Display contents

1102. Instrument cluster
GS350/250_EE (OM30C36E)
Tire inflation pressure (if equipped)
It may take a few minutes to display the tire inflation pressure after the
engine switch is turned to IGNITION ON mode. It may also take a few
minutes to display the tire inflation pressure after inflation pressure has
been adjusted.
“---” may be displayed if the tire position information cannot be determined
due to unfavorable radio wave conditions.
Tire inflation pressure changes with temperature. The displayed values may
also be different from the values measured using a tire pressure gauge.
Liquid crystal display
Small spots or light spots may appear on the display. This phenomenon is
characteristic of liquid crystal displays, and there is no problem continuing to
use the display.
Customization
Setting of available languages can be changed. (Customizable features P.
857)
CAUTION
The information display at low temperatures
Allow the interior of the vehicle to warm up before using the liquid crystal
information display. At extremely low temperatures, the information dis-
play monitor may respond slowly, and display changes may be delayed.
For example, there is a lag between the driver’s shifting and the new gear
number appearing on the display. This lag could cause the driver to down-
shift again, causing rapid and excessive engine braking and possibly an
accident resulting in death or injury.
Cautions during setting up the display
As the engine needs to be running during setting up the display, ensure that
the vehicle is parked in a place with adequate ventilation. In a closed area
such as a garage, exhaust gases including harmful carbon monoxide (CO)
may collect and enter the vehicle. This may lead to death or a serious health
hazard.

1203-1. Key information
GS350/250_EE (OM30C36E)
Card key (if equipped)
The card key is not waterproof.
The mechanical key that is stored inside the card key should be used only if
a problem arises, such as when the card key does not operate properly.
If it is difficult to take out the mechanical key, push down the lock release
button using a pen tip etc. If it is still difficult to pull it out, use a coin etc.
When required to leave the vehicle’s key with a parking attendant
Turn the trunk opener main switch off, lock the glove box and armrest door
as circumstances demand. (P. 151, 616, 639)
Remove the mechanical key for your own use and provide the attendant with
the electronic key only.
If you lose your mechanical keys
New genuine mechanical keys can be made by any authorized Lexus dealer
or repairer, or another duly qualified and equipped professional using the
other mechanical key and the key number stamped on your key number plate.
Keep the plate in a safe place such as your wallet, not in the vehicle.
To store the mechanical key in the card
key, insert it while pressing the lock
release button.
If the battery cover is not installed and
the battery falls out or if the battery was
removed because the key got wet, rein-
stall the battery with the positive termi-
nal facing the Lexus emblem.

1533-2. Opening, closing and locking the doors and trunk

Operation of each component
GS350/250_EE (OM30C36E)
Overload protection function (vehicles with power trunk lid)
The trunk lid will not operate when excessive load is present on the top of the
trunk lid.
Fall-down protection function (vehicles with power trunk lid)
While the trunk lid is opening automatically, applying excessive force to it
will stop the opening operation to prevent the trunk lid from rapidly falling
down.
Jam protection function (vehicles with power trunk lid)
While the trunk lid is closing automatically, the trunk lid will stop closing
and open if something gets caught.
Using the mechanical key
The trunk can be also opened using the mechanical key. (P. 822)
When leaving a key to the vehicle with a parking attendant
P. 1 2 0
CAUTION
Observe the following precautions.
Failure to do so may result in death or serious injury.
Before driving
Make sure that the trunk lid is fully closed. If the trunk lid is not fully
closed, it may open unexpectedly while driving and hit near-by objects or
luggage in the trunk may be thrown out, causing an accident.
Do not allow children to enter the trunk.
If a child is accidentally locked in the trunk, they could overheat or suffo-
cate.
Do not allow a child to open or close the trunk lid.
Doing so may cause the trunk lid to open unexpectedly, or cause the
child’s hands, head, or neck to be caught by the closing trunk lid.
Important points while driving
Never let anyone sit in the trunk. In the event of sudden braking or a colli-
sion, they are susceptible to death or serious injury.

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)

1884-1. Before driving
GS350/250_EE (OM30C36E)Make sure that the parking brake is set and shift the shift lever to
D.
Gently depress the accelerator pedal.
Release the parking brake.
When starting off on a uphill
The hill-start assist control is available. (P. 339)
Driving in the rain
Drive carefully when it is raining, because visibility will be reduced, the
windows 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 water between the tires and the road sur-
face, preventing the steering and brakes from operating properly.
Engine speed while driving
In the following conditions, the engine speed may become high while driv-
ing. This is due to automatic up-shifting control or down-shifting implemen-
tation to meet driving conditions. It does not indicate sudden acceleration.
The vehicle is judged to be driving uphill or downhill
When the accelerator pedal is released
When sport mode is selected (P. 3 2 6 )
