engine CADILLAC CTS 2007 1.G Owner's Manual

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 134.
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 316.
{CAUTION:
It can be dangerous to get out of your
vehicle if the automatic transmission 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 it is on fairly
level ground, always set the parking brake
and move the automatic transmission
shift lever to PARK (P), or the manual
transmission shift lever to NEUTRAL.
Follow the proper steps to be sure your vehicle will
not move. SeeShifting Into Park (P) (Automatic
Transmission) on page 130andParking Your
Vehicle (Manual Transmission) on page 132.
If you are parking on a hill and if you are pulling a
trailer, seeTowing a Trailer on page 328.

A high electrical load occurs when several of the
following loads are on: headlamps, high beams,
fog lamps, rear window defogger, climate
control fan at high speed, heated seats, engine
cooling fans, trailer loads, and loads plugged into
accessory power outlets.
EPM works to prevent excessive discharge of the
battery. It does this by balancing the generator’s
output and the vehicle’s electrical needs. It
can increase engine idle speed to generate more
power, whenever needed. It can temporarily
reduce the power demands of some accessories.
Normally, these actions occur in steps or levels,
without being noticeable. In rare cases at the
highest levels of corrective action, this action may
be noticeable to the driver. If so, a Driver
Information Center (DIC) message might be
displayed, such as Battery Saver Active or Service
Battery Charging System. If this message is
displayed, it is recommended that the driver
reduce the electrical loads as much as possible.
SeeDIC Warnings and Messages on page 232.Battery Run-Down Protection
Your vehicle has a feature to help prevent the
battery from being drained, in case the underhood
lamp, vanity mirror lamps, cargo lamps, reading
lamps, console, or glove box lamps are
accidentally left on, or something is left plugged
into the accessory power outlet or cigarette lighter.
If any of the accessory lamps are left on, they
will automatically time-out after about 20 minutes.
To reset the battery protection, all of the above
lamps must be turned off or the ignition must be in
the Acc. position.
Accessory Power Outlet(s)
Accessory power outlets can be used to connect
auxiliary electrical equipment, such as a cellular
telephone or CB radio.
186

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
yNz(Mode):Pressing the mode switch and
changing the mode cancels automatic operation
and places the system in manual mode. Press
AUTO to return to automatic operation.
The outboard air outlets will always receive airow
regardless of the mode selected. SeeOutlet
Adjustment on page 194to change this airow
from the outboard outlets.To change the current mode, select one of the
following:
Y(Vent):This mode directs air to the instrument
panel outlets.
\(Bi-Level):This mode directs approximately
half of the air to the instrument panel outlets,
and then directs most of the remaining air to the
oor outlets. In automatic operation, cooler air
is directed to the upper outlets and warmer air to
the oor outlets.
[(Floor):This mode directs most of the air to
the oor outlets with some air directed to the
outboard outlets (for the side windows), and a little
air directed to the windshield.
The mode switch can also be used to select the
defog mode. Information on defogging and
defrosting can be found later in this section.
yAz(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.

The rear window defogger will turn off about
10 minutes after the button is pressed, but if the
vehicle’s speed is above 30 mph (48 km/h),
the rear defogger will stay on continuously.
If turned on again, the defogger will only run for
about 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 mirror
when the rear window defogger button is on.
SeeOutside Heated Mirrors on page 141.
Notice:Do not try to clear frost or other
material from the inside of the front windshield
and rear window with a razor blade or anything
else that is sharp. This may damage the rear
window defogger grid and affect your radio’s
ability to pick up stations clearly. The repairs
wouldn’t 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.
j(Side Window Defog):Turn the thumbwheel
to this symbol to use the side window defog
setting. The air coming through the outlets will be
directed toward the side windows to clear fog.
k(Open):Turn the thumbwheel to this symbol to
open the outlets completely and allow the
maximum amount of air to enter your vehicle.
A small amount of air will still be directed to the
side windows.
l(Closed):Turn the thumbwheel to this symbol
to close the outlets and minimize the amount
of air entering the vehicle.

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 your 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
your vehicle more effectively.
Passenger Compartment Air Filter
The passenger compartment air lter traps most of
the pollen from the air entering your vehicle.
Like your vehicle’s engine air cleaner/lter, it needs
to be changed periodically. SeeScheduled
Maintenance on page 462.
Using the climate control system without the
passenger air lter installed may allow water or
other debris to enter the system. This could cause
a water leak or noises. Make sure to install a
new air lter after removing the old one.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 342
for more information on location.
Use the procedure listed below to replace the
passenger compartment air lter:
1. Turn the ignition to ON with the engine off.
2. Turn on the windshield wipers and turn them
off again when the wipers are straight on the
windshield.
This allows you access to the leaf screen.
The passenger compartment air lter is
located under the leaf screen.
195

3. Open the hood to access the engine
compartment. SeeHood Release on page 341
for more information.
4. Remove the four screws that hold the leaf
screen in place and lift off the screen by
lifting and sliding toward the center of
the vehicle.
5. Pull out on the two tabs located on each end
of the lter cover.
6. Lift the lter cover off by pulling it straight
upward.
7. 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 475for the correct part number
for the lter.
8. Reverse Steps 1 through 6 to reinstall
the cover.Steering Wheel Climate
Controls (CTS)
Your vehicle may have four controls that can be
programmed for use with the climate control
system.
The controls are located
on the left side of the
steering wheel.
SeeRecongurable Steering Wheel Controls
(SWC) (CTS) on page 169for more information on
programming these controls.

Warning Lights, Gages, and
Indicators
This part describes the warning lights and gages on
your vehicle. The pictures help to 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
the details show 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 as 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. Please follow this manual’s advice. Waiting to
do repairs can be costly and even dangerous.
So please get to know your vehicle’s warning lights
and gages. They can be a big help.
Your vehicle may also have a Driver Information
Center (DIC) that works along with the warning
lights and gages. SeeDriver Information Center
(DIC) on page 222for more information.

Speedometer and Odometer
The speedometer lets you see your speed in
either miles per hour (mph) or kilometers
per hour (km/h). The odometer shows how far
your vehicle has been driven, in either miles
(used in the United States) or kilometers (used in
Canada).
If your vehicle has to have a new odometer
installed, the new one may read the correct
mileage. This is because your vehicle’s computer
has stored the mileage in memory.
While the Driver Shift Control (DSC) feature is
active, the odometer will change to show the gear
range. SeeAutomatic Transmission Operation
on page 122for more information.
Trip Odometers
The trip odometer can record the number of miles
or kilometers traveled for up to two trips.
The trip odometer is part of the Driver Information
Center (DIC), for more information seeStatus
of Vehicle Systems on page 223.
For vehicles that have the navigation system,
see your Navigation System manual for more
information.
Tachometer
The tachometer displays the engine speed in
revolutions per minute (rpm).
Notice:If you operate the engine with the
tachometer in the shaded warning area, your
vehicle could be damaged, and the damages
would not be covered by your warranty. Do not
operate the engine with the tachometer in
the shaded warning area.
