WARNING
■The information display at low temperatures
Allow the interior of the vehicle to warm up before using the liquid crystal
information display. At extremely low temperatures, the information display
monitor may respond slowly, and display changes may be delayed.
For example, there is a lag between the driver’s shifting and the new gear
number appearing on the display. This lag could cause the driver to down-
shift again, causing rapid and excessive engine braking and possibly an
accident resulting in personal death or injury.
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. 563)

1824-1. Before driving
●Slow down before making a turn, in crosswinds, on wet or slippery
surfaces, etc.
Increasing vehicle speed c an destabilize the trailer.
● Take care when passing other vehicles. Passing requires consider-
able distance. After passing a vehi cle, do not forget the length of
your trailer, and be sure you hav e plenty of room before changing
lanes.
● Vehicles with an automatic transm ission: To maintain engine brak-
ing efficiency and charging syst em performance when using engine
braking, do not use the transmiss ion in D. If in the S mode, the
transmission shift range position must be in 5 or lower.
● Vehicles with a manual transmission: To maintain engine braking
efficiency and charging system performance when using engine
braking, do not use t he fifth gear (5-speed manual transmission) or
the sixth gear (6-speed manual transmission).
● 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 over-
heat on hot days (at temperatures over 85°F [30°C]) when driving
up a long or steep grade. If t he engine coolant temperature gauge
indicates overheating, immediately turn off the air conditioning (if in
use), pull your vehicle off the road and stop in a safe spot.

Maintenance and care
■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% deion-
ized water. (Minimum temperature: -31 °F [-35 °C])
Canada:
“Toyota Super Long Life Coolant” is a mixture of 55% coolant and 45% deion-
ized water. (Minimum temperature: -44 °F [-42 °C])
For more details about coolant, contact your Toyota dealer.
■ If the coolant level drops within a short time of replenishing
Visually check the radiator, hoses, engine coolant reservoir cap, 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.
WARNING
■When the engine is hot
Do not remove the radiator cap and engine coolant reservoir cap. ( →P. 563)
The cooling system may be under pressure and may spray hot coolant if the
cap is removed, causing serious injuries, such as burns.
NOTICE
■ When adding coolant
Coolant is neither plain water nor stra ight antifreeze. The correct mixture of
water and antifreeze must be used to provide proper lubrication, corrosion
protection and cooling. Be sure to read the antifreeze or coolant label.
■ If you spill coolant
Be sure to wash it off with water to prevent it from damaging parts or paint.

5128-2. Steps to take in an emergency
If you think something is wrong
●Fluid leaks under the vehicle.
(Water dripping from the air co nditioning after use is normal.)
● Flat-looking tires or uneven tire wear
● Engine coolant temperature gauge needle continually points higher
than normal.
● Changes in exhaust sound
● Excessive tire squeal when cornering
● Strange noises related to the suspension system
● Pinging or other noises related to the engine
● Engine misses, 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, spon gy feeling, pedal almost touches
the floor
If you notice any of the follow ing symptoms, your vehicle proba-
bly needs adjustment or repair. Contact your Toyota dealer as
soon as possible.

(If equipped)
Indicates that the automatic transmission fluid
temperature is too high.A buzzer also sounds.
→ Immediately stop the vehicle in a safe
place, shift the shift lever to P and wait until
the message and light go off.
If the message and ligh t go off, you may
start the vehicle again.
If the message and light do not go off, con-
tact your Toyota dealer.
Indicates that the engine coolant temperature is
too high. A buzzer also sounds.
→ P. 563
Indicates abnormal engine oil pressure
The warning light may come on if the engine oil
pressure is too low.
A buzzer also sounds.
→ Immediately stop the vehicle in a safe place
and contact your Toyota dealer.
Indicates a malfunction in the vehicle’s charging
system.
→ Immediately stop the vehicle in a safe place
and contact your Toyota dealer. Continuing
to drive the vehicle may be dangerous.

When trouble arises
8-2. Steps to take in an emergency
If your vehicle overheats
●The needle of the engine coolant temperature gauge ( →P. 8 8 )
enters the red zone or a loss of engine power is experienced. (For
example, the vehicle sp eed does not increase.)
● “High Engine Coolant Temperature” is shown on the multi-informa-
tion display. (if equipped)
● Steam comes out from under the hood.
Stop the vehicle in a safe place and turn off the air conditioning sys-
tem, and then stop the engine.
If you see steam:
Carefully lift the hood after the steam subsides.
If you do not see steam:
Carefully lift the hood.
After the engine has cooled
down sufficient ly, inspect the
hoses and radiator core (radia-
tor) for any leaks.
Radiator
Cooling fan
If a large amount of coolant leaks,
immediately contact your Toyota
dealer.
The coolant level is satisfactory
if it is between the “FULL” and
“LOW” lines on the reservoir.Reservoir

5648-2. Steps to take in an emergency
Add coolant if necessary.
Water can be used in an emer-
gency if coolant is unavailable.
Start the engine to check that the radiator cooling fan operates and
to check for coolant leaks from the radiator or hoses.
If the fan is not operating:
Stop the engine immediately and contact your Toyota dealer.
If the fan is operating:
Have the vehicle in spected at the nearest Toyota dealer.

WARNING
■When inspecting under the hood of your vehicle
Observe the following precautions.
Failure to do so may result in serious injury such as burns.
● 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.
● Keep hands and clothing away from the fans, etc., while the engine is run-
ning.
● Do not loosen the radiator cap and the coolant reservoir cap while the
engine and radiator are hot.
High temperature steam or coolant could spray out.
NOTICE
■When adding engine coolant
Add coolant slowly after the engine has cooled down sufficiently. Adding
cool coolant to a hot engine too quickly can cause damage to the engine.
■ To prevent damage to the cooling system
Observe the following precautions:
● Avoid contaminating the coolant with foreign matter (such as sand or dust,
etc.).
● Do not use any coolant additives.
