What to do in the case of an extremely critical
situation wherein someone may suffer grave
or mortal injury.
DO NOT PROCEED TO BACK UP YOUR VEHICLE WHILE
PEOPLE ARE IN YOUR VIEW OR THE CAMERA’S VIEW.
SERIOUS INJURY OR DEATH CAN RESULT.
WARNING
This symbol means important instructions.
Failure to heed them can result in serious
injury or death.
WHEN USING SYSTEM, THE DRIVER MUST VISUALLY
CHECK ACTUAL CONDITIONS AROUND THE VEHICLE.
MAKE SURE THERE ARE NO PERSONS OR ANIMALS
IN THE AREA IN WHICH YOU ARE MANEUVERING
OTHERWISE YOU COULD INJURE THEM.
A camera assists the driver by sending images to the screen
showing conditions in view of the camera. The camera uses
a wide-angle lens, therefore, there is a difference in distance
perspective between what is normally seen and what appears
on the screen. Also, the images shown by the rear view camera
are reversed, so as to appear the same as what is seen through
the rearview mirror.
The system may not perform to full capability due to
variables such as:
• weather conditions such as hard rain, snow, fog or mud
• extremely high or low temperatures near camera and/
orsensor
• slope of vehicle and/or roadway
• direct exposure to very bright light such as headlamp or
bright sunlight
• moving from very dark to very bright light and vice versa
such as in parking garages or tunnels
• extremely low light areas
• walls or objects that are located diagonally in relation to
the camera
• retracted mirrors that change camera viewing angle
• open doors or trunks
• changes to height of vehicle due to loading capacity or
hydraulic suspensions
• objects located at the corner of the vehicle

etc. and results in serious accident.
DO NOT DAMAGE PIPE OR WIRING WHEN DRILLING
HOLES.
When drilling holes in the chassis for installation, take
precautions so as not to contact, damage or obstruct pipes,
fuel lines, tanks or electrical wiring. Failure to take such
precautions may result in fire.
DO NOT USE BOLTS OR NUTS IN THE BRAKE OR
STEERING SYSTEMS TO MAKE GROUND CONNECTIONS.
Bolts or nuts used for the brake or steering systems (or any
other safety-related system), or tanks should NEVER be used
for installations or ground connections. Using such parts
could disable control of the vehicle and cause fire etc.
2-EN

This system uses ultrasonic sensors to help sharpen the
driver’s detection of obstacles. It is used when parking in a
garage or a narrow passage. As such, this system does not
relieve the driver of the obligation to pay attention to his/
her driving, and the driver should exercise safe driving habits
without relying heavily on this system. The detection range
of the Visual Parking Assist Sensor System (VPASS system) is
restricted to the area around the bumper. When moving the
car either forward or backward, drive slowly and keep a safe
distance around the vehicle. To ensure the sensors function
accurately, never install accessories in close proximity to the
sensors.
1The detecting function might not
operate properly under the following
conditions:
• When the detection sensors become frozen. (Normal
function resumes after defrosting.)
3-EN
• When the detection sensors are clogged with foreign matter
such as show, mud or icicles. (Normal function resumes
after removal.)
• When a detection sensor is subject to a strong impact.
2The detecting range could decrease
under the following conditions:
• When the vehicle is parked for a long period of time in the
sunlight or in cold weather.
3The Parking Corner Sensor might
not be able to detect the following
objects:
• Rope, wire, small-diameter pipes or objects made of these
materials, such as wire fences.
• Objects that absorb sound waves easily, such as fabrics or
other soft, absorbent materials.
• When a sensor is covered by something. (The function
resumes after removal.)
• When the detection sensors are clogged with mud, snow
or icicles.
4-EN
• When the vehicle is parked at extreme angles in relation to
surrounding objects.
• When getting too close to an obstacle (< 0.7ft) as the
sensors might have a false detection; for example: no beep,
slow beep, fast beep or three fast beeps.
• Objects around the lower part of the bumper. Even if the
sensors detect a low object initially, when the vehicle is
driven closer to the object, the buzzer might suddenly stop
beeping.
Obstacles being lowered from above, such as a garage door.
• Non-reflecting objects that project at sharp or acute angles
in relation to the sensors.
• Heavy rain or a large amount of water (or splash) on the
sensors.
Caring for the Backup Sensors
1. Wipe the sensors clean with a clean cloth. Flush with lowpressure water if the sensors are clogged with mud or dirt.
2. Do not spray the sensors with high-pressure water, as
provided at a self-serve car wash.
Obstacles that project out high above the floor.
NOTICE
• When washing the vehicle, do not use an automatic car
washer, or high-pressure washer. Doing so could cause the
camera and/or object sensor to come off, damage to the
device cords, or may allow water to enter the camera and/
or object sensor.
• In some cases, to attach the device, a hole must be drilled
in the car body, requiring use of touch-up paint (retail
product) for rust-prevention, and should be prepared
beforehand.
• Route the cables and wiring away from hot or moving
parts, and fix them securely to avoid heat/mechanical
damage to the cable insulation, which may result in shortcircuit, fire or electric shock.

Sensor Operation
Introduction
Thank you for purchasing this Visual Parking
Assist Sensor System (VPASS system). Please read
this User’s Information Manual carefully before
using the VPASS system.
This Owners Manual contains important
information about the safe operation of the
VPASS system. We urge you to read this manual
carefully, and follow its recommendations to help
make your driving trouble-free and enjoyable.
Important Information
Before using the backup sensors, make sure
you read and understand the operation and
limitations of the system as discussed throughout
this manual.
The backup sensors make an audible sound
when they detect large stationary objects while
maneuvering the vehicle in reverse gear at low
speed. However, not all obstacles may be detected.
Even with backup sensors, the driver should
always look for obstacles near the vehicle and
make sure the path is clear when driving in
reverse gear.
Never rely solely on the backup sensors; always
look behind you before backing up. The sensors
may not always detect people or animals in the
path of your vehicle.
How the Visual Parking Assist
Sensor System Works
The system is ready for operation when the
ignition switch is turned ON and the shift lever is
moved to the reverse position.
The visual parking assist sensor system alerts
you with an audible signal and visual alert when
the rear bumper of your vehicle is approaching an
obstacle.
