Enhanced Technology Glass
The vehicle may be equipped with Enhanced
Technology Glass (ETG). ETG is part of the overall
occupant protection system on passenger vans. ETG
may help to keep passengers sitting next to these fixed
windows from being ejected through the glass in
some, but not in all crashes. Even with this glass, safety
belts must still be worn at all times. For passenger
vans, use only ETG glass approved for your vehicle for
replacement when damaged.
The following table shows laminated glass location,
based on vehicle model and options.

Engine Exhaust
{WARNING:
Engine exhaust contains Carbon Monoxide (CO)
which cannot be seen or smelled. Exposure to CO
can cause unconsciousness and even death.
Exhaust may enter the vehicle if:
•The vehicle idles in areas with poor ventilation
(parking garages, tunnels, deep snow that
may block underbody airflow or tail pipes).
•The exhaust smells or sounds strange or
different.
•The exhaust system leaks due to corrosion or
damage.
•The vehicle’s exhaust system has been
modified, damaged or improperly repaired.
WARNING: (Continued)
WARNING: (Continued)
•
There are holes or openings in the vehicle
body from damage or after-market
modifications that are not completely sealed.
If unusual fumes are detected or if it is suspected
that exhaust is coming into the vehicle:
•Drive it only with the windows
completely down.
•Have the vehicle repaired immediately.
Never park the vehicle with the engine running in
an enclosed area such as a garage or a building
that has no fresh air ventilation.

Windshield Washer
The windshield wiper paddle is located on top of the
multifunction lever.
L(Washer Fluid):Push the paddle to spray washer
fluid on the windshield. The wipers will clear the window
and then either stop or return to the preset speed.
{WARNING:
In freezing weather, do not use your washer until
the windshield is warmed. Otherwise the washer
fluid can form ice on the windshield, blocking your
vision.
Cruise Control
{WARNING:
Cruise control can be dangerous where you
cannot drive safely at a steady speed. So, do not
use the cruise control on winding roads or in
heavy traffic.
Cruise control can be dangerous on slippery
roads. On such roads, fast changes in tire traction
can cause excessive wheel slip, and you could
lose control. Do not use cruise control on slippery
roads.
With cruise control, a speed of about 25 mph (40 km/h)
or more can be maintained without keeping your foot
on the accelerator. Cruise control does not work
at speeds below about 25 mph (40 km/h).
When the brakes are applied, cruise control is
turned off.
If the vehicle has StabiliTrak
®, and the system begins to
limit wheel spin, cruise control will automatically
disengage. SeeStabiliTrak
®System on page 5-5. When
road conditions allow the cruise control to be safely
used again, it can be turned back on.

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 bring the charge back up. When
the state of charge is high, the voltage is lowered slightly
to prevent overcharging. If the vehicle has a voltmeter
gage or a 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 are on, such as: headlamps, high beams, fog
lamps, rear window defogger, climate control fan at
high speed, heated seats, 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. It can temporarily reduce the power demands of
some accessories.
Normally, these actions occur in steps or levels, without
being noticeable. In rare cases at the highest levels of
corrective action, this action may be noticeable to the
driver. If so, a Driver Information Center (DIC) message
might be displayed, such as BATTERY SAVER ACTIVE,
BATTERY VOLTAGE LOW, or LOW BATTERY. If this
message is displayed, it is recommended that the driver
reduce the electrical loads as much as possible. SeeDIC
Warnings and Messages on page 4-44.

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.
