.Your vehicle's windshield is dirty,
cracked, or obstructed by
something that blocks the view of
the light sensor.
. Your vehicle is loaded such that
the front end points upward,
causing the light sensor to aim
high and not detect headlamps
and taillamps.
. Driving on winding or hilly roads.
The automatic high-beam headlamps
may need to be disabled if any of the
above conditions exist.
Exterior Lamps Off
Reminder
A warning chime will sound if the
exterior lamp control is left on in
either the headlamp or parking lamp
position and the driver door is opened
with the ignition off.
Headlamp High/Low-Beam
Changer
Push the turn signal lever away from
you and release, to turn the high
beams on. To return to low beams,
push the lever again or pull it toward
you and release.
This indicator light turns on in the
instrument cluster when the
high-beam headlamps are on.
Flash-to-Pass
This feature allows the high-beam
headlamps to be used to signal the
driver in front of you that you want
to pass.
Pull and hold the turn signal lever
toward you to use this feature. When
this is done the following will occur: .
If the headlamps are off or in
low-beam mode, the high-beam
headlamps will turn on. They will
stay on as long as the lever is held
there. Release the lever to turn
them off.
. If the headlamps are in high-beam
mode, they will go to low beam.
Daytime Running
Lamps (DRL)
DRL can make it easier for others to
see the front of your vehicle during
the day. Fully functional DRL are
required on all vehicles first sold in
Canada.
The dedicated DRL will come on when
all of the following conditions are met:
.The ignition is on.
. The exterior lamp control is
in AUTO.
. The light sensor determines it is
daytime.
. The vehicle is not parked.
The taillamps, instrument panel
lights, and other lamps will not be on.

LIGHTING 161
The battery can be discharged at idle
if the electrical loads are very high.
This is true for all vehicles. This is
because the generator (alternator)
may not be spinning fast enough at
idle to produce all the power that is
needed for very high electrical loads.
A high electrical load occurs when
several of the following are on, such
as: headlamps, high beams, fog lamps,
rear window defogger, climate control
fan at high speed, heated seats, engine
cooling fans, and loads plugged into
accessory power outlets.
EPM works to prevent excessive
discharge of the battery. It does this
by balancing the generator's output
and the vehicle's electrical needs.
It can increase engine idle speed to
generate more power, whenever
needed. It can temporarily reduce the
power demands of some accessories.
Normally, these actions occur in steps
or levels, without being noticeable. In
rare cases at the highest levels of
corrective action, this action may be
noticeable to the driver. If so, a DIC
message might be displayed. If a
battery message is displayed, it isrecommended that the driver reduce
the electrical loads as much as
possible. See
Driver Information Center
(DIC) 0138.
Battery Power Protection
The battery saver feature is designed
to protect the vehicle's battery.
If some interior lamps are left on and
the ignition is turned off, the battery
rundown protection system
automatically turns the lamp off after
some time.
Exterior Lighting Battery
Saver
The exterior lamps turn off about
10 minutes after the ignition is turned
off, if the parking lamps or headlamps
have been manually left on. This
protects against draining the battery.
To restart the 10-minute timer, turn
the exterior lamp control to the
O
position and then back to the;or
2position. To keep the lamps on for more than
10 minutes, the ignition must be on or
in ACC/ACCESSORY.

DRIVING AND OPERATING 179
Refer to the infotainment section for
more information on using that
system and the navigation system,
if equipped, including pairing and
using a cell phone.
Defensive Driving
Defensive driving means“always
expect the unexpected.” The first step
in driving defensively is to wear the
seat belt. See Seat Belts068.
. Assume that other road users
(pedestrians, bicyclists, and other
drivers) are going to be careless
and make mistakes. Anticipate
what they might do and be ready.
. Allow enough following distance
between you and the driver in
front of you.
. Focus on the task of driving.
Drunk Driving
Death and injury associated with
drinking and driving is a global
tragedy.
{Warning
Drinking and then driving is very
dangerous. Your reflexes,
perceptions, attentiveness, and
judgment can be affected by even a
small amount of alcohol. You can
have a serious —or even fatal —
collision if you drive after drinking.
Do not drink and drive or ride with
a driver who has been drinking.
Ride home in a cab; or if you are
with a group, designate a driver
who will not drink.
Control of a Vehicle
Braking, steering, and accelerating are
important factors in helping to control
a vehicle while driving.
Braking
Braking action involves perception
time and reaction time. Deciding to
push the brake pedal is perception
time. Actually doing it is
reaction time. Average driver reaction time is about
three-quarters of a second. In that
time, a vehicle moving at 100 km/h
(60 mph) travels 20 m (66 ft), which
could be a lot of distance in an
emergency.
Helpful braking tips to keep in mind
include:
.
Keep enough distance between
you and the vehicle in front
of you.
. Avoid needless heavy braking.
. Keep pace with traffic.
If the engine ever stops while the
vehicle is being driven, brake normally
but do not pump the brakes. Doing so
could make the pedal harder to push
down. If the engine stops, there will
be some power brake assist but it will
be used when the brake is applied.
Once the power assist is used up, it
can take longer to stop and the brake
pedal will be harder to push.

Cadillac CTS/CTS-V Owner Manual (GMNA-Localizing-U.S./Canada/Mexico-
12460273) - 2019 - CRC - 5/16/18
DRIVING AND OPERATING 183
For the LT4 6.2L supercharged engine,
consider using 100 octane unleaded
gasoline if the air temperature is
above 30 °C (86 °F). Do not use any
fuel with conditions listed in
Prohibited Fuels0245.
Automatic Transmission Fluid
Have the transmission fluid set to the
track specific oil level prior to track
usage. Transmission fluid should be
changed after every 15 hours of track
usage. Any transmission level set or
change should be performed at your
dealer.
Brake Fluid
For track events and competitive
driving, it is recommended that the
brake fluid be replaced with a high
performance brake fluid that has a dry
boiling point greater than 279 °C
(534 °F). After conversion to the high
performance brake fluid, follow the
brake fluid service recommendations
outlined by the fluid manufacturer. Do
not use silicone or DOT-5 brake fluids.
Caution
Removing the splash shield can
degrade wet braking performance,
as well as introduce brake pedal
pulsation, due to brake disc
exposure to road debris. Only
remove the front brake disc splash
shield and front tire deflector when
driving in track events.
Brake cooling can be improved if the
front brake disc splash shield and
front tire deflector are removed.
Removing the shield will require that
the suspension bushings visible to the
brake disc be protected with insulated
thermal wrapping.
Brake Burnishing
To prepare the V-Sport and V-Series
brake systems for track events and
racing, complete the appropriate high
performance brake burnishing
procedure described below. V-Sport and V-Series Brake
Burnishing
New brake pads must be burnished
before racing or other competitive
driving.
Caution
These procedures are specific to the
V-Sport and V-Series brake package.
This procedure should not be run
on other models as damage may
result.
Caution
The new vehicle break-in period
should be completed before
performing the brake burnishing
procedure or damage may occur to
the powertrain/engine. See
New
Vehicle Break-In 0192.
When performed as instructed, this
procedure will not damage the brakes.
During the burnishing procedure, the
brake pads will smoke and produce an
