238 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.
Track Events and
Competitive Driving
(V-Series and
V-Series Blackwing)
Before any track event, there
are three features that should
be turned off:
.Automatic Emergency
Braking (AEB). See

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.

Park Assist
The vehicle may be equipped
with the Rear Park Assist
(RPA) or Front and Rear Park
Assist (FRPA). The Park Assist
system may provide
assistance to driver when
backing up and parking. Park
Assist uses ultrasonic sensors
in the bumpers to measure the
distance between the vehicle
and objects. The system
calculates the distance
between vehicle and object via
measuring the time it takes for
the ultrasonic waves to
bounce back from the object. Park Assist works only at
speeds up to about 11 Km/h
(7 mph). An illuminated LED in
the parking assist button
indicates that the system is
ready to operate. The sensors
on the bumpers may detect
objects up to 1.8m (6 ft) behind
and 1.25m (4 ft) in front of the
vehicle within a zone 25 cm
(10 in) high off the ground and
below bumper level. These
detection distances may be
shorter during warmer or
humid weather. Blocked
sensors will not detect objects
and can also cause false
detections. Keep the sensors
clean of mud, dirt, snow, ice,
and slush; and clean sensors
after a car wash in freezing
temperatures.
{Warning
The Park Assist System is
no substitute for careful and
attentive driving. The Park
Assist system does not
