Section 2 Features and Controls
108

Key In the Ignition
Never leave your vehicle with the keys inside, as it
is an easy target for joy riders or thieves. If you
leave the key in the ignition and park your vehicle,
a chime will sound, when you open the driver’s
door. Always remember to remove your key from
the ignition and take it with you. This will lock
your ignition and transmission. Also, always
remember to lock the doors.
The battery could be drained if you leave the key
in the ignition while your vehicle is parked.
You may not be able to start your vehicle after it
has been parked for an extended period of time.
Retained Accessory Power (RAP)
Your vehicle has a Retained Accessory Power
(RAP) feature which will allow certain features on
your vehicle to continue to work up to 10 minutes
after the ignition key is turned to LOCK.
The radio, power windows, and if the vehicle has a
sunroof and the OnStar
®System, will work when
the ignition key is in RUN or ACCESSORY. Once
the key is turned from RUN to LOCK, the windows
and sunroof will continue to work until a door is
opened. The radio will continue to work for up to
10 minutes or until the driver’s door is opened.
Starting the Engine
If your vehicle has the DURAMAX®Diesel engine,
see the DURAMAX®Diesel manual for more
information.
To place the transmission in the proper gear:
Move your shift lever to PARK (P) or NEUTRAL (N).
Your engine will not start in any other position -- this
is a safety feature. To restart when you are already
moving, use NEUTRAL (N) only.
Starting Procedure
1. With your foot off the accelerator pedal, turn
the ignition key to START. When the engine
starts, let go of the key. The idle speed will go
down as your engine gets warm. Do not
race the engine immediately after starting it.
Operate the engine and transmission gently to
allow the oil to warm up and lubricate all
moving parts.
134

The rails are notched at each end which allows
the tie-downs to be removed and placed on
another rail. To remove, pull the locator pin out
and slide the tie-down to the end of the rail
and pull back.
To remove or install cargo tie-downs at the front of
the bed, slide the corner cap towards the center of
the bed to expose the rail notches. To remove the
corner cap, pull either edge away from the rail.
To remove the system, loosen the toggle bolts
on each rail until they can be removed from the
bed of the truck. To replace the system, place the
toggle bolts and rails into their original locations
and tighten them to a torque setting of
12.5 ft-lbs (17
Y).
If the system is removed to install a bed liner,
make sure there is no bed liner material in
the installation points.
Notice:If you tie down cargo using the
horizontal slots on the top of the pickup box,
you may damage the box. Using the horizontal
slots on the top of the pickup box for tie-down
locations may cause damage to the pickup box
and would not be covered by your warranty.
Only use the tie-down loops if you do not have
the cargo management system.
Sunroof
If your vehicle has a power sliding sunroof, the
ignition needs to be turned to RUN, or the
Retained Accessory Power (RAP) must be
activated to open or close the sunroof. When RAP
is active, the sunroof will work for 10 minutes
after the ignition is turned off, or until the driver’s
door is opened. SeeRetained Accessory
Power (RAP) on page 134for more information.

The sunroof also has a roller sunshade that can be

sunroof in an open or closed position. To open the
sunshade, press and unlatch it, and roll it back. To
close, pull it forward and latch it into the closed
position.

201

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

the switch a second time. To express-close

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 deector 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 re-opened,
refer to the Manual-Close or Express-Close
functions described previously.

Care of the CD and DVD Player
The use of CD lens cleaners for CDs is not
advised, due to the risk of contaminating the lens
of the CD optics with lubricants internal to the
CD mechanism.
Fixed Mast Antenna
The xed mast antenna can withstand most car
washes without being damaged. If the mast should
ever become slightly bent, straighten it out by
hand. If the mast is badly bent, replace it.
Check occasionally to make sure the mast is
still tightened to its base. If tightening is
required, tighten by hand, then with a wrench
one quarter turn.
XM™ Satellite Radio Antenna
System
The XM™ Satellite Radio antenna is located on
the roof of your vehicle. Keep this antenna clear of
snow and ice build up for clear radio reception.
A vehicle with a sunroof might not get the
best performance from the XM™ system if the
sunroof is open.
Loading items onto the roof of your vehicle can
interfere with the performance of the XM™ system.
Make sure the XM™ Satellite Radio antenna is
not obstructed.
