CAUTION
■General precautions while driving
Driving under the influence: Never drive your vehicle when under the influence of
alcohol or drugs that have impaired your ability to operate your vehicle. Alcohol
and certain drugs delay reaction time, impair judgment and reduce coordination,
which could lead to an accident that could result in death or serious injury.
Defensive driving: Always drive defensively. Anticipate mistakes that other drivers
or pedestrians might make and be ready to avoid accidents.
Driver distraction: Always give your full attention to driving. Anything that distracts
the driver, such as adjusting controls, talking on a cellular phone or reading can
result in a collision with resulting death or serious injury to you, your occupants or
others.
■General precaution regarding children’s safety
Never leave children unattended in the vehicle, and never allow children to have or
use the key.
Children may be able to start the vehicle or shift the vehicle into neutral. There is
also a danger that children may injure themselves by playing with the cigarette
lighter, the windows, the moon roof, or other features of the vehicle. In addition, heat
build-up or extremely cold temperatures inside the vehicle can be fatal to children.

Using the mechanical keyTake out the mechanical key.
The mechanical key can only be
inserted in one direction, as the key
only has grooves on one side. If the
key cannot 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 mechanical 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. 505)
■Card key
●The mechanical key that is stored inside the card key should be used only if a
problem arises, such as when the 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 difficult to pull it out, use a coin etc.
●To store the mechanical key in the card
key, insert it inside while pressing the
lock release button.

●The card key is not waterproof.
■When required to leave a key to the vehicle with a parking attendant
Turn the trunk opener main switch off and lock the glove box as circumstances
demand. (→P. 47, 333)
Remove the mechanical key for your own use and provide the attendant with the
electronic key only.
■Key number plate
Keep the plate in a safe place such as your wallet, not in the vehicle. In the event that
a mechanical key is lost, a new key can be made at your Lexus dealer using the key
number plate. ( →P. 5 0 4 )
■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
accidentally. Pressing a button may cause the electronic key to emit radio waves
that could interfere with the operation of the aircraft.
●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 termi-
nal facing the Lexus emblem.

NOTICE
■To prevent key damage
Observe the following.
●Do not drop the keys, subject them to strong shocks or bend them.
●Do not expose the keys to high temperatures for a long period 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 electronic keys.
●Do not place the keys near objects that produce magnetic fields, such as TVs,
audio systems, glass top ranges, or medical electrical equipment, such as low-fre-
quency therapy equipment.
■Precautions for handling the card keys
●Do not apply excess force when inserting the mechanical key to the card key.
Doing so may damage 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 terminals. (To
remove the battery cover, lightly grasp it and pull.) 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 rap-
idly.
●The surface of the card key may be damaged, or its coating may peel off in the
following situations.
• The card key is carried together with hard objects, such as coins or keys.
• The card key is scraped with a sharp object, such as a tip of mechanical pencil.
• The surface of the card key is wiped with thinners or benzene.
