child lock GMC SIERRA 2010 User Guide

To open a rear access
door from the inside,
the front door must be
opened first. Then, use
the handle located on the
inside of the rear access
door to open.
Crew Cabs
If your vehicle is a crew cab, 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 3‑10for
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.

Manual Windows
Turn the hand crank on each door to manually raise or
lower the manual windows.
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 3‑23.
Press the switch down to lower the window, and pull up
the front of the switch to raise the window.

Try to adjust the speed so you can drive through the
curve. Maintain a reasonable, steady speed. Wait to
accelerate until out of the curve, and then accelerate
gently into the straightaway.
Steering in Emergencies
There are times when steering can be more effective
than braking. For example, you come over a hill and
find a truck stopped in your lane, or a car suddenly
pulls out from nowhere, or a child darts out from
between parked cars and stops right in front of you.
These problems can be avoided by braking—if you can
stop in time. But sometimes you cannot stop in time
because there is no room. That is the time for evasive
action —steering around the problem.
The vehicle can perform very well in emergencies
like these. First, apply the brakes. See Braking
on
page 5‑3. It is better to remove as much speed as
possible from a collision. Then steer around the
problem, to the left or right depending on the
space available.
An emergency like this requires close attention and a
quick decision. If holding the steering wheel at the
recommended 9 and 3 o'clock positions, it can be
turned a full 180 degrees very quickly without removing
either hand. But you have to act fast, steer quickly, and
just as quickly straighten the wheel once you have
avoided the object.
The fact that such emergency situations are always
possible is a good reason to practice defensive driving
at all times and wear safety belts properly.
