How to use the camera ●
The Multi-terrain Monitor system may not operate properly in the following cases.
• If the front or the rear of the vehicle or the outside rear view mirror has been hit,
the camera’s position and mounting angle may have changed.
• As the camera has a water proof construction, do not detach, disassemble or
modify it. This may ca use incorrect operation.
• When cleaning the camera lens, flush the camera with a large quantity of water
and wipe it with a soft and wet cloth. Strongly rubbing the camera lens may cause
the camera lens to be scratched and unable to transmit a clear image.
• Do not allow organic solvent, car wax, window cleaner or glass coat to adhere to
the camera. If this happens, wi pe it off as soon as possible.
• If the temperature changes rapidly, such as when hot water is poured on the vehi-
cle in cold weather, the system may not operate normally.
• When washing the vehicle, do not apply intensive bursts of water to the camera or
camera area. Doing so may result in the camera malfunctioning.
• When the camera is used under fluorescen t lights, sodium light or mercury light
etc., the lights and the illuminated areas may appear to flicker.

The areas that vehicles can be detected in are outlined below.
The range of each detection area is:
Approximately 1.6 ft. (0.5 m) to 11.5 ft. (3 .5 m) from either side of the vehicle
*
* : The area between the side of the vehicle and 1.6 ft. (0.5 m) from the side of the vehicle
cannot be detected.
Approximately 3.3 ft. (1 m) forward of the rear bumper
Approximately 9.8 ft. (3 m) from the rear bumper
Approximately 9.8 ft. (3 m) to 197 ft. (60 m) from the rear bumper
*
* : The greater the difference in speed betwee n your vehicle and the detected vehicle is,
the farther away the vehicle will be detect ed, causing the outside rear view mirror

WARNING ■
Cautions regarding the use of the function
The driver is solely responsible for safe driving. Always drive safely, taking care to
observe your surroundings.
The BSM function is a supplementary function which alerts the driver that a vehicle is in
a blind spot of the outside rear view mirrors or is approaching rapidly from behind into
a blind spot. Do not overly rely on the BSM function. As the function cannot judge if it is
safe to change lanes, over reliance could lead to an accident resulting in death or seri-
ous injury.
As the system may not function correctly under certain conditions, the driver’s own
visual confirmation of safety is necessary. 1

Conditions under which the BSM function may not function correctly ●
The BSM function may not detect vehicles correctly in the following situations:
• When the sensor is misaligned due to a stro ng impact to the sensor or its surround-
ing area
• When mud, snow, ice, a sticke r, etc. is covering the sensor or surrounding area on
the rear bumper
• When driving on a road surf ace that is wet with standi ng water during bad weather,
such as heavy rain, snow, or fog
• When multiple vehicles are approaching wi th only a small gap between each vehicle
• When the distance between your vehicle and a following vehicle is short
