TRUNK

Trunk noises are often caused by a loose jack or loose items put into the trunk by the owner.
In addition look for:
1.

Trunk lid dumpers out of adjustment

2.

Trunk lid striker out of adjustment 

3.

The trunk lid torsion bars knocking together

4.

A loose license plate or bracket

Most of these incidents can be repaired by adjusting, securing or insulating the item(s) or component(s) caus-
ing the noise.

SUNROOF/HEADLINING

Noises in the sunroof/headlining area can often be traced to one of the following:

1.

Sunroof lid, rail, linkage or seals making a rattle or light knocking noise

2.

Sunvisor shaft shaking in the holder

3.

Front or rear windshield touching headlining and squeaking 

Again, pressing on the components to stop the noise while duplicating the conditions can isolate most of these
incidents. Repairs usually consist of insulating with felt cloth tape.

SEATS

When isolating seat noise it's important to note the position the seat is in and the load placed on the seat when
the noise is present. These conditions should be duplicated when verifying and isolating the cause of the
noise.
Cause of seat noise include: 

1.

Headrest rods and holder 

2.

A squeak between the seat pad cushion and frame 

3.

The rear seatback lock and bracket 

These noises can be isolated by moving or pressing on the suspected components while duplicating the con-
ditions under which the noise occurs. Most of these incidents can be repaired by repositioning the component
or applying urethane tape to the contact area.

UNDERHOOD

Some interior noise may be caused by components under the hood or on the engine wall. The noise is then
transmitted into the passenger compartment.
Causes of transmitted underhood noise include:
1.

Any component mounted to the engine wall

2.

Components that pass through the engine wall

3.

Engine wall mounts and connectors

4.

Loose radiator mounting pins

5.

Hood bumpers out of adjustment 

6.

Hood striker out of adjustment

These noises can be difficult to isolate since they cannot be reached from the interior of the vehicle. The best
method is to secure, move or insulate one component at a time and test drive the vehicle. Also, engine RPM
or load can be changed to isolate the noise. Repairs can usually be made by moving, adjusting, securing, or
insulating the component causing the noise.

LONGITUDINAL AND LATERAL CLEARANCE ADJUSTMENT

1.

Remove hood lock assembly, loosen the hood hinge nuts and close the hood.

2.

Adjust the lateral and longitudinal clearance, and open the hood to tighten the hood hinge mounting bolts
to the specified torque.

3.

Install the hood lock temporarily, and align the hood striker and lock so that the centers of striker and lock
become vertical viewed from the front, by moving the hood lock laterally.

4.

Tighten hood lock mounting bolts to the specified torque.

CAUTION:

Adjust right/left Clearance between hood and each part to the following specification.

FRONT END HEIGHT ADJUSTMENT

1.

Remove the hood lock and adjust the height by rotating the bumper rubber until the hood becomes 1 to1.5
mm (0.04 to 0.059 in) lower than the fender.

2.

Temporarily tighten the hood lock, and position it by engaging it with the hood striker. Check the lock and
striker for looseness, and tighten the hood lock mounting bolts to the specified torque.

SURFACE HEIGHT ADJUSTMENT

1.

Remove hood lock, and adjust the surface height difference of hood, fender and headlamp according to
the fitting standard dimension, by rotating RH and LH bumper rubbers.

2.

Install hood lock temporarily, and move hood lock laterally until the centers of striker and lock become ver-
tical when viewed from the front.

3.

Make sure that the hood lock secondary latch is properly
engaged with the secondary striker with hood's own weight.

4.

Make sure that the hood lock primary latch is securely engaged
with the hood striker with hood's own weight by dropping hood
from approx. 200 mm(7.87in) height.

CAUTION:

Do not drop hood from a height of 300 mm (11.81 in) or
more.

5.

Move hood lockup and down until striker smoothly engages the
lock when the hood is closed.

6.

When pulling the hood opener lever gently, make sure that front
end of the hood rises by approximately 20 mm (0.79 in) and that hood striker and hood lock primary latch
is disengaged. Also make sure that hood opener returns to the original position.

7.

After adjustment, tighten lock bolts to the specified torque.
