climate control CADILLAC XLR V 2007 1.G User Guide

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 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.
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. Do not
drive the vehicle until all the windows are clear.

(Temperature)
This message displays when the transmission uid
in your vehicle is too hot. Stop and allow your
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. 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. You can continue to drive your
vehicle. If this message continues to display, have
the system repaired by your dealer as soon as
possible to avoid compressor damage.
ICE POSSIBLE
This message displays when the outside air
temperature is cold enough to create icy road
conditions. Adjust your driving accordingly.
209

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
if you notice a drop in heating and air conditioning
efficiency.
SERVICE ABS (Anti-lock Brake System)
If this message displays 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 dealer.
If the SERVICE ABS message is being displayed,
the Traction Control System (TCS) 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 beilluminated. SeeAnti-Lock Brake System Warning
Light on page 193andTraction Control System
(TCS) Warning Light on page 194. 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 dealer as
soon as possible. Adjust your driving accordingly.
SERVICE AFS (Adaptive Forward

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 vehicle until 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 377.

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.
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.
