FUSE SPECIFICATION CHART
Power Distribution Box
WARNINGS
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. The power distribution box is located in
the engine compartment. It has
high-current fuses that protect your
vehicle's main electrical systems from
overloads.
If the battery has been disconnected and
reconnected, some features will need to
be reset. See Changing the 12V Battery
(page 343).

ENGINE OIL CHECK - 6.2L/6.8L
To check the engine oil level consistently
and accurately, do the following: 1. Make sure that your vehicle is on level
ground.
2. Run engine until it reaches normal operating temperature.
3. Make sure the parking brake is on. Make
sure the transmission is in park (P) or
neutral (N).
4. Switch the engine off and wait 15 minutes for the oil to drain into the oil
pan. Checking the engine oil level too
soon after you switch the engine off
may result in an inaccurate reading.
5. Open the hood. See Opening and
Closing the Hood (page 320).
6. Remove the dipstick and wipe it with a clean, lint-free cloth. See
Under
Hood Overview (page 322).
7. Replace the dipstick and remove it again to check the oil level. See
Engine Oil Dipstick
(page 324).
8. Make sure that the oil level is between
the maximum and minimum marks. If
the oil level is at the minimum mark,
add oil immediately. See
Capacities
and Specifications (page 422).
9. If the oil level is correct, replace the dipstick and make sure it is fully seated.
Note: Do not remove the dipstick when the
engine is running.
Note: If the oil level is between the
maximum and minimum marks, the oil level
is acceptable. Do not add oil.
Note: The oil consumption of new engines
reaches its normal level after approximately
3,000 mi (5,000 km)
.
