Illuminated Vanity MirrorsTo access an illuminated vanity mirror, flip down
one of the visors.
Lift the cover to reveal the mirror. The light will
turn on automatically.
Sun Visor Extension — If EquippedThis feature has a pull out extension on the sun
visor for increased coverage.
BLIND SPOT MONITORING —
IF EQUIPPED
The Blind Spot Monitoring (BSM) system uses
two radar-based sensors, located inside the
rear bumper fascia, to detect Highway licens-
able vehicles (automobiles, trucks, motor-
cycles etc.) that enter the blind spot zones from
the rear/front/side of the vehicle.
When the vehicle is started, the BSM warning
light will be momentarily illuminated in both
outside rear view mirrors to let the driver know
that the system is operational. The BSM system
sensors operate when the vehicle is in anyforward gear or REVERSE and enters stand by
mode when the vehicle is in PARK.
The BSM detection zone covers approximately
one lane on both sides of the vehicle (11 ft or
3.35 m). The zone starts at the outside rear view
mirror and extends approximately 20 ft (6 m) to
the rear of the vehicle. The BSM system moni-
tors the detection zones on both sides of the
vehicle when the vehicle speed has reached
approximately 6 mph (10 km/h) or higher and
will alert the driver of vehicles in these areas.
NOTE:
•
The BSM system does NOT alert the
driver about rapidly approaching vehicles
that are outside the detection zones.
•
The BSM system detection zone DOES
NOT change if your vehicle is towing a
trailer. Therefore, visually verify the adja-
cent lane is clear for both your vehicle and
trailer before making a lane change. If the
trailer or other object (i.e., bicycle, sports
equipment) extends beyond the side of
your vehicle, this may result in the BSM
warning light remaining illuminated the
entire time the vehicle is in a forward gear.Illuminated Vanity Mirror

WARNING!
•Adaptive Cruise Control (ACC) is a conve-
nience system. It is not a substitute for
active driving involvement. It is always the
driver’s responsibility to be attentive of
road, traffic, and weather conditions, ve-
hicle speed, distance to the vehicle ahead;
and, most importantly, brake operation to
ensure safe operation of the vehicle under
all road conditions. Your complete attention
is always required while driving to maintain
safe control of your vehicle. Failure to fol-
low these warnings can result in a collision
or serious personal injury.
• The ACC system:
Does not react to pedestrians, oncoming
vehicles, and stationary objects (i.e., a
stopped vehicle in a traffic jam or a
disabled vehicle).
Cannot take street, traffic, and weather
conditions into account, and may be
limited upon adverse sight distance con-
ditions.
(Continued)WARNING!(Continued)
Does not predict the lane curvature or
the movement of preceding vehicles and
will not compensate for such changes.
Does not always fully recognize com-
plex driving conditions, which can result
in wrong or missing distance warnings.
Can only apply a maximum of 25% of
the vehicle’s braking capability, and will
not bring the vehicle to a complete stop.
WARNING!
You should switch off the ACC system:
• When driving in fog, heavy rain, heavy
snow, sleet, heavy traffic, and complex
driving situations (i.e., in highway construc-
tion zones).
• When entering a turn lane or highway off
ramp; when driving on roads that are wind-
ing, icy, snow-covered, slippery, or have
steep uphill or downhill slopes; and when
towing a trailer.
(Continued)
WARNING!(Continued)
• When circumstances do not allow safe
driving at a constant speed.
Failure to follow these warnings can result in a
collision or serious personal injury.
The Cruise Control system has two control
modes:
• Adaptive Cruise Control mode for maintain-
ing an appropriate distance between ve-
hicles.
• Normal (fixed speed) cruise control mode for
cruising at a constant preset speed. For
additional information, refer to “Normal
(Fixed Speed) Cruise Control Mode” in this
section. Note:The system will not react to
preceding vehicles. Always be aware of the
mode selected.
You can change the mode by using the Cruise
Control buttons. The two control modes func-
tion differently. Always confirm which mode is
selected.

