Park Assist
With RPA, as the vehicle backs up at speeds
of less than 8 km/h (5 mph), the sensors on
the rear bumper may detect objects up to
2.5 m (8 ft) behind 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 does not detect
children, pedestrians, bicyclists, animals,
or objects located below the bumper or
that are too close or too far from the
vehicle. It is not available at speeds
greater than 8 km/h (5 mph). To prevent
injury, death, or vehicle damage, even
with Park Assist, always check the area
around the vehicle and check all mirrors
before moving forward or backing.
The instrument cluster may have a Park
Assist display with bars that show“distance
to object” and object location information
for RPA. As the object gets closer, more bars
light up and the bars change color from
yellow to amber to red.
When an object is first detected in the rear,
one beep will be heard from the rear. When
an object is very close (<0.6 m (2 ft) in the
vehicle rear), five beeps will sound from
the rear.
Rear Cross Traffic Alert (RCTA)
System
If equipped, RCTA displays a red warning
triangle with a left or right pointing arrow
on the RVC screen to warn of traffic coming
from the left or right. This system detects
objects coming from up to 20 m (65 ft) from
the left or right side of the rear of the vehicle. When an object is detected, three
beeps sound from the left or right,
depending on the direction of the detected
vehicle.
RCTA can be turned on or off through
vehicle settings. To view available settings
from the infotainment screen, touch
Settings > Vehicle > Collision/Detection
Systems.
Side Blind Zone Alert (SBZA)
If equipped, the Side Blind Zone Alert (SBZA)
system is a lane-changing aid that assists
drivers with avoiding crashes that occur with
moving vehicles in the side blind zone,
or blind spot areas. The SBZA warning
display will light up in the corresponding
outside side mirror and will flash if the turn
signal in corresponding side is on.
{Warning
SBZA does not alert the driver to vehicles
rapidly approaching outside of the side
blind zones, pedestrians, bicyclists,
or animals. It may not provide alerts
when changing lanes under all driving
conditions. Failure to use proper care
when changing lanes may result in injury,

death, or vehicle damage. Before making
a lane change, always check mirrors,
glance over your shoulder, and use the
turn signals.
SBZA Detection Zones
The SBZA sensor covers a zone
approximately one lane over from both
sides of the vehicle, or approximately
3.5 m (11 ft). The height of the zone is
approximately between 0.5 m (1.5 ft) and
2 m (6 ft) off the ground. This zone starts at
approximately the middle of the vehicle and
goes back 5 m (16 ft).
How the System Works
The SBZA symbol lights up in the side
mirrors when the system detects a moving
vehicle in the next lane over that is in the
side blind zone. This indicates it may be
unsafe to change lanes. Before making a
lane change, check the SBZA display, check
mirrors, glance over your shoulder, and use
the turn signals.
Left Side Mirror DisplayRight Side Mirror Display
When the vehicle is started, both outside
mirror SBZA displays will briefly come on to
indicate the system is operating. When the
vehicle is in a forward gear, the left- or
right-side mirror display will light up if a
moving vehicle is detected in that blind
zone. If the turn signal is activated in the
same direction as a detected vehicle, this
display will flash as an extra warning not to
change lanes. SBZA can be disabled through vehicle
personalization. To view available settings
from the infotainment screen, touch
Settings > Vehicle > Collision/Detection
Systems. If SBZA is disabled by the driver,
the SBZA mirror displays will not light up.
When the System Does Not Seem to
Work Properly
SBZA displays may not come on when
passing a vehicle quickly, for a stopped
vehicle. SBZA may alert to objects attached
to the vehicle, such as a bicycle, or object
extending out to either side of the vehicle.
This is normal system operation; the vehicle
does not need service.
SBZA may not always alert the driver to
vehicles in the side blind zone, especially in
wet conditions. The system does not need
to be serviced. The system may light up due
to guardrails, signs, trees, shrubs, and other
non-moving objects. This is normal system
operation; the vehicle does not need service.
SBZA may not operate when the SBZA
sensors in the left or right corners of the
rear bumper are covered with mud, dirt,
snow, ice, or slush, or in heavy rainstorms.

