAILER BALL HEIGHT TO
TRAILER COUPLER HEIGHT
No matter which class of tow hitch ap-
plies, for a safe trailer hookup, the trailer
ball setup on must be the proper height
for the coupler on the trailer.
BRAKES AND SAFETY CHAINS
Toyota recommends trailers with
brakes that conform to any applica-
ble federal and state/provincial regu-
lations.
A safety chain must always be used
between the towing vehicle and the
trailer. Leave sufficient slack in the
chain for turns. The chain should
cross under the trailer tongue to
prevent the tongue from dropping to
the ground in case it becomes dam-
aged or separated. For correct safety
chain procedures, follow the hitch or
trailer manufacturer ’s recommenda-
tions.
CAUTION
If the total trailer weight exceeds
453 kg (1000 lb.), trailer brakes are
required.
Never tap into your vehicle’s hy-
draulic system as it would lower its
braking effectiveness.
Never tow a trailer without using a
safety chain securely attached to
both the trailer and the vehicle. If
damage occurs to the coupling unit
or hitch ball, there is danger of the
trailer wandering over into another
lane.
TIRES
Ensure that your vehicle’s tires are
properly inflated. Adjust the tire infla-
tion pressure indicated below:
tire inflation pressure, kPa (psi)Front 220 (32)
Rear 240 (35)
See Section 7 −2 and Section 8 for in-
structions.
The trailer tires should be inflated to
the pressure recommended by the trail-
er manufacturer in respect to the total
trailer weight.

4. Turn the ignition switch on or push theheight control switch to turn on the
active height control suspension.
5. Wait for about 20 seconds until the rear vehicle height is lowered by the
automatic leveling function.
6. Make sure the hitch is disconnected. If not, raise the hitch higher and repeat
steps 2 through 5.
7. Move the vehicle forward in the “LO” mode where the hitch does not touch
anything in the “N” mode.
8. Put the active height control suspen- sion in the “N” mode.
PRETOWING SAFETY CHECK
Check that your vehicle remains level
when a loaded or unloaded trailer is
hitched. Do not drive if the vehicle has
an abnormal nose −up or nose −down
condition, and check for improper
tongue load, overload, worn suspension
or other possible causes.
Make sure the trailer cargo is securely
loaded so that it cannot shift.
Check that your rear view mirrors con-
form to any applicable federal, state/
provincial or local regulations. If not,
install the rear view mirrors required
for towing purpose.
TRAILER TOWING TIPS
When towing a trailer, your vehicle will
handle differently than when not tow-
ing. The three main causes of vehicle
trailer accidents are driver error, exces-
sive speed and improper trailer loading.
Keep these in mind when towing:
Before starting out, check operation of
the lights and all vehicle −trailer connec-
tions. After driving a short distance,
stop and recheck the lights and con-
nections. Before actually towing a trail-
er, practice turning, stopping and back-
ing with a trailer in an area away from
traffic until you learn the feel.
Because stopping distance may be in-
creased, vehicle −to −vehicle distance
should be increased when towing a
trailer. For each 16 km/h (10 mph) of
speed, allow at least one vehicle and
trailer length between you and the ve-
hicle ahead. Avoid sudden braking as
you may skid, resulting in jackknifing
and loss of control. This is especially
true on wet or slippery surfaces.
Avoid jerky starts or sudden accelera-
tion.
Avoid jerky steering and sharp turns.
The trailer could hit your vehicle in a
tight turn. Slow down before making a
turn to avoid the necessity of sudden
braking.
Remember that when making a turn,
the trailer wheels will be closer than
the vehicle wheels to the inside of the
turn. Therefore, compensate for this by
making a larger than normal turning
radius with your vehicle.
Backing with a trailer is difficult and
requires practice. Grip the bottom of
the steering wheel and move your hand
to the left to move the trailer to the
left. Move your hand to the right to
move the trailer to the right. (This pro-
cedure is generally opposite to that
when backing without a trailer). Also,
just turn the steering wheel a little at
a time, avoiding sharp or prolonged
turning. Have someone guide you when
backing to reduce the risk of an acci-
dent.

1. Get the required tools and sparetire.
1 Tool bag
2 Jac k
3 Spar e tir e
To prepare yourself for an emergency,
you should familiarize yourself with
the use of the jack, each of the tools
and their storage locations.
When storing the jack, put it in place
and secure to prevent it from flying
forward during a collision or sudden
braking.Turn the jack joint by hand.
To rem ov e: Tur n the joint in direction
1 until the jack is free.
To store: Turn the joint in direction 2
until the jack is fi rmly secured to pre-
vent it flying forward during a collision
or sudden braking.To remove the spare tire under the
luggage compartment:
1. Put a jack handle, jack handle ex- tensions and jack handle end to-
gether as shown in the illustration.

When connecting a jack handle exten-
sion with a jack handle end, use a
jack handle to tighten the bolts on the
joints as shown in the illustration.
When connecting the jack handle with
extension, tighten the wing bolt on the
joint securely. Make sure the hollow
meets the bolt on every joint when
you tighten the bolts.
NOTICE
Tighten all the joints securely.
Otherwise, the extension may
come off and it may damage
the paint or vehicle body.
2. Remove the access hole cover onthe rear bumper with a flathead
screwdriver.
To protect the paint, place several
sheets of paper over the paintwork.3. Insert the jack handle end into the lowering screw through the access
hole and turn it counterclockwise
with pushing it to the front lightly.

