Engine Speed Limiter; Engine Oil Pressure; Gauge - Cadillac CTS 2012 Owner's Manual

Cadillac CTS/CTS-V Owner Manual (Mid-East) - 2012
4-18 Instruments and Controls

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

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 4 29 for more information.
Black plate (18,1)
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 under Driver
Information Center (DIC) on
page 4 31 and Engine Oil on
page 9 9.
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 for changing engine oil.
