■The meters and display illuminate when (Optitron type meter)
Vehicles without a smart key system:
The engine switch is in the “ON” position.
Vehicles with a smart key system:
The “ENGINE START STOP” switch is in IGNITION ON mode.
■ Eco Driving Indicator operates when
The vehicle is being driven with the shift lever in D.
■ When the average fuel consumption is reset
The average fuel consumption displayed on the accessory meter and “Past
Record” screen of the navigation system (if equipped) will be reset at the
same time.
■ The brightness of the instrument panel lights (Optitron type meter)
When the headlight switch is turned to on, the brightness will be reduced
slightly unless the control dial is turned fully upward.
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. 603)
■ While driving (Optitron type meter)
When the voltmeter indicates more than 19 V or less than 9 V, the battery
may be malfunctioning. Have your vehicle checked at your Toyota dealer.

●
Note that when making a turn, th e trailer wheels will be closer than
the vehicle wheels to the inside of the turn. Compensate by making
a larger than normal turning radius.
● Crosswinds and rough roads will adversely affect handling of your
vehicle and trailer, causing sway . Periodically check the rear to
prepare for being passed by large trucks or buses, which may
cause your vehicle and trailer to sway. If swaying occurs, firmly grip
the steering wheel, reduce speed immediately but gradually, and
steer straight ahead. Never increase speed. If you make no
extreme correction with the stee ring or brakes, your vehicle and
trailer will stabilize.
● Take care when passing other vehicles. Passing requires consider-
able distance. After passing a vehicle, do not forget the length of
your trailer, and be sure you hav e plenty of room before changing
lanes.
● In order to maintain engine braking efficiency when driving on a
long steep downgrade, do not use overdrive. Transmission shift
range position must be in 3 (standard type), or “4”, in the S mode
(multi-mode type).
● Due to the added load of the trailer, your vehicle’s engine may
overheat on hot days (at temperatur es over 85°F [30°C] when driv-
ing up a long or steep grade. If the engine coolant temperature
gauge indicates overheating, immedi ately turn off the air condition-
ing (if in use), pull your vehicle off the road and stop in a safe spot.

Engine coolant
The coolant level is sati sfactory if it is between the “F” and “L” lines on
the reservoir when the engine is cold.
Reservoir cap
“F” line
“L” line
If the level is on or below the “L”
line, add coolant up to the “F” line.
(P. 603)

■ Coolant selection
Only use “Toyota Super Long Life Coolant” or a similar high quality ethylene
glycol based non-silicate, non-amine, non-nitrite, and non-borate coolant
with long-life hybrid organic acid technology.
U.S.A.: “Toyota Super Long Life Coolant” is a mixture of 50% coolant and 50% deionized water. (Minimum temperature: -31 F [-35 C])
Canada: “Toyota Super Long Life Coolant” is a mixture of 55% coolant and 45% deionized water. (Minimum temperature: -44 F [-42 C])
For more details about engine coolant, contact your Toyota dealer.
■ If the coolant level drops within a short time of replenishing
Visually check the radiator, hoses, engine coolant reservoir caps, drain cock
and water pump.
If you cannot find a leak, have your Toyota dealer test the cap and check for
leaks in the cooling system.

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
● Voltmeter (if equipped) continua lly points higher or lower 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 roughly
● 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

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 sub-
sides and then restart the engine.
If you do not see steam:
Leave the engine running and carefully lift the hood.
Remove the engine compartment cover. (
P. 497)
Check to see if the cooling fan is operating.
If the fan is operating:
Wait until the temperature of the engine (shown on the
instrument panel) begins to fall and then stop the engine.
If the fan is not operating:
Stop the engine immediately 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.

■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 comes out 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 injuries such as burns.
● Keep hands and clothing away from the fan and drive belt while the engine
is running.
● Do not loosen the radiator cap, or 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. 616)
Have the vehicle inspected at the nearest Toyota dealer as soon as
possible.

Warning: The temperature grades of a tire assume that it is properly
inflated and not overloaded.
Excessive speed, underinflation, or
excessive loading, either sepa-
rately or in combination, can caus e heat buildup and possible tire fail-
ure.
