transmission oil CADILLAC CTS V 2006 1.G Owners Manual

Starting the Engine
Automatic Transmission
Move your shift lever to PARK (P) or NEUTRAL (N).
Your engine will not start in any other position — that is
a safety feature. To restart when you are already
moving, use NEUTRAL (N) only.
Notice:Do not try to shift to PARK (P) if your
vehicle is moving. If you do, you could damage the
transmission. Shift to PARK (P) only when your
vehicle is stopped.
Manual Transmission
The shift lever should be in NEUTRAL and the parking
brake engaged. Hold the clutch pedal to the oor and
start the engine. Your vehicle will not start if the clutch
pedal is not all the way down — that is a safety feature.
1. With your foot off the accelerator pedal, turn your
ignition key to START. Then, let go of the key; the
engine will start automatically. The idle speed
will go down as your engine gets warm. Do not race
the engine immediately after starting it. Operate
the engine and transmission gently until the
oil warms up and lubricates all moving parts.Your vehicle has a Computer-Controlled Cranking
System. This feature assists in starting the
engine and protects the electrical system. If the
ignition key is turned to the START position,
and then released when the engine begins cranking,
the engine will continue cranking until the vehicle
starts or until it exceeds the maximum cranking time
allowed, approximately 15 seconds to prevent
cranking motor damage. To prevent starter-motor
gear damage, this system also prevents cranking if
the engine is already running. The engine cranking
can be stopped by turning the ignition switch to
the ACCESSORY or OFF position.
2. If your engine will not start, or starts but then stops,
it could be ooded with too much gasoline. Try
pushing your accelerator pedal all the way to the
oor and holding it there as you turn the key
to START. If the vehicle starts briey but then stops
again, do the same thing.
Notice:Your engine is designed to work with the
electronics in your vehicle. If you add electrical
parts or accessories, you could change the way the
engine operates. Before adding electrical equipment,
check with your dealer. If you do not, your engine
might not perform properly. Any resulting damage
would not be covered by your vehicle’s warranty.

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 4-9orTraction Control System
(TCS) (CTS-V) on page 4-10for more information.Speedometer Display
This display will show information relating to vehicle
speed, odometer, and transmission status. The
information displayed can be changed by pressing (C).
Pressing this button cycles the displayed information
as follows: digital speedometer only, odometer
only, speedometer and odometer, or blank display.
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 2-30.
Tachometer Display
Press (B) to cycle through the following displays:
coolant temperature, oil pressure, oil temperature,
transmission temperature, tire pressure, and lateral
acceleration. Press (A) to cycle through the displays in
reverse order. If you press (A), for about one second,
the display will become blank.

Transmission Fluid Hot Message
When you see this ashing
symbol, the transmission
uid temperature is
high (290°F (143°C)).
To acknowledge this warning, press either button on
the outboard switch on the left spoke of the steering
wheel. After you press this button, the warning will
redisplay every 10 minutes until the temperature
returns to the normal operating range. If this message
appears, you may continue to drive at a slower speed
while monitoring the transmission uid temperature.
Ideally, the transmission oil temperature should not rise
above 265°F (129°C). If you regularly experience
temperatures above this limit due to high performance
operation, it is recommended to use an auxiliary uid
cooler for the transmission and differential. See your
dealer for details. If this warning is displayed during
normal vehicle operation on at roads, your vehicle may
need service. See your dealer for an inspection. SeeDIC
Warnings and Messages on page 3-61andManual
Transmission Fluid on page 5-24for more information.
Hot Coolant Temperature
Warning Message
When you see this ashing
symbol, the engine coolant
temperature is high
(257°F (125°C)).
To acknowledge this warning, press either button on
the outboard switch on the left spoke of the steering
wheel. After you press a button, this warning will come
on every 10 minutes until the temperature returns to
the normal operating range. Driving aggressively
or driving on long hills can cause the engine coolant
temperature to be higher than normal. The Engine
Coolant Temperature Warning Light should also come
on. SeeEngine Coolant Temperature Warning Light
(CTS) on page 3-40for more information. If this warning
is displayed during normal vehicle operation on at
roads, your vehicle may need service. See your dealer
