Engine oil consumption
● The amount of engine oil consumed depends on the oil viscosity, the
quality of the oil and the way the vehicle is driven.
● More oil is consumed under driving conditions such as high speeds, fre-
quent acceleration and deceleration.
● A new engine consumes more oil.
● 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.
● Oil consumption: Max. 1.1 qt./600 miles, 0.9 lmp. qt./600 miles (1.0 L per
1000 km). If the vehicle consumes more than this amount, contact your
Toyota dealer.
■ Resetting the engine oil maintenance data (U.S.A. only)

Turn the “POWER” switch to OFF mode with the trip meter A
shown.
Turn the “POWER” switch to ON mode with the trip meter reset but-
ton (P. 144) held down.

How to initialize the tire pressure warning system
Park the vehicle in safe place and turn the “POWER” switch to
OFF mode.
While the vehicle is moving, in itialization is not performed.
Adjust the tire inflation pressure to the specified cold tire infla-
tion pressure level. ( P. 470)
Make sure to adjust the tire pressure to the specified cold tire
inflation pressure level. The ti re pressure warning system will
operate based on this pressure level.
Turn the “POWER” switch to ON mode.
Push and hold the tire pressure
warning reset switch until the tire
pressure warning light blinks
slowly three times.
Wait for a few minutes with the ON mode, and then turn
“POWER” switch to OFF mode.

■If you push the tire pressure reset switch accidentally
If initialization is performed, adjust the tire in flation pressure to the speci-
fied level and initializ e the system again.
■When the initialization of the tire pressure warning system has
failed
Initialization can be comp leted in a few minutes. However, in the follow-
ing cases, the settings have not b een recorded and the system will not
operate properly. If repeated attempts to record tire inflation pressure
settings are unsuccessful, have the vehicle inspected by your Toyota
dealer.
●When operating the tire pressure warning reset switch, the warning
light does not flash (The tires cann ot be initializes whiled the vehicle
is moving.).
●After driving for a certain period of time since the initialization has
been completed, the warning light flashes.
■Routine tire inflation pressure checks
The tire pressure warning system doe s not replace routine tire inflation
pressure checks. Make sure to check tire inflation pressure as part of
your routine of daily vehicle checks.

CAUTION
■When inspecting or replacing tires
Observe the following precautions to prevent accidents. Failure to do so
may cause damage to parts of the drive train, as well as dangerous han-
dling characteristics, which may le ad to fatal or injury accidents.
●Do not mix tires of different makes, models, tread patterns or tread-
wear.
●Do not use tire sizes other than those recommended by Toyota.
●Do not mix radial, bias-belted, or bias-ply tires.
●Do not mix summer, all season and winter tires.
●Do not use tires that have been used on another vehicle.
●Do not use tires if you do not know how they were used previously.
■When initializing the tire pressure warning system
Do not push the reset switch without fi rst adjusting the tire inflation pres-
sure to the specified level. Otherwise, the tire pressure warning light may
not come on even if the tire inflation pressure is low, or it may come on
when the tire inflation pressure is actually normal.
NOTICE
■Repairing or replacing tires, wheels and tire pressure warning
valves and transmitters
●When removing or fitting the wheels, tires or the tire pressure warning
valve and transmitter, contact your Toyota dealer as the tire pressure
warning valve and transmitter may be damaged if not handled cor-
rectly.
●When replacing tires, make sure also to replace the tire pressure
warning valve and transmitter grommets.
■Do not use puncture sealant sprays to repair flats
Puncture sealant sprays may damage tire pressure tire pressure warn-
ing valves and transmitters.
