2008 CADILLAC CTS engine oil

If the vehicle is left running it automatically shuts off
after 10 minutes unless a time extension has been done.
To manually shut off a remote start:
Aim the transmitter at the vehicle and press
the remote start button until the parking lamps
turn off.
Turn on the hazard warning ashers.
Turn the ignition switch on and then off.
The remote vehicle start feature provides two separate
starts, each with 10 minutes of engine running, or it
provides one start with 10 minutes of engine running
that may be extended 10 more minutes. If the transmitter
lock button is pressed and released and then the remote
start button is pressed and held again before the rst
10 minutes of engine running time has expired,
10 minutes are added to the remaining minutes.
For example, if the lock button and then the remote
start buttons are pressed again after ve minutes of
the engine run time, 10 minutes are added and you
now have 15 minutes of engine running. The added
ten minutes are considered a second remote vehicle
start.
Once two remote starts or a single start with a time
extension have been used, the vehicle must be started
with the keyless access ignition control knob before
the remote start feature can be used again.The remote start feature does not operate if any of the
following occur:
The ignition is in any position other than LOCK/OFF.
A keyless access transmitter is inside the vehicle.
The hood is open.
There is an emission control system malfunction.
The remote start feature is not enabled.
See “Remote Start” underDIC Vehicle
Customization on page 3-69.
The engine turns off during a remote vehicle start if the
coolant temperature gets too high, or the oil pressure
is too low.
This vehicle was shipped from the factory with the
remote vehicle start system enabled. The system may
be disabled through the Driver Information Center (DIC).
See “Remote Start” underDIC Vehicle Customization
on page 3-69for additional information.
SeeEngine Exhaust on page 2-48for important safety
information when using remote start in a closed garage.

Manual Transmission
The shift lever should be in neutral position and the
parking brake engaged. Hold the clutch pedal down
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.
Starting Procedure
1. With your foot off the accelerator pedal, turn the
ignition key to START. If your vehicle has the keyless
access system, make sure there is a keyless access
transmitter in the vehicle. When the engine starts,
let go of the ignition. 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 to allow the oil to warm up and
lubricate all moving parts.
Your vehicle has a Computer-Controlled Cranking
System. This feature assists in starting the engine
and protects components. If the ignition key is turned
to the START position, and then released when the
engine begins cranking, the engine will continue
cranking for a few seconds or until the vehicle starts.
If the engine does not start and the key is held in
START for many seconds, cranking will be stopped
after 15 seconds to prevent cranking motor damage.
To prevent gear damage, this system also prevents
cranking if the engine is already running. Engine
cranking can be stopped by turning the ignition
switch to ACC/ACCESSORY or LOCK/OFF.Notice:Cranking the engine for long periods of
time, by returning the key to the START position
immediately after cranking has ended, can overheat
and damage the cranking motor, and drain the
battery. Wait at least 15 seconds between each try,
to let the cranking motor cool down.
2. If the engine does not start after 5-10 seconds,
especially in very cold weather (below 0°F or−18°C),
it could be ooded with too much gasoline. Try
pushing the accelerator pedal all the way to the oor
and holding it there as you hold the key in START
for up to a maximum of 15 seconds. Wait at least
15 seconds between each try, to allow the cranking
motor to cool down. When the engine starts, let go of
the key and accelerator. If the vehicle starts briey
but then stops again, do the same thing. This clears
the extra gasoline from the engine. 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.
Notice:The engine is designed to work with the
electronics in the vehicle. If you add electrical parts
or accessories, you could change the way the
engine operates. Before adding electrical equipment,
check with your dealer/retailer. If you do not, the
engine might not perform properly. Any resulting
damage would not be covered by the vehicle
warranty.

Engine Coolant Heater
The engine coolant heater, if available, can help in cold
weather conditions at or below 0°F (−18°C) for easier
starting and better fuel economy during engine warm-up.
Plug in the coolant heater at least four hours before
starting your vehicle. An internal thermostat in the
plug-end of the cord may exist which will prevent
engine coolant heater operation at temperatures
above 0°F (−18°C).
To Use the Engine Coolant Heater
1. Turn off the engine.
2. Open the hood and unwrap the electrical cord.
The cord is located in the engine compartment
on the passenger side of the vehicle in front of
the fuse block.
Remove the plastic cap to access the plug.
3. Plug it into a normal, grounded 110-volt AC outlet.
{CAUTION:
Plugging the cord into an ungrounded outlet
could cause an electrical shock. Also, the
wrong kind of extension cord could overheat
and cause a re. You could be seriously
injured. Plug the cord into a properly grounded
three-prong 110-volt AC outlet. If the cord will
not reach, use a heavy-duty three-prong
extension cord rated for at least 15 amps.
4. Before starting the engine, be sure to unplug and
store the cord as it was before to keep it away
from moving engine parts. If you do not, it could
be damaged.
How long should you keep the coolant heater plugged
in? The answer depends on the outside temperature, the
kind of oil you have, and some other things. Instead of
trying to list everything here, we ask that you contact your
dealer/retailer in the area where you will be parking your
vehicle. The dealer/retailer can give you the best advice
for that particular area.

Oil Pressure Light
Your vehicle may have this
feature.
If the vehicle has an oil problem, this light may stay on
after the engine is started, or come on while you are
driving.
This light indicates that oil is not going through the
engine quickly enough to keep it lubricated. The engine
could be low on oil or could have some other oil
problem. Have it xed right away.The oil light could also come on in the following
situations:The light will come on briey when the ignition is
turned on to show that it is working properly. If it
does not come on with the ignition on, there may
be a problem with the fuse or bulb. Have it
xed right away.
Sometimes when the engine is idling at a stop, a
chime will sound and the light may blink on and
off. This is normal.
{CAUTION:
Do not keep driving if the oil pressure is low.
The engine can become so hot that it catches
re. You or others could be burned. Check the
oil as soon as possible and have the vehicle
serviced.
Notice:Lack of proper engine oil maintenance may
damage the engine. The repairs would not be
covered by the vehicle warranty. Always follow the
maintenance schedule in this manual for changing
engine oil.

Engine Oil Pressure Gage
Your vehicle may have an engine oil pressure gage.
It shows the engine oil pressure in psi (pounds per
square inch) when the engine is running. Canadian
vehicles indicate pressure in kPa (kilopascals).
Oil pressure may vary with engine speed, outside
temperature and oil viscosity, but if readings are outside
the normal operating range, the oil pressure light will
come on. SeeOil Pressure Light on page 3-44for more
information.A reading outside the normal operating range may be
caused by a dangerously low oil level or some other
problem causing low oil pressure. Check your oil as
soon as possible. See Oil pressure Low Stop Engine
underDIC Warnings and Messages on page 3-56
andEngine Oil on page 5-16.
{CAUTION:
Do not keep driving if the oil pressure is low.
