Electrical System
Electrical System Overload
The vehicle has fuses and circuit breakers to
protect against an electrical system
overload.
When the current electrical load is too
heavy, the circuit breaker opens and closes,
protecting the circuit until the current load
returns to normal or the problem is fixed.
This greatly reduces the chance of circuit
overload and fire caused by electrical
problems.
Fuses and circuit breakers protect power
devices in the vehicle. If there is a problem on the road and a fuse
needs to be replaced, the same amperage
fuse can be borrowed. Choose some feature
of the vehicle that is not needed to use and
replace it as soon as possible.
To check a fuse, look at the band inside the
fuse. If the band is broken or melted,
replace the fuse. Be sure to replace a bad
fuse with a fuse of the identical size and
rating.Replacing a Blown Fuse
1. Turn off the vehicle.
2. Locate the fuse puller in the engine
compartment fuse block.

remainder of the ignition cycle. A DIC
warning message may also display. The
malfunction light and DIC warning message,
if equipped, come on at each ignition cycle
until the problem is corrected. Some of the
conditions that can cause these to come
on are:
.One of the road tires has been replaced
with the spare tire. The spare tire does
not have a TPMS sensor. The malfunction
light and the DIC message, if equipped,
should go off after the road tire is
replaced and the sensor matching process
is performed successfully. See "TPMS
Sensor Matching Process" later in this
section.
.The TPMS sensor matching process was
not done or not completed successfully
after rotating the tires. The malfunction
light and the DIC message, if equipped,
should go off after successfully
completing the sensor matching process.
See "TPMS Sensor Matching Process" later
in this section.
.One or more TPMS sensors are missing or
damaged. The malfunction light and the
DIC message, if equipped, should go off
when the TPMS sensors are installed and
the sensor matching process is performed
successfully. See your dealer for service.
.Replacement tires or wheels do not match
the original equipment tires or wheels.
Tires and wheels other than those
recommended could prevent the TPMS
from functioning properly. SeeBuying
New Tires 0298.
.Operating electronic devices or being near
facilities using radio wave frequencies
similar to the TPMS could cause the TPMS
sensors to malfunction.
If the TPMS is not functioning properly, it
cannot detect or signal a low tire pressure
condition. See your dealer for service if the
TPMS malfunction light and DIC message,
if equipped, come on and stay on.
Tire Fill Alert (If Equipped)
This feature provides visual and audible
alerts outside the vehicle to help when
inflating an underinflated tire to the
recommended cold tire pressure.
When the low tire pressure warning light
comes on: 1. Park the vehicle in a safe, level place.
2. Set the parking brake firmly.
3. Place the vehicle in P (Park). 4. Add air to the tire that is underinflated.
The turn signal lamp will flash. When
the recommended pressure is reached,
the horn sounds once and the turn signal
lamp will stop flashing and briefly turn
solid.
Repeat these steps for all underinflated tires
that have illuminated the low tire pressure
warning light.
{Warning
Overinflating a tire could cause the tire
to rupture and you or others could be
injured. Do not exceed the maximum
pressure listed on the tire sidewall.
See Tire Sidewall Labeling 0287 and
Vehicle Load Limits 0191.
If the tire is overinflated by more than
35 kPa (5 psi), the horn will sound multiple
times and the turn signal lamp will continue
to flash for several seconds after filling
stops.
To release and correct the pressure, while
the turn signal lamp is still flashing, briefly
press the center of the valve stem. When
the recommended pressure is reached, the
horn sounds once.
