The Engine Will Restart When:
. The brake pedal is released.
. The accelerator pedal is applied.
. Shifting out of D (Drive) to any
other gear.
. If eco air conditioning is
selected, the duration of the auto
stop will depend on the outside
temperature. This economy
mode improves fuel economy by
limiting the effects of the air
conditioning. The warmer it is
outside, the shorter the time
before the engine is restarted to
provide cabin cooling.

turned from off to normal air
conditioning or defrost. See
Dual
Automatic Climate Control
System on page 8

either heater or climate control
performance. See
Dual
Automatic Climate Control
System on page 8
‑ 3 for more
information.
. The high voltage battery pack
charge is low and requires
recharging.

two minutes.

Engine Heater
The engine coolant heater,
if available, can help in cold weather
conditions at or below
− 18°C (0°F)
for easier starting and better fuel
economy during engine warm-up.
Plug in the coolant heater at least
four hours before starting the
vehicle. An internal thermostat in
the plug-end of the cord will prevent
engine coolant heater operation at
temperatures above
− 18°C (0°F).
To Use the Engine Coolant
Heater
1. Turn off the engine.
2. Open the hood and unwrap the
electrical cord.
