The three- way catalytic converter is an
emission control device installed in the
exhaust system.
The purpose is to reduce pollutants in the
exhaust gas.
CAUTION
Keep people and combustible mate-
rials away from the exhaust pipe
while the engine is running. The
exhaust gas is very hot.
Do not idle or park your vehicle
over anything that might burn easi-
ly such as grass, leaves, paper or
rags.
NOTICE
A large amount of unburned gasesflowing into the three- way catalyticconverter may cause it to overheatand create a fire hazard. To prevent
this and other damage, observe thefollowing precautions:
Use only unleaded gasoline.
Do not drive with an extremely lowfuel level; running out of fuel could
cause the engine to misfire, creat-ing an excessive load on the three-way catalytic converter.
Do not allow the engine to run atidle speed for more than 20 min-
utes.
Avoid racing the engine.
Do not push- start or pull- start yourvehicle.
Do not turn off the ignition while
the vehicle is moving.
Keep your engine in good runningorder. Malfunctions in the engineelectrical system, electronic ignitionsystem/distributor ignition system
or fuel systems could cause an ex-tremely high three- way catalyticconverter temperature.
If the engine becomes difficult tostart or stalls frequently, take yourvehicle in for a check- up as soon
as possible. Remember, your Toyotadealer knows your vehicle and itsthree- way catalytic converter sys-
tem best.
To ensure that the three- way cata-lytic converter and the entire emis-sion control system operate proper-ly, your vehicle must receive the
periodic inspections required by theToyota Maintenance Schedule. Forscheduled maintenance information,
refer to the Scheduled MaintenanceGuideº or Owner 's Manual Supple-mentº.

CAUTION
Avoid inhaling the engine exhaust.
It contains carbon monoxide, which
is a colorless and odorless gas. It
can cause unconsciousness or even
death.
Make sure the exhaust system has
no holes or loose connections. The
system should be checked from
time to time. If you hit something,
or notice a change in the sound of
the exhaust, have the system
checked immediately.
Do not run the engine in a garage
or enclosed area except for the
time needed to drive the vehicle in
or out. The exhaust gases cannot
escape, making this a particularly
dangerous situation.
Do not remain for a long time in a
parked vehicle with the engine run-
ning. If it is unavoidable, however,
do so only in an unconfined area
and adjust the heating or cooling
system to force outside air into the
vehicle.
To allow proper operation of your
vehicle's ventilation system, keep
the inlet grilles in front of the wind-
shield clear of snow, leaves, or oth-
er obstructions.
Keep the back door closed while
driving. An open or unsealed back
door may cause exhaust gases to
be drawn into the vehicle.
If you smell exhaust fumes in the
vehicle, drive with the windows
open and the back door closed.
Have the cause immediately located
and corrected.
FUNCTIONS OF ENGINE OIL
Engine oil has the primary functions of
lubricating and cooling the inside of the
engine, and plays a major role in main-
taining the engine in proper working order.
ENGINE OIL CONSUMPTION
It is normal that an engine should con-
sume some engine oil during normal
engine operation. The causes of oil
consumption in a normal engine are as
follows.
Oil is used to lubricate pistons, piston
rings and cylinders. A thin film of oil
is left on the cylinder wall when a pis-
ton moves downwards in the cylinder.
High negative pressure generated when
the vehicle is decelerating sucks some
of this oil into the combustion chamber.
This oil as well as some part of the oil
film left on the cylinder wall is burned
by the high temperature combustion
gases during the combustion process.
Oil is also used to lubricate the stems
of the intake valves. Some of this oil
is sucked into the combustion chamber
together with the intake air and is
burned along with the fuel. High tem-
perature exhaust gases also burn the
oil used to lubricate the exhaust valve
stems.

