of death or serious injury in the event of an accident.
Adjustments should not be made while drivin g as the seat may unexpectedly move and

Operation of each component
GS350_300_GS F_OM_OM30G34U_(U)
When either “L” or “R” of the mirror 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 reversing
With the shift lever in R, adjust the mirror angle at a desired position. The
adjusted angle will be memorized and the mirror will automatically tilt to the
memorized angle whenever the shift leve r is shifted to R from next time.
The memorized downward tilt position of th e mirror is linked to the normal position
(angle adjusted with the shif t lever in other than R). Ther efore, if the normal posi-
tion is changed after adjustment, the tilt position will also change.
When the normal position is chang ed, readjust the angle in reversing.
■Mirror angle can be adjusted when
The engine switch is in ACCESSORY or IGNITION ON mode.
■When the mirrors are fogged up
The outside rear view mirrors can be cleare d using the mirror defoggers. Turn on the
rear window defogger to turn on the outside rear view mirror defoggers. ( →P. 314)
■Automatic adjustment of the mirror angle
A desired mirror face angle can be entered to memory and recalled automatically by the
driving position memory. ( →P. 160)
■Auto anti-glare function
When the anti-glare inside re ar 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 reflected light. ( →P. 169)
■Using automatic mode in cold weather (if equipped)
When automatic mode is used in cold weather, the door mirror could freeze up and
automatic stowing and return may not be possible. In this event, remove any ice and snow
from the door mirror, then either operate th e mirror using manual mode or move the mir-
ror by hand.
