Improper use of vehicle keys can result in serious personal injury.
Always take the key with you when you leave the vehicle. The
engine can be started and vehicle systems such as the power
windows can be operated, leading to serious personal injury.
Never leave children, disabled persons, or anyone who cannot
help themselves in the vehicle. The doors can be locked with
the remote control vehicle key. This could result in people
being trapped in the vehicle in an emergency. For example,
depending on the time of year, people trapped in the vehicle
can be exposed to very high or very low temperatures.
Heat buildup in the passenger and luggage compartment of a
parked vehicle can result in temperatures in the vehicle that
are much higher than the outside temperatures, particularly in
summer. Temperatures can quickly reach levels that can
cause unconsciousness and death, particularly to small
children.
Never remove the key from the ignition switch while the
vehicle is moving or rolling to a stop. The steering wheel will
lock and you will not be able to steer or control the vehicle.