The amount of engine oil consumed de-
pends on the viscosity of the oil, the
quality of the oil and the conditions the
vehicle is driven under.
More oil is consumed by high- speed driv-
ing and frequent acceleration and decel-
eration.
A new engine consumes more oil, since
its pistons, piston rings and cylinder walls
have not become conditioned.
Oil consumption: Max. 1.0 L per 1000
km (1.1 qt./600 miles, 0.9 Imp. qt./600
miles)
When judging the amount of oil con-
sumption, note that the oil may become
diluted and make it difficult to judge
the true level accurately.
As an example, if a vehicle is used for
repeated short trips, and consumes a nor-
mal amount of oil, the dipstick may not
show any drop in the oil level at all, even
after 1000 km (600 miles) or more. This
is because the oil is gradually becoming
diluted with fuel or moisture, making it
appear that the oil level has not changed.
The diluting ingredients evaporate out
when the vehicle is then driven at high
speeds, as on an expressway, making it
appear that oil is excessively consumed
after driving at high speeds. IMPORTANCE OF ENGINE OIL LEVEL
CHECK
One of the most important points in prop-
er vehicle maintenance is to keep the en-
gine oil at the optimum level so that oil
function will not be impaired. Therefore, it
is essential that the oil level be checked
regularly. Toyota recommends that the oil
level be checked every time you refuel
the vehicle.
NOTICE
Failure to check the oil level regularly
could lead to serious engine troubledue to insufficient oil.
For detailed information on oil level check,
see Checking the engine oil levelº on
page 286 in Section 7- 2.
Your engine is fitted with iridium- tipped
spark plugs.
NOTICE
Use only iridium- tipped spark plugs
and do not adjust gaps for your en-gine performance and smooth drive-ability.

The tandem master cylinder brake system
is a hydraulic system with two separate
sub- systems. If either sub- system should
fail, the other will still work. However, the
pedal will be harder to press, and your
stopping distance will increase. Also, the
brake system warning light may come on.
CAUTION
Do not drive your vehicle with only a
single brake system. Have your
brakes fixed immediately.
BRAKE BOOSTER
The brake booster uses engine vacuum to
power- assist the brakes. If the engine
should quit while you are driving, you can
bring the vehicle to a stop with normal
pedal pressure. There is enough reserved
vacuum for one or two stopsÐbut no
more!
CAUTION
Do not pump the brake pedal if the
engine stalls. Each push on the
pedal uses up your reserved vacu-
um.
Even if the power assist is com-
pletely lost, the brakes will still
work. But you will have to push the
pedal hard, much harder than nor-
mal. And your braking distance will
increase.
ANTI- LOCK BRAKE SYSTEM
(with ABSº warning light)
The anti- lock brake system is designed
to help prevent lock- up of the wheels
during a sudden braking or braking on
slippery road surfaces. This assists in
providing directional stability and steer-
ing performance of the vehicle under
these circumstances.
Effective way to press the ABS brake
pedal: When the anti- lock brake system
function is in action, you may feel the
brake pedal pulsating and hear a noise.
In this situation, to let the anti- lock
brake system work for you, just hold the
brake pedal down more firmly. Do not
pump the brake in a panic stop. This
will result in reduced braking performan-
ce.
The anti- lock brake system becomes op-
erative after the vehicle has accelerated
to a speed in excess of approximately 10
km/h (6 mph). It stops operating when the
vehicle decelerates to a speed below
approximately 5 km/h (3 mph).
Depressing the brake pedal on slippery
road surfaces such as on a manhole cov-
er, a steel plate at a construction site,
joints in a bridge, etc. on a rainy day
tends to activate the anti- lock brake sys-
tem.
You may hear a click or motor sound in
the engine compartment for a few seconds
when the engine is started or just after
the vehicle begins to move. This means
that the anti- lock brake system is in the
self- check mode, and does not indicate a
malfunction.

For an explanation of this system's warn-
ing light, see Service reminder indicators
and warning buzzersº on page 109 in Sec-
tion 1- 6.
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.Your Toyota is equipped with a limited- slip
center differential (transfer). If one wheel
begins to spin, the limited- slip center dif-
ferential (transfer) is designed to aid trac-
tion by automatically transmitting driving
force to the wheels on the other drive
axle. It transmits driving force to the front
wheels if a rear wheel spins, and to the
rear wheels if a front wheel spins.
Some models are also equipped with a
limited- slip rear differential. If one rear
wheel begins to spin, the limited- slip rear
differential is designed to aid traction by
automatically transmitting driving force to
the other rear wheel. If you are not sure
whether your vehicle is equipped with one,
you can ask your Toyota dealer.
CAUTION
Do not start or run the engine while
your vehicle is supported by a jack.
The vehicle could be driven off the
jack and could pose a danger or re-
sult in serious injury.

