TRAILER LIGHTS
Your vehicle is equipped with a wire
harness stored in the rear end under
body. Some models are fitted with a
socket for trailer lights under the rear
bumper. Use either of them to connect
and operate the trailer lights. However,
the trailer lights must comply with fed-
eral, state/provincial and local regula-
tions. See your local recreational ve-
hicle dealer or rental agency for the
correct type of wiring and relays for
your trailer. Check for correct operation
of the turn signals and stop lights each
time you hitch up. Direct splicing may
damage your vehicle’s electrical system
and cause a malfunction of your lights.BREAK IN SCHEDULE
Toyota recommends that you do not
tow a trailer with a new vehicle or a
vehicle with any new power train com-
ponent (engine, transmission, differen-
tial, wheel bearing, etc.) for the first
800 km (500 miles) of driving.
MAINTENANCE
If you tow a trailer, your vehicle will
require more frequent maintenance due
to the additional load. For this informa-
tion, please refer to the scheduled
maintenance information in the “Sched-
uled Maintenance Guide” or “Owner ’s
Manual Supplement”.
Retighten all fixing bolts of the towing
ball and bracket after approximately
1000 km (600 miles) of trailer driving.PRE TOWING 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.

Turn the jack joint by hand.
To remove: Turn the joint in direction 1
until the jack is free.
To store: Turn the joint in direction 2 until
the jack is firmly secured to prevent it
flying forward during a collision or sudden
braking.To remove the spare tire:
1. Insert the end of the jack handle into
the lowering screw and turn it counter-
clockwise.
2. After the tire is lowered completely to
the ground, remove the holding brack-
et.
When storing the spare tire, put it in place
with the outer side of the wheel facing up.
Then secure the tire, taking care that the
tire goes straight up without catching on
any other part, to prevent it from flying
forward during a collision or sudden brak-
ing.
—Blocking the wheel
2. Block the wheel diagonally opposite
the flat tire to keep the vehicle from
rolling when it is jacked up.
When blocking the wheel, place a wheel
block from the front for the front wheels
or from the rear for the rear wheels.

—Lowering your vehicle
9. Lower the vehicle completely and
tighten the wheel nuts.
Turn the jack handle extension counter-
clockwise with handle to lower the vehicle,
making sure the handle remains firmly
fitted onto the jack handle extension.
Use only the wheel nut wrench and turn
it clockwise to tighten the nuts. Do not
use other tools or any additional leverage
other than your hands, such as a hammer,
pipe or your foot. Make sure the wrench
is securely engaged over the nut.
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 oth-
er persons around will not be injured
as the vehicle is lowered to the
ground.

10. Reinstall the wheel ornament.
Put the wheel ornament into position and
then tap it firmly with the side or heel of
your hand to snap it into place.
CAUTION
Take due care in handling the orna-
ment to avoid unexpected personal
injury.
—After changing wheels
11. Check the air pressure of the re-
placed tire.
Adjust the air pressure to the specification
designated in Section 8. If the pressure is
lower, drive slowly to the nearest service
station and fill to the correct pressure.
Do not forget to reinstall the tire inflation
valve cap as dirt and moisture could get
into the 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 pos-
sible, tighten the wheel nuts to the torque
specified in Section 8 with a torque
wrench. Have a technician repair the flat
tire.
CAUTION
Before driving, make sure all the
tools, jack and flat tire are securely
in place in their storage location to
reduce the possibility of personal in-
jury during a collision or sudden
braking.

—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 the emergency towing hook.
Use extreme caution when towing ve-
hicles.
Four wheel drive models—Before towing,
remove the towing hook cover in front of
the emergency towing hook. By doing this,
it prevents the towing cable from damag-
ing the bumper. See “—Removing towing
hook cover for emergency towing” for in-
structions.
NOTICE
Only use specified towing hook;
otherwise your vehicle may be dam-
aged.
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-
hicles. 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
Use only a cable or chain specifically
intended for use in towing vehicles.
Securely fasten the cable or chain to
the towing hook provided.
Before towing, release the parking brake
and put the transmission in “N” and the
transfer in “H” mode (high speed position,
two wheel drive). The key must be in
“ACC” (engine off) or “ON” (engine run-
ning).
CAUTION
If the engine is not running, the pow-
er assist for the brakes and steering
will not work so steering and braking
will be much harder than usual.