WARNING!
Leaving the Adaptive Cruise Control (ACC)
system on when not in use is dangerous. You
could accidentally set the system or cause it
to go faster than you want. You could lose
control and have a collision. Always leave the
system off when you are not using it.
To Set a Desired ACC SpeedWhen the vehicle reaches the speed desired,
push the SET-button and release. The EVIC
will display the set speed. Remove your foot from the accelerator pedal. If
you do not, the vehicle may continue to accel-
erate beyond the set speed. If this occurs:
•
The message “DRIVER OVERRIDE” will dis-
play in the EVIC.
• The system will not be controlling the dis-
tance between your vehicle and the vehicle
ahead. The vehicle speed will only be deter-
mined by the position of the accelerator
pedal.
To CancelThe system will disable ACC without erasing
the memory if:
• You softly tap the brake pedal.
• You depress the brake pedal.
• You press the CANCEL switch.
• An Anti-Lock Brake System (ABS) event oc-
curs.
• A Trailer Sway Control (TSC) event occurs.
• If the transmission is shifted into Neutral.
• The Electronic Stability Control/Traction Con-
trol System (ESC/TCS) activates.

Precautions While Driving with ACCIn certain driving situations, ACC may have
detection issues. In these cases, ACC may
brake late or unexpectedly. The driver needs to
stay alert and may need to intervene.
Adding a Trailer Hitch
The weight of a trailer hitch may affect the
performance of ACC. If there is a noticeable
change in performance following the installa-
tion of a hitch, such as reduced detection
range, please see your authorized dealer for
service.
Offset Driving
ACC may not detect a vehicle in the same lane
that is offset from your direct line of travel. There
will not be sufficient distance to the vehicle
ahead. The offset vehicle may move in and out
of the line of travel, which can cause your
vehicle to brake or accelerate unexpectedly.Turns and Bends
In turns or bends, ACC may detect a vehicle
ahead too late or too early. This may cause your
vehicle to brake late or unexpectedly. Give
extra attention in curves and be ready to apply
the brakes if necessary. Be sure to select an
appropriate speed while driving in curves.
ACC may occasionally provide braking and/or
a driver alert that you consider unnecessary.
This may be the system’s response to signs,
guardrails, and other stationary objects in a
curve. This may also occur at the base of steep
hills. This is normal operation and your vehicle
does not require service.

•Clean the ParkSense sensors regularly,
taking care not to scratch or damage
them. The sensors must not be covered
with ice, snow, slush, mud, dirt or debris.
Failure to do so can result in the system
not working properly. The ParkSense 
system might not detect an obstacle be-
hind or in front of the fascia/bumper, or it
could provide a false indication that an
obstacle is behind or in front of the fascia/
bumper.
• Objects such as bicycle carriers, trailer
hitches, etc., must not be placed within
12 in (30 cm) from the rear fascia/bumper
while driving the vehicle. Failure to do so
can result in the system misinterpreting a
close object as a sensor problem, caus-
ing the “SERVICE PARK ASSIST SYS-
TEM” message to be displayed in the
instrument cluster.CAUTION!
• ParkSense is only a parking aid and it is
unable to recognize every obstacle, includ-
ing small obstacles. Parking curbs might be
temporarily detected or not detected at all.
Obstacles located above or below the sen-
sors will not be detected when they are in
close proximity.
• The vehicle must be driven slowly when
using ParkSense in order to be able to
stop in time when an obstacle is detected.
When backing up, it is recommended that
the driver looks over his/her shoulder when
using ParkSense .WARNING!
• Drivers must be careful when backing up
even when using the ParkSense Park
Assist System. Always check carefully be-
hind your vehicle, look behind you, and be
sure to check for pedestrians, animals,
other vehicles, obstructions, and blind
spots before backing up. You are respon-
sible for safety and must continue to pay
attention to your surroundings. Failure to
do so can result in serious injury or death.

23. Electronic Stability Control (ESC) OFF
Indicator Light — If EquippedThis light indicates the Electronic
Stability Control (ESC) is off.
24. Vehicle Security Light This light will flash rapidly for ap-
proximately 15 seconds when the
vehicle theft alarm is arming. The
light will flash at a slower speed
continuously after the alarm is set.
The security light will also come on
for about three seconds when the ignition is first
turned on.
25. Temperature Gauge
The temperature gauge shows engine coolant
temperature. Any reading within the normal
range indicates that the engine cooling system
is operating satisfactorily.
The gauge pointer will likely indicate a higher
temperature when driving in hot weather, up
mountain grades, or when towing a trailer. It should not be allowed to exceed the upper
limits of the normal operating range.
CAUTION!
Driving with a hot engine cooling system could
damage your vehicle. If the temperature
gauge reads “H” pull over and stop the ve-
hicle. Idle the vehicle with the air conditioner
turned off until the pointer drops back into the
normal range. If the pointer remains on the “H”
and you hear continuous chimes, turn the
engine off immediately, and call an authorized
dealership for service.
WARNING!
A hot engine cooling system is dangerous.
You or others could be badly burned by steam
or boiling coolant. You may want to call an
authorized dealership for service if your ve-
hicle overheats. If you decide to look under
the hood yourself, see “Maintaining Your Ve-
hicle”. Follow the warnings under the Cooling
System Pressure Cap paragraph.26. Rear Fog Light Indicator
This indicator will illuminate when the
rear fog lights are on.