1. Check the area around the vehicle be-fore entering it.
2. Adjust seat position, seatback angle, seat cushion angle, head restraint
height and steering wheel angle.
3. Adjust the inside and outside rear view mirrors.
4. Lock all doors.
5. Fasten seat belts. 1. Apply the parking brake firmly.
2. Turn off unnecessary lights and acces-
sories.
3. Manual transmission: Press the clutch
pedal to the floor and shift the trans-
mission into neutral. Hold the clutch
pedal to the floor until the engine is
started. A starter safety device will pre-
vent the starter from operating if the
clutch pedal is not fully depressed.
Automatic transmission: Put the se-
lector lever in Pº. If you need to re-
start the engine while the vehicle is
moving, put the selector lever in Nº.
A starter safety device will prevent the
starter from operating if the selector
lever is in any drive position.
4. Automatic transmission only: De-
press the brake pedal and hold it to
the floor until driving off. Before starting the engine, be sure to fol-
low the instructions in (a) Before crank-
ingº.
Normal starting procedure
The multiport fuel injection system/sequen-
tial multiport fuel injection system in your
engine automatically controls the proper
air- fuel mixture for starting. You can start
a cold or hot engine as follows:
With your foot off the accelerator pedal,
crank the engine by turning the key to
STARTº. Release it when the engine
starts.
Engine should be warmed up by driving,
not in idle. For warming up, drive with
smoothly turning engine until engine cool-
ant temperature is within normal range.
If the engine stalls...
Simply restart it, using the correct proce-
dure given in normal starting.
If the engine will not start...
See If your vehicle will not startº on page
242 in Section 4.

NOTICE
Do not crank for more than 30 se-conds at a time. This may overheatthe starter and wiring systems.
Do not race a cold engine.
If the engine becomes difficult tostart or stalls frequently, have the
engine checked immediately.
Always slow down in gusty crosswinds.
This will allow you much better control.
Drive 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 a bumpy r oad. Other-
wise the impact could cause severe
damage to the tires and/or wheels.
When 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 Pº (automatic) or in first or
reverse (manual). If necessary, block
the wheels.
Washing 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 a Toyota dealer for assistance.
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.

2005 RAV4 from Sep. '04 Prod. (OM42570U)
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 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.
When driving your vehicle off- road, please
observe the following precautions to en-
sure your driving enjoyment and to help
prevent the closure of areas to off- road
vehicles.a. Drive your vehicle only in areas where off- road vehicles are permitted to trav-
el.
b. Respect private property. Get owner 's permission before entering private prop-
erty.
c. Do not enter areas that are closed. Honor gates, barriers and signs that re-
strict travel.
d. Stay on established roads. When condi- tions are wet, driving techniques should
be changed or travel delayed to pre-
vent damage to roads.
For owners in U.S. mainland, Hawaii and
Puerto Rico:
To obtain additional information pertaining
to driving your vehicle off- road, consult
the following organizations.
State and Local Parks and Recreation
Departments
State Motor Vehicle Bureau
Recreational Vehicle Clubs
U.S. Forest Service and Bureau of
Land Management
CAUTION
Always observe the following precau-
tions to minimize the risk of serious
personal injury or damage to your ve-
hicle:
Drive carefully when off the road.
Do not take unnecessary risks by
driving in dangerous places.
Do not grip the steering wheel
spokes when driving off- road. A
bad bump could jerk the wheel and
injure your hands. Keep both hands
and especially your thumbs on the
outside of the rim.
Always check your brakes for effec-
tiveness immediately after driving in
sand, mud, water or snow.
After driving through tall grass,
mud, rock, sand, rivers, etc., check
that there is no grass, bush, paper,
rags, stone, sand, etc. adhering or
trapped on the underbody. Clear off
any such matter from the under-
body. If the vehicle is used with
these materials trapped or adhering
to the underbody, a breakdown or
fire could occur.

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 aswhen crossing shallow streams,first check the depth of the waterand the bottom of the river bed for
firmness. Drive slowly and avoiddeep water.
Take all necessary safety measures
to ensure that water damage to theengine or other components doesnot occur.
Water entering the engine air intakewill cause severe engine damage.
Water can wash the grease fromwheel bearings, causing rusting andpremature failure, and may also en-
ter the differentials, transmissionand transfer case, reducing the gearoil's lubricating qualities.
Sand and mud that has accumulatedin brake drums and around brake
discs may affect braking efficiencyand may damage brake system com-ponents.
Always perform a maintenance in-spection after each day of off- roaddriving 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 ManualSupplementº.
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 288 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 -35 C
(- 31 F).
For CanadaÐToyota Super Long Life
Coolantº is a mixture of 55% coolant and
45% deionized water. This coolant pro-
vides protection down to about -42 C
(- 44 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 starting.
Section 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 page 286 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.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 (automatic) or into first or reverse
(manual) and block the rear 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.
