utes of checking can help ensure safe and
pleasant driving. Just a basic familiarity
with your vehicle is required and a careful
eye! Or, if you would like, any authorized
Toyota dealer or repairer, or another duly
qualified and equipped professional, will
be pleased to make this check for you at
a nominal cost.
CAUTION
If you make this check in an enclosed
garage, make sure there is adequate
ventilation. Engine exhaust is poison-
ous.
BEFORE STARTING THE ENGINE

STARTING AND DRIVING135
Instruments and controls.Especially
make sure the service reminder indicators,
instrument lights, and defroster are work-
ing.
Brakes.Make sure the pedal has enough
clearance.
Spare fuses.Make sure you have spare
fuses. They should cover all the amperage
ratings designated on the fuse box lid.
In the engine compartment
Coolant level.Make sure the coolant lev-
el is correct. (See page 198 in Section
7−2 for instructions.)
Wiring.Look for damaged, loose, or dis-
connected wires.
Fuel lines.Check the lines for leaks or
loose connections.
AFTER STARTING THE ENGINE
Exhaust system.If you notice any
change in the sound of the exhaust or
smell exhaust fumes, have the cause lo-
cated and corrected immediately. (See
“Engine exhaust cautions” on page 122 in
Section 2.)
Engine oil level.Stop the engine and
check the dipstick with the vehicle parked
on a level spot. (See page 196 in Section
7−2 for instructions.)
WHILE DRIVING
Instruments.Make sure the speedometer
and gauges are working.
Brakes.In a safe place, check that the
brakes do not pull to one side when ap-
plied.
Anything unusual?Look for loose parts
and leaks. Listen for abnormal noises.
If everything looks O.K., set your mind at
ease and enjoy your trip!DAlways slow down in gusty crosswinds.
This will allow you much better control.
DDrive slowly onto curbs and, if pos-
sible, at a right angle. Avoid driving
onto high, sharp−edged objects and
other road hazards. Failure to do so
can lead to severe tire damage such
as a tire burst.
Drive slowly when passing over bumps
or travelling on abumpy road. Other-
wise, the impact could cause severe
damage to the tires and/or wheels.
DWhen parking on a hill, turn the front
wheels until they touch the curb so
that the vehicle will not roll. Apply the
parking brake, and place the transmis-
sion in first or reverse. If necessary,
block the wheels.
DWashing your vehicle or driving through
deep water may get the brakes wet. To
see whether they are wet, check that
there is no traffic near you, and then
press the pedal lightly. If you do not
feel a normal braking force, the brakes
are probably wet. To dry them, drive
the vehicle cautiously while lightly
pressing the brake pedal with the park-
ing brake applied. If they still do not
work safely, pull to the side of the road
and call any authorized Toyota dealer
or repairer, or another duly qualified
and equipped professional, for assis-
tance.
CAUTION
DBefore driving off, make sure the
parking brake is fully released and
the parking brake reminder light is
off.
DDo not leave your vehicle unat-
tended while the engine is running.
DDo not rest your foot on the brake
pedal while driving. It can cause
dangerous overheating, needless
wear, and poor fuel economy.

Tips for driving in various
conditions

STARTING AND DRIVING137
When encountering flooded roads
Do not drive on a road that has flooded
after heavy rain etc. Doing so may cause
serious damage to the vehicle.
NOTICE
Driving on a flooded road may cause
the engine to stall as well as cause
serious vehicle malfunctions such as
shorts in electrical components and
engine damage from water immersion.
In the event that you drive on a
flooded road and the vehicle is
flooded, be sure to have any autho-
rized Toyota dealer or repairer, or
another duly qualified and equipped
professional check brake function,
changes in quantity and quality of oil
and fluid used for the engine, trans-
mission, differential, etc. and lubricant
condition for the propeller shaft, bear-
ings and suspension joints (where
possible) and the function of all joints
and bearings.
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 198 in Section 7−2 for details of
coolant type selection.
“Toyota Super Long Life Coolant” is a mix-
ture of 50% coolant and 50% deionized
water. This coolant provides protection
down to about−35_C(−31_F).
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. Any authorized Toyota
dealer or repairer, or another duly quali-
fied and equipped professional, will be
pleased to check the level of charge.
Make sure the engine oil viscosity is
suitable for the cold weather.
See page 196 in Section 7−2forrecom-
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
any authorized Toyota dealer or repairer,
or another duly qualified and equipped
professional—who will be pleased to help.

