Service Notice

I

When removing or installing various parts, place a cloth or padding onto the vehicle body to prevent
scratches.

I

Handle trim, molding, instruments, grille, etc. carefully during removing or installing. Be careful not to soil
or damage them.

I

Apply sealing compound where necessary when installing parts.

I

When applying sealing compound, be careful that the sealing compound does not protrude from parts.

I

When replacing any metal parts (for example body outer panel, members, etc.), be sure to take rust pre-
vention measures.

Supplemental Restraint System (SRS) “AIR
BAG” and “SEAT BELT PRE-TENSIONER”

The Supplemental Restraint System such as “AIR BAG” and “SEAT BELT PRE-TENSIONER” used along with
a seat belt, helps to reduce the risk or severity of injury to the driver and front passenger for certain types of
collision. The SRS system composition which is available to INFINITI Q45 is as follows:

I

For a frontal collision
The Supplemental Restraint System consists of driver air bag module (located in the center of the steer-
ing wheel), front passenger air bag module (located on the instrument panel on passenger side), seat belt
pre-tensioners, a diagnosis sensor unit, warning lamp, wiring harness and spiral cable.

I

For a side collision
The Supplemental Restraint System consists of front side air bag module (located in the outer side of front
seat), satellite sensor, diagnosis sensor unit (one of components of air bags for a frontal collision), wiring
harness, warning lamp (one of components of air bags for a frontal collision).

Information necessary to service the system safely is included in the RS section of this Service Manual.

WARNING:

I

To avoid rendering the SRS inoperative, which could increase the risk of personal injury or death
in the event of a collision which would result in air bag inflation, all maintenance should be per-
formed by an authorized INFINITI dealer.

I

Improper maintenance, including incorrect removal and installation of the SRS, can lead to per-
sonal injury caused by intentional activation of the system. For removal of Spiral Cable and Air Bag
Module, see the RS section.

I

Do not use electrical test equipment on any circuit related to the SRS unless instructed to in this
Service Manual. Spiral cable and wiring harnesses (except satellite sensor and side air bag mod-
ule) covered with yellow insulation tape either just before the harness connectors or for the com-
plete harness are related to the SRS.

CUSTOMER INTERVIEW

Interview the customer, if possible, to determine the conditions that exist when the noise occurs. Use the
Diagnostic Worksheet during the interview to document the facts and conditions when the noise occurs and
any customer’s comments; refer to BT-8. This information is necessary to duplicate the conditions that exist
when the noise occurs.

I

The customer may not be able to provide a detailed description or the location of the noise. Attempt to
obtain all the facts and conditions that exist when the noise occurs (or does not occur).

I

If there is more than one noise in the vehicle, be sure to diagnose and repair the noise that the customer
is concerned about. This can be accomplished by test driving the vehicle with the customer.

I

After identifying the type of noise, isolate the noise in terms of its characteristics. The noise characteris-
tics are provided so the customer, service adviser and technician are all speaking the same language when
defining the noise.

I

Squeak — (Like tennis shoes on a clean floor)
Squeak characteristics include the light contact/fast movement/brought on by road conditions/hard sur-
faces = higher pitch noise/softer surfaces = lower pitch noises/edge to surface = chirping

I

Creak — (Like walking on an old wooden floor)
Creak characteristics include firm contact/slow movement/twisting with a rotational movement/pitch depen-
dent on materials/often brought on by activity.

I

Rattle — (Like shaking a baby rattle)
Rattle characteristics include the fast repeated contact/vibration or similar movement/loose parts/missing
clip or fastener/incorrect clearance.

I

Knock — (Like a knock on a door)
Knock characteristics include hollow sounding/sometimes repeating/often brought on by driver action.

I

Tick — (Like a clock second hand)
Tick characteristics include gentle contacting of light materials/loose components/can be caused by driver
action or road conditions.

I

Thump — (Heavy, muffled knock noise)
Thump characteristics include softer knock/dead sound often brought on by activity.

I

Buzz — (Like a bumble bee)
Buzz characteristics include high frequency rattle/firm contact.

I

Often the degree of acceptable noise level will vary depending upon the person. A noise that you may judge
as acceptable may be very irritating to the customer.

I

Weather conditions, especially humidity and temperature, may have a great effect on noise level.
