Front Passenger Seat Fold-Flat
Feature — If Equipped
To fold the seatback to the flat load-floor posi-
tion, lift the recline lever and push the seatback
forward. To return to the seating position, raise
the seatback and lock it into place.
Heated Seats — If EquippedOn some models, the front and rear seats may
be equipped with heaters in both the seat
cushions and seatbacks.
WARNING!
•Persons who are unable to feel pain to the
skin because of advanced age, chronic
illness, diabetes, spinal cord injury, medi-
cation, alcohol use, exhaustion or other
physical condition must exercise care when
using the seat heater. It may cause burns
even at low temperatures, especially if
used for long periods of time.
• Do not place anything on the seat that
insulates against heat, such as a blanket or
cushion. This may cause the seat heater to
overheat. Sitting in a seat that has been
overheated could cause serious burns due
to the increased surface temperature of the
seat.
Vehicles Equipped With Remote Start
On models that are equipped with remote start,
the driver’s heated seat can be programmed to
come on during a remote start. Refer to “Re-
mote Starting System — If Equipped” in
“Things to Know Before Starting Your Vehicle”
for further information. Front Heated Seats
There are two heated seat switches that allow
the driver and passenger to operate the seats
independently. The controls for each heater are
located near the bottom center of the instru-
ment panel (below the climate controls).
You can choose from HIGH, LOW or OFF heat
settings. Amber indicator lights in each switch
indicate the level of heat in use. Two indicator
lights will illuminate for HIGH, one for LOW and
none for OFF.
Press the switch once to select
HIGH-level heating. Press the
switch a second time to select
LOW-level heating. Press the
switch a third time to shut the heat-
ing elements OFF.
NOTE:
Once a heat setting is selected, heat will be
felt within two to five minutes.
When the HIGH-level setting is selected, the
heater will provide a boosted heat level during
the first four minutes of operation. Then, the
heat output will drop to the normal HIGH-level.
If the HIGH-level setting is selected, the system

lights on the switch will be illuminated. When
LOW speed is selected one light will be illumi-
nated.
NOTE:
The engine must be running for the venti-
lated seats to operate.
Vehicles Equipped with Remote Start
On models that are equipped with remote start,
the driver’s ventilated seat can be programmed
to come on during a remote start. Refer to
“Remote Starting System — If Equipped” in
“Things to Know Before Starting Your Vehicle”
for further information.
Head RestraintsHead restraints are designed to reduce the risk
of injury by restricting head movement in the
event of a rear-impact. Head restraints should
be adjusted so that the top of the head restraint
is located above the top of your ear.
WARNING!
The head restraints for all occupants must be
properly adjusted prior to operating the ve-
hicle or occupying a seat. Head restraints
should never be adjusted while the vehicle is
in motion. Driving a vehicle with the head
restraints improperly adjusted or removed
could cause serious injury or death in the
event of a collision.
Active Head Restraints — Front Seats
Active Head Restraints are passive, deployable
components, and vehicles with this equipment
cannot be readily identified by any markings,
only through visual inspection of the head re-
straint. The head restraint will be split in two
halves, with the front half being soft foam and
trim, the back half being decorative plastic.
When AHRs deploy during a rear impact, the
front half of the head restraint extends forward
to minimize the gap between the back of the
occupant’s head and the AHR. This system is
designed to help prevent or reduce the extent
of injuries to the driver and front passenger in
certain types of rear impacts. Refer to “Occu- pant Restraints” in “Things To Know Before
Starting Your Vehicle” for further information.
To raise the head restraint, pull upward on the
head restraint. To lower the head restraint,
press the push button, located at the base of
the head restraint, and push downward on the
head restraint.
For comfort the Active Head Restraints can be
tilted forward and rearward. To tilt the head
restraint closer to the back of your head, pull
forward on the bottom of the head restraint.
Push rearward on the bottom of the head
restraint to move the head restraint away from
your head.

WARNING!
Be sure the hood is fully latched before driving
your vehicle. If the hood is not fully latched, it
could open when the vehicle is in motion and
block your vision. Failure to follow this warn-
ing could result in serious injury or death.
LIGHTS
Headlight Switch
The headlight switch is located on the left side
of the instrument panel, next to the steering
wheel. The headlight switch controls the opera-
tion of the headlights, parking lights, instrument
panel lights, cargo lights and fog lights (if
equipped).To turn on the headlights, rotate
the headlight switch clockwise.
When the headlight switch is on
the parking lights, taillights, li-
cense plate light and instrument
panel lights are also turned on. To
turn off the headlights, rotate the headlight
switch back to the O (Off) position.
NOTE:
• Your vehicle is equipped with plastic
headlight and fog light (if equipped)
lenses that are lighter and less suscep-
tible to stone breakage than glass lights. Plastic is not as scratch resistant as glass
and therefore different lens cleaning pro-
cedures must be followed.
• To minimize the possibility of scratching
the lenses and reducing light output,
avoid wiping with a dry cloth. To remove
road dirt, wash with a mild soap solution
followed by rinsing.
CAUTION!
Do not use abrasive cleaning components,
solvents, steel wool or other abrasive materi-
als to clean the lenses.
Automatic Headlights — If EquippedThis system automatically turns the headlights
on or off according to ambient light levels. To
turn the system on, rotate the headlight switch
to the A (AUTO) position.
When the system is on, the Headlight Delay
feature is also on. This means the headlights
will stay on for up to 90 seconds after you turn
the ignition switch to the OFF position. To turn
the automatic headlights off, turn the headlight
switch out of the AUTO position.

