2005 CADILLAC XLR climate control

Climate Controls
Dual Climate Control System
With this system you can control the heating, cooling
and ventilation for your vehicle.
When your vehicle is rst started, the system will recall
the last temperature fan and mode settings for that driver.
Automatic Operation
AUTO (Automatic):When this button is pressed and
the temperature is set, the system will automatically
control the inside temperature, the air delivery mode, the
air-conditioning compressor and the fan speed. AUTO
will appear on the display.
1. Press the AUTO button.
2. Adjust the temperature to a comfortable setting
between 70°F (21°C) and 80°F (27°C).
Choosing the warmest or coldest temperature
setting will not cause the system to heat or cool any
faster. If you set the system at the warmest or
coldest temperature setting, the system will remain
in manual mode at that temperature and it will
not go into automatic mode.
In cold weather, the system will start at reduced fan
speeds to avoid blowing cold air into your vehicle
until warmer air is available. The system will
start out blowing air at the oor but may change
modes automatically as the vehicle warms up
to maintain the chosen temperature setting. The
length of time needed for warm up will depend on
the outside temperature and the length of time
that has elapsed since your vehicle was last driven.

3. Wait for the system to regulate. This may take from
10 to 30 minutes. Then adjust the temperature, if
necessary.
You can switch from English to metric units through the
Driver Information Center (DIC). SeeDIC Controls
and Displays on page 3-61for more information.
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.
Do not cover the solar sensor located in the center of
the instrument panel, near the windshield. For more
information on the solar sensor, see “Sensors” later in
this section.Manual Operation
wPWRx(Power/Temperature):Press the PWR
button on the left side of the climate control panel to turn
the entire climate control system on or off. Press the
up or down arrow on the switch to manually increase or
decrease the temperature inside the vehicle.
Press the PWR button on the right side of the climate
control panel to turn the passenger’s climate control
system on or off. Press the up or down arrow on
the switch to manually increase or decrease the
temperature for the passenger.
If the passenger’s PWR button is off, the driver’s
temperature switch controls the temperature for the
entire vehicle.
«9ª(Fan):Press this switch to increase or
decrease the fan speed. Pressing this switch cancels
automatic operation and places the system in manual
mode. Press AUTO to return to automatic operation.
If the airow seems low when the fan speed is at
the highest setting, the passenger compartment air lter
may need to be replaced. For more information, see
Passenger Compartment Air Filter on page 3-45
andScheduled Maintenance on page 7-4.

Sensors
There are sensors to measure the temperature and
sun’s effect on passenger comfort.
The solar sensor on your vehicle monitors the solar
radiation then uses the information to maintain the
selected temperature when operating in AUTO mode by
initiating needed adjustments to the temperature, the
fan speed and the air delivery system. The system may
also supply cooler air to the side of the vehicle facing
the sun. The recirculation mode will also be activated, as
necessary. Do not cover the solar sensor located on
the top of the instrument panel near the windshield
or the system will not work properly.
There is also a sensor located behind the front bumper.
This sensor reads the outside air temperature and
helps maintain the temperature inside the vehicle. The
outside temperature will be displayed in the navigation
system only when the engine is running. Any cover
on the front of the vehicle could give a false reading of
the temperature.If the outside temperature goes up, the display
temperature will not change until:The vehicle’s speed is above 10 mph (16 km/h) for
ve minutes.
The vehicle’s speed is above 32 mph (51 km/h) for
two and one-half minutes.
These delays prevent false readings. If the temperature
goes down, the outside temperature will be shown
when you start the vehicle. If it has been turned off for
less than three hours, the temperature will be recalled
from the previous vehicle operation.
There is also an inside temperature sensor located to
the left of the ignition button. The automatic climate
control system uses this sensor to receive information,
so if you block or cover it, the system will not function
properly.

