■G-force display
●The G-force values may not be zero even when the vehicle is parked, such as when it is
parked on an incline.
●Depending on the vehicle usage conditions,
the brake fluid pressure display may not
reach its maximum reading even though the brake pedal is fully depressed.

●When the vehicle begins to move
■Tire inflation pressure
●It may take a few minutes to display the tire inflation pressure after the engine switch is
turned to IGNITION 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 information cannot be determined due to unfavorable

■Caution for use while driving
●When operating the multi-information display while driving, pay extra attention to the
safety of the area around the vehicle.

■Cautions during setting up the display
As the engine needs to be operating during setting up the display, ensure that the vehi-
cle is parked in a place with adequate vent ilation. In a closed area such as a garage,
exhaust gases including harmful carbon mo noxide (CO) may collect and enter the
vehicle. This may lead to death or a serious health hazard.

Operation of each component
To take out the mechanical key, push
the release button and take the key out.
The mechanical key can only be
inserted in one direction, as the key only
has grooves on one side. If the key can-
not be inserted in a lock cylinder, turn it
over and re-attempt to insert it.
After using the mechanical key, store it
in the electronic key. Carry the mechan-
ical key together with the electronic key.
If the electronic key battery is depleted
or the entry function does not operate
properly, you will need the mechanical
key. (P. 5 2 0 )
■Card key (if equipped)
●The card key is not waterproof.
●The mechanical key that is st ored inside the card key should be used only if a problem
arises, such as when the card key does not operate properly.
●If it is difficult to take out the mechanical key, push down the lock release button using a
pen tip etc. If it is still difficult to pull it out, use a coin etc.
Using the mechanical key
●To store the mechanical key in the card key,
insert it while pressing the lock release button.
●If the battery cover is not installed and the bat-
tery falls out or if the battery was removed
because the key got wet, reinstall the battery
with the positive terminal facing the Lexus
emblem.

■Panic mode
■When required to leave the vehicle’s key with a parking attendant
Turn the trunk opener main switch off, lock the glove box and armrest door as circum-
stances demand. (
P. 145, 351, 363)
Remove the mechanical key for your own use and provide the attendant with the elec-
tronic key only.
■If you lose your mechanical keys
New genuine mechanical keys can be made by your Lexus dealer using the other
mechanical key and the key number stamped on your key number plate. Keep the plate
in a safe place such as your wallet, not in the vehicle.
■When riding in an aircraft
When bringing an electronic key onto an aircraft, make sure you do not press any but-
tons on the electronic key while inside the airc raft cabin. If you are carrying an electronic
key in your bag etc., ensure that the buttons are not likely to be pressed accidentally.
Pressing a button may cause the electronic key to emit radio waves that could interfere
with the operation of the aircraft.
■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 when the engine stops.
(  P. 4 8 9 )
●As the electronic key always receives ra dio waves, the battery will become depleted
even if the electronic key is not used. The following symptoms indicate that the elec-
tronic key battery may be depleted. Replace the battery when necessary. ( P. 4 2 9 )
• The smart access system with push-button 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 deterioration, do not leave the electronic key within 3 ft. (1 m) of the
following electrical appliances that produce a magnetic field:
•TVs
• Personal computers
• Cellular phones, cordless phones and battery chargers
• Recharging cellular phones or cordless phones
• Table lamps
• Induction cookers
When is pressed for longer than about
one second, an alarm will sound intermittently
and the vehicle lights will flash to deter any per-
son from trying to break into or damage your
vehicle.
To stop the alarm, press any button on the elec-
tronic key.

P. 4 2 9
■Confirmation of the registered key number
The number of keys already registered to the vehicle can be confirmed. Ask your Lexus
dealer for details.
■If a wrong key is used
The key cylinder rotates freely to isolate inside mechanism.
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 temp eratures 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 disassemble 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 pr oduce magnetic fields, such as TVs, audio
systems and induction cookers.
●Do not place the keys near medical electrical equipment such as low-frequency ther-
apy equipment or microwave therapy equipm ent, and do not receive medical atten-
tion with the keys on your person.
■Carrying the electronic key on your person
Carry the electronic key 3.9 in. (10 cm) or mo re away from electric appliances that are
turned on. Radio waves emitted from electric appliances within 3. 9 in. (10 cm) of the
electronic key may interfere with the key, causing the key to not function properly.
■In case of a smart access system with push-button start malfunction or other key-
related problems
Take your vehicle with all the electronic keys provided with your vehicle, including the
card key, to your Lexus dealer.
■When an electronic key is lost
If the electronic key remains lost, the risk of vehicle theft increases significantly. Visit
your Lexus dealer immediately with all rema ining electronic keys and the card key that
was provided with your vehicle.
