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:
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.
SeeEngine Compartment Overview on page 6-12
for 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.
6-15

Checking Coolant
The vehicle must be on a level surface when checking
the coolant level.
The coolant recovery tank
cap has this symbol on it.
It is located toward the rear of the engine compartment
on the passenger side of the vehicle. SeeEngine
Compartment Overview on page 6-12for more
information on location.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.
The vehicle must be on a level surface. When the engine
is cold, the coolant level should be at FULL COLD, or a
little higher. When the engine is warm, the level could be
above the FULL COLD level.
When the engine is cold, the coolant level should be
at least up to the FULL COLD mark. If it is not,
there could be a leak in the cooling system.
6-31

Checking Brake Fluid
Check brake fluid by looking at the brake fluid reservoir.
SeeEngine Compartment Overview on page 6-12.
The fluid level should
be above the PP mark.
If it is not, have the brake
hydraulic system checked
to see if there is a leak.
After work is done on the brake hydraulic system, make
sure the level is above the PP mark but not over the
MAX mark.
What to Add
Use only new DOT 3 brake fluid from a sealed container.
SeeRecommended Fluids and Lubricants on page 7-10.
Always clean the brake fluid reservoir cap and the
area around the cap before removing it. This helps
keep dirt from entering the reservoir.
{WARNING:
With the wrong kind of fluid in the brake hydraulic
system, the brakes might not work well. This could
cause a crash. Always use the proper brake fluid.
Notice:
Using the wrong uid can badly damage brake
hydraulic system parts. For example, just a
few drops of mineral-based oil, such as engine
oil, in the brake hydraulic system can damage
brake hydraulic system parts so badly that they
will have to be replaced. Do not let someone
put in the wrong kind of uid.
If brake uid is spilled on the vehicle’s painted
surfaces, the paint nish can be damaged.
Be careful not to spill brake uid on the vehicle.
If you do, wash it off immediately. SeeWashing
Your Vehicle on page 6-106.
