Vent: From the closed position, press the rear of the
passenger's side switch to vent the sunroof. To close the
sunroof, press and hold the front of the passenger's
side switch.
Manual-Open/Manual-Close: To open the sunroof
press and hold the rear of the driver's side switch until
the sunroof reaches the desired position. To close the
sunroof, press and hold the front of the driver's side
switch until the sunroof reaches the desired position.
When the sunroof is opened, an air deflector will
automatically raise. The air deflector will retract when
the sunroof is closed.
If your vehicle is a crew
cab, there are two sunroof
switches located in the
overhead console above
the rearview mirror.
Express-Open/Express-Close: To express-open
the sunroof, fully press and release the rear of
the driver's side switch. The sunroof will open
automatically. To stop the sunroof partway, press the
switch a second time. To express-close the sunroof, fully
press and release the front of the driver's side switch.
The sunroof will close automatically. To stop the sunroof
partway, press the switch a second time.
The sunroof also has a sunshade which you can pull
forward to block sun rays. The sunshade must be
opened and closed manually.
Anti-Pinch Feature (Crew Cab Only): If an object is in
the path of the sunroof while it is closing, the anti-pinch
feature will detect the object and stop the sunroof
from closing at the point of the obstruction. The sunroof
will then open halfway, and the air deflector will raise.
To close the sunroof once it has re-opened, refer to the
Express-Close or Manual-Close functions described
previously. If the sunroof is in the vent position,
and there is an object in the path of the sunroof when it
closing, the anti-pinch feature will detect the object
and stop the sunroof. To close the sunroof once it has
stopped, refer to the Vent functions described previously.
Do not leave the sunroof open for long periods of time
while the vehicle is not in use. Debris can collect in the
tracks and damage the sunroof operation and plug
the water draining system.
