When the System Does Not
Seem to Work Properly
The following messages may be
displayed on the DIC:
SERVICE PARKING ASSIST:If
this message occurs, check the
following conditions:
.The sensors are not clean. Keep
the vehicle's rear bumper free of
mud, dirt, snow, ice, and slush.
For cleaning instructions, see
Exterior Care on page 10-73.
.The park assist sensors are
covered by frost or ice. Frost or
ice can form around and behind
the sensors and may not always
be seen; this can occur after
washing the vehicle in cold
weather. The message may not
clear until the frost or ice has
melted.
If the above conditions do not exist,
take the vehicle to your dealer to
repair the system. PARK ASSIST OFF:
If the RPA
system does not activate due to a
temporary condition, the message
displays on the DIC. This can occur
under the following conditions:
.The driver has disabled the
system.
.A trailer was attached to the
vehicle, or an object was
hanging out of the liftgate during
the last drive cycle. Once the
object is removed, RPA will
return to normal operation.
.A tow bar is attached to the
vehicle.
.The bumper is damaged. Take
the vehicle to your dealer to
repair the system.
.Other conditions, such as
vibrations from a jackhammer or
the compression of air brakes on
a very large truck, are affecting
system performance.
Side Blind Zone
Alert (SBZA)
If equipped, the SBZA system is a
lane-changing aid that assists
drivers with avoiding crashes that
occur with vehicles in the side blind
zone (or spot) areas. The SBZA
warning display will light up in the
corresponding outside side mirror
and will flash if the turn signal 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

Warning (Continued)
check mirrors, glance over your
shoulder, and use the turn
signals.
SBZA Detection Zones
The SBZA sensor covers a zone of
approximately one lane over from
both sides of the vehicle, or 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 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 moving forward, the left or right side mirror display will light up
if a vehicle is detected in that blind
zone. If the turn signal is activated
in the same direction of a detected
vehicle, this display will flash as an
extra warning not to change lanes.
SBZA can be disabled through
vehicle personalization. See
“Collision Detection Systems”
under
Vehicle Personalization on
page 5-31. 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 or
when towing a trailer. The SBZA
detection zones that extend back
from the side of the vehicle do not
move further back when a trailer is
towed. Use caution while changing
lanes when towing a trailer. SBZA
may alert to objects attached to the
vehicle, such as a trailer, 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. For
cleaning instructions, see "Washing
the Vehicle" underExterior Care on
page 10-73. If the DIC still displays
the system unavailable message
after cleaning both sides of the
vehicle toward the rear corners of
the vehicle, see your dealer. If the SBZA displays do not light up
when vehicles are in the blind zone
and the system is clean, the system
may need service. Take the vehicle
to your dealer.
When SBZA is disabled for any
reason other than the driver turning
it off, the Side Blind Zone Alert On
option will not be available on the
personalization menu.
Radio Frequency Information

Radio Frequency Statement on
page 13-12.
Rear Vision
Camera (RVC)
If equipped, the RVC can assist the
driver when backing up by
displaying a view of the area behind
the vehicle.
{Warning
The RVC system does not display
children, pedestrians, bicyclists,
crossing traffic, animals, or any
other object located outside the
camera's field of view, below the
bumper, or under the vehicle.
Perceived distances may be
different from actual distances.
Do not back the vehicle using
only the RVC screen. Failure to
use proper care before backing
may result in injury, death,
or vehicle damage. Always check
behind and around the vehicle
before backing.
An image appears on the
infotainment screen when the
vehicle is shifted into R (Reverse).
The infotainment screen goes to the
previous screen after approximately
10 seconds once the vehicle is
shifted out of R (Reverse).

system must not be disabled to use
the caution symbols. The error
message Rear Parking Assist
Symbols Unavailable may display if
RPA has been disabled and the
symbols have been turned on. See
Parking Assist on page 9-39.
On vehicles with the Rear Cross
Traffic Alert (RCTA), a triangle with
an arrow may display on the RVC
screen to warn of traffic coming from
either direction. This system detects
objects coming from up to 20 m
(65 ft) from the left or right side,
behind the vehicle. When an object is detected, three beeps sound from
the left or right side, depending on
the direction of the detected vehicle.
The parking assist and RCTA
symbols appear and may cover an
object when viewing the
infotainment screen when an object
is detected by the RPA or RCTA
system.

