Re-Calibration
Condition
Some customers may comment that the sunroof may not close completely or after reaching closed position does not stop and continues to operate until the vent position is reached.
Re-Calibration Description
Sunroof Control Unit (SCU) has been designed to memorize closing and opening steps. However, the above condition may occur due to a loss of the memorized positioning data. The memorized positioning data can be lost when the operating current increases unusually over the specification operating current, 3.5 ~ 4.0 ampere because the foreign material is on sunroof guide rail or an object blocks the sunroof closing during operation.
SCU Re-calibration Procedures
- Press the switch rearward direction until the sunroof tilted open. Release the switch when the sunroof has fully opened.
- Press the switch rearward direction until the sunroof tilted open. Release the switch when the sunroof has fully opened.
Important : If the sunroof opens slightly and stops, release then press the switch and hold it and repeat these steps until the sunroof opens fully.
- If the sunroof is stopped when close movement, Press the switch forward direction until the sunroof close fully.
- Press the switch rearward direction until the sunroof open for 15 seconds.
- Confirm the re-calibration procedures by performing sunroof opening and closing operation.

GENERAL DESCRIPTION AND SYSTEM OPERATION
Roof
The roof is a one-piece painted metal unit which incorporates a single solid headliner. There are two moldings, one per side on the vehicle’s roof, which enclose and hide the roof rail seams. The roof moldings are serviceable as individual units.
The one-piece formed headliner consists of a moldedsubstrate covered with a foam-backed cloth facing. Theone-piece construction requires that the headliner beserviced as a complete assembly.
Power Sunroof/Sunroof Control Switch
The sunroof has the following characteristics:
- Intended to provide light and air through the roof the vehicle.
- Built into the roof.
- Made of glass.
- Equipped with a sunshade that opens and closes manually.
- Powered by an electric motor.
- Controlled by a switch built into the map lamp assembly.
The sunroof control switch is located on the center of the map lamp assembly.
To operate the sunroof, the ignition must be ON.
Tilting the Sunroof, Open and Closed
To tilt open the rear end of the sunroof, press the switch rearward direction until the sunroof tilts open.
To close the sunroof from a tilted-open position, press the switch forward direction until the sunroof tilts closed.
Sliding the Sunroof, Open and Closed
To slide open the sunroof, press the switch rearward direction until the sunroof slides. If the sun shade is closed, the sunroof will pull the sunshade open when the sunroof slides open.
To close the sunroof from a slid-open position, press the switch forward direction until the sunroof slides closed.
Sun Visors with Vanity Mirror
The sun visors swing down in order to block out glare.
They also swing to the side when they are released from the support.
Passenger Assist Handles
There is a passenger assist handle for each rear outboard seat and for the front passenger seat. Passengers can use these handles to assist in keeping their balance over rough roads or during sharp turns.
