NOTICE: 
Don’t  hold  a  cigarette  lighter  in  with  your  hand 
while 
it is heating. If you do, it won’t be able  to 
back  away  from  the heating  element  when  it’s 
ready.  That  can  make it  overload,  damaging  the 
lighter  and  the  heating element. 
There is a smaller ashtray in the rear of the center 
floor console. 
Sun Visors 
To block out glare,  you can swing down the top and 
bottom visors 
(if your vehicle has them). You can  also 
swing  the bottom  visor from  side-to-side.  Your visors 
may  have an extension that  can be pulled  out for 
additional glare protection and  a  strap  for holding small 
items, such 
as maps. 
Illuminated  Visor Vanity Mirror 
Pull  the  sun visor down and  lift the mirror cover to turn 
on  the lamps. 
Accessory  Inflator 
Your  vehicle  is equipped with an  air inflator  system. 
With 
it, you can  inflate things like air mattresses and 
basketballs, and  you can also  use it to bring your tires  up 
to  the proper pressure. 
The  air inflator  is located  in 
the rear compartment  on the 
passenger’s  side 
of the 
vehicle. 
To remove the 
cover,  pull the tab  on the 
cover and pull 
it off’. 
The  air  inflator  kit 
is stored in the rear  compartment of 
your vehicle. It includes  a I %foot (5.5 m) hose  with 
three nozzle adapters.

Inflating  something too much can make  it 
explode,  and 
you or others  could  be  injured.  Be 
sure  to read  the  inflator  instructions, and  inflate 
any  object  only  to  its recommended  pressure. 
To use  your  air  inflator, attach the  appropriate nozzle 
adapter,  if required,  to the end  of the hose. 
Then  attach that end  of 
the 
hose to the object  you wish 
to  inflate.  Remove 
the 
protective  cap  covering  the 
outlet.  Attach 
the other end 
of 
the hose  to  the outlet. 
Press the 
ON switch. 
If the  air inflator system  does not turn  on, the fuse  may 
be  blown 
or installed  incorrectly.  See  “Fuses and Circuit 
Breakers” 
in the  Index  or  see  your dealer  for  service. 
Your  air inflator  will automatically  shut  off after about 
10 minutes. To reset, press the ON switch  again. 
Don’t 
run your air inflator  for longer than 30 minutes  at 
one  time. 
If you  do, you  may  damage the system. After 
30 minutes,  wait  at least 10 minutes before restarting the 
air  inflator. 
To turn  off the air inflator, press OFF and detach  the 
hose, first  from the inflated  object, then from  the outlet. 
Replace  the protective  cap. Place the  inflator  kit tools 
in 
the pouch  and store it properly. 
To replace the cover, line up the tabs  at the  back  of  the 
cover  and put 
it in place.

Accessory  Power  Outlets 
With the accessory power outlets, you can plug  in 
auxiliary electrical  equipment.  There are four  accessory 
power outlets located throughout the vehicle. Two  are 
near the lower  center part 
of the instrument panel,  one is 
located  in 
the lower rear  of the center console  and the 
other  is located  in 
the rear of the vehicle in the air 
inflator compartment. Follow the proper installation 
instructions that  are included  with any electrical 
equipment  you install. 
These  circuits  are protected  by 
a fuse and have 
maximum current levels. 
NOTICE: 
When  using  the  accessory  power  outlets, 
maximum  electrical  load  must  not  exceed 
20 amps.  Always  turn off any  electrical 
equipment  when  not  in use. Leaving  electrical 
equipment  on  for  extended  periods  will  drain 
your battery. 
Sunroof (If Equipped) 
Your vehicle  may  be equipped  with a  power  sliding 
sunroof.  To open or  close your sunroof, the ignition  or 
RAP  needs to  be on.  See  “Retained Accessory Power” 
in  the  Index. 
Press  and release the  rear  side 
of the button in the mini 
console to open the sunroof.  You can press  the forward 
side 
of the  button to close the sunroof. Once the sunroof 
is closed,  press the forward  side of the button to open 
the  sunroof  to the  vent  position. 
The  sunroof 
is also equipped with a sunshade  which you

