Tire Pressure Monitor
This vehicle may have a Tire
Pressure Monitor System (TPMS).
The low tire pressure warning light
alerts to a significant loss in
pressure of one of the vehicle's
tires. If the warning light comes on,
stop as soon as possible and inflate
the tires to the recommended
pressure shown on the Tire and
Loading Information label. See
Vehicle Load Limits on page 9‑10.
The warning light will remain on until
the tire pressure is corrected.
The low tire pressure warning light
may come on in cool weather when
the vehicle is first started, and then
turn off as the vehicle is driven. This
may be an early indicator that thetire pressures are getting low and
the tires need to be inflated to the
proper pressure.
The TPMS does not replace normal
monthly tire maintenance. Maintain
the correct tire pressures.
See
Tire Pressure Monitor System
on page 10‑68.
Tire Sealant and
Compressor Kit
This vehicle may come with a spare
tire and tire changing equipment or
a tire sealant and compressor kit.
The kit can be used to temporarily
seal small punctures in the tread
area of the tire. See Tire Sealant
and Compressor Kit on page 10‑82.
If the vehicle came with a spare tire
and tire changing equipment, see If
a Tire Goes Flat on page 10‑80.

9-6 Driving and Operating
CTS‐V Only: Be sure to check the
oil level often during racing, track
testing or other competitive driving
and keep the level at or near the
upper mark that shows the proper
operating range on the engine oil
dipstick.
For competitive driving, it is
recommended that the brake fluid
be replaced with a high performance
brake fluid that has a dry boiling
point greater than 279°C (534°F).
After conversion to the high
performance brake fluid, follow the
brake fluid service
recommendations outlined by the
fluid manufacturer. Do not use
silicone or DOT‐5 brake fluids.
HF V6 Engine Only: Be sure to
check the oil level often during
racing, track testing or other
competitive driving and keep the
level at or near 0.5 L (0.5 qt) above
the upper mark that shows the
proper operating range on the
engine oil dipstick. For racing, tracktesting or other competitive driving
an engine oil cooler must be
installed.
Driving on Wet Roads
Rain and wet roads can reduce
vehicle traction and affect your
ability to stop and accelerate.
Always drive slower in these types
of driving conditions and avoid
driving through large puddles and
deep‐standing or flowing water.
{WARNING
Wet brakes can cause crashes.
They might not work as well in a
quick stop and could cause
pulling to one side. You could
lose control of the vehicle.
After driving through a large
puddle of water or a car/vehicle
wash, lightly apply the brake
pedal until the brakes work
normally.
(Continued)
WARNING (Continued)
Flowing or rushing water creates
strong forces. Driving through
flowing water could cause the
vehicle to be carried away. If this
happens, you and other vehicle
occupants could drown. Do not
ignore police warnings and be
very cautious about trying to drive
through flowing water.
Hydroplaning
Hydroplaning is dangerous. Water
can build up under the vehicle's
tires so they actually ride on the
water. This can happen if the road is
wet enough and you are going fast
enough. When the vehicle is
hydroplaning, it has little or no
contact with the road.
There is no hard and fast rule about
hydroplaning. The best advice is to
slow down when the road is wet.

Driving and Operating 9-15
manual transmission, shift to the
next lower gear. This rule
applies at all times, not just
during the break-in period.
.Do not participate in track
events, sport driving schools,
or similar activities during this
break–in period.
.Check engine oil with every
refueling and add if necessary.
Oil and fuel consumption may be
higher than normal during the
first 2 414 km (1,500 miles).
.To break in new tires, drive at
moderate speeds and avoid hard
cornering for the first
322 km (200 miles). New tires do
not have maximum traction and
may tend to slip.
.New brake linings also need a
break–in period. Avoid making
hard stops during the first
322 km (200 miles). This is
recommended every time brake
linings are replaced.
Ignition Positions
(Keyless Access)
The ignition control knob can be
turned to four different positions.
To shift out of P (Park), the ignition
must be in ON/RUN or ACC/
ACCESSORY and the regular brake
pedal must be applied.
Using a tool to force the ignition
control knob from its cylinder could
damage it.Make sure the keyless access
transmitter is inside the vehicle
when trying to turn the ignition
control knob.
1 (STOPPING THE ENGINE/LOCK/
OFF):
When the vehicle is stopped,
turn the ignition switch to LOCK/
OFF to turn the engine off. Retained
Accessory Power (RAP) will remain
active. See Retained Accessory
Power (RAP) on page 9‑21.
The ignition control knob cannot be
removed from the vehicle. The
keyless access transmitter must be
inside the vehicle to start the
engine. This position locks the
ignition and shift lever on automatic
transmission vehicles, and the
ignition and steering wheel on
manual transmission vehicles.
Do not turn the engine off when the
vehicle is moving. This will cause a
loss of power assist in the brake
and steering systems and disable
the airbags.

