Improper use of the tire jack may cause the vehicle to suddenly fall off the jack,
leading to death or serious injury.
lDo not use the tire jack for any purpose other than replacing tires or installing and
removing tire chains.
lOnly use the tire jack that comes with this vehicle for replacing a flat tire.
Do not use it on other vehicles, and do not use other tire jacks for replacing tires
on this vehicle.
lAlways check that the tire jack is securely set to the jack point.

nReplacing a flat tire
Observe the following precautions to reduce the risk of death or serious injury:
lDo not touch the disc wheels or the area around the brakes immediately after the
vehicle has been driven.
After the vehicle has been driven the disc wheels and the area around the brakes
will be extremely hot. Touching these areas with hands, feet or other body parts
while changing a tire, etc. may result in burns.
lNever use oil or grease on the wheel bolts or wheel nuts.
Oil and grease may cause the wheel nuts to be excessively tightened, leading to
bolt or disc wheel damage. In addition, the oil or grease can cause the wheel nuts

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.
