Checking Things
Under the Hood
{CAUTION
An electric fan under the hood
can start up and injure you even
when the engine is not running.
Keep hands, clothing, and tools
away from any underhood
electric fan.
{CAUTION
Things that burn can get on hot
engine parts and start a re.
These include liquids like fuel, oil,
coolant, brake uid, windshield
washer and other uids, and
plastic or rubber. You or others
could be burned. Be careful not to
drop or spill things that will burn
onto a hot engine.
Hood Release
To open the hood, do the following:
1. Pull the hood release handle with
this symbol on it. It is located
under the instrument panel
on the driver’s side of the vehicle.
2. At the front of the vehicle, pull up
on the center of the hood, and
push the secondary hood release
to the right.
3. After you have partially lifted the
hood, gas struts will automatically
take over to lift and hold the
hood in the fully open position.Before closing the hood, be sure all
ller caps are on properly.
Pull the hood down to close. Lower
the hood until the lifting pressure of
the strut is reduced. Then allow the
hood to fall and latch into place
under its own weight. Check to make
sure the hood is closed. If the hood
does not fully latch, gently push the
hood down at the front and center
of the hood until it is completely
latched.

Engine Oil
Checking Engine Oil
It is a good idea to check the
engine oil every time you get fuel.
In order to get an accurate reading,
the oil must be warm and the
vehicle must be on level ground.
The engine oil dipstick handle
is a yellow loop. SeeEngine
Compartment Overview on
page 5-10for the location of
the engine oil dipstick.
1. Turn off the engine and give the
oil several minutes to drain back
into the oil pan. If you do not
do this, the oil dipstick might
not show the actual level.2. Pull out the dipstick and clean
it with a paper towel or cloth,
then push it back in all the way.
Remove it again, keeping the
tip down, and check the level.
When to Add Engine Oil
If the oil is below the cross-hatched
area at the tip of the dipstick,
add at least one quart/liter of the
recommended oil. This section
explains what kind of oil to use.
For engine oil crankcase capacity,
seeCapacities and Specifications
on page 5-96.
Notice:Do not add too much oil.
If the engine has so much oil
that the oil level gets above the
cross-hatched area that shows
the proper operating range,
the engine could be damaged.
Service and Appearance Care 5-11

Checking Coolant
The vehicle must be on a level
surface when checking the coolant
level.
Check to see if coolant is visible in
the coolant recovery tank. If the
coolant inside the coolant recovery
tank is boiling, do not do anything
else until it cools down. If coolant is
visible but the coolant level is not
at or above the FULL COLD
mark, add a 50/50 mixture of clean,
drinkable water and DEX-COOL
coolant at the coolant recovery tank,
but be sure the cooling system is
cool before this is done. SeeEngine
Coolant on page 5-17for more
information.The coolant recovery tank cap has
this symbol on it.
When the engine is cold, the
coolant level should be at or above
the FULL COLD line marked on
the recovery tank.
When the engine is hot, the level
could be higher than the FULL
COLD line. If the coolant is below
the FULL COLD line when the
engine is hot, there could be a
leak in the cooling system.
If the coolant is low, add the
coolant or take the vehicle to a
dealer/retailer for service.
How to Add Coolant to the
Recovery Tank
{CAUTION
You can be burned if you spill
coolant on hot engine parts.
Coolant contains ethylene glycol
and it will burn if the engine parts
are hot enough. Do not spill
coolant on a hot engine.
Notice:This vehicle has a
specic coolant ll procedure.
Failure to follow this procedure
could cause the engine to
overheat and be severely
damaged.
If coolant is needed, add the proper
DEX-COOL
®coolant mixture at
the coolant recovery tank.

5-96 Service and Appearance Care

(e)Make sure the safety belt
reminder light and safety belt
assemblies 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 see
Checking the Restraint Systems on
page 1-61.
(f)Lubricate all key lock cylinders,
hood latch assemblies, secondary
latches, pivots, spring anchor and
release pawl, hood and door hinges,
rear folding seats, and liftgate
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.
(g)A fluid loss in any vehicle
system could indicate a problem.
Have the system inspected
and repaired and the fluid level
checked. Add fluid if needed.(h)Change automatic transmission
fluid if the vehicle is mainly
driven under one or more of these
conditions:
In heavy city traffic where the
outside temperature regularly
reaches 90°F (32°C) or higher.
In hilly or mountainous terrain.
When doing frequent trailer
towing.
Uses such as found in taxi,
police, or delivery service.
(i)Drain, flush, and refill cooling
system. This service can be
complex; you should have your
dealer/retailer perform this service.
See Engine Coolant on page 5-17 for
what to use. Inspect hoses. Clean
radiator, condenser, pressure cap,
and filler neck. Pressure test the
cooling system and pressure cap.
(j)Check system for interference or
binding and for damaged or missing
parts. Replace parts as needed.
Replace any components that havehigh effort or excessive wear. Do not
lubricate accelerator or cruise control
cables.
(k)Visually inspect belt for fraying,
excessive cracks, or obvious
damage. Replace belt if necessary.
(l)If driving regularly under dusty
conditions, inspect the filter at each
engine oil change.
(m)Change transfer case fluid if the
vehicle is mainly driven under
one or more of these conditions:
In heavy city traffic where
the outside temperature regularly
reaches 90°F (32°C) or higher.
In hilly or mountainous terrain.
When doing frequent trailer
towing.
Uses such as found in taxi,
police, or delivery service.
