trol switch when operating switch.
Tilt & telescopic switch Tilt switch
 Tilt switch is equipped to steering column.
 The operation signal is input to automatic drive positioner control
unit when tilt switch is operated.
Telescopic switch  Telescopic switch is equipped to steering column.
 The operation signal is input to automatic drive positioner control
unit when telescopic switch is operated.
Seat memory switch Set switch
It is used for registration and setting change of driving position and
Intelligent Key interlock function.
Seat memory switch  The maximum 2 driving positions can be registered by memory
switch 1 to 2.
 Driving position is set to the registered driving position when memory switch is pressed while operation conditions are satis-
fied.
Seat memory indicator Memory indicator indicates the status of auto driving position sys-
tem by turning ON or blinking.
Power seat switch Sliding switch
 Sliding switch is equipped to power seat switch on seat cushion
side surface.
 The operation signal is input to driver seat control unit when slid- ing switch is operated.
Reclining switch  The operation signal is input to driver seat control unit when re-
clining switch is operated.
 The operation signal is input to driver seat control unit when re-
clining switch is operated.
Lifting switch (front)  Lifting switch (front) is equipped to power seat switch on seat
cushion side surface.
 The operation signal is input to driver seat control unit when lift-
ing switch (front) is operated.
Lifting switch (rear)  Lifting switch (rear) is equipped to power seat switch on seat
cushion side surface.
 The operation signal is input to driver seat control unit when lift-
ing switch (rear) is operated.

REMOVAL
1. Remove front pillar garnish (LH and RH). Refer to INT-14, "Removal and Installation".
2. Remove partially headlining (front edge). Refer to INT-29, "
Removal and Installation".
3. Disconnect inside mirror harness connector.
4. Remove rain sensor cover and then disconnect rain sensor harness connector. Refer to WW-72,
"Removal and Installation".
5. Remove drip molding. Refer to EXT-43, "
Removal and Installation".
6. Remove windshield molding upper using pliers. Refer to GW-11, "
Exploded View".
7. Remove front wiper arm (LH and RH). Refer to WW-66, "
Removal and Installation".
8. Remove cowl top cover. Refer to EXT-21, "
Removal and Installation".
9. Remove front fender cover (LH and RH). Refer to EXT-21, "
Exploded View".
10. Disconnect wiper deicer harness connector (with wiper deicer).
11. Remove front pillar finisher (LH and RH). Refer to EXT-40, "
Removal and Installation".
12. Apply protective tape around the windshield glas s to protect the painted surface from damage.
13. Remove glass using piano wire or power cutting tool (A) and an inflatable pump bag (B).
NOTE:
Mark the body and the glass with matching ma rks if the windshield glass is reused.
WARNING:
Always wear safety glasses and heavy gloves to prevent injury.
CAUTION:
 Never use a cutting knife or power cutting tool when the windshield glass is reused.
 Be careful not to scratch the glass when removing.
 Never set or stand the glass on its edge. Small chips may develop into cracks.
INSTALLATION
 The dam sealant rubber and insulator should be installed in position.
 Use a genuine Nissan Urethane Adhesive Kit (if available) or an equivalent and follow the instructions pro- vided with it.
 Open a door window while the urethane adhesive is curing. This prevents the glass from being forced out by
passenger room air pressure when all door windows are closed.
 The molding must be installed securely so that it is in position and leaves no clearance.
 Inform the customer that the vehicle should rema in stationary until the urethane adhesive has completely
cured (approximately 24 hours). Curing time varies with temperature and humidity.
WARNING:
 Keep heat and open flames away as primers and adhesive are flammable.
 The materials contained in the ki t are harmful if swallowed, and may irritate skin and eyes. Never let
them come in contact with the skin and eyes.
 Use in an open, well ventilated location. Never br eathe the vapors. They may be harmful if inhaled.
Move immediately to an area with fresh air if affected by vapor inhalation.
 Driving the vehicle before the urethane adhesive has completely cured may affect the performance
of the windshield in case of an accident.
CAUTION:
 Perform adjustment of front wiper arms stop location. Refer to WW-66, "
Adjustment".
