130BRAKES AND SAFETY CHAINS


Toyota recommends trailers with
brakes that conform to any appli-
cable federal and state/provincial
regulations.

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
damaged or separated. For correct
safety chain procedures, follow the
hitch or trailer manufacturer's rec-
ommendations.
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. See Chapter 7-2 for
instructions.

The trailer tires should be inflated to
the pressure recommended by the
trailer manufacturer in respect to the
total trailer weight.
TRAILER LIGHTS

Trailer lights must comply with federal,
state/provincial and local regulations.
See your local recreational vehicle
dealer or rental agency for the correct
type of wiring and relays for your trail-
er. Check for correct operation of the
turn signals and stop lights each time
you hitch up. Direct splicing may dam-
age 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 ve-
hicle with any new power train compo-
nent (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 re-
quire more frequent maintenance due
to the additional load. For this informa-
tion, please refer to the scheduled
maintenance information in the Own-
er 's Manual Supplement/Maintenance
Scheduleº.

Retighten all fixing bolts of the towing
ball and bracket after approximately
1000 km (600 miles) of trailer driving.
PRE-T OWING 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 suspen-
sion or other possible causes.

Make sure the trailer cargo is securely
loaded so that it can not shift.

Check that your rear view mirrors con-
form to any applicable federal, state/
provincial or local regulation. If not,
install the rear view mirrors required
for towing purpose.

9. Lower the vehicle completely and
tighten the wheel nuts.
Turn the jack handle counterclockwise to
lower the vehicle.
Use only the wheel nut wrench and turn it
clockwise to tighten the nuts. Do not use
other tools or any additional leverage oth-
er 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 or-
der shown. Repeat the process until all
the nuts are tight.Steel wheels

11. Check the air pressure of the
replaced tire.
Adjust
the air pressure to the specification
designated in Part 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 as possible after changing
wheels, tighten the wheel nuts to the
torque specified in Part 8 with a torque
wrench, have a technician repair the flat
tire and replace the spare tire with it.
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
injury during a collision or sudden
braking. CAUTION
!
If towing is necessary, we recommend
you have it done by your T
oyota dealer
or a commercial tow truck service.
Proper equipment will help ensure that
your vehicle is not damaged while being
towed. Commercial operators are gener-
ally aware of the state/provincial and local
laws pertaining to towing.
Your vehicle can be damaged if it is towed
incorrectly. Although most operators
know the correct procedure, it is possible
to make a mistake. To avoid damage to
your vehicle, make sure the following few
precautions are observed. If necessary,
show this page to the tow truck driver.
TOWING PRECAUTIONS:
Use a safety chain system for all towing,
and abide by the state/provincial and local
laws. The wheels and axle on the ground
must be in good condition. If they are
damaged, use a towing dolly.
(a) Using flat bed truck
Toyota recommends this as the best
method for your vehicle.

If towing service is not available in an
emergency, your vehicle may be tem-
porarily towed by a cable secured to
one of the emergency towing eyelets
under 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.
Before towing, release the parking brake
and put the transmission in Nº. The key
must be in ACCº (engine off) or ONº (en-
gine running).
CAUTION!
If the engine is not running, the
power assist for the brakes and
steering will not work so steering
and braking will be much harder
than usual.
If you cannot shift the selector lever
out of Pº position to other positions
even though the brake pedal is de-
pressed, use the shift lock override
button as follows:
1. Turn the ignition key to LOCKº
position. Make sure the parking brake
is set.
2. Pry up the cover with a flat-bladed
screwdriver or equivalent.3. Insert the screwdriver or equivalent
into the hole to push down the shift
lock override button. You can shift out
of Pº position only while pushing the
button.
4. Shift into Nº position.
5. Insert the cover.
6. Start the engine. For your safety,
keep the brake pedal depressed.
Be sure to have the system checked by
your Toyota dealer as soon as possible.
