ide (CO) may collect and enter
the vehicle. This may lead to
death or a seri ous health hazard.

1573-4. Adjusting the steering wheel and mirrors
Owners Manual_USA_M0C052_en

Before driving
From inside
1 Folds the mirrors
2 Unfolds the mirrors
Putting the switch in the neutral
position sets the mirrors to auto-
matic mode. Automatic mode
allows the folding or unfolding of
the mirrors to be linked to lock-
ing/unlocking of the doors.
■Using automatic mode in cold
weather
When automatic mode is used in
cold weather, the door mirror could
freeze up and aut omatic stowing
and return may not be possible. In
this case, remove any ice and snow
from the door mirror, then either
operate the mirror using manual
mode or move the mirror by hand.
■Customization
Some functions can be customized.
(  P.561)
The mirror can be deployed to
the outer side in order to
improve rear visibility when tow-
ing a wide trailer.
Press the switch and extend the
mirror.
Press the switch again to return
the mirror to the original posi-
tion.
■Using the extending mirrors in
cold weather
The door mirror extending & retract-
ing functions could freeze up and
extending or retracting may not be
possible. In this c ase, remove any
ice and snow from the mirror, then
either operate the mirror by pressing
the extend or retract switch or move
the mirror by hand.
WARNING
■When a mirror is moving
To avoid personal injury and mir-
ror malfunction, be careful not to
get your hand caught by the mov-
ing mirror.
Extending the mirrors (if
equipped)

1583-4. Adjusting the steering wheel and mirrors
Owners Manual_USA_M0C052_en
■Recommended mirror angle
when towing a trailer (vehicles
with extending mirrors)
1 Power adjust the upper part of
the mirror until an appropriate
view is obtained. It is recom-
mended that the outer 2/3 of the
upper mirror be f illed with images
other than the vehicle and trailer.
2 Manually adjust the lower part of
the mirror until an appropriate
view of the towed object is
obtained. It is recommended that
the outer 2/3 of the lower mirror
be filled with images other than
the trailer.
When either “L” or “R” of the mir-
ror select switch is selected, the
outside rear view mirrors will
automatically angle downwards
when the vehicle is reversing in
order to give a better view of the
ground. To disable this function, select
neither “L” nor “R”.
■Adjusting the mirror angle
when the vehicle is revers-
ing
With the shift lever in R, adjust
the mirror angle at a desired
position.
The adjusted angle will be mem-
orized and the mirror will auto-
matically tilt to the memorized
angle whenever the shift lever is
shifted to R from next time.
The memorized downward tilt posi-
tion of the mirror is linked to the
normal position (angle adjusted
with the shift posit ion 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, readjust the angle in
reversing.
Improves reverse operation for
trailer parking by turning on the
outer mirror lights at night.
These lights can be used as
work lights.
When the shift lever is in P or R,
press the switch.