Winter driving tips

138STARTING AND DRIVING
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
inserting it.
Use a washer fluid containing an anti-
freeze solution.
This product is available at any authorized
Toyota dealer or repairer and most auto
parts stores or another qualified professio-
nal. 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
first or reverse and block the front
wheels. Do not use the parking brake, or
snow or water accumulated 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 designed primarily as a
passenger−and−load−carrying vehicle. Tow-
ing a trailer will have an adverse effect on
handling, 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. Ask your
local authorized Toyota dealer or repairer,
or another duly qualified and equipped
professional, for further details before tow-
ing, as there are additional legal require-
ments in some countries.
WEIGHT LIMITS
Before towing, confirm the towing capacity,
gross vehicle mass (GVM), maximum per-
missible axle capacity (MPAC) and draw-
bar load. They are listed on page 222 in
Section 8.
When towing a trailer, observe the follow-
ing:
DThe total trailer weight (trailer weight
plus its cargo load) is within the towing
capacity.
DWhen the total trailer weight is greater
than the vehicle weight, we recommend
the use of a friction stabilizer (sway
control device).
DWhen the total trailer weight is over
2000 kg (4409 lb.), a friction stabilizer
(sway control device) is required.

Trailer towing

144STARTING AND DRIVING
TIRES
DEnsure that your vehicle’s tires are
properly inflated. See page 201 in Sec-
tion 7−2 and page 226 in Section 8 for
instructions.
DThe trailer tires should be inflated to
the pressure recommended by the trail-
er manufacturer in respect to the total
trailer weight.
TRAILER LIGHTS
DCheck 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
DToyota 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
DIf you tow a trailer, your vehicle will
require more frequent maintenance due
to the additional load.
DRetighten all fixing bolts of the towing
ball and bracket after approximately
1000 km (600 miles) of trailer driving.
PRE−TOWING SAFETY CHECK
DBe sure not to exceed designated max-
imum load for the ball coupling of the
towing bracket. Please remember that
the ball coupling load will increase the
load on the vehicle. Maximum permissi-
ble rear axle capacity must not be ex-
ceeded.
DMake sure the trailer cargo is securely
loaded so that it cannot shift.
DIf the traffic behind the trailer cannot
be seen properly with the standard rear
view mirrors, additional outside mirrors
will be necessary. Both outside mirrors
must be fitted on folding arms and ad-
justed to give a good rear view at all
times.
TRAILER TOWING TIPS
Your vehicle will handle differently
when towing a trailer. In order to avoid
accident, death or serious injury, keep
the following in mind when towing:
DBefore 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.
DBecause stopping distance may be in-
creased, vehicle−to−vehicle distance
should be increased when towing a
trailer. For each 10 km/h (6 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.
DAvoid jerky starts or sudden accelera-
tion. Prevent excessive clutch slippage
by keeping engine rpm low and not
racing the engine. Always start out in
first gear.
DAvoid 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.

