oil dipstick CADILLAC CTS V 2004 1.G Owners Manual

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 driver’s side of the vehicle near the engine
oil dipstick. SeeEngine Compartment Overview
on page 5-12for more information on location.
You must 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 don’t, 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 in the area where you’ll be parking your
vehicle. The dealer can give you the best advice for that
particular area.
Automatic Transmission Operation
If your vehicle has an automatic transmission, the
shift lever is located on the center console between the
front seats.
There are several different positions for the shift lever.

Engine Oil
If the oil pressure light
and/or the Oil Pressure
Low - Stop Engine
message on the DIC
appears on the instrument
cluster, it means you
need to check your engine
oil level right away.
For more information, see “Oil Pressure Low - Stop
Engine” underDIC Warnings and Messages on
page 3-70andOil Pressure Light on page 3-49.
You should check your engine oil level regularly; this is
an added reminder.
Checking Engine Oil
It is a good idea to check your engine oil every time you
get fuel. In order to get an accurate reading, the oil
must be warm and the vehicle must be on level ground.
The engine oil dipstick handle is a yellow loop.
SeeEngine Compartment Overview on page 5-12
for the location of the engine oil dipstick.Turn off the engine and give the oil several minutes to
drain back into the oil pan. If you do not do this, the
oil dipstick might not show the actual level.
Pull out the dipstick and clean it with a paper towel or
cloth, then push it back in all the way. Remove it again,
keeping the tip down, and check the level.

When to Add Engine Oil
If the oil is at or below the lower mark for the 3.2L V6
engine or below the cross-hatched area at the tip of the
dipstick for the 3.6L V6 and 5.7L V8 engines, then
you will need to add at least one quart of oil. But you
must use the right kind. This section explains what kind
of oil to use. For engine oil crankcase capacity, see
Capacities and Specications on page 5-111.
Notice:Do not add too much oil. If your engine has
so much oil that the oil level gets above the upper
mark that shows the proper operating range,
your engine could be damaged.SeeEngine Compartment Overview on page 5-12
for the location of the engine oil ll cap.
Be sure to add enough oil to put the level somewhere
in the proper operating range. Push the dipstick all
the way back in when you are through. 5.7L V8 Engine
