damage the transmission. The
repairs would not be covered by the
vehicle warranty. Shift to
R (Reverse) only after the vehicle is
stopped.
Caution
Do not rest your hand on the shift
lever while driving. The pressure
could cause premature wear in the
transmission. The repairs would not
be covered by the vehicle warranty.
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.

Cadillac CT4 Owner Manual (GMNA-Localizing-U.S./Canada-15283641) -
2022 - CRC - 10/12/21
DRIVING AND OPERATING 253
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:
.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)099. 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).
Drive Systems
All-Wheel Drive
Vehicles with this feature always send
engine power to all four wheels. It is
fully automatic, and adjusts itself as
needed for road conditions.
Brakes
Electric Brake Boost
Vehicles equipped with electric brake
boost have hydraulic brake circuits
that are electronically controlled when
the brake pedal is applied during
normal operation. The system
performs routine tests and turns off
within a few minutes after the vehicle
is turned off. Noise may be heard
during this time. If the brake pedal is
pressed during the tests or when the
electric brake boost system is off, a
noticeable change in pedal force and
travel may be felt. This is normal.
Antilock Brake
System (ABS)
The Antilock Brake System (ABS)
helps prevent a braking skid and
maintain steering while braking hard.

Cadillac CT4 Owner Manual (GMNA-Localizing-U.S./Canada-15283641) -
2022 - CRC - 10/12/21
254 DRIVING AND OPERATING
If there is a problem with ABS, this
warning light stays on. SeeAntilock
Brake System (ABS) Warning Light
0 102.
ABS does not change the time needed
to get a foot on the brake pedal and
does not always decrease stopping
distance. If you get too close to the
vehicle ahead, there will not be
enough time to apply the brakes if
that vehicle suddenly slows or stops.
Always leave enough room ahead to
stop, even with ABS.
Using ABS
Do not pump the brakes. Just hold the
brake pedal down firmly. Hearing and
feeling ABS operate is normal.
Braking in Emergencies
ABS allows steering and braking at the
same time. In many emergencies,
steering can help even more than
braking.
Electric Parking Brake
The Electric Parking Brake (EPB) can
always be applied, even if the vehicle
is off. In case of insufficient electrical
power, the EPB cannot be applied or
released. To prevent draining the
battery, avoid unnecessary repeated
cycles of the EPB.
The system has a red parking brake
status light and an amber service
parking brake warning light. See
Electric Parking Brake Light 0102 and
Service Electric Parking Brake Light
0 102. There are also parking
brake-related Driver Information
Center (DIC) messages. Before leaving the vehicle, check the
red parking brake status light to
ensure that the parking brake is
applied.
EPB Apply
To apply the EPB:
1. Be sure the vehicle is at a complete stop.
2. Press the EPB switch momentarily.
The red parking brake status light will
flash and then stay on once the EPB is
fully applied. If the red parking brake
status light flashes continuously, then
the EPB is only partially applied or
there is a problem with the EPB.
A DIC message will display. Release
the EPB and try to apply it again.
If the light does not come on, or keeps
flashing, have the vehicle serviced. Do
not drive the vehicle if the red parking
brake status light is flashing. See your
dealer.
If the amber service parking brake
warning light is on, press the EPB
switch. Continue to hold the switch
until the red parking brake status light
