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)
Perform the following steps:
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.
Keep pressing the button for longer than 5 seconds after the
“POWER” switch is in ON mode.
When the trip meter A indicates “000000” and the light goes off, the system

■Before recharging
When recharging, the 12 volt battery produces hydrogen gas which is flam-
mable and explosive. Therefore, before recharging:
● If recharging with the 12 volt battery installed on the vehicle, be sure to
disconnect the ground cable.
● Make sure the power switch on the charger is off when connecting and
disconnecting the charger cables to the 12 volt battery.
■ After recharging/reconnecting the 12 volt battery
In some cases, the hybrid system may not start. Follow one or both of the
following procedures:
● After opening and closing the driver’s door, wait 10 seconds then attempt
to start the engine. (If the system does not start first time, repeat the pro-
cedure.)
● With the shift lever in “P” and the “POWER” switch in the OFF mode,
open and close any door, then attempt to start the hybrid system.
If the system will not start even after multiple attempts at both methods, con-
tact your Toyota dealer.

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 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

valve and transmitter, contact your Toyota dealer as the tire pressure
warning valve and transmitter may be damaged if not handled cor-

■If the tire pressure warning light comes on after blinking for 1
minute frequently
If the tire pressure warning light comes on after blinking for 1 minute fre-
quently when the “POWER” switch
is turned to ON mode, have it
checked by your Toyota dealer.
NOTICE
■Precaution when installing a different tire
When a tire of a different specification or maker is installed, the tire pres-

CAUTION
■When the power steering warning light comes on
The steering wheel may become extremely heavy.
If the steering wheel becomes heavier than usual when operating, firmly
hold and operate it using more force than usual.
■
If the tire pressure warning light comes on
Be sure to observe the following precautions. Failure to do so could
cause loss of vehicle control and result in death or serious injury. • Stop your vehicle in a safe place as soon as possible. Adjust thetire inflation pressure immediately.
• If the tire pressure warning light comes on even after tire inflation pressure adjustment, it is probable that you have a flat tire. Check
the tires. If the tire is flat, change to the spare tire and have the flat
tire repaired by the nearest Toyota dealer.
• Avoid abrupt maneuvering and brak ing. If the vehicle tires deterio-
rate, you could lose control of th e steering wheel or the brakes.

Starting the hybrid system when the battery is discharged
The hybrid system cannot be started by push-starting.
■ Avoiding a discharged 12 volt battery
● Turn off the headlights and the audio system while the hybrid system is
turned off.
● Turn off any unnecessary electrical components when the vehicle is run-
ning at a low speed for an extended period, such as in heavy traffic, etc.
Start the engine of the second vehicle. Increase the engine
speed slightly and maintain at that level for approximately
five minutes to recharge the 12 volt battery of your vehicle.
Open and close any of the doors with the “POWER” switch
OFF.
Maintain the engine speed on the second vehicle and turn
the “POWER” switch to the ON mode, then start the vehi-
cle’s engine.
Make sure the “READY” light comes on. If the “READY”
light will not come on and the hybrid system will not start
after you recharge the battery, do the following procedure.
Turn the hybrid system off. Open and close the driver’s
door. Then push the “POWER” switch briefly and firmly. If
the light does not come on, contact your Toyota dealer.
Once the vehicle’s engine has started, remove the jumper
cables in the exact reverse order in which they were con-
nected.

dealer as soon as possible.STEP4
