2007 CADILLAC STS V cruise control

Engaging Adaptive Cruise Control With
the Set Button
{CAUTION:
If you leave your Adaptive Cruise Control
switch on when you are not using cruise,
you might hit a button and go into cruise
when you do not want to. You could be
startled and even lose control. Keep the
Adaptive Cruise Control switch off until
you want to use cruise control.
{CAUTION:
If you operate Adaptive Cruise Control
without your Head-up Display (HUD)
properly adjusted, your Adaptive Cruise
Control settings may not be visible. You
could forget your settings and be startled
by Adaptive Cruise Control response and
even lose control. Keep your HUD on and
properly adjusted when using Adaptive
Cruise Control.
The set speed is selected by the driver. This is the
speed you will travel if there is no vehicle
detected in your path.

To set Adaptive Cruise Control, do the following:
1. Make sure the Head-Up Display (HUD) is
on and properly adjusted. You cannot
engage Adaptive Cruise Control unless the
HUD is on. SeeHead-Up Display (HUD)
on page 223for more information.
2. Move the switch to on.
3. Get up to the speed you want.
4. Press in the set button at the end of the lever
and release it.
5. Take your foot off the accelerator pedal.
Once Adaptive Cruise Control is set, it may
immediately apply the brakes if it detects a vehicle
ahead is too close or moving slower than your
vehicle.This symbol will
appear on the Head-Up
Display (HUD) to
indicate that Adaptive
Cruise Control is active.
The number indicates
the set speed.
SeeHead-Up Display (HUD) on page 223for
more information.
Make sure the set speed is visible on the HUD so
you know the speed your vehicle will accelerate to if
a vehicle is not detected in your path. Keep in mind
speed limits, surrounding traffic speeds and
weather conditions when adjusting your set speed.
If your vehicle is in Adaptive Cruise Control when
the traction control system begins to limit wheel
spin, the Adaptive Cruise Control will automatically
disengage. SeeTraction Control System (TCS) on
page 323andStabiliTrak
®System on page 326.
When road conditions allow you to safely use it
again, you may turn the Adaptive Cruise Control
back on.

Increasing Set Speed While Using Adaptive
Cruise Control
There are two ways to increase the set speed:
Use the accelerator to get to the higher speed.
Press the set button at the end of the lever,
then release the button and the accelerator
pedal. You will now cruise at the higher speed.
Move the Adaptive Cruise Control switch from
on to resume/increase. Hold it there until the
desired set speed is displayed in the HUD,
then release the switch. To increase your set
speed in very small amounts, move the
switch briey to resume/increase. Each time
you do this, your vehicle set speed will
increase by 1 mph (1.6 km/h).
Your vehicle will not reach the set speed until the
system determines there is not a vehicle in
front of you. At that point, your vehicle speed will
increase to the set speed.
Decreasing Set Speed While Using
Adaptive Cruise Control
Press in the set/decrease button on the end of the
lever until you reach the lower speed you want,
then release it.
To slow down in very small amounts, briey press
the set/decrease button. Each time you do this,
your set speed will be 1 mph (1.6 km/h) slower.
Resuming a Set Speed
Suppose you set your Adaptive Cruise Control at
a desired speed and then you apply the brake.
This will disengage the Adaptive Cruise Control.
But you do not need to reset it.
Once you are going about 25 mph (40 km/h) or
more, move the Adaptive Cruise Control
switch briey from on to resume/increase. Adaptive
Cruise Control will be engaged with the previously
chosen set speed.
202

Selecting the Follow Distance (GAP)
When the system detects a slower moving vehicle,
it will adjust your vehicle’s speed and maintain
the follow distance (gap) you select.
Use the GAP button on
the steering wheel to
adjust the follow
distance.
Press the top of the button to increase the
distance or the bottom of the button to decrease
the distance. The rst button press will show
you the current follow distance setting on the HUD.
Your current follow distance setting will be
maintained until you change it.
There are six follow distances to choose from. The
follow distance selection ranges from near to far
(one second to two seconds follow time). Thedistance maintained for a selected follow distance
will vary based on vehicle speed. The faster
the vehicle speed the further back you will follow.
Consider traffic and weather conditions when
selecting the follow distance. The range of
selectable distances may not be appropriate for all
drivers and driving conditions. If you prefer to
travel at a follow distance farther than Adaptive
Cruise Control allows, disengage the system
and drive manually.
A graphic on the HUD indicates the selected
follow distance. This picture shows a maximum
follow distance. The vehicles will move closer
together as you select a smaller follow distance.

