engine CADILLAC CTS 2007 1.G User Guide

To prevent starter-motor gear damage, this
system also prevents cranking if the engine is
already running. The engine cranking can
be stopped by turning the ignition switch to the
ACCESSORY or OFF position.
2. If your engine will not start, or starts but then
stops, it could be ooded with too much
gasoline. Try pushing your accelerator pedal
all the way to the oor and holding it there
as you turn the key to START. If the vehicle
starts briey but then stops again, do the
same thing.
Notice:Your engine is designed to work with
the electronics in your vehicle. If you add
electrical parts or accessories, you could
change the way the engine operates. Before
adding electrical equipment, check with
your dealer. If you do not, your engine might
not perform properly. Any resulting damage
would not be covered by your vehicle’s
warranty.Engine Coolant Heater
Your vehicle may have an engine coolant heater.
In very cold weather, 0°F (−18°C) or colder,
the engine coolant heater can help. You will get
easier starting and better fuel economy during
engine warm-up.
Usually, the coolant heater should be plugged in
a minimum of four hours prior to starting your
vehicle. At temperatures above 32°F (0°C), use of
the coolant heater is not required. Your vehicle
may also have an internal thermostat in the
plug end of the cord. This will prevent operation of
the engine coolant heater when the temperature
is at or above 0°F (−18°C) as noted on the cord.
120

To Use the Engine Coolant Heater
1. Turn off the engine.
2. Open the hood and unwrap the electrical
cord. For the 2.8L V6 and the 3.6L V6
engines, the cord is located in the engine
compartment on the passenger’s side of the
vehicle in front of the fuse block. For the
6.0L V8 engine, the cord is located in
the engine compartment on the driver’s side
of the vehicle near the inner fender and above
the strut.
Remove the plastic cap to access the plug.
3. Plug it into a normal, grounded 110-volt AC
outlet.{CAUTION:
Plugging the cord into an ungrounded
outlet could cause an electrical shock.
Also, the wrong kind of extension cord
could overheat and cause a re. You
could be seriously injured. Plug the cord
into a properly grounded three-prong
110-volt AC outlet. If the cord will not
reach, use a heavy-duty three-prong
extension cord rated for at least 15 amps.
4. Before starting the engine, be sure to unplug
and store the cord as it was before to keep it
away from moving engine parts. If you do
not, it could be damaged.
How long should you keep the coolant heater
plugged in? The answer depends on the outside
temperature, the kind of oil you have, and
some other things. Instead of trying to list
everything here, we ask that you contact your
dealer in the area where you will be parking your
vehicle. The dealer can give you the best
advice for that particular area.

Automatic Transmission Operation
The shift lever is located on the center console
between the front seats.
There are several
different positions for
the shift lever.
PARK (P):This position locks the rear wheels.
It is the best position to use when you start the
engine because your vehicle cannot move easily.{CAUTION:
It is dangerous to get out of your vehicle
if the 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 you are on fairly level
ground, always set your parking brake
and move the shift lever to PARK (P).
SeeShifting Into Park (P) (Automatic
Transmission) on page 130. If you are
pulling a trailer, seeTowing a Trailer on
page 328.
122

Make sure the shift lever is fully in PARK (P)
before starting the engine. Your vehicle has an
automatic transmission shift lock control system.
You must fully apply your regular brakes rst
and then press the shift lever button before you
can shift from PARK (P) when the ignition key is
in ON. If you cannot shift out of PARK (P),
ease pressure on the shift lever and push the shift
lever all the way into PARK (P) as you maintain
brake application. Then press the shift lever button
and move the shift lever into another gear.
SeeShifting Out of Park (P) on page 132.
Notice:Shifting to REVERSE (R) while your
vehicle is moving forward could damage the
transmission. The repairs would not be covered
by your warranty. Shift to REVERSE (R) only
after your vehicle is stopped.
REVERSE (R):Use this gear to back up.
At low vehicle speeds, you can also use
REVERSE (R) to rock your vehicle back and forth
to get out of snow, ice, or sand without damaging
your transmission. SeeIf Your Vehicle is Stuck
in Sand, Mud, Ice, or Snow on page 320for
additional information.NEUTRAL (N):In this position, the engine does
not connect with the wheels. To restart when
you are already moving, use NEUTRAL (N) only.
You can also use NEUTRAL (N) when your
vehicle is being towed.
{CAUTION:
Shifting into a drive gear while your
engine is running at high speed is
dangerous. Unless your foot is rmly on
the brake pedal, your vehicle could move
very rapidly. You could lose control and
hit people or objects. Do not shift into a
drive gear while your engine is running at
high speed.
Notice:Shifting out of PARK (P) or
NEUTRAL (N) with the engine running at high
speed may damage the transmission. The
repairs would not be covered by your warranty.
Be sure the engine is not running at high
speed when shifting your vehicle.
123

