The OBD-II system is designed to check the emission control system
during normal driving. A complete check may take several days. If the
vehicle is not ready for I/M testing, the following driving cycle consisting
of mixed city and highway driving may be performed:
15 minutes of steady driving on an expressway/highway followed by 20
minutes of stop-and-go driving with at least four 30-second 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. If
the vehicle is still not ready for I/M testing, the above driving cycle will
have to be repeated.
BRAKE FLUID
The fluid level will drop slowly as
the brakes wear, and will rise when
the brake components are replaced.
Fluid levels between the “MIN” and
“MAX” lines are within the normal
operating range; there is no need to
add fluid. If the fluid levels are
outside of the normal operating
range the performance of the
system could be compromised; seek
service from your authorized dealer
immediately.
TRANSMISSION FLUID
Checking automatic transmission fluid
Refer to your scheduled maintenance information for scheduled
intervals for fluid checks and changes. Your transaxle does not consume
fluid. However, the fluid level should be checked if the transaxle is not
working properly, i.e., if the transaxle slips or shifts slowly or if you
notice some sign of fluid leakage.
Automatic transmission fluid expands when warmed. To obtain an
accurate fluid check, drive the vehicle until it is warmed up
(approximately 20 miles [30 km]). If your vehicle has been
operated for an extended period at high speeds, in city traffic
during hot weather or pulling a trailer, the vehicle should be
turned off for about 30 minutes to allow fluid to cool before
checking.
