switch is turned to IGNITION ON
mode to indicate that a system check is
being performed. They will turn off after
the engine is started, or after a few sec-
onds. There may be a malfunction in a
system if the lights do not come on, or
turn off. Have the vehicle inspected by
your Lexus dealer.

The indicators inform the driver of the
operating state of the vehicle’s various
systems.
WARNING
■If a safety system warning light does
not come on
Should a safety system light such as the
ABS and SRS warning light not come on
when you start the engine, this could
mean that these systems are not available
to help protect you in an accident, which
could result in death or serious injury.
Have the vehicle inspected by your
Lexus dealer immediately if this occurs.

1204-1. Before driving
4-1.Before driving
■Starting the engine
 P.130
■Driving
1 With the brake pedal depressed,
shift the shift lever to D. ( P.134)
2 If the parking brake is in manual
mode, release the parking brake.
( P.139)
3 Gradually release the brake pedal
and gently depress the accelerator
pedal to accelerate the vehicle.
■Stopping
1 With the shift lever in D, depress the
brake pedal.
2 If necessary, set the parking brake.
If the vehicle is to be stopped for an
extended period of time, shift the shift lever
to P or N. ( P.134)
■Parking the vehicle
1 With the shift lever in D, depress the
brake pedal.
2 Set the parking brake ( P.139),
and shift the shift lever to P
(  P.134).
Check that the parking brake indicator is
illuminated.
If parking on a hill, block the wheels as
needed.
3 Press the engine switch to stop the
engine. 4
Lock the door, making sure that you
have the electronic key on your
person.
■Starting off on a steep uphill
1 With the brake pedal depressed,
shift the shift lever to D. ( P.135)
2 Pull the parking brake switch to set
the parking brake manually.
( P.139)
3 Release the brake pedal and gently
depress the accelerator pedal to
accelerate the vehicle.
4 Press the parking brake switch to
release the parking brake manually.
■When starting off on an uphill
The hill-start assist control will activate.
( P.229)
■Driving in the rain
●Drive carefully when it is raining, because
visibility will be re duced, the windows
may become fogged-u p, 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 surface, preventing the
steering and brakes from operating prop-
erly.
■Engine speed while driving
In the following conditions, the engine
speed may become high while driving. This
is due to automatic up-shifting control or
down-shifting implementation to meet driv-
ing conditions. It does not indicate sudden
acceleration.
●The vehicle is judged to be driving uphill
or downhill
●When the accelerato r pedal is released
●When the brake pedal is depressed while
Driving the vehicle
The following procedures should be
observed to ensure safe driving:
Driving procedure

1244-1. Before driving
WARNING
■When taking a nap in the vehicle
Always turn the engine off. Otherwise, if
you accidentally move the shift lever or
depress the accelerator pedal, this could
cause an accident or fire due to engine
overheating. Additionally, if the vehicle is
parked in a poorly ventilated area,
exhaust gases may collect and enter the
vehicle, leading to death or a serious
health hazard.
■When braking
●When the brakes are wet, drive more
cautiously.
Braking distance increases when the
brakes are wet, and this may cause one
side of the vehicle to brake differently
than the other side. Also, the parking
brake may not securely hold the vehi-
cle.
●If the brake booster device does not
operate, do not follow other vehicles
closely and avoid hills or sharp turns
that require braking.
In this case, braking is still possible, but
the brake pedal should be depressed
more firmly than usual. Also, the brak-
ing distance will increase. Have your
brakes fixed immediately.
●Do not pump the brake pedal if the
engine stalls.
Each push on the brake pedal uses up
the reserve for the power-assisted
brakes.
●The brake system consists of 2 individ-
ual hydraulic systems; if one of the sys-
tems fails, the other will still operate. In
this case, the brake pedal should be
depressed more firmly than usual and
the braking distance will increase.
Have your brakes fixed immediately.
■If the vehicle becomes stuck
Do not spin the wheels excessively when
any of the tires is up in the air, or the vehi-
cle is stuck in sand, mud, etc. This may
damage the driveline components or
propel the vehicle forward or backward,
causing an accident.
NOTICE
■When driving the vehicle
●Do not depress the accelerator and
brake pedals at the same time during
driving, as this may restrain the engine
output.
●Do not use the accelerator pedal or
depress the accelerator and brake
pedals at the same time to hold the
vehicle on a hill.
■When parking the vehicle
Always set the parking brake and shift
the shift lever to P. Failure to do so may
cause the vehicle to move or the vehicle
may accelerate suddenly if the accelera-
tor pedal is accidentally depressed.
■Avoiding damage to vehicle parts
●Do not turn the steering wheel fully in
either direction and hold it there for an
extended period of time.
Doing so may damage the power
steering motor.
●When driving over bumps in the road,
drive as slowly as possible to avoid
damaging the wheels, underside of the
vehicle, etc.
●IS300: Make sure to idle the engine
immediately after high-load driving.
Stop the engine only after the
turbocharger has cooled down.
Failure to do so may cause damage to
the turbocharger.

1324-2. Driving procedures
Modes can be changed by pressing
the engine switch with brake pedal released. (The mode changes each
time the switch is pressed.)

Off
*
The emergency flashers can be used.
The multi-information display will not be
displayed.
2ACCESSORY mode
Some electrical components such as the
audio system can be used.
“ACCESSORY” will be displayed on the
meters.
3IGNITION ON mode
All electrical components can be used.
“IGNITION ON” will be displayed on the
meters.
*: If the shift lever is in a position other than
P when turning off the engine, the
engine switch will be turned to ACCES-
SORY mode, not to off.
■Auto power off function
If the vehicle is left in ACCESSORY mode
for more than 20 minutes or IGNITION

WARNING
■Stopping the engine in an emergency
If you want to stop the engine in an emer-
gency while driving the vehicle, press
and hold the engine switch for more than
2 seconds, or press it briefly 3 times or
more in succession. ( P.320)
However, do not touch the engine switch
while driving except in an emergency.
Turning the engine off while driving will
not cause loss of steering or braking con-
trol, but the power assist to these systems
will be lost. This will make it more difficult
to steer and brake, so you should pull
over and stop the vehicle as soon as it is
safe to do so.
■When parking
Exhaust gases include harmful carbon
monoxide (CO), which is colorless and
odorless. Observe the following precau-
tions.
Failure to do so may cause exhaust gases
to enter the vehicle and may lead to an
accident caused by light-headedness, or
may lead to death or a serious health
hazard.
●If the vehicle is in a poorly ventilated
area or a closed area, such as a
garage, stop the engine.
●Do not leave the vehicle with the
engine running for a long time. If such
a situation cannot be avoided, park the
vehicle in an open space and ensure
that exhaust fumes do not enter the
vehicle interior.
●Do not leave the engine running in an
area with snow build-up, or where it is
snowing. If snowbanks build up around
the vehicle while the engine is running,
exhaust gases may collect and enter
the vehicle.

PKSA (Parking Support
Alert)
The Parking Support Alert system
consists of the following functions
that operate when driving at a low
speed or backing up, such as when
parking. When the system deter-
mines that the possibility of a colli-
sion with a detected object, such as
a wall is high, a warning operates to
urge the driver to take evasive
action.