While driving in sport mode, the transmission
may remain in a gear longer than it would
in the normal driving mode based on braking,
throttle input, and vehicle lateral acceleration.
2. To enter the DSC mode, press the shift lever
forward to upshift or rearward to downshift.
The odometer on the instrument panel cluster will
change from the mileage to a number indicating
the requested gear range when moving the
shift lever forward or rearward. SeeSpeedometer
and Odometer on page 200for more information
on the odometer.
While using the DSC feature, the vehicle will have
rmer shifting and increased performance. You
can use this for sport driving or when climbing or
descending hills, to stay in gear longer, or to
down shift for more power or engine braking.The transmission will only allow you to shift into
gears appropriate for the vehicle speed and engine
Revolutions Per Minute (RPM). The transmission
will not automatically shift to the next higher
gear if the engine RPM is too high.
If shifting is prevented for any reason, the currently
selected gear will ash multiple times, indicating
that the transmission has not shifted gears.
While in the DSC mode, the transmission will
automatically downshift when the vehicle comes to
a stop and while quickly applying the accelerator
to increase speed. This will allow for more
power during take-off.
When accelerating your vehicle from a stop in
snowy and icy conditions, you may want to shift
into second gear. A higher gear ratio allows you to
gain more traction on slippery surfaces.
125

NEUTRAL:Use this position when you start or
idle your engine. Your shift lever is in NEUTRAL
when it is centered in the shift pattern, not in
any gear.
REVERSE (R):To back up, press down the
clutch pedal, completely stop the vehicle, and shift
into REVERSE (R). Let up on the clutch pedal
slowly while pressing the accelerator pedal.
For the CTS, pull the shift lever quickly to the left
and then forward into gear.
For the CTS-V, the transmission has a safety
feature that prevents you from shifting into
REVERSE (R) while the vehicle is driven at
speeds greater than 3 mph (5 km/h). You will be
locked out if you try to shift into REVERSE (R)
while your vehicle is moving faster than 3 mph
(5 km/h). If you have turned your ignition off and
wish to park your vehicle in REVERSE (R),
you will have to overcome the lockout mechanism
by moving the shift lever quickly to the right,
and immediately forward into gear using more
force than a normal shift.Shift Speeds (Manual Transmission)
{CAUTION:
If you skip a gear when you downshift,
you could lose control of your vehicle.
You could injure yourself or others.
Do not shift down more than one gear
at a time when you downshift.
Notice:If you skip more than one gear when
you downshift, or if you race the engine when
you release the clutch pedal while downshifting,
you could damage the engine, clutch, driveshaft
or the transmission. Do not skip gears or race
the engine when downshifting.
If the vehicle speed drops below 20 mph (32 km/h),
or if the engine is not running smoothly, you should
downshift to the next lower gear. You may have to
downshift two or more gears to keep the engine
running smoothly or for good performance.
127

