■How to read oil container labels
Some oil containers are labeled wi th ILSAC certification marks that
help you to select the proper oil.
■Engine oil consumption
●The amount of engine oil consumed depe nds 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 and fre-
quent acceleration and deceleration.
●A new engine consumes more oil.
●When judging the amount of oil consumpt ion, keep in mind that the oil may
have become diluted, making it difficult to judge the true level accurately.
●Oil consumption: Max. 1.1 qt./600 miles, 0.9 lmp.qt./600 miles (1.0 L per 1000
km)
●If your vehicle consumes more than 1.1 qt. (1.0 L, 0.9 lmp.qt.) every 600 miles
(1000 km), contact your Lexus dealer.
■After changing the engine oil (U.S.A. only)
The oil change system should be reset. Perform the following procedures:
Switch the display to the odometer ( P. 128) when the engine is running.
Turn the “ENGINE START STOP” switch OFF.
While pressing the trip meter reset button, set the “ENGINE START
STOP” switch to the IGNITION ON mode (but do not start the engine
because otherwise the reset mode will be cancelled). Continue to press
and hold the button until the trip meter displays “000000”.

When recharging, the battery produces hydrogen gas which is flammable and
explosive. Therefore, before recharging:
●If recharging with the 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 discon-
necting the charger cables to the battery.
■After recharging/reconnecting the battery
In some cases, the engine may not start. Follow the procedure bellow to initialize
the system.
Shift the shift lever to “P”, and turn the “ENGINE START STOP” switch
OFF.
Open and close any of the doors.
Start the engine. (If the engine does not start first time, repeat the proce-
dure.)
If the engine will not start even after mult iple attempts at the above method, contact
your Lexus dealer.
CAUTION
■Chemicals in the battery
A battery contains poisonous and corrosive sulfuric acid and may produce hydro-
gen gas which is flammable and explosive. To reduce the risk of death or serious
injury, take the following precautions while working on or near battery:
●Do not cause sparks by touching the battery terminals with tools.
●Do not smoke or light a match near the battery.
●Avoid contact with eyes, skin and clothes.

Maintenance and care
Initializing the tire pressure warning system■ The tire pressure warning system must be initialized when the tire
inflation pressure is changed (such as when changing traveling
speed.)
When the tire pressure warning sy stem is initialized, the current tire
inflation pressure is set as the benchmark pressure.
■ How to initialize the tire pressure warning system
To initialize the system, use the satellite switch. ( P. 2 3 6 )
Park the vehicle in safe plac e and turn the “ENGINE START
STOP” switch to OFF.
While the vehicle is moving, initialization is not performed.
Adjust the tire inflation pressure to the specified cold tire inflation
pressure level. ( P. 4 0 7 )
Make sure to adjust the tire pressure to the specified cold tire inflation
pressure level. The tire pressure warning system will operate based on
this pressure level.
Turn the “ENGINE START STOP” switch to IGNITION ON
mode.
