Exterior Lamp Controls
The following exterior lighting
features apply to vehicles first sold
in the United States.
The vehicle has Daytime Running
Lamps (DRL) and an Automatic
Headlamp System (AHS). The DRL
and AHS can be turned to OFF with
the headlamp switch when the
transmission is in P (Park) and the
engine is at idle. If the engine is not
turned off, the DRL and AHS will
remain OFF when the transmission
is placed in gear. The vehicle may
be driven with the lamps off for one
ignition cycle.
The vehicle may have been built
with SEO 9G8, DRL AND AHS
DISABLE. This feature turns off
DRL and AHS and requires manual
control of the exterior lighting. See
your dealer to restore the DRL and
AHS to normal operation.For vehicles first sold in Canada,
the DRL and AHS can be turned off
if the transmission is in P (Park).
See
“DRL” in the owner manual.Special Features
The following standard features are
disabled in the Police Package and
Special Service Package.
.Entry Lighting and Exit Lighting
.Remote Keyless Entry Feedback
(Horn Beep) and (Lamps Flash)
Automatic Door Locking is standard.
If you need it disabled, see your
dealer.
The vehicle may have SEO UTQ
which disables the theft deterrent
system visual and audible warning.
See “Vehicle Security” in the owner
manual.

Starting and
Operating
Fast Idle System
While parked with the engine idling
for an extended period, turn off the
following factory equipment if
emergency lighting and
communication equipment are
operating:
.Air Conditioner
.Fan
.Rear Window Defogger
.Factory Audio System
See “Running the Vehicle While
Parked” in the owner manual.
Engine Idle Speed - Alternator
Output
Normal idle speed for the engine is
set for 600 rpm. To increase
alternator output while the
transmission remains in P (Park) or
N (Neutral), and the electrical load
on the alternator is large enough,
the engine idle speed can rise to as
high as 800 to 1000 rpm.

6. Reconnect the negative (−)battery cable to the battery.
Torque the bolt to 5 Y
(3.6 lb ft).
7. Reset the clock time and radio pushbuttons as desired.
The 12‐volt battery power is
supplied through two underhood
mega fuses, one 125 amp and one
60 amp. This underhood power is
fed to the breaker/relay center via a
harness that passes through the
driver side front of the dash, and
routes across the instrument panel
to a position forward of the glove
box. The breaker/relay center is
mounted to the instrument panel
structure forward of the glove box.
The center includes a plastic
bracket, two relays, two 30 amp
breakers and three 50 amp mega
circuit breakers.
Two 30 amp breakers supply power
from the underhood 60 amp mega
fuse through the contacts of the
control relays to 3.0 mm² (12 gauge)
blunt cut wires. These two blunt cut leads are part of wire coil under the
instrument panel near the center of
the vehicle.
Each relay is operated by a 0.5 mm²
(20 gauge) blunt cut, light or dark
blue control lead included in the
122 cm (4 ft) loop of wire coiled
under the instrument panel.
Three 50 amp mega circuit
breakers, protected by three fusible
links, supply power directly from the
underhood 125 amp mega fuse
through three, 5.0 mm² (10 gauge)
wires. Two of the wires are routed
through the body harness to buss
junction blocks in the left rear of the
cargo area and secured near the
jack and tools. This 122 cm (4 ft) of
coiled wires can be accessed by
removing the cup holder on the top
of the trim panel. The third 5 mm²
(10 gauge) wire is a blunt cut lead
which is part of the 122 cm (4 ft)
loop of wire coiled under the
instrument panel near the center of
the vehicle.
An 8 mm² (8 gauge) ground lead is
also provided, and it is located
under the front passenger sill plate.
It can be accessed by removing the
sill plate and pulling the loop of wire
at the front of the plate. The lead is
122 cm (4 ft) long.
Blunt cut ignition controlled power
and signal circuits are also included
in the wire coiled under the
instrument panel near the center of
the vehicle. They include:
.*A yellow, 0.5 mm² (20 gauge)
circuit, Hot in ACCESSORY,
RUN or RAP (Retained
Accessory Power).
.A pink, 0.5 mm² (20 gauge)
circuit, Hot in START and RUN.
(7A maximum load)
.*A yellow/black, 0.5 mm²
(20 gauge) transmission park
signal. This circuit provides
switched power when the
transmission is in P (Park) and
the engine is running.

The circuit is at 0 volts when the
transmission is in any other
position, i.e., R (Reverse),
N (Neutral), D (Drive) or
M (Manual). Note that the circuit
is also at 12 volts with the
transmission in P (Park) and the
ignition in LOCK/OFF. To avoid
the possibility of undesired
parasitic electrical load with the
ignition in LOCK/OFF it is
suggested that the Park/Signal
circuit be isolated by routing it
through the normally open
contact of a customer furnished
ignition controlled relay.
.A dark green/white, 0.5 mm²
(20 gauge) Vehicle Speed
Signal (VSS) provides
4,000 pulses per mile.
*These two circuits share a
15 amp fuse. (10 amp combined
maximum load) Servicing Relays and Fuses

The following information tells how
to access the vehicle's relay and
breaker center for checking and
replacing breakers.
The breaker and relay center is
located behind and above the
instrument panel storage
compartment. Remove contents
from the storage tray. Using the tab
at the back of the compartment,
drop the tray down gently toward
the floor. It will hang from the hinge.
The breaker/relay center is located
above the right rear corner of the
storage compartment. The bracket
is attached to the instrument panel
structure with two screws.
Replace a 30 amp circuit breaker
with GM Part No. 12182117 circuit
breaker, or equivalent. Replace a
relay with a GM Part No. 12193604

Exterior Lamp
Emergency Flashing
System - SEO 6J7
SEO 6J7 provides a high-beam
headlamps flashing module, rear
lamps flashing and control wire for a
customer-furnished switch to turn
the module on or off. The flasher
control wire is coiled under the
center of the instrument panel. This
control lead may be combined with
the interior wiring leads for SEO 6J3
when that option is ordered with
SEO 6J7.
The headlamps flashing module is
located below the passenger side
front headlamp and forward of the
passenger side front wheel. The
module is connected to an inline
connector in the forward lamp
harness. The headlamps flashing
module is activated by the
application of 12 volts to a dark
green/red wire coiled in the
passenger side footwell.When activated, the driver and
passenger side high-beam
headlamps and the high-beam
instrument panel cluster light will
flash alternately at 2.4 flashes per
second.
When the headlamps flashing
module is turned on, the module
sends a signal to the Body Control
Module (BCM). The BCM alternately
flashes the stop lamps and backup
lamps. Depressing the brake pedal
will override the stop lamp flashing
and placing the transmission in
reverse will override the backup
lamp flashing.
Activation of the headlamp and
rearlamp flashing can be separated
by opening the dark-blue/yellow
BCM circuit at the flasher module
connector, C122–F, and applying a
customer-switched ground to the
harness side of the wire in the
connector.
During daylight conditions, the
Daytime Running Lamps (DRL) are
automatically turned off whenever
the headlamps flasher module is
activated. During nighttime
conditions, the low-beam
headlamps turn on automatically
while the high-beam headlamps
flash. Turning on the high-beam
headlamps manually with the turn
signal/multifunction lever will
override the flashing module and
the high-beam headlamps will
operate continuously.
