Hybrid Synergy Drive System
FEATURES & OPERATIONS
The Hybrid Synergy Drive System utilizes a computer-controlled gasoline \
engine
and electric motor to provide the most efficient combination of power fo\
r the
vehicle. To conserve energy, when the brakes are applied the braking for\
ce
generates electricity which is then sent to the traction battery. In add\
ition, the
engine shuts off when the vehicle is stopped. The benefits are better fu\
el economy,
reduced vehicle emissions and improved performance.
NOTE: Fuel consumption and energy information of the Hybrid System are shown on the Multi-Information Display.
-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 t\
he highway.
-When possible, avoid sudden stops to maximize regenerative braking ener\
gy.
-Minimize use of the air conditioning.
TIPS FOR IMPROVED FUEL ECONOMY
STARTING YOUR VEHICLE
Auto lock/unlock
Automatic door locks can be programmed to operate in different modes, or\
turned
OFF.
Shift position linked door locking/unlocking function
-Doors lock when shifting from Park.
-Doors unlock when shifting into Park.
Speed linked door locking function
-Doors lock when the vehicle speed is approximately 12 mph or higher.
Driver’s door linked door unlocking function
-Doors unlock when the “POWER” switch is set to OFF and driver’\
s door is opened within approximately 45 seconds.
Refer to the Owner’s Manual for more details.
Push
(1) Put the shift lever in “P.”
(2) Depress the brake pedal, and “”
will be displayed on the Multi-Information
Display.
(3) Press the “POWER” switch briefly and
firmly.
(4) The “READY” light will blink. After
a few seconds, when the light remains
steady and a beep sounds, you may
begin driving.

SAFETY & EMERGENCY FEATURES
Star Safety System™
ANTI-LOCK BRAKE SYSTEM (ABS)
Toyota’s ABS sensors detect which wheels are locking up and limits wh\
eel lockup
by “pulsing” each wheel’s brakes independently. Pulsing release\
s brake pressure
repeatedly for fractions of a second. This helps the tires attain the tr\
action that
current road conditions will allow, helping you to stay in directional c\
ontrol.
BRAKE ASSIST (BA)
Brake Assist is designed to detect sudden or “panic” braking, and \
then add braking
pressure to help decrease the vehicle’s stopping distance. When there\
’s only a split
second to react, Brake Assist can add additional brake pressure more qui\
ckly than
just the driver alone can.
ENHANCED VEHICLE STABILITY CONTROL (VSC)
Enhanced Vehicle Stability Control provides cooperative control of the A\
BS, TRAC,
VSC and EPS.
Enhanced VSC helps to maintain directional stability when loss of tracti\
on occurs
during a turn.
ELECTRONIC BRAKE FORCE DISTRIBUTION (EBD)
Toyota’s ABS technology has Electronic Brake-force Distribution (EBD) to help
maintain control and balance when braking. EBD responds to sudden stops \
by
redistributing brake force to enhance the braking effectiveness of all f\
our wheels. Your vehicle comes standard with the Star Safety System
TM, which combines Anti-
lock Braking System (ABS), Brake Assist (BA), Electronic Brake-force Distribution
(EBD), Smart Stop Technology (SST), Traction Control (TRAC) and Vehicle Stability
Control (VSC).
Refer to the Owner’s Manual for more details and important information on limitations
to these systems.
SMART STOP TECHNOLOGY (SST)
Smart Stop Technology automatically reduces engine power when the accele\
rator
and brake pedals are pressed simultaneously under certain conditions.
SST engages when the accelerator is depressed first and the brakes are a\
pplied
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 acceler\
ator pedal,
allowing vehicles to start on a steep hill and safely accelerate without\
rolling
backward.

Floor mat installation
There are two types of Toyota floor mats: carpeted and all-weather. Each\
vehicle
has model-specific floor mats. Installation is easy.
To keep your floor mat properly positioned, follow these steps:
• Only use Toyota 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.
Always align the marks
TRACTION CONTROL (TRAC)
VSC helps prevent loss of traction during cornering by reducing engine p\
ower, and
Traction Control helps maintain traction on loose gravel and wet, icy, o\
r uneven
surfaces by applying brake force to the spinning wheel(s).
Toyota’s TRAC sensors are activated when one of the drive wheels star\
ts 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 keep you \
on track.
