TIPS FOR IMPROVED FUEL ECONOMY
DEFAULT SETTING
CUSTOMIZED SETTING
STARTING YOUR VEHICLE
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
and reduced vehicle emissions.
NOTE: Fuel consumption and energy information of the Hybrid System are
shown on the Audio Multimedia System screen or the navigation system (if
equipped).
1. Ensure tire pressures are maintained at levels specified in the Owner’s Manual.
2. When possible, link trips to reduce engine cold starts.
3. Avoid driving at speeds that are higher than necessary, especially on the highway.
4. When possible, avoid sudden stops to maximize regenerative braking energy.
5. Minimize use of the air conditioning.

OVERVIEW
FEATURES & OPERATIONS
TOYOTA SAFETY SENSE
SAFETY & EMERGENCY FEATURES
SMART STOP TECHNOLOGY (SST)
Star Safety System™
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.
Refer to the Brake Override System section in the Owner’s Manual for more
information on Smart Stop Technology.
ENHANCED VEHICLE STABILITY CONTROL (VSC)
Enhanced Vehicle Stability Control provides cooperative control of the ABS, TRAC,
VSC and EPS.
Enhanced VSC helps to maintain directional stability when loss of traction occurs
during a turn.
ANTI-LOCK BRAKE SYSTEM (ABS)
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 traction that
current road conditions will allow, helping you to stay in directional control.
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 quickly than
just the driver alone can.
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 four wheels.
Your vehicle comes standard with the Star Safety SystemTM, 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.

Floor mat installation
Always align the marks
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.
TRACTION CONTROL (TRAC)
VSC helps prevent loss of traction during cornering by reducing Hybrid System
output, 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 Hybrid System 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.
