2007 CADILLAC DTS engine

A warning chime will sound if the parking brake is
set, the ignition is on, and the vehicle speed is
greater than 5 mph (8 km/h). The brake light
will come on and stay on until the parking brake is
released. SeeBrake System Warning Light on
page 229for more information.
To release the parking brake, hold the regular
brake pedal down with your right foot and push the
parking brake pedal down with your left foot.
When you lift your left foot, the parking brake pedal
will follow it to the released position.
Notice:Driving with the parking brake on can
overheat the brake system and cause
premature wear or damage to brake system
parts. Verify that the parking brake is fully
released and the brake warning light is
off before driving.
If you are towing a trailer and are parking on any
hill, seeTowing a Trailer on page 342.Shifting Into Park (P)
{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 342.

Leaving Your Vehicle With the Engine
Running
{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. SeeParking Brake on page 125for more
information.
Torque Lock
If you are parking on a hill and you do not shift your
transaxle into PARK (P) properly, the weight of the
vehicle may put too much force on the parking pawl
in the transaxle. 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, seeShifting
Into Park (P) on page 126.
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 transaxle, so you can pull the shift lever
out of PARK (P).

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.
130

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 130.
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 328.
{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. 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 the parking brake after you
move the shift lever to PARK (P).
Follow the proper steps to be sure your vehicle
will not move. SeeShifting Into Park (P) on
page 126.
If you are parking on a hill and if you are pulling a
trailer, also seeTowing a Trailer on page 342.

Cleaning the System
The radar can become blocked by snow, ice, or
dirt. If so, you may need to turn off the engine
and clean the lens. See “Cleaning the System”
underAdaptive Cruise Control on page 179.
Flash-to-Pass
This feature lets you use the high-beam
headlamps to signal the driver in front of
you that you want to pass.
The ash-to-pass feature will only work with the
headlamps on. It does not work with Daytime
Running Lamps (DRL).
Pull and hold the turn signal lever toward you
to use.
If the headlamps are on high beam, they will
switch to low beam. To return to high beam,
push the lever away from you.
Windshield Wipers
You control the windshield wipers by turning the
band with the wiper symbol on it.
8(Mist):Turn the band to mist for a single
wiping cycle. Hold it there until the wipers start.
Then let go. The wipers stop after one wipe.
For more wipe cycles, hold the band longer
on mist.
6(Delay):Turn the band to choose the delay time
between wipe cycles. The wiper speed can be set
for a long or short delay between wipes. The closer
the band is set to the top of the lever, the shorter
the delay.
6(Low Speed):Turn the band away from
you to the rst solid band past the delay settings
for steady wiping at low speed.
1(High Speed):For high-speed wiping, turn
the band further, to the second solid band past the
delay settings.
9(Off):To stop the wipers, move the band to off.

Using Adaptive Cruise Control on Hills
and When Towing a Trailer
How well Adaptive Cruise Control will work on hills
and when towing a trailer depends on your vehicle’s
speed, vehicle load, traffic conditions and the
steepness of the hills. It may not detect a vehicle
in your lane while driving on hills. When going up
steep hills, you may want to use the accelerator
pedal to maintain your vehicle’s speed. When going
downhill, especially when towing a trailer, you may
want to brake to keep your speed down. Applying
the brake disengages the system. You may choose
not to use Adaptive Cruise Control on steep hills,
especially when towing a trailer.
Disengaging Adaptive Cruise Control
To turn off the system, apply the brake pedal,
press the cancel button, or press the Adaptive
Cruise Control button.
Erasing Set Speed Memory
When you press the Adaptive Cruise Control
button or turn the ignition off, the set speed
memory is erased.
Other Messages
There are three additional messages that may
appear on the DIC. They are SERVICE RADAR
CRUISE, RADAR CRUISE NOT READY and
CLEAN RADAR. These messages will appear
to indicate a problem with the Adaptive Cruise
Control. SeeDIC Warnings and Messages
on page 246for more information.
Cleaning the System
The radar can become blocked by snow, ice, or
dirt. If so, you may need to turn off the engine and
clean the lens. Remember, do not use Adaptive
Cruise Control in icy conditions, or when visibility
is low, such as in fog, rain or snow.
The emblem/lens is located in the center of
the grille.
To clean the emblem/lens, wipe the surface with a
soft cloth. After cleaning the emblem/lens, try to
engage the Adaptive Cruise Control. If you
are unable to do so, see your dealer.
