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 mobile 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.
When left unattended, 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 vehi-
cle. In addition, heat build-up or extremely cold temperatures inside the vehicle can
be fatal to children.

■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.
