Turn and Lane-Change
Signals
G:An arrow on the instrument
panel cluster flashes in the direction
of the turn or lane change.
To signal a turn, move the lever all
the way up or down.
To signal a lane change, raise or
lower the lever until the arrow
starts to flash. The turn signal
automatically flashes three times
and if the Tow/Haul Mode is active it
flashes six times. Holding the
turn signal lever for more than
one second causes the turn signals
to flash continually until the lever is
released. The lever returns to its starting
position when released.
If after signaling a turn or lane
change the arrow flashes rapidly or
does not come on, a signal bulb
may be burned out.
Have any burned out bulbs
replaced. If the bulb is not burned
out, check the fuse. See
Fuses and
Circuit Breakers on page 10‑43.Turn Signal On Chime
If the turn signal is left on for more
than 1.2 km (0.75 mi), a chime
sounds at each flash of the turn
signal and the message TURN
SIGNAL ON also appears in the
Driver Information Center (DIC). See
Lamp Messages on page 5‑37. To
turn off the chime and message,
move the turn signal lever to the off
position.

Radio
AM-FM Radio
Radio Data System (RDS)
The Radio may have a Radio Data
System (RDS). The RDS feature is
available for use only on FM
stations that broadcast RDS
information. This system relies upon
receiving specific information from
these stations and only works when
the information is available. While
the radio is tuned to an FM-RDS
station, the station name or call
letters display. In rare cases, a radio
station could broadcast incorrect
information that causes the radio
features to work improperly. If this
happens, contact the radio station.

Infotainment System 7-11
AM
The range for most AM stations is
greater than for FM, especially at
night. The longer range can cause
station frequencies to interfere with
each other. For better radio
reception, most AM radio stations
boost the power levels during the
day, and then reduce these levels
during the night. Static can also
occur when things like storms and
power lines interfere with radio
reception. When this happens, try
reducing the treble on the radio.
FM Stereo
FM stereo gives the best sound, but
FM signals reach only about 16 to
65 km (10 to 40 mi). Tall buildings or
hills can interfere with FM signals,
causing the sound to fade in
and out.
Cellular Phone Usage
Cellular phone usage may cause
interference with the radio. This
interference may occur when
making or receiving phone calls,
charging the phone's battery,
or simply having the phone on. This
interference causes an increased
level of static while listening to the
radio. If static is received while
listening to the radio, unplug the
cellular phone and turn it off.
Fixed Mast Antenna
(Multi-Band)
The multi-band antenna is located
on the roof of the vehicle. The
antenna is used for OnStar and the
XM Satellite Radio Service System
if the vehicle has these features.
Keep the antenna clear of
obstructions for clear reception.
Make sure there is sufficient
clearance when entering garages or
parking structures.
Fixed Mast
Antenna (Care)
The fixed mast antenna can
withstand most car washes
without being damaged as long as it
is securely attached to the base.
If the mast becomes slightly bent,
straighten it out by hand. If the mast
is badly bent, replace it.
Make sure there is sufficient
clearance when entering garages
or parking structures.
Occasionally check to make sure
the antenna is tightened to its base.
If tightening is required, tighten
by hand.

9-10 Driving and Operating
If it takes some time for help to
arrive, now and then when you run
the engine, push the accelerator
pedal slightly so the engine runs
faster than the idle speed. This
keeps the battery charged to restart
the vehicle and to signal for help
with the headlamps. Do this as little
as possible to save fuel.
If the Vehicle Is Stuck
Slowly and cautiously spin the
wheels to free the vehicle when
stuck in sand, mud, ice, or snow.
If the vehicle has a traction system,
it can often help to free a stuck
vehicle. Refer to the vehicle's
traction system in the Index. If stuck
too severely for the traction system
to free the vehicle, turn the traction
system off and use the rocking
method.
{WARNING
If the vehicle's tires spin at high
speed, they can explode, and you
or others could be injured. The
vehicle can overheat, causing an
engine compartment fire or other
damage. Spin the wheels as little
as possible and avoid going
above 56 km/h (35 mph).
See Tire Chains on page 10‑71.
Rocking the Vehicle to Get
It Out
Turn the steering wheel left and
right to clear the area around the
front wheels. Turn off any traction or
stability system. Shift back and forth
between R (Reverse) and a forward
gear, spinning the wheels as little as
possible. To prevent transmission
wear, wait until the wheels stop
spinning before shifting gears.
Release the accelerator pedal while
shifting, and press lightly on the
accelerator pedal when the transmission is in gear. Slowly
spinning the wheels in the forward
and reverse directions causes a
rocking motion that could free the
vehicle. If that does not get the
vehicle out after a few tries, it might
need to be towed out. See
Towing
the Vehicle on page 10‑89.
Vehicle Load Limits
It is very important to know how
much weight the vehicle can
carry. This weight is called the
vehicle capacity weight and
includes the weight of all
occupants, cargo, and all
nonfactory-installed options.
Two labels on the vehicle show
how much weight it was
designed to carry, the Tire and
Loading Information label and
the Certification/Tire label.

