In a rollover crash, an unbelted per-
son is significantly more likely to
die than a person wearing a seat
belt. Therefore, the driver and all
passengers should fasten their seat
belts whenever the vehicle is mo-
ving.

When driving off- road or in rugged
terrain, do not drive at excessive
speeds, jump, make sharp turns,
strike objects, etc. This may cause
loss of control or vehicle rollover
causing death or serious injury. You
are also risking expensive damage
to your vehicle's suspension and
chassis.
NOTICE

If driving through water, such as
when crossing shallow streams,
first check the depth of the water
and the bottom of the river bed for
firmness. Drive slowly and avoid
deep water.

Take all necessary safety measures
to ensure that water damage to the
engine or other components does
not occur.
Water entering the engine air intake
will cause severe engine damage.
Water can wash the grease from
wheel bearings, causing rusting and
premature failure, and may also en-
ter the differentials, transmission
and transfer case, reducing the gear
oil's lubricating qualities.

Sand and mud that has accumulated
in brake drums and around brake
discs may affect braking efficiency
and may damage brake system com-
ponents.

Always perform a maintenance in-
spection after each day of off- road
driving that has taken you through
rough terrain, sand, mud, or water.
For scheduled maintenance informa-
tion, refer to the Scheduled Main-
tenance Guideº or Owner's Manual
Supplementº.
Make sure your coolant is properly pro-
tected against freezing.
Only use Toyota Super Long Life Coolantº
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 levelº
on page 383 in Section 7- 2 for details of
coolant type selection.
For the U.S.A.ÐToyota Super Long Life
Coolantº is a mixture of 50% coolant and
50% deionized water. This coolant pro-
vides protection down to about -35C
(- 31F).
For CanadaÐToyota Super Long Life
Coolantº 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 380 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 dealerÐthey 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.
Use a washer fluid containing an anti-
freeze solution.
This product is available at your Toyota
dealer and most auto parts stores. Follow
the manufacturer 's directions for how
much to mix with water.NOTICE
Do not use engine antifreeze or any
other substitute because it may dam-
age your vehicle's paint.
Do not use your parking brake when
there is a possibility it could freeze.
When parking, put the transmission into
Pº and block the rear wheels. Do not use
the parking brake, or snow or water accu-
mulated in and around the parking brake
mechanism may freeze, making it hard to
release.
Keep ice and snow from accumulating
under the fenders.
Ice and snow built up under your fenders
can make steering difficult. During bad
winter driving, stop and check under the
fenders occasionally.
Depending on where you are driving,
we recommend you carry some emer-
gency equipment.
Some of the things you might put in the
vehicle are tire chains, window scraper,
bag of sand or salt, flares, small shovel,
jumper cables, etc.
Your vehicle is not designed to be
dinghy towed (with four wheels on the
ground) behind a motorhome.
NOTICE
Do not tow your vehicle with four
wheels on the ground. This may
cause serious damage to your vehicle.
Dinghy towing

'05 HIGHLANDER_U (L/O 0409)

2005 HIGHLANDER from Nov. '04 Prod. (OM48570U)
Never load the trailer with more
weight in the back than in the
front. About 60% of the trailer load
should be in the front half of the
trailer and the remaining 40% in the
rear.
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 axle
housing, wheel bearings, wheels or
tires.
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. See page 385 in Sec-
tion 7- 2 and page 410 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

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 regulations. 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.

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.

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.

Crosswinds and rough roads will ad-
versely affect handling of your vehicle
and trailer, causing sway. Pay attention
to the rear from time to time to pre-
pare yourself for being passed by large
trucks or buses, which may cause your
vehicle and trailer to sway. If swaying
happens, firmly grip the steering wheel
and reduce speed immediately but
gradually. Never increase speed. Steer
straight ahead. If you make no extreme
correction with the steering or brakes,
the vehicle and trailer will stabilize.

Be careful when passing other ve-
hicles. Passing requires considerable
distance. After passing a vehicle, do
not forget the length of your trailer and
be sure you have plenty of room be-
fore changing lanes.

In order to maintain engine braking effi-
ciency, do not use overdrive.

Because of the added load of the trail-
er, your vehicle's engine may overheat
on hot days (at temperatures over
30C [85F]) when going up a long or
steep grade with a trailer. If the engine
coolant temperature gauge indicates
overheating, immediately turn off the air
conditioning (if in use), pull off the road
and stop in a safe spot. Refer to If
your vehicle overheatsº on page 336 in
Section 4.

Always place wheel blocks under both
the vehicle and trailer wheels when
parking. Apply the parking brake firmly.
Put the transmission in Pº. Avoid park-
ing on a slope with a trailer, but if it
cannot be avoided, do so only after
performing the following:
1. Apply the brakes and hold.
2. Have someone place wheel blocks un-
der both the vehicle and trailer wheels.
3. When the wheel blocks are in place,
release your brakes slowly until the
blocks absorb the load.
4. Apply the parking brake firmly.
5. Shift into Pº and turn off the engine.

'05 HIGHLANDER_U (L/O 0409)

When restarting out after parking on a
slope:
1. With the transmission in Pº position,
start the engine. Be sure to keep the
brake pedal depressed.
2. Shift into gear.
3. Release the parking brake and brake
pedal and slowly pull or back away
from the wheel blocks. Stop and apply
your brakes.
4. Have someone retrieve the blocks.CAUTION

Do not exceed 72 km/h (45 mph) or
the posted towing speed limit,
whichever is lower. Because insta-
bility (swaying) of a towing vehicle-
trailer combination usually in-
creases as the speed increases, ex-
ceeding 72 km/h (45 mph) may
cause loss of control.

