Automatic Engine Start/Stop Override - GMC Hybrid 2007 Owner's Manual

Automatic Engine Start/Stop Override

The automatic engine start/stop override
feature may cause the engine to remain running at
a complete stop or may start the engine at a
complete stop. The following are reasons
why either of these conditions may be
encountered.
The engine will stay running at a complete stop or
will automatically start from a complete stop if:
•
The outside temperatures are high — usually
above 95°F (35°C). The climate control system
is working to cool the cabin in AUTO mode. See
Climate Controls on page 24.
•
You release the brake pedal in DRIVE (D) or
THIRD (3) — even slightly.