279
4. After the tire is lowered completelyto the ground, remove the holding
bracket as shown in the illustration.When storing the spare tire, put it in
place with the outer side of the wheel
facing up and hook the holding brack-
et as shown in the illustration. Then
secure the ti re, taking care that the
tire goes straight up without catching
on any other part, to prevent it from
moving during a collision or sudden
braking.
Check the tire from the side to see
that the tire is stored horizontally.
—Blocking the wheel
2. Block the wheel diagonally op- posite the flat tire to keep the
vehicle from rolling when it is
jacked up.
When blocking the wheel, place a
wheel block in front of one of the front
wheels or behind one of the rear
wheels.

281
—Positioning the jack
5. Position the jack at the correctjack point as shown. JACK POINTS:
Front—Under the frame side rail
Left rear—Under the rear axle
housing
Right rear—Under the bracket on
the rear axle housing
Make sure the jack is positioned on
a level and solid place.
Put a jack handle, jack handle exten-
sions, and jack handle end together
as shown in the illustration.
1 Jack handle end
2 Jack handle extensions
3 Jack handle
CAUTION
Make sure they are each securely
fixed with screws.

282
When connecting a jack handle exten-
sion with another extension and a jack
handle end, use a jack handle to tight-
en the bolts on the joints as shown
in the illustration. When connecting
the jack handle with extension, tight-
en the wing bolt on the jack handle
securely. Make sure the hollow meets
the bolt on any joint when you tighten
the bolts.NOTICE
Tighten all the joints securely.
Otherwise, the extension may
come off and it may damage
the paint or vehicle body.
—Raising your vehicle
6. After making sure no one is in
the vehicle, raise it high enough
so that the spare tire can be
installed.
Remember you will need more ground
clearance when putting on the spare
tire than when removing the flat tire.

284
—Reinstalling wheel nuts
8. Reinstall all the wheel nuts fin-ger tight.
Reinstall the wheel nuts (tapered end
inward) and tighten them as much as
you can by hand. Press back on the
tire and see if you can tighten them
more.
CAUTION
Never use oil or grease on the
bolts or nuts. Doing so may lead
to overtightening the nuts and
damaging the bolts. The nuts
may loosen and the wheels may
fall off, which could cause a seri-
ous accident. If there is oil or
grease on any bolt or nut, clean
it.
—Lowering your vehicle
9. Lower the vehicle completely and tighten the wheel nuts.
Turn the jack handle extension coun-
terclockwise with handle to lower the
vehicle, making sure the handle re-
mains firmly fitted onto the jack han-
dle extension.
Use only the wheel nut wrench and
turn it clockwise to tighten the nuts.
Do not use other tools or any addition-
al leverage other than your hands,
such as a hammer, pipe or your foot.
Make sure the wrench is securely en-
gaged over the nut.

285
Tighten each nut a little at a time in
the order shown. Repeat the process
until all the nuts are tight.
CAUTION

When lowering the vehicle,
make sure all portions of your
body and all other persons
around will not be injured as
the vehicle is lowered to the
ground.
 Have the wheel nuts tightened
with a torque wrench to 131
N·m (13.4 kgf·m, 96.6 ft·lbf), as
soon as possible after chang-
ing wheels. Otherwise, the
nuts may loosen and the
wheels may fall off, which
could cause a serious acci-
dent.
 Do not attach a heavily dam-
aged plastic wheel ornament.
It may fly off the wheel and
cause accidents while the ve-
hicle is moving.
—Reinstalling wheel ornament
10. Reinstall the wheel ornament.
Put the wheel ornament into position.
And press hand firmly on one side of
wheel ornament and then firmly tap
the other side around the edge of
wheel ornament with the heel of your
hand to snap into place.
CAUTION
Take due care in handling the or-
nament to avoid unexpected per-
sonal injury.
—After changing wheels
11. Check the air pressure of the re- placed tire.
Adjust the air pressu re to the specifi-
cation designated on page 344. If the
pressure is lower, dr ive slowly to the
nearest service station and fill to the
correct pressure.
Do not forget to reinstall the tire infla-
tion valve cap as dirt and moisture
could get into th e valve core and
possibly cause air leakage. If the cap
is missing, have a new one put on as
soon as possible.
12. Restow all the tools, jack and flat tire securely.
As soon after changing wheels as
possible, tighten the wheel nuts to the
torque specified on page 344 with a
torque wrench. Have a technician re-
pair the flat tire.
This is the same procedure for chang-
ing or rotating your tires.

(c) Towing with sling type truck
(c) Towing with sling type truck
NOTICE
Do not tow with sling type truck, ei-
ther from the front or rear. This may
cause body damage.
—Emergency towing
If towing is necessary, we recommend
you to have it done by your Toyota
dealer or a commercial tow truck ser-
vice.
If towing service is not available in an
emergency, your vehicle may be tempo-
rarily towed by a cable or chain se-
cured to front emergency towing hook.
Use extreme caution when towing the
vehicle.
A driver must be in the vehicle to steer it
and operate the brakes.
Towing in this manner may be done only
on hard− surfaced roads for a short dis-
tance and at low speeds. Also, the
wheels, axles, drive train, steering and
brakes must all be in good condition.
CAUTION
Use extreme caution when towing ve-
hicle. Avoid sudden starts or erratic
driving maneuvers which would place
excessive stress on the emergency
towing hook and towing cable or
chain. The hook and towing cable or
chain may break and cause serious
injury or damage.
NOTICE
 Do not use front and rear eyelets.
It is not designed for towing.
 Use only a cable or chain specifi-
cally intended for use in towing ve-
hicles. Securely fasten the cable or
chain to the towing hook provided.
 Never tow a vehicle from the rear
with four wheels on the ground.
This may cause serious damage to
the transmission.
Before towing, release the parking brake
and put the transmission in “N”. Unlock
the center differential. The key must be in
“ACC” (engine off) or “ON” (engine run-
ning).
