Maintenance and care
131

If you smell exhaust fumes
of any kind inside your
vehicle, have the dealer inspect
and fix your vehicle immediately.
Do not drive if you smell exhaust
fumes. These fumes are harmful
and could kill you.
Do not make any unauthorized
changes to your vehicle or engine.
By law, vehicle owners and anyone
who manufactures, repairs,
services, sells, leases, trades
vehicles, or supervises a fleet of
vehicles are not permitted to
intentionally remove an emission
control device or prevent it from
working. Information about your
vehicle's emission system is on the
Vehicle Emission Control
Information Decal located on or
near the engine. This decal
identifies engine displacement and
gives some tune up specifications.
Please consult your ªWarranty
Guideº for complete emission
warranty information.
Readiness for
inspection/maintenance
(I/M) testing
In some localities, it may be a legal
requirement to pass an I/M test of
the on-board diagnostic (OBD-II)

If the vehicle's powertrain system
or its battery has just been
serviced, the OBD-II system is
reset to a ªnot ready for I/M testº
condition. To ready the OBD-II
system for I/M testing, a minimum
of 30 minutes of city and highway
driving is necessary as described
below:
²First, at least 10 minutes of
driving on an expressway or
highway.
²Next, at least 20 minutes driving
in stop and go, city type traffic
with at least four idle periods.
Allow the vehicle to sit for at least
eight hours without starting the
engine. Then, start the engine and
complete the above driving cycle.
The engine must warm up to its
normal operating temperature.
Once started, do not turn off the
engine until the above driving
cycle is complete.
