Maintenance and care
IS F_EE
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
frequent 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
accurately.
Oil consumption: Max. 1.0 L per 1000 km (1.1 qt./600 miles, 0.9 Imp.
qt./600 miles)
If your vehicle consumes more than 1.0 L (1.1 qt., 0.9 Imp. qt.) every
1000 km (600 miles), contact any authorized Lexus dealer or repairer, or
another duly qualified and equipped professional.
CAUTION
Used engine oil
Used engine oil contains potentially harmful contaminants which may
cause skin disorders such as inflammation 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 dispose of used oil and filters in household trash, in sewers or onto the
ground.
Call any authorized Lexus dealer or repairer, or another duly qualified and
equipped professional, service station or auto parts store for information
concerning recycling or disposal.
Do not leave used engine oil within the reach of children.

IS F_EE
Checking interval
Inspect and replace the air conditioning filter according to the maintenance
schedule. In dusty areas or areas with heavy traffic flow, early replacement
may be required. (For scheduled maintenance information, please refer to
the “Lexus Service Booklet” or “Lexus Warranty Booklet”.)
If air flow from the vents decreases dramatically
The filter may be clogged. Check the filter and replace if necessary.
Cleaning method
If the filter is dirty, clean by
blowing compressed air
through the filter from the
downward side.
Hold the air gun 5 cm (2 in.)
from the filter and blow for
approximately 2 minutes at
500 kPa (5.0 kgf/cm
2 or bar,
72 psi).
If it is not available, have the
filter cleaned by any autho-
rized Lexus dealer or
repairer, or another duly
qualified and equipped pro-
fessional.
Replacement method
Remove the air conditioning
filter from the filter case and
replace it with a new one.
The “UP” marks shown on
the filter and the filter case
should be pointing up.

If your vehicle needs to be towed
Before towing
The following may indicate a problem with your transmission.
Contact any authorized Lexus dealer or repairer, or another duly
qualified and equipped professional, before towing.
The engine is running, but the vehicle will not move.
The vehicle makes an abnormal sound.
Emergency towing
If a tow truck is not available, in an emergency your vehicle may
be temporarily towed using a cable or chain secured to the emer-
gency towing eyelet. This should only be attempted on hard, sur-
faced roads for short distances at low speeds.
A driver must be in the vehicle to steer and operate the brakes. The
vehicle’s wheels, drive train, axles, steering and brakes must be in
good condition.
If towing is necessary, we recommend having your vehicle towed by
any authorized Lexus dealer or repairer, or another duly qualified and
equipped professional, such as a commercial towing service, using a
lift-type truck or a flat bed truck.
Use a safety chain system for all towing, and abide by all state/provin-
cial and local laws.
If towing from the rear, the vehicle's front wheels and axles must be in
good condition. (P. 421)
If they are damaged, use a towing dolly or flat bed truck.
