When you decide it’s safe to lift the hood, here’s what
you’ll see:
A. Radiator pressure cap
B. Coolant recovery tank
C. Engine fan(s)
If the coolant inside the coolant recovery tank is boiling,
don’t do anything else until it cools down.
The coolant level should be at or above the FULL
COLD mark.

Recovery Tank
If you haven’t found a problem yet, but the coolant level
isn’t at the
FULL COLD mark, add a 50/50 mixture of
dean water (preferably distilled) and DEX-COOL@
(silicate-free) antifreeze at the coolant recovery tank. (See
“Engine Coolant” in the Index for more information.)
Adding only plain water to your cooling system
can be dangerous. Plain water, or some other
liquid like alcohol, can boil before the proper
coolant mix will. Your vehicle’s coolant warning
system is set for the proper coolant mix.
CAUTION: (Continued) With plain water
or the wrong mix, your engine
could get too hot but you wouldn’t get the
overheat warning. Your engine could catch fire
and you or others could be burned. Use
a 50/50
mix of clean water and DEX-COOL@ coolant.
I NOTICE:
In cold weather, water can freeze and crack the
engine, radiator, heater core and other parts.
Use the recommended coolant and the proper
coolant mix.

Rust or dirt on the wheel, or on the parts to
which it is fastened, can make the wheel nuts
become loose after
a time. The wheel could come
off and cause an accident. When you change
a
wheel, remove any rust or dirt from the places
where the wheel attaches to the vehicle. In an
emergency, you can use a cloth or
a paper towel
to do this; but be sure to use
a scraper or wire
brush later, if you need to, to get all the rust or
dirt off.
A CAUTION:
Never use oil or grease on studs or nuts. If you
do, the nuts might come loose. Your wheel could
fall off, causing a serious accident.
8. Replace the wheel nuts
with the rounded end
of
the nuts toward the
wheel. Tighten each
wheel nut by hand until
the wheel is held against
the hub.
9. Lower the vehicle by rotating the jack handle
counterclockwise. Lower the jack completely.

If you plan on driving in another country outside the
United States
or Canada, the proper fuel may be hard to
find. Never use leaded gasoline or any other fuel not
recommended in the previous text on fuel. Costly repairs
caused by use of improper fuel wouldn’t be covered by
your warranty.
To check on fuel availability, ask an auto club, or
contact a major oil company that does business in the
country where you’ll be driving.
You can also write us at the following address for
advice. Just tell us where you’re going and give your
Vehicle Identification Number (VIN).

underhood electric fan.
I A CAUTION:
i
Things that burn can get on hot engine parts and
start
a fire. These include liquids like gasoline,
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.
Before closing the hood, be sure all the filler caps are
on properly.
Then
lift the hood to relieve pressure on the hood prop.
Remove the hood prop from the slot in the hood and

Engine Oil (Gasoline Engine)
If your vehicle has a diesel engine, see “Engine Oil
(Diesel Engine)” in the Diesel Engine Supplement.
It’s a good idea to check your 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.
Turn off the engine and give
the oil a few minutes to
drain back into the oil
pan.
If you don’t, the oil
dipstick might not show
the actual level.
