Active Rev Match; Drive Systems; All-Wheel Drive - Cadillac CT4 2023 Owner's Manual

Caution
When downshifting, if more than one
gear is skipped, or the engine is racing
when the clutch pedal is released, the
engine, clutch, driveshaft or transmission
could be damaged.
No Lift-Shift
The vehicle can be shifted up a gear when
the accelerator pedal is pressed to the floor
without being released. This allows for less
power interruption and will improve
acceleration times. This feature is available
in all driver modes and is only active when
the engine speed is greater than:
Gears 1, 2 and 3 - above 3000 rpm
Gears 4 and 5 - above 2000 rpm

Active Rev Match

Vehicles equipped with a manual
transmission have Active Rev Match (ARM).
ARM aids in smoother shifting by matching
the engine speed to the next selected gear.
By monitoring shift lever and clutch
operation, ARM adjusts engine speed to
match a calibrated value based on gear
selection. On upshifts and downshifts,
engine speed will be increased and
decreased to match vehicle road speed and
transmission gear position. ARM is
maintained while the clutch pedal is pressed,
but will deactivate if the shift lever is left in
the Neutral position.
The system is activated and deactivated by
pressing the ARM switch on the center
console. The system must be activated with
each new ignition cycle. If ARM is
deactivated, the system will still perform rev
matching for upshifts.
A gear indicator in the instrument cluster
displays the current gear selected. ARM is
also shown in the Performance View of
the HUD:
Driving and Operating
When ARM is activated, the gear number
is amber.
When ARM is deactivated, the gear
number is white.
If no gear number is displayed while the
shift lever is in gear, service is required.
All rev matching will be disabled and the
malfunction indicator lamp will be on. See
Malfunction Indicator Lamp (Check Engine
Light) 0 92. The clutch and manual
transmission will continue to operate
normally.
ARM will also:
Be active above 28 km/h (18 mph).
Match engine speed up to 6100 rpm.
Not operate when the accelerator pedal is
applied.
Be disabled when the coolant
temperature is below 0 °C (32 °F).
