2008 CADILLAC CTS engine

The tachometer display on
the instrument panel cluster
will show which gear the
vehicle is in and a number
indicating the requested
gear range when moving
the shift lever forward
or rearward. See
Speedometer and
Odometer on page 3-32
for 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 lower 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.

Manual Transmission Operation
If your vehicle has a
manual transmission, the
shift lever is located on the
center console between the
front seats. The following
explains how to operate the
manual transmission.
FIRST (1):Press the clutch pedal and shift into
FIRST (1). Then slowly let up on the clutch pedal
as you press the accelerator pedal.
Shift into FIRST (1) when you are going less than
25 mph (40 km/h). If you come to a complete stop and
it is hard to shift into FIRST (1), put the shift lever in
NEUTRAL and let up on the clutch. Press the clutch
pedal back down. Then shift into FIRST (1).SECOND (2):Press the clutch pedal as you let up
on the accelerator pedal and shift into SECOND (2).
Then, slowly let up on the clutch pedal as you press
the accelerator pedal.
THIRD (3), FOURTH (4), FIFTH (5) and SIXTH (6):Shift
into THIRD (3), FOURTH (4), FIFTH (5) and SIXTH (6)
the same way you do for SECOND (2). Slowly let up on
the clutch pedal as you press the accelerator pedal.
To stop, let up on the accelerator pedal and press the
brake pedal. Just before the vehicle stops, press the
clutch pedal and the brake pedal, and shift to NEUTRAL.
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.

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.
Up-Shift Light
Vehicles with a manual
transmission may have
an up-shift light on the
instrument panel. This light
will show you when to shift
to the next higher gear for
the best fuel economy.
When this light comes on, you can shift to the next
higher gear if weather, road, and traffic conditions allow.
For the best fuel economy, accelerate slowly and
shift when the light comes on.
While you accelerate, it is normal for the light to go
on and off if you quickly change the position of
the accelerator. Ignore the light when you downshift.

A warning chime will sound if the parking brake is set,
the ignition is on, and the vehicle begins to move.
To stop the chime, fully release the parking brake.
If you are towing a trailer and parking on a hill,
seeTowing a Trailer on page 4-30for more information.
Shifting Into Park
(Automatic Transmission)
{CAUTION:
It can be dangerous to get out of the vehicle if
the shift lever is not fully in P (Park) with the
parking brake rmly set. The vehicle can roll.
If you have left the engine running, the vehicle
can move suddenly. You or others could be
injured. To be sure the 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 4-30.Use this procedure to shift into P (Park):
1. Hold the brake pedal down and set the parking
brake.
SeeParking Brake on page 2-44for more
information.
2. Move the shift lever into P (Park) by holding in the
button on the shift lever and pushing the lever all
the way toward the front of the vehicle.
3. Turn the ignition key to LOCK/OFF.
4. For vehicles with key access, remove the key and
take it with you. If you can leave your vehicle with
the ignition key in your hand, your vehicle is in
P (Park). Vehicles with the keyless access system,
take the keyless access transmitter with you.

Leaving Your Vehicle With the Engine
Running (Automatic Transmission)
{CAUTION:
It can be dangerous to leave the vehicle with
the engine running. The vehicle could move
suddenly if the shift lever is not fully in
P (Park) 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
the vehicle with the engine running.
If you have to leave your automatic transmission
vehicle with the engine running, be sure your vehicle
is in P (Park) and your parking brake is rmly set before
you leave it. After you have moved the shift lever into
P (Park), hold the regular brake pedal down. Then, see if
you can move the shift lever away from P (Park) without
rst pushing the button.
If you can, it means that the shift lever was not fully
locked into P (Park).
Torque Lock (Automatic Transmission)
If you are parking on a hill and you do not shift the
automatic transmission into P (Park) 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 P (Park). This is called torque lock. To
prevent torque lock, set the parking brake and then shift
into P (Park) properly before you leave the driver’s seat.
To nd out how, see “Shifting Into P (Park)” previously in
the section.
When you are ready to drive, move the shift lever out of
P (Park) before releasing the parking brake.
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 P (Park).

Parking Over Things That Burn
{CAUTION:
Things that can burn could touch hot exhaust
parts under your vehicle and ignite. Do not
park over papers, leaves, dry grass, or other
things that can burn.
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.
CAUTION: (Continued)
CAUTION: (Continued)
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.
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.
Have your vehicle xed immediately.
2-48

Running the Vehicle 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 under
Engine Exhaust on page 2-48.
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.
Also see “If You Are Caught in a Blizzard”
underWinter Driving on page 4-17.
{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 (Automatic Transmission)
on page 2-45andParking the Vehicle (Manual
Transmission) on page 2-47.
If you are parking on a hill and if you are pulling a
trailer, seeTowing a Trailer on page 4-30.
