function. The brake pedal has a lighter effort (longer
travel) than during normal driving but provides full
power assist.
Climate Control (HVAC System)
Your Hybrid vehicle uses automatic temperature control
(ATC) HVAC system with specialized components. This
HVAC system utilizes a humidity sensor, cabin infrared
(IR) sensor, sun sensor, and ambient temperature sensor
to choose operation mode and control cabin comfort.
Your Hybrid vehicle also uses a heater auxiliary pump to
provide heat to the cabin while the vehicle is in electric
mode. The electrically driven AC compressor is not
connected to the engine like a standard gas vehicle. These
components allow the control to operate the HVAC
system in a very efficient manner to save fuel.
NOTE: It is recommended the vehicle be operated with
the air conditioning (AC) on in high ambient tempera-
tures as the high voltage battery is cooled by the cabin air.
Driving To Achieve Maximum Fuel Economy
Your fuel economy should improve throughout your
Hybrid vehicle’s break-in period. As with any vehicle,
fuel economy can be significantly impacted by your
driving style and accessory usage. For best results, keep
in mind the following:
Tire Inflation
Keep tires properly inflated and only use the recom-
mended size. Refer to “Tire and Loading Information
Placard” under “Tires Safety Information” in Section 5 of
your Owner’s Manual.
Driving Style
Aggressive driving increases the amount of energy re-
quired to move your vehicle. In general, better fuel
economy is achieved with mild to moderate acceleration
and deceleration.
