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. 566)
■ Vo l t m e t e r
When the voltmeter indicates 19 V or higher or 9 V or lower whi le the engine
is running, there may be a battery or charging system malfunction. Have the
vehicle inspected at your Toyota dealer.
■ Engine oil pressure gauge
When the value of the engine oil pressure gauge drops while the engine is
running, stop the vehicle in a safe place immediately and check the amount
of engine oil. ( P. 471)
When the oil pressure drops even though the engine oil amount h as not
decreased, or if the oil pressure does not increase when engine oil is
added, contact your Toyota dealer, as there may be a problem wi th the lubri-
cation system.

4-1. Before driving
●Avoid jerky starts or sudden acceleration.
● Avoid jerky steering and sharp turns, and slow down before maki ng
a turn.
● Note that when making a turn, the trailer wheels will be closer than
the vehicle wheels to the inside of the turn. Compensate by mak ing
a wider than normal turning radius.
● Slow down before making a turn, in crosswinds, on wet or slippe ry
surfaces, etc.
Increasing vehicle speed can destabilize the trailer.
● Take care when passing other vehicles. Passing requires consider-
able distance. After passing a vehicle, do not forget the lengt h of
your trailer, and be sure you have plenty of room before changi ng
lanes.
● To maintain engine braking efficiency and charging system perfo r-
mance when using engine braking, do not put the transmission in
D.
If in the S mode, the transmissi on shift range position must be in 6
or lower. ( P. 218)
● Instability happens more frequently when descending steep or lo ng
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 bra kes
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 drivin g
up a long or steep grade. If the engine coolant temperature gau ge
indicates overheating, immediately turn off the air conditionin g (if in
use), pull your vehicle off the road and stop in a safe spot.

Driving
●If the engine coolant temperature is too low, the four-wheel dr ive control
system may not be able to shift. When the engine is warmer pres s the
switch again.
If the low speed four-wheel drive indicator light or the center differential lock
indicator light continues to blink even after attempting the ab ove, there may
be a malfunction in the engine, the brake system or the four-wh eel drive sys-
tem. In this case, you may not be able to shift between H4 and L4, and the
center differential lock may not be operable. Have the vehicle inspected by
your Toyota dealer immediately.
WARNING
■ While driving
Never move the four-wheel drive control switch if the wheels ha ve lost trac-
tion. Doing so may cause an accident resulting in death or serious injury.
■ When the vehicle is parked
If the shift lever is moved before the low speed four-wheel dri ve indicator
turns on/off, the transfer mode may not be shifted completely. The transfer
mode disengages both the front and rear driveshafts from the po wertrain
and allows the vehicle to move regardless of the shift position . (At this time,
the indicator blinks and the buzzer sounds.)
Therefore, the vehicle is free to roll even if the automatic tr ansmission is in
P. You or someone else could be seriously injured. You must com plete the
shifting of the transfer mode.
NOTICE
■ To prevent damage to the center differential
● For normal driving on dry and hard surface roads, unlock the ce nter differ-
ential.
● Unlock the center differential after the wheels are out of the ditch or off the
slippery or bumpy surface.
● Do not push the center differential lock/unlock switch when the vehicle is
turning or when its wheels are spinning freely off the ground.

Maintenance and care
Washer fluid
( P. 4 8 1 )• Water or washer fluid containing antifreeze (for win-
ter use)
• Funnel (used only for adding water or washer fluid)
WARNING
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 eng ine
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 ra gs, in the
engine compartment.
● Do not smoke, cause sparks or expose an open flame to fuel or t he bat-
tery. Fuel and battery fumes are flammable.
● Be extremely cautious when working on the battery. It contains poisonous
and corrosive sulfuric acid.
■ When working near the electric cooling fans or radiator grille
Be sure the engine switch is off. With the engine switch in IGN ITION 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. 475)
■ When working on or under the vehicle
Do not get under the vehicle with just the jack supporting it.
Always use automotive jack stands or other solid supports.
■ 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.

6-3. Do-it-yourself maintenance
The coolant level is satisfactory if it is between the “F” and “L” lines on
the reservoir when the engine is cold.
Reservoir cap
“F”
“L”
If the level is on or below the “L”
line, add coolant up to the “F” 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-bora te coolant with
long-life hybrid organic acid technology.
“Toyota Super Long Life Coolant” is a mixture of 50 % coolant and 50 %
deionized water. (Minimum temperature: -31 F [-35 C])
For more details about engine coolant, contact your Toyota deal er.
■ If the coolant level drops within a short time of replenishing
Visually check the radiator, hoses, engine coolant reservoir cap, radiator 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.
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 straight antifreeze. The cor rect 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 damage to parts or paint.

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 (radiat or) 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 needle of the engine c oolant temperature gauge (P. 97)
enters the red zone or a loss of engine power is experienced. ( For
example, the vehicle s peed does not increase.)
● Steam is coming from under the hood.
