2016 Lexus GS350 ignition

721-2. Theft deterrent system
GS350_200t_GS F_OM_OM30E86U_(U)
Engine immobilizer system
The indicator light flashes after the
engine switch has been turned off to
indicate that the system is operating.
The indicator light stops flashing after
the engine switch has been turned to
ACCESSORY or IGNITION ON
mode to indicate that the system has
been canceled.
■System maintenance
The vehicle has a maintenance-free type engine immobilizer system.
■Conditions that may cause the system to malfunction
●If the grip portion of the key is in contact with a metallic object
●If the key is in close proximity to or touching a key to the security system (key with a
built-in transponder chip) of another vehicle
The vehicle’s keys have built-in transponder chips that prevent the engine
from starting if a key has not been prev iously registered in the vehicle’s on-
board computer.
Never leave the keys inside the vehicle when you leave the vehicle.
This system is designed to help prevent vehicle theft but does not guarantee
absolute security against all vehicle thefts.

• When the engine switch is in IGNITION ON mode, the BSM function is enabled
on of the multi-information display
• When the BSM function is enabled on of the multi-information display, the
engine switch is turned to IGNITION ON mode.
If the system is functioning correctly, the BSM outside rear view mirror indicators will
turn off after a few seconds.
If the BSM outside rear view mirror indica tors do not illuminate or do not turn off,
there may be a malfunction in the system.

■The meters and display illuminate when
The engine switch is in IGNITION ON mode.
■Instrument panel brightness adjustment
The instrument panel brig htness levels when the tail ligh ts are on and off can be adjusted
individually. However, when the surroundings ar e bright (daytime, etc.), turning on the tail
lights will not change the instru ment panel brightness. At this time, any adjustments made
to the instrument panel bright ness levels will be applied to both settings at once.
■Limitation of brightness adjustment
The brightness of the instrume nt panel lights is automatically adjusted based on the light
sensor detecting how bright the surroundings are. However, if the instrument panel
brightness has been manually set to either th e brightest or darkest setting, the automatic
adjustment will not be performed.

■Welcome illumination of the analog speedometer
●When the driver’s door is opened, th e analog speedometer will illuminate.
Then, when the driver’s door is closed, the analog speedometer will illuminate and go
off (pulsate) 3 times.
●In the following situations, the analog speedometer will no t pulsate even though the
driver’s door is opened and closed:
• Within 60 seconds after the analog meter pulsation completes
• Within 60 seconds of turn ing the engine switch off

■Eco driving meter
●The number of blue segments displayed on the eco driving meter decreases/increases
depending on the vehicle acceleration. Use this meter as a guideline when you wish to
drive in an eco-friendly manner that reduces fuel consumption.
However, on a downward grade where the vehicle can accelerate without the acceler-
ator pedal being depressed, the eco driv ing meter may not display the eco-driving
state correctly.
●When the shift lever is moved to P, N or R, the segments will turn gray and the eco driv-
ing meter will not operate.

To help protect the engine, the engine speed is
controlled by changing the starting position of
the tachometer’s red zone depending on the
engine coolant temperature within a range from
3700 rpm to 7300 rpm.
Before driving under extremely high load condi-
tions, make sure to sufficiently warm up the
engine.

■G-force display
●The G-force values may not be zero even when the vehicle is parked, such as when it is
parked on an incline.
●Depending on the vehicle usage conditions,
the brake fluid pressure display may not
reach its maximum reading even though the brake pedal is fully depressed.
●If a battery terminal is disconnected and reconnected, the steering amount display may
be disabled temporarily. After driving the vehi cle for a while, the display will be enabled.
■System check display
After turning the engine switch to IGNITION ON mode, opening image is displayed
while system operation is checked. When the system check is complete, the normal
screen will return.
■Suspension of the settings display
In the following situations, th e settings display using the meter control switches will be
suspended.
●When a warning message appears on the multi-information display
●When the vehicle begins to move
■Tire inflation pressure
●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 infla-
tion pressure after inflation pressure has been adjusted.
●“---” may be displayed if the tire information cannot be determined due to unfavorable
radio wave conditions.
●Tire inflation pressure changes with temperat ure. The displayed values may also be dif-
ferent from the values measured using a tire pressure gauge.
■When disconnecting and reconnecting battery terminals
The drive information will be reset.

■Caution for use while driving
●When operating the multi-information display while driving, pay extra attention to the
safety of the area around the vehicle.
●Do not look continuously at the multi-info rmation display while driving as you may fail
to see pedestrians, objects on the road, etc. ahead of the vehicle.
■Cautions during setting up the display
As the engine needs to be operating during setting up the display, ensure that the vehi-
cle is parked in a place with adequate vent ilation. In a closed area such as a garage,
exhaust gases including harmful carbon mo noxide (CO) may collect and enter the
vehicle. This may lead to death or a serious health hazard.

■Start-up display
When the engine is started, the name of the
vehicle is displayed on the multi-information
display.
While the start-up display is being displaye d, the meter display cannot be changed even
if the drive mode is changed. When the start-up display is finished, the meter display for
the currently selected mode will be displayed.
■Torque distribution display
Torque distribution may not be displayed correctly in some cases, such as when the vehi-
cle passes over road expansion joints.
■G-force display
●The G-force values may not be zero even when the vehicle is parked, such as when it is
parked on an incline.
●The steering amount, accelerator pedal input, and brake fluid pressure displays are dis-
abled until the engine has warmed up (the variable red zone of the tachometer has
retracted to 7300 rpm).
After the engine has warmed up, these displays will be enabled.
●Depending on the vehicle usage conditions, the brake fluid pressure display may not
reach its maximum reading even though the brake pedal is fully depressed.
●If a battery terminal is disconnected and reconnected, the steering amount display may
be disabled temporarily. After driving the vehi cle for a while, the display will be enabled.
■Suspension of the settings display
In the following situations, operation of the settings display will be temporarily sus-
pended.
●When a warning message appears on the multi-information display
●When the vehicle begins to move
■Tire inflation pressure
●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 infla-
tion 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 temperat ure. The displayed values may also be dif-
ferent from the values measured using a tire pressure gauge.
■When disconnecting and reconnecting battery terminals
The following information data will be reset:
●Lap timer: Measured lap times, history
●G-force: Record of the maximum G-forces
■Using the lap timer
If the engine is stopped while a lap is being timed, the lap timer will stop and the lap time
up to that point will be recorded.
