Be careful when accelerating, up-
shifting, downshifting or braking on
a slippery surface. Sudden accelera-
tion or engine braking could cause
the vehicle to skid or spin.
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 highspeed 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 highspeed 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.
Make sure your coolant is properly pro-
tected against freezing.
Only use “Toyota Super Long Life Coolant”
or similar high quality ethylene glycol
based non−silicate, non−amine, non−nitrite,
and non−borate coolant with long−life
hybrid organic acid technology. (Coolant
with long−life hybrid organic acid
technology is a combination of low
phosphates and organic acids.)
See “Checking the engine coolant level”
on page 382 in Section 7−2 for details of
coolant type selection.
For the U.S.A.—“Toyota Super Long Life
Coolant” is a mixture of 50% coolant and
50% deionized water. This coolant pro-
vides protection down to about −35C
(−31F).
For Canada—“Toyota Super Long Life
Coolant” is a mixture of 55% coolant and
45% deionized water. This coolant pro-
vides protection down to about −42C
(−44F).
NOTICE
Do not use plain water alone.
Check the condition of the battery and
cables.
Cold temperatures reduce the capacity of
any battery, so it must be in top shape
to provide enough power for winter start-
ing. Section 7−3 tells you how to visually
inspect the battery. Your Toyota dealer
and most service stations will be pleased
to check the level of charge.
Make sure the engine oil viscosity is
suitable for the cold weather.
See page 381 in Section 7−2 for recom-
mended viscosity. Leaving a heavy sum-
mer oil in your vehicle during winter
months may cause harder starting. If you
are not sure about which oil to use, call
your Toyota dealer—they will be pleased
to help.
Keep the door locks from freezing.
Squirt lock de−icer or glycerine into the
locks to keep them from freezing.

HITCHES
Use only a hitch which is recom-
mended by the hitch manufacturer and
conforms to the total trailer weight re-
quirement.
Follow the directions supplied by the
hitch manufacturer. Lubricate the hitch
ball with 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.
NOTICE
Do not use axlemounted hitches as
they can cause damage to the axle
housing, wheel bearings, wheels or
tires. Also, never install a hitch which
may interfere with the normal function
of an Energy Absorbing Bumper, if so
equipped.
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
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 page 385 in Sec-
tion 7−2 and page 411 in Section 8 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
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.
BREAKIN 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.
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 can not 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.
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.
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. If your vehicle has a manual
transmission, prevent excessive clutch
slippage by keeping engine rpm low
and not racing the engine. Always start
out in first gear.
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.

Before removing the jack, unhook the
tightening strap.
After storing the jack, make sure it is
securely held by the tightening strap.
This prevents the jack from flying for-
ward during a collision or sudden
stop.To remove the spare tire:
1. Loosen the nut and remove it.
2. Remove the spare tire cover.
3. Loosen the bolt and remove it.
4. Remove the spacer (with alumi-
num wheels).
Then take the spare tire out of the
vehicle.When storing the spare tire, put it in
place with the outer side of the wheel
facing up. Then secure the tire by re-
peating the above removal steps in
reverse order to prevent it from flying
forward during a collision or sudden
braking.

9. Lower the vehicle completely
and tighten the wheel nuts.
Turn the jack handle counterclock-
wise to lower the vehicle.
Use only the wheel nut wrench 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 other persons
around will not be injured as
the vehicle is lowered to the
ground.
Have the wheel nuts tightened
with torque wrench to 103 N·m
(10.5 kgf·m, 76 ft·lbf), as soon
as possible after changing
wheels. Otherwise, the nuts
may loosen and the wheels
may fall off, which could cause
a serious accident.
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.
10.Reinstall the wheel ornament.
1. Put the wheel ornament into posi-
tion.
Align the cutout of the wheel orna-
ment with the valve stem as shown.
2. Press hard 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.
11. Check the air pressure of the re-
placed tire.
Adjust the air pressure to the specifi-
cation designed on page 411 in Sec-
tion 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 infla-
tion 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
possible, tighten the wheel nuts to the
torque specified on page 411 in Sec-
tion 8 with a torque wrench. Have a
technician repair the flat tire and re-
place the spare tire with it.Initial adjustment of the tire pres-
sure warning system is necessary
after you have replaced your tires
or wheels. See “Tire pressure
warning system” on page 174 in
Section 17.
CAUTION
Before driving, make sure all the
tools, jack and flat tire are se-
curely in place in their storage
location to reduce the possibility
of personal injury during a colli-
sion or sudden braking.
