{CAUTION:
You can be burned if you spill coolant on hot
components in the engine compartment.
Coolant contains ethylene glycol, and it will
burn if the engine parts are hot enough. Do not
spill coolant on a hot engine or components in
the engine compartment.
When the coolant in the coolant surge tank is at the
COLD FILL mark, start your vehicle.1. You can remove the coolant surge tank pressure cap
when the cooling system, including the coolant surge
tank pressure cap and upper radiator hose, is no
longer hot. Turn the pressure cap slowly
counterclockwise about one full turn.
If you hear a hiss, wait for that to stop. A hiss
means there is still some pressure left.
2. Then keep turning the pressure cap slowly, and
remove it.
3. Fill the coolant surge tank with the proper mixture,
up to the FULL COLD mark. SeeEngine Coolant
on page 5-34
4. With the coolant surge tank pressure cap off, start
the engine and let it run until you can feel the upper
radiator hose getting hot. Watch out for the engine
cooling fan. By this time, the coolant level inside the
coolant surge tank may be lower. If the level is lower,
add more of the proper mixture to the coolant surge
tank until the level reaches the FULL COLD mark.
5. Then replace the pressure cap. Be sure the
pressure cap is hand-tight and fully seated.

(g)Make sure the safety belt reminder light and all your
belts, buckles, latch plates, retractors, and anchorages
are working properly. Look for any other loose or
damaged safety belt system parts. If you see anything
that might keep a safety belt system from doing its
job, have it repaired. Have any torn or frayed safety belts
replaced. Also look for any opened or broken airbag
coverings, and have them repaired or replaced.
The airbag system does not need regular maintenance.
(h)Lubricate all key lock cylinders, body door hinges,
hood latch assembly, secondary latch, pivots, spring
anchor, release pawl, fuel door hinge, locks, latches,
and any folding or moving seat hardware. Pickup
models: Lubricate tailgate hinges, tailgate linkage,
tailgate handle pivot points, and latch bolt. Van models:
Lubricate hood hinges and rear compartment hinges.
More frequent lubrication may be required when
exposed to a corrosive environment. Applying silicone
grease on weatherstrips with a clean cloth will make
them last longer, seal better, and not stick or squeak.
(i)Van Models: If the two chassis mounted fuel
lters have not been replaced, or if the vehicle has
been driven 20,000 miles (32 000 km) or more since the
fuel lters were last replaced, replace both fuel lters.(j)Pickup Models: This vehicle has a CHANGE FUEL
FILTER message in the Driver Information Center (DIC)
to tell you when to replace the fuel lter. See Driver
Information Center (DIC) (Pickup Models Only) on
page 3-9 for more information and how to reset the
message after the fuel lter is replaced. If the fuel lter
has not been replaced, or if the vehicle has been driven
15,000 miles (25 000 km) or more since the fuel lter was
last replaced, replace the lter and reset the message.

or looseness. Adjust or replace as required. This is a
Noise Emission Control Service. Applicable to vehicles
sold in the United States and recommended for

connections and fasteners or replace damaged parts as
necessary. This is a Noise Emission Control Service.
Applicable to vehicles sold in the United States and
recommended for vehicles sold in Canada.
