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.

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
Metric
English
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 5‑25 for 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. Oil should be checked as
soon as possible. See Oil Pressure
Low Stop Engine underEngine Oil
Messages on page 5‑35 andEngine
Oil on page 10‑9.
Notice: Lack of proper engine oil
maintenance can damage the
