nEngine oil selection
“Toyota Genuine Motor Oil” is used in your Lexus vehicle. Use Lexus
approved “Toyota Genuine Motor Oil” or equivalent to satisfy the follow-
ing grade and viscosity.
Oil grade: ILSAC multigrade engine oil
Recommended viscosity: SAE 0W-20
SAE 0W-20 is the best choice for
good fuel economy and good
starting in cold weather.
If SAE 0W-20 is not available,
SAE 5W-20 oil may be used.
However, it must be replaced with
SAE 0W-20 at the next oil
change.
The 0W portion of the oil viscosity rating indicates the characteristic of the oil
which allows cold startability. Oils with a lower value before the W allow for eas-
ier starting of the engine in cold weather.
The 20 in 0W-20 indicates the oil viscosity when the oil is at its operating tem-
perature. An oil with a higher viscosity may be better suited if the vehicle is oper-
ated at high speeds, or under extreme load conditions.

Introduction
THE IMPORTANCE OF SCHEDULED MAINTENANCE

MAINTENANCE
39
Regular maintenance is essential
to obtaining the highest level of per-
formance, safety and reliability from
your Lexus. It can also enhance your
vehicle’s resale value. This section
of the Warranty and Services Guide
is designed to help you make sure
your vehicle receives proper and
timely maintenance. It includes
factory-recommended maintenance
guidelines as well as logs in which to
document your vehicle’s maintenance
history.
In addition to scheduled maintenance,
your Lexus requires ongoing general
maintenance such as fluid checks and
visual inspections. These procedures
are listed on pages 42–43 of this
booklet and described in detail in
the “Maintenance” section of the
Owner’s Manual.
It is especially important to check
your vehicle’s engine oil once a
month and to regularly replace the
engine oil and oil filter. Failure to do
so can cause oil starvation and/or oil
gelling, which can result in severe
damage to your vehicle and require
costly repairs that are not covered by
the New Vehicle Limited Warranty.
With proper maintenance and care,
your vehicle will last longer and deliv-
er more dependable, economical
performance. Follow this booklet’s
recommendations and you’ll enjoy
maximum reliability and peace of
mind from your Lexus for many years
to come.

Introduction
GENERAL MAINTENANCE AND REGULAR USE
MAINTENANCE
42
In addition to scheduled maintenance,
your Lexus requires ongoing general
maintenance such as fluid checks and
visual inspections. The recommended
guidelines for inspections are listed
below. Please refer to the “Mainte-
nance” section of the Owner’s Manual
for a detailed description of inspec-
tion procedures.
Every 30 Days
At least once every 30 days, perform
these inspections:
•Check engine oil level using
the dipstick
•Visually check engine coolant
level on the see-through
reservoir
•Visually check brake fluid level
on the see-through reservoir
•Visually check condition of
battery
•Check level of windshield
washer fluid
•Check tire pressure
•Check tires for damage
and wear
•Check installation of driver’s
floor mat
After a Car Wash
•Check installation of driver’s
floor mat
After Off-Road Driving
Whenever you drive off-road through
deep sand, mud or water, perform
these inspections daily:
•Check axle shaft boots
•Check ball joints and dust covers
•Check brake lines and hoses
•Check brake pads/rotors and
parking brake linings/drums
•Check differential oil
•Check engine air filter
•Check nuts and bolts on chassis
•Check steering linkage and
boots
•Check transfer case oil
(AWD models)

Determining Your
Maintenance Interval:
Months vs. Mileage
Lexus recommends obtaining sched-
uled maintenance for your vehicle
every six months or 5,000 miles,
whichever occurs first.
For example:
•If at six months you have driven
less than 5,000 miles, you
should obtain maintenance at six
months; don’t wait until 5,000
miles.
•If you drive 5,000 miles in less
than six months, you should
obtain maintenance at 5,000
miles; don’t wait until six months.
Be sure to keep an eye on your
mileage so that you obtain mainte-
nance when recommended. If you are
a low-mileage driver, mark your cal-
endar to remind yourself to obtain
maintenance every six months.
Special Operating
Conditions
In addition to standard maintenance
items, vehicles that are driven under
special operating conditions require
further maintenance service. These
special operating conditions, which
put added demands on a vehicle,
include:
•Driving on dirt roads or on dusty
roads
•Repeated trips of less than five
miles in temperatures below
32° F or 0° C
•Extensive idling and/or low-
speed driving for long distances,
such as police, taxi or door-to-
door delivery use
If you drive primarily under any
of the conditions noted, you
should replace the engine oil
and oil filter every six months or
5,000 miles. Some of these
special operating conditions
require other maintenance items;
these items are indicated in each
maintenance chart.
