2010 GMC SIERRA DENALI child lock

Lockout Protection
This feature protects you from locking the key in the
vehicle when the key is in the ignition and a front door
is open.
If the driver's side power door lock switch is pressed
when the driver's door is open and the key is in the
ignition, all of the doors will lock and then the driver's
door will unlock.
If the passenger's side power door lock switch is
pressed when the front passenger's door is open and
the key is in the ignition, all of the doors will lock and
then the front passenger's door will unlock.
Rear Doors
You can open your doors from the inside or outside.
Your vehicle may also have a feature which prevents
children from opening the rear doors. SeeRear Door
Security Locks
on page 3‑12for more information.
Tailgate
{WARNING:
It is extremely dangerous to ride on the tailgate,
even when the vehicle is operated at low speeds.
People riding on the tailgate can easily lose
their balance and fall in response to vehicle
maneuvers. Falling from a moving vehicle may
result in serious injuries or death. Do not allow
people to ride on the tailgate. Be sure everyone in
your vehicle is in a seat and using a safety belt
properly.
On vehicles with a lock on the tailgate, use the key to
lock or unlock the tailgate.
Open the tailgate by lifting up on its handle while pulling
the tailgate toward you.
To shut the tailgate, firmly push it upward until it latches.
After you put the tailgate back up, pull it back towards
you to be sure it latches securely.

Power Windows
{WARNING:
Leaving children in a vehicle with the keys is
dangerous for many reasons, children or others
could be badly injured or even killed. They could
operate the power windows or other controls or
even make the vehicle move. The windows will
function and they could be seriously injured or
killed if caught in the path of a closing window. Do
not leave keys in a vehicle with children.
When there are children in the rear seat use the
window lockout button to prevent unintentional
operation of the windows.
Crew Cab shown
If your vehicle has power windows, the controls are
located on each of the side doors in the front and rear
for crew cab and extended cab models.
The driver's door has a switch for the passenger's and
rear windows as well. Your power windows will work
when the ignition has been turned to ACCESSORY or
RUN or when Retained Accessory Power (RAP) is
active. See Retained Accessory Power (RAP)
on
page 3‑24.
Press the switch down to lower the window, and pull up
the front of the switch to raise the window.
