Engine oil consumption
lThe amount of engine oil consumed depends on the oil viscosity, the
quality of the oil and the way the vehicle is driven.
l More oil is consumed under driving conditions such as high speeds and
frequent acceleration and deceleration.
l A new engine consumes more oil.
l When judging the amount of oil consumption, keep in mind that the oil
may have become diluted, making it difficult to judge the true level accu-
rately.
l Oil consumption: Max. 1.1 qt./600 miles, 0.9 lmp.qt./600 miles (1.0 L per
1000 km)
l If you consume more than 1.1 qt. (1.0 L, 0.9 lmp.qt.) every 600 miles
(1000 km), contact your Toyota dealer.
n After changing the engine oil (except Canada)
The oil change system should be reset. Perform the following procedures:
Turn the engine switch off with the Trip A reading shown.( →P. 140)
Turn the engine switch to the ON position while holding down the
trip meter reset button.
Continue to press and hold the button until the trip meter displays
000000.
If the system fails to reset, the light will continue flashing.

Maintenance and care
Engine coolant
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
LOW
If the level is on or below the
LOW line, add coolant up to the
FULL line.
nIf the coolant level drops within a short time after replenishing
Visually check the radiator, hoses, reservoir cap, radiator cap, drain cock
and water pump.
If you cannot find a leak, have your Toyota dealer pressure test the cap and
check for leaks in the cooling system.
n Coolant selection
Only use “Toyota Super Long Life Coolant” or similar high quality ethylene
glycol based non-silicate, non-amine, non-nitrite and non-borate coolant with
long-life hybrid organic acid technology.
Except Canada:“Toyota Super Long Life Coolant” is a mixture of 50% cool- ant and 50% deionized water. (Enabled: -31 °F [-35°C])
Canada: “Toyota Super Long Life Coolant” is a mixture of 55% coolant and 45% deionized water. (Enabled: -44 °F [-42 °C])
For more details about engine coolant, contact your Toyota dealer.
