2007 CADILLAC SRX Owners Manual

There is also an interior temperature sensor
located below the climate control system next to
the steering wheel.
There is also an ambient sensor located behind
the grille in front of the vehicle.
These sensors help the climate control system
automatically control the temperature setting. The
system can 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.
Do not cover any of the sensors or the climate
control system might not work 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 from the windshield.
W(Floor/Defog):Use this mode to clear the
windows of fog and warm the passengers.
The system turns off recirculation and runs the air
conditioning compressor unless the outside
temperature is at or below freezing. If recirculation
mode is selected while using the defog mode,
the system recirculates air initially but returns to
the fresh air mode after 10 minutes.
0(Defrost):Use this mode to remove fog or
frost from the windshield more quickly. When
selected, the system turns off recirculation
and runs the air conditioning compressor, unless
the outside temperature is at or below freezing.
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.
<(Rear Defogger):Press the center of the
right control 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 turns off about 20 minutes after the
button is rst pressed if the vehicle is moving at
slower speeds. At higher vehicle speeds, the rear
defogger can stay on continuously. Each
additional press runs the defogger for about
10 minutes.
The heated outside rearview mirrors also heat to
help clear fog or frost from the surface of the
mirror when the rear window defogger is on.
Notice:Do not use a razor blade or sharp
object to clear the inside rear window. Do not
adhere anything to the defogger grid lines
in the rear glass. These actions may damage
the rear defogger. Repairs would not be
covered by your warranty.
Outlet Adjustment
Use the knobs located in the center of each outlet
to change the direction of the airow. Use the
thumbwheels 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
could 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 path under the front seats clear of
objects to help circulate the air inside of the
vehicle more effectively.
If the airow seems low when the fan speed is
at the highest setting, the passenger
compartment air lter might need to be
replaced. For more information, see
Passenger Compartment Air Filter on
page 195.
Set the climate control system to AUTO fan
and mode and then adjust the temperature
setting up or down a few degrees for
best comfort.
194

Rear Air Conditioning System
If your vehicle has the rear air conditioning system
it has two fan speed selectors. One fan speed
selector is located in the front overhead console
and the other is located in the headliner above the
second row seats. The rear air conditioning
system is designed to provide cooled air only.
To operate the rear system using the front control,
just turn the knob to the fan position you want.
To use the rear control, rst turn the front control
to AUX, then the rear control can be used to
increase and decrease the airow.
Passenger Compartment Air Filter
The passenger compartment air lter helps remove
dust and pollen from the air entering the vehicle.
Like the vehicle’s engine air cleaner/lter, it
needs to be changed periodically. For how often
to change the passenger compartment air
lter, seeScheduled Maintenance on page 471.
The passenger compartment air lter is located
underneath the hood below the windshield
wiper arm on the passenger’s side of the vehicle.
SeeEngine Compartment Overview on page 356
for more information on location.

Use the procedure listed below to replace the
passenger compartment air lter:
1. Open the hood to access the engine
compartment. SeeHood Release on page 355
for more information. Locate the passenger
compartment air lter access panel door.
2. Push the two tabs on the access panel door
towards the windshield.3. While pressing forward, lift the access panel
out of the clipped position and pull towards
the front of the vehicle. This releases the clips
and allows the panel door to be removed.
4. Remove the old lter and insert a new one.
Make sure the arrow on the lter is pointing
toward the passenger compartment.
SeeNormal Maintenance Replacement Parts
on page 482for the correct part number
for the lter.
5. Reverse Steps 1 through 3 to reinstall the
cover.

Warning Lights, Gages, and
Indicators
This part describes the warning lights and gages
that may be on your vehicle. The pictures will
help you locate them.
Warning lights and gages can signal that something
is wrong before it becomes serious enough to
cause an expensive repair or replacement. Paying
attention to the warning lights and gages could also
save you or others from injury.
Warning lights come on when there may be or is a
problem with one of your vehicle’s functions. As
you will see in the details on the next few
pages, some warning lights come on briey when
you start the engine just to let you know they
are working. If you are familiar with this section,
you should not be alarmed when this happens.Gages can indicate when there may be or is a
problem with one of your vehicle’s functions. Often
gages and warning lights work together to let
you know when there is a problem with your
vehicle.
When one of the warning lights comes on and
stays on while you are driving, or when one of the
gages shows there may be a problem, check
the section that tells you what to do about
it. Waiting to do repairs can be costly – and even
dangerous. So please get to know your warning
lights and gages. They are a big help.
Your vehicle also has a Driver Information Center
(DIC) that works along with the warning lights
and gages. SeeDriver Information Center (DIC)
on page 214for more information.
197

Instrument Panel Cluster
The instrument panel cluster is designed to let you know at a glance how your vehicle is running. You will
know how fast you are going, how much fuel you are using and many of the other things you will need
to know to drive safely and economically.

Speedometer and Odometer
The speedometer lets you see your speed
in both miles per hour (mph) and kilometers
per hour (km/h). See “SPEEDOMETER” under
DIC Controls and Displays on page 215for more
information.
The odometer mileage can be checked without the
vehicle running. Your vehicle’s odometer works
together with the driver information center.
You can set a Trip A and a Trip B odometer. See
“Trip Fuel” underDIC Controls and Displays on
page 215for more information.
If your vehicle ever needs a new odometer
installed, the new one will be set to the correct
mileage total of the old odometer.
Tachometer
This gage indicates the engine speed in
revolutions per minute (rpm).
Engine Speed Limiter
This feature prevents the engine from operating at
too many revolutions per minute (rpm). When
the engine’s rpms are too high, the throttle
is closed to reduce speed. If this is not sufficient,
then the fuel supply to the engine will be
limited. When the rpms return to normal, the fuel
supply will return to normal. This helps prevent
damage to the engine.

Safety Belt Reminder Light
When the key is turned to ON or START, a chime
will come on for several seconds to remind
people to fasten their safety belts, unless the
driver’s safety belt is already buckled.
The safety belt light
will also come on
and stay on for
several seconds,
then it will ash for
several more.
This chime and light will be repeated if the driver
remains unbuckled and the vehicle is in motion.
If the driver’s belt is already buckled, neither
the chime nor the light will come on.
Passenger Safety Belt Reminder
Light
Several seconds after the key is turned to ON or
START, a chime will sound for several seconds to
remind the front passenger to buckle their safety
belt. This would only occur if the passenger airbag
is enabled. SeePassenger Sensing System on
page 81for more information. The passenger
safety belt light will also come on and stay on for
several seconds, then it will ash for several more.
This chime and light will
be repeated if the
passenger remains
unbuckled and
the vehicle is in motion.
If the passenger’s safety belt is buckled, neither
the chime nor the light will come on.