Alerting the Driver
The alert symbol will
ash on the HUD and a
warning beep will
sound when driver
action is required.
Driver action is required when:
Adaptive Cruise Control cannot apply sufficient
braking because you are approaching a
vehicle too rapidly.
The vehicle speed drops below about
20 mph (32 km/h).
A temporary condition prohibits Adaptive
Cruise Control from operating. SeeDIC
Warnings and Messages on page 264for more
information.
A malfunction is detected in the system. See
DIC Warnings and Messages on page 264
for more information.
SeeDefensive Driving on page 316.
{CAUTION:
Adaptive Cruise Control has only limited
braking ability to slow your vehicle. In
some cases, Adaptive Cruise Control may
not have time to slow your vehicle enough
to avoid a collision. Be ready to take
action and apply the brakes yourself. See
Defensive Driving on page 316.
204

Approaching and Following a Vehicle
The vehicle ahead
symbol will only appear
on the HUD when a
vehicle ahead is
detected in your path.
If this symbol does not appear, or disappears
briey, Adaptive Cruise Control will not respond to
vehicles you may see ahead.
{CAUTION:
When the Adaptive Cruise Control radar is
blocked by snow, ice, or dirt, it may not
detect a vehicle ahead. Adaptive Cruise
Control may not have time to slow your
vehicle enough to avoid a collision.
CAUTION: (Continued)
CAUTION: (Continued)
Do not use Adaptive Cruise Control when
the radar is blocked by snow, ice, or dirt.
Keep your radar clean. See “Cleaning the
System” later in this section.
Adaptive Cruise Control will, automatically, slow
your vehicle down when approaching a slower
moving vehicle. It will then adjust your speed to
follow the vehicle in front at the selected follow
distance. Your speed will increase or decrease to
follow the vehicle in front of you but will not
exceed the set speed. It may apply limited braking,
if necessary. When braking is active, your brake
lights will come on. It may feel or sound different
than if you were applying the brakes yourself. This
is normal.
205

Stationary or Very Slow-Moving Objects
{CAUTION:
Adaptive Cruise Control may not detect
and react to stationary or slow-moving
vehicles or other objects ahead of you.
You could crash into an object ahead of
you. Do not use Adaptive Cruise Control
when approaching stationary or
slow-moving vehicles or other objects.
{CAUTION:
Adaptive Cruise Control may not detect
and react to stationary or slow-moving
vehicles or other objects ahead of you.
Your vehicle may accelerate toward
objects, such as a stopped vehicle that
suddenly appears after the lead vehicle
changes lanes. Your complete attention is
always required while driving and you
should be ready to take action and apply
the brakes.
206

Low-Speed Deactivation
If your speed falls below 20 mph (32 km/h) while
following a vehicle ahead, Adaptive Cruise Control
will begin to disengage. The driver alert symbol
on the HUD will ash and the warning beep
will sound. The driver must take action since
Adaptive Cruise Control will not slow the vehicle
to a stop.
Deactivation When Head-Up Display is
Turned Off
If you turn the HUD off when Adaptive Cruise
Control is engaged, it will begin to disengage. A
warning beep will sound and the message RADAR
CRUISE NOT READY will appear on the Driver
Information Center (DIC). SeeDIC Warnings
and Messages on page 264for additional
information. If Adaptive Cruise Control was braking
when the HUD is turned off, the braking will
continue briey.
Passing a Vehicle/Adaptive Cruise
Control Override
If you need to increase speed to pass a vehicle, use
the accelerator pedal. While you are doing this, the
system will not automatically apply the brakes. A
PEDAL APPLIED ACC OVERRIDE message will
appear on the HUD. SeeHead-Up Display (HUD)
on page 223for additional information. Once you
pass the vehicle and remove your foot from the
accelerator pedal, Adaptive Cruise Control will
return to normal operation and be able to apply the
brakes, if needed.
{CAUTION:
If you rest your foot on the accelerator
pedal, the system will not automatically
apply the brakes. You could crash into a
vehicle ahead of you. Do not rest your
foot on the accelerator pedal when using
Adaptive Cruise Control.
