CAUTION

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

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

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 ac-
celeration 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 lon-
ger stopping distance, and it may
pull to one side when the brakes are
applied. Also, the parking brake
will not hold the vehicle securely. Make sure you have ethylene-glycol
antifreeze in the radiator.
Do not use alcohol type antifreeze.
NOTICE
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 starting.
Chapter 7-3 tells you how to visually in-
spect 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 Chapter 7-2 for recommended vis-
cosity.
Leaving a heavy summer oil in your
vehicle during winter months may cause
harder starting. If you are not sure about
which oil to use, call your Toyota dealerÐ
he 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. To open
a frozen lock, try heating the key before in-
serting it.
Winter driving tips
ProCarManuals.com

128Use 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.
Do not use engine antifreeze or any
other substitute because it may
damage your vehicle's paint.
NOTICE
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 ve-
hicle are tire chains, window scraper, bag
of sand or salt, flares, small shovel, jump-
er cables, etc.
Your vehicle is designed primarily as a
passenger-carrying vehicle. Towing a
trailer will have an adverse effect on han-
dling, performance, braking, durability
and driving economy (fuel consumption,
etc.). Your safety and satisfaction
depend
on the proper use of correct equipment
and cautious driving habits. For your safe-
ty and the safety of others, you must not
overload your vehicle or trailer. Toyota
warranties do not apply to damage or mal-
function caused by towing a tailer for com-
mercial purposes. Ask your local Toyota
dealer for further details before towing.
WEIGHT LIMITS
Before towing, make sure the total trailer
weight, gross vehicle weight, gross axle
weight and trailer tongue load are all with-
in the limits.
The total trailer weight and tongue load
can be measured with platform scales
found at a highway weighing station,
building supply company, trucking com-
pany, junk yard, etc.
CAUTION

The total trailer weight (trailer
weight plus its cargo load) must
not exceed 907 kg (2000 lb.). Ex-
ceeding this weight is dangerous.!
Trailer towing
ProCarManuals.com

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.

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, ex-
cessive speed and improper trailer
loading. Keep these in mind when tow-
ing:

Before starting out, check operation of
the lights and all vehicle-trailer con-
nections. After driving a short dis-
tance, stop and recheck the lights and
connections. Before actually towing a
trailer, practice turning, stopping and
backing with a trailer in an area away
from traffic until you learn the feel.

Backing w ith a trailer is difficult and re-
quires 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 procedure
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 back-
ing to reduce the risk of an accident.

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 prepare
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 ef-
ficiency 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
305C [85 5 F]) 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 in Part 4 of
this manual.ProCarManuals.com

Before making these checks, make sure
you have followed the correct starting pro-
cedure given in How to start the engineº
in Part 3 and that you have sufficient fuel.
If the engine is not turning over or is
turning over too slowlyÐ
1. Check that the battery terminals are
tight and clean.
2. If the battery terminals are O.K., switch
on the interior light.
3. If the light is out, dim or goes out when
the starter is cranked, the battery is dis-
charged. You may try jump starting. See
(c) Jump startingº for further instructions.
If the light is O.K., but the engine still will
not start, it needs adjustment or repair.
Call a Toyota dealer or qualified repair
shop.
NOTICE
Do not pull- or push-start the vehicle. It may damage the vehicle
or cause a collision when the enginestarts. Also the three-way catalyticconverter may overheat andbecome a fire hazard.
If the engine turns over at its normal
speed but will not startÐ
1. Check that all the push-on connectors
are tight. (For example, connectors at the
spark plugs)
2. If the connectors are O.K., the engine
may be flooded because of repeated
cranking. See (b) Starting a flooded en-
gineº for further instructions.
If your vehicle will not startÐ

