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 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.
-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.
(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.

SWITCHING TO CONSTANT SPEED (CRUISE) CONTROL MODE
Note: When your vehicle is too close to a vehicle ahead, and sufficient automatic
deceleration via the cruise control is not possible, the display will flash and the
buzzer will sound to alert the driver. An example of this would be if another driver
cuts in front of you while you are following a vehicle. Depress the brake pedal to
ensure an appropriate vehicle-to-vehicle distance.
If you are already using DRCC “”, push ON-OFF button to turn the system off
first, then push and hold ON-OFF button for at least 1.5 seconds to switch.
