Boost Gauge

Metric

English
For the CTS-V, this gauge is located in the instrument panel cluster.
This gauge indicates positive manifold pressure, which is the induction air pressure level in the intake manifold before it enters the combustion chamber. This gauge reads zero under light throttle before boost is generated.
The gauge automatically resets to zero every time the engine is started.