1385. Start your engine in the normal way.
After starting, run it at about 2000 rpm for
several minutes with the accelerator ped-
al lightly depressed.
6. Carefully disconnect the cables in the
exact reverse order: the negative cable
and then the positive cable.
7. Carefully dispose of the battery cover
clothsÐthey may now contain sulfuric
acid.
8. If removed, replace all the battery vent
plugs.
If the cause of your battery discharging is
not apparent (for example, lights left on),
you should have it checked.
If your engine stalls while driving
0
1. Reduce your speed gradually, keeping
a straight line. Move cautiously off the
road to a safe place.
2. Turn on your emergency flashers.
3. Try starting the engine again.
If the engine will not start, see If your ve-
hicle will not startº.
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. CAUTION
!
If your engine coolant temperature
gauge indicates overheating, if you
experience a loss of power, or if you
hear a loud knocking or pinging noise,
the engine has probably overheated.
You should follow this procedure
0
1. Pull safely off the road, stop the vehicle
and turn on your emergency flashers. Put
the transmission in Pº and apply the park-
ing brake. Turn off the air conditioning if it
is being used.
2. If coolant or steam is boiling out of the
radiator or reservoir, stop the engine. Wait
until the steam subsides before opening
the hood. If there is no coolant boiling over
or steam, leave the engine running and
make sure the electric cooling fan is oper-
ating. If it is not, turn the ignition off.
To help avoid personal injury, keep
the hood closed until there is no
steam. Escaping steam or coolant is
a sign of very high pressure. CAUTION
!
3. Look for obvious coolant leaks from
the radiator, hoses, and under the vehicle.
However, note that water draining from
the air conditioning is normal if it has been
used.

When the engine is running, keep
hands and clothing away from the
moving fan and engine drive belts.CAUTION
!
4. If the coolant is leaking, stop the en-
gine immediately.
Call a Toyota dealer for
assistance.
5. If there are no obvious leaks, check the
coolant reservoir. If it is dry, add coolant to
the reservoir while the engine is running.
Fill it about half full.
Do not attempt to remove the radia-
tor cap when the engine and radia-
tor are hot. Serious injury could re-
sult from scalding hot fluid and
steam blown out under pressure. CAUTION
!
6. After the engine coolant temperature
has cooled to normal, again check the
coolant
level in the reservoir. If necessary,
bring it up to half full again. Serious
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 cautiously off the
road to a safe place well away from the
traffic. Avoid stopping on the center divid-
er of a highway. Park on a level spot with
firm ground.
2. Stop the engine and turn on your emer-
gency flashers.
3. Firmly set the parking brake and put
the transmission in Pº.
4. Have everyone get out of the vehicle
on the side away from traffic.
5. Read the following instructions thor-
oughly.
When jacking, be sure to observe
the following to reduce the
possibility of personal injury:

Follow jacking instructions.

Use a jack only for lifting your ve-
hicle during wheel changing.

Never get beneath the vehicle
when supported by a jack.

Do not start or run the engine
while your vehicle is supported
by the jack. CAUTION
!
NOTICE
Do not continue driving with a deflated tire. Driving even a short
distance can damage a tire beyondrepair.

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.

158Where to go for service?
Toyota technicians are well-trained spe-
cialists
and are kept up to date with the lat-
est service information through technical
bulletins, service tips, and in-dealership
training programs. They learn to work on
Toyotas before they work on your vehicle,
rather than while they are working on it.
You can be confident that your Toyota
dealer's service department performs the
best job to meet the maintenance require-
ments on your vehicleÐreliably and eco-
nomically.
Your copy of the repair order is proof that
all required maintenance has been per-
formed for warranty coverage. And if any
problems should arise with your vehicle
while under warranty, your Toyota dealer
will promptly take care of it. Again, be sure
to keep a copy of the repair order for any
service performed on your Toyota.
What about do-it-yourself mainte-
nance?
Many of the maintenance items are easy
to do yourself if you have a little mechani-
cal ability and a few basic automotive
tools. Simple instructions for how to per-
form them are presented in Part 7. If you are a skilled do-it-yourself me-
chanic, the Toyota service manuals are
recommended. Please be aware that do-
it-yourself maintenance can affect your
warranty coverage. See Owner's Guide,
Owner 's
Manual Supplement or W arranty
Booklet for the details. Listed
below are the general maintenance
items that should be performed as fre-
quently as specified. In addition to check-
ing the items listed, if you notice any un-
usual noise, smell or vibration, you should
investigate the cause or take your vehicle
to your T oyota dealer or a qualified service
shop immediately. It is recommended that
any problem you notice be brought to the
attention of your dealer or the qualified
service shop for their advice.
Make these checks only where
adequate ventilation can be ob-
tained if you run the engine. CAUTION
!
OUTSIDE THE VEHICLE
Items listed below should be per-
formed from time to time, unless
otherwise specified.