Defogging and Defrosting
Fog on the inside of windows is a result of high humidity
(moisture) condensing on the cool window glass. This
can be minimized if the climate control system is used
properly. There are two modes to clear fog or frost from
your windshield. Use the oor/defog mode to clear the
windows of fog or moisture and warm the passengers.
Use defrost to remove fog or frost from the windshield
more quickly.
-(Floor/Defog):Press the mode button until the
defog mode appears on the display. This mode directs
the air between the windshield, oor outlets and
side windows. When you select this mode, the system
turns off recirculation and runs the air-conditioning
compressor unless the outside temperature is near or
below freezing. The recirculation mode cannot be
selected while in the oor/defog mode.
1(Defrost):Press this button to direct most of the
air to the windshield, with some air directed to the
side windows. In this mode, the system will automatically
turn off the recirculation and run the air-conditioning
compressor, unless the outside temperature is near or
below freezing. Recirculation cannot be selected while in
the defrost mode. Do not drive the vehicle until all the
windows are clear.
Rear Window Defogger
The rear window defogger uses a warming grid to
remove fog or frost from the rear window.
The rear window defogger will only work when the
engine is running.
=(Rear Window Defogger):Press this button to
turn the rear window defogger on or off. Be sure to clear
as much snow from the rear window as possible.
The rear window defogger will turn off approximately
10 minutes after the button is pressed when traveling less
than 30 mph (48 km/h). 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.
The heated outside rearview mirrors will heat to help
clear fog or frost from the surface of the mirrors
when the rear window defogger is on.
The rear window defogger and heated mirrors are
automatically disabled when the retractable hardtop is
moving or down.
Notice:Don’t use anything sharp on the inside of
the rear window. If you do, you could cut or damage
the warming grid, and the repairs wouldn’t be
covered by your warranty. Do not attach a temporary
vehicle license, tape, a decal or anything similar to
the defogger grid.

HIGH VOLTAGE:This message shows that the
electrical charging system is overcharging. To avoid
being stranded, have the electrical system checked by
your GM dealer. You can reduce the charging
overload by using the accessories. Turn on the lamps
and radio, set the climate control on AUTO and the
fan speed on HI, and turn the rear window defogger on.
You can monitor battery voltage on the DIC by
pressing the information button. The normal range is
11.5 to 15.5 volts when the engine is running.
HOT ENGINE–A/C OFF:This message displays when
the engine coolant becomes hotter than the normal
operating temperature. To avoid added strain on a hot
engine, the air conditioning compressor is automatically
turned off. When the coolant temperature returns to
normal, the A/C operation will automatically resume. You
can continue to drive your vehicle. If this message
continues to appear, have the system repaired by
your GM dealer as soon as possible to avoid
compressor damage.
ICE POSSIBLE:This message appears when the
outside air temperature is cold enough to create icy road
conditions.
LEFT DOOR AJAR:This message will display anytime
the vehicle engine is running, the transmission is not
in PARK (P) and the driver’s door is open or ajar.
A chime will sound when the vehicle’s speed is greater
than 3 mph (4.8 km/h).LOW BRAKE FLUID:This message will display if the
vehicle is running to inform the driver that the brake
uid level is low. Have the brake system serviced
by your GM dealer as soon as possible. See “Brake
Fluid” underBrakes on page 6-33.
LOW COOLANT:This message will appear when there
is a low level of engine coolant. Have the cooling
system serviced by your GM dealer as soon as possible.
SeeEngine Coolant on page 6-20.
LOW FUEL:This message will appear when the fuel
supply is less than 5 gallons (18.9 L) and the display is
turned off. A single chime will also sound when this
message is displayed.
LOW OIL LEVEL:For correct operation of the low oil
sensing system, your vehicle should be on a level
surface. A false LOW OIL LEVEL message may appear if
the vehicle is parked on a grade. The oil level sensing
system does not check for actual oil level if the engine
has been off for a short period of time, and the oil level is
never checked while the engine is running. If the LOW
OIL LEVEL message appears, and your vehicle has been
parked on level ground with the engine off for at least
30 minutes, the oil level should be checked by observing
the oil dipstick. Prior to checking the oil level, be sure the
engine has been off for a few minutes and your vehicle is
on a level surface. Then check the dipstick and add oil if
necessary. SeeEngine Oil on page 6-13.
3-66

