AUTO-START-STOP

 (If Equipped)

The system helps reduce fuel consumption
by automatically stopping and restarting
the engine when your vehicle has stopped.
The engine restarts automatically when
you release the brake pedal.

In some situations, your vehicle may restart
automatically, for example:
•

To maintain interior comfort.

•

To recharge the battery.

Note: Power assist steering turns off when
the engine is off.

Note: If your vehicle is flex fuel capable,
Auto-Start-Stop will be inhibited for a short
time after a refuel event while the system
is verifying the fuel type being used.

WARNINGS

Always fully apply the parking brake.
Make sure you shift into park (P) for
vehicles with an automatic

transmission. Switch the ignition off and
remove the key whenever you leave your
vehicle.

Before opening the hood or
performing any maintenance, fully
apply the parking brake, shift into

park (P) or neutral (N) and switch the
ignition off.

Always switch the ignition off before

SAFETY PRECAUTIONS

WARNINGS

Do not overfill the fuel tank. The
pressure in an overfilled tank may
cause leakage and lead to fuel spray

and fire.

The fuel system may be under
pressure. If you hear a hissing sound
near the fuel filler inlet, do not refuel

until the sound stops. Otherwise, fuel may
spray out, which could cause serious
personal injury.

Fuels can cause serious injury or
death if misused or mishandled.

Fuel may contain benzene, which is
a cancer-causing agent.

When refueling always shut the
engine off and never allow sparks or
open flames near the fuel tank filler

valve. Never smoke or use a cell phone
while refueling. Fuel vapor is extremely
hazardous under certain conditions. Avoid
inhaling excess fumes.

Follow these guidelines when refueling:
•

Extinguish all smoking materials and
any open flames before refueling your
vehicle.

•

Always switch the engine off before
refueling.

•

Automotive fuels can be harmful or
fatal if swallowed. Fuel is highly toxic
and if swallowed can cause death or
permanent injury. If fuel is swallowed
immediately call a physician, even if no
symptoms are immediately apparent.
The toxic effects of fuel may not be
apparent for hours.

•

Avoid inhaling fuel vapors.  Inhaling fuel
vapor can lead to eye and respiratory
tract irritation.  In severe cases,
excessive or prolonged breathing of
fuel vapor can cause serious illness and
permanent injury.

•

Avoid getting fuel in your eyes. If you
splash fuel in your eyes, immediately
remove contact lenses (if worn), flush
with water for 15 minutes and seek
medical attention.  Failure to seek
proper medical attention could lead to
permanent injury.

•

Fuels can be harmful if absorbed
through the skin. If you splash fuel on
your skin, clothing or both, promptly
remove contaminated clothing and
thoroughly wash your skin with soap
and water. Repeated or prolonged skin
contact causes skin irritation.

•

Be particularly careful if you are taking
Antabuse or other forms of Disulfiram
for the treatment of alcoholism.
Breathing fuel vapors could cause an
adverse reaction, serious personal
injury or sickness. Immediately call a
physician if you experience any adverse
reactions.
