• Vehicle speed above 47 mph (75 kmh)
• Ascending a hill
• Charge level of high voltage battery is low
• Very high or low outside temperature (to provide system

cooling/heating)

• Engine not warm enough to provide passenger requested cabin

temperature

Stopping: The gas engine may shut off to conserve fuel as you come to
a stop. Restarting the vehicle is not required. Simply step on the
accelerator when you are ready to drive.

Transmission Operation: Due to the technologically advanced,
electronically-controlled Continuously Variable Transaxle (eCVT) you will
not feel shift changes like those of a non-hybrid vehicle. Your hybrid’s
transmission is designed to do its work seamlessly.

Since engine speed is controlled by the transmission, it may seem
elevated at times. This is normal hybrid operation and helps
deliver fuel efficiency and performance.

Neutral: It is not recommended to idle the vehicle in N (Neutral) for
extended periods of time because this will discharge your high voltage
battery and decrease fuel economy. Because of the unique nature of the
hybrid vehicle, the engine will not start in the N (Neutral) position. Also,
the engine cannot provide power to the hybrid system in N (Neutral).

Low Gear: L (Low gear) is designed to mimic the enhanced engine
braking available in non-hybrid vehicles. L (Low gear) will produce high
engine speeds to provide necessary engine braking. This is normal and
will not damage your vehicle. In L (Low gear) the gas engine will remain
on more often than in D (Drive gear).

Reverse: R (Reverse gear) vehicle speed is limited to 22 mph
(35 km/h).

Unique Hybrid operating characteristics

Your Hybrid, with its new technology, behaves differently compared to a
non-hybrid. Here is a description of the major differences:

Battery: Your Hybrid is equipped with a high voltage battery. A cool
battery ensures battery life and provides the best possible performance.
Your hybrid high voltage battery may periodically re-condition itself to
ensure maximum efficiency. You may notice slight changes in drivability
during this process, but it’s an important part of your hybrid’s high
voltage battery optimization features.