Dual Clutch Transmission Fluid
How to Check Dual Clutch Transmission
Fluid
It is not necessary to check the transmission
fluid level. A transmission fluid leak is the
only reason for fluid loss. If a leak occurs,
take the vehicle to the dealer and have it
repaired as soon as possible. The vehicle is not equipped with a
transmission fluid level dipstick. There is a
special procedure for checking and changing
the transmission fluid. Because this
procedure is difficult, this should be done at
the dealer. Contact the dealer for additional
information or the procedure can be found
in the service manual. To purchase a service
manual, see
Publication Ordering
Information 0327.
Caution
Use of the incorrect transmission fluid
may damage the vehicle, and the
damage may not be covered by the
vehicle warranty. Always use the correct
transmission fluid. See Recommended
Fluids and Lubricants 0310.
Change the fluid and external canister filter
at the proper intervals. See Maintenance
Schedule 0306. Be sure to use the correct
fluid. See Recommended Fluids and
Lubricants 0310.
Dual Clutch Transmission Fluid Life
System
When to Change the Dual Clutch
Transmission Fluid
This vehicle has a computer that indicates
when to change the transmission fluid. This
is based on a combination of factors which
include temperature and miles driven. Based
on driving conditions, the mileage at which
a fluid change is indicated can vary
considerably. For the fluid life system to
work properly, the system must be reset
every time the fluid is changed. When the
system has calculated that fluid life has
been diminished, it indicates that a fluid
change is necessary. A CHANGE
TRANSMISSION FLUID SOON message comes
on. Change the fluid as soon as possible
within the next 1 000 km (600 mi). Failure
to change transmission fluid at required
intervals could lead to suboptimal
transmission performance. Your dealer has
trained service technicians who will change
the fluid and reset the system. If the system
is ever reset accidentally, the fluid must be
changed 72 000 km (45,000 mi) after the
last fluid change.

If coolant is needed, be sure the cooling
system is cool, then add the proper
DEX-COOL coolant mixture directly to the
surge tank.1. Open the Hatch/Trunk. See Hatch (Trunk)
0 19.
2. When the cooling system, including the
coolant surge tank pressure cap and
engine, is no longer hot, remove the
pressure cap.
Turn the pressure cap slowly
counterclockwise about one-quarter turn
and then stop.
If a hiss is heard, wait for that to stop.
A hiss means there is still some
pressure left.
3. Keep turning the pressure cap slowly, and remove it.4. Fill the coolant surge tank with theproper mixture until the level inside
stabilizes at the COLD FILL indicator in
the surge tank.
5. With the coolant surge tank pressure cap off, start the engine and let it run until
the engine is hot.
By this time, the coolant level inside the
coolant surge tank may be lower. If the
level is lower, add more of the proper
mixture to the coolant surge tank until
the level stabilizes at the COLD FILL
indicator in the coolant surge tank.
6. Replace the pressure cap tightly. 7. Verify coolant level after the engine is
shut off and the coolant is cold.
If necessary, repeat coolant fill procedure
Steps 3−7.
If the coolant still is not at the proper
level when the system cools down again,
see your dealer.
Caution
If the pressure cap is not tightly installed,
coolant loss and engine damage may
occur. Be sure the cap is properly and
tightly secured.
Engine Overheating
The vehicle has several indicators to warn of
engine overheating.
There is an engine coolant temperature
gauge on the instrument cluster. See Engine
Coolant Temperature Gauge 083. The
vehicle may also display a message on the
Driver Information Center (DIC).

