118 Instruments and Controls
{Warning
Before driving the vehicle, always
clear snow and ice from the hood,
windshield, roof, and rear of the
vehicle, including all lamps and
windows. Reduced visibility from
snow and ice buildup could lead
to a crash.
Wiper Parking
If the ignition is turned off while the
wipers are on
w,1, or3INT,
they will immediately stop.
If
zFRONT is then moved to
OFF before the driver door is
opened or within 10 minutes, the
wipers will restart and move to the
base of the windshield.
If the ignition is turned off while the
wipers are performing wipes due to
windshield washing or Rainsense,
the wipers continue to run until they
reach the base of the windshield.
Rainsense
With Rainsense, a sensor near the
top center of the windshield detects
the amount of water on the
windshield and controls the
frequency of the windshield wiper.
Keep this area of the windshield
clear of debris to allow for best
system performance.
3INT : Turn thezFRONT
band on the wiper lever to adjust the
sensitivity when Rainsense is
turned on.
. Turn the band up for more
sensitivity to moisture.
. Turn the band down to lower INT
setting for less sensitivity to
moisture. Move the band out of the
3INT
position to deactivate Rainsense.
zAUTO : Press to turn
Rainsense on or off. When turned
on and
zFRONT is in one of the
Rainsense wipe sensitivity positions
the wipers can be adjusted for more
or less sensitivity to moisture. When
turned off, the wipers operate as
timed intermittent wipers and can be
adjusted for more or less frequent
wipes.
If
zAUTO is turned on when the
ignition is turned on, or if the ignition
is on and the
zFRONT band is
in one of the sensitivity settings

Move the slider knobs (1) to change
the direction of the airflow.
Use the thumbwheels (2) near the
air vents to open or close off the
airflow. Operation Tips
.
Clear away any ice, snow,
or leaves from the air inlets at
the base of the windshield that
could block the flow of air into
the vehicle.
. Clear snow off the hood to
improve visibility and help
decrease moisture drawn into
the vehicle.
. When you enter a vehicle in cold
weather, press the fan up button
to the maximum fan level before
driving. This helps clear the
intake ducts of snow and
moisture, and reduces the
chance of fogging the inside of
the window.
. Keep the air path under the front
seats clear of objects to help
circulate the air inside of the
vehicle more effectively.
. Use of non-GM approved hood
deflectors can adversely affect
the performance of the system.
Check with your dealer before
adding equipment to the outside
of the vehicle.

Engine Heater
{Warning
Do not plug in the engine block
heater while the vehicle is parked
in a garage or under a carport.
Property damage or personal
injury may result. Always park the
vehicle in a clear open area away
from buildings or structures.
If equipped, the engine heater can
provide easier starting and better
fuel economy during engine
warm-up in cold weather conditions
at or below −18 °C (0 °F). Vehicles
with an engine heater should be
plugged in at least four hours before
starting. There may be an internal
thermostat in the plug end of the
cord, which will prevent engine
heater operation at temperatures
above −18 °C (0 °F).
To Use the Engine Heater
1. Turn off the engine.
2. Open the hood and unwrap the
electrical cord. The cord is by
the left front fender, next to the
engine compartment fuse
block.
Check the heater cord for
damage. If it is damaged, do
not use it. See your dealer for
a replacement. Inspect the
cord for damage yearly.
3. Plug the cord into a normal, grounded 110-volt AC outlet.
{Warning
Improper use of the heater cord
or an extension cord can damage
the cord and may result in
overheating and fire.
. Plug the cord into a
three-prong electrical utility
receptacle that is protected
by a ground fault detection

Warning (Continued)
function. An ungrounded
outlet could cause an
electric shock.
. Use a weatherproof,
heavy-duty, 15 amp-rated
extension cord if needed.
Failure to use the
recommended extension
cord in good operating
condition, or using a
damaged heater or
extension cord, could make
it overheat and cause a fire,
property damage, electric
shock, and injury.
. Do not operate the vehicle
with the heater cord

vehicle. Possible heater
cord and thermostat
damage could occur.
. While in use, do not let the
heater cord touch vehicle
parts or sharp edges. Never
close the hood on the
heater cord.
. Before starting the vehicle,
unplug the cord, reattach
the cover to the plug, and
securely fasten the cord.
Keep the cord away from
any moving parts.
4. Before starting the engine, be sure to unplug and store the
cord as it was before to keep it
away from moving engine
parts. If you do not, it could be
damaged.
The length of time the heater should
remain plugged in depends on
several factors. Ask a dealer in the
area where you will be parking the
vehicle for the best advice on this.

plugged in during the jump
starting procedure, they could be
damaged. The repairs would not
be covered by the vehicle
warranty. Whenever possible, turn
off or unplug all accessories on
either vehicle when jump starting.
