nEngine 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.
lMore oil is consumed under driving conditions such as high speeds and fre-
quent acceleration and deceleration.
lA new engine consumes more oil.
lWhen judging the amount of oil consumption, keep in mind that the oil may
have become diluted, making it difficult to judge the true level accurately.
lOil consumption: Max. 1.1 qt./600 miles (0.9 Imp. qt./600 miles, 1.0 L/1000
km)
lIf your vehicle consumes more than 1.1 qt. (1.0 L, 0.9 Imp. qt.) every 600 miles
(1000 km), contact your Lexus dealer.
nAfter changing the engine oil (U. S. A. only)
The engine oil maintenance data should be reset. Perform the following procedure:
Display the trip meter “A” (→P. 167), then turn the “ENGINE START
STOP” switch off.
While pressing the “ODO/TRIP” button, turn the “ENGINE START
STOP” switch to ON mode.

nHow to initialize the tire pressure warning system
Park the vehicle in safe place and turn the “ENGINE START
STOP” switch off.
While the vehicle is moving, initialization is not performed.
Adjust the tire inflation pressure to the specified cold tire inflation
pressure level. (→P. 6 0 2 )
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.
Press and hold the tire pressure
warning reset switch until the tire
pressure warning light flashes
slowly 3 times.
Wait for a few minutes in “ENGINE START STOP” switch to on,

Maintenance and care
nInitializing the tire pressure warning system
Initialize the tire pressure warning system with the tire inflation pressure adjusted to
the specified level.
nIf you push the tire pressure warning reset switch accidentally
If initialization is performed, adjust the tire inflation pressure to the specified level
and initialize the tire pressure warning system again.
nWhen the initialization of the tire pressure warning system has failed
Initialization can be completed in a few minutes. However, in the following cases,
the settings have not been 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 Lexus dealer.
lWhen operating the tire pressure warning reset switch, the tire pressure warn-
ing light does not flash 3 times.
lAfter carrying out the initialization procedure, the tire pressure warning light
flashes for 1 minute then stays on after driving for 20 minutes.
nRoutine tire inflation pressure checks
The tire pressure warning system does not replace routine tire inflation pressure
checks. Make sure to check tire inflation pressure as part of your routine of daily
vehicle checks.

Maintenance and care
CAUTION
nTire pressure warning system operation
The tire pressure warning system may not provide warning immediately if a tire
bursts or if sudden air leakage occurs.
nWhen 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 handling characteristics,
which may lead to an accident resulting in death or serious injury.
lDo not mix tires of different makes, models or tread patterns. Also, do not mix
tires of remarkably different treadwear.
lDo not use tire sizes other than those recommended by Lexus.
lDo not mix differently constructed tires (radial, bias-belted or bias-ply tires).
lDo not mix summer, all season and snow tires.
lDo not use tires that have been used on another vehicle.
Do not use tires if you do not know how they were used previously.
nWhen initializing the tire pressure warning system
Do not push the tire pressure warning reset switch without first adjusting the tire
inflation pressure 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.

5-2. Steps to take in an emergency
nWhen the tire pressure warning light comes on
Check the tire inflation pressure and adjust to the appropriate level. Pushing the tire
pressure warning reset switch will not turn off the tire pressure warning light.
nThe tire pressure warning light may come on due to natural causes
The tire pressure warning light may come on due to natural causes such as natural
air leaks and tire inflation pressure changes caused by temperature. In this case,
adjusting the tire inflation pressure will turn off the warning light (after a few min-
utes).
nWhen a tire is replaced with a spare tire
Vehicles with a compact spare tire
The compact spare tire is not equipped with a tire pressure warning valve and trans-
mitter. If a tire goes flat, the tire pressure warning light will not turn off even though
the flat tire has been replaced with the spare tire. Replace the spare tire with the
repaired tire and adjust the tire inflation pressure. The tire pressure warning light
will go off after a few minutes.
Vehicles with a full-size spare tire
The spare tire is also equipped with the tire pressure warning valve and transmitter.
The tire pressure warning light will turn on if the tire inflation pressure of the spare
tire is low. If a tire goes flat, even though the flat tire is replaced with the spare tire,
the tire pressure warning light does not turn off. Replace the spare tire with the
repaired tire and adjust the proper tire inflation pressure. The tire pressure warning
light will turn off after a few minutes.
