Lexus GS350 2015 Warranty and Services Guide

39 Introduction
THE IMPORTANCE OF SCHEDULED MAINTENANCE
MAINTENANCE
Regular maintenance is essential
to obtaining the highest level of
performance, 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 deliver 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.

MAINTENANCE AND LEXUS WARRANTY COVERAGE
MAINTENANCE
Maintaining your vehicle according
to the recommendations in this
booklet is required to ensure that
your warranty coverage remains
intact. You should keep detailed
records of vehicle maintenance,
including date of service, mileage
at time of service and a description
of service and/or parts installation
performed. The maintenance logs
in this booklet are a good place to
record this information. If you sell
your vehicle, be sure to give your
maintenance records to the
new owner.
Lexus will not deny a warranty claim
solely because you do not have records
to show that you maintained your
vehicle. However, damage or failures
caused by lack of proper maintenance
are not covered under warranty.Maintenance and repair services may
be performed by you or by any auto-
motive service provider you choose.
Lexus will not deny a warranty claim
solely because you used a service
provider other than a Lexus dealer-
ship for maintenance and repairs.
However, damage or failures caused
by improper maintenance or repairs
are not covered under warranty.
Your dealer may recommend more
frequent maintenance intervals or
more maintenance services than
those listed in the scheduled mainte-
nance log. These additional services
are not required to maintain your
warranty coverage. Ask your dealer
for an explanation of any recom-
mended maintenance not included
in the scheduled maintenance log.
For a complete description of
Lexus warranty coverages, see
pages 16–33 of this booklet.

41 Introduction
LEXUS DEALERSHIP SERVICE
MAINTENANCE
To ensure that your vehicle receives
first-quality service and factory-
authorized parts, Lexus recommends
having maintenance performed by
an authorized Lexus dealership. To
locate your nearest authorized Lexus
dealership, log on to www.lexus.com or
contact Lexus Customer Satis faction
at (800) 255-3987.
Lexus dealership technicians are
experts in the maintenance and repair
of Lexus vehicles. They stay current on
the latest service information through
Lexus technical bulletins, service
publications and training courses.
Many are also certified through the
Lexus Commitment to Perfection
Certification Program, which requires
specialized, state-of-the-art training
as well as rigorous exams through
both Lexus and the National Institute
for Automotive Service Excellence.Additionally, when you have your
vehicle serviced at a Lexus dealership,
your service information is recorded
in the Lexus National Service
History database. This is the first
database of its kind in the automotive
industry. It can be accessed by any
Lexus dealership in the U.S. —
a great convenience if you relocate or
need to have your vehicle serviced
while traveling.
You can be confident you’re
getting the best possible service
for your vehicle when you take it
to a Lexus dealership. Don’t trust
your investment to anything less
than a team of Lexus specialists.

Maintenance and repairs not
performed by an authorized
Lexus dealership should be
performed by a qualified technician
following procedures in Lexus
service and repair publications.

GENERAL MAINTENANCE AND REGULAR USE
MAINTENANCE
In addition to scheduled maintenance,
your Lexus requires ongoing general
maintenance such as fluid checks
and visual inspections. The recom-
mended guidelines for inspections
are listed below. Please refer to
the “Mainte nance” section of the
Owner’s Manual for a detailed
description of inspection 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
When Cleaning the Interior
• Remove dirt and dust with a
vacuum cleaner. Wipe dirty
surfaces with a soft cloth
dampened with warm water.
• When cleaning leather interior,
remove dirt and dust with a
vacuum cleaner. Using a
sponge, apply a small amount
of neutral wool detergent mixed
in water, rubbing in a circular
motion. Wipe off any excess
detergent and let leather dry
in an open-air location.
• When cleaning carpet, remove dirt
and dust with a vacuum cleaner.
Apply a foaming-type carpet
cleaner with a sponge or brush,
allowing cleaner to work for a few
minutes to loosen dirt. Continue by
rubbing carpet in a circular motion.
Wipe off any excess cleaner with
a clean cloth. If any dirt remains,
repeat process. Best results are
obtained by keeping the carpet as
dry as possible.

43 Introduction
GENERAL MAINTENANCE AND REGULAR USE
MAINTENANCE
When Cleaning the Exterior
• Working from top to bottom,
apply lots of low-pressure water
to the body, wheel wells and
underside of vehicle to remove
dirt and dust. Wash the vehicle
body using a soft sponge or
cotton cloth with mild car-wash
soap. Rinse off with water.
• If water does not bead on a clean
vehicle surface, apply car wax
using a soft cotton cloth when
the body of the vehicle is cool.
When Cleaning the Wheels
• Wait for hot wheels to cool
before getting wheels wet.
• Using a soft sponge or cotton
cloth, apply same mild car-wash
soap as used for the vehicle body.
Quickly rinse off with water. Using
a soft cotton cloth, apply same car
wax as used for the vehicle body.

Determining Your
Maintenance Interval:
Months vs. Mileage
Lexus recommends obtaining
scheduled 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 mainte-
nance 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
calendar 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
• Towing. Not all vehicles are
designed for towing. Please
refer to the Owner’s Manual
for details.
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.
