Seats (cont'd)
Head Restraints
The head restraints are designed to help reduce injuries due to whiplash. They are located at the top of each front seat-back and
have several height positions. They can be adjusted by pulling up to
the recommended position. To lower them, slide the button next to
the restraint's height bar, while pushing the restraint down.
Adjust so the top of the restraint is approximately level with the
tops of your ears. That relative position may reduce injury due to whiplash in an accident.If a head restraint must be removed (for cleaning, fabric repair, etc.)pull the restraint up to its highest position, then slide the button
while pulling the restraint out.
To reinstall, reverse the above procedure.

Spark Plug Replacement

Replace plugs one at a time, so you don't get the wires mixed up. 1. Clean any dirt from around the spark plug base.
2. Disconnect the spark plug cap, then remove and discard the old
plug.

3. Check the gap of the new spark plugs before installation.
Plug gap should be:

1.1 mm (0.04 in)

4. Thread the new spark plug in by hand to prevent cross-threading.
5. After the plug seats against the cylinder head, tighten 1/2 turn with a spark plug wrench to compress the washer.
6. Reinstall the spark plug cap.
CAUTION:
The spark plugs must be securely tightened, but not overtightened.A plug that's too loose can get very hot and possibly damage the
engine; one that's too tight could damage the threads in thecylinder head.
