By keeping the indicator needle within Eco area, more Eco-friendly driv-
ing can be achieved.
Charge area indicates regeneration* status. Regenerated energy will be
used to charge the battery.
*:When used in this manual, “regeneration” refers to the conversion of
energy created by the movement of the vehicle into electrical energy.

Driving assist systems
To help enhance driving safety and performance, the following sys-
tems 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)
Helps to prevent wheel lock when the brakes are applied suddenly,
or if the brakes are applied while driving on a slippery road surface
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 when swerving suddenly or
turning on slippery road surfaces
TRC (Traction Control)
Helps to maintain drive power and prevent the drive wheels from
spinning when starting the vehicle or accelerating on slippery roads
EPS (Electric Power Steering)
Employs an electric motor to reduce the amount of effort needed to
turn the steering wheel

VSC + (Vehicle Stability Control +)
Provides cooperative control of the ABS, TRC, VSC and EPS.
Helps to maintain directional stability when swerving on slippery
road surfaces by controlling steering performance.
Hill-start assist control
P. 296
PCS (Pre-Crash Safety system) (if equipped)
P. 299
Emergency brake signal

When the VSC/TRC systems are operating
If the vehicle is in danger of
slipping or if any of the drive
wheels spins, the slip indicator
light flashes to indicate that the
VSC/TRC systems are operat-
ing.
Sounds and vibrations caused by the ABS, brake assist, VSC and TRC
A sound may be heard from the engine compartment when the hybrid
system is started, just after the vehicle begins to move, if the brake pedal
is depressed forcefully or repeatedly, or 1-2 minutes after the hybrid sys-
tem is stopped. 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
operating. 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 after the ABS is activated.
EPS operation sound
When the steering wheel is operated, a motor sound (whirring sound) may
be heard. This does not indicate a malfunction.
Reduced effectiveness of the EPS system
The effectiveness of the EPS system is reduced to prevent the system from
overheating when there is frequent steering input over an extended period of
time. The steering wheel may feel heavy as a result. Should this occur,
refrain from excessive steering input or stop the vehicle and turn the hybrid
system off. The EPS system should return to normal within 10 minutes.

Hill-start assist control
Hill-start assist control operating conditions
The system operates in the following situations:
• The shift position is in a position other than P.
• The parking brake is not applied.
• The accelerator pedal is not depressed.
Hill-start assist control cannot be operated while the slip indicator light
is illuminated.
Hill-start assist control helps to prevent the vehicle from rolling back-
wards when starting on an incline or slippery slope.
To engage hill-start assist
control, further depress the
brake pedal when the vehicle
is stopped completely.
A buzzer will sound once to
indicate the system is acti-
vated. The slip indicator will
also start flashing.

Hill-start assist control
While hill-start assist control is operating, the brakes remain automati-
cally applied after the driver releases the brake pedal. The stop lights and
the high mounted stoplight turn on.
Hill-start assist control operates for about 2 seconds after the brake pedal
is released.
If the slip indicator does not flash and the buzzer does not sound when
the brake pedal is further depressed, slightly reduce the pressure on the
brake pedal (do not allow the vehicle to roll backward) and then firmly
depress it again. If the system still does not operate, check if the operat-
ing conditions explained above have been met.
Hill-start assist control buzzer
When hill-start assist control is activated, the buzzer will sound once.
In the following situations, hill-start assist control will be canceled and
the buzzer will sound twice.
• No attempt is made to drive the vehicle within approximately 2 sec-
onds of releasing the brake pedal.
• Push the P position switch.
• The parking brake is applied.
• The brake pedal is depressed again.
• The brake pedal has been depressed for more than approximately 3
minutes.
If the slip indicator comes on
It may indicate a malfunction in the system. Contact any authorized Lexus
dealer or repairer, or another duly qualified and equipped professional.

CAUTION
When raising your vehicle
Make sure to observe the following precautions to reduce the possibility of
death or serious injury:
When using a floor jack, follow the instructions of the manual provided
with the jack.
Do not use the jack that was supplied with your vehicle.
Do not put any part of your body underneath the vehicle when it is sup-
ported only by the floor jack.
Always use floor jack and/or automotive jack stands on a solid, flat, level
surface.
Do not start the hybrid system while the vehicle is supported by the floor
jack.
Stop the vehicle on level, firm ground, firmly set the parking brake and
shift the shift position to P.
Make sure to set the floor jack properly at the jack point.
Raising the vehicle with an improperly positioned floor jack will damage
the vehicle and may cause the vehicle to fall off the floor jack.
Do not raise the vehicle while someone is in the vehicle.
When raising the vehicle, do not place any object on top of or underneath
the floor jack.
Lift up the vehicle using a floor jack
such as the one shown in the illustra-
