Filling a Portable Fuel Container
{WARNING:
Never fill a portable fuel container while it is in the
vehicle. Static electricity discharge from the
container can ignite the fuel vapor. You can be
badly burned and the vehicle damaged if this
occurs. To help avoid injury to you and others:
•Dispense fuel only into approved containers.
•Do not fill a container while it is inside a
vehicle, in a vehicle’s trunk, pickup bed, or on
any surface other than the ground.
•Bring the fill nozzle in contact with the inside
of the fill opening before operating the nozzle.
Contact should be maintained until the filling
is complete.
•Do not smoke while pumping fuel.
•Do not use a cellular phone while
pumping fuel.
Checking Things Under
the Hood
{WARNING:
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.
{WARNING:
Things that burn can get on hot engine parts and
start a fire. These include liquids like fuel, oil,
coolant, brake fluid, windshield washer and other
fluids, 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.

Checking Engine Oil
It is a good idea to check the engine oil level at each
fuel fill. 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. See
Engine Compartment Overview on page 6-14for
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 this is not done, 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.

•Protects against rust and corrosion.
•Will not damage aluminum parts.
•Helps keep the proper engine temperature.
Notice:If an improper coolant mixture is used, the
engine could overheat and be badly damaged.
The repair cost would not be covered by the vehicle
warranty. Too much water in the mixture can
freeze and crack the engine, radiator, heater core,
and other parts.
Notice:If extra inhibitors and/or additives are used
in the vehicle’s cooling system, the vehicle could
be damaged. Use only the proper mixture of
the engine coolant listed in this manual for the
cooling system. SeeRecommended Fluids and
Lubricants on page 7-10for more information.
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 atthe coolant recovery tank, but be sure the cooling
system is cool before this is done. SeeEngine Coolant
on page 6-25for more information.
The coolant level should be at or above the FULL
COLD mark on the coolant surge tank. If it is not, you
may have a leak at the pressure cap or in the radiator
hoses, heater hoses, radiator, water pump, or
somewhere else in the cooling system.
How to Add Coolant to the
Recovery Tank
{WARNING:
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 speci c 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.

•Fluids visual leak check (or every 12 months,
whichever occurs first). A leak in any system must
be repaired and the fluid level checked.
•Engine air cleaner filter inspection (vehicles driven
in dusty conditions only). SeeEngine Air
Cleaner/Filter on page 6-21.
•Brake system inspection (or every 12 months,
whichever occurs first).
MaintenanceII
•Perform all services described in MaintenanceI.
•Steering and suspension inspection. Visual
inspection for damaged, loose, or missing parts or
signs of wear.
•Engine cooling system inspection. Visual inspection
of hoses, pipes, fittings, and clamps and
replacement, if needed.
•Windshield wiper blade inspection for wear,
cracking, or contamination and windshield and wiper
blade cleaning, if contaminated. SeeWindshield
and Wiper Blades on page 6-93. Worn or damaged
wiper blade replacement. SeeWindshield Wiper
Blade Replacement on page 6-44.
•Body hinges and latches, key lock cylinders, and
rear compartment and hood hinges and latches
lubrication. SeeRecommended Fluids and
Lubricants on page 7-10. More frequent lubrication
may be required when vehicle is exposed to a
corrosive environment. Applying silicone grease on
weatherstrips with a clean cloth makes them last
longer, seal better, and not stick or squeak.
•Restraint system component check. SeeChecking
the Restraint Systems on page 2-75.
•Engine air cleaner filter inspection. SeeEngine Air
Cleaner/Filter on page 6-21.
•3.6L Engine Only: Automatic transmission fluid level
check and adding fluid, if needed. SeeAutomatic
Transmission Fluid on page 6-23.
Additional Required Services
At Each Fuel Stop
•
Engine oil level check. SeeEngine Oil on
page 6-17.
•Engine coolant level check. SeeEngine Coolant on
