DESCRIPTION AND OPERATION

INSTRUMENT PANEL SYSTEM

DESCRIPTION

The instrument panel serves as the command cen-

ter of the vehicle, which necessarily makes it a very

complex unit. The instrument panel is designed to

house the controls and monitors for standard and

optional powertrains, climate control systems, audio

systems, lighting systems, safety systems and many

other comfort or convenience items. The instrument

panel is also designed so that all of the various con-

trols can be safely reached and the monitors can be

easily viewed by the vehicle operator when driving,

while still allowing relative ease of access to each of

these items for service. See the owner’s manual in

the vehicle glove box for more information on the fea-

tures, use and operation of all of the instrument

panel components and systems.

This group is responsible for covering service infor-

mation for the vehicle instrument panel systems.

However, complete service information coverage for

all of the systems and components housed in the

instrument panel in a single section of the service

manual would not be practical. Therefore, the service

information for any component will be found in the

group designated to cover the vehicle system that the

component belongs to, even though the component is

mounted on or in the instrument panel. If you cannot

locate a listing for the component or system you are

servicing in the table of contents for this group, or if

you are uncertain as to which vehicle system a com-

ponent belongs to, it is suggested that you refer to

the alphabetical Component and System Index

found at the back of this service manual.

NOTE: This group covers both Left-Hand Drive

(LHD) and Right-Hand Drive (RHD) versions of this

model. Whenever required and feasible, the RHD

versions of affected vehicle components have been

constructed as mirror-image of the LHD versions.

While most of the illustrations used in this group

represent only the LHD version, the diagnostic and

service

procedures

outlined

can

generally

applied to either version. Exceptions to this rule

have been clearly identified as LHD or RHD, if a

special illustration or procedure is required.

INSTRUMENT PANEL

DESCRIPTION

This instrument panel uses a full-width structural

plastic foundation as its primary support. When the

two primary molded plastic components of this struc-

ture are vibration welded together they provide supe-

rior instrument panel stiffness and integrity to help