Slow down and downshift before
descending steep or long downhill
grades. Do not make sudden down-
shifts.

Avoid holding the brake pedal down
too long or too frequently. This
could cause the brakes to overheat
and result in reduced braking effi-
ciency.
Improving fuel economy is easyÐjust take
it easy. It will help make your vehicle last
longer, too. Here are some specific tips
on how to save money on both fuel and
repairs:

Keep your tires inflated at the cor-
rect pressure. Underinflation causes
tire wear and wastes fuel. See page
385 in Section 7- 2 for instructions.

Do not carry unneeded weight in
your vehicle. Excess weight puts a
heavier load on the engine, causing
greater fuel consumption.

Avoid lengthy warm- up idling. Once
the engine is running smoothly, begin
drivingÐbut gently. Remember, howev-
er, that on cold winter days this may
take a little longer.

Keep the automatic transmission
overdrive turned on when engine
braking is not required. Driving with
the overdrive off will reduce the fuel
economy. (For details, see Automatic
transmissionº on page 147 in Section
1- 7.)

Accelerate slowly and smoothly.
Avoid jackrabbit starts. Get into high
gear as quickly as possible.

Avoid long engine idling. If you have
a long wait and you are not in traffic,
it is better to turn off the engine and
start again later.

Avoid engine lugging or over- rev-
ving. Use a gear position suitable for
the road on which you are travelling.

Avoid continuous speeding up and
slowing down. Stop- and- go driving
wastes fuel.

Avoid unnecessary stopping and
braking. Maintain a steady pace. Try
to time the traffic signals so you only
need to stop as little as possible or
take advantage of through streets to
avoid traffic lights. Keep a proper dis-
tance from other vehicles to avoid sud-
den braking. This will also reduce wear
on your brakes.

Avoid heavy traffic or traffic jams
whenever possible.

Do not rest your foot on the brake
pedal. This causes premature wear,
overheating and poor fuel economy.

Maintain a moderate speed on high-
ways. The faster you drive, the greater
the fuel consumption. By reducing your
speed, you will cut down on fuel con-
sumption.

Keep the front wheels in proper
alignment. Avoid hitting the curb and
slow down on rough roads. Improper
alignment not only causes faster tire
wear but also puts an extra load on
the engine, which, in turn, wastes fuel.

Keep the bottom of your vehicle free
from mud, etc. This not only lessens
weight but also helps prevent corro-
sion.

Keep your vehicle tuned- up and in
top shape. A dirty air cleaner, improp-
er valve clearance, dirty plugs, dirty oil
and grease,brakes not adjusted, etc. all
lower engine performance and contrib-
ute to poor fuel economy. For longer
life of all parts and lower operating
costs, keep all maintenance work on
schedule, and if you often drive under
severe conditions, see that your vehicle
receives more frequent maintenance.
(For scheduled maintenance informa-
tion, please refer to the Scheduled
Maintenance Guideº or Owner 's Manu-
al Supplementº.)
CAUTION
Never turn off the engine to coast
down hills. Your power steering and
brake booster will not function with-
out the engine running. Also, the
emission control system operates
properly only when the engine is run-
ning.

6. After the engine coolant temperature
has cooled to normal, again check the
coolant level in the reservoir. If neces-
sary, bring it up to half full again. Seri-
ous coolant loss indicates a leak in the
system. You should have it checked as
soon as possible at your Toyota dealer.1. Reduce your speed gradually,
keeping a straight line. Move cau-
tiously off the road to a safe place
well away from the traffic. Avoid
stopping on the center divider of
a highway. Park on a level spot
with firm ground.
2. Stop the engine and turn on your
emergency flashers.
3. Firmly set the parking brake and
put the transmission in Pº.
4. Have everyone get out of the ve-
hicle on the side away from traffic.
5. Read the following instructions
thoroughly.CAUTION
When jacking, be sure to observe
the following to reduce the possi-
bility of personal injury:

Follow jacking instructions.

Do not put any part of your
body under the vehicle sup-
ported by the jack. Otherwise,
personal injury may occur.

Do not start or run the engine
while your vehicle is supported
by the jack.

Stop the vehicle on a level firm
ground, firmly set the parking
brake and put the transmission
in Pº. Block the wheel diago-
nally opposite to the one being
changed if necessary.
If you have a flat tireÐ

'05 HIGHLANDER_U (L/O 0409)
338
2005 HIGHLANDER from Nov. '04 Prod. (OM48570U)

Make sure to set the jack prop-
erly in the jack point. Raising
the vehicle with jack improper-
ly positioned will damage the
vehicle or may allow the ve-
hicle to fall off the jack and
cause personal injury.

Never get under the vehicle
when the vehicle is supported
by the jack alone.

Use the jack only for lifting
your vehicle during wheel
changing.

Do not raise the vehicle with
someone in the vehicle.

When raising the vehicle, do
not place any objects on top
of or underneath the jack.

Raise the vehicle only high
enough to remove and change
the tire.NOTICE
Do not continue driving with a
deflated tire. Driving even a
short distance can damage a
tire and wheel beyond repair.