Then check to see if the engine cooling fans
are running. There are two cooling fans
located in the front (one at each corner) and
two cooling fans in the rear (one on each
side of the engine). If the engine is
overheating, the fans should be running.
If they are not, do not continue to run the
engine, and have the vehicle serviced.
Caution
Do not run the engine if there is a leak
in the engine cooling system. This can
cause a loss of all coolant and can
damage the system and vehicle. Have
any leaks fixed right away.
If Steam Is Coming from the Engine
{Warning
Steam and scalding liquids from a hot
cooling system are under pressure.
Turning the pressure cap, even a little,
can cause them to come out at high
speed and you could be burned. Never
turn the cap when the cooling system,
including the pressure cap, is hot. Wait
for the cooling system and pressure cap
to cool.
If Steam Is Coming from the Engine
Compartment with no Overheat Warning
Water from rain and car washes could enter
the engine compartment and contact hot
surfaces. If steam is coming from the engine
compartment with no accompanying
overheat warning, no service is needed.
If No Steam Is Coming from the Engine
If an engine overheat warning is displayed
but no steam can be seen or heard, the
problem may not be too serious. Sometimes
the engine can get a little too hot when the
vehicle:
.Climbs a long hill on a hot day.
.Stops after high-speed driving.
.Idles for long periods in traffic.
If the overheat warning is displayed with no
sign of steam: 1. Turn the air conditioning off.
2. Turn the heater on to the highest temperature and to the highest fan
speed. Open the windows as necessary.
3. When it is safe to do so, pull off the road, shift to P (Park) or N (Neutral), and
let the engine idle. If the engine coolant temperature gauge is
no longer in the shaded area or an overheat
warning no longer displays, the vehicle can
be driven. Continue to drive the vehicle
slowly for about 10 minutes. Keep a safe
vehicle distance from the vehicle in front.
If the warning does not come back on,
continue to drive normally and have the
cooling system checked for proper fill and
function.
If the warning continues, pull over safely,
and park the vehicle right away.
If there is no sign of steam, idle the engine
for three minutes while parked. If the
warning is still displayed, turn off the
engine until it cools down.Washer Fluid
What to Use
When the vehicle needs windshield washer
fluid, be sure to read the manufacturer
instructions before use. If the vehicle will be
operating in an area where the temperature
may fall below freezing, use a fluid that has
sufficient protection against freezing.

Caution
Performing the brake burnish procedure
on a base brake system can result in
brake damage.
Perform this procedure only on dry
pavement, in a safe manner, and in
compliance with all local and state
ordinances/laws regarding motor vehicle
operation.
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 0189.
Caution
Brake fade can occur during this burnish
procedure and can cause brake pedal
travel and force to increase. This could
extend stopping distance until the brakes
are fully burnished.
Completing the following procedure as
instructed will not damage the brakes. The
brake pads may smoke and produce an odor. The braking force and pedal travel
may increase. After the procedure, the brake
pads may appear white at the rotor contact.
1. Using the Friction Bubble gauge, apply the brakes 10 times starting at 100 km/h
(60 mph) to 50 km/h (30 mph) while
decelerating at 0.4g. This is a medium
brake application. Drive for at lest 0.5 km
(0.3 mi) between applying the brakes.
2. If further cleanup of the brake discs is needed, repeat this procedure with 0.7g
applications.
As with all high performance brake systems,
some amount of brake squeal is normal.
Brake Pad Life System (If
Equipped)
When to Change Brake Pads
If equipped, this system estimates the
remaining life of the front and rear brake
pads. Brake Pad Life is displayed in the
Driver Information Center (DIC), along with
a percentage for each axle. The system must
be reset every time the brake pads are
changed. When the system has determined that the
brake pads need to be replaced, a message
displays, which may include mileage
remaining.
Brake pads should always be replaced as
complete axle sets.
How to Reset the Brake Pad Life System
The system will automatically detect when
significantly worn brake pads are replaced.
When the ignition is turned on after new
pads and wear sensors are installed, a
