With the engine at operating
temperature and turned off,
check the oil level on the dip-
stick.
■Checking the engine oil

ground. After warming up the
engine and turning it off, wait
more than 5 minutes for the
oil to drain back into the bot-

The coolant level is satisfactory
if it is between the “FULL” and
“LOW” lines (type A) or “MAX”
and “MIN” lines (type B) on the
reservoir when the engine is
cold.
Ty p e A
Reservoir cap
“FULL” line
“LOW” line
I f t he le ve l is on o r be low th e “L O W ”
line, add coolant up to the “FULL”
line. ( P.550)
Ty p e B
Reservoir cap
“MAX” line
“MIN” line
If the level is on or below the “MIN”
line, add coolant up to the “MAX”
line. ( P.550)
■Coolant selection
Only use “Toyota Super Long Life
Coolant” or a similar high quality
ethylene glycol ba sed 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% c oolant and 50%
deionized water. (Minimum tem-
perature: -31°F [-35°C])
Canada:
“Toyota Super Long Life Coolant” is
a mixture of 55% c oolant 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.

■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.
