.The light sensor determines it is
daytime.
. The parking brake is released or
the vehicle is not in P (Park).
The taillamps, sidemarker lamps,
instrument panel lights, and other
lamps will not be on.
The DRL turn off when the headlamps
are turned to
Oor the ignition is off.
For vehicles first sold in Canada, the
DRL can only be turned off when the
transmission is in P (Park).
Automatic Headlamp
System
When the exterior lamp control is set
to AUTO and it is dark enough
outside, the headlamps come on
automatically.
There is a light sensor on top of the
instrument panel. Do not cover the
sensor, otherwise the headlamps will
come on when they are not needed.
The system may also turn on the
headlamps when driving through a
parking garage or tunnel.
If the vehicle is started in a dark
garage, the automatic headlamp
system comes on immediately. If it is
light outside when the vehicle leaves
the garage, there is a slight delay
before the automatic headlamp
system changes to the DRL. During
that delay, the instrument cluster may
not be as bright as usual. Make sure
the instrument panel brightness control is in the full bright position.
See
Instrument Panel Illumination
Control 0149.
When it is bright enough outside, the
headlamps will turn off or may change
to Daytime Running Lamps (DRL).
The automatic headlamp system turns
off when the exterior lamp control is
turned to

Lights On with Wipers
If the windshield wipers are activated
in daylight with the engine on, and
the exterior lamp control is in AUTO,
the headlamps, parking lamps, and
other exterior lamps come on. The
transition time for the lamps coming
on varies based on wiper speed. When
the wipers are not operating, these
lamps turn off. Move the exterior
lamp control to

DRIVING AND OPERATING 171
Refer to the infotainment manual 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 Belts064.
. 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.

12460272) - 2019 - crc - 5/8/18
172 DRIVING AND OPERATING
Steering
Variable Effort Steering
The vehicle has a steering system that
varies the amount of effort required to
steer the vehicle in relation to the
speed of the vehicle.
The amount of steering effort required
is less at slower speeds to make the
vehicle more maneuverable and easier
to park. At faster speeds, the steering
effort increases to provide a sport-like
feel to the steering. This provides
maximum control and stability.
Electric Power Steering
The vehicle has electric power
steering. It does not have power
steering fluid. Regular maintenance is
not required.
If power steering assist is lost due to a
system malfunction, the vehicle can
be steered, but may require increased
effort. See your dealer if there is a
problem.If the steering wheel is turned until it
reaches the end of its travel and is
held against that position for an
extended period of time, power
steering assist may be reduced.
If the steering assist is used for an
extended period of time while the
vehicle is not moving, power assist
may be reduced.
Normal use of the power steering
assist should return when the system
cools down.
See your dealer if there is a problem.
Curve Tips
.
Take curves at a reasonable speed.
. Reduce speed before entering a
curve.
. Maintain a reasonable steady
speed through the curve.
. Wait until the vehicle is out of the
curve before accelerating gently
into the straightaway.
Steering in Emergencies
.There are some situations when
steering around a problem may be
more effective than braking.
. Holding both sides of the steering
wheel allows you to turn
180 degrees without removing
a hand.
. Antilock Brake System (ABS)
allows steering while braking.
Off-Road Recovery
The vehicle's right wheels can drop off
the edge of a road onto the shoulder
while driving. Follow these tips:

Cadillac ATS/ATS-V Owner Manual (GMNA-Localizing-U.S./Canada/Mexico-
12460272) - 2019 - crc - 5/8/18
DRIVING AND OPERATING 173
1. Ease off the accelerator and then,if there is nothing in the way,
steer the vehicle so that it
straddles the edge of the
pavement.
2. Turn the steering wheel about one-eighth of a turn, until the
right front tire contacts the
pavement edge.
3. Turn the steering wheel to go straight down the roadway.
Loss of Control
Skidding
There are three types of skids that
correspond to the vehicle's three
control systems:
.Braking Skid —wheels are not
rolling.
. Steering or Cornering Skid —too
much speed or steering in a curve
causes tires to slip and lose
cornering force.
. Acceleration Skid —too much
throttle causes the driving wheels
to spin. Defensive drivers avoid most skids by
taking reasonable care suited to
existing conditions, and by not
overdriving those conditions. But
skids are always possible.
If the vehicle starts to slide, follow
these suggestions:
.
Ease your foot off the accelerator
pedal and steer the way you want
the vehicle to go. The vehicle may
straighten out. Be ready for a
second skid if it occurs.
. Slow down and adjust your driving
according to weather conditions.
Stopping distance can be longer
and vehicle control can be affected
when traction is reduced by water,
snow, ice, gravel, or other material
on the road. Learn to recognize
warning clues —such as enough
water, ice, or packed snow on the
road to make a mirrored surface
— and slow down when you have
any doubt.
. Try to avoid sudden steering,
acceleration, or braking, including
reducing vehicle speed by shifting to a lower gear. Any sudden
changes could cause the tires to
slide.
Remember: Antilock brakes help avoid
only the braking skid.
Track Events and
Competitive Driving
{Danger
High-performance features are
intended for use only on closed
tracks by experienced and qualified
drivers and should not be used on
public roads. High-speed driving,
aggressive cornering, hard braking,
and other high-performance driving
can be dangerous. Improper driver
inputs for the conditions may result
in loss of control of the vehicle,
which could injure or kill you or
others. Always drive safely.
Competitive driving may affect the
vehicle warranty. See the warranty
manual before using the vehicle for
competitive driving.

174 DRIVING AND OPERATING
Caution
Low oil levels can damage the
engine. If using the vehicle for
competitive driving, the engine may
use more oil than it would with
normal use. Check the oil level
often during competitive driving.
Competitive Driving Mode can be
selected. See Driver Mode Control
0 205.

Fuel
Use premium unleaded gasoline with
a posted octane rating of 93 at a track
event. Unleaded gasoline with a
posted octane rating of 91 may be
used, but performance will be
degraded.
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.
Manual Transmission Fluid
Manual transmission fluid should be
changed after every 15 hours of track
usage.
Brake Fluid
.Before racing, replace existing
brake fluid with a qualified racing
brake fluid from a sealed
container. Brake fluid with a dry
boiling point >279 °C (534 °F) is
qualified. If racing brake fluid is
used, replace it with GM approved
brake fluid before driving on
public roads. See Recommended
Fluids and Lubricants 0337.
. Do not use silicone-based fluids.
If racing brake fluid is in the vehicle
and the age of the brake fluid is over a
month old or unknown, replace the
brake fluid between racing/closed
track driving.
