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.

4-1.Before driving
■Starting the engine
 P.125
■Driving
1 With the brake pedal depressed,
shift the shift lever to D. ( P.128)
2 Release the parking brake.
(P.134)
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.128)
■Parking the vehicle
1 With the shift lever in D, depress the
brake pedal.
2 Set the parking brake ( P.134),
and shift the shift lever to P
( P.128).
3 Press the engine switch to stop the
engine.
4 Lock the door, making sure that you
have the electronic key on your
person.
If parking on a hill, block the wheels as
needed.
■Starting off on a steep uphill
1 Make sure that the parking brake is
set and shift the shift lever to D.
2 Gently depress the accelerator
pedal.
3 Release the parking brake.
■When starting off on an uphill
The hill-start assist control will activate.
(  P.192)
■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 wa ter 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
sport mode is selected
■Restraining the engine output (Brake
Override System)
●When the accelerator and brake pedals
are depressed at the same time, the
engine output may be restrained.
●A warning message is displayed on the
multi-information display while the sys-
tem is operating.
Driving the vehicle
The following procedures should be
observed to ensure safe driving:

0_OM_(U)_1810
WARNING
●Do not leave a door or window open if
the curved glass is coated with a met-
allized film such as a silver-colored
one. Reflected sunlight may cause the
glass to act as a lens, causing a fire.
●Always apply the parking brake, shift
the shift lever to P, stop the engine and
lock the vehicle.
Do not leave the vehicle unattended
while the engine is running.
If the vehicle is parked with the shift
lever in P but the parking brake is not
set, the vehicle may start to move, pos-
sibly leading to an accident.
●Do not touch the exhaust pipes while
the engine is running or immediately
after turning the engine off.
Doing so may cause burns.
■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 w ill 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 th e same time while
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.

■When “Access System with Elec. Key
Malfunction See Owner's Manual” is
displayed on the multi-information dis-
play
The system may be malfunctioning. Have
the vehicle inspected by your Lexus dealer
immediately.
■Electronic key battery
 P.265
■Operation of the engine switch
●If the switch is not pressed shortly and
firmly, the engine switch mode may not
change or the engine may not start.
●If attempting to restart the engine imme-
diately after turning the engine switch off,
the engine may not start in some cases.
After turning the engine switch off, please
wait a few seconds before restarting the
engine.
■Customization
If the smart access sy stem with push-button
start has been deactivated in a customized
setting, refer to P.304.
1Stop the vehicle.
2
Set the parking brake ( P.134),
and shift the shift lever to P.
3
Press the engine switch.
4
Release the brake pedal and check
that the display on the meters is off.
Modes can be changed by pressing
the engine switch with brake pedal
released. (The mode changes each
time the switch is pressed.)
WARNING
■When starting the engine
Always start the engine while sitting in
the driver’s seat. Do not depress the
accelerator pedal while starting the
engine under any circumstances.
Doing so may cause an accident result-
ing in death or serious injury.
■Caution while driving
If engine failure occurs while the vehicle
is moving, do not lock or open the doors
until the vehicle reaches a safe and com-
plete stop. Activation of the steering lock
in this circumstance may lead to an acci-
dent, resulting in death or serious injury.
NOTICE
■When starting the engine
●Do not race a cold engine.
●If the engine becomes difficult to start
or stalls frequently, have your vehicle
checked by your Lexus dealer immedi-
ately.
■Symptoms indicating a malfunction
with the engine switch
If the engine switch seems to be operat-
ing somewhat differently than usual, such
as the switch sticking slightly, there may
be a malfunction. Contact your Lexus
dealer immediately.
Stopping the engine
WARNING
■Stopping the engine in an emergency
If you want to stop th e 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.274)
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.
