210 DRIVING AND OPERATING
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.Driving on Wet Roads
Rain and wet roads can reduce vehicle
traction and affect your ability to stop
and accelerate. Always drive slower in
these types of driving conditions and
avoid driving through large puddles
and deep-standing or flowing water.
{Warning
Wet brakes can cause crashes. They
might not work as well in a quick
stop and could cause pulling to one
side. You could lose control of the
vehicle.
After driving through a large puddle
of water or a car/vehicle wash,
lightly apply the brake pedal until
the brakes work normally.
Flowing or rushing water creates
strong forces. Driving through
flowing water could cause the
vehicle to be carried away. If this
happens, you and other vehicle
occupants could drown. Do not (Continued)
Warning (Continued)
ignore police warnings and be very
cautious about trying to drive
through flowing water.
Hydroplaning
Hydroplaning is dangerous. Water can
build up under the vehicle's tires so
they actually ride on the water. This
can happen if the road is wet enough
and you are going fast enough. When
the vehicle is hydroplaning, it has
little or no contact with the road.
There is no hard and fast rule about
hydroplaning. The best advice is to
slow down when the road is wet.
Other Rainy Weather Tips
Besides slowing down, other wet
weather driving tips include:
.Allow extra following distance.
. Pass with caution.
. Keep windshield wiping equipment
in good shape.
. Keep the windshield washer fluid
reservoir filled.

Cadillac CT6 Owner Manual (GMNA-Localizing-U.S./Canada-11292458) -
2018 - crc - 2/14/17
212 DRIVING AND OPERATING
.Allow greater following distance
and watch for slippery spots. Icy
patches can occur on otherwise
clear roads in shaded areas. The
surface of a curve or an overpass
can remain icy when the
surrounding roads are clear. Avoid
sudden steering maneuvers and
braking while on ice.
. Turn off cruise control.
Blizzard Conditions
Stop the vehicle in a safe place and
signal for help. Stay with the vehicle
unless there is help nearby. If possible,
use Roadside Service. See Roadside
Service 0411. To get help and keep
everyone in the vehicle safe:
. Turn on the hazard warning
flashers.
. Tie a red cloth to an outside
mirror.
{Warning
Snow can trap engine exhaust
under the vehicle. This may cause
exhaust gases to get inside. Engine
exhaust contains carbon monoxide
(CO), which cannot be seen or
smelled. It can cause
unconsciousness and even death.
If the vehicle is stuck in snow:
. Clear snow from the base of
the vehicle, especially any
blocking the exhaust pipe.
. Open a window about 5 cm
(2 in) on the vehicle side that
is away from the wind, to
bring in fresh air.
. Fully open the air outlets on
or under the instrument
panel.
. Adjust the climate control
system to circulate the air
inside the vehicle and set the
fan speed to the highest
setting. See “Climate Control
Systems.”
(Continued)
Warning (Continued)
For more information about CO, see
Engine Exhaust0230.
To save fuel, run the engine for short
periods to warm the vehicle and then
shut the engine off and partially close
the window. Moving about to keep
warm also helps.
If it takes time for help to arrive,
when running the engine, push the
accelerator pedal slightly so the
engine runs faster than the idle speed.
This keeps the battery charged to
restart the vehicle and to signal for
help with the headlamps. Do this as
little as possible, to save fuel.
If the Vehicle Is Stuck
Slowly and cautiously spin the wheels
to free the vehicle when stuck in sand,
mud, ice, or snow.
If stuck too severely for the traction
system to free the vehicle, turn the
traction system off and use the
rocking method. See Traction Control/
Electronic Stability Control 0239.

weight of the driver, passengers,
and cargo should never exceed the
vehicle's capacity weight.
Certification Label
Label Example
A vehicle-specific Certification
label is attached to the vehicle's
center pillar (B-pillar). The label
may show the gross weight
capacity of the vehicle, called the
Gross Vehicle Weight Rating
(GVWR). The GVWR includes the
weight of the vehicle, all
occupants, fuel, and cargo.
{Warning
Things inside the vehicle can
strike and injure people in a
sudden stop or turn, or in a
crash.
.Put things in the cargo
area of the vehicle. In the
cargo area, put them as far
forward as possible. Try to
spread the weight evenly.
.Never stack heavier things,
like suitcases, inside the
vehicle so that some of
them are above the tops of
the seats.
.Do not leave an unsecured
child restraint in the
vehicle.
.Secure loose items in the
vehicle.
.Do not leave a seat folded
down unless needed.
Starting and Operating
New Vehicle Break-In
(Gasoline Engine Only)
Follow these recommended guidelines
during the first 2 400 km (1,500 mi) of
driving this vehicle. Parts have a
break-in period and performance will
be better in the long run.
For the first 2 400 km (1,500 mi):
. Avoid full throttle starts and
abrupt stops.
. Do not exceed 4000 engine rpm.
. Avoid driving at any one constant
speed, fast or slow.
. Avoid downshifting to brake or
slow the vehicle when the engine
speed will exceed 4000 rpm.
. Do not let the engine labor. Never
lug the engine in high gear at low
speeds.
. Do not participate in track events,
sport driving schools, or similar
activities during this break-in
period.

Cadillac CT6 Owner Manual (GMNA-Localizing-U.S./Canada-11292458) -
2018 - crc - 2/14/17
DRIVING AND OPERATING 217
.Check engine oil with every
refueling and add if necessary. Oil
and fuel consumption may be
higher than normal during the
first 2 400 km (1,500 mi).
. To break in new tires, drive at
moderate speeds and avoid hard
cornering for the first
300 km (200 mi). New tires do not
have maximum traction and may
tend to slip.
. New brake linings also need a
break–in period. Avoid making
hard stops during the first
300 km (200 mi). This is
recommended every time brake
linings are replaced.Ignition Positions
The vehicle has an electronic keyless
ignition with pushbutton start.
The Remote Keyless Entry (RKE)
transmitter must be in the vehicle for
the system to operate. If the
pushbutton start is not working, the
vehicle may be near a strong radio
antenna signal causing interference to
the Keyless Access system. See Remote
