When trouble arises
7-1. Essential information
If your vehicle has to be stopped in an emergency
Steadily step on the brake pedal with both feet and firmly depress it.
Do not pump the brake pedal repeatedly as this will increase the effort required to
slow the vehicle.
Shift the shift lever to N.
If the shift lever is shifted to N
After slowing down, stop the vehicle in a safe place by the road.
Stop the engine .
If the shift lever cannot be shifted to N
Keep depressing the brake pedal wi th both feet to reduce vehicle
speed as much as possible.
Gasoline vehicles: To stop the
engine, press and hold the
“START STOP ENGINE” switch
for 2 consecutive seconds or
more, or press it briefly 3 times or
more in succession.
Hybrid vehicles: To stop the
hybrid system, press and hold the
“POWER” switch for 2 consecu-
tive seconds or more, or press it
briefly 3 times or more in succes-
sion.
Stop the vehicle in a safe place by the road.
Only in an emergency, such as if it becomes impossible to stop the vehi-
cle in the normal way, stop the vehicle using the following procedure:

When trouble arises
If your Lexus is transported by a flat
bed truck, it should be tied down at
the locations shown in the illustra-
tion.
If you use chains or cables to tie
down your vehicle, the angles
shaded in black must be 45 .
Do not overly tighten the tie downs
or the vehicle may be damaged.
■Before emergency towing Release the parking brake.
Shift the shift lever to N.
Gasoline vehicles: Turn the “START STOP ENGINE” switch to ACCESSORY
(engine off) or IGNITION ON (engine running) mode.
Hybrid vehicles: Turn the “POWER” swit ch to ACCESSORY (hybrid system off)
or ON (hybrid system operating) mode.

7-2. Steps to take in an emergency
Fuel pump shut off system (gasoline vehicles)
Follow the procedure below to restart the engine after the system is acti-
vated.
Turn the “START STOP 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 collision, 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 th e ground, the fuel system has been damaged
and is in need of repair. Do not restart the engine.

When trouble arises
*1: Open door warning buzzer: P. 7 74
*2: Driver’s seat belt buzzer:
The driver’s seat belt buzzer sounds to al ert the driver that his or her seat belt is
not fastened. Once the “START STOP EN GINE” <“POWER”> switch is turned to
IGNITION ON mode, the buzzer sounds for 6 seconds. If the vehicle
reaches a speed of 12 mph (20 km/h), the buzzer sounds once. If the seat belt is
still unfastened after 30 seconds, the buzz er will sound intermittently for 10 sec-
onds. Then, if the seat belt is still unfast ened, the buzzer will sound in a different
tone for 20 more seconds.
Front passenger’s seat belt buzzer:
The front passenger’s seat belt buzzer soun ds to alert the front passenger that his
or her seat belt is not fastened. The buzzer sounds once if the vehicle reaches a
speed of 12 mph (20 km/h). If the seat be lt is still unfastened after 30 seconds,
the buzzer will sound intermittently for 10 seconds. Then, if the seat belt is still
unfastened, the buzzer will sound in a different tone for 20 more seconds.
Tire pressure warning light
When the light comes on:
Low tire inflation pressure such
as
• Natural causes ( P. 765)
• Flat tire ( P. 7 9 2 )
Adjust the tire inflation pressure
(including the full-size spare
tire) to the specified level.
The light will turn off after a
few minutes. In case the light
does not turn off even if the
tire inflation pressure is
adjusted, have the system
checked by your Lexus
dealer.
When the light comes on after
blinking for 1 minute:
Malfunction in the tire pressure
warning system
Have the system checked by
your Lexus dealer.

When trouble arises
■The tire pressure warning light may come on due to natural causes
The tire pressure warning light may come on due to natural causes such as natural
air leaks and tire inflation pressure changes caused by temperature. In this case,
adjusting the tire inflation pressure will turn off the warning light (after a few minutes).
■When a tire is replaced with a spare tire
Vehicles with a compact spare tire: The compact spare tire is not equipped with a tire
pressure warning valve and transmitter. If a tire goes flat, the tire pressure warning
light will not turn off even though the flat tire has been replaced with the spare tire.
Vehicles with a full-size spare tire: The spare tire is also equipped with a tire pressure
warning valve and transmitter. The tire pressure warning light will turn on if the tire
inflation pressure of the spare tire is low. If a tire goes flat, the tire pressure warning
light will not turn off even though the flat tire has been replaced with the spare tire.
■Conditions that the tire pressure warning system may not function properly
P. 7 0 7
■If the tire pressure warning light freque ntly comes on after blinking for 1 minute
If the tire pressure warning light frequently comes on after blinking for 1 minute when
the “START STOP ENGINE” <“POWER”> switch is turned to IGNITION ON
mode, have it checked by your Lexus dealer.
■Electric power steering system warning light (warning buzzer)
When the 12-volt battery charge becomes insufficient or the voltage temporarily
drops, the electric power steering system warning light may come on and the warn-
ing buzzer may sound.
■Warning buzzer
In some cases, the buzzer may not be he ard because of noisy place or an audio
sound.

When trouble arises
CAUTION
■Maintenance of the tires
Each tire, including the spare (if provided), should be checked monthly when cold
and inflated to the inflation pressure re commended by the vehicle manufacturer on
the vehicle placard or tire inflation pressu re 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 [t ire 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 wa rning 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 re ached 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 th e 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.
