1. Set mirror assembly mirror glass upward.
2. Apply protective tape to mirror housing.
3. Insert a screwdriver under tab (1) and gently twist screw driver
to release mirror glass and holder from mirror bracket (2).
Remove the mirror glass and holder by hand to fully disengage
from bracket.
4. Disconnect two electrical connectors (3), (4) from mirror glass
and holder.
INSTALLATION
1. Set mirror holder bracket and mirror glass and holder in the hor-
izontal position. Ensure that the metal damper blades (1) on the
mirror glass are aligned with the ramps (2) inside the plastic mir-
ror case.
2. Connect two electrical connectors (4), (3) to the back of the mir-
ror holder.
3. Align mirror glass and holder with mirror holder bracket and
push mirror glass and holder onto mirror holder bracket.
4. Rotate mirror to ensure proper installation.

SERVICE INFORMATION
PRECAUTIONS
Precaution for Supplemental Restraint System (SRS) "AIR BAG" and "SEAT BELT
PRE-TENSIONER"
INFOID:0000000003533141
The Supplemental Restraint System such as “AIR BAG” and “SEAT BELT PRE-TENSIONER”, used along
with a front seat belt, helps to reduce the risk or severity of injury to the driver and front passenger for certain
types of collision. This system includes seat belt switch inputs and dual stage front air bag modules. The SRS
system uses the seat belt switches to determine the front air bag deployment, and may only deploy one front
air bag, depending on the severity of a collision and whether the front occupants are belted or unbelted.
Information necessary to service the system safely is included in the SRS and SB section of this Service Man-
ual.
WARNING:
• 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 must be performed by
an authorized NISSAN/INFINITI dealer.
• Improper maintenance, including incorrect removal and installation of the SRS, can lead to personal
injury caused by unintentional activation of the system. For removal of Spiral Cable and Air Bag
Module, see the SRS section.
• Do not use electrical test equipment on any circuit related to the SRS unless instructed to in this
Service Manual. SRS wiring harnesses can be identified by yellow and/or orange harnesses or har-
ness connectors.
