The gauge indicates the engine coolant 
temperature when the ignition switch is 
on. The engine operating temperature 
will vary with changes in weather and
engine load. 
If the needle points to the red zone or 
higher, stop your vehicle and allow the 
engine to cool. 
Your vehicle may overheat during severe 
operating conditions, such as:   Driving up a long hill on a hot day.
  Reducing speed or stopping after high 
speed driving.
  Idling for a long period with the air
conditioning on in stop- and- go traffic.
  Towing a trailer.
NOTICE
 Do not remove the thermostat in
the engine cooling system as thismay cause the engine to overheat.The thermostat is designed to con-
trol the flow of coolant to keep thetemperature of the engine withinthe specified operating range.
 Do not  continue driving with anoverheated engine. See ºIf your ve-hicle overheatsº in Part 4.
Oil pressure gauge
Idling
Normal driving
The oil pressure gauge indicates engine 
oil pressure when the ignition switch is 
on. Check it while driving to make sure 
that the needle is in the proper range. 
If the oil pressure should stay below the 
normal range, pull off the road to a safe
place and stop the engine immediately. 
Call a Toyota dealer or qualified repair 
shop for assistance. 
Oil pressure may not build up when the 
oil level is too low. The oil pressure 
gauge is not designed to indicate oil level,
and the oil level must be checked using 
the level dipstick.

NOTICE
Do not drive the vehicle with the oilpressure below the normal range untilthe cause is fixedÐit may ruin theengine.
Vo l t m e t e r
The voltmeter tells whether the battery 
is charged or discharged. Check it 
while the engine is runningÐthe needle 
should always indicate as shown above. 
If the needle reads below or above the 
normal range while the engine is running,
it indicates the charging system needs im- 
mediate repair. 
However, it is normal for the needle to 
drop below the normal range during en- 
gine starting. TachometerThe tachometer indicates engine speed 
in thousands of rpm (revolutions per 
minute). Use it while driving  to select 
correct shift points and to prevent en-
gine lugging and overrevving. 
Driving with the engine running too fast 
causes excessive engine wear  and poor 
fuel economy. Remember, in most cases 
the slower the engine speed, the greater
the fuel economy.
NOTICE
Do not let the indicator needle get
into the red zone. This may causesevere engine damage.

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. 
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.

Brake system 
BRAKE SYSTEM 
This brake system has  two independent 
hydraulic circuits. If either circuit should 
fail, the other will still work. However, 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 brake  fluid pres- 
surized by the pump to power- assist the 
brakes. If the brake booster fails during
driving, the brake system warning light 
comes on and buzzer  sound continuously. 
In this case the brakes may not work
properly. If they do not work well, depress 
the brake pedal firmly. If the brake system 
warning light comes on, immediately stop
your vehicle and  contact  your  Toyota deal- 
er.
