2009 GMC SAVANA Owner's Manual

Setting Cruise Control
Cruise control will not work if the parking brake is set, or
if the master cylinder brake fluid level is low.
The cruise control light on the instrument panel cluster
comes on after the cruise control has been set to the
desired speed.
{CAUTION:
If you leave your cruise control on when you are not
using cruise, you might hit a button and go into
cruise when you do not want to. You could be
startled and even lose control. Keep the cruise
control switch off until you want to use cruise
control.
1. Press the
Ibutton.
2. Get up to the desired speed.
3. Press the SET−button located on the steering
wheel and release it.
4. Take your foot off the accelerator.
Resuming a Set Speed
If the cruise control is set at a desired speed and then the
brakes are applied, this shuts off the cruise control. But it
does not need to be reset.
Once the vehicle speed reaches about 25 mph (40 km/h)
or more, press the +RES button on the steering wheel.
The vehicle returns to the previously set speed and
stays there.
Increasing Speed While Using Cruise
Control
To increase the cruise speed while using cruise control:
•Press and hold the +RES button on the steering
wheel until the desired speed is reached, then
release it.
•To increase vehicle speed in small increments,
press the +RES button. Each time this is done,
the vehicle goes about 1 mph (1.6 km/h) faster.

Reducing Speed While Using Cruise
Control
To reduce the vehicle speed while using cruise control:
•Press and hold the SET– button on the steering
wheel until the desired lower speed is reached,
then release it.
•To slow down in very small amounts, press
the SET– button on the steering wheel briefly.
Each time this is done, the vehicle goes about
1 mph (1.6 km/h) slower.
Passing Another Vehicle While Using
Cruise Control
Use the accelerator pedal to increase the vehicle speed.
When you take your foot off the pedal, the vehicle will
slow down to the previous set cruise speed.
Using Cruise Control on Hills
How well the cruise control will work on hills depends
upon the vehicle speed, load, and the steepness of the
hills. When going up steep hills, you might have to step
on the accelerator pedal to maintain the vehicle’s speed.
When going downhill, you might have to brake or shift to
a lower gear to keep the vehicle’s speed down. When the
brakes are applied the cruise control turns off.
Ending Cruise Control
There are three ways to end cruise control:
•Step lightly on the brake pedal.
•Press the[button on the steering wheel.
•Press theIbutton on the steering wheel.

together with the following:
•Instrument Panel Lights
•Taillamps
•License Plate Lamps
2(Headlamps):Turns on the headlamps together
with the following lamps listed below.
•Parking Lamps
•Instrument Panel Lights
•Taillamps
•License Plate Lamps
If the headlamps are turned on while the vehicle is on,
the headlamps turn off automatically 10 minutes
after the ignition is turned off. If the headlamps are
turned on while the vehicle is off, the headlamps will
continue to stay on. To prevent the battery from
being drained, turn the control to the
Oposition.A warning chime sounds if the driver door is opened
while the ignition switch is off and the headlamps are on.
To change the headlamps from low beam to high
beam, push the turn signal/multifunction lever toward
the instrument panel.
Headlamps on Reminder
If a door is open, a reminder chime sounds when the
headlamps or parking lamps are manually turned on and
the key is out of the ignition. To turn off the chime, turn
the headlamp switch to off or auto and then back on, or
close and re-open the door. In the auto mode, the
headlamps turn off once the ignition is in LOCK/OFF or
may remain on until the headlamp delay ends, if enabled
in the Driver Information Center (DIC). See “Exit Lighting”
underDIC Vehicle Customization on page 3-59.

Daytime Running Lamps (DRL)
Daytime Running Lamps (DRL) can make it easier for
others to see the front of your vehicle during the day.
Fully functional daytime running lamps are required on all
vehicles first sold in Canada.
The DRL system comes on in daylight when the
following conditions are met:
•The ignition is on.
•The exterior lamps control is in the AUTO position.
•The shift lever is not in P (Park).
•The light sensor determines it is daytime.
When the DRL are on, the taillamps, sidemarker,
instrument panel and other lamps will not be on.
The automatic headlamp system automatically switches
from DRL to the headlamps depending on the darkness
of the surroundings.
To turn off the DRL, turn the exterior lamp control to the
off position and then release it. For vehicles first sold
in Canada, the transmission must be in the P (Park)
position, before the DRL can be turned off.
Automatic Headlamp System
When it is dark enough outside and the headlamp
switch is in AUTO, the automatic headlamp system turns
on the headlamps, along with the taillamps, sidemarker,
parking lamps, roof marker lamps, and the instrument
panel lights. The radio lights will also be dim.
To turn off the automatic headlamp system, turn the
exterior lamps switch to the off position and then
release. For vehicles first sold in Canada, the
transmission must be in the P (Park) position, before
the automatic headlamp system can be turned off.
The vehicle has a light sensor located on the top of the
instrument panel. Do not cover the sensor or the
system will come on whenever the ignition is on.
The system may also turn on the headlamps when
driving through a parking garage or tunnel.
There is a delay in the transition between the daytime and
nighttime operation of the Daytime Running Lamps (DRL)
and the automatic headlamp systems so that driving
under bridges or bright overhead street lights does not
affect the system. The DRL and automatic headlamp
system is only affected when the light sensor sees a
change in lighting lasting longer than the delay.
3-15

