NOTICE
■
To prevent damage to the engine and its components
●Do not let the indicator needle of the tachometer enter the red zone, which
indicates the maximum engine speed.
● The engine may be overheating if the engine coolant temperature gauge is
in the red zone (H). In this case, immediately stop the vehicle in a safe
place, and check the engine after it has cooled completely. (
P. 437)

236 2-5. Driving information
●Instability happens more frequently when descending steep or long
downhill grades. Before descending, slow down and downshift. Do
not make sudden downshifts while descending steep or long down-
hill grades.
● Avoid holding the brake pedal down too long or applying the
brakes too frequently. This could cause the brakes to overheat and
result in reduced braking efficiency.
● Due to the added load of the trailer, your vehicle’s engine may
overheat on hot days (at temper atures over 85°F [30°C]) when
driving up a long or steep grade. If the engine coolant temperature
gauge indicates overheating, immediately turn off the air condition-
ing (if in use), pull your vehicle off the road and stop in a safe spot.
(  P. 437)
● Always place wheel blocks under both the vehicle’s and the
trailer’s wheels when parking. Ap ply the parking brake firmly, and
put the transmission in P (automatic transmission) or in 1 or R
(manual transmission). Avoid park ing on a slope, but if unavoid-
able, do so only after performing the following:
Apply the brakes and keep them applied.
Have someone place wheel blo cks under both the vehicle’s
and trailer’s wheels.
When the wheel blocks are in place, release the brakes slowly
until the blocks absorb the load.
Apply the parking brake firmly.
Shift into P (automatic transmission) or 1 or R (manual trans-
mission) and turn off the engine.
● When restarting after parking on a slope:
With the transmission in P (automatic transmission) or the
clutch pedal (manual transmission) depressed, start the
engine. On vehicles with an au tomatic transmission, be sure
to keep the brake pedal depressed.
Shift into a forward gear. If reversing, shift into R.

330 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 cooling fan or radiator grille
Be sure the engine switch is off.
With the engine switch on, the cooling fan may automatically start to run if
the air conditioning is on and/or the coolant temperature is high.
■ Safety glasses
Wear safety glasses to prevent flying or falling material, fluid spray, etc. from
getting in the eyes.

5-1. Essential information
If you think something is wrong
If you notice any of the following symptoms, your vehicle probably
needs adjustment or repair. Contact your Toyota dealer as soon as
possible.
■ Visible symptoms
●Fluid leaks under the vehicle
(Water dripping from the air cond itioning after use is normal.)
● Flat-looking tires or uneven tire wear
● Engine coolant temperature g auge needle continually points
higher than normal
■ Audible symptoms
●Changes in exhaust sound
● Excessive tire squeal when cornering
● Strange noises related to the suspension system
● Pinging or other noises related to the engine
■ Operational symptoms
●Engine misfire, stumbling or running rough
● Appreciable loss of power
● Vehicle pulls heavily to one side when braking
● Vehicle pulls heavily to one side when driving on a level road
● Loss of brake effectiveness, s pongy feeling, pedal almost
touches the floor

5-2. Steps to take in an emergency
If your vehicle overheats
In the following cases, the vehicle may be overheating.
●Engine coolant temperature gauge needle ( P. 155) reaches
the upper end, and engine output falls (There is no speed).
● Steam is coming out from the engine compartment.
Perform the following steps.
Stop the vehicle in a safe place, turn off the air conditioning
system, and stop the engine.
If steam is coming out:
When no more steam is coming out has been confirmed,
carefully open the hood.
If there is no steam coming out:
Carefully open the hood. After the engine has cooled
down sufficiently, inspect the
radiator core (radiator), hoses,
etc. for any leaks.
If there is a large quantity of
engine coolant leaking, imme-
diately contact your Toyota
dealer.
Inspect the amount of engine
coolant by checking if the res-
ervoir level is between “FULL”
and “LOW” lines.