Skip Shift (CTS-V)
1r4:This message may appear in the message
center in the speedometer during light throttle, low
speed maneuvers (15 to 19 mph (24 to 31 km/h)).
When this message appears, you can only shift
from FIRST (1) to FOURTH (4) instead of
FIRST (1) to SECOND (2).
SeeOne-to-Four Shift Message (CTS-V Only) on
page 222for more information.
During the shift from FIRST (1) to FOURTH (4),
pull the shift lever straight back using light force on
the shift lever. You must complete the shift into
FOURTH (4) to turn off this feature. This helps get
the best possible fuel economy. The skip shift
feature is turned backed on when the vehicle is at
a complete stop and the digital speedometer
reads 0 mph (0 km/h).
Notice:Forcing the shift lever into any gear
except FOURTH (4), when the One – to – Four
Shift message comes on, may damage the
transmission. Shift only from FIRST (1) to
FOURTH (4) when the One – to – Four Shift
message comes on.The One – to – Four Shift message comes on when:The engine coolant temperature is higher than
169°F (76°C) and you are going 15 to 19 mph
(24 to 31 km/h).
You are pressing the accelerator pedal less
then a quarter of the way down.
Parking Brake
The parking brake pedal
is located on the lower
portion of the instrument
panel to the left of the
steering wheel.
To set the parking brake, hold the regular brake
pedal down with your right foot and push the
parking brake pedal down with your left foot.
128

Shifting Into Park (P)
(Automatic Transmission)
{CAUTION:
It can be dangerous to get out of your
vehicle if the shift lever is not fully in
PARK (P) with the parking brake rmly set.
Your vehicle can roll. 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 you are on fairly level ground, use
the steps that follow. If you are pulling a
trailer, seeTowing a Trailer on page 328.To shift into PARK (P), use the following steps:
1. Hold the brake pedal down with your right foot.
2. Move the shift lever into PARK (P) by
pressing the button on the front of the
shift lever while pushing the lever all the way
toward the front of the vehicle. Release
the button.
3. With your right foot still holding the brake
pedal down, set the parking brake with
your left foot. SeeParking Brake on page 128
for more information.
4. Turn the key to OFF.
5. Remove the key from the ignition switch and
take it with you. If you can leave your vehicle
with the key in your hand, the vehicle is in
PARK (P).
130

Leaving Your Vehicle With the Engine
Running (Automatic Transmission)
{CAUTION:
It can be dangerous to leave your vehicle
with the engine running. Your vehicle could
move suddenly if the shift lever is not fully
in PARK (P) with the parking brake rmly
set. And, if you leave the vehicle with the
engine running, it could overheat and even
catch re. You or others could be injured.
Do not leave your vehicle with the engine
running.
If you have to leave your vehicle with the engine
running, be sure your vehicle is in PARK (P)
and your parking brake is rmly set before you
leave it. After you have moved the shift lever into
PARK (P), hold the regular brake pedal down.
Then, see if you can move the shift lever
away from PARK (P) without rst pushing the
button on the shift lever. If you can, it means that
the shift lever was not fully locked into PARK (P).
Torque Lock (Automatic Transmission)
If you are parking on a hill and you do not shift your
transmission into PARK (P) properly, the weight of
the vehicle may put too much force on the parking
pawl in the transmission. You may nd it difficult to
pull the shift lever out of PARK (P). This is called
“torque lock.” To prevent torque lock, set the
parking brake and then shift into PARK (P) properly
before you leave the driver’s seat. To nd out how,
see “Shifting Into PARK (P)” listed previously.
If torque lock does occur, you may need to have
another vehicle push yours a little uphill to
take some of the pressure from the parking pawl
in the transmission, so you can pull the shift
lever out of PARK (P).
131

Engine Exhaust
{CAUTION:
Engine exhaust can kill. It contains the
gas carbon monoxide (CO), which you
cannot see or smell. It can cause
unconsciousness and death.
You might have exhaust coming in if:
The exhaust system sounds strange
or different.
Your vehicle gets rusty underneath.
Your vehicle was damaged in a
collision.
CAUTION: (Continued)
CAUTION: (Continued)

Your vehicle was damaged when
driving over high points on the road
or over road debris.
Repairs were not done correctly.
Your vehicle or the exhaust system
has been modied improperly.
If you ever suspect exhaust is coming into
your vehicle:
Drive it only with all the windows
down to blow out any CO; and
Have your vehicle xed immediately.