If the vehicle is started in a dark garage, the automatic
headlamp system comes on immediately. Once the
vehicle leaves the garage, it takes approximately
30 seconds for the automatic headlamp system to
change to DRL if it is light outside. During that delay,
the instrument panel cluster may not be as bright
as usual. Make sure the instrument panel brightness
control is in the full bright position. SeeInstrument Panel
Brightness on page 3-16.
Instrument Panel Brightness
The knob for this feature is located next to the exterior
lamps control.
D(Instrument Panel Lights):Push knob to extend
and then turn clockwise or counterclockwise to brighten
or dim the instrument panel lights and the radio display.
This only works if the headlamps or parking lamps are on.
To turn on the dome lamps, with the vehicle doors
closed, turn the knob all the way clockwise.
Dome Lamps
The dome lamps come on when any door is opened.
They turn off after all the doors are closed.
The dome lamps can also be turned on by turning the
instrument panel brightness knob, located on the
instrument panel to the left of the steering column,
clockwise to the farthest position. In this position, the
dome lamps remain on whether a door is opened or
closed.
Dome Lamp Override
The dome lamp override button is located next to the
exterior lamps control.
The dome lamp override sets the dome lamps to remain
off or come on automatically when a door is opened.
E(Dome Lamp Override):Press the button in
and the dome lamps remain off when a door is opened.
Press the button again to return it to the extended
position so that the dome lamps come on when a door
is opened.
3-16

Entry/Exit Lighting
The vehicle has an illuminated entry/exit feature.
The dome lamps come on if the dome override button is
in the out position, when a door is opened or the key
is removed from the ignition.
Reading Lamps
For vehicles with reading lamps, press the button
located next to each lamp to turn it on or off.
The vehicle may also have reading lamps in other
locations. The lamps cannot be adjusted.
Electric Power Management
The vehicle has Electric Power Management (EPM) that
estimates the battery’s temperature and state of charge.
It then adjusts the voltage for best performance and
extended life of the battery.When the battery’s state of charge is low, the voltage is
raised slightly to quickly put the charge back in. When the
state of charge is high, the voltage is lowered slightly to
prevent overcharging. If the vehicle has a voltmeter gage
or voltage display on the Driver Information Center (DIC),
you may see the voltage move up or down. This is
normal. If there is a problem, an alert will be displayed.
The battery can be discharged at idle if the electrical
loads are very high. This is true for all vehicles. This is
because the generator (alternator) may not be spinning
fast enough at idle to produce all the power that is
needed for very high electrical loads.
A high electrical load occurs when several of the
following loads are on: headlamps, high beams, rear
window defogger, climate control fan at high speed,
engine cooling fans, trailer loads, and loads plugged into
accessory power outlets.
EPM works to prevent excessive discharge of the battery.
It does this by balancing the generator’s output and the
vehicle’s electrical needs. It can increase engine idle
speed to generate more power, whenever needed.
3-17

Battery Run-Down Protection
This feature shuts off the dome lamps if they are left
on for more than 10 minutes when the ignition is
in LOCK/OFF. This helps to prevent the battery from
running down.
Accessory Power Outlet(s)
The accessory power outlets can be used to connect
auxiliary electrical equipment, such as a cellular phone.
The vehicle may have two accessory power outlets
located on the instrument panel.
To use the accessory power outlet lift the cover.
The spring cap cover closes by itself when the outlet
is empty.Certain power accessory plugs may not be compatible
to the accessory power outlet and could result in
blown vehicle or adapter fuses. If you experience a
problem, see your dealer/retailer for additional
information on the accessory power plugs.
Notice:Adding any electrical equipment to the
vehicle can damage it or keep other components
from working as they should. The repairs would not
be covered by the vehicle warranty. Do not use
equipment exceeding maximum amperage rating of
20 amperes. Check with your dealer/retailer before
adding electrical equipment.
When adding electrical equipment, be sure to follow
the proper installation instructions included with the
equipment.
Notice:Improper use of the power outlet can cause
damage not covered by the warranty. Do not hang
any type of accessory or accessory bracket from the
plug because the power outlets are designed for
accessory power plugs only.
