Chevrolet Impala Owner Manual - 2011
Instruments and Controls
5-19
Light On Steady:
An emission
control system malfunction has
been detected on the vehicle.
Diagnosis and service might be
required.
The following may correct an
emissions system malfunction:
.
Make sure the fuel cap is fully
installed. See
Filling the Tank on
page 9
‑
39
. The diagnostic
system can determine if the
fuel cap has been left off or
improperly installed. A loose or
missing fuel cap allows fuel to
evaporate into the atmosphere.
A few driving trips with the cap
properly installed should turn the
light off.
.
Make sure the electrical system
is not wet. The system could
be wet if the vehicle was driven
through a deep puddle of
water. The condition is usually
corrected when the electrical
system dries out. A few driving
trips should turn the light off.
.
Make sure to fuel the vehicle
with quality fuel. Poor fuel quality
causes the engine not to run as
efficiently as designed and can
cause: stalling after start-up,
stalling when the vehicle is
changed into gear, misfiring,
hesitation on acceleration,
or stumbling on acceleration.
These conditions might go away
once the engine is warmed up.
If one or more of these
conditions occurs, change the
fuel brand used. It will require
at least one full tank of the
proper fuel to turn the light off.
See
Recommended Fuel on
page 9

.
If none of the above have made
the light turn off, your dealer can
check the vehicle. The dealer
has the proper test equipment
and diagnostic tools to fix any
mechanical or electrical problems
that might have developed.
Emissions Inspection and
Maintenance Programs
Some state/provincial and
local governments may have
programs to inspect the on-vehicle
emission control equipment.
For the inspection, the emission
system test equipment is connected
to the vehicle
’
s Data Link
Connector (DLC).
The DLC is under the instrument
panel to the left of the steering
wheel. See your dealer if assistance
is needed.
