2009 CADILLAC XLR climate control

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 15 mph (24 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 the vehicle is started. 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 it is blocked or covered, the system will not
function properly.
Outlet Adjustment
Use the thumbwheel to open or close the outlets.
Operation Tips

Clear away any ice, snow or leaves from the air
inlets at the base of the windshield that may
block the ow of air into the vehicle.
Use of non-GM approved hood deectors may
adversely affect the performance of the system.
Keep the area around the base of the instrument
panel console and air path under the seats clear
of objects to help circulate the air inside of the
vehicle more effectively.

enough outside to require the headlamps and/or other
exterior lamps. This message also displays if the
optional Rainsense™ wiping feature is on and the
Twilight Sentinel is off.
HIGH TRANS (Transmission) TEMP
(Temperature)
This message displays when the transmission uid in
the vehicle is too hot. Stop and allow the vehicle to idle
until it cools down or until this message is removed.
HIGH VOLTAGE
This message displays when the electrical charging
system is overcharging. To avoid being stranded, have
the electrical system checked by your dealer/retailer.
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.

NO FOB, OFF OR RUN?
This message displays when a keyless access
transmitter is not detected inside the vehicle while
you are trying to turn the ignition off. The vehicle may
be near a strong radio antenna signal causing the
keyless access system to be jammed. The vehicle will
remain in ACCESSORY until the vehicle is turned off or
is restarted, or ve minutes has expired. If you turn
the ignition off and you cannot nd the keyless access
transmitter, you will not be able to restart the vehicle.
The keyless access transmitter needs to be inside of the
vehicle in order for the vehicle to start. SeeStarting
the Engine on page 2-26for more information.
OVER SPEED WARNING
This message displays when the vehicle speed exceeds
a certain limit as required by some export countries.
A chime sounds when this message is displayed.
PRESS BRAKE TO START
This message displays to inform you that 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 displays when 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.
Reduced engine power can affect the vehicle’s ability to
accelerate. If this message is on, but there is no reduction
in performance, proceed to your destination. The
performance may be reduced the next time the vehicle is
driven. The vehicle may be driven at a reduced speed
while this message is on, but acceleration and speed may
be reduced. Anytime this message stays on, the vehicle
should be taken to your dealer/retailer for service as soon
as possible.
RIGHT DOOR AJAR
This message displays anytime the engine is running,
the transmission is not in P (Park), and the passenger
door is open or ajar. A chime sounds if the vehicle’s
speed is greater than 3 mph (5 km/h).
SERVICE A/C
This message displays when the electronic sensors that
control the air conditioning and heating systems are
no longer working. Have the climate control system
serviced by your dealer/retailer if you notice a drop in
heating and air conditioning efficiency.

{CAUTION:
Snow can trap engine exhaust under the vehicle.
This may cause exhaust gases to get inside.
Engine exhaust contains carbon monoxide (CO)
which cannot be seen or smelled. It can cause
unconsciousness and even death.
If the vehicle is stuck in the snow:
Clear away snow from around the base of
your vehicle, especially any that is blocking
the exhaust pipe.
Check again from time to time to be sure
snow does not collect there.
Open a window about two inches on the side
of the vehicle that is away from the wind to
bring in fresh air.
Fully open the air outlets on or under the
instrument panel.
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 2-36.
CAUTION: (Continued)
CAUTION: (Continued)
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.

Uniform Tire Quality Grading
Quality grades can be found where applicable on
the tire sidewall between tread shoulder and
maximum section width. For example:
Treadwear 200 Traction AA
Temperature A
The following information relates to the system
developed by the United States National Highway
Traffic Safety Administration (NHTSA), which
grades tires by treadwear, traction, and
temperature performance. This applies only to
vehicles sold in the United States. The grades are
molded on the sidewalls of most passenger car
tires. The Uniform Tire Quality Grading (UTQG)
system does not apply to deep tread, winter-type
snow tires, space-saver, or temporary use spare
tires, tires with nominal rim diameters of
10 to 12 inches (25 to 30 cm), or to some
limited-production tires.
While the tires available on General Motors
passenger cars and light trucks may vary with
respect to these grades, they must also conform
to federal safety requirements and additional
General Motors Tire Performance Criteria (TPC)
standards.
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.
