FEATURES/ OPERATIONS
Starting the hybrid system
The Hybrid Synergy Drive System utilizes a computer-controlled gasoline engine
and electric motor to provide the most efficient combination of power for the
vehicle. To conserve energy, when the brakes are applied the braking force
generates electricity which is then sent to the traction battery. In addition, the
engine shuts off when the vehicle is stopped. The benefits are better fuel
economy, reduced vehicle emissions and improved performance.
NOTE: Fuel consumption and energy information of the hybrid system are shown
on the multi-information display.
Tips for improved fuel economy
-Ensure tire pressures are maintained at levels specified in the Owner’s Manual.
-When possible, link trips to reduce engine cold starts.
-Avoid driving at speeds that are higher than necessary, especially on the highway.
-When possible, avoid sudden stops to maximize regenerative braking energy.
-Minimize use of the Air Conditioning.

Auto lock/ unlock
Automatic door locks can be programmed to operate in two different modes, or
turned OFF.
-Doors lock when shifting from Park.
-Doors lock when the vehicle speed is approximately 12 mph or higher.
-Doors unlock when shifting into Park.
-Doors unlock when the driver’s door is opened within 10 seconds after turning the
“POWER” switch OFF.
Refer to the Owner’s Manualfor more details.(1) Depress the brake pedal, and
press the “POWER” switch
briefly and firmly.
(2) The “READY” light will blink.
After a few seconds, when the
light remains steady and a
beep sounds, you may begin
driving.

HAC helps prevent rolling backwards on an incline. To engage, push further down
on brake pedal while at a complete stop until a beep sounds and slip indicator
illuminates. HAC holds for approximately two seconds after releasing brake pedal.
Refer to the Owner’s Manualfor more details.

Star Safety SystemTM
VSC helps prevent loss of traction during cornering by reducing engine power and
applying brake force to selected wheels.
Toyota’s VSC monitors steering angle and the direction your vehicle is traveling.
When it senses that the front or rear wheels begin to lose traction, VSC reduces
engine power and applies braking to selected wheels. This helps restore traction
and vehicle control.
Vehicle Stability Control (VSC)
Anti-Lock Brake System (ABS)
Brake Assist (BA)
ABS helps prevent brakes from locking up by "pulsing" brake pressure to each
wheel. This limits brake lockup and provides the maximum brake effectiveness for
the current road conditions.
Toyota's ABS sensors detect which wheels are locking up and limits wheel lockup by
"pulsing" each wheel's brakes independently. Pulsing releases brake pressure
repeatedly for fractions of a second. This helps the tires attain the maximum
traction that the current road conditions will allow, helping you stay in control.
Brake Assist is designed to detect sudden or “panic” braking, and then add braking
pressure to decrease the vehicle’s stopping distance. When there’s only a split
second to react, Brake Assist can add additional brake pressure more quickly than
just the driver alone can. VSC helps prevent loss of traction during cornering by reducing engine power, and
Traction Control helps maintain traction on loose gravel and wet, icy, or uneven
surfaces by applying brake force to the spinning wheel(s).
Toyota’s TRAC sensors are activated when one of the drive wheels starts to slip.
TRAC limits engine output and applies the brakes to the spinning wheel. This
transfers power to the wheels that still have traction to help you drive safely.
Traction Control (TRAC)
Electronic Brake Force Distribution (EBD)
Toyota’s ABS technology has Electronic Brake-force Distribution (EBD) to help
maintain stability and balance when braking. Abrupt stops cause the vehicle to tilt
forward, reducing the braking power of the rear wheels. EBD responds to sudden
stops by redistributing brake force to maximize the braking effectiveness of all
four wheels.
SAFETY AND EMERGENCY FEATURES
All new Toyota vehicles come standard with the Star Safety SystemTM, which
combines Vehicle Stability Control (VSC), Traction Control (TRAC), Anti-lock Braking
System (ABS), Electronic Brake-force Distribution (EBD), Brake Assist (BA) and
Smart Stop Technology (SST).

27 There are two types of Toyota floor mats: carpeted and all-weather. Each vehicle
has model-specific floor mats. Installation is easy.
For safety, follow these steps:
• Only use floor mats designed for your specific model.
• Use only one floor mat at a time, using the retaining hooks to keep the mat in
place.
• Install floor mats right side up.

Smart Stop Technology automatically reduces engine power when the accelerator
and brake pedals are pressed simultaneously under certain conditions.
SST engages when the accelerator is depressed first and the brakes are applied
firmly for longer than one-half second at speeds greater than five miles per hour.
SST doesn’t engage if the brake pedal is depressed before the accelerator pedal,
allowing vehicles to start on a steep hill and safely accelerate without rolling
backward.
