WARNING
■For safe use
Do not rely solely upon the system. Relying solely upon the system may
lead to an unexpected accident.
● Driving safely is the sole responsibility of the driver. Pay careful attention
to the surrounding conditions in order to ensure safe driving. The Intelli-
gent Clearance Sonar function can provide support to lessen the severity
of collisions. However, it may not operate depending on the situation.
● The Intelligent Clearance Sonar function is not a system designed to com-
pletely stop the vehicle. Furthermore, even if the Intelligent Clearance
Sonar function is able to stop the vehicle, brake control is canceled after
approximately 2 seconds, so depress the brake pedal immediately.
■ In order for the system to operate properly
Make sure to observe the following precautions regarding the sensors
(→ P. 346). Failure to observe these precautions may cause the sensors
not to operate properly, and may result in an unexpected accident.
● Do not perform work such as modification, disassembly or painting
● Only perform replacements using genuine parts
● Do not subject the area around the sensors to any impacts
● Do not damage the sensors, and always keep them clean
■ Handling the suspension
Do not modify the suspension, as changes to the height or incline of the
vehicle may prevent the sensors from correctly detecting obstacles, may
cause the system not operate, or may cause the system to operate unnec-
essarily.

4-5. Using the driving support systems
Driving assist systems
◆ECB (Electronically Controlled Brake System)
The electronically controlled system generates braking force corre-
sponding to the brake operation
◆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
◆TRAC (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
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 supple-
mentary and should not be relied upon too heavily when operat-
ing the vehicle.

Driving
WARNING
■The ABS does not operate effectively when
● The limits of tire gripping performance have been exceeded (such as
excessively worn tires on a snow covered road).
● The vehicle hydroplanes while driving at high speed on wet or slick road.
■ Stopping distance when the ABS is operating may exceed that of nor-
mal conditions
The ABS is not designed to shorten the vehicle’s stopping distance. Always
maintain a safe distance from the vehicle in front of you, especially in the
following situations:
● When driving on dirt, gravel or snow-covered roads
● When driving with tire chains
● When driving over bumps in the road
● When driving over roads with potholes or uneven surfaces
■ TRAC/VSC may not operate effectively when
Directional control and power may not be achievable while driving on slip-
pery road surfaces, even if the TRAC/VSC systems are operating.
Drive the vehicle carefully in conditions where stability and power may be
lost.
■ Hill-start assist control does not operate effectively when
● Do not overly rely on the hill-start assist control. The hill-start assist control
may not operate effectively on steep inclines and roads covered with ice.
● Unlike the parking brake, hill-start assist control is not intended to hold the
vehicle stationary for an extended period of time. Do not attempt to use
hill-start assist control to hold the vehicle on an incline, as doing so may
lead to an accident.
■ When the TRAC, VSC an d/or ABS is activated
The slip indicator light flashes. Always drive carefully. Reckless driving may
cause an accident. Exercise particular care when the indicator light flashes.

4-5. Using the driving support systems
WARNING
■When the TRAC/VSC systems are turned off
Be especially careful and drive at a speed appropriate to the road condi-
tions. As these are systems to help ensure vehicle stability and driving
force, do not turn the TRAC/VSC systems off unless necessary.
■ Replacing tires
Make sure that all tires are of the specified size and of the same brand,
tread pattern and total load capacity. In addition, make sure that the tires are
inflated to the recommended tire inflation pressure level.
The ABS, VSC and TRAC and other driving assist systems will not function
correctly if different tires are installed on the vehicle.
Contact your Toyota dealer for further information when replacing tires or
wheels.
■ Handling of tires and the suspension
Using tires with any kind of problem or modifying the suspension will affect
the driving assist systems, and may cause a system to malfunction.

4-6. Driving tips

Driving
Hybrid vehicle driving tips
◆Using Eco drive mode
When using Eco drive mode, the torque corresponding to the accel-
erator pedal depression amount can be generated more smoothly
than it is in normal conditions. In addition, the operation of the air
conditioning system (h eating/cooling) will be minimized, improving
the fuel economy. ( →P. 318)
◆Use of Hybrid System Indicator
The Eco-friendly driving is possible by keeping the Hybrid System
Indicator within Eco area. ( →P. 1 1 9 )
◆Shift position operation
Shift the shift position to D when st opped at a traffic light, or driving
in heavy traffic etc. Shift the sh ift position to P when parking. When
using the N, there is no positive effect on fuel consumption. In the
N, the gasoline engine operates but electricity cannot be gener-
ated. Also, when using the air cond itioning system, etc., the hybrid
battery (traction batter y) power is consumed.
◆Accelerator pedal/brake pedal operation
●Drive your vehicle smoothly. Avoid abrupt acceleration and
deceleration. Gradual accelerati on and deceleration will make
more effective use of the electric motor (traction motor) without
having to use gasoline engine power.
● Avoid repeated acceleration. Repeated acceleration consumes
hybrid battery (traction battery) power, resulting in poor fuel con-
sumption. Battery power can be restored by driving with the
accelerator pedal slightly released.
For economical and ecological driv ing, pay attention to the fol-
lowing points:
