2009 BUICK ENCLAVE climate control

The climate control system uses the
information from these sensors to
maintain comfort settings by
adjusting the temperature, fan
speed, and the air delivery mode.
The system may also supply cooler
air to the side of the vehicle
facing the sun. The recirculation
mode will also be used as needed
to maintain cool outlet temperatures.
Outlet Adjustment
Use the slider switch in the center
of the outlet, to change the direction
of the air ow. Use the thumbwheel
near the outlet to control the
amount of air ow or to shut off the
airow completely.
Keep all outlets open whenever
possible for best system
performance.
Operation Tips

Clear away any ice, snow, or
leaves from the air inlets at
the base of the windshield that
can block the ow of air into
the vehicle.
Use of non-GM approved hood
deectors can adversely affect
the performance of the system.
Keep the path under all seats
clear of objects to help circulate
the air inside the vehicle
more effectively.
If fogging reoccurs while in vent
or bi-level modes with mild
temperature throughout the
vehicle, turn on the air conditioner
to reduce windshield fogging.

DIC Warnings and
Messages
Messages are displayed on the DIC
to notify the driver that the status
of the vehicle has changed and that
some action may be needed by
the driver to correct the condition.
Multiple messages may appear one
after another.
Some messages may not require
immediate action, but you can press
any of the DIC buttons on the
instrument panel to acknowledge
that you received the messages and
to clear them from the display.
Some messages cannot be cleared
from the DIC display because
they are more urgent. These
messages require action before they
can be cleared. You should take
any messages that appear onthe display seriously and remember
that clearing the messages will
only make the messages disappear,
not correct the problem.
The following are the possible
messages that can be displayed
and some information about them.ALL WHEEL DRIVE OFF
If your vehicle has the All-Wheel
Drive (AWD) system, this message
displays when there is a compact
spare tire on the vehicle, when
the Antilock Brake System (ABS)
warning light comes on, or when the
rear differential uid is overheating.
This message turns off when
the differential uid cools.
The AWD system is disabled until
the compact spare tire is replaced
by a full-size tire. If the warning
message is still on after putting on
the full-size tire, you need to
reset the warning message. To
reset the warning message, turn the
ignition off and then back on

If the system fails to turn on or
activate, the StabiliTrak light along
with one of the following messages
will be displayed on the Driver
Information Center (DIC):
TRACTION CONTROL OFF,
SERVICE TRACTION CONTROL,
SERVICE STABILITRAK. If
these conditions are observed, turn
the vehicle off, wait 15 seconds,
and then turn it back on again
to reset the system. If any of these
messages still appear on the
Driver Information Center (DIC), the
vehicle should be taken in for
service. For more information on the
DIC messages, seeDriver
Information Center (DIC) on
page 3-41.The StabiliTrak light will ash on the
instrument panel cluster when the
system is both on and activated.
The system may be heard or
felt while it is working; this is normal.
The traction control disable button is
located on the instrument panel
below the climate controls.
The traction control part of
StabiliTrak can be turned off by
pressing and releasing the traction
control disable button.Traction control can be turned on
by pressing and releasing the
traction control disable button if not
automatically shut off for any
other reason.
When the traction control system is
turned off, the StabiliTrak light
and the appropriate traction control
off message will be displayed on
the DIC to warn the driver. The
vehicle will still have brake-traction
control when traction control is
off, but will not be able to use the
engine speed management system.
See “Traction Control Operation”
next for more information.
When the traction control system
has been turned off, system noises
may be heard and felt as a result
of the brake-traction control working.
It is recommended to leave the
system on for normal driving
conditions, but it may be necessary
to turn the system off if the vehicle is
stuck in sand, mud, ice or snow, and
you want to “rock” the vehicle to
attempt to free it. It may also be

CAUTION (Continued)
Adjust the Climate Control
system to a setting that
circulates the air inside the
vehicle and set the fan speed
to the highest setting. See
Climate Control System in
the Index.
For more information about
carbon monoxide, seeEngine
Exhaust on page 2-30.
Snow can trap exhaust gases
under your vehicle. This can
cause deadly CO (carbon
monoxide) gas to get inside. CO
could overcome you and kill you.
You cannot see it or smell it, so
you might not know it is in your
vehicle. Clear away snow from
around the base of your vehicle,
especially any that is blocking the
exhaust.
Run the engine for short periods
only as needed to keep warm,
but be careful.To save fuel, run the engine for only
short periods as needed to warm
the vehicle and then shut the engine
off and close the window most of
the way to save heat. Repeat
this until help arrives but only when
you feel really uncomfortable
from the cold. Moving about to keep
warm also helps.
If it takes some time for help to
arrive, now and then when you run
the engine, push the accelerator
pedal slightly so the engine
runs faster than the idle speed. This
keeps the battery charged to
restart the vehicle and to signal for
help with the headlamps. Do
this as little as possible to save fuel.
If Your Vehicle is Stuck
in Sand, Mud, Ice,
or Snow
Slowly and cautiously spin the
wheels to free the vehicle when
stuck in sand, mud, ice, or snow.
SeeRocking Your Vehicle to Get It
Out on page 4-16.If the vehicle has a traction system,
it can often help to free a stuck
vehicle. Refer to the vehicle’s
traction system in the Index. If stuck
too severely for the traction
system to free the vehicle, turn the
traction system off and use the
rocking method.
{CAUTION
If you let your vehicle’s tires spin
at high speed, they can explode,
and you or others could be
injured. The vehicle can overheat,
causing an engine compartment
re or other damage. Spin the
wheels as little as possible and
avoid going above 35 mph
(55 km/h) as shown on the
speedometer.
For information about using tire
chains on the vehicle, seeTire
Chains on page 5-56.

The vehicle is equipped with the
following wiring harness for towing
a trailer.
Basic Trailer Wiring
The trailer wiring harness, with a
seven-pin connector, is located at
the rear of the vehicle and is tied to
the vehicle’s frame. The harness
connector can be plugged into a
seven-pin universal heavy-duty
trailer connector available through
your dealer/retailer.The seven-wire harness contains
the following trailer circuits:Yellow: Left Stop/Turn Signal
Dark Green: Right Stop/Turn
Signal
Brown: Taillamps
Black: Ground
Light Green: Back-up Lamps
Red/Black: Battery Feed
Dark Blue: Trailer Brake*
*The fuse for this circuit is installed
in the underhood electrical center,
but the wires are not connected.
They should be connected by your
dealer/retailer or a qualied
service center.If the back-up lamp circuit is
not functional, contact your
dealer/retailer.
If a remote (non-vehicle) battery is
being charged, press the Tow/Haul
mode switch located on the center
console near the climate controls.
This will boost the vehicle system
voltage and properly charge the
battery. If the trailer is too light for
Tow/Haul mode, turn on the
headlamps (Non-HID only) as a
second way to boost the vehicle
system and charge the battery.
Engine Cooling When Trailer
Towing
The cooling system may temporarily
overheat during severe operating
conditions. SeeEngine Overheating
