OTHER BENEFITS AND ASSISTANCE
strict requirements for training,
equipment, quality and customer
satisfaction. These repair centers
use Genuine Lexus Parts exclusively
in the repair of Lexus vehicles.
The Smart Key
Your Lexus vehicle was made with
two “Smart Keys” and an aluminum
key-number plate. Each Smart Key
includes an electronic main key that
has an integrated mechanical backup
key. The electronic key controls the
remote-entry and theft-deterrent
systems, enables the push-button
start switch and controls the engine
immobilizer. The mechanical key
can be removed from the electronic
key and used to operate the driver’s
door lock, the glove box lock and
the trunk lock (if equipped).
Replacing the Key
Your Lexus dealer can generate
replacement keys. Certain bonded/
registered locksmiths may also be able
to generate replacement keys. When
ordering a new key, bring all keys for
the vehicle to your dealership. If a
Smart Key or the key-number plate is
not available, a Lexus dealer or certain
locksmiths can obtain the key code
from a restricted-access database. These businesses can also access
a service utility to register the keys
to the vehicle if all registered keys
have been lost.
If you lock your key in your vehicle
and do not have a spare, your dealer
can make a new mechanical key
from the code on the key-number
plate. Certain bonded/registered
locksmiths may also be able to
generate a replacement mechanical
key. If a Lexus dealer is not available,
please refer to www.aloa.org to find
a bonded/registered locksmith who
performs high-security key service.
Keeping the Key Safe
Replacing a Smart Key may be costly.
We advise you to keep a spare
Smart Key and the key-number
plate in a safe place. If you record
the key number in more than one
place, do not record it in a way
that can be easily identified and
associated with the vehicle. For
example, don’t leave the number
somewhere that can be accessed
by a valet. It is wise to keep a copy
of the key number outside of
the vehicle.

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.
