cisely controlled in order to help improve
fuel efficiency and reduce exhaust emis-
sions, etc.
There are times when the engine speed that
is displayed may differ even when vehicle
operation and driving conditions are the
same.

lane, which is often associated with a
decrease in the driver’s attention level,
and displays the decrease in attention
using a bar display.
The shorter the bar length, the more
the driver may need to rest.
This display is a part of the LTA (Lane
Tracing Assist) system or LDA (Lane
Departure Alert with steering control)
system. The display is enabled when
the operating conditions of the vehicle
sway warning are met. ( P.221, 230)
■Display off

switch is turned to ON mode. It may also
take a few minutes to display the tire infla-
tion pressure after inflation pressure has
been adjusted.
●“--” may be displayed if the tire informa-
tion cannot be determined due to unfa-
vorable radio wave conditions.
●Tire inflation pressure changes with tem-
perature. The displayed values may also
be different from the values measured
using a tire pressure gauge.

■Cautions during setting up the dis-
play
As the hybrid system needs to be operat-
ing during setting up the display, ensure
that the vehicle is parked in a place with
adequate ventilation. In a closed area
such as a garage, exhaust gases includ-
ing harmful carbon monoxide (CO) may
collect and enter the vehicle. This may
lead to death or a serious health hazard.

3-1.Key information
The following keys are provided with
the vehicle.
Electronic keys
• Operating the smart access system with push-button start ( P.126)
• Operating the wireless remote control function
Mechanical keys
Key number plate
Card key (electronic key) (if
equipped)
Operating the smart access system with
push-button start ( P.126)
■Card key (if equipped)
●The mechanical key that is stored inside
the card key should be used only if a
problem arises, such as when the card
key does not operate properly.
●If the battery cover is not installed and the
battery falls out or if the battery was
removed because the key got wet, rein-
stall the battery with the positive terminal
facing the Lexus emblem.
●The card key is not waterproof.
■When riding in an aircraft
When bringing an electronic key onto an
aircraft, make sure you do not press any
buttons on the electronic key while inside
the aircraft cabin. If you are carrying an
electronic key in your bag, etc., ensure that
the buttons are not likely to be pressed acci-
dentally. Pressing a button may cause the
electronic key to emit radio waves that
could interfere with the operation of the air-
craft.
■Electronic key battery depletion
●The standard battery life is 1 to 2 years.
(The card key battery life is about a year
and a half.)
●If the battery becomes low, an alarm will
sound in the cabin wh en the hybrid sys-
tem stops.
●As the electronic key always receives
radio waves, the battery will become
depleted even if the electronic key is not
used. The following symptoms indicate
that the electronic key battery may be
depleted. Replace the battery when nec-
essary.
• The smart access system with push-but- ton start or the wireless remote control
does not operate.
• The detection area becomes smaller.
• The LED indicator on the key surface does not turn on.
●To avoid serious dete rioration, do not
leave the electronic key within 3 ft. (1 m)
of the following electrical appliances that
produce a magnetic field:

NOTICE
■To prevent key damage
●Do not drop the keys, subject them to
strong shocks or bend them.
●Do not expose the keys to high tem-
peratures for long periods of time.
●Do not get the keys wet or wash them
in an ultrasonic washer, etc.
●Do not attach metallic or magnetic
materials to the keys or place the keys
close to such materials.
●Do not disassemb le the keys.
●Do not attach a sticker or anything else
to the surface of the electronic key.
●Do not place the keys near objects that
produce magnetic fields, such as TVs,
audio systems and induction cookers,
or medical electrical equipment, such
as low-frequency therapy equipment.
■Carrying the electronic key on your
person
Carry the electronic key 3.9 in. (10 cm)
or more away from electric appliances
that are turned on. Radio waves emitted
from electric applianc es within 3.9 in. (10
cm) of the electronic key may interfere
with the key, causing the key to not func-
tion properly.
■In case of a smart access system with
push-button start malfunction or
other key related problems
 P.410
■When an electronic key is lost
 P.409
■Handling the card key
●If the battery or card key terminals get
wet, the battery may corrode and the
card key may stop working.
If the key is dropped into water, or if
drinking water, etc., is spilled on the
key, immediately remove the battery
cover and wipe the battery and termi-
nals. (To remove the battery cover,
lightly grasp and pull it.) If the battery is
corroded, have your Lexus dealer
replace the battery.
●Do not crush the battery cover or use
a screwdriver to remove the battery
cover.
Forcibly removing the battery cover
may bend or damage the key.
●If the battery cover is frequently
removed, the battery cover may
become loose.
●When installing the battery, make sure
to check the direction of the battery.
Installing the battery in the wrong
direction may cause the battery to
deplete rapidly.
●The surface of the card key may be
damaged, or its coating may peel off in
the following situations:
• The card key is ca rried together with
hard objects, such as coins and keys.
• The card key is scraped with a sharp object, such as the tip of a mechanical
pencil.
• The surface of the card key is wiped with thinner or benzene.
