Cup holders
The cup holder is designed for holding
cups or drink- cans securely in its
holes. To use them, observe the follow-
ing illustrations.
CAUTION

Do not place anything else other
than cups or drink- cans on the cup
holder, as such items may be
thrown about and possibly injure
people in the vehicle during sudden
braking or in an accident.

To reduce the chance of injury in
case of an accident or a sudden
stop while driving, keep the cup
holder closed when it is not in use.
NOTICE
Type A onlyÐAs this holder is de-signed for holding soft cups only, donot place too heavy a cup, drink- canor bottle in it.

Brake pad wear limit indicators
The brake pad wear limit indicators on
your disc brakes give a warning noise
when the brake pads are worn to where
replacement is required.
If you hear a squealing or scraping noise
while driving, have the brake pads
checked and replaced by your Toyota
dealer as soon as possible. Expensive ro-
tor damage can result if the pads are not
replaced when necessary.
Luggage stowage precautions
When stowing luggage or cargo in the
vehicle, observe the following:

Put luggage or cargo in the rear deck
when at all possible. Be sure all items
are secured in place.

Be careful to keep the vehicle bal-
anced. Locating the weight as far for-
ward as possible helps maintain bal-
ance.

For better fuel economy, do not carry
unneeded weight.
CAUTION

To prevent luggage or packages
from sliding forward during braking,
do not stack anything behind the
front seats higher than the seat-
backs (access cab models). Keep
luggage or packages low, as close
to the floor as possible.

Never allow anyone to ride in the
rear deck. It is not designed for
passengers. They should ride in
their seats with their seat belts
properly fastened. Otherwise, they
are much more likely to suffer seri-
ous bodily injury, in the event of
sudden braking or a collision.

Do not drive with objects left on
top of the instrument panel. They
may interfere with the driver's field
of view. Or they may move during
sharp vehicle acceleration or turn-
ing, and impair the driver's control
of the vehicle. In an accident they
may injure the vehicle occupants.
NOTICE
Do not load the vehicle beyond the
cargo weight specified in Part 8.

Four- wheel drive modelsÐToyota rec-
ommends not using four- wheel drive on
dry hard- surfaced roads, because four-
wheel driving will cause unnecessary
noise and wear, and poor fuel econo-
my.

Four- wheel drive modelsÐIn cold tem-
peratures, noise may occur when driv-
ing in two- wheel drive before the trans-
fer is warmed up. Therefore, first drive
in four- wheel drive until the transfer is
warmed up.
CAUTION

Before driving off, make sure that
the parking brake is fully released
and the parking brake reminder
light is off.

Do not leave your vehicle unat-
tended while the engine is running.

Do not rest your foot on the brake
pedal while driving. It can cause
dangerous overheating, needless
wear, and poor fuel economy.

To drive down a long or steep hill,
reduce your speed and downshift.
Remember, if you ride the brakes
excessively, they may overheat and
not work properly.

Be careful when accelerating, up-
shifting, downshifting or braking on
a slippery surface. Sudden accelera-
tion or engine braking could cause
the vehicle to spin or skid.

Do not drive in excess of the speed
limit. Even if the legal speed limit
permits it, do not drive over 140
km/h (85 mph) unless your vehicle
has high- speed capability tires.
Driving over 140 km/h (85 mph) may
result in tire failure, loss of control
and possible injury. Be sure to con-
sult a tire dealer to determine
whether the tires on your vehicle
are high- speed capability tires or
not before driving at such speeds.

Do not continue normal driving
when the brakes are wet. If they are
wet, your vehicle will require a
longer stopping distance, and it
may pull to one side when the
brakes are applied. Also, the park-
ing brake will not hold the vehicle
securely.

HITCHES

If you wish to install a trailer hitch, you
should consult with your Toyota dealer.

Use only a hitch recommended by the
hitch manufacturer and the one which
conforms to the total trailer weight
requirement.

The hitch must be bolted securely to
the vehicle frame and installed accord-
ing to the hitch manufacturer 's instruc-
tions.

The hitch ball and king pin should have
a light coat of grease.

Toyota recommends removing the trail-
er hitch whenever you are not towing
a trailer to reduce the possibility of
additional damage caused by the hitch
if your vehicle is struck from behind.
After removing the hitch, seal any
mounting holes in the vehicle body to
prevent entry of pollutants such as ex-
haust fumes, dirt, water, etc.
NOTICE
Do not use axle- mounted hitches as
they can cause damage to the axlehousing, wheel bearings, wheels ortires. Also, never install a hitch which
may interfere with the normal functionof an Energy Absorbing Bumper, if soequipped.

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 applicable 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 sepa-
rated. For correct safety chain proce-
dures, follow the hitch or trailer
manufacturer 's recommendations.
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 trail-
er manufacturer in respect to the total
trailer weight.

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 bearings, 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 Guideº or Owner 's
Manual Supplementº.

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 regulation. If not,
install the rear view mirrors required
for towing purposes.
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.
