WARNING: SAFETY PRECAUTIONS MUST BE
FOLLOWED WHEN HANDLING A DEPLOYED AI
R
BAG ASSEMBLY. AFTER DEPLOYMENT, THE AIR
BAG ASSEMBLY SURFACE MAY CONTAIN A
SMALL AMOUNT OF SODIUM HYDROXIDE, A BY–
PRODUCT OF THE DEPLOYMENT REACTION,
THAT IS IRRITATING TO THE SKIN AND EYES.
MOST OF THE POWER ON THE AIR BAG
ASSEMBLY IS HARMLESS. AS A PRECAUTION,
WEAR GLOVES AND SAFETY GLASSES WHEN
HANDLING A DEPLOYED AIR BAG ASSEMBLY,
AND WASH YOUR HANDS WITH MILD SOAP AND
WATER AFTERWARDS.
WARNING: WHEN CARRYING A LIVE AIR BAG
ASSEMBLY, MAKE SURE THE BAG AND TRIM
COVER ARE POINTED AWAY FROM YOU. NEVE
R
CARRY AIR BAG ASSEMBLY BY THE WIRES O
R
CONNECTOR ON THE UNDERSIDE OF MODULE.
IN THE CASE OF AN ACCIDENTAL DEPLOYMENT,
THE BAG WILL THEN DEPLOY WITH MINIMAL
CHANCE OF INJURY. WHEN PLACING ALIVE AI
R
BAG ASSEMBLY ON A BENCH OR OTHER
SURFACE, ALWAYS FACE BAG AND RIM COVER
UP, AWAY FROM THE SURFACE. NEVER REST A
STEERING COLUMN ASSEMBLY ON THE
STEERING WHEEL WITH THE AIR BAG
ASSEMBLY FACE DOWN AND COLUMN
VERTICAL. THIS IS NECESSARY SO THAT A FREE
SPACE IS PROVIDED TO ALLOW THE AIR BAG
ASSEMBLY TO EXPAND IN THE UNLIKELY EVENT
OF ACCIDENTAL DEPLOYMENT. OTHERWISE,
PERSONAL INJURY COULD RESULT.
In the event deployment has occurred, inspect coil
assembly wire for any signs of scorching, melting o
r
any other damage due to excessive heat. If the coil
has been damaged, replace it.

Removal
1. Remove the SRS air bag assembly. (Refer to
“Driver Air Bag Assembly” in this section)

2. Remove steering wheel attachment nut.

3. Apply a setting mark across the steering wheel
and shaft so parts can be reassembled in thei
r
original position.

4. Move the tires to the straight ahead position before
removing the steering wheel. Install steering wheel
puller onto steering wheel and remove steering
wheel with 5-8521-0016-0.
5. Feed wiring through the wheel and remove wheel.
CAUTION: Never apply force to the steering wheel
in direction of the shaft by using a hammer o
r
other impact tools in an attempt to remove the
steering wheel. The steering shaft is designed as
an energy absorbing unit.

8A-132 ELECTRICAL-BODY AND CHASSIS

Wire Harness
Do not pinch the wire harnesses between the cluster and the
meter hood during the cluster installation procedure.
Wire damage will result.


AIMING OF HEADLIGHT
Check and adjust the inflation pressures, clean the headlight,
park the vehicle on a level surface and insure that vehicle is at
curb weight.


VERTICAL ADJUSTMENT
Use a screwdriver for vertical adjustment.



HORIZONTAL ADJUSTMENT
Use a screwdriver horizontal adjustment.


Installation
To install, follow the removal steps in the reverse order.
Noting the following point:
1. After installing the headlight, be sure to adjust the headligh
t
aim.

HEADLIGHT ADJUSTMENT
Preparation
Place the vehicle with 1 person in driver seat on a level surface
and check to see if the inflation pressure of the tires is correct,
the lenses are clean, the battery is sufficiently charged, and
adjust to place vehicle by using the screen.
1. Set a vertical screen on a level surface.
2. Toward the screen
1from the bulb center mark of the
headlight, extend parallel lines to the floor. Mark point
A
and B on the screen at the intersection of parallel line and
the screen.
3. Draw vertical lines through point
A and B on the screen.

6E–402 4JA1/4JH1 ENGINE DRIVEABILITY AND EMISSIONS
POOR FUEL ECONOMY SYMPTOM
DEFINITIONS: Fuel economy, as measured by an actual road test, is noticeably lower than expected. Also, economy
is noticeably lower than it was on this vehicle at one time, as previously shown by an actual road test. (Larger than
standard tires will cause odometer readings to be incorrect, and that may cause fuel economy to appear poor when it
is actually normal.)
