3. Press the controls on the back ofthe steering wheel to shift. Use
the left steering wheel control to
downshift, and the right control
to upshift. To shift to the lowest
available gear, press and hold the
left control.
To exit Permanent Tap Shift Mode: 1. To exit M (Manual Mode) and return to D (Drive), pull back on
the shift lever. The D in the shift
pattern will illuminate in red,
and the M will switch to white.
2. After releasing the shift lever, it will return to the center position.
M (Manual Mode) can be exited to
return to D (Drive) at any speed by
pulling the lever rearward from the
center position. It is not necessary to
stop the vehicle or shift to N (Neutral)
or P (Park) prior to shifting back to
D (Drive).
Temporary Tap Manual Shift Mode
To enter Temporary Tap Shift Mode: 1. With the transmission in D (Drive) and not in Permanent
Tap Shift Mode, the Tap Shift controls will activate a
temporary tap manual shift
mode, allowing the transmission
to be manually shifted.
2. To shift to the lowest available gear, press and hold the left
control.
3. To deactivate, hold the right control briefly. Automatic shifts
return after no manual shifts
have been done for seven to
10 seconds.
While using Tap Shift, the vehicle will
have firmer, quicker shifting. This can
be used for sport driving or when
climbing or descending hills, to stay in
gear longer, or to downshift for more
power or engine braking.
The transmission will only allow
shifting into gears appropriate for the
vehicle speed and engine revolutions
per minute (rpm). If shifting is
prevented for any reason, a SHIFT
DENIED message will be displayed in
the instrument cluster. The
transmission will not automatically
shift to the next higher gear if the
engine rpm is too high. It will only automatically shift to the next lower
gear if the engine rpm is much
too low.

188 DRIVING AND OPERATING
Drive Systems
All-Wheel Drive
Vehicles with this feature can operate
in All-Wheel Drive (AWD) Mode.
When the AWD feature is active, the
system transfers engine power,
if required, to all four wheels. The
system is fully automatic and adjusts
to road conditions for improved
traction and control. In FWD Mode
engine power is transferred to the
front wheels only, and the AWD
feature is off.
The AWD feature is automatically
activated when certain modes are
selected using the Driver Mode
Control switch. When an AWD mode
change is requested the light will flash
briefly while the system is engaging
and the AWD light will be displayed
when the system is active. When a
non-AWD Mode is selected, the light
will flash briefly while the system
disengages and a 2WD light will be
displayed when the AWD system is
off. SeeDriver Mode Control 0193. When a compact spare tire is installed
on an AWD vehicle, the system will
automatically detect the compact
spare and reduce AWD performance
to protect the system. To restore AWD
operation and prevent excessive wear
on the system, replace the compact
spare with a full-size tire as soon as
possible. See
Compact Spare Tire 0305.
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 vehicle
shutdown. 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 XT4 Owner Manual (GMNA-Localizing-U.S./Canada/Mexico-
13527548) - 2020 - CRC - 9/5/19
DRIVING AND OPERATING 189
If there is a problem with ABS, this
warning light stays on. SeeAntilock
Brake System (ABS) Warning Light
0 118.
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 vehicle has an Electric Parking
Brake (EPB). The EPB can always be
activated, even if the ignition is off. To
prevent draining the battery, avoid
repeated cycles of the EPB system
when the engine is not running. The system has a
Yor PARK
Electric Parking Brake light, and a
8
Service Parking Brake light. See
Electric Parking Brake Light 0117 and
Service Electric Parking Brake Light
0 118.
Before leaving the vehicle, check for
the
Yor PARK 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
Yor PARK light will flash and
then stay on once the EPB is fully
applied. If the
Yor PARK 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

StabiliTrak/ESC selectively applies
braking pressure at any one of the
vehicle's brakes to help steer the
vehicle in the direction which you are
steering.
If cruise control is being used and
traction control or StabiliTrak/ESC
begins to limit wheel spin, cruise
control will disengage. Cruise control
may be turned back on when road
conditions allow. TCS and StabiliTrak/
ESC will automatically turn on when
cruise control is set.
Both systems come on automatically
when the vehicle is started and begins
to move. The systems may be heard or
felt while they are operating or while
performing diagnostic checks. This is
normal and does not mean there is a
problem with the vehicle.
It is recommended to leave both
systems on for normal driving
conditions, but it may be necessary to
turn TCS off if the vehicle gets stuck
in sand, mud, ice, or snow. SeeIf the
Vehicle Is Stuck 0167 and “Turning
the Systems Off and On ”later in this
section.
The indicator light for both systems is
in the instrument cluster. This
light will:
. Flash when TCS is limiting
wheel spin.
. Flash when StabiliTrak/ESC is
activated.
. Turn on and stay on when either
system is not working.
If either system fails to turn on or to
activate, a message may display in the
Driver Information Center (DIC), and
dcomes on and stays on to indicate
that the system is inactive and is not
assisting the driver in maintaining
control. The vehicle is safe to drive,
but driving should be adjusted
accordingly.
If
dcomes on and stays on:
1. Stop the vehicle. 2. Turn the engine off and wait
15 seconds.
3. Start the engine.
Drive the vehicle. If
dcomes on and
stays on, the vehicle may need more
time to diagnose the problem. If the
condition persists, see your dealer.

The Performance Algorithm Liftfoot
(PAL) feature is enabled in Sport
Mode. PAL allows the transmission to
hold the current gear after a quick
release of a heavily applied accelerator
pedal. This provides greater engine
braking and enhanced vehicle control.
When PAL is activated, there may be
an additional green gear symbol which
appears in the instrument cluster
display. SeeGear Shifting Light 0118.
AWD : AWD Mode provides drive
torque to all four wheels. Select AWD
to improve traction and control on
slippery road surfaces, such as gravel,
sand, wet pavement, snow, and ice.
AWD is active in Sport and Off Road
Modes. AWD Mode is only available
on vehicles equipped with AWD.

this mode for off-road recreational
driving. When active, Off Road Mode
modifies accelerator pedal response,
AWD torque, and TCS. Choosing Off
Road Mode also engages AWD.Cruise Control
{Warning
Cruise control can be dangerous
where you cannot drive safely at a
steady speed. Do not use cruise
control on winding roads or in
heavy traffic.
Cruise control can be dangerous on
slippery roads. On such roads, fast
changes in tire traction can cause
excessive wheel slip, and you could
lose control. Do not use cruise
control on slippery roads.
With cruise control, a speed of about
40 km/h (25 mph) or more can be
maintained without keeping your foot
on the accelerator. Cruise control does
not work at speeds below about
40 km/h (25 mph).
