Before driving
Linking driving position memory with door unlock operation (driver
side only)
Memorized driving positions can be recalled when you unlock the
driver’s door using the entry functi on or wireless remote control and
open the driver’s door. Steering wh eel position is recalled when the
power switch is set to the “IG-ON” mode.
■ Setting the link
ed door unlock operation
Set the driving positions into the memor
y system using the “1”, “2”
or “3” buttons on the driver’s side. ( P. 36 )
Turn the power switch to the “OFF” mode, then close the driver’s
door.
Push the “1”, “2” or “3” button on
the driv
er’s side and the or

button on the wireless remote con-
trol at the same time for about 1
second until you hear a beep.
■Recalling the memorized position
Check that the shift lever is set in “P”.
Switch to “IG-ON” mode. Push button “1”, “2” or “3” to
r
ecall the desired position.

ivated within 30 seconds after the co rresponding side door is opened, even if
the power switch is in the “OFF” mode.

Steering wheel
Auto tilt away and auto return
When the power switch is turned
“OFF”, the steering wheel returns
to its stowed position by moving up
and away to enable easier driver
entry and exit.
Switching to “ACC” or “IG-ON”
mode will return the steering wheel
to the original position.
The steering wheel can be adjusted to a comfortable position while the
power switch is in “ACC” or “IG-ON” mode.

CAUTION
■Caution while driving
Do not adjust the steering wheel while driving. 
Doing so may cause the driver to mishandle the vehicle and an accident, resulting in
death or serious injury.

2-1. Driving procedures
CAUTION
■When starting the vehicle
Always keep your foot on the brake pedal while stopped with the hybrid system
running. This prevents the vehicle from creeping.
■When driving the vehicle
●Do not drive if you are unfamiliar with the location of the brake and accelerator
pedals to avoid depressing the wrong pedal. 
Accidentally depressing the accelerator pedal instead of the brake pedal will
result in sudden acceleration that may lead to an accident that could result in
death or serious injury.
●The driver should pay attention to pedest rians when the vehicle is powered only
by the electric motor (traction motor). Because there is no engine noise, the
pedestrians may misjudge the vehicle’s movement.
●Do not drive the vehicle over or stop the vehicle near flammable materials.
●Do not let the vehicle roll backwards while the shift lever is in a driving position, or
roll forward while the shift lever is in “R”. 
Doing so may cause the hybrid system not to operate or lead to poor brake and
steering performance, resulting in an accident or damage to the vehicle.
●If the smell of exhaust is noticed inside the vehicle, open the windows and check
that the trunk is closed. 
Large amounts of exhaust in the vehicle can cause driver drowsiness and eventu-
ally, death. Have the cause of the problem inspected immediately.

2-1. Driving procedures
NOTICE
■While driving the vehicle
Do not use the accelerator pedal or depress accelerator and brake pedals together
to hold the vehicle on a hill.
■When parking the vehicle
Always put the shift lever in “P”. Failure to do so may cause the vehicle to move or
the vehicle may accelerate suddenly if the accelerator pedal is accidentally
depressed.
■Avoiding damage to vehicle parts
●Do not turn the steering wheel fully in either direction and hold it there for a long
time. 
Doing so may damage the power steering motor.
●When driving over bumps in the road, drive as slowly as possible to avoid damag-
ing the wheels, underside of the vehicle, etc.
■If you hear a squealing or scraping no ise (brake pad wear limit indicators)
Have your Lexus dealer check and replac e the brake pads as soon as possible.
The rotor damage can result if the pads are not replaced when needed.
Front brake only: Moderate levels of the brake pad and disc wear allow enhanced
front braking power. As a result, the discs may wear more quickly than conventional
brake discs. Therefore, when replacing the brake pads, Lexus recommends that you
also have the thickness of the discs measured.
It is dangerous to drive the vehicle when the wear limits of the brake pads and/or
that of the brake discs are exceeded.
■If you get a flat tire while driving
A flat or damaged tire may cause the following situations. Hold the steering wheel
firmly and gradually press the brak e pedal to slow down the vehicle.
●It may be difficult to control your vehicle.
●The vehicle will make abnormal sounds.
●The vehicle will behave abnormally.
Replace a flat tire with a new one. ( P. 4 5 9 )

2-4. Using other driving systems
Driving assist systems
To help enhance driving safety and performance, the following systems
operate automatically in response to various driving situations. Be aware,
however, that these systems are supplementary and should not be relied
upon too heavily when operating the vehicle.
■ABS (Anti-lock Brake System)
Restrains the vehicle from slipping when driving on slick road surfaces or
in the event of sudden braking.
■BA (Brake Assist)
Generates an increased level of braking force after the brake pedal is
depressed, when the system detects a panic stop situation.
■VSC (Vehicle Stability Control)
Helps the driver to control skidding wh en swerving suddenly or turning on
slippery road surfaces.
■ TRAC (Traction Control)
Maintains drive power and prevents the rear wheels from spinning when
starting the vehicle or accelerating on slippery roads.
■Hill-start assist control
Helps prevent the vehicle from rolling backwards when starting on an
incline or slippery slope. It operat es for approximately 5 seconds at maxi -
mum.
■ VGRS (Variable Gear Ratio Steering)
Adjusts the wheel turning angle in accordance with the vehicle speed and
steering wheel movement.
■EPS (Electric Power Steering)
Employs an electric motor to reduce the amount of effort needed to turn
the steering wheel.
■Active stabilizer suspension system
Turns at smaller angles to main tain the stable vehicle posture.

2-4. Using other driving systems
To disable TRAC
If the vehicle gets stuck in fresh snow or mud, TRAC may reduce power
from the engine to the wheels. You may need to turn the system off to
enable you to rock the vehicle in order to free it.
Push the button to turn off TRAC.
The slip indicator light should come
on.
Push the button again to turn the
sy
stem back on.
Once you turn the power switch
“
OFF”, TRAC will be activated
automatically.
■Automatic TRAC reactivation
TRAC is reactivated when vehicle speed exceeds 30 mph (50 km/h) even if
“

TRAC OFF” has been turned off.
■Sounds and vibrations caused by the ABS, BA, VSC, TRAC, hill-start assist con-
trol and VGRS systems
●A sound may be heard from the engine compartment when the hybrid system is
started or just after the vehicle begins to move. This sound does not indicate that
a malfunction has occurred in any of these systems.
●Any of the following conditions may occur when the above systems are operat -
ing. None of these indicates that a malfunction has occurred.
• Vibrations may be felt through the vehicle body and steering.
• A motor sound may be heard after the vehicle comes to a stop.
• The brake pedal may pulsate slightly after the ABS is activated.
• The brake pedal may move down slightly af
ter the ABS is activated.
■Hill-start assist control is operational when
●The shift lever is in the “D” or “S” position.
●The brake pedal is not depressed.
