Power distribution box
The power distribution box is located in the engine compartment. The
power distribution box contains high-current fuses that protect your
vehicle’s main electrical systems from overloads.
Always disconnect the battery before servicing high current
fuses.
To reduce risk of electrical shock, always replace the cover to
the Power Distribution Box before reconnecting the battery or
refilling fluid reservoirs.
If the battery has been disconnected and reconnected, refer to the
Batterysection of theMaintenance and Specificationschapter.
The high-current fuses are coded as follows:

Roadside Emergencies

•Automotive fuels can be harmful or fatal if swallowed. Fuel such as
gasoline is highly toxic and if swallowed can cause death or permanent
injury. If fuel is swallowed, call a physician immediately, even if no
symptoms are immediately apparent. The toxic effects of fuel may not
be visible for hours.
•Avoid inhaling fuel vapors. Inhaling too much fuel vapor of any kind
can lead to eye and respiratory tract irritation. In severe cases,
excessive or prolonged breathing of fuel vapor can cause serious
illness and permanent injury.
•Avoid getting fuel liquid in your eyes. If fuel is splashed in the eyes,
remove contact lenses (if worn), flush with water for 15 minutes and
seek medical attention. Failure to seek proper medical attention could
lead to permanent injury.
•Fuels can also be harmful if absorbed through the skin. If fuel is
splashed on the skin and/or clothing, promptly remove contaminated
clothing and wash skin thoroughly with soap and water. Repeated or
prolonged skin contact with fuel liquid or vapor causes skin irritation.
•Be particularly careful if you are taking “Antabuse” or other forms of
disulfiram for the treatment of alcoholism. Breathing gasoline vapors,
or skin contact could cause an adverse reaction. In sensitive
individuals, serious personal injury or sickness may result. If fuel is
splashed on the skin, promptly wash skin thoroughly with soap and
water. Consult a physician immediately if you experience an adverse
reaction.
When refueling always shut the engine off and never allow
sparks or open flames near the filler neck. Never smoke while
refueling. Fuel vapor is extremely hazardous under certain conditions.
Care should be taken to avoid inhaling excess fumes.
The flow of fuel through a fuel pump nozzle can produce static
electricity, which can cause a fire if fuel is pumped into an
ungrounded fuel container.

Refueling
Fuel vapor burns violently and a fuel fire can cause severe
injuries. To help avoid injuries to you and others:
•Read and follow all the instructions on the pump island;
•Turn off your engine when you are refueling;
•Do not smoke if you are near fuel or refueling your vehicle;
•Keep sparks, flames and smoking materials away from fuel;
•Stay outside your vehicle and do not leave the fuel pump unattended
when refueling your vehicle — this is against the law in some places;
•Keep children away from the fuel pump; never let children pump fuel.
Use the following guidelines to avoid electrostatic charge build-up when
filling an ungrounded fuel container:
•Place approved fuel container on the ground.
•DO NOT fill a fuel container while it is in the vehicle (including the
cargo area).
•Keep the fuel pump nozzle in contact with the fuel container while
filling.
•DO NOT use a device that would hold the fuel pump handle in the fill
position.
Fuel Filler Cap
Your fuel tank filler cap has an indexed design with a 1/4 turn on/off
feature.
When fueling your vehicle:
1. Turn the engine off.
2. Carefully turn the filler cap counterclockwise 1/4 turn until it stops.
3. Pull to remove the cap from the fuel filler pipe.
4. To install the cap, align the tabs on the cap with the notches on the
filler pipe.
5. Turn the filler cap clockwise 1/4 of a turn until at least a few clicks are
heard.
If the
symbol comes on and stays on after you start the engine, the
fuel filler cap may not be properly installed. Turn off the engine, remove
the fuel filler cap, align the cap properly and reinstall it.

6. Remove the air filter element
from the air filter housing.
7. Install a new air filter element.
8. Replace the air filter housing
cover and secure the clamps. Be
careful not to crimp the filter
element edges between the air filter
housing and cover and ensure that
the tabs on the edge are properly
aligned into the slots.
9. Slip the air tube onto the air filter
housing and tighten the air-tube
clamp bolt snugly, but do not
overtighten it.
10. Reconnect the Mass Air Flow
Sensor electrical connector to the
outlet tube. Make sure the locking
tab on the connector is in the
“locked” position (connector shown
from below for clarity).