non-essential electrical devices or increase en-
gine speed (if at idle). If the charging system
light remains on, it means that the vehicle is
experiencing a problem with the charging sys-
tem. Obtain SERVICE IMMEDIATELY. See an
authorized dealer.
If jump starting is required, refer to “Jump
Starting Procedures” in “What To Do In Emer-
gencies”.
•Electronic Throttle Control (ETC) Light
This light informs you of a problem
with the Electronic Throttle Control
(ETC) system. The light will come
on when the ignition is first turned
ON and remain on briefly as a bulb
check. If the light does not come
on during starting, have the system checked by
an authorized dealer.
If a problem is detected, the light will come on
while the engine is running. Cycle the ignition
key when the vehicle has completely stopped
and the shift lever is placed in the PARK
position. The light should turn off.
If the light remains lit with the engine running
your vehicle, will usually be drivable, however, see an authorized dealer for service as soon as
possible. If the light is flashing when the engine
is running, immediate service is required and
you may experience reduced performance, an
elevated/rough idle or engine stall and your
vehicle may require towing.
•
Engine Temperature Warning Light
This light warns of an overheated en-
gine condition. As temperatures rise
and the gauge approaches H,this
indicator will illuminate and a single
chime will sound after reaching a set threshold.
Further overheating will cause the temperature
gauge to pass H,the indicator will continuously
flash and a continuous chime will occur until
the engine is allowed to cool.
If the light turns on while driving, safely pull
over and stop the vehicle. If the A/C system is
on, turn it off. Also, shift the transmission into
NEUTRAL and idle the vehicle. If the tempera-
ture reading does not return to normal, turn the
engine off immediately and call for service.
Refer to “If Your Engine Overheats” in “What To
Do In Emergencies” for more information. •
Transmission Temperature Light
This light indicates that there is
excessive transmission fluid tem-
perature that might occur with se-
vere usage such as trailer towing.
It may also occur when operating
the vehicle in a high torque con-
verter slip condition, such as 4-wheel-drive
operation (e.g., snow plowing, off- road opera-
tion). If this light comes on, stop the vehicle and
run the engine at idle or faster, with the trans-
mission in NEUTRAL until the light goes off.
CAUTION!
Continuous driving with the Transmission
Temperature Indicator illuminated will eventu-
ally cause severe transmission damage or
transmission failure.

Operating Tips
Window Fogging
Windows will fog on the inside when the humid-
ity inside the vehicle is high. This often occurs
in mild or cool temperatures when it’s rainy or
humid. In most cases, turning the air condition-
ing (pressing the A/C button) on will clear the
fog. Adjust the temperature control, air direc-
tion, and blower speed to maintain comfort.
As the temperature gets colder, it may be
necessary to direct air onto the windshield.
Adjust the temperature control and blower
speed to maintain comfort. Higher blower
speeds will reduce fogging. Interior fogging on
the windshield can be quickly removed by
selecting the DEFROST mode.Regular cleaning of the inside of the windows
with a non-filming cleaning solution (vinegar
and water works very well) will help prevent
contaminates (cigarette smoke, perfumes, etc.)
from sticking to the windows. Contaminates
increase the rate of window fogging.
Summer Operation
NOTE:
In some cases during high temperature
trailer tow operation the Air Conditioning
system performance may be reduced. This
is to help protect the engine from overheat-
ing during the high load condition.
Your air conditioning system is also equipped
with an automatic recirculation system. When
the system senses a heavy load or high heat
conditions, it may use partial Recirculation A/C
mode to provide additional comfort.Winter Operation
When operating the system during the winter
months, make sure the air intake, located di-
rectly in front of the windshield, is free of ice,
slush, snow, or other obstructions.
Vacation Storage
Anytime you store your vehicle, or keep it out of
service (i.e. vacation) for two weeks or more,
run the air conditioning system at idle for about
five minutes in the fresh air and high blower
setting. This will ensure adequate system lubri-
cation to minimize the possibility of compressor
damage when the system is started again.
