DRIVING AND OPERATING 199
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 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.
ABS performs a system check when
the vehicle is first driven.
A momentary motor or clicking noisemay be heard while this test is going
on, and the brake pedal may move
slightly. This is normal.
If there is a problem with ABS, this
warning light stays on. See
Antilock
Brake System (ABS) Warning Light
0 126.
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.

Cadillac CT6 Owner Manual (GMNA-Localizing-U.S./Canada-13566829) -
2020 - CRC - 6/14/19
DRIVING AND OPERATING 205
The Driver Mode Control has multiple
modes: Tour, Sport, Snow/Ice, and
Track. The Track Mode is available for
V-Series models only. All modes have
preset vehicle settings for use in
different driving conditions. For
further detail see“Mode Description ”.
To activate a mode, press
yorzon
the MODE switch to make a mode
selection in the instrument cluster.
Every press will scroll to the next
available mode.
Mode Description
The following describes the modes
that can be selected in further detail.
Tour Mode
Use for normal city and highway
driving to provide a smooth, soft ride.
This setting provides a balanced
setting between comfort and handling.
This is the standard mode. For further
details on Tour Mode, see “Driver
Mode Selector Attributes Affected ”.
Sport Mode
Use where road conditions or personal
preference demand a more controlled
response.
When selected, the Sport Mode
indicator light will display in the
instrument cluster.
In this mode, the vehicle monitors
driving behaviors and automatically
enables Performance Shift Features
when spirited driving is detected.
These features maintain lower
transmission gears to increase
available engine braking and improve
acceleration response. The vehicle will exit these features and return to
normal operation after a short period
when no spirited driving is detected.
The steering including Active Rear
Steer (if equipped), will change to
provide more precise control. If the
vehicle has Magnetic Ride Control, the
suspension will change to provide
better cornering performance. If the
vehicle is equipped with AWD, Sport
Mode sends more torque to the rear
wheels.
For further details on Sport Mode, see
“Driver Mode Selector Attributes
Affected”.
Snow/Ice Mode
Snow/Ice Mode is used for slippery
surfaces to help control wheel speed.
This can compromise the acceleration
on dry asphalt. Snow/Ice Mode will
use a different accelerator pedal map
to optimize traction on a slippery
surface. The accelerator pedal will
reduce engine torque at small pedal
inputs.

208 DRIVING AND OPERATING
Engine Sound
Adjusts the volume of engine noise
from quietest in Tour mode to most
robust in Track mode.
Steering
Adjusts from a lighter steering feel in
Tour Mode to reduced assist in Sport
and Track Mode for more
steering feel.
Suspension (if equipped with
Magnetic Ride)
Adjusts the shock dampening
firmness from a comfort tune in Tour
Mode to an optimized responsiveness
tune in Sport and Track.
Traction and Stability Control
StabiliTrak/Electronic Stability Control
(ESC) can be turned off by pressing
and holding the button for
five seconds.
Driver Mode Customization
The Engine Sound Management,
steering, and suspension drive modes
can be set to the driver’s preference.
See“Driving Mode ”under Vehicle
Personalization 0140. When in the Track main vehicle mode,
you cannot overwrite the Steering or
Suspension settings. These settings
are designed to interact with the
advanced functions in the Track Mode
and cannot be overwritten.
The selections made in the Driving
Mode menu overwrite the main
vehicle mode selection via the buttons
or switch on the center console. In
order to customize and overwrite,
select one of the three settings by
touching the infotainment display.
When in the customization screen for
each system, select one of the
available options:
•
Auto (Follows the MODE switch)
• Tour
• Sport
• Track (V-Series only) The default will be to follow the
vehicle MODE switch settings, but the
main vehicle mode selection for the
currently selected system can be
overwritten using this menu. The
settings selected in this menu will set
the vehicle behavior in all selected
vehicle modes, and will be retained
over each ignition cycle. They do not
have to be reset each time the vehicle
is started.
Locking Rear Axle
Vehicles with a limited-slip rear axle
can give more traction on snow, mud,
ice, sand, or gravel. When traction is
low, this feature allows the drive
wheel with the most traction to move
the vehicle. The limited-slip rear axle
also gives the driver enhanced control
when cornering hard or completing a
maneuver, such as a lane change. For
vehicles with limited-slip rear axle, the
rear axle fluid should be changed. See
Maintenance Schedule
0359.
