■Mirror angle can be adjusted when
The engine switch is in ACCESSORY or
IGNITION ON mode.
■Defogging the mirrors
The outside rear view mirrors can be
cleared using the mirror defoggers. Turn on
the rear window defogger to turn on the
outside rear view mirror defoggers.
(  P.253)
■Automatic adjustment of the mirror
angle (if equipped)
A desired mirror face angle can be entered
to memory and recalled automatically by
the driving position memory. ( P.108)
■Auto anti-glare function (if equipped)
When the anti-glare inside rear view mirror
is set to automatic mode, the outside rear
view mirrors will activate in conjunction with
the anti-glare inside rear view mirror to
reduce reflec ted light. (P.114)
■Linked mirror function when reversing
(if equipped)
When either “L” or “R” of the mirror select
switch is selected, the outside rear view mir-
rors will automatically angle downwards
when the vehicle is re versing in order to
give a better view of the ground.
Outside rear view mirrors
The rear view mirror’s position can
be adjusted to enable sufficient
confirmation of the rear view.
WARNING
■Important points while driving
Observe the following precautions while
driving.
Failure to do so may result in loss of con-
trol of the vehicle and cause an accident,
resulting in death or serious injury.
●Do not adjust the mirrors while driving.
●Do not drive with the mirrors folded.
●Both the driver and passenger side
mirrors must be extended and prop-
erly adjusted before driving.

3
Before driving
To disable this function, select neither “L”
nor “R”.
To set the mirror angle used when the vehi-
cle is reversing, adjust the mirror angle at a
desired position with the shift position in R.
The adjusted angle will be memorized and
the mirror will automatically tilt to the mem-
orized angle whenever the shift lever is
shifted to R from next time.
The memorized downward tilt position of
the mirror is linked to the normal position
(angle adjusted with th e shift lever in other
than R). Therefore, if the normal position is
changed after adjustment, the tilt position
will also change.
When the normal position is changed, read-
just the angle in reversing.
Push the mirror back in the direction of
the vehicle’s rear.
WARNING
■When the mirror defoggers are oper-
ating
Do not touch the rear view mirror sur-
faces, as they can become very hot and
burn you.

may become fogged-up, and the road
will be slippery.
●Drive carefully when it starts to rain,
because the road surface will be espe-
cially slippery.
●Refrain from high speeds when driving on
an expressway in the rain, because there
may be a layer of wa ter between the tires
and the road surface, preventing the
steering and brakes from operating prop-
erly.
■Engine speed while driving
In the following conditions, the engine
speed may become high while driving. This
is due to automatic up-shifting control or
down-shifting implementation to meet driv-
ing conditions. It does not indicate sudden
acceleration.
●The vehicle is judged to be driving uphill
or downhill
●When the accelerato r pedal is released
●When the brake pedal is depressed while

Driving procedure

1524-3. Operating the lights and wipers
●The high beams may be turned off if a
vehicle ahead that is using fog lights with-
out its headlights turned on is detected.
●House lights, street lights, traffic signals,
and illuminated billboards or signs and
other reflective objects may cause the
high beams to change to the low beams,
or the low beams to remain on.
●The following factors may affect the
amount of time taken for the high beams
to turn on or off:
• The brightness of the headlights, fog lights, and tail lights of vehicles ahead
• The movement and direction of vehicles ahead
• When a vehicle ahead only has opera-
tional lights on one side
• When a vehicle ahead is a two-wheeled vehicle
• The condition of the road (gradient, curve, condition of th e road surface, etc.)
• The number of passengers and amount of
luggage in the vehicle
●The high beams may turn on or off unex-
pectedly.
●Bicycles or similar vehicles may not be
detected.
●In the following situations the system may
not be able to correctly detect the sur-
rounding brightness le vel. This may cause
the low beams to remain on or the high
beams to flash or dazzle pedestrians or
vehicles ahead. In such a case, it is neces-
sary to manually switch between the high
and low beams.
• When driving in inclement weather
(heavy rain, snow, fog, sandstorms, etc.)
• When the windshield is obscured by fog, mist, ice, dirt, etc.
• When the windshield is cracked or dam-
aged
• When the camera sensor is deformed or dirty
• When the temperature of the camera sensor is extremely high
• When the surrounding brightness level is equal to that of head lights, tail lights or
fog lights
• When headlights or tail lights of vehicles ahead are turned off, dirty, changing
color, or not aimed properly
• When the vehicle is hit by water, snow, dust, etc. from a preceding vehicle
• When driving through an area of inter- mittently changing brightness and dark-
ness
• When frequently and repeatedly driving ascending/descending roads, or roads
with rough, bumpy or uneven surfaces
(such as stone-paved roads, gravel roads,
etc.)
• When frequently and repeatedly taking curves or driving on a winding road
• When there is a highly reflective object
ahead of the vehicle, such as a sign or
mirror
• When the back of a preceding vehicle is
highly reflective, such as a container on a
truck
• When the vehicle’s headlights are dam-
aged or dirty, or are not aimed properly
• When the vehicle is listing or titling due to a flat tire, a trailer being towed, etc.
• When the headlights are changed between the high beams and low beams
repeatedly in an abnormal manner
• When the driver believes that the high beams may be flashing or dazzling
pedestrians or other drivers
■Temporarily lowering sensor sensitivity
The sensitivity of the sensor can be tempo-
rarily lowered.
1 Turn the engine switch off while the fol-
lowing conditions are met.
●The headlight switch is in or .
●The headlight switch lever is in the origi-
nal position.
●Automatic High Beam switch is on.
2 Turn the engine switch to IGNITION
ON mode.