Black plate (48,1)GMC Savana Owner Manual - 2012 - 2nd - 11/11/11
9-48 Driving and Operating
Following Distance
Stay at least twice as far behind the
vehicle ahead as you would when
driving the vehicle without a trailer.
This can help to avoid situations
that require heavy braking and
sudden turns.
Passing
More passing distance is needed
when towing a trailer. Because the
rig is longer, it is necessary to go
much farther beyond the passed
vehicle before returning to the lane.
Backing Up
Hold the bottom of the steering
wheel with one hand. Then, to move
the trailer to the left, move that hand
to the left. To move the trailer to the
right, move your hand to the right.
Always back up slowly and,
if possible, have someone
guide you.
Making Turns
Notice:Making very sharp turns
while trailering could cause the
trailer to come in contact with the
vehicle. The vehicle could be
damaged. Avoid making very
sharp turns while trailering.
When turning with a trailer, make
wider turns than normal. Do this
so the trailer will not strike soft
shoulders, curbs, road signs, trees
or other objects. Avoid jerky or
sudden maneuvers. Signal well in
advance.
Turn Signals When Towing a
Trailer
The arrows on the instrument panel
flash whenever signaling a turn or
lane change. Properly hooked up,
the trailer lamps also flash, telling
other drivers the vehicle is turning,
changing lanes or stopping. When towing a trailer, the arrows on
the instrument panel flash for turns
even if the bulbs on the trailer are
burned out. For this reason you may
think other drivers are seeing the
signal when they are not. It is
important to check occasionally to
be sure the trailer bulbs are still
working.
Driving on Grades
Reduce speed and shift to a
lower gear
beforestarting down a
long or steep downgrade. If the
transmission is not shifted down, the
brakes might have to be used so
much that they would get hot and no
longer work well.
The vehicle can tow in D (Drive).
Shift the transmission to a lower
gear if the transmission shifts too
often under heavy loads and/or hilly
conditions.

Black plate (56,1)GMC Savana Owner Manual - 2012 - 2nd - 11/11/11
9-56 Driving and Operating
If using the wiring provided with the
factory-installed trailering package,
no holes need to be made in the
body of the vehicle. However, if an
aftermarket hitch is installed, holes
may need to be made in the body.
If holes are made in the body, then
be sure to seal the holes later when
the hitch is removed. If the holes are
not sealed, deadly carbon monoxide
(CO) from the engine's exhaust can
get into the vehicle as well as dirt
and water. See“Carbon Monoxide”
under Engine Exhaust on
page 9‑24.
Safety Chains
Always attach chains between the
vehicle and the trailer. Cross the
safety chains under the tongue of
the trailer to help prevent the tongue
from contacting the road if it
becomes separated from the hitch.
Always leave just enough slack so
the rig can turn. Never allow safety
chains to drag on the ground.
Trailer Brakes
A loaded trailer that weighs more
than 680 kg (1,500 lbs) needs to
have its own brake system that is
adequate for the weight of the
trailer. Be sure to read and follow
the instructions for the trailer brakes
so they are installed, adjusted and
maintained properly.
Trailer Wiring Harness
The optional heavy-duty trailer
wiring package includes a wiring
harness, with a seven-pin connector
at the rear of the vehicle and a
four-wire harness assembly under
the driver side of the instrument
panel. The four-wire harness
assembly comes without a
connector.
If the vehicle does not have a trailer
hitch, the seven-wire harness
assembly with connector is taped
together and located in a frame
pocket at the driver side rear left
corner of the frame. If the vehicle has a trailer hitch, the
seven-wire harness assembly with
connector is attached to a bracket
on the hitch platform. In both cases,
the seven-wire harness has a
connector and includes a 30-amp
feed wire.
The seven-wire harness connector
contains the following trailer circuits:
.Light Green: Back-up Lamps
(10A fuse)**
.White: Ground
.Dark Blue: Trailer Brake Signal
.Dark Green: Right Rear Stop
and Turn Signal*
.Red/Black Stripe: Battery Feed
(30A Fuse)
.Brown: Trailer Park Lamp
Supply Voltage (15A fuse)**
.Yellow: Left Rear Stop and Turn
Signal *

The four-wire harness (without
connector) contains the following
circuits:
.Black: Ground
.Red/White: Battery Feed
.Dark Blue: Trailer Brake Signal
.Light Blue: CHMSL/Stoplamp
Supply Voltage
* If the vehicle is a cutaway with
trailer provisions, a 15 amp fuse will
be shared for both left/stop trailer
turn and right/stop trailer turn
signals. However, the cutaway
lighting connector will have a
10 amp fuse for each signal.
** If the vehicle is a cutaway with
trailer provisions, a 15 amp fuse will
be shared for trailer park lamps and
cutaway rear lighting connector park
lamps. Also, a 10 amp fuse will be
shared for trailer back-up lamps and
cutaway rear lighting connector
back-up lamps.
Tow/Haul Mode
This button is on the instrument
panel, to the right of the steering
wheel.
Pressing this button turns on and off
the Tow/Haul Mode.
This indicator light on the instrument
panel cluster comes on when the
Tow/Haul Mode is on.
Tow/Haul is a feature that assists
when pulling a heavy trailer or a
large or heavy load. See Tow/Haul
Mode on page 9‑32 for more
information. Tow/Haul is designed to be most
effective when the vehicle and
trailer combined weight is at least
75 percent of the vehicle Gross
Combined Weight Rating (GCWR).
See
“Weight of the Trailer” inTrailer
Towing on page 9‑50. Tow/Haul is
most useful under the following
driving conditions:
.When pulling a heavy trailer or a
large or heavy load through
rolling terrain.
.When pulling a heavy trailer or a
large or heavy load in stop and
go traffic.
.When pulling a heavy trailer or a
large or heavy load in busy
parking lots where improved low
speed control of the vehicle is
desired.
