2008 GMC SAVANA PASSENGER ignition

If the ignition is on when the parking brake is released,
the brake system warning light will go off.
Notice:Driving with the parking brake on can
overheat the brake system and cause premature
wear or damage to brake system parts. Verify that
the parking brake is fully released and the brake
warning light is off before driving.
If you are towing a trailer and are parking on any hill,
seeTowing a Trailer on page 4-28. That section shows
what to do first to keep the trailer from moving.

Shifting Out of PARK (P)
Your vehicle has an automatic transaxle shift lock
control system. You have to fully apply your regular
brakes before you can shift from PARK (P) when
the ignition is RUN. SeeAutomatic Transmission
Operation on page 2-22.
The shift lock control system is designed to do the
following:
•Prevent the ignition key from being removed unless
the shift lever is in PARK (P).
•Prevent movement of the shift lever out of
PARK (P), unless the ignition is in ON/RUN
and the regular brake pedal is applied.
The shift lock control system is always functional
except in the case of a dead battery or low voltage
(less than 9 V) battery.
If your vehicle has an uncharged battery or a battery
with low voltage, try charging or jump starting the
battery. SeeJump Starting on page 5-40for more
information.
To shift out of PARK (P) use the following:
1. Apply the brake pedal.
2. Move the shift lever to the desired position.If you still are unable to shift out of PARK (P):
1. Ease the pressure on the shift lever.
2. While holding down the brake pedal, push the shift
lever all the way into PARK (P)
3. Move the shift lever to the desired position.
If you are still having a problem shifting, then have your
vehicle serviced soon.
Parking Over Things That Burn
{CAUTION:
Things that can burn could touch hot exhaust
parts under your vehicle and ignite. Do not
park over papers, leaves, dry grass, or other
things that can burn.

Using Cruise Control on Hills
How well your cruise control will work on hills depends
upon your speed, load, and the steepness of the
hills. When going up steep hills, you may have to step
on the accelerator pedal to maintain the vehicle’s speed.
When going downhill, you may have to brake or shift
to a lower gear to keep the vehicle’s speed down.
Of course, applying the brake takes you out of cruise
control. Many drivers find this to be too much trouble
and do not use cruise control on steep hills.
Ending Cruise Control
There are three ways to end cruise control:
•Step lightly on the brake pedal.
•Press the cancel button on the steering wheel.
•Press the On/Off button on the steering wheel.
Erasing Speed Memory
When you turn off the cruise control or the ignition,
the cruise control set speed memory is erased.
Exterior Lamps
The exterior lamps control
is located on the instrument
panel to the left of the
steering wheel.
It controls the following systems:
•Headlamps
•Taillamps
•Parking Lamps
•License Plate Lamps
•Instrument Panel Lights
The exterior lamps control has four positions:
O(Off):Briefly turn the control to this position to
turn off the automatic headlamps and daytime running
lamps (DRL). Briefly turn to this position again to turn
the automatic headlamps or DRL back on.
For vehicles first sold in Canada, the off position only
works for vehicles that are shifted into the PARK (P)
position.
3-13

AUTO (Automatic):Turn the control to this position
to automatically turn on the headlamps at normal
brightness, together with the following:
•Parking Lamps
•Instrument Panel Lights
•Taillamps
•License Plate Lamps
;(Parking Lamps):Turn the control to this position
to turn on the parking lamps together with the
following:
•Instrument Panel Lights
•Taillamps
•License Plate Lamps
2(Headlamps):Turn the control to this position to
turn on the headlamps together with the following lamps
listed below.
•Parking Lamps
•Instrument Panel Lights
•Taillamps
•License Plate LampsWhen the headlamps are turned on while the vehicle is
on, the headlamps will turn off automatically 10 minutes
after the ignition is turned off. When 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 off position.
A warning chime sounds if the driver’s 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 3-58.

Daytime Running Lamps (DRL)
Daytime Running Lamps (DRL) can make it easier
for others to see the front of your vehicle during the day.
DRL can be helpful in many different driving conditions,
but they can be especially helpful in the short periods
after dawn and before sunset. Fully functional daytime
running lamps are required on all vehicles first sold
in Canada.
The DRL system will come 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 PARK (P).
•The light sensor determines it is daytime.
When the DRL are on, only the DRL lamps will be on.
The taillamps, sidemarker, and other lamps will not
be on. The instrument panel will not be lit up either.
When it begins to get dark, the automatic headlamp
system will switch from DRL to the headlamps.
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 PARK
(P) 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 will turn on
the headlamps at the normal brightness along with other
lamps such as 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 PARK (P) position, before the automatic
headlamp system can be turned off.
The vehicle has a light sensor located on the top of
the instrument panel. Be sure it is not covered, or
the system will be on whenever the ignition is on.
The system may also turn on the headlamps when
driving through a parking garage, heavy overcast
weather, or a tunnel. This is normal.
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 will only be affected when the light sensor sees
a change in lighting lasting longer than the delay.

Entry/Exit Lighting
Your vehicle has an illuminated entry/exit feature.
When a door is opened or the key is removed from
the ignition, the dome lamps will come on if the dome
override button is in the out position.
Reading Lamps
For vehicles with reading lamps, press the button
located next to each lamp to turn it on or off.
Your vehicle may also have reading lamps in other
locations. To turn each one on or off, press the button
located next to the lamp. 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 voltmetergage 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.
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.
This will help prevent the battery from running down.
3-17

Rear Window Defogger
Some vehicles may have a rear window defogger.
<(Rear Window Defogger):Press this button to turn
the rear window defogger on or off. Be sure to clear
as much snow from the window as possible.
The rear window defogger uses a warming grid to
remove fog or frost from the rear window and only
works when the ignition is in ON/RUN.
The rear window defogger turns off several minutes after
the button is pressed. If turned on again, the defogger
will run for several more minutes before turning off.
The defogger can also be turned off by pressing the
button again or by turning off the engine.
Notice:Do not use a razor blade or sharp object to
clear the inside rear window. Do not adhere anything
to the defogger grid lines in the rear glass. These
actions may damage the rear defogger. Repairs
would not be covered by your warranty.
Outlet Adjustment
Use the outlets located near the center and on the sides
of the instrument panel to change the direction of airflow.
Operation Tips
•Clear away any ice, snow or leaves from the air
inlets at the base of the windshield that may
block the flow of air into your vehicle.
•Use of non-GM approved hood deflectors may
adversely affect the performance of the system.
•Keep the path under the front seats clear of objects
to help circulate the air inside of your vehicle more
effectively.
