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 judg-
ment 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 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.

Safety information for children
It is recommended that children sit in the rear seats to avoid acci-
dental contact with the shift lever, wiper switch etc.
Use the rear door child-protector lock or the window lock switch
to avoid children opening the door while driving or operating the
power window accidentally.
Do not let small children operate equipment which may catch or
pinch body parts, such as the power window, hood, trunk, seats
etc.
Observe the following precautions when children are in the vehi-
cle.
Use a child restraint system appropriate for the child, until the
child becomes large enough to properly wear the vehicle’s seat
belt.
CAUTION
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

GS350/250_EE (OM30C36E)
Canceling and automatic re-enabling of the intrusion sensor and tilt sensor
The alarm will still be set even when the intrusion sensor and tilt sensor are
canceled.
After the intrusion sensor and tilt sensor are canceled, pressing the engine
switch or unlocking the doors using the entry function, wireless remote con-
trol or mechanical key will re-enable the intrusion sensor and tilt sensor.
The intrusion sensor and tilt sensor will automatically be re-enabled when
the alarm system is deactivated.
Intrusion sensor detection considerations
The sensor may trigger the alarm in the following situations:
Places with extreme vibrations or noises, or situations in which the vehicle
is subject to repeated impacts or vibrations:
• When parked in a parking garage
• When the vehicle is transported by a ferry, trailer, train, etc.
• When ice adhering to the vehicle is removed
• When the vehicle is in an automatic or high-pressure car wash
• When in a hail or lightning storm
A window or the moon roof is open.
In this case, the sensor may detect the
following:
• Wind or the movement of objects
such as leaves and insects inside the
vehicle
• Ultrasonic waves emitted from
devices such as the intrusion sensors
of other vehicles
• The movement of people outside the
vehicle
Unstable items, such as dangling acces-
sories or clothes hanging on the coat
hooks, are in the vehicle.
