3. While holding the shoulder and
lap belt portions together, route the
tongue through the child seat
according to the child seat
manufacturer’s instructions. Be sure
the belt webbing is not twisted.
4. Insert the belt tongue into the
proper buckle (the buckle closest to
the direction the tongue is coming
from) for that seating position until
you hear a snap and feel the latch
engage. Make sure the tongue is
latched securely by pulling on it.
5. To put the retractor in the
automatic locking mode, grasp the
shoulder portion of the belt and pull
downward until all of the belt is
pulled out and a click is heard.
6. Allow the belt to retract. The belt will click as it retracts to indicate it
is in the automatic locking mode.

7. Pull the lap belt portion across
the child seat toward the buckle and
pull up on the shoulder belt while
pushing down with your knee on the
child seat.
8. Allow the safety belt to retract to
remove any slack in the belt.
9. Before placing the child in the
seat, forcibly move the seat forward
and back to make sure the seat is
securely held in place. To check
this, grab the seat at the belt path
and attempt to move it side to side
and forward. There should be no
more than one inch of movement for
proper installation.
10. Try to pull the belt out of the retractor to make sure the retractor is
in the automatic locking mode (you should not be able to pull more belt
out). If the retractor is not locked, unbuckle the belt and repeat Steps 2
through 9.
Check to make sure the child seat is properly secured before each use.
Installing child safety seats in the center front seating position
(if equipped)
Always transport children 12 years old and under in the rear
seats and always properly use appropriate child restraints.
It is safer to install child safety seats in seating positions that
have child seat anchors. The front seat has no tether anchor nor
does it have LATCH anchors.
1. Lengthen the lap belt. To lengthen the belt, hold the tongue so that its
bottom is perpendicular to the direction of webbing while sliding the
tongue up the webbing.

Keep batteries out of reach of children. Batteries contain sulfuric
acid. Avoid contact with skin, eyes or clothing. Shield your eyes
when working near the battery to protect against possible splashing of
acid solution. In case of acid contact with skin or eyes, flush
immediately with water for a minimum of 15 minutes and get prompt
medical attention. If acid is swallowed, call a physician immediately.
Battery posts, terminals and related accessories contain lead and
lead compounds.Wash hands after handling.
Because your vehicle’s engine is electronically controlled by a computer,
some control conditions are maintained by power from the battery. When
the battery is disconnected or a new battery is installed, the engine must
relearn its idle and fuel trim strategy for optimum driveability and
performance. To begin this process:
1. With the vehicle at a complete stop, set the parking brake.
2. Put the gearshift in P (Park), turn off all accessories and start the
engine.
3. Run the engine until it reaches normal operating temperature.
4. Allow the engine to idle for at least one minute.
5. Turn the A/C on and allow the engine to idle for at least one minute.
6. Release the parking brake. With your foot on the brake pedal and with
the A/C on, put the vehicle in D (Drive) and allow the engine to idle for
at least one minute.
7. Drive the vehicle to complete the relearning process.
•The vehicle may need to be driven 10 miles (16 km) or more to
relearn the idle and fuel trim strategy.
•If you do not allow the engine to relearn its idle trim, the idle
quality of your vehicle may be adversely affected until the idle
trim is eventually relearned.
If the battery has been disconnected or a new battery has been installed,
the clock and radio settings must be reset once the battery is
reconnected.

Refueling
Fuel vapor burns violently and a fuel fire can cause severe
injuries. To help avoid injuries to you and others:
•Read and follow all the instructions on the pump island;
•Turn off your engine when you are refueling;
•Do not smoke if you are near fuel or refueling your vehicle;
•Keep sparks, flames and smoking materials away from fuel;
•Stay outside your vehicle and do not leave the fuel pump unattended
when refueling your vehicle — this is against the law in some places;
•Keep children away from the fuel pump; never let children pump
fuel.
Use the following guidelines to avoid electrostatic charge build-up when
filling an ungrounded fuel container:
•Place approved fuel container on the ground.
•DO NOT fill a fuel container while it is in the vehicle (including the
cargo area).
•Keep the fuel pump nozzle in contact with the fuel container while
filling.
•DO NOT use a device that would hold the fuel pump handle in the fill
position.
Fuel Filler Cap
Your fuel tank filler cap has an indexed design with a 1/4 turn on/off
feature.
When fueling your vehicle:
1. Turn the engine off.
2. Carefully turn the filler cap counterclockwise 1/4 turn until it stops.
3. Pull to remove the cap from the fuel filler pipe.
4. To install the cap, align the tabs on the cap with the notches on the
filler pipe.
5. Turn the filler cap clockwise 1/4 of a turn until at least a few clicks are
heard.
If the check fuel cap lamp
or a “check fuel cap” message come on,
the fuel filler cap may not be properly installed. The lamp or message
can come on after several driving events after you’ve refueled your
vehicle.
