WARNING (Continued)
.Fuel can spray out if the fuel
cap is opened too quickly.
This spray can happen if the
tank is nearly full, and is
more likely in hot weather.
Open the fuel cap slowly and
wait for any hiss noise to stop
then unscrew the cap all
the way
The cap is behind a locking fuel
door on the passenger side of the
vehicle.
To open the fuel door, push the
rearward center edge in and release
and it will open.
To remove the tethered fuel cap,
turn it slowly counterclockwise.
While refueling, hang the tethered
fuel cap from the hook on the
fuel door.
If the fuel cap is not installed
properly, a message will appear on
the Driver Information Center
display. SeeFuel System Messages
on page 5‑36.
When reinstalling the cap, turn it
clockwise until it clicks once,
otherwise the malfunction indicator
lamp could turn on. See Malfunction
Indicator Lamp on page 5‑19. Be careful not to spill fuel. Do not
top off or overfill the tank and wait a
few seconds after you have finished
pumping before removing the
nozzle. Clean fuel from painted
surfaces as soon as possible. See
Exterior Care on page 10‑105.
When replacing the fuel cap, turn it
clockwise until it clicks once. Make
sure the cap is fully installed. The
diagnostic system can determine if
the fuel cap has been left off or
improperly installed. This would
allow fuel to evaporate into the
atmosphere. See
Malfunction
Indicator Lamp on page 5‑19.
{WARNING
If a fire starts while you are
refueling, do not remove the
nozzle. Shut off the flow of fuel by
shutting off the pump or by
notifying the station attendant.
Leave the area immediately.

certification mark indicates that the
oil has been approved to the dexos1
specification.
Notice:Failure to use the
recommended engine oil or
equivalent can result in engine
damage not covered by the
vehicle warranty. Check with your
dealer or service provider on
whether the oil is approved to the
dexos1 specification.
Viscosity Grade
SAE 5W-30 is the best viscosity
grade for the vehicle. Do not use
other viscosity grade oils such as
SAE 10W-30, 10W-40, or 20W-50.
Cold Temperature Operation: In an
area of extreme cold, where the
temperature falls below −29°C
(−20°F), an SAE 0W-30 oil may be used. An oil of this viscosity grade
will provide easier cold starting for
the engine at extremely low
temperatures. When selecting an oil
of the appropriate viscosity grade,
always select an oil of the correct
specification. See
“Specification”
earlier in this section.
Engine Oil Additives/Engine
Oil Flushes
Do not add anything to the oil. The
recommended oils with the dexos
specification and displaying the
dexos certification mark are all that
is needed for good performance and
engine protection.
Engine oil system flushes are not
recommended and could cause
engine damage not covered by the
vehicle warranty.
What to Do with Used Oil
Used engine oil contains certain
elements that can be unhealthy for
your skin and could even cause
cancer. Do not let used oil stay on
your skin for very long. Clean your skin and nails with soap and water,
or a good hand cleaner. Wash or
properly dispose of clothing or rags
containing used engine oil. See the
manufacturer's warnings about the
use and disposal of oil products.
Used oil can be a threat to the
environment. If you change your
own oil, be sure to drain all the oil
from the filter before disposal. Never
dispose of oil by putting it in the
trash or pouring it on the ground,
into sewers, or into streams or
bodies of water. Recycle it by taking
it to a place that collects used oil.
Engine Oil Life System
When to Change Engine Oil
This vehicle has a computer system
that indicates when to change the
engine oil and filter. This is based
on a combination of factors which
include engine revolutions, engine
temperature, and miles driven.
Based on driving conditions, the
mileage at which an oil change is
indicated can vary considerably. For
Black plate (12,1)Cadillac CTS/CTS-V Owner Manual - 2013 - crc2 - 8/22/12
10-12 Vehicle Care
the oil life system to work properly,
the system must be reset every time
the oil is changed.
When the system has calculated
that oil life has been diminished, it
indicates that an oil change is
necessary. A CHANGE ENGINE
OIL SOON message comes on. See
Engine Oil Messages on page 5‑35.
Change the oil as soon as possible
within the next 1 000 km (600 mi).
It is possible that, if driving under
the best conditions, the oil life
system might indicate that an oil
change is not necessary for up to a
year. The engine oil and filter must
be changed at least once a year
and at this time the system must be
reset. Your dealer has trained
service people who will perform this
work and reset the system. It is also
important to check the oil regularly
over the course of an oil drain
interval and keep it at the proper
level.
If the system is ever reset
accidentally, the oil must be
changed at 5 000 km (3,000 mi)since the last oil change.
Remember to reset the oil life
system whenever the oil is changed.
How to Reset the Engine Oil
Life System
Reset the system whenever the
engine oil is changed so that the
system can calculate the next
engine oil change. To reset the
system:
1. Using the DIC MENU button,
display OIL LIFE REMAINING
on the DIC. See Driver
Information Center (DIC) on
page 5‑27 andEngine Oil
Messages on page 5‑35.
