344 4-3. Do-it-yourself maintenance
CAUTION
The engine compartment contains many mechanisms and fluids that may
move suddenly, become hot, or become electrically energized. To avoid death
or serious injury observe the following precautions.
■When working on the engine compartment
●Keep hands, clothing, and tools away from the moving fan and engine
drive belt.
● Be careful not to touch the engine, radiator, exhaust manifold, etc. right
after driving as they may be hot. Oil and other fluids may also be hot.
● Do not leave anything that may burn easily, such as paper or rags, in the
engine compartment.
● Do not smoke, cause sparks or expose an open flame to fuel or the bat-
tery. Fuel and battery fumes are flammable.
● Be extremely cautious when working on the battery. It contains poisonous
and corrosive sulfuric acid.
● Take care because brake fluid can harm your hands or eyes and damage
painted surfaces.
If fluid gets on your hands or in your eyes, flush the affected area with
clean water immediately.
If you still experience discomfort, see a doctor.
■ When working near the electric c ooling fans or radiator grille
Be sure the engine switch is OFF. With the engine switch in the “ON” posi-
tion, the electric cooling fans may automatically start to run if the air condi-
tioning is on and/or the coolant temperature is high. ( P. 358)
■ Safety glasses
Wear safety glasses to prevent flying or falling material, fluid spray, etc. from
getting in the eyes.

■Effects of incorrect tire inflation pressure
Driving with incorrect tire inflation pressure ma y result in the following:
●Reduced fuel efficiency
●Reduced driving comfort and tire life
●Reduced safety
●Damage to the drive train
If a tire needs frequent re filling, have it checked by your Toyota dealer.
■Instructions for checking tire inflation pressure
When checking tire inflation pressure, observe the following:
●Check 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 mile or 1.5 km, you will get an accurate cold
tire inflation pressure reading.
●Always use a tire pressure gauge.
The appearance of the tire can be mi sleading. In addition, tire infla-
tion pressures that are even just a few pounds off can degrade ride
and handling.
●Do not bleed or reduce tire inflation pressure after driving. It is normal
for the tire inflation pressure to be higher after driving.
●Never exceed the vehicle capacity weight.
Passengers and luggage weight should be placed so that the vehicle
is balanced.

5-1. Essential information
Fuel pump shut off system
Follow the procedure below to restart the engine after the system is
activated.
Turn the engine switch to the “ACC” or “LOCK” position.
Restart the engine.
NOTICE
■Before starting the engine
Inspect the ground under the vehicle.
If you find that fuel has leaked on to the ground, the fuel system has been
damaged and is in need of repair. Do not restart the engine. Have the vehi-
cle checked and repaired by your Toyota dealer.
To minimize the risk of fuel leakage when the engine stalls or an air-
bag inflates upon collision, the fuel pump shut off system stops sup-
plying fuel to the engine.
