■Recommended viscosity
SAE 5W-30 is the best choice for
good fuel economy and good
starting in cold weather.
If SAE 5W-30 is not available, SAE
10W-30 may be used. However, it
should be replaced with SAE 5W-
30 at the next oil change.
■How to read oil container labels
Some oil containers are labeled wi th ILSAC certification marks that
help you to select the proper oil.

Maintenance and care
■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 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 you consume more than 1.1 qt. (1.0 L, 0.9 lmp.qt.) every 600 miles (1000 km),
contact your Lexus dealer.
■Changing the engine oil (U.S.A. only)
To reset the oil change system, follow the procedure below:
1. Turn the engine switch OFF.
2. While pressing the trip meter reset knob ( P. 100), set the engine switch to the
IG-ON mode. Continue to press and hold the knob until the trip meter displays
000000.
CAUTION
■Used engine oil
●Used engine oil contains potentially harmful contaminants which may cause skin
disorders such as inflammati on or skin cancer, so care should be taken to avoid
prolonged and repeated contact. To remove used engine oil from your skin, wash
thoroughly with soap and water.
●Dispose of used oil and filters only in a safe and acceptable manner. Do not dis-
pose of used oil and filters in househol d trash, in sewers or onto the ground.
Call your Lexus dealer, service station or auto parts store for information con-
cerning recycling or disposal.
●Do not leave used engine oil within the reach of children.

(Flashing and then con-tinuously on)
(If equipped)
(Flashing)Indicates that the radar
cruise control system is
unable to judge vehicle-
to-vehicle distance.
• Switch the driving mode to either the normal or
PWR mode.
• If the windshield wipers are on, turn them off or
set them to either the
intermittent or the slow
mode.
(Flashing)
(If equipped)
Indicates that your vehi-
cle is nearing the vehicle
ahead (in radar cruise
mode).
Slow the vehicle by apply-
ing the brakes.
■Changing the engine oil (U.S.A. only)
Make sure to reset the oil change system. ( P. 2 6 4 )
■Warning light display in radar cruise mode
In the following cases, the warning light may not be displayed even if vehicle-to-
vehicle distance closes.
●When your vehicle and the vehicle ahead are traveling at the same speed or the
vehicle ahead is traveling more quickly than your vehicle
●When the vehicle ahead is traveling at a very low speed
●Immediately after cruise control speed is set
●At the instant the accelerator pedal is depressed

Lubrication system
*: 5W-30 is an oil that provides optimal levels of fuel efficiency.
Oil viscosity
●5W oils are for use in areas where the ambient temperature is -3F (-25C) or
above. "10W" oils are for areas where the ambient temperature is -4
F (-20C)
or above. Oils with smaller figures are better for engine starting in cold weather
and fuel efficiency.
● XX-30 indicates oil viscosity. Oils with higher numbers have better sta-
bility at higher temperatures and are good for high-speed driving.
