tems.

mode to indicate that a system check is
being performed. They will turn off after
the engine is started, or after a few sec-
onds. There may be a malfunction in a
system if a light does not come on, or
turn off. Have the vehicle inspected by
your Lexus dealer.

outside temperature may not be dis-
played, or the display may take longer
than normal to change:
• When stopped, or driving at low speeds (less than 12 mph [20 km/h])
• When the outside temperature has
changed suddenly (at the entrance/exit of
a garage, tunnel, etc.)
●When “_ _”or “E” is displayed, the system
may be malfunctioning.
Take your vehicle to your Lexus dealer.
■Pop-up display
●In some situations, su ch as when a switch
operation is performed, a pop-up display
will be temporarily displayed on the
multi-information display or the odome-
ter/trip meter screen (F SPORT models).
●Some pop-up displays can be set on/off.
(  P.76)
■Customization
The meter display can be customized on
the multi-information display. ( P.351)
■Display items
 Odometer
Displays the total distance the vehicle has
been driven.
Trip meter A/trip meter B
Displays the distance the vehicle has been
driven since the meter was last reset. Trip
meters A and B can be used to record and
display different distances independently.
Distance until next engine oil
change
Displays the distance the vehicle can be
driven until an oil change is necessary.
■Changing the display
Each time the “ODO TRIP” switch is
pressed, the displayed item will be
changed. When the trip meter is dis-
played, pressing and holding the switch
will reset the trip meter.
WARNING
■The information display at low tem-
peratures
Allow the interior of the vehicle to warm
up before using the liquid crystal infor-
mation display. At extremely low tem-
peratures, the in formation display
monitor may respond slowly, and display
changes may be delayed.
For example, there is a lag between the
driver’s shifting and the new gear number
appearing on the display. This lag could
cause the driver to downshift again,
causing rapid and excessive engine brak-
ing and possibly an accident resulting in
death or injury.
NOTICE
■To prevent damage to the engine and
its components
●Do not let the indicator needle of the
tachometer enter the red zone, which
indicates the maximum engine speed.
●The engine may be overheating if the
engine coolant temperature gauge is
in the red zone (H). In this case, imme-
diately stop the vehicle in a safe place,
and check the engine after it has
cooled completely. ( P.322)

●When an interior alarm sounds continu-
ously
■Battery-saving function
The battery-saving fu nction will be acti-
vated in order to prevent the electronic key
battery and the vehicle battery from being
discharged while the vehicle is not in opera-
tion for a long time.
●In the following situations, the smart
access system with pu sh-button start may
take some time to unlock the doors.
• The electronic key has been left within approximately 6 ft. (2 m) of the outside of
the vehicle for 10 minutes or longer.
• The smart access system with push-but- ton start has not been used for 5 days or
longer.
●If the smart access system with push-but-
ton start has not been used for 14 days or longer, the doors cann
ot be unlocked at
the passenger door. In this case, take hold
of the driver’s door handle, or use the
wireless remote control or mechanical
key, to unlock the doors.
■Electronic Key Battery-Saving Function
When battery-saving mode is set, battery
depletion is minimized by stopping the elec-
tronic key from receiving radio waves.
Press twice while pressing and holding
. Confirm that the electronic key indica-
tor flashes 4 times.
While the battery-saving mode is set, the
smart access system with push-button start
cannot be used. To cancel the function,
press any of the electronic key buttons.
■Conditions affecting operation
The smart access system with push-button
start uses weak radio waves. In the following
situations, the communication between the
electronic key and the vehicle may be
affected, preventing the smart access sys-
tem with push-button start, wireless remote
control and engine immobilizer system
from operating properly.
(Ways of coping: P.317)
●When the electronic key battery is
depleted
●Near a TV tower, electric power plant,
gas station, radio stat ion, large display,
airport or other fac ility that generates
strong radio waves or electrical noise
●When carrying a portable radio, cellular
phone, cordless phone or other wireless
communication device
●When the electronic key is in contact
with, or is covered by the following metal-
lic objects
• Cards to which aluminum foil is attached
SituationCorrection
procedure
The trunk was closed
while the electronic key
was still inside the trunk
and both side doors were
locked.Retrieve the
electronic key
from the trunk
and close the
trunk lid.
An attempt was made to
lock the vehicle while a
door was open.Close both
side doors and
lock the doors
again.
SituationCorrection procedure
The engine switch was
turned to ACCESSORY
mode while the driver’s
door was open (or the
driver’s door was opened
while the engine switch
was in ACCESSORY
mode).
Turn the engine
switch off and
close the
driver’s door.
The engine switch was
turned off while the

Before driving
• Cigarette boxes that have aluminum foil
inside
• Metallic wallets or bags
•Coins
• Hand warmers made of metal
• Media such as CDs and DVDs
●When other wireless ke ys (that emit radio
waves) are being used nearby
●When carrying the electronic key
together with the following devices that
emit radio waves
• Another vehicle’s electronic key or a wireless key that emits radio waves
• Personal computers or personal digital assistants (PDAs)
• Digital audio players
• Portable game systems
●If window tint with a metallic content or
metallic objects are attached to the rear
window
●When the electronic key is placed near a
battery charger or electronic devices
■Note for the entry function
●Even when the electronic key is within the
effective range (detection areas), the sys-
tem may not operate properly in the fol-
lowing cases:
• The electronic key is too close to the win- dow or outside door handle, near the
ground, or in a high place when the doors
are locked or unlocked.
• The electronic key is near the ground or
in a high place, or too close to the rear
bumper center when the trunk is opened.
• The electronic key is on the instrument
panel, rear package tray or floor, or in the
door pockets or glove box when the
engine is started or engine switch modes
are changed.
●Do not leave the electronic key on top of
the instrument panel or near the door
pockets when exiting the vehicle.
Depending on the radio wave reception
conditions, it may be detected by the
antenna outside the cabin and the doors
will become lockable from the outside,
possibly trapping the electronic key
inside the vehicle.
●As long as the electron ic key is within the
effective range, the doors may be locked
or unlocked by anyone. However, only the doors detecting the electronic key
can be used to unlock the vehicle.
●Even if the electronic
key is not inside the
vehicle, it may be po ssible to start the
engine if the electronic key is near the
window.
●The doors may unlock or lock if a large
amount of water splashes on the door
handle, such as in the rain or in a car
wash, when the electronic key is within
the effective range. (The doors will auto-
matically be locked after approximately
60 seconds if the doors are not opened
and closed.)
●If the wireless remote control is used to
lock the doors when the electronic key is
near the vehicle, there is a possibility that
the door may not be unlocked by the
entry function. (Use the wireless remote
control to unlock the doors.)
●Touching the door lock or unlock sensor
while wearing gloves may prevent lock or
unlock operation.
●When the lock operation is performed
using the lock sensor, recognition signals
will be shown up to two consecutive
times. After this, no recognition signals
will be given.
●If the door handle becomes wet while the
electronic key is within the effective
range, the door may lock and unlock
repeatedly. In this case, follow the follow-
ing correction procedures to wash the
vehicle:
• Place the electronic key in a location 6 ft. (2 m) or more away from the vehicle.
(Take care to ensure that the key is not
stolen.)
• Set the electronic key to battery-saving
mode to disable the smart access system
with push-button start. ( P.96)
●If the electronic key is inside the vehicle
and a door handle becomes wet during a
car wash, a message may be shown on
the multi-information display and a
buzzer will sound outside the vehicle. To
turn off the alarm, lock both side doors.
●The lock sensor may not work properly if
it comes into contact with ice, snow, mud,
etc. Clean the lock sensor and attempt to
operate it again.
