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 precautions 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.
■Dispose of the hybrid battery (traction battery)
If your vehicle is disposed of without the hybrid battery having been removed, there
is a danger of serious electric shock if high voltage parts, cables and their connec-
tors are touched. In the event of that your vehicle must be disposed of, the hybrid
battery must be disposed of your Lexus dealer or a qualified service shop. If the
hybrid battery is not disposed of properly, they may cause electric shock that can
result in death or serious injury.

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 smart
access system with push-button
start does not operate properly,
you will need the mechanical key.
(→ P. 5 5 0 )
■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

●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. 5 9 , 3 7 3 )
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 4 9 )
■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.

Unlock the doors using the wireless remote control and open one of the
doors.
If a door is not opened within 60 seconds after is pressed, the doors
will be locked again and the alarm will automatically be set.
In case that the alarm is triggered, immediately stop the alarm. (→P. 9 8 )
■Battery-saving function
In the following circumstances, the entry function is disabled in order to prevent the
vehicle and electronic key batteries from discharging.
●When the entry function has not been used for a month or more
●When the electronic key has been left within approximately 3 ft. (1 m) of the
vehicle for 10 minutes or more
The system will resume operation when...
●The vehicle is locked using the door handle lock switch
●The vehicle is locked/unlocked using the wireless remote control function
( → P. 51) or the mechanical key ( →P. 5 5 0 )

●The standard battery life is 1 to 2 years. (The card key battery life is about a year
and a half.)
●The battery becomes depleted even if the electronic key is not used because
the key always transmits radio waves. If the smart access system with push-but-
ton start or the wireless remote control does not operate, or the detection area
becomes smaller, the battery may be depleted. Replace the battery when nec-
essary.
