Engine Exhaust
{CAUTION:
Engine exhaust can kill. It contains the
gas carbon monoxide (CO), which you
cannot see or smell. It can cause
unconsciousness and death.
You might have exhaust coming in if:
Your exhaust system sounds strange
or different.
Your vehicle gets rusty underneath.
Your vehicle was damaged in a
collision.
CAUTION: (Continued)
CAUTION: (Continued)

Your vehicle was damaged when
driving over high points on the road
or over road debris.
Repairs were not done correctly.
Your vehicle or exhaust system has
been modied improperly.
If you ever suspect exhaust is coming into
your vehicle:
Drive it only with all the windows
down to blow out any CO; and
Have your vehicle xed immediately.

Running the Engine While Parked
It is better not to park with the engine running. But if
you ever have to, here are some things to know.
{CAUTION:
Idling the engine with the climate control
system off could allow dangerous exhaust
into your vehicle. See the earlier caution
underEngine Exhaust on page 140.
Also, idling in a closed-in place can let
deadly carbon monoxide (CO) into your
vehicle even if the climate control fan is at
the highest setting. One place this can
happen is a garage. Exhaust — with
CO — can come in easily. NEVER park in
a garage with the engine running.
Another closed-in place can be a blizzard.
SeeWinter Driving on page 327.
{CAUTION:
It can be dangerous to get out of your
vehicle if the shift lever is not fully in
PARK (P) with the parking brake rmly
set. Your vehicle can roll. Do not leave
your vehicle when the engine is running
unless you have to. If you have left the
engine running, the vehicle can move
suddenly. You or others could be injured.
To be sure your vehicle will not move,
even when you are on fairly level ground,
always set your parking brake and move
the shift lever to PARK (P).
Follow the proper steps to be sure your vehicle
will not move. SeeShifting Into Park (P) on
page 136.
If you are pulling a trailer, seeTowing a Trailer on
page 340.

The Head-Up Display also displays a CHECK
GAGES message. The following messages could
appear on the instrument panel cluster when
CHECK GAGES appears:
Engine Coolant Temperature Warning. See
Engine Coolant Temperature Warning
Message on page 227.
Low Oil Pressure. SeeLow Oil Pressure
Message on page 229.
Charging System Indicator. SeeCharging
System Indicator Message on page 228.
Low Brake Fluid Warning. SeeLow Brake
Fluid Warning Message on page 232.
Under warning conditions, the CHECK GAGES
message will illuminate in the HUD. Look at
the instrument panel cluster for more information.Notice:If you try to use the HUD image as a
parking aid, you may misjudge the distance
and damage your vehicle. Do not use the HUD
image as a parking aid.
The HUD controls are
located to the left of the
steering wheel on the
instrument panel.
When the HUD is on, the speedometer reading will
always be displayed. The current audio system
information will only be displayed for three seconds
after the radio, tape or CD track status changes.
This will happen whenever one of the radio controls
is pressed, either on the radio or on the audio
steering wheel controls, if equipped.

To adjust the HUD so you can see it properly, do
the following:
1. Start your engine and turn the dimmer knob to
the desired HUD image brightness.
The brightness of the HUD image is determined
by the ambient light conditions in the direction
your vehicle is facing and where you have the
HUD dimmer knob set. If you are facing a dark
object or a heavily shaded area, your HUD may
anticipate that you are entering a dark area and
may begin to dim.
2. Adjust the driver’s seat. If you change your
seat position, you may have to readjust
your HUD.3. Press the UP or DN buttons until the HUD
image is easy to see and then press the DN
button until the HUD image is as low as
possible, but remains in full view straight
ahead near the front bumper.
The HUD image can only be adjusted up and
down, not side-to-side.
4. To turn the image off, turn the dimmer knob
counterclockwise until it stops.
If the sun comes out or it becomes cloudy, you
may need to adjust the HUD brightness again
using the dimmer knob. Polarized sunglasses
could make the HUD image harder to see.
When you rst start the vehicle the display will
show BUICK and the Buick logo for a few seconds.
If it is cold outside, this display may stay on for
up to a minute.
Clean the inside of the windshield as needed to
remove any dirt or lm that reduces the sharpness
or clarity of the HUD image.

To change the current mode, select one of the
following:
H(Vent):This mode directs air to the instrument
panel outlets.
)(Bi-Level):This mode directs half of the air to
the instrument panel outlets, then directs the
remaining air to the oor outlets. Cooler air
is directed to the upper outlets and warmer air to
the oor outlets.
6(Floor):This mode directs most of the air to
the oor outlets. Use this mode to send air to
the rear of the vehicle. Keep the area under the
front seats free of objects that could obstruct
airow to the rear of the vehicle.
The right knob can also be used to select defog or
defrost mode. For more information, see
“Defogging and Defrosting” later in this section.

prevent outside air and odors from entering your
vehicle or help heat or cool the air inside your
vehicle more quickly. Press this button to turn the
recirculation mode on or off. When the button
is pressed, an indicator light will come on.
The air-conditioning compressor also comes on.
The recirculation mode can be used with vent and
bi-level modes, but it cannot be used with oor,
defog, defrost or outside air modes.
Temperature Control:Turn the center knob
clockwise or counterclockwise to increase
or decrease the air temperature inside your
vehicle.
uA/C (Air Conditioning):Press this button to
turn the air-conditioning system on or off.

button will come on to let you know that air
conditioning is activated.
You may notice a slight change in engine
performance when the air-conditioning compressor
shuts off and turns on again. This is normal.
201

The system is designed to make adjustments to
help with fuel economy while still maintaining
the selected temperature.
On hot days, open the windows to let hot inside
air escape; then close them. This helps to reduce
the time it takes for your vehicle to cool down.
It also helps the system to operate more efficiently.
The air-conditioning system removes moisture
from the air, so you may sometimes notice a small
amount of water dripping underneath your
vehicle while idling or after turning off the engine.
This is normal.
Defogging and Defrosting
Fog on the inside of windows is a result of high
humidity, or moisture, condensing on the cool
window glass. This can be minimized if the climate
controls system is used properly. There are two
modes to clear fog or frost from your windshield.
Use the defog mode to clear the windows of fog or
moisture and warm the passengers. Use the
defrost mode to remove fog or frost from
the windshield more quickly.Turn the right knob to select the defog or
defrost mode.
-(Defog):This mode directs air to the
windshield and the oor outlets. When you select
this mode, the system turns off recirculation
and runs the air-conditioning compressor unless
the outside temperature is at or below freezing.
The recirculation mode cannot be selected while in
the defog mode.
0(Defrost):This mode directs most of the air to
the windshield and the side window outlets, with
some air directed to the oor outlets. In this mode,
the system will automatically turn off recirculation
and run the air-conditioning compressor, unless
the outside temperature is at or below freezing.
Recirculation cannot be selected while in the
defrost mode.
Do not drive the vehicle until all the windows are
clear.

button will come on to let you know that the
rear window defogger is activated.
The rear window defogger will turn off
approximately 10 minutes after the button is
pressed. If turned on again, the defogger will only
run for approximately ve minutes before
turning off. The defogger can also be turned off by
pressing the button again or by turning off the
engine.
Notice:Do not use anything sharp on the
inside of the rear window. If you do, you could
cut or damage the warming grid, and the
repairs would not be covered by your warranty.
Do not attach a temporary vehicle license,
tape, a decal or anything similar to the
defogger grid.
Dual Climate Control System
Your vehicle may have a dual climate control
system. With this system you can control
the heating, cooling, and ventilation for your
vehicle.
