7-2. Steps to take in an emergency
Fuel pump shut off system
Follow the procedure below to restart the engine after the system is acti-
vated. Turn the engine switch to ACCESSORY mode or turn it off.
Restart the engine.
To minimize the risk of fuel leakage when the engine stalls or when an
airbag inflates upon coll ision, the fuel pump shut off system stops the
supply of fuel to the engine.
NOTICE
■Before starting the engine
Inspect the ground under the vehicle.
If you find that fuel has leaked onto the ground, the fuel system has been damaged
and is in need of repair. Do not restart the engine.

CAUTION
■Maintenance of the tires
Each tire, including the spare (if provided), should be checked monthly when cold
and inflated to the inflation pressure recommended by the vehicle manufacturer on
the vehicle placard or tire inflation pressure label (tire and load information label).
(If your vehicle has tires of a different size than the size indicated on the vehicle
placard or tire inflation pressure label [tire and load information label], you should
determine the proper tire inflation pressure for those tires.)
As an added safety feature, your vehicle has been equipped with a tire pressure
monitoring system (TPMS-tire pressure warning system) that illuminates a low tire
pressure telltale (tire pressure warning light) when one or more of your tires is sig-
nificantly under-inflated. Accordingly, when the low tire pressure telltale (tire pres-
sure warning light) illuminates, you should stop and check your tires as soon as
possible, and inflate them to the proper pressure. Driving on a significantly under-
inflated tire causes the tire to overheat and can lead to tire failure. Under-inflation
also reduces fuel efficiency and tire tread life, and may affect the vehicle’s handling
and stopping ability.
Please note that the TPMS (tire pressure warning system) is not a substitute for
proper tire maintenance, and it is the driver’s responsibility to maintain correct tire
pressure, even if under-inflation has not reached the level to trigger illumination of
the TPMS low tire pressure telltale (tire pressure warning light).
Your vehicle has also been equipped with a TPMS (tire pressure warning system)
malfunction indicator to indicate when the system is not operating properly. The
TPMS (tire pressure warning system) malfunction indicator is combined with the
low tire pressure telltale (tire pressure warning light). When the system detects a
malfunction, the telltale will flash for approximately one minute and then remain
continuously illuminated. This sequence will continue upon subsequent vehicle
start-ups as long as the malfunction exists. When the malfunction indicator is illumi-
nated, the system may not be able to detect or signal low tire pressure as intended.

Warning messageDetailsCorrection procedure
(If equipped)
Indicates that the tire
inflation pressure is lowCheck the tire inflation
pressure, and adjust to
the appropriate level.
(If equipped)
Indicates a malfunction in
the tire pressure warning
system
Stop the vehicle in a safe
place and turn the engine
switch off then on again.If the tire pressure
warning indicator
flashes for 1 minute
then illuminates, there
is a malfunction in the
system. Have the vehi-
cle inspected at your
Lexus dealer.
(If equipped)
Indicates that the tire
position information can-
not be recognized
Drive for a short while
and check if the display
updates.If the radio wave condi-
tions improve, the dis-
play may return to
normal. If the tire pres-
sure is still not dis-
played after driving for
several minutes, stop
the vehicle in a safe
place, turn the engine
switch off then on
again, and start driving.
If the tire pressure is still
not displayed even
after repeating this sev-
eral times, have the
vehicle inspected at
your Lexus dealer.

Release the brake pedal and press the engine switch in step above.
The engine does not start and modes will be changed each time the switch is
pressed.( →P. 1 74 )
■When the electronic key does not work properly
●Make sure that the smart access system with push-button start has not been deac-
tivated in the customization setting. If it is off, turn the function on.
(Customizable features: →P. 7 9 3 )
●Check if battery-saving mode is set. If it is set, cancel the function. ( →P. 1 0 9 )

GS350_OM_OM30D41U_(U)The coolant level is satisfactory if it is between the “FULL” and “LOW”
lines on the reservoir.
Reservoir
“FULL”
“LOW”
Coolant inlet cap
Add coolant if necessary.
Water can be used in an emergency if
coolant is unavailable.
Start the engine and turn the air conditioning system on to check that
the radiator cooling fans operate and to check for coolant leaks from
the radiator or hoses.
The fans operate when the air conditioning system is turned on immediately after
a cold start. Confirm that the fans are operating by checking the fan sound and air
flow. If it is difficult to check these, turn the air conditioning system on and off
repeatedly. (The fans may not operate in freezing temperatures.)
If the fans are not operating:
Stop the engine immediately an d contact your Lexus dealer.
If the fans are operating:
Have the vehicle inspected at the nearest Lexus dealer.

Vehicle specifications
■Vehicle customization
●When the speed linked door locking function and shift position linked door locking
function are both on, the door lock operates as follows.
• When shifting the shift lever to any position other than P, all the doors will belocked.
• If the vehicle is started with all the doors locked, the speed linked door locking function would not operate.
• If the vehicle is started with any door unlocked, the speed linked door locking function will operate.
●When the smart access system with push-button start is off, the selecting door to
unlock cannot be customized.
●When the doors remain closed after unlocking the doors and the automatic door
lock function (time elapsed before the automatic door lock function is activated if a
door is not opened after being unlocked) activates, the signals will be generated in
accordance with the operation signal (buzzers) and the operation signal (emer-
gency flashers) settings.
■When customizing using the Remote Touch
Stop the vehicle in a safe place, apply the parking brake, and shift the shift lever to P.
Also, to prevent battery discharge, leave the engine running while customizing the
features.
CAUTION
■During customization
As the engine needs to be running during customization, 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.
NOTICE
■During customization
To prevent battery discharge, ensure that the engine is running while customizing
features.
