*1: These lights turn on when the engine switch is turned to the “ON” position(vehicles without a smart key system) or IGNITION ON mode (vehicles with
a smart key system), to indicate that a system check is being performed.
They will turn off after the engine is started, or after a few seconds. There
may be a malfunction in a system if the lights do not come on, or turn off.
Have the vehicle inspected by your Toyota dealer.
*2: The light flashes to indicate that the system is operating.
*3: In order to confirm operation, the BS M outside rear view mirror indicators
illuminate in the following situations:
• When the engine switch is turned to the “ON” position (vehicles without a smart key system) or IGNITION ON mode (vehicles with a smart key sys-
tem) while the BSM main switch is set to ON.
• When the BSM main switch is set to ON while the engine switch is in the “ON” position (vehicles without a smart key system) or IGNITION ON
mode (vehicles with a smart key system).
If the system is functioning correctly, the BSM outside rear view mirror indi-
cators will turn off after a few seconds.
If the BSM outside rear view mirror indicators do not illuminate or do not
turn off, there may be a malfunction with the system. If this occurs, have the
vehicle inspected by your Toyota dealer.
CAUTION
■ If a safety system warning light does not come on
Should a safety system light such as the ABS and SRS warning light not
come on when you start the engine, this could mean that these systems are
not available to help protect you in an accident, which could result in death
or serious injury. Have the vehicle inspected by your Toyota dealer immedi-
ately if this occurs.
NOTICE
■ To prevent damage to the engine and its components
The engine may be overheating if the high engine coolant temperature
warning light flashes or turns on. In this case, immediately stop the vehicle
in a safe place, and check the engine after it has cooled completely.

4-1. Before driving
●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.
(  P. 653)
● Always place wheel blocks under both the vehicle’s and the trailer’s
wheels when parking. Apply the pa rking brake firmly, and put the
transmission in P. 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’s and
trailer’s wheels.
When the wheel blocks are in pl ace, release the brakes slowly
until the blocks absorb the load.
Apply the parking brake firmly.
Shift into P and turn off the engine.
● When restarting after parking on a slope:
With the transmission in P, start the engine. Be sure to keep the
brake pedal pressed.
Shift into a forward gear. If reversing, shift into R.
Release the parking brake and brake pedal, and slowly pull or
back away from the wheel blocks. Stop and apply the brakes.
Have someone retrieve the blocks.

6-3. Do-it-yourself maintenance
CAUTION
■When working near the electric cooling fans or radiator grille
Vehicles without a smart key system
Be sure the engine switch is off. With the engine switch in the “ON” position,
the electric cooling fans may automatically start to run if the air conditioning
is on and/or the coolant temperature is high. ( P. 544)
Vehicles with a smart key system
Be sure the engine switch is off. With the engine switch in IGNITION ON
mode, the electric cooling fans may automatically start to run if the air condi-
tioning is on and/or the coolant temperature is high. ( P. 544)
■ Safety glasses
Wear safety glasses to prevent flying or falling material, fluid spray, etc.
from getting in your eyes.
NOTICE
■If you remove the air cleaner filter
Driving with the air cleaner filter removed may cause excessive engine wear
due to dirt in the air.

The coolant level is satisfactory if it is between the “FULL” and “LOW”
lines on the reservoir when the engine is cold.Reservoir cap
“FULL” line
“LOW” line
If the level is on or below the
“LOW” line, add coolant up to the
“FULL” line.
■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 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.

When trouble arises
7-2. Steps to take in an emergency
If your vehicle overheats
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 sufficiently, inspect the hoses and
radiator core (radiator) for any leaks.
Radiator
Cooling fans
If a large amount of coolant
leaks, immediately contact your
Toyota dealer.
The following may indicate that your vehicle is overheating.
● The high engine coolant temperature warning light ( P. 615) comes
on or a loss of engine power is experienced. (For example, the

The coolant level is satisfactory if it is between the “FULL” and
“LOW” lines on the reservoir.
Reservoir
“FULL”
“LOW”
Add coolant if necessary.
Water can be used in an emer-
gency if coolant is unavailable.
Start the engine and turn the air conditioning system on to check
that the radiator cooling fans oper ate and to check for coolant leaks
from the radiator or hoses.
The fans operate when the air conditioning system is turned on immedi-
ately after a cold start. Confirm that the fans are operating by checking the
fan sound and air flow. If it is difficult to check these, turn the air condition-
ing system on and off repeatedly. (The fans may not operate in freezing
temperatures.)
If the fans are not operating:
Stop the engine immediately and contact your Toyota dealer.
If the fans are operating:
Have the vehicle in spected at the nearest Toyota dealer.

When trouble arises
CAUTION
■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 (especially a tie, a scarf or a muffler) away from
the fans and belts. Failure to do so may cause the hands or clothing to be
caught, resulting in serious injury.
● Do not loosen 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 additive.
