Running When:
• The engine, transmission, or
hybrid battery is not warmed
up yet.
• The outside temperature is
high — usually above
95°F (35°C) and the climate
control system is working to
cool the vehicle in A/C mode
(yellow light illuminated on
A/C button) or if defrost is
selected. See Automatic Climate
Control System on page 3-17
for more information.
• The shift lever is in P (Park),

The Engine Will Restart When:

to P (Park), R (Reverse),
N (Neutral) or M (Manual Mode),
the engine will restart
immediately.
• If the A/C button (green light
illuminated on A/C) button 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.

or normal A/C, or floor/
defog/defrost) See Automatic
Climate Control System on
page 3-17 for more information.

either heater or climate control
performance. See “Air
Conditioning and Engine
Start/Stop” under Automatic
Climate Control System on
page 3-17 for more information.