9-48 Driving and Operating
when using gasoline rated at
91 octane or higher, the engine
needs service.
Gasoline Specifications
At a minimum, gasoline should meet
ASTM specification D 4814. Some
gasolines contain an
octane-enhancing additive called
methylcyclopentadienyl manganese
tricarbonyl (MMT). We recommend
against the use of gasolines
containing MMT. SeeFuel Additives
on page 9‑48.
California Fuel
Requirements
If the vehicle is certified to meet
California Emissions Standards, it is
designed to operate on fuels that
meet California specifications. See
the underhood emission control
label. If this fuel is not available in
states adopting California Emissions
Standards, the vehicle will operate
satisfactorily on fuels meeting
federal specifications, but emission control system performance might
be affected. The malfunction
indicator lamp could turn on and the
vehicle might fail a smog‐check test.
See
Malfunction Indicator Lamp on
page 5‑19. If this occurs, return to
your authorized dealer for diagnosis.
If it is determined that the condition
is caused by the type of fuel used,
repairs might not be covered by the
vehicle warranty.
Fuels in Foreign
Countries
Never use leaded gasoline or any
other fuel not recommended in the
previous text on fuel. Costly repairs
caused by use of improper fuel
would not be covered by the vehicle
warranty.
To check the fuel availability, ask an
auto club, or contact a major oil
company that does business in the
country where you will be driving.
Fuel Additives
To provide cleaner air, all gasolines
in the United States are now
required to contain additives that
help prevent engine and fuel system
deposits from forming, allowing the
emission control system to work
properly. In most cases, nothing
should have to be added to the fuel.
However, some gasolines contain
only the minimum amount of
additive required to meet U.S.
Environmental Protection Agency
regulations. To help keep fuel
injectors and intake valves clean
and avoid problems due to dirty
injectors or valves, look for gasoline
that is advertised as TOP TIER
Detergent Gasoline. Look for the
TOP TIER label on the fuel pump to
ensure gasoline meets enhanced
detergency standards developed by
the auto companies. A list of
marketers providing TOP TIER
Detergent Gasoline can be found at
www.toptiergas.com.

Black plate (49,1)Cadillac CTS/CTS-V Owner Manual - 2013 - crc2 - 8/22/12
Driving and Operating 9-49
For customers who do not use TOP
TIER Detergent Gasoline regularly,
one bottle of GM Fuel System
Treatment PLUS, added to the fuel
tank at every engine oil change, can
help clean deposits from fuel
injectors and intake valves. GM Fuel
System Treatment PLUS is the only
gasoline additive recommended by
General Motors. It is available at
your dealer.
Gasolines containing oxygenates,
such as ethers and ethanol, and
reformulated gasolines might be
available in your area. We
recommend that you use these
gasolines, if they comply with the
specifications described earlier.
However, E85 (85% ethanol) and
other fuels containing more than
15% ethanol must not be used in
vehicles that were not designed for
those fuels.
Notice:This vehicle was not
designed for fuel that contains
methanol. Do not use fuel
containing methanol. It can
corrode metal parts in the fuel system and also damage plastic
and rubber parts. That damage
would not be covered under the
vehicle warranty.
Some gasolines that are not
reformulated for low emissions can
contain an octane-enhancing
additive called
methylcyclopentadienyl manganese
tricarbonyl (MMT); ask the attendant
where you buy gasoline whether the
fuel contains MMT. We recommend
against the use of such gasolines.
Fuels containing MMT can reduce
spark plug life and affect emission
control system performance. The
malfunction indicator lamp might
turn on. If this occurs, return to your
dealer for service.Filling the Tank
{WARNING
Fuel vapors and fuel fires burn
violently and can cause injury or
death.
.To help avoid injuries to you
and others, read and follow
all the instructions on the fuel
pump island.
.Turn off the engine when
refueling.
.Keep sparks, flames, and
smoking materials away
from fuel.
.Do not leave the fuel pump
unattended.
.Do not reenter the vehicle
while pumping fuel.
.Keep children away from the
fuel pump and never let
children pump fuel.

10-10 Vehicle Care
Checking Engine Oil
It is a good idea to check the engine
oil level at each fuel fill. In order to
get an accurate reading, the vehicle
must be on level ground. The
engine oil dipstick handle is a loop.
SeeEngine Compartment Overview
on page 10‑5 for the location of the
engine oil dipstick.
1. If the engine has been running recently, turn off the engine and
allow several minutes for the oil
to drain back into the oil pan.
Checking the oil level too soon
after engine shutoff will not
provide an accurate oil level
reading.
{WARNING
The engine oil dipstick handle
may be hot; it could burn you.
Use a towel or glove to touch the
dipstick handle. 2. 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 below the cross-hatched
area at the tip of the dipstick, add
1 L (1 qt) of the recommended oil
and then recheck the level. See
“Selecting the Right Engine Oil” in
this section for an explanation of
what kind of oil to use. For engine
oil crankcase capacity, see
Capacities and Specifications on
page 12‑2.
Notice: Do not add too much oil.
Oil levels above or below the
acceptable operating range
shown on the dipstick are harmful
to the engine. If you find that you
have an oil level above the
operating range, i.e., the engine
has so much oil that the oil level
gets above the cross-hatched
area that shows the proper
operating range, the engine could be damaged. You should drain
out the excess oil or limit driving
of the vehicle and seek a service
professional to remove the
excess amount of oil.
See
Engine Compartment Overview
on page 10‑5 for the location of the
engine oil fill cap.
Add enough oil to put the level
somewhere in the proper operating
range. Push the dipstick all the way
back in when through.
Selecting the Right Engine Oil
Selecting the right engine oil
depends on both the proper oil
specification and viscosity grade.
See Recommended Fluids and
Lubricants on page 11‑13.
Specification
Use and ask for licensed engine oils
with the dexos1
®approved
certification mark. Engine oils
meeting the requirements for the
vehicle should have the dexos1
approved certification mark. This

Black plate (11,1)Cadillac CTS/CTS-V Owner Manual - 2013 - crc2 - 8/22/12
Vehicle Care 10-11
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
