warning CHEVROLET IMPALA 2010 9.G Manual PDF

Speedometer and OdometerThe speedometer shows the vehicle’s speed in both
miles per hour (mph) and kilometers per hour (km/h).
The odometer shows how far the vehicle has been
driven in either miles (used in the United States) or
in kilometers (used in Canada).
This vehicle has a tamper-resistant odometer. If the
odometer displays ERROR, it probably has been
tampered with and the numbers might not be accurate.
If the vehicle needs a new odometer installed, it
must be set to the mileage total of the old odometer.
If that is not possible, then it will be set at zero and
a label must be put on the driver’s door to show the old
mileage reading of the vehicle when the new odometer
was installed.TachometerThe tachometer displays the engine speed in revolutions
per minute (rpm).
Notice:If the engine is operated with the tachometer
in the shaded warning area, the vehicle could be
damaged, and the damages would not be covered by
the vehicle warranty. Do not operate the engine with
the tachometer in the shaded warning area.
Safety Belt RemindersSafety Belt Reminder LightWhen the engine is started, a chime sounds for
several seconds to remind a driver to fasten the safety
belt, unless the driver safety belt is already buckled.
The safety belt light comes
on and stays on for several
seconds, then flashes for
several more.
This chime and light are repeated if the driver remains
unbuckled and the vehicle is in motion. If the driver
safety belt is already buckled, neither the chime nor
the light comes on.

if the passenger airbag is enabled. SeePassenger
Sensing System on page 2-66for more information.
The passenger safety belt light, located on the instrument
panel, comes on and stays on for several seconds and
then flashes for several more.
This chime and light are
repeated if the passenger
remains unbuckled and
the vehicle is in motion.
If the passenger safety belt is buckled, neither the
chime nor the light comes on.
The front passenger safety belt warning light and chime
may turn on if an object is put on the seat such as a
briefcase, handbag, grocery bag, laptop or other
electronic device. To turn off the warning light and or
chime, remove the object from the seat or buckle the
safety belt.
Airbag Readiness LightThe system checks the airbag’s electrical system for
possible malfunctions. If the light stays on it indicates
there is an electrical problem. The system check includes
the airbag sensor, the pretensioners, the airbag modules,
the wiring and the crash sensing and diagnostic module.

4-25

If the word ON or the on symbol is lit on the passenger
airbag status indicator, it means that the right front
passenger frontal airbag is enabled (may inflate).
If the word OFF or the off symbol is lit on the airbag
status indicator, it means that the passenger sensing
system has turned off the right front passenger
frontal airbag.
If, after several seconds, both status indicator lights
remain on, or if there are no lights at all, there may be
a problem with the lights or the passenger sensing
system. See your dealer/retailer for service.

Emissions Inspection and Maintenance
ProgramsSome state/provincial and local governments have or
might begin programs to inspect the emission control
equipment on the vehicle. Failure to pass this inspection
could prevent getting a vehicle registration.
Here are some things to know to help the vehicle pass
an inspection:•
The vehicle will not pass this inspection if the check
engine light is on with the engine running, or if the
key is in ON/RUN and the light is not on.
•
The vehicle will not pass this inspection if the OBD II
(on-board diagnostic) system determines that critical
emission control systems have not been completely
diagnosed by the system. The vehicle would be
considered not ready for inspection. This can happen
if the battery has recently been replaced or if the
battery has run down. The diagnostic system is
designed to evaluate critical emission control
systems during normal driving. This can take several
days of routine driving. If this has been done and the
vehicle still does not pass the inspection for lack of
OBD II system readiness, your dealer/retailer can
prepare the vehicle for inspection.
Oil Pressure Light
{
WARNING:
Do not keep driving if the oil pressure is low.
The engine can become so hot that it catches fire.
Someone could be burned. Check the oil as soon
as possible and have the vehicle serviced.
Notice:Lack of proper engine oil maintenance
can damage the engine. The repairs would not be
covered by the vehicle warranty. Always follow
the maintenance schedule in this manual for
changing engine oil.