150IN CASE OF AN EMERGENCY
Before making these checks, make sure
you have followed the correct starting pro-
cedure given in “How to start the engine”
on page 132 in Section 3 and that you
have sufficient fuel.
If the engine is not turning over or is
turning over too slowly—
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 discharged. You may try jump start-
ing. See “(c) Jump starting” on page
151 for further instructions.
If the light is O.K., but the engine still will
not start, it needs adjustment or repair.
Call any authorized Toyota dealer or re-
pairer, or another duly qualified and
equipped professional.
NOTICE
Do not pull−or push−start the ve-
hicle. It may damage the vehicle or
cause a collision when the engine
starts. Also, the catalytic converter
may overheat and become a fire haz-
ard.
If the engine turns over at its normal
speed but will not start—
1. If you are starting the engine that has
died from an empty tank, you may
have needed to bleed the fuelsystem
before cranking the engine. See “(b)
Bleeding the fuelsystem” onpage 150
for further instructions.
2. If the fuel system is O.K., but the
engine still will not start, it needs ad-
justment or repair. Call any authorized
Toyota dealer or repairer, or another
duly qualified and equipped profession-
al, for assistance.
If you run out of fuel and the engine
dies, the engine may not restart after
refueling. In such case, operate the
priming pump until you feel more resis-
tance.

Connecting point
Do not connect the cable to or near
any part that moves when the engine
is cranked.
CAUTION
When making the connections, to
avoid death or serious injury, do not
lean over the battery or accidentally
let the jumper cables or clamps touch
anything except the correct battery
terminals or the ground.
5. Charge the discharged battery with the
jumper cable connected for approxi-
mately 5 minutes. At this time, run the
engine in the vehicle with the booster
battery at about 2000 rpm with the ac-
celerator pedal lightly depressed.
6. Start your engine in the normal way.
After starting, run it at about 2000 rpm
for several minutes with the accelerator
pedal lightly depressed.
7. Carefully disconnect the cables in the
exact reverse order: the negative cable
and then the positive cable.
8. If your vehicle is equipped with the
battery cover, install it.If the cause of your battery discharging is
not apparent (for example, lights left on),
you should have it checked at any autho-
rized Toyota dealer or repairer, or another
duly qualified and equipped professional.
If the first start attempt is not success-
ful...
Check that the clamp on the jumper
cables are tight. Recharge the discharged
battery with the jumper cables connected
for several minutes and restart your en-
gine in the normal way.
If the another attempt is not successful,
the battery may be depleted. Have it ch-
ecked at any authorized Toyota dealer or
repairer, or another duly qualified and
equipped professional.

156IN CASE OF AN EMERGENCY
If your engine coolant temperature
gauge indicates overheating, if you ex-
perience a loss of power, or if you hear
a loud knocking or pinging noise, the
engine has probably overheated. You
should follow this procedure...
1. Pull safely off the road, stop the ve-
hicle, and turn on your emergency
flashers. Put the transmission in neu-
tral and apply the parking 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 engine access hole cover
or tilting the cab. If there is no coolant
or steam boiling over, leave the engine
running and make sure the electric
cooling fan is operating. If it is not,
turn the engine switch off.
CAUTION
To help avoid serious injury, keep the
engine access hole cover closed or
the cab lowered until there is no
steam. Escaping steam or coolant is
a sign of very high pressure.
3. Visually check to see if the engine
drive belt (fan belt) is broken or loose.
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.
CAUTION
When the engine is running, keep
hands and clothing away from the
moving fan and engine drive belts.
4. If the engine drive belt is broken or the
coolant is leaking, stop the engine im-
mediately. Call any authorized Toyota
dealer or repairer, or another duly qual-
ified and equipped professional, for as-
sistance.
5. If the engine drive belt is O.K. and
there are no obvious leaks, you may
help the engine cool down more quickly
by running it at about 1500 rpm for a
few minutes with the accelerator pedal
lightly depressed.
6. Check the coolant reservoir. If it is dry,
add coolant to the reservoir while the
engine is running. Fill it about half full.
For the coolant type, see “Coolant type
selection” on page 199 in Section 7−2.
CAUTION
Do not attempt to remove the radiator
cap when the engine and radiator are
hot. Serious injury could result from
scalding hot fluid and steam blown
out under pressure.
7. 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.
Serious coolant loss indicates a leak in
the system. You should have it
checked as soon as possible at any
authorized Toyota dealer or repairer, or
another duly qualified and equipped
professional.
