What to Do with Used Oil
Used engine oil contains certain elements that may be
unhealthy for your skin and could even cause cancer.
Do not let used oil stay on your skin for very long. Clean
your skin and nails with soap and water, or a good
hand cleaner. Wash or properly dispose of clothing or
rags containing used engine oil. See the manufacturer’s
warnings about the use and disposal of oil products.
Used oil can be a threat to the environment. If you
change your own oil, be sure to drain all the oil from the
lter before disposal. Never dispose of oil by putting it
in the trash, pouring it on the ground, into sewers, or
into streams or bodies of water. Instead, recycle it
by taking it to a place that collects used oil. If you have
a problem properly disposing of your used oil, ask
your dealer, a service station, or a local recycling
center for help.

When to Inspect the Engine
Air Cleaner/Filter

{CAUTION:
Steam and scalding liquids from a hot cooling
system can blow out and burn you badly. They
are under pressure, and if you turn the radiator
pressure cap — even a little — they can come
out at high speed. Never turn the cap when the
cooling system, including the radiator pressure
cap, is hot. Wait for the cooling system and
radiator pressure cap to cool if you ever have
to turn the pressure cap.
How to Add Coolant to the Radiator
Notice:Your engine has a specic radiator
ll procedure. Failure to follow this procedure could
cause your engine to overheat and be severely
damaged.1. You can remove the radiator pressure cap when
the cooling system, including the radiator pressure
cap and upper radiator hose, is no longer hot.
Turn the pressure cap slowly counterclockwise until
it rst stops. Do not press down while turning the
pressure cap.
If you hear a hiss, wait for that to stop. A hiss
means there is still some pressure left.

The terminal is located
under a tethered cap at
the front of the underhood
fuse block. SeeEngine
Compartment Overview on
page 5-12for more
information on location.
Squeeze the tabs and swing the cap out of the way
to access the remote positive (+) terminal. You

instead of the positive (+) terminal on your battery.
{CAUTION:
An electric fan can start up even when the
engine is not running and can injure you.
Keep hands, clothing and tools away from
any underhood electric fan.
{CAUTION:
Using a match near a battery can cause battery
gas to explode. People have been hurt doing
this, and some have been blinded. Use a
ashlight if you need more light.
Be sure the battery has enough water. You do
not need to add water to the battery installed
in your new vehicle. But if a battery has ller
caps, be sure the right amount of uid is there.
If it is low, add water to take care of that rst.
If you do not, explosive gas could be present.
Battery uid contains acid that can burn you.
Do not get it on you. If you accidentally get it
in your eyes or on your skin, ush the place

{CAUTION:
Changing a tire can be dangerous. The vehicle
can slip off the jack and roll over or fall on you
or other people. You and they could be badly
injured or even killed. Find a level place to
change your tire. To help prevent the vehicle
from moving:
1. Set the parking brake rmly.
2. Put the shift lever in PARK (P).
3. Turn off the engine and do not restart
while the vehicle is raised.
4. Do not allow passengers to remain in
the vehicle.
To be even more certain the vehicle will not
move, you should put blocks at the front and
rear of the tire farthest away from the one
being changed. That would be the tire, on the
other side, at the opposite end of the vehicle.When your vehicle has a at tire, use the following
example as a guide to assist you in the placement of
wheel blocks.
The following information will tell you next how to use
the jack and change a tire.

2. Turn the folding wrench counterclockwise to lower
the compact spare tire to the ground. Continue to
turn the wrench so the compact spare tire can
be pulled out from under the vehicle.
3. Tilt the retainer at the end of the cable to remove
the compact spare tire, so it can be pulled up
through the wheel opening.After removing the compact spare tire, turn the
wrench clockwise to raise the cable back up. You
can not store a full-size tire under the vehicle.
It should be stowed inside the vehicle by the cable
provided. SeeStoring a Flat or Spare Tire and
Tools on page 5-74for more information.
4. Remove the compact spare tire from the cable.
If the compact spare tire will not lower, check under
the vehicle to see if the tire is hanging loose and
the cable end and spring under the wheel plate are
missing. If so, the secondary latch system is engaged.
SeeSecondary Latch System on page 5-72.
To continue changing the at tire, seeRemoving the
Flat Tire and Installing the Spare Tire on page 5-67.

Removing the Flat Tire and
Installing the Spare Tire
If the wheel has a center cap, use the handle of the
folding wrench to pry it off. Then, with the other end of
the folding wrench, loosen the nuts.
If your vehicle has the plastic bolt-on wheel covers,
loosen the bolts completely using the folding wrench,
and remove the wheel cover.
Once the center cap and/or wheel cover are removed,
use the following steps to remove the at tire and
install the spare tire.1. Loosen the wheel
nuts — but do not
remove them — using
the folding wrench.
Turn the handle
counterclockwise about
180 degrees, then ip
the handle back to
the starting position.
This avoids taking the
wrench off the lug nut
for each turn.
For wheels equipped with a wheel lock key, use
the wheel lock key between the lock nut and folding
wrench. The key is supplied in the front passenger
door pocket.
Notice:If your vehicle has wheel locks and you
use an impact wrench to remove the wheel nuts,
you could damage the lock nut or wheel lock key.
Do not use an impact wrench to remove the
wheel nuts if your vehicle has wheel locks.
Notice:If you use a jack to raise the vehicle without
positioning it correctly, you could damage your
vehicle. When raising your vehicle on a jack, avoid
contact with the rear axle control arms.
