1-22 In Brief
Tire Pressure Monitor
This vehicle may have a Tire
Pressure Monitor System (TPMS).
The TPMS warning light alerts you
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. SeeVehicle Load
Limits
on page 9‑11. The warning
light will remain on until the tire
pressure is corrected.
During cooler conditions, the low tire
pressure warning light may appear
when the vehicle is first started and
then turn off. This may be an early indicator that the tire pressures are
getting low and the tires need to be
inflated to the proper pressure.
The TPMS does not replace normal
monthly tire maintenance. It is the
driver
’s responsibility to maintain
correct tire pressures.
See Tire Pressure Monitor System
on page 10‑76.
Tire Sealant and
Compressor Kit
This vehicle may come with a jack
and spare tire or a tire sealant and
compressor kit. The kit can be used
to seal small punctures in the tread
area of the tire.
SeeTire Sealant and Compressor
Kit
on page 10‑92for complete
operating information.
If the vehicle came with a jack and
spare tire, see If a Tire Goes Flat
on
page 10‑90.
Engine Oil Life System
The engine oil life system calculates
engine oil life based on vehicle use
and displays the “Change Engine
Oil Soon” message when it is time
to change the engine oil and filter.
The oil life system should be reset
to 100% only following an oil
change.
Resetting the Oil Life System
1. Turn the ignition to ON/RUN with the engine off.
2. Fully press and release the accelerator pedal three times
within five seconds.

Engine Speed Limiter
This feature prevents the engine
speed from reaching an unsafe
level. If the level is too high, the
throttle closes or limits the fuel
supply until the engine speed
returns to a safe level. Throttle
operation and fuel supply return to
normal when engine speed is
lowered.
For the CTS-V, the tachometer
tracer lights flash prior to reaching
engine speed limit. The tracer lights
also flash on automatic transmission
vehicles while in the DSC or Tap
Shift modes.
Engine Oil Pressure
Gauge
English
Metric
For vehicles with an engine oil
pressure gauge, it shows the engine
oil pressure in kPa (kilopascals)
or psi (pounds per square inch)
when the engine is running.
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. See
Engine Oil Pressure Light
on
page 5‑26for more information.

Black plate (16,1)Cadillac CTS/CTS-V Owner Manual - 2011
5-16 Instruments and Controls
A reading outside the normal
operating range may be caused by
a dangerously low oil level or some
other problem causing low oil
pressure. Oil should be checked as
soon as possible. See Oil Pressure
Low Stop Engine underDriver
Information Center (DIC)
on
page 5‑27and Engine Oilon
page 10‑11.
{WARNING
Do not keep driving if the oil
pressure is low. The engine can
become so hot that it catches fire.
Someone could be burned. Check
the oil as soon as possible and
have the vehicle serviced.
Notice: Lack of proper engine oil
maintenance can 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 Coolant
Temperature Gauge