NO FOB, OFF OR RUN?:This message is displayed
when you turn off the engine, but the vehicle does
not detect a keyless access transmitter in the vehicle.
The vehicle will remain in accessory mode until the
engine has been turned off or started, or ve minutes
has expired. If you select OFF, the vehicle cannot
be started again without a remote access transmitter in
the vehicle.
OVER SPEED WARNING:This message is displayed
when the vehicle speed exceeds a certain limit as
required by some export countries. A chime will sound
when this message is displayed.
PRESS BRAKE TO START:The brake pedal must be
applied to start the vehicle. Make sure you are
pressing the brake pedal all the way down.
REDUCED ENGINE POWER:This message informs
you that the vehicle is reducing engine power because
the transmission is being placed in gear under
conditions that may cause damage to the vehicle’s
engine, transmission or ability to accelerate.
RIGHT DOOR AJAR:The passenger’s door is open or
ajar when this message appears. The vehicle must
be running and the transmission not in PARK (P) for this
message to display. A chime will sound if the vehicle’s
speed is greater than 3 mph (5 km/h).SERVICE A/C:This message appears when the
electronic sensors that control the air conditioning and
heating systems are no longer working. Have the climate
control system serviced by your GM dealer if you
notice a drop in heating and air conditioning efficiency.
SERVICE ABS:If the SERVICE ABS message is
displayed when you are driving, stop as soon as
possible and turn the ignition off. Then start the engine
again to reset the system. If the message stays on,
or comes back on again while you are driving,
your vehicle is in need of service. See your GM dealer.
If the SERVICE ABS message is being displayed, your
Traction Control System and StabiliTrak
®System will
also be disabled. The Driver Information Center will scroll
three messages: SERVICE ABS, SERVICE TRACTION
SYS and SERVICE STABILITRAK, and the anti-lock
brake system and traction control warning lights on the
instrument panel cluster will be illuminated. SeeAnti-Lock
Brake System Warning Light on page 3-53andTraction
Control System (TCS) Warning Light on page 3-53. The
driver can acknowledge these messages by pressing the
RESET button three times. When the service message is
displayed the computer controlled systems will not assist
the driver and you should have the system repaired by
your GM dealer as soon as possible. Adjust your driving
accordingly.

If you get the overheat warning with no sign of steam,
try this for a minute or so:
1. In heavy traffic, let the engine idle in NEUTRAL (N)
while stopped. If it is safe to do so, pull off the road,
shift to PARK (P) or NEUTRAL (N) and let the
engine idle.
2. Set the climate controls to the highest heat setting
and fan speed and open the windows as necessary.
If you no longer have the overheat warning, you
can drive. Just to be safe, drive slower for about
10 minutes. If the warning does not come back on, you
can drive normally.
If the warning continues, pull over, stop, and park your
vehicle right away.
If there is still no sign of steam, idle the engine for three
minutes while you are parked. If you still have the
warning,turn off the engine and get everyone out of the
vehicleuntil it cools down. Also, see “Overheated
Engine Protection Operating Mode” later in this section.
You may decide not to lift the hood but to get service
help right away.Overheated Engine Protection
Operating Mode
This operating mode allows your vehicle to be driven to
a safe place in an emergency situation. If an overheated
engine condition exists and the DIC message ENGINE
HOT, STOP ENGINE is displayed, an overheat
protection mode which alternates ring groups of
cylinders helps prevent engine damage. In this mode,
you will notice a signicant loss in power and engine
performance. Driving extended miles (km) in the
overheat protection mode should be avoided.
Notice:After driving in the overheated engine
protection operating mode, to avoid engine damage,
allow the engine to cool before attempting any repair.
The engine oil will be severely degraded. Repair the
cause of coolant loss, change the oil and reset the oil
life system. SeeEngine Oil on page 6-13.
6-25

Treadwear
The treadwear grade is a comparative rating based on
the wear rate of the tire when tested under controlled
conditions on a specied government test course.
For example, a tire graded 150 would wear one and
a half (1.5) times as well on the government course as
a tire graded 100. The relative performance of tires
depends upon the actual conditions of their use,
however, and may depart signicantly from the norm
due to variations in driving habits, service practices and
differences in road characteristics and climate.
Traction – AA, A, B, C
The traction grades, from highest to lowest, are AA, A,
B, and C. Those grades represent the tire’s ability
to stop on wet pavement as measured under controlled
conditions on specied government test surfaces of
asphalt and concrete. A tire marked C may have poor
traction performance. Warning: The traction grade
assigned to this tire is based on straight-ahead braking
traction tests, and does not include acceleration,
cornering, hydroplaning, or peak traction characteristics.
Temperature – A, B, C
The temperature grades are A (the highest), B, and C,
representing the tire’s resistance to the generation
of heat and its ability to dissipate heat when tested
under controlled conditions on a specied indoor
laboratory test wheel. Sustained high temperature can
cause the material of the tire to degenerate and
reduce tire life, and excessive temperature can lead to
sudden tire failure. The grade C corresponds to a
level of performance which all passenger car tires must
meet under the Federal Motor Vehicle Safety Standard
No. 109. Grades B and A represent higher levels of
performance on the laboratory test wheel than the
minimum required by law.
Warning: The temperature grade for this tire is
established for a tire that is properly inated and not
overloaded. Excessive speed, underination, or
excessive loading, either separately or in combination,
can cause heat buildup and possible tire failure.
