SERVICE PRECAUTIONS
The DERM can maintain sufficient volt age to cause a deployment for up to 10
minutes after the ignition switch is tur ned OFF or the battery is disconnected.
Always disable the system when perfo rming service procedures ON OR NEAR
the system and it's components.
CAUTION - The disarming and arming procedures must be followed in the
order listed to temporarily disable the SI R system. Failure to do so could result
in possible air bag deployment, pers onal injury or otherwise unneeded SIR
system repairs.
DISARMING THE SYSTEM
1. Turn the steering wheel so that t he vehicle's wheels are pointing straight
ahead.
2. Turn the ignition switch to the LOCK position.
3. Remove the SIR or AIR BAG fuse from the fuse panel.
4. Remove the left side trim panel, t hen remove the Connector Position
Assurance (CPA) device and disconnec t the yellow two-way SIR harness
connector at the base of the steering column.
5. On vehicles with passenger side air bags, remove the glove box door
then disconnect the yellow two-way c onnector located near the yellow
24-way DERM harness connector.
With the fuse removed and the ignition sw itch ON, the air bag warning lamp will
be on. This is normal and does not indicate a SIR system malfunction.

ENGINE OIL AND FILTER CHANGE
Under normal operating conditions, the oi
l is to be changed every 7,500 miles
(12,000km) or 12 months, whichever occurs first.
Although the manufacturer recommends changing the f ilter at the first oil
change and then at every other oil c hange, (unless 12 months pass between
changes), The editors of this informat ion recommend changing the filter with
each service. It is a small price to pay for extra protection.
When driving conditions frequently include dusty or polluted areas, trailer
towing, idling for long periods of ti me, or low speed operation, or when
operating at temperatures below freezing or driving short distances (under 4
miles or 6.4km), change t he oil and filter more frequently. Under these
circumstances, oil has a greater chance of building up sludge and contaminants
which could damage your engine. If your v ehicle use fits into one or more of
these categories, (as it does for most vehicles), it is suggested that the oil and
filter be changed every 3, 000 miles (1361km) or 3 months, whichever comes
first.
The oil should be disposed of properly after it is drained from the vehicle. Store
the oil in a suitable container and take the container to an official oil recycling
station. Most gas stations or oil and lube facilities will take the used oil at little or
no expense to you.
Oil should always be changed after the engine has been running long enough to
bring it up to normal operating temperature. Hot oil will flow more easily and will
carry more contaminants than will cold oi l. The oil drain plug is located on the
bottom of the oil pan (bottom of the engi ne, underneath the car). The oil filter is
located on the left side of most engines covered by this information. To change
the oil and filter:
1. Run the engine until it reaches normal operating temperature.
2. Raise the front of the vehicle and s upport it safely using a suitable pair of
jackstands.
3. Slide a drain pan of a least 6 quar ts capacity under the oil pan. Wipe the
drain plug and surrounding area clean using an old rag.
CAUTION - The EPA warns that prolonged contact with used engine oil may
cause a number of skin disorders, incl uding cancer! You should make every
effort to minimize your exposure to used engine oil. Pr otective gloves should be
worn when changing the oil. Wash y our hands and any other exposed skin
areas as soon as possible after exposure to used engine oil. Soap and water, or
waterless hand cleaner should be used.
4. Loosen the drain plug using a ratc het, short extension and socket or a
box-wrench. Turn the plug out by hand, using a rag to shield your fingers
from the hot oil. By keeping an in ward pressure on the plug as you
unscrew it, oil won't escape past the threads and you can remove it
without being burned by hot oil.
