Adjusting the height of rear view mirror
Adjust the height of the rear view
mirror by moving it up and down.
■To prevent sensor error (vehicles with auto anti-glare inside rear view
mirror)
CAUTION
■ Caution while driving

■Conditions that may trigger the system even if there is no possibility of
a collision
● When there is an object by the roadside at the entrance to a curve
● When passing an oncoming vehicle on a curve
● When driving over a narrow iron bridge
● When there is a metal object on the road surface
● When driving on an uneven road surface
● When passing an oncoming vehicle on a left-turn
● When your vehicle rapidly closes on the vehicle in front
● When a grade separation/interchange, sign, billboard, or other structure
appears to be directly in the vehicle’s line of travel
● When climbing a steep hill or going down a downhill slope causes an
overhead billboard or other metallic structure to appear directly in the
vehicle’s line of travel
● When there are excessive changes in the vehicle height (when it tilts for-
wards or backwards)
● When passing through an electronic toll collection gate (only in countries
with electronic toll collection)
● When the axis of the radar is out of adjustment
● When passing through the overpass
When the system is activated in the situations described above, there is also
a possibility that the seat belts will retract quickly and the brakes will be
applied with a force greater than normal. When the seat belt is locked in the
retracted position, stop the vehicle in a safe place, release the seat belt and
refasten it.
■ Obstacles not detected
The sensor cannot detect plastic obstacles such as traffic cones. There may
also be occasions when the radar sensor cannot detect pedestrians, ani-
mals, bicycles, motorcycles, trees, or snowdrifts.

■Situations in which the pre-collis ion system does not function properly
The system may not function effectively in situations such as the following:
● On roads with sharp bends or uneven surfaces
● If a vehicle suddenly moves in front of your vehicle, such as at an inter-
section
● If a vehicle suddenly cuts in front of your vehicle, such as when overtak-
ing
● In inclement weather such as heavy rain, fog, snow or sand storms
● When your vehicle is skidding such as the VSC system off
● When an extreme change in vehicle height occurs
● When the axis of the radar is out of adjustment
■ Automatic cancelation of the pre-collision system
When a malfunction occurs due to sensor contamination, etc. that results in
the sensors being unable to detect obstacles, the pre-collision system will be
automatically disabled. In this case, the system will not activate even if there
is a collision possibility.
■ When there is a malfunction in the system
Warning lights and warning messages will turn on or flash. ( P. 745)

■Conditions under which the Blind Spot Monitor function may not func-
tion correctly
● The Blind Spot Monitor function may not detect vehicles correctly in the
following conditions:
• During bad weather such as heavy rain, fog, snow etc.
• When ice or mud etc. is attached to the rear bumper
• When driving on a road surface that is wet due to rain, standing water
etc.
• When there is a significant difference in speed between your vehicle and the vehicle that enters the detection area
• When a vehicle is in the detection area from a stop and remains in the detection area as your vehicle accelerates
• When driving up or down consecutive steep inclines, such as hills, a dip in the road etc.
• When multiple vehicles approach with only a small gap between each vehicle
• When vehicle lanes are wide, and the vehicle in the next lane is too far away from your vehicle
• When the vehicle that enters the detection area is traveling at about the same speed as your vehicle
• When there is a significant difference in height between your vehicle and the vehicle that enters the detection area
• Directly after the BSM main switch is set to on
• When towing a trailer
• When items such as a bicycle carrier are installed on the rear of the vehicle
● Instances of the Blind Spot Monitor function unnecessarily detecting a
vehicle and/or object may increase under the following conditions:
• When there is only a short distance between your vehicle and a guard-
rail, wall etc.
• When there is only a short distance between your vehicle and a follow- ing vehicle
• When vehicle lanes are narrow and a vehicle driving 2 lanes across from your vehicle enters the detection area
• When items such as a bicycle carrier are installed on the rear of the vehicle

Trailer Tongue Weight
● A recommended tongue weight varies in accordance with the types
of trailers or towing as described below.
● To ensure the recommended values shown below, the trailer must
be loaded by referring to the following instructions.
• Tongue Weight
The gross trailer weight should be distributed so that the tongue
weight is 9 to 11 %.
(Tongue weight / Gross trailer weight  100 = 9 to 11 %)
Gross trailer weight
Tongue weight
If using a weight distributing hitch when towing, return the front
axle to the same weight as before the trailer connection.
If front axle weight cannot be measured directly, measure the front
fender height above the front axle before connection. Adjust weight
distributing hitch torque until fr ont fender is returned to the same
height as before connection.
The gross trailer weight, gross axle weight and tongue weight can
be measured with platform scales found at a highway weighing sta-
tion, building supply company, trucking company, junk yard, etc.

Matching trailer ball height to trailer coupler height
■ Before towing
Check that the following conditions are met:
● Ensure that your vehicle’s tires are properly inflated. ( P. 810)
● Trailer tires are inflated according to the trailer manufacturer’s recom-
mendation.
● All trailer lights work as required by law.
● All lights work each time you connect them.
● The trailer ball is set at the proper height for the coupler on the trai\
ler.
● The trailer is level when it is hitched.
Do not drive if the trailer is not level, and check for improper tongue
weight, overloading, worn suspension, or other possible causes.
● The trailer cargo is securely loaded.
● The rear view mirrors conform to all applicable federal, state/provincial or
local regulations. If they do not, install rear view mirrors appropriate for
towing purposes.
No matter which class of tow hitch
applies, for a safe trailer hookup, the
trailer ball setup on must be proper height
for the coupler on the trailer.
