2004 GMC SAFARI start stop button

If you manually select SECOND (2), the transmission
will drive in second gear. You may use this feature
for reducing torque to the rear wheels when you
are trying to start your vehicle from a stop on slippery
road surfaces.
FIRST (1):This position gives you even more power
(but lower fuel economy) than SECOND (2). You
can use it on very steep hills, or in deep snow or mud.
If the shift selector lever is put in FIRST (1), the
transmission won’t shift into rst gear until the vehicle is
going slow enough.
Notice:Spinning the tires or holding the vehicle in
one place on a hill using only the accelerator
pedal may damage the transmission. If you are
stuck, do not spin the tires. When stopping on a hill,
use the brakes to hold the vehicle in place.Tow/Haul Mode Button
Your vehicle is equipped with a tow/haul button. The
button is located on the end of the column shift
lever. You can use this feature to assist when towing or
hauling a heavy load.
To select the tow/haul mode, press in the button. The
TOW/HAUL light on the instrument panel cluster
will come on. To go back to normal operation, press the
button again. The indicator light on the instrument
panel cluster will go out. SeeTow/Haul Mode Light on
page 3-36for more information.

Theft-Deterrent Feature
THEFTLOCK®is designed to discourage theft of your
radio. It works by using a secret code to disable all radio
functions whenever battery power is interrupted.
The THEFTLOCK
®feature for the radio may be used or
ignored. If ignored, the system plays normally and the
radio is not protected by the feature. If THEFTLOCK
®is
activated, your radio will not operate if stolen.
When THEFTLOCK
®is activated, LOC will appear on
the radio display to indicate a locked condition anytime
battery power has been interrupted. If your battery
loses power for any reason, you must unlock the radio
with the secret code before it will operate.

Then, during the rst 500 miles (800 km) that you
tow a trailer, don’t drive over 50 mph (80 km/h)
and don’t make starts at full throttle. This helps your
engine and other parts of your vehicle wear in at
the heavier loads.
See also “Driving on Grades” later in this section.
Three important considerations have to do with weight:
the weight of the trailer,
the weight of the trailer tongue
and the weight on your vehicle’s tires.
Tow/Haul Mode
Tow/haul is designed to assist while your vehicle is
pulling a large or heavy load or trailer. Tow/haul is most
useful while pulling such a load in rolling terrain, in
stop-and-go traffic, or when you need improved
low-speed control, such as when parking. The purpose
of the tow/haul mode is to:
Reduce the frequency and improve the predictability
of transmission shifts,
provide the same solid shift feel when pulling a
heavy load as when the vehicle is unloaded, and
improve control of vehicle speed while requiring less
throttle pedal activity.Press the button on the end of the shift lever to turn
tow/haul mode on and off. While activated, the indicator
light on the instrument panel will be on. Tow/haul
mode will turn off automatically when the ignition is
turned off. SeeTow/Haul Mode Light on page 3-36.
Tow/haul is most effective when the vehicle and trailer
combined weight is at least 75% of the vehicle’s
Gross Combined Weight Rating (GCWR). See “Weight
of the Trailer” later in this section.
Driving with tow/haul activated without a heavy load will
cause reduced fuel economy and unpleasant engine
and transmission driving characteristics, but will
not cause damage.
Weight of the Trailer
How heavy can a trailer safely be?
It depends on how you plan to use your rig. For
example, speed, altitude, road grades, outside
temperature and how much your vehicle is used to pull
a trailer are all important. And, it can also depend
on any special equipment that you have on your vehicle.
The following chart shows how much your trailer can
weigh, based upon your vehicle model and options.