2. Press the Set/Reset button and hold for two seconds to clear the
CHANGE ENGINE OIL SOON
message and reset the oil life
at 100%.
Be careful not to reset the oil life
display accidentally at any time
other than after the oil is changed. It cannot be reset
accurately until the next oil
change.
The oil life system can also be reset
as follows:
1. Turn the ignition on with the engine off.
2. Fully press and release the accelerator pedal three times
within five seconds.
If the CHANGE ENGINE OIL
SOON message is not on, the
system is reset.
The system is reset when the
CHANGE ENGINE OIL SOON
message is off.
If the CHANGE ENGINE OIL SOON
message comes back on when the
vehicle is started, the engine oil life
system has not been reset. Repeat
the procedure.

Notice:If the pressure cap is not
tightly installed, coolant loss and
possible engine damage may
occur. Be sure the cap is properly
and tightly secured.
If the coolant is not at the proper
level when the system cools down
again, see your dealer.
Engine Overheating
The vehicle has several indicators
to warn of engine overheating.
There are two engine hot messages
that may be displayed in the Driver
Information Center (DIC). See
Engine Cooling System Messages
on page 5‑34 for more information.
You may decide not to lift the hood
when one of these warnings appear,
but get service help right away. See
Roadside Service (U.S. and
Canada) on page 13‑7 orRoadside
Service (Mexico) on page 13‑9.
If you do decide to lift the hood,
make sure the vehicle is parked on
a level surface. Then check to see if the engine
cooling fans are running. If the
engine is overheating, the fan(s)
should be running. If they are not,
do not continue to run the engine
and have the vehicle serviced.
Notice:
Running the engine
without coolant may cause
damage or a fire. Vehicle damage
would not be covered by the
warranty. See Overheated Engine
Protection Operating Mode on
page 10‑22 for information on
driving to a safe place in an
emergency.
If Steam Is Coming from the
Engine Compartment
{WARNING
Steam from an overheated engine
can burn you badly, even if you
just open the hood. Stay away
from the engine if you see or hear
steam coming from it. Just turn it
(Continued)
WARNING (Continued)
off and get everyone away from
the vehicle until it cools down.
Wait until there is no sign of
steam or coolant before you open
the hood.
If you keep driving when the
engine is overheated, the liquids
in it can catch fire. You or others
could be badly burned. Stop the
engine if it overheats, and get out
of the vehicle until the engine
is cool.
If No Steam Is Coming from
the Engine Compartment
If an engine overheat warning is
displayed but no steam can be seen
or heard, the problem may not be
too serious. Sometimes the engine
can get a little too hot when the
vehicle:
.Climbs a long hill on a hot day.
.Stops after high-speed driving.
Black plate (22,1)Cadillac CTS/CTS-V Owner Manual - 2013 - crc2 - 8/22/12
10-22 Vehicle Care
.Idles for long periods in traffic.
.Tows a trailer.
If the overheat warning is displayed
with no sign of steam:
1. Turn the air conditioning off.
2. Turn the heater on to the highest temperature and to the highest
fan speed. Open the windows as
necessary.
3. In heavy traffic, let the engine idle in N (Neutral) while stopped.
If it is safe to do so, pull off the
road, shift to P (Park) or
N (Neutral) and let the
engine idle.
If the temperature overheat gauge is
no longer in the overheat zone or an
overheat warning no longer
displays, the vehicle can be driven.
Continue to drive the vehicle slow
for about 10 minutes. Keep a safe
vehicle distance from the car in front
of you. If the warning does not come
back on, continue to drive normally. If the warning continues, pull over,
stop, and park the vehicle
right away.
If there is no sign of steam, idle the
engine for three minutes while
parked. If the warning is still
displayed, turn off the engine until it
cools down. Also, see
“Overheated
Engine Protection Operating Mode”
next in this section.
Overheated Engine
Protection
Operating Mode
This operating mode allows the
vehicle to be driven to a safe place
in an emergency. Should a hot
engine condition exist, an overheat
protection mode which alternates
firing groups of cylinders helps
prevent engine damage. In this
mode, there is a loss in power and
engine performance. Driving
extended distances and/or towing a
trailer in the overheat protection
mode should be avoided.
Power Steering Fluid
See Engine Compartment Overview
on page 10‑5 for the location of the
power steering fluid reservoir.
When to Check Power Steering
Fluid
It is not necessary to regularly
check power steering fluid unless
you suspect there is a leak in the
system or you hear an unusual
noise. A fluid loss in this system
could indicate a problem. Have the
system inspected and repaired.
How to Check Power Steering
Fluid
To check the power steering fluid:
1. Turn the key off and let the engine compartment cool down.
