Roadside emergencies
143 Even after a fuse is replaced, it will
continue to blow if the cause of the
overload is not identified and
corrected. If the fuse continues to
blow, have the vehicle’s electrical
system checked by your dealer or a
qualified service technician.
To reset a circuit breaker press the
reset button.
The passenger compartment fuse
panel is located on the driver’s side
under the instrument panel. The
power distribution box is located
on the driver’s side of the engine
compartment.
They contain the main fuses and
the main relays. The circuits
protected are identified by
numbers on the passenger
compartment fuse panel and inside
the cover on the power distribution
box.
FUSES AND RELAYS
If electrical components in the
vehicle are not working, a fuse may
have blown. Blown fuses are
identified by a broken wire. Check
the appropriate fuses before
replacing any electrical
components.
Always replace a fuse with
one that has the specified
amperage rating. Using a fuse with
higher amperage rating can cause
severe wire damage and could
start a fire.

Maintenance and care
185 Relearning the idle function
Because your vehicle’s engine is
electronically controlled, some
control conditions are maintained
by power from the battery. When
the battery is disconnected or a
new battery is installed, the
computer must “relearn” its idle
conditions before your vehicle can
drive properly. To begin this
process:
1. Put the automatic transaxle
gearshift in P (Park). Put the
manual transaxle gearshift in
neutral.
2. Turn off all accessories and start
the vehicle.
3. Let the engine idle for at least
one minute.
4. The “relearning” process will
automatically complete as you
drive the vehicle.
• If you do not allow the engine to
“relearn” its idle, the idle quality of
your vehicle may be adversely
affected until the idle is eventually
“relearned”.
• If the battery has been
disconnected or if a new battery
has been installed, the clock and
preset radio stations must be reset
once the battery is reconnected.

Maintenance and care
205 If the vehicle’s powertrain system
or its battery has just been
serviced, the OBD-II system is
reset to a “not ready for I/M test“
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:
• First, at least 10 minutes of
driving on an expressway or
highway.
• Next, at least 20 minutes of
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.
