1763-4. Adjusting the steering wheel and mirrors
GS350/250_EE (OM30C36E)
Mirror angle can be adjusted when
The engine switch is in ACCESSORY or IGNITION ON mode.
Linked mirror function when reversing
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 func-
tion, select neither “L” nor “R”.
If the mirror angle adjustment switch is operated while the linked mirror
function is in operation, the angle and position of the mirrors can be remem-
bered, and the mirrors will operate at the angle adjusted to the last time the
linked mirror function was operated.
However, because the mirrors move based on the angle they are in when the
linked mirror function is not operating, the mirror angle when the linked
mirror function is operating will also be changed if the mirrors are adjusted
while the function is not operating.
Rain clearing mirrors (if equipped)
When water droplets collects on the mirror surface, for example when it
rains, the rain clearing (hydrophilic) effect of the mirrors causes the droplets
to be spread out into a film making the rear view clearer. In the following
cases, the rain clearing effect will be reduced temporarily, but will return
after 1 or 2 days’ exposure to direct sunlight.
After wiping dirt off the mirrors
When the mirrors fog up
After waxing your vehicle in an automatic car wash
After your vehicle has been parked for a long period in underground park-
ing lots etc. where there is no direct sunlight
When the mirrors are fogged up
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. 430)
Automatic adjustment of the mirror angle
A desired mirror face angle can be entered to memory and recalled automati-
cally by the driving position memory. (P. 162)

Operation of each component
GS350/250_EE (OM30C36E)
The power windows can be operated when
The engine switch is in IGNITION ON mode.
Operating the power windows after turning the engine off
The power windows can be operated for approximately 45 seconds even after
the engine switch is turned to ACCESSORY mode or turned off. They can-
not, however, be operated once either front door is opened.
Jam protection function
If an object becomes caught between the window and the window frame,
window travel is stopped and the window is opened slightly.
When the power window does not close normally
If the jam protection function is operating abnormally and a window cannot
be closed, perform the following operations using the power window switch
on the relevant door.
After stopping the vehicle, the window can be closed by holding the power
window switch in the one-touch closing position while the engine switch is
turned to IGNITION ON mode.
If the window still cannot be closed even by carrying out the operation as
explained above, initialize the function by performing the following proce-
dure.
Hold the power window switch in the one-touch closing position. Con-
tinue holding the switch for a further 6 seconds after the window has
closed.
Hold the power window switch in the one-touch opening position. Con-
tinue holding the switch for a further 2 seconds after the window has
opened completely.
Hold the power window switch in the one-touch closing position once
again. Continue holding the switch for a further 2 seconds after the win-
dow has closed.
If you release the switch while the window is moving, start again from the
beginning.
If the window continues to close but then re-open slightly even after per-
forming the above procedure correctly, have the vehicle inspected by any
authorized Lexus dealer or repairer, or another duly qualified and equipped
professional.
