Active Rev Match - Cadillac ATS 2017 Owner's Manual

236 DRIVING AND OPERATING
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
On ATS-V vehicles equipped with a
manual transmission, 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 vehicle
modes and is only active when the
engine speed is greater than 2500 rpm.

Active Rev Match

ATS-V 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 for a
few seconds between shifts, then
deactivates if the shift is not
completed.
The system is activated and
deactivated by pressing either of the
paddles on the steering wheel. The
system must be activated with each
new ignition cycle.
A gear indicator in the instrument
cluster displays the current gear
selected. ARM is also shown in the
Performance View of the HUD:
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. ARM will be
disabled, and the malfunction
indicator lamp will be on. See
Malfunction Indicator Lamp (Check
Engine Light) 0 121. The clutch and
manual transmission will continue
to operate normally.
ARM will also:
Be active above 14 km/h (9 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).
