WARNING
∙ Never allow anyone to ride in thecargo area or on the rear seat when it
is in the fold-down position. Use of
these areas by passengers without
proper restraints could result in seri-
ous injury or death in an accident or
sudden stop.
∙ Properly secure all cargo with ropes or straps to help prevent it from sliding
or shif ting. Do not place cargo higher
than the seatbacks. In a sudden stop
or collision, unsecured cargo could
cause personal injury.
∙ When returning the seatbacks to the upright position, be certain they are
completely secured in the latched po-
sition. If they are not completely se-
cured, passengers may be injured in
an accident or sudden stop.
∙ Closely supervise children when they are around cars to prevent them from
playing and becoming locked in the
trunk where they could be seriously
injured. Keep the car locked, with the
rear seatback and trunk lid securely
latched when not in use, and prevent
children’s access to car keys.
OPENER OPERATION
The fuel-filler door release is located below
the instrument panel. To open the fuel-filler
door, pull the release. To lock, close the fuel-
filler door securely.
FUEL-FILLER CAP
WARNING
∙ Gasoline is extremely flammable andhighly explosive under certain condi-
tions. You could be burned or seri-
ously injured if it is misused or mis-
handled. Always stop the engine and
do not smoke or allow open flames or
sparks near the vehicle when
refueling.
∙ Do not attempt to top off the fuel tank af ter the fuel pump nozzle shuts off
automatically. Continued refueling
may cause fuel overflow, resulting in
fuel spray and possibly a fire.
∙ Use only an original equipment type fuel-filler cap as a replacement. It has
a built-in safety valve needed for
proper operation of the fuel system
and emission control system. An in-
correct cap can result in a serious mal-
function and possible injury. It could
also cause the
Malfunction Indi-
cator Light (MIL) to come on.
∙ Never pour fuel into the throttle body to attempt to start your vehicle.

Pre-driving checks and adjustments3-25

WARNING
∙ Do not leave children or adults whowould normally require the assis-
tance of others alone in your vehicle.
Pets should also not be lef t alone.
They could accidentally injure them-
selves or others through inadvertent
operation of the vehicle. Also, on hot,
sunny days, temperatures in a closed
vehicle could quickly become high
enough to cause severe or possibly
fatal injuries to people or animals.
∙ Closely supervise children when they are around cars to prevent them from
playing and becoming locked in the
trunk where they could be seriously
injured. Keep the car locked, with the
rear seatback and trunk lid securely
latched when not in use, and prevent
children’s access to car keys.
EXHAUST GAS (carbon monoxide)
WARNING
∙ Do not breathe exhaust gases; theycontain colorless and odorless carbon
monoxide. Carbon monoxide is dan-
gerous. It can cause unconsciousness
or death. ∙ If you suspect that exhaust fumes are
entering the vehicle, drive with all
windows fully open, and have the ve-
hicle inspected immediately.
∙ Do not run the engine in closed spaces such as a garage.
∙ Do not park the vehicle with the en- gine running for any extended length
of time.
∙ Keep the rear vent windows, lif tgates, doors and trunk lids (if so equipped)
closed while driving, otherwise ex-
haust gases could be drawn into the
passenger compartment. If you must
drive with one of these open, follow
these precautions:
1. Open all the windows.
2. Set the
air recirculation but-
ton to off and the fan control dial to
high to circulate the air.
∙ If electrical wiring or other cable con- nections must pass to a trailer
through the seal on the trunk lid or the
body, follow the manufacturer’s rec-
ommendation to prevent carbon
monoxide entry into the vehicle. ∙ The exhaust system and body should
be inspected by a qualified mechanic
whenever:
a. The vehicle is raised for service.
b. You suspect that exhaust fumes are entering into the passenger
compartment.
c. You notice a change in the sound of the exhaust system.
d. You have had an accident involving damage to the exhaust system,
underbody, or rear of the vehicle.
THREE-WAY CATALYST
The three-way catalyst is an emission con-
trol device installed in the exhaust system.
Exhaust gases in the three-way catalyst
are burned at high temperatures to help
reduce pollutants.
WARNING
∙ The exhaust gas and the exhaust sys-tem are very hot. Keep people, ani-
mals or flammable materials away
from the exhaust system
components.
PRECAUTIONS WHEN STARTING AND
DRIVING
5-4Starting and driving

CAUTION
Be careful not to burn yourself, as the
engine oil is hot.
WARNING
∙ Prolonged and repeated contact withused engine oil may cause skin
cancer.
∙ Try to avoid direct skin contact with used oil. If skin contact is made, wash
thoroughly with soap or hand cleaner
as soon as possible.
∙ Keep used engine oil out of reach of children.
4. Loosen the oil filter with an oil filter wrench by turning it counterclockwise.
Remove the oil filter by turning it by
hand.
5. Wipe the engine oil filter mounting sur- face with a clean rag.
CAUTION
Be sure to remove any old gasket mate-
rial remaining on the sealing surface of
the engine. Failure to do so could lead to
an oil leak and engine damage. ∙ The dipstick must be inserted in place
to prevent oil spillage from the dip-
stick hole when filling the engine with
oil.
6. Coat the gasket on the new filter with clean engine oil.
7. Screw in the oil filter clockwise until a slight resistance is felt, then tighten ad-
ditionally more than 2/3 turn.
Oil filter tightening torque: 11 to 15 f t-lb (14.7 to 20.6 N·m)
8. Clean and re-install the drain plug with a new washer. Securely tighten the
drain plug with a wrench. Do not use
excessive force.
Drain plug tightening torque: 22 to 29 f t-lb (29.4 to 39.2 N·m)
9. Refill the engine with the recom- mended oil through the oil filler open-
ing, and install the oil filler cap securely.
For additional information about drain and
refill capacity, refer to “Recommended
fluids/lubricants and capacities” in the
“Technical and consumer information” sec-
tion of this manual. The drain and refill ca-
pacity depends on the oil temperature and
drain time. Use these specifications for ref- erence only. Always use the dipstick to de-
termine the proper amount of oil in the
engine.
10. Start the engine and check for leakage
around the drain plug and the oil filter.
Correct as required. Turn the engine off
and wait more than 15 minutes. Check
the oil level with the dipstick. Add en-
gine oil if necessary.
Af ter the operation
1. Reinstall undercover in reverse order ofremoval.
2. Lower the vehicle carefully to the ground.
3. Reset the oil control system (if so equipped) and oil and filter mainte-
nance reminder. For additional infor-
mation, refer to "Vehicle information
