MANUAL HEATING AND AIR CONDITIONING SYSTEM
(IF EQUIPPED)
1.Fan speed adjustment:Controls
the volume of air circulated in the
vehicle.
2.Temperature selection:
Controls the temperature of the
airflow in the vehicle.
3.Air flow selections:Controls the direction of the airflow in the
vehicle. See the following for a brief description on each control.
MAX A/C:Uses recirculated air to cool the vehicle. Air flows from the
instrument panel vents only. This mode will help prevent unpleasant
odors from entering the vehicle.
NORM A/C:Uses outside air to cool the vehicle. Air flows from the
instrument panel vents only.
VENT: Distributes outside air through the instrument panel vents.
OFF: Outside air is shut out and the fan will not operate.
FLOOR: Distributes outside air through the floor vents.
MIX: Distributes outside air through the windshield defroster vents, floor
vents and side window demisters.
:Distributes outside air through the windshield defroster vents and
the side window demisters.
Operating tips
•To reduce fog build up on the windshield during humid weather, place
the air flow selector in the
position.
•To reduce humidity build up inside the vehicle: do not drive with the
air flow selector in the OFF or MAX A/C position.
•Under normal weather conditions, do not leave the air flow selector in
MAX A/C or OFF when the vehicle is parked. This allows the vehicle
to“breathe”using the outside air inlet vents.
•Do not put objects under the front seats that will interfere with the
airflow to the back seats.
•Remove any snow, ice or leaves from the air intake area at the base of
the windshield.

•Is the shoulder belt centered on the shoulder and chest?
•Can the child stay seated like this for the whole trip?
Types of booster seats
There are two types of belt-positioning booster seats:
•Those that are backless.
If your backless booster seat has a
removable shield, remove the
shield and use the lap/shoulder
belt. If a seating position has a
low seat back and no head
restraint, a backless booster seat
may place your child’s head (top
of ear level) above the top of the
seat. In this case, move the
backless booster to another
seating position with a higher seat back and lap/shoulder belts.
•Those with a high back.
If, with a backless booster seat,
you cannot find a seating position
that adequately supports your
child’s head, a high back booster
seat would be a better choice.
Both can be used in any vehicle in a seating position equipped with
lap/shoulder belts if your child is over 40 lbs.
The shoulder belt should cross the chest, resting snugly on the center of
the shoulder. The lap belt should rest low and snug across the hips,
never up high across the stomach.
If the booster seat slides on the vehicle seat, placing a rubberized mesh
sold as shelf or carpet liner under the booster seat may improve this
condition.

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
two through nine.
Check to make sure the child seat is properly secured before each use.
Attaching child safety seats with tether straps
Most new forward-facing child safety seats include a tether strap which
goes over the back of the seat and hooks to an anchoring point. Tether
straps are available as an accessory for many older safety seats. Contact
the manufacturer of your child seat for information about ordering a
tether strap.
The rear seats of your vehicle are equipped with built-in tether strap
anchors located behind the seats as described below.
The tether anchors in your vehicle are located under a cover marked
with the tether anchor symbol (shown with title).
The tether strap anchors in your
vehicle are in the following positions
(shown from top view):
Attach the tether strap only to the appropriate tether anchor as
shown. The tether strap may not work properly if attached
somewhere other than the correct tether anchor.
1. Position the child safety seat on the seat cushion.

2. If the engine oil level is not within the normal operating range, add
only certified engine oil of the recommended viscosity. Remove the
engine oil filler cap and use a funnel to pour the engine oil into the
opening.
3. Recheck the engine oil level. Make sure the oil level is not above the
normal operating range on the engine oil level indicator (dipstick).
4. Install the indicator and ensure it is fully seated.
5. Fully install the engine oil filler cap by turning the filler cap clockwise
until three clicks can be heard.
To avoid possible oil loss, DO NOT operate the vehicle with the
engine oil level indicator and/or the engine oil filler cap removed.
