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
TRC (Traction Control)
Helps to maintain drive power and prevent the drive wheels from
spinning when starting the vehicle or accelerating on slippery roads
Hill-start assist control
Prevents the vehicle from rolling backward when starting on an
incline or slippery slope
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.

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.
Operating conditions of hill-start assist control
When the following four conditions are met, the hill-start assist control will
operate:
The shift lever is in a position other than P or N (when starting off forward/
backward on an upward incline).
The vehicle is stopped.
The accelerator pedal is not depressed.
The parking brake is not engaged.
Automatic system cancelation of hill-start assist control
The hill-start assist control will turn off in any of the following situations:
The shift lever is moved to P or N.
The accelerator pedal is depressed.
The parking brake is engaged.
Approximately 2 seconds elapse after the brake pedal is released.
Operating conditions of emergency brake signal
When the following three conditions are met, the emergency brake signal will
operate:
The emergency flashers are off.
Actual vehicle speed is over 55 km/h (35 mph).
The brake pedal is depressed in a manner that cause the system to judge
from the vehicle deceleration that this is a sudden braking operation.
Automatic system cancelation of emergency brake signal
The emergency brake signal will turn off in any of the following situations:
The emergency flashers are turned on.

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 roads.
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 roads with uneven surfaces
TRC may not operate effectively when
Directional control and power may not be achievable while driving on slip-
pery road surfaces, even if the TRC system is operating.
Do not drive the vehicle 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 VSC is activated
The slip indicator light flashes. Always drive carefully. Reckless driving may
cause an accident. Exercise particular care when the indicator light flashes.
When the TRC/VSC systems are turned off
Be especially careful and drive at a speed appropriate to the road condi-
tions. As these are the systems to help ensure vehicle stability and driving
force, do not turn the TRC/VSC systems off unless necessary.

WARNING
Replacing tires
Make sure that all tires are of the specified size, 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, TRC and VSC systems will not function correctly if different tires
are installed on the vehicle.
Contact any authorized Toyota dealer or repairer, or another duly qualified
and equipped professional 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.

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 (heating/cooling) will be minimized, improving
the fuel economy. (P. 189)
Use of Hybrid System Indicator
The Eco-friendly driving is possible by keeping the indicate of
Hybrid System Indicator within Eco area. (P. 97)
Shift lever operation
Shift the shift lever to D when stopped at a traffic light, or driving in
heavy traffic etc. Shift the shift lever 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 generated. Also,
when using the air conditioning system, etc., the hybrid battery
(traction battery) power is consumed.
For economical and ecological driving, pay attention to the fol-
lowing points:

2204-6. Driving tips
Acceleration pedal/brake pedal operation
Drive your vehicle smoothly. Avoid abrupt acceleration and
deceleration. Gradual acceleration 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.
When braking
Make sure to operate the brakes gently and in a timely manner. A
greater amount of electrical energy can be regenerated when slow-
ing down.
Delays
Repeated acceleration and deceleration, as well as long waits at
traffic lights, will lead to bad fuel economy. Check traffic reports
before leaving and avoid delays as much as possible. When driving
in a traffic jam, gently release the brake pedal to allow the vehicle to
move forward slightly while avoiding overuse of the accelerator
pedal. Doing so can help control excessive gasoline consumption.
Highway driving
Control and maintain the vehicle at a constant speed. Before stop-
ping at a toll booth or similar, allow plenty of time to release the
accelerator and gently apply the brakes. A greater amount of elec-
trical energy can be regenerated when slowing down.
