Emissions Inspection and
Maintenance Programs
If the vehicle requires an Emissions
Inspection/Maintenance test, the
test equipment will likely connect to
the vehicle's Data Link
Connector (DLC).
The DLC is under the instrument
panel to the left of the steering
wheel. Connecting devices that are
not used to perform an Emissions
Inspection/Maintenance test or to
service the vehicle may affect
vehicle operation. SeeAdd-On
Electrical Equipment 0233. See
your dealer if assistance is needed.
The vehicle may not pass
inspection if:
. The light is on when the engine
is running. .
The light does not come on
when the vehicle is in
Service Mode.
. Critical emission control systems
have not been completely
diagnosed. If this happens, the
vehicle would not be ready for
inspection and might require
several days of routine driving
before the system is ready for
inspection. This can happen if
the 12-volt battery has recently
been replaced or run down, or if
the vehicle has been recently
serviced.
See your dealer if the vehicle will
not pass or cannot be made ready
for the test.
Brake System Warning
Light

of two hydraulic circuits. If one
circuit is not working, the remaining

performance, both circuits need to
be working. If the warning light comes on, there
is a brake problem. Have the brake
system inspected right away.

Programmable Charging
Important Information about
Portable Electric Vehicle Charging
. Charging an electric vehicle can
stress a building’ s electrical
system more than a typical
household appliance.
. Before plugging into any
electrical outlet, have a qualified
electrician inspect and verify the
electrical system (electrical
outlet, wiring, junctions, and
protection devices) for
heavy-duty service at a 12 amp
continuous load.
. Electrical outlets may wear out
with normal usage or may be
damaged over time, making
them unsuitable for electric
vehicle charging.
. Check the electrical outlet/plug
while charging and discontinue
use if the electrical outlet/plug is
hot, then have the electrical
outlet serviced by a qualified
electrician.
