• Very high or low outside temperature

(to provide system cooling or heating)

For C-MAX Energi vehicles, climate

control demands by passengers may

not directly cause the engine to run.

This only occurs when the high voltage

battery charge is low, or if the outside

temperature is cold enough to require

the engine to provide additional heat

for the cabin.

• 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, you will not feel shift

changes like those of a non-hybrid vehicle.

Note: 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 position N for an extended period

of time because this will discharge your

high voltage battery and decrease fuel

economy. The engine will not start or stop,

and cannot provide power to the hybrid

system in position N.

Low Gear: Low gear (position L) is

designed to mimic the enhanced engine

braking available in non-hybrid vehicles.

Low gear will produce high engine speeds

to provide necessary engine braking. This

is normal and will not damage your vehicle.

In low gear, the gas engine will remain on

more often than in position D.

Reverse: In position R, vehicle speed is

limited to 22 mph (35 km/h).

Unique Hybrid Operating

Characteristics

Your vehicle 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 driveability during

this process, but it is an important part of

your hybrid's high voltage battery

optimization features.

The high voltage battery is cooled by cabin

air drawn from vent holes in the trim panels

behind the rear seats. Avoid placing objects

at the vent holes that block airflow to the

high voltage battery.

Engine: The engine speed in your hybrid

is not directly tied to your vehicle speed.

Your vehicle's engine and transmission are

designed to deliver the power you need at

the most efficient engine speed. During

heavy accelerations, your hybrid may reach

high engine speeds (up to 6000 RPM).

In prolonged mountainous driving, you may

see the engine tachometer changing

without your input. This is intentional and

maintains the battery charge level. You

may also notice during extended downhill

driving that your engine continues to run

instead of shutting off.

During this engine braking, the engine stays

on, but it is not using any fuel. You may also

hear a slight whine or whistle when

operating your vehicle. This is the normal

operation of the electric generator in the

hybrid system.