Do not  use  the transmitter  with any garage door opener 
that  does  not have  the “stop  and reverse”  feature.  This 
includes  any garage  door opener model manufactured 
before  April 
1, 1982. 
Be sure that pe~ple arid objects Lire clear of the garclge 
door- you ~1-e Iwogmmning! 
Your vehicle’s engine should  be turned  off while 
programming the transmitter. Follow these steps to 
program  up to three channels: 
1. If  you  have not previously  programmed  a universal 
channel,  proceed to Step 
2. Otherwise,  hold down 
the two outside buttons 
on the universal transmitter 
until the  red  light  begins  to flash rapidly 
(approximately 
20 seconds).  Then release  the 
buttons.  This procedure initializes  the memory and 
erases  any previous settings  for all three channels. 
2. Hold  the end of the hand-held  transmitter against the 
bottom surface 
of the universal transmitter so that 
you  can  still  see the red light.

3. 
4. 
Decide which one of the three  channels you want to 
program.  Using both hands,  press the hand-held 
transmitter  button and the desired button 
on the 
universal transmitter.  Continue 
to hold both buttons 
through  Step 
4. 
Hold down  both buttons  until you see the red  light 
on  the  universal transmitter  flash  rapidly.  The rapid 
flashing,  which could take up to 
90 seconds, 
indicates that the universal  transmitter  has  been 
programmed.  Release both buttons  once the light 
starts 
to flash rapidly. 
If you  have  trouble  programming  the universal 
transmitter, make  sure that you  have  followed  the 
directions  exactly  as described  and that the battery 
in the 
hand-held  transmitter  is not dead. If you still cannot 
program 
it, rotate  the hand-held  transmitter  end over end 
and  try again.  The universal transmitter  may  not  work 
with older  garage  door  openers that do not meet current 
Federal  Consumer  Safety Standards. 
If you cannot 
program the transmitter  after repeated  attempts, consult 
your 
GMC dealer.  Be 
sure  to  keep the original hand-held  transmitter 
in case you need to  erase and reprogram  the 
universal transmitter. 
Operating  the  Transmitter 
Press and hold the  appropriate button on the universal 
transmitter.  The red light  comes  on while the signal is 
being transmitted. 
Note that the effective transmission  range  of the 
universal transmitter  may differ  from the hand-held 
transmitter  and  from one channel  to another.

Training  a  Garage  Opener  with  a  “Rolling 
Code” Feature 
If  you programmed  the  universal  transmitter,  but  the 
garage  door  will  not open,  and 
if your  garage  door  opener 
was  manufactured  after 
1995, your  garage  door  may  have 
a  security  feature  that  changes  the  “code”  of  your  garage 
door  opener  every  time  it  is  opened  or closed. 
To determine  if your  garage  door opener has this 
“rolling  code”  feature,  press the appropriate  button on 
the  universal transmitter that  was programmed. 
If the 
red light flashes rapidly  for  one to two seconds,  then 
turns  solid,  your garage  door opener has this  feature. 
To program a garage door  opener  with the rolling code 
feature,  do  the following: 
1. Program your hand-held  transmitter to  the universal 
transmitter by  following the steps provided under 
“Programming the Transmitter” earlier  in 
this  section. 
2. 
3.

6. 
Remove the  cover panel from the  garage  door 
opener receiver. 
It is  located near the garage door 
opener  motor.

receiver. The exact location and color will  vary 
among brands. 
Press the training button  on  the garage door  opener 
receiver for  one to two  seconds. 
Return to your vehicle and press the programmed 
button on  the universal transmitter 
until the  red  light 
flashes rapidly  (about  two  seconds). 
Release  the button, then press  it again  to confirm it 
was  programmed 
to the garage  door  opener receiver.
