2005 CADILLAC CTS transmission

Reducing Speed While Using Cruise
Control
There are two ways to reduce your speed while using
cruise control:
Press in the button at 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 button. Each time you do this, you’ll go
about 1 mph (1.6 km/h) slower.
Passing Another Vehicle While Using
Cruise Control
Use the accelerator pedal to increase your speed.
When you take your foot off the pedal, your vehicle will
slow down to the cruise control speed you set earlier.
Using Cruise Control on Hills
How well your cruise control will work on hills depends
upon your speed, load and the steepness of the
hills. When going up steep hills, you may have to step
on the accelerator pedal to maintain your speed.
When going downhill, you may have to brake or shift to
a lower gear to keep your speed down. Applying the
brake or shifting into a lower gear will take you out
of cruise control. If you need to apply the brake or shift
to a lower gear due to the grade of the downhill
slope, you may not want to attempt to use your cruise
control feature.
Ending Cruise Control
To end a cruise control session, step lightly on the
brake pedal. If your vehicle has a manual transmission,
lightly tapping the clutch will end a cruise control
session also.
Stepping on the brake or clutch pedal will end the
current cruise control session only. Move the cruise
control switch to off to turn off the system completely.
Erasing Speed Memory
When you turn off the cruise control or the ignition, your
cruise control set speed memory is erased.

Headlamps on Reminder
A warning chime will sound if the exterior lamp control
is left on in either the headlamp or parking lamp position
and the driver’s door is opened with the ignition off.
SeeLights On Reminder on page 3-49for additional
information.
Daytime Running Lamps (DRL)
Daytime Running Lamps (DRL) can make it easier for
others to see the front of your vehicle during the
day. DRL can be helpful in many different driving
conditions, but they can be especially helpful in the short
periods after dawn and before sunset. Fully functional
daytime running lamps are required on all vehicles
rst sold in Canada.
The DRL system will make the turn signal lamps come
on when the following conditions are met:
It is still daylight and the ignition is in ON
or START,
the exterior lamp control is in off or AUTO with the
headlamps off, and
an automatic transmission is not in PARK (P) or the
parking brake is not set on a manual transmission.When DRL are on, only your front turn signal lamps will
be on. No other exterior lamps will be on when the
DRL are being used. Your instrument panel won’t be lit
up either.
When the exterior lamp control is in AUTO and it’s dark
enough outside, the DRL will turn off and the low-beam
headlamps will turn on. When it’s bright enough
outside, the low-beam headlamps will go off, and the
DRL will turn back on. If you start your vehicle in a dark
garage, the automatic headlamp system will come on
immediately. Once you leave the garage, it will take
about one minute for the automatic headlamp system to
change to DRL if it is light outside. During that delay,
your instrument panel cluster may not be as bright
as usual. Make sure your instrument panel brightness
lever is in the full bright position. SeeInstrument
Panel Brightness on page 3-24.

Malfunction Indicator Lamp
Check Engine Light
Your vehicle is equipped
with a computer which
monitors operation of the
fuel, ignition, and emission
control systems.
This system is called OBD II (On-Board
Diagnostics-Second Generation) and is intended to
assure that emissions are at acceptable levels for the
life of the vehicle, helping to produce a cleaner
environment. The check engine light comes on to
indicate that there is a problem and service is required.
Malfunctions often will be indicated by the system
before any problem is apparent. This may prevent more
serious damage to your vehicle. This system is also
designed to assist your service technician in correctly
diagnosing any malfunction.Notice:If you keep driving your vehicle with this
light on, after awhile, your emission controls
may not work as well, your fuel economy may not
be as good, and your engine may not run as
smoothly. This could lead to costly repairs that may
not be covered by your warranty.
Notice:Modications made to the engine,
transmission, exhaust, intake, or fuel system of
your vehicle or the replacement of the original tires
with other than those of the same Tire Performance
Criteria (TPC) can affect your vehicle’s emission
controls and may cause this light to come on.
Modications to these systems could lead to costly
repairs not covered by your warranty. This may
also result in a failure to pass a required Emission
Inspection/Maintenance test.

Oil Pressure Light
{CAUTION:
Do not keep driving if the oil pressure is low. If
you do, your engine can become so hot that it
catches re. You or others could be burned.
Check your oil as soon as possible and have
your vehicle serviced.
Notice:Lack of proper engine oil maintenance may
damage the engine. The repairs would not be
covered by your warranty. Always follow the
maintenance schedule in this manual for changing
engine oil.
This light tells you if there
could be a problem with
your engine oil pressure.The light goes on when you turn your key to ON or
START. It goes off once you start your engine. That’s a
check to be sure the light works. If it doesn’t come
on, be sure to have it xed so it will be there to warn
you if something goes wrong.
When the light comes on and stays on, it means that oil
isn’t owing through your engine properly. You could
be low on oil and you might have some other system
problem. SeeEngine Oil on page 5-16for more
information.

Here are a few concerns some owners have had about
the fuel gage. All of these situations are normal and
do not indicate that anything is wrong with the fuel gage:
At the gas station the gas pump shuts off before
the gage reads full.
The gage may change when you turn, stop quickly
or accelerate quickly.
It takes a little more or less fuel to ll the tank than
the gage indicated. For example, the gage may
have indicated that the tank was half full, but
it actually took a little more or less than half the
tank’s capacity to ll the tank.
Message Center
Message Center (CTS-V)
Your vehicle may have a message center that can
display information relating to powertrain uids,
tire pressures, vehicle dynamics, speedometer and
odometer information, and transmission status. It also
displays warning messages. There are two different
areas where message center information will be
displayed. One display is inside of the tachometer and
the other is inside of the speedometer.These are the controls
for the message center.
They are located on
the left spoke of the
steering wheel.
The outboard switch (A and B) controls the display of
information inside of the tachometer. The upper
button (C) on the inboard switch controls the display of
information inside of the speedometer. The lower
button (D) on the inboard switch turns the traction
control on or off. SeeTraction Control System (TCS)
(CTS) on page 4-8orTraction Control System
(TCS) (CTS-V) on page 4-9for more information.

When the transmission is shifted into REVERSE (R), an
R will appear in the upper right corner.
During slow speed maneuvers, the engine’s computer
may command the transmission to engage the Skip Shift
feature. For more information seeManual Transmission
Operation on page 2-31.
Tachometer Display
Press (B) to cycle through the following displays:
coolant temperature, oil pressure, oil temperature,