Lane Departure
Warning (LDW)
If equipped, LDW may help avoid
crashes due to unintentional lane
departures. It may provide an alert if
the vehicle is crossing a lane
without using a turn signal in that
direction. LDW uses a camera
sensor to detect the lane markings
at speeds of 56 km/h (35 mph) or
greater.
{Warning
The LDW system does not steer
the vehicle. The LDW system
may not:
.Provide enough time to avoid
a crash.
.Detect lane markings under
poor weather or visibility
conditions. This can occur if
the windshield or headlamps
are blocked by dirt, snow,
or ice; if they are not in(Continued)
Warning (Continued)
proper condition; or if the sun
shines directly into the
camera.
.Detect road edges.
.Detect lanes on winding or
hilly roads.
If LDW only detects lane
markings on one side of the road,
it will only warn you when
departing the lane on the side
where it has detected a lane
marking. Always keep your
attention on the road and
maintain proper vehicle position
within the lane, or vehicle
damage, injury, or death could
occur. Always keep the
windshield, headlamps, and
camera sensors clean and in
good repair. Do not use LDW in
bad weather conditions.
How the System Works
The LDW camera sensor is on the
windshield ahead of the rearview
mirror.
To turn LDW on and off, press the
LANE DEPART button on the
steering wheel. The control indicator
will light when LDW is on.

9-46 Driving and Operating
When LDW is on,@is green if
LDW is available to warn of a lane
departure. If the vehicle crosses a
detected lane marking without using
the turn signal in that direction,
@
changes to amber and flashes.
Additionally, there will be three
beeps on the right or left, depending
on the lane departure direction.
When the System Does Not
Seem To Work Properly
The system may not detect lanes as
well when there are:
.Close vehicles ahead.
.Sudden lighting changes, such
as when driving through tunnels.
.Banked roads. If the LDW system is not functioning
properly when lane markings are
clearly visible, cleaning the
windshield may help.
LDW alerts may occur due to tar
marks, shadows, cracks in the road,
temporary or construction lane
markings, or other road
imperfections. This is normal system
operation; the vehicle does not need
service. Turn LDW off if these
conditions continue.
Fuel
Use of the recommended fuel is an
important part of the proper
maintenance of this vehicle. When
driving in the U.S. and Canada, to
help keep the engine clean and
maintain optimum vehicle
performance, we recommend using
TOP TIER Detergent Gasolines.
See www.toptiergas.com for a list of
TOP TIER Detergent Gasolines.

Mexico-7707484) - 2015 - crc - 10/1/14
Driving and Operating 9-47
If the vehicle has a yellow fuel cap,
E85 or FlexFuel can be used in the
vehicle. SeeE85 or FlexFuel on
page 9-48.
Use regular unleaded gasoline
meeting ASTM specification D4814
with a posted octane rating of 87 or
higher. Do not use gasoline with an
octane rating below 87, as it may
cause engine damage and will lower
fuel economy.
Use of Seasonal Fuels
Use summer and winter fuels in the
appropriate season. The fuels
industry automatically modifies the
fuel for the appropriate season.
If fuel is left in the vehicle tank for
long periods of time, driving or
starting could be affected. Drive the
vehicle until the fuel is at one-half
tank or less, then refuel with the
current seasonal fuel.
Prohibited Fuels
Gasolines containing oxygenates
such as ethers and ethanol, as well
as reformulated gasolines, are available in some cities. If these
gasolines comply with the
previously described specification,
then they are acceptable to use.
However, E85 (85% ethanol) and
other fuels containing more than
15% ethanol must be used only in
FlexFuel vehicles.
{Caution
Do not use fuel containing
methanol. It can corrode metal
parts in the fuel system and also
damage plastic and rubber parts.
That damage would not be
covered under the vehicle
warranty.
Some gasolines, mainly high octane
racing gasolines, can contain an
octane-enhancing additive called
methylcyclopentadienyl manganese
tricarbonyl (MMT). Do not use
gasolines and/or fuel additives with
MMT as they can reduce spark plug
life and affect emission control
system performance. The malfunction indicator lamp may turn
on. If this occurs, see your dealer
for service.
California Fuel
Requirements
If the vehicle is certified to meet
California Emissions Standards, it is
designed to operate on fuels that
meet California specifications. See
the underhood emission control
label. If this fuel is not available in
states adopting California Emissions
Standards, the vehicle will operate
satisfactorily on fuels meeting
federal specifications, but emission
control system performance might
be affected. The malfunction
indicator lamp could turn on and the
vehicle may not pass a smog-check
test. See
Malfunction Indicator
Lamp on page 5-12. If this occurs,
return to your authorized dealer for
diagnosis. If it is determined that the
condition is caused by the type of
fuel used, repairs may not be
covered by the vehicle warranty.
