Odometer and trip meter
Odometer: Displays the total distance the vehicle has been driven.
Trip meter: Displays the distance the vehicle has been driven since the
meter was last reset. Trip meters A and B can be used to record and
display different distances independently.

Instrument panel light control
The brightness of the instrument panel lights can be adjusted.
Darker
Brighter
When the headlight switch is
turned on, the brightness will be
reduced slightly unless the con-
trol button is turned fully clock-
wise.
■Display
In the following situations, the correct outside temperature may not be dis-
played, or the display may take longer than normal to change.
●When stopped, or driving at low speeds (less than 12 mph [20 km/h])
●When the outside temperature has changed suddenly (at the entrance/
exit of a garage, tunnel, etc.)
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. 391)

When driving
●In order to maintain efficient engine braking and electrical charging
performance, do not use “D” (automatic transmission) or the 5th
gear (manual transmission).
●Due to the added load of the trailer, your vehicle's engine may
overheat on hot days (at temperatures 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. 391)
●Always place wheel blocks under both the vehicle and the trailer
wheels when parking. Apply the parking brake firmly, and put the
transmission in P (automatic transmission) or in 1 or R (manual
transmission). Avoid parking on a slope, but if unavoidable, do so
only after performing the following:
Apply the brakes and keep them applied.
Have someone place wheel blocks under both the vehicle and
trailer 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 1 or R (manual transmission) or P (automatic trans-
mission) and turn off the engine.
●When restarting after parking on a slope:
With the transmission in the P position (automatic transmis-
sion) or the clutch pedal (manual transmission) depressed,
start the engine. On vehicles with an automatic transmission,
be sure to keep the brake pedal pressed.
Shift into a forward gear. If reversing, shift into the R position.
Release the parking brake (also brake pedal on vehicles with
an automatic transmission), and slowly pull or back away from
the wheel blocks. Stop and apply the brakes.
Have someone retrieve the blocks.

Maintenance and care
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 cooling 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. 301)
■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 conditioning after use is normal.)
●Flat-looking tires or uneven tire wear
●Engine coolant temperature gauge 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 missing, 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, spongy feeling, pedal almost
touches the floor

5-2. Steps to take in an emergency
If your vehicle overheats
If your engine overheats:
Stop the vehicle in a safe place and turn off the air condi-
tioning system.
Check to see if steam is coming out from under the hood.
If you see steam:
Stop the engine. Carefully lift the hood after the steam
subsides and then restart the engine.
If you do not see steam:
Leave the engine running and carefully lift the hood.
Check to see if the cooling fans are operating.
If the fans are operating:
Wait until the temperature of the engine (shown on the
instrument cluster) begins to fall and then stop the
engine.
If the fans are not operating:
Stop the engine and call your Toyota dealer.
After the engine has cooled
down sufficiently, check the
engine coolant level and
inspect the radiator core (radi-
ator) for any leaks.STEP1

392 5-2. Steps to take in an emergency
■Overheating
If you observe the following, your vehicle may be overheating.
●The engine coolant temperature gauge enters the red zone or a loss of
power is experienced.
●Steam is coming from under the hood.
CAUTION
■To prevent an accident or injury when inspecting under the hood of
your vehicle
●If steam is seen coming from under the hood, do not open the hood until
the steam has subsided. The engine compartment may be very hot, caus-
ing serious injury such as burns.
●Keep hands and clothing away from the fan and other belts while the
engine is running.
●Do not loosen the coolant reservoir cap while the engine and radiator are
hot.
Serious injury, such as burns, may result from hot coolant and steam
released under pressure.
Add engine coolant if neces-
sary.
Water can be used in an emer-
gency if engine coolant is
unavailable.
(P. 403)
Have the vehicle checked at the nearest Toyota dealer as soon as
possible.
