2005 Cadillac CTS/CTS-V Owner ManualM

Vehicle Damage Warnings
Also, in this manual you will nd these notices:
Notice:These mean there is something that could
damage your vehicle.
A notice tells about something that can damage the
vehicle. Many times, this damage would not be covered
by your vehicle’s warranty, and it could be costly. But
the notice will tell what to do to help avoid the damage.
When you read other manuals, you might see
CAUTION and NOTICE warnings in different colors
or in different words.
There are also warning labels on the vehicle. They use
the same words, CAUTION or NOTICE.
Vehicle Symbols
The vehicle has components and labels that use
symbols instead of text. Symbols are shown along with
the text describing the operation or information
relating to a specic component, control, message,
gage, or indicator.
If you need help guring out a specic name of a
component, gage, or indicator, reference the following
topics:
Seats and Restraint Systems in Section 1
Features and Controls in Section 2
Instrument Panel Overview in Section 3

Power Lumbar
Your vehicle may have this feature. The driver’s and
passenger’s seatback lumbar support can be adjusted
by moving a control located on the outboard side of
the seat cushions.
To increase or decrease support, hold the control
forward or rearward. Keep in mind that as your seating
position changes, as it may during long trips, so
should the position of your lumbar support. Adjust the
seat as needed.
Heated Seats
If your vehicle is equipped
with heated front seats, the
buttons are located on
the climate control panel.There is one button for the driver and one for the front
passenger. Each button has three settings, LO, HI
and off. The active setting appears on the climate control
panel display. The LO setting warms the seatback
and cushion until the seat approximates normal body
temperature. The HI setting has a slightly higher
temperature.
To turn on the heated seats, press the button once. The
seat will heat to the HI setting. Press the button again
to switch to the LO setting. Pressing the button a
third time turns the system off.
The heated seats can only be used when the ignition is
turned on. When the vehicle is turned off, the heated
seats automatically turn off. If you wish to have the
heated seats on once the vehicle is restarted, press the
button again.
1-3

When you want to open a rear door when the security
lock is on, do the following:
1. Unlock the door using the remote keyless entry
transmitter, the front door power lock switch or
by lifting the rear door manual lock.
2. Then open the door from the outside.
To cancel the rear door security lock, do the following:
1. Unlock the door and open it from the outside.
2. Insert your key into the slot next to the rear door
security lock label and turn it to disengage the lock.
3. Repeat the steps for the other lock.
The rear door locks will now work normally.
Lockout Protection
If you press the power door lock switch when the key is
in the ignition and any door is open, all the doors will
lock and only the driver’s door will unlock. If you
close the doors, you can lock them using the remote
keyless entry transmitter. Be sure to remove the
key from the ignition when locking your vehicle.
This feature can be overridden by pressing the lock
button on the remote keyless entry transmitter or
by pressing the power lock switch a second time.
Trunk
{CAUTION:
It can be dangerous to drive with the trunk lid
open because carbon monoxide (CO) gas can
come into your vehicle. You cannot see or
smell CO. It can cause unconsciousness and
even death. If you must drive with the trunk lid
open or if electrical wiring or other cable
connections must pass through the seal
between the body and the trunk lid:
Make sure all other windows are shut.
Turn the fan on your heating or cooling
system to its highest speed and select the
control setting that will force outside air
into your vehicle. See Climate Control
System in the Index.
If you have air outlets on or under the
instrument panel, open them all the way.
SeeEngine Exhaust on page 2-38.
2-11

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:
Your 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 exhaust system had 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.
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 under
Engine Exhaust on page 2-38.
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 4-28.

Outside Curb View Assist Mirror
If the vehicle has the memory seat and mirrors, it will be
capable of adjusting the passenger’s mirror to tilt to a
preselected position when the vehicle is shifted into
REVERSE (R). Use this outside curb view assist feature
to view the curb when parallel parking.
When the vehicle is shifted out of REVERSE (R) and
after a ve-second delay, the passenger’s mirror
will return to its original position.
If further adjustment is needed after the mirror is tilted,
the mirror controls can be used. SeeOutside Power
Mirrors on page 2-42for more information.
The outside curb view assist can be turned or off
through the Driver Information Center (DIC). SeeDIC
Vehicle Personalization on page 3-74for more
information.
Outside Convex Mirror
{CAUTION:
A convex mirror can make things (like other
vehicles) look farther away than they really are.
If you cut too sharply into the right lane, you
could hit a vehicle on your right. Check your
inside mirror or glance over your shoulder
before changing lanes.
The passenger’s side mirror is convex. A convex
mirror’s surface is curved so that more can be seen
from the driver’s seat. The mirror does not have
a dimming feature.
Outside Heated Mirrors
When the rear window defogger is turned on, it also
warms both outside rearview mirrors to help clear them
of fog or ice. See “Rear Window Defogger” under
Dual Climate Control System on page 3-27for more
information.
