With the engine at operating
temperature and turned off,
check the oil level on the dip-
stick.
■Checking the engine oil
1 Park the vehicle on level
ground. After warming up the
engine and turning it off, wait
more than 5 minutes for the
oil to drain back into the bot-
tom of the engine.Checking and adding the

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. ( P.519)
■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 tem-
perature: -31°F [-35°C])
Canada:
“Toyota Super Long Life Coolant” is
a mixture of 55% coolant and 45%
deionized water. (Minimum tem-
perature: -44°F [-42°C])
For more details about coolant, con-
tact 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 sys-
tem.
Check the radiator and con-
denser and clear away any for-
eign objects. If either of the
above parts is extremely dirty or
you are not sure of their condi-
tion, have your vehicle
inspected by your Toyota dealer.
Checking the engine cool-
ant
WARNING
■When the engine is hot
Do not remove the engine coolant
reservoir cap.
The cooling system may be under
pressure and may spray hot cool-
ant if the cap is removed, causing
serious injuries, such as burns.
NOTICE
■When adding coolant
Coolant is neither plain water nor
straight 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.

Maintenance and care
■Checking fluid level
The brake fluid level should be
between the “MAX” and “MIN”
lines on the tank.
■Adding fluid
1 Slide and lift up the rubber
strip to partly remove it as
shown. 2
Disconnect the claws and
remove the service cover.
3 Remove the reservoir cap.
4 Add brake fluid slowly while
checking the fluid level.
Make sure to check the fluid
type and prepare the necessary
item.
 Fluid type
FMVSS No.116 DOT 3 or SAE
J1703 brake fluid
FMVSS No.116 DOT 4 or SAE
J1704 brake fluid
Item
Clean funnel
■Brake fluid can absorb moisture
from the air
Excess moisture in the brake fluid
can cause a dangerous loss of brak-
ing efficiency. Use only newly
opened brake fluid.
WARNING
■When the engine is hot
Do not touch the radiator or con-
denser as they may be hot and
cause serious injuries, such as
burns.

When trouble arises
1 Stop the engine. Set the
parking brake and shift the
shift lever to P (continuously
variable transmission) or N
(manual transmission).
2 Remove the mud, snow or
sand from around the front
wheels.
3 Place wood, stones or some
other material under the front
wheels to help provide trac-
tion.
4 Restart the engine.
5 Shift the shift lever to D or R
(continuously variable trans-
mission) or 1 or R (manual
transmission) and release
the parking brake. Then,
while exercising caution,
depress the accelerator
pedal.
■When it is diffic ult to free the
vehicle
Press the switch to turn off
TRAC.
WARNING
●If steam is seen coming from
under the hood, do not open the
hood until the steam has sub-
sided. The engine compart-
ment may be very hot.
●Keep hands and clothing (espe-
cially a tie, a scarf or a muffler)
away from the fan and belts.
Failure to do so may cause the
hands or clothing to be caught,
resulting in serious injury.
●Do not loosen the coolant reser-
voir 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 suffi-
ciently. 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 precau-
tions:
●Avoid contaminating the coolant
with foreign matter (such as
sand or dust etc.).
●Do not use any coolant additive.
If the vehicle becomes
stuck
Carry out the following pro-
cedures if the tires spin or
the vehicle becomes stuck
in mud, dirt or snow:
