tem. The LTA system does not automatically drive the vehicle or reduce the amount of attention that
must be paid to the area in front of the vehicle. The driver must always assume full responsibility for driving
safely by paying careful attention to the surrounding conditions and operating the steering wheel to cor-
rect the path of the vehicle. Also, the driver must take adequate breaks when fatigued, such as from
driving for a long period of time.
●Failure to perform appropriate driv-
ing operations and pay careful attention may lead to an accident, resulting in death or serious injury.

WARNING
●The Advanced Park is a system which provides assistance in park-
ing in a set parking space. Depend- ing on the condition of the road surface or the vehicle, the distance
between the vehicle and a parking space, etc., it may not be possible to detect a parking space or the
system may not be able to provide assistance to the point the vehicle is fully parked.
●The Advanced Park is a system which supports the driver when
parking and leaving a parking space. While checking the safety of the area around the vehicle, make
sure to depress the brake pedal as necessary to slow or stop the vehi-cle.
●This system will guide the vehicle to appropriate positions for changing
the direction of travel, however, if you feel that the vehicle is approaching too close to an adja-
cent parked vehicle at any time, depress the brake pedal and change the shift position. However,
if this is performed, the number of times the vehicle changes direction may increase, and the vehicle may
be parked at an angle.
●As following objects may not be
detected, make sure to check the safety of the area around your vehi-cle and depress the brake pedal to
stop the vehicle if it may collide with an object.
• Thin objects such as wire, fences, rope, etc.
• Cotton, snow and other materials that absorb sound waves
• Sharply-angled objects
• Low objects (curb stones, parking
blocks, etc.)
• Tall objects with upper sections that protrude outward
●Even if there is an object in the tar-get parking space, it may not be detected and assistance may be
performed.
●While the system is operating, if it is
likely that your vehicle will collide with a nearby vehicle, parking block, object, or person, depress
the brake pedal to stop the vehicle and press the Advanced Park main switch to disable the system.
●Never use only the Center Display to view the area behind the vehicle.
The image displayed may differ than the actual situation. Using only the screen when backing up may
lead to an accident, such as a colli- sion with another vehicle. When backing up, make sure to look
directly or use the mirrors to check the safety of the area around your vehicle, especially behind the vehi-
cle.
●When the ambient temperature is
extremely low, the screen may appear dark or the displayed image may become unclear. Also, as mov-
ing objects may appear distorted or may not be able to be seen on the screen, make sure to directly check
the safety of the area around your vehicle.
●As the steering wheel will turn while this system is operating, pay atten-tion to the following.
• Be careful so that a necktie, scarf, or arm does not get caught. Keep
your upper body away from the steering wheel. Also, keep children away from the steering wheel.
• Long fingernails may be caught and when the steering wheel is rotating,
leading to injury.
