Driver Mode Control
Driver Mode Control attempts to add
a sportier feel, provide a more
comfortable ride, or assist in different
weather conditions or terrain. This
system simultaneously changes the
software settings of various
sub-systems. Depending on the option
package, available features, and mode
selected, the suspension, steering, and
powertrain will change settings to
achieve the desired mode
characteristics. If the vehicle is
equipped with Magnetic Ride Control,
selecting the various Driver Modes
adjusts the ride of the vehicle to
enhance the ride performance for the
road conditions and the
selected mode. While in the Sport and/or Track
Modes, the vehicle monitors driving
behavior 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 Sport or
Track Mode operation after a short
period when no spirited driving is
detected.

Launch Control (V-Series Only)
A Launch Control feature is available,
within Competitive Driving Mode or
Performance Traction Management
(V-Series), to allow the driver to
achieve high levels of vehicle
acceleration in a straight line. Launch
Control is a form of traction control that manages tire spin while
launching the vehicle. This feature is
intended for use during closed course
race events where consistent zero to
60 and quarter mile times are
desirable.
Launch Control is only available when
the following criteria are met:
.
Competitive Driving Mode is
selected or any of the Performance
Traction Management modes are
selected (V-Series). The TCS light
comes on the instrument panel
and the appropriate DIC message
displays.
. The vehicle is not moving.
. The steering wheel is pointing
straight.
. The brake pedal must be firmly
pressed to the floor, equivalent to
a panic brake event.
. The accelerator pedal is rapidly
applied to wide open throttle. (If
the vehicle rolls due to wide open
throttle, release the throttle, press
the brake pedal more firmly, and
re-apply the accelerator to wide
open throttle.)

Cadillac CTS/CTS-V Owner Manual (GMNA-Localizing-MidEast-10293089) -
2017 - crc - 6/22/16
DRIVING AND OPERATING 217
The Launch Control feature will
initially limit engine speed as the
driver rapidly applies the accelerator
pedal to wide open throttle. Allow the
engine rpm to stabilize. A smooth,
quick release of the brake pedal, while
maintaining the fully pressed
accelerator pedal, will manage
wheel slip.
After the vehicle is launched, the
system continues in Competitive
Driving Mode or Performance Traction
Management (V-Series).
Competitive Driving Mode, PTM, and
Launch Control are systems designed
for a closed course race track and not
intended for use on public roads. The
systems are not intended to
compensate for lack of driver
experience or familiarity with the race
track.Limited-Slip Differential
(Except V-Series)
If equipped, the mechanical
limited-slip differential can give more
traction on snow, mud, ice, sand,
or gravel. It works like a standard axle
most of the time, but when traction is
low, this feature allows the drive
wheel with the most traction to move
the vehicle. For vehicles with
limited-slip differential, driven under
severe conditions, the rear axle fluid
should be changed. SeeCompetitive
Driving Mode 0214 and Maintenance
Schedule 0324.
Limited-Slip Differential
(V-Series Only)
If equipped, the Electronic
Limited-Slip Differential (eLSD) is
automatically activated. eLSD actively
monitors vehicle sensors and driver
inputs to determine the amount of
change for the conditions. With eLSD,
the vehicle has:
.
Enhanced high-speed control. .
Improved traction through
corners, allowing more
acceleration.
. More precise steering.
. Increased vehicle agility.
. Integration with StabiliTrak.
For vehicles with eLSD, driven under
severe conditions, the rear axle fluid
should be changed. See Competitive
Driving Mode 0214 and Maintenance
Schedule 0324.

242 DRIVING AND OPERATING
How the System Works
The LKA camera sensor is on the
windshield ahead of the rearview
mirror.
To turn LKA on and off, press
A
on the center stack.
When on,
Ais green if LKA is
available to assist and provide LDW
alerts. It may assist by gently turning
the steering wheel and display
A
as amber if the vehicle approaches a
detected lane marking without using a
turn signal in that direction. It may
also provide an LDW alert by
flashing
Aamber as the lane
marking is crossed. Additionally, there
will be three beeps, or the driver seat
will pulse three times, on the right or
left, depending on the lane departure
direction.
The LKA system does not
continuously steer the vehicle. If LKA
does not detect active driver steering,
an alert and chime may be provided.
Move the steering wheel to dismiss.
When the System Does Not
Seem to Work Properly
The system performance may be
affected by:
. Close vehicles ahead.
. Sudden lighting changes, such as
when driving through tunnels.
. Banked roads.
. Roads with poor lane markings,
such as two-lane roads.
If the LKA system is not functioning
properly when lane markings are
clearly visible, cleaning the windshield
may help.
LKA assistance and/or LDW alerts
may occur due to tar marks, shadows,
cracks in the road, temporary or
construction lane markings, or other
road imperfections. This is normal
system operation; the vehicle does not
need service. Turn LKA off if these
conditions continue.
Fuel
Use the recommended fuel for proper
vehicle maintenance.
For the LTG 2.0L L4 turbo engine, use
unleaded petrol with a posted octane
rating of 95 RON or higher. Unleaded
petrol rated at 91 RON can be used,
but acceleration and fuel economy
will be reduced, and an audible
knocking noise may be heard. If this
occurs, use petrol rated at 95 RON as
soon as possible, otherwise the engine
could be damaged. If heavy knocking
is heard when using unleaded petrol
rated at 95 RON, the engine needs
service.
For the LGX 3.6L V6 engine, use
unleaded petrol with a posted octane
rating of 91 RON or higher, otherwise
an audible knocking noise may be
heard. If heavy knocking is heard
when using gasoline rated at 91 RON
or higher, the engine needs service.
For the LF3 3.6L V6 Twin Turbo and
LT4 6.2L V8 engines, use unleaded
petrol with a posted octane rating of
95 RON or higher. If the octane is less
than 95 RON, the engine could be

DRIVING AND OPERATING 243
damaged and repairs would not be
covered by the vehicle warranty.
If heavy knocking is heard when using
petrol rated at 95 RON octane, the
engine needs service.
Caution
Do not use fuels with any of the
following conditions; doing so may
damage the vehicle and void its
warranty:. Fuel with any amount of
methanol, methylal, and
aniline. These fuels can
corrode metal fuel system
parts or damage plastic and
rubber parts.
. Fuel containing metals such
as methylcyclopentadienyl
manganese tricarbonyl
(MMT), which can damage
the emissions control system
and spark plugs.
. Fuel with a posted octane
rating of less than the
recommended fuel. Using this
(Continued)
Caution (Continued)
fuel will lower fuel economy
and performance, and may
decrease the life of the
emissions catalyst.
Fuel Additives
Gasoline should contain detergent
additives that help prevent engine and
fuel system deposits from forming.
Clean fuel injectors and intake valves
will allow the emission control system
to work properly. Some gasoline does
not contain sufficient quantities of
additives to keep fuel injectors and
intake valves clean. To make up for
this lack of detergency, consult your
dealer for the GM approved additive
treatment. Add this additive to the
fuel tank at every engine oil change or
every 15 000 km (9,000 mi), whichever
occurs first.
Filling the Tank
{Warning
Fuel vapors and fuel fires burn
violently and can cause injury or
death.
. To help avoid injuries to you
and others, read and follow
all the instructions on the
fuel pump island.
. Turn off the engine when
refueling.
. Keep sparks, flames, and
smoking materials away
from fuel.
. Do not leave the fuel pump
unattended.
. Do not use a cell phone while
refueling.
. Do not reenter the vehicle
