TESTING THE SYSTEM
1. Open all the windows
2. Set the system as described above.
The doors should be locked with the key
or wireless remote control transmitter. Be
sure to wait until the indicator light starts
flashing.
3. Unlock any door from the inside. The
system should activate the alarm.
4. Cancel the system by unlocking any
of the doors with the key or wireless re-
mote control transmitter.
5. Repeart this operation for the other
doors, trunk and hood. When testing on
the hood, also check that the system is ac-
tivated when the battery terminal is dis-
connected and then reconnected.
If the system does not work properly, have
it checked by your Toyota dealer.
1. To open the fuel filler door, pull thelever up.
CAUTION!

Do not smoke, cause sparks or al-
low open flames when refuelling.
The fumes are flammable.

When opening the cap, do not re-
move the cap quickly. In hot
weather, fuel under pressure
could cause injury by spraying
out of the filler neck if the cap is
suddenly removed.
2. To remove the fuel tank cap, turn
the cap slowly counterclockwise,
then pause slightly before remov-
ing it. After removing the cap, hang
it on the cap hanger.
It is not unusual to hear a slight swoosh
when the cap is opened. When installing,
turn the cap clockwise till you hear a click.
If the cap is not tightened securely, the
malfunction indicator lamp comes on.
Make sure the cap is tightened securely.
The indicator lamp goes off after driving
several times. If the indicator lamp does
not go off, contact your Toyota dealer as
soon as possible.

Keep the trunk lid closed while
driving. An open or unsealed
trunk lid may cause exhaust
gases to be drawn into the ve-
hicle. If you must drive with the
trunk lid open to accommodate a
large object, close the windows,
open all the instrument panel
vents and have the heating or
cooling system deliver fresh air
into the vehicle by turning the fan
to high speed with the air intake
control button set at the outside
air mode.

To allow proper operation of your
vehicle's ventilation system, keep
the inlet grilles in front of the
windshield clear of snow, leaves,
or other obstructions.

If you smell exhaust fumes in the
vehicle, drive with the windows
open and the trunk lid closed.
Have the cause immediately lo-
cated and corrected. FUNCTIONS OF ENGINE OIL
Engine oil has the primary functions of lu-
bricating and cooling the inside of the en-
gine,
and plays a major role in maintaining
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 piston
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 com-
bustion 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 cham-
ber 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.
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 re-
peated 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 the fuel or moisture, making it
appear that the oil level has not changed.
Facts about engine oil
consumption
ProCarManuals.com

134The 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 as high speeds.
IMPORTANCE OF ENGINE OIL LEVEL
CHECK
One of the most important points in proper
vehicle maintenance is to keep the engine
oil at the optimum level so that oil function
will
not be impaired. Therefore, it is essen-
tial that the oil level be checked regularly.
Toyota recommends that the oil level be
checked every time you refuel the vehicle.
Failure to check the oil level
regularly could lead to serious
engine trouble due to insufficientoil.
NOTICE
For detailed information on the oil level
check, see Checking the engine oil levelº
in Chapter 7-2.
Your engine is fitted with twin ground elec-
trode spark plugs.
Use only twin ground electrode
spark plugs for your engine
performance.
NOTICE
TANDEM MASTER CYLINDER BRAKE
SYSTEM
The tandem master cylinder brake sys-
tem is a hydraulic system with two sepa-
rate sub-systems. If either sub-system
should fail, the other w ill still work. Howev-
er, the pedal will be harder to press, and
your stopping distance will be longer.
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 reserve
vacuum for one or two stopsÐbut no
more!

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

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

Avoid holding the pedal down too
long or too frequently. This could
cause the brakes to overheat and
result in reduced braking
efficiency.
CAUTION!
Getting more kilometers/mileage from a li-
ter/gallon of fuel is easy-just 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 Chapter
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 lenghty warm-up idling.
Once the engine is running smoothly,
begin drivingÐbut gently. Remember,
however, that on cold winter days this
may take a little longer.

Accelerate slowly and smoothly.
Avoid jackrabbit starts.

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 lug or overrevving.
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 distance
from other vehicles to avoid sudden
braking. This will also reduce wear on
your brakes.

Avoid heavy traffic or traffic jams
whenever possible.

Do not rest your foot on the clutch
or brake pedal. This causes needless
wear, overheating and poor fuel econ-
omy.

Maintain a moderate speed on
highways. The faster you drive, the
greater the fuel consumption. By re-
ducing your speed, you will cut down
on fuel consumption.

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 your tire pressures at the proper
level.
The recommended cold tire pressures,
tire size and the vehicle capacity weight
are also given in Part 8. They are also on
the tire pressure label as shown.
You should check the tire pressures every
two weeks, or at least once a month. And
don't forget the spare!
Incorrect tire pressure can reduce tire
life and make your vehicle less safe to
drive.Low tire pressure results in excessive
wear, poor handling, reduced fuel econo-
my, and the possibility of blowouts from
overheated tires. Also, low tire pressure
can cause poor sealing of the tire bead.
If the tire pressure is excessively low,
there is the possibility of wheel deforma-
tion and/or tire separation.
High tire pressure produces a harsh ride,
handling problems, excessive wear at the
center of the tire tread, and a greater
pos-
sibility of tire damage from road hazards.
If a tire frequently needs refilling, have it
checked by your Toyota dealer.
The following instructions for check-
ing tire pressure should be observed:

The pressure should be checked
only when the tires are cold. If your
vehicle has been parked for at least 3
hours and has not been driven for
more than 1.5 km or 1 mile since, you
will get an accurate cold tire pressure
reading.

Always use a tire pressure gauge.
The appearance of a tire can be mis-
leading. Besides, tire pressure that
are even just a few pounds off can de-
grade handling and ride.

Do not bleed or reduce tire pres-
sure after driving. It is normal for the
tire pressure to be higher after driving.

Never exceed the vehicle capacity
weight. The passenger and luggage
weight should be located so that the
vehicle is balanced.

Be sure to reinstall the tire inflation
valve caps. Without the valve caps,
dirt or moisture could get into the valve
core and cause air leakage. If the caps
have been lost, have new ones put on
as soon as possible.
