Break±in period
Drive gently and avoid high speeds.
Your vehicle does not need an elaborate
break±in. But following a few simple tips
for the first 1600 km (1000 miles) can add
to the future economy and long life of
your vehicle:
Do not drive over 88 km/h (55 mph).
Run the engine at moderate speed be-
tween 2000 and 4000 rpm.
Avoid full±throttle starts.
Try to avoid hard stops during the first
300 km (200 miles).
Do not drive slowly with the manual
transmission in a high gear.
Do not drive for a long time at any
single speed, either fast or slow.
Do not tow a trailer during the first 800
km (500 miles).
Fuel
FUEL TYPE
Your new vehicle must use only un-
leaded gasoline.
To help prevent gas station mix±ups, your
Toyota has a new smaller fuel tank open-
ing. The special nozzle on pumps with
unleaded fuel will fit it, but the larger
standard nozzle on pumps with leaded gas
will not.
At a minimum, the gasoline you use
should meet the specifications of ASTM
D4814 in the U.S.A. and CGSB 3.5±M93
in Canada.
NOTICE
Do not use leaded gasoline. Use of
leaded gasoline will cause the three±
way catalytic converter to lose its ef-
fectiveness and the emission control
system to function improperly. Also,
this can increase maintenance costs.

Your engine is fitted with twin ground
electrode platinum±tipped spark plugs.
NOTICE
Use only twin ground electrode plati-
num±tipped spark plugs for your en-
gine performance.
Brake system
TANDEM MASTER CYLINDER BRAKE
SYSTEM
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 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!
CAUTION
Do not pump the brake pedal if the
engine stalls. Each push on the
pedal uses up your vacuum reserve.
Even if the power assist is com-
pletely lost, the brakes will still
work. But you will have to push the
pedal hardÐmuch harder than nor-
mal. And your braking distance will
be longer.
ANTI±LOCK BRAKE SYSTEM (with
ºABSº warning light)
The anti±lock brake system is designed to
automatically help prevent lock±up of the
wheels during sudden braking or braking
on slippery road surfaces. This assists in
providing directional stability and steering
performance of the vehicle under these
circumstances.
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 decelerate to a speed below
approximately 5 km/h (3 mph).

IN CASE OF AN
EMERGENCY
If your vehicle will not start
If your engine stalls while
driving
If your vehicle overheats
If you have a flat tire
If your vehicle needs to be
towed
If you cannot shift automatic
transmission selector lever
If you lose your keys
If you lose your wireless remote
control transmitter
Before making these checks, make sure
you have followed the correct starting pro-
cedure given in ºHow to start the engineº
in Part 3 and that you have sufficient fuel.
If your vehicle is equipped with the engine
immobiliser system, also check whether
the other keys will start the engine. If
they work, your key may be broken. Have
the key checked at your Toyota dealer. If
none of your keys work, the system is
possibly broken. Call your Toyota dealer.
(See ºKeys (with engine immobiliser sys-
tem)º in Chapter 1±2.)
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 discharged. You may try jump start-
ing. See º(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 ve-
hicle. It may damage the vehicle or
cause a collision when the engine
starts. Also the three±way catalytic
converter may overheat and become 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, ignition coil and/or dis-
tributor)
2. If the connectors are O.K., the engine
may be flooded because of repeated
cranking. See º(b) Starting a flooded
engineº for further instructions.

NEW FEATURES Ð 5S-FNE ENGINE 8
FEATURES OF 5S-FNE ENGINE
Features of the 5S-FNE engine are listed below.
Item
Features
Performance
wHigh compression ratio is used.
wHigh lift camshaft is used.
wLow back pressure muffler is used.
Fuel Economy
wHigh compression ratio is used.
wValve spring load has been reduced.
wLow-friction, TiN (titanium nitride) coated valve lifters has been
adopted.
Low Emission
wA fuel injection system containing gas injectors has been adopted.
wBecause the fuel is in the gaseous state, it does not come in contact with
the wall surface, making optimal air-fuel ratio control possible immedi-
ately after the engine has been started.
wPrecision air-fuel ratio feedback control that uses an air-fuel ratio sensor
and a heated oxygen sensor has been adopted.
wTwo catalytic converters designed exclusively for the natural gas engine
have been adopted: the WU-TWC (Warm Up Three-Way Catalytic Con-
verter) and the TWC (Three-Way Catalytic Converter).
Other Features
wHighly rigid pistons have been adopted to accommodate the high com-
pression ratio.
wA CNG (Compressed Natural Gas) pressure regulator that precisely reg-
ulates the CNG has been adopted.
wA large-bore delivery pipe and fuel hose with minimal internal conduit
resistance have been adopted.
wThe electro magnetic fuel shut off valve is added on the delivery pipe.
wA fuel pressure sensor that corrects the fuel injection volume and a fuel
temperature sensor have been provided on the delivery pipe.
wThe starting performance of the engine at low temperatures has been en-
sured by increasing the volume of the airflow of the IAC (Idle Air Con-
trol).
wMaterials that excel in wear resistance have been adopted on the valves
and valve seats for both the intake and exhaust.
wRust-resistant spark plugs have been adopted.
wAluminum lining and carbon fiber have been adopted in the fuel tank.
wFor the fuel gauge, a fuel tank fuel temperature sensor and a fuel pipe fuel
pressure sensor have been adopted.

10. Fuel Temperatur and Pressure Sensor for Fuel Gage
A fuel temperature sensor that detects the temperature in the fuel tank is provided on the tank valve assembly.
A fuel pressure sensor that detects the pressure in the fuel main pipe is provided immediately upstream
of the fuel pressure regulator.
The pressure and the temperature of the fuel are detected by these sensors and are input into the ECM.
These values are then converted by the ECM into the equivalent pressure at 215C to actuate the fuel gauge.
IGNITION SYSTEM
Because the spark plugs are susceptible to rust when used with natural gas, corrosion-resistant spark plugs
have been adopted. These spark plugs are the iridium-tipped spark plugs that have their metallic portion
plated.