for further information.
WARNING!
•Persons who are unable to feel pain to the
skin because of advanced age, chronic
illness, diabetes, spinal cord injury, medi-
cation, alcohol use, exhaustion, or other
physical conditions must exercise care
when using the steering wheel heater. It
may cause burns even at low tempera-
tures, especially if used for long periods.
• Do not place anything on the steering
wheel that insulates against heat, such as a
blanket or steering wheel covers of any
type and material. This may cause the
steering wheel heater to overheat.
ELECTRONIC SPEED CONTROLWhen engaged, the Electronic Speed Control
takes over accelerator operations at speeds
greater than 25 mph (40 km/h).
The Electronic Speed Control buttons are lo-
cated on the right side of the steering wheel. NOTE:
In order to ensure proper operation, the
Electronic Speed Control System has been
designed to shut down if multiple Speed
Control functions are operated at the same
time. If this occurs, the Electronic Speed
Control System can be reactivated by push-
ing the Electronic Speed Control ON/OFF
button and resetting the desired vehicle set
speed.

To ActivatePush the ON/OFF button. The Cruise Indicator
Light in the instrument cluster will illuminate. To
turn the system off, push the ON/OFF button a
second time. The Cruise Indicator Light will turn
off. The system should be turned off when not in
use.
WARNING!
Leaving the Electronic Speed Control 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 an accident. Always leave the sys-
tem OFF when you are not using it.
To Set A Desired SpeedTurn the Electronic Speed Control ON. When
the vehicle has reached the desired speed,
press the SET (-) button and release. Release
the accelerator and the vehicle will operate at
the selected speed.NOTE:
The vehicle should be traveling at a steady
speed and on level ground before pressing
the SET button.
To DeactivateA soft tap on the brake pedal, pushing the
CANCEL button, or normal brake pressure
while slowing the vehicle will deactivate Elec-
tronic Speed Control without erasing the set
speed memory. Pressing the ON/OFF button or
turning the ignition switch OFF erases the set
speed memory.
To Resume SpeedTo resume a previously set speed, push the
RES (+) button and release. Resume can be
used at any speed above 20 mph (32 km/h).
To Vary The Speed SettingWhen the Electronic Speed Control is set, you
can increase speed by pushing the RES (+)
button. If the button is continually pressed, the
set speed will continue to increase until the
button is released, then the new set speed will
be established.Pressing the RES (+) button once will result in a
1 mph (2 km/h) increase in set speed. Each
subsequent tap of the button results in an
increase of 1 mph (2 km/h).
To decrease speed while the Electronic Speed
Control is set, push the SET (-) button. If the
button is continually held in the SET (-) position,
the set speed will continue to decrease until the
button is released. Release the button when the
desired speed is reached, and the new set
speed will be established.
Pressing the SET (-) button once will result in a
1 mph (2 km/h) decrease in set speed. Each
subsequent tap of the button results in a de-
crease of 1 mph (2 km/h).
To Accelerate For PassingPress the accelerator as you would normally.
When the pedal is released, the vehicle will
return to the set speed.
Using Electronic Speed Control On Hills
The transmission may downshift on hills to
maintain the vehicle set speed.
11 6

NOTE:
The Electronic Speed Control system main-
tains speed up and down hills. A slight
speed change on moderate hills is normal.
On steep hills, a greater speed loss or gain may
occur so it may be preferable to drive without
Electronic Speed Control.
WARNING!
Electronic Speed Control can be dangerous
where the system cannot maintain a constant
speed. Your vehicle could go too fast for the
conditions, and you could lose control and
have an accident. Do not use Electronic
Speed Control in heavy traffic or on roads that
are winding, icy, snow-covered or slippery.
ADAPTIVE CRUISE CONTROL (ACC)
— IF EQUIPPED
Adaptive Cruise Control (ACC) increases the
driving convenience provided by cruise control
while traveling on highways and major road-
ways. However, it is not a safety system and not
designed to prevent collisions.
ACC will allow you to keep cruise control en-
gaged in light to moderate traffic conditions
without the constant need to reset your cruise
control. ACC utilizes a radar sensor designed
to detect a vehicle directly ahead of you.
NOTE:
•If the sensor does not detect a vehicle
ahead of you, ACC will maintain a fixed
set speed.
• If the ACC sensor detects a vehicle ahead,
ACC will apply limited braking or accel-
eration (not to exceed the original set
speed) automatically to maintain a preset
following distance, while matching the
speed of the vehicle ahead.
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
and death or serious personal injury.
• The ACC system:
Does not react to pedestrians, oncoming
vehicles, and stationary objects (e.g., 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)11 7

NOTE:
You can resume ACC from a minimum of
18 mph (30 km/h).
WARNING!
The Resume function should only be used if
traffic and road conditions permit. Resuming a
set speed that is too high or too low for
prevailing traffic and road conditions could
cause the vehicle to accelerate or decelerate
too sharply for safe operation. Failure to follow
these warnings can result in a collision and
death or serious personal injury.
To Vary The Speed SettingWhile ACC is set, you can increase the set
speed by pressing and holding the RES+
button. The increase in set speed is reflected in
the EVIC display:
While in US Mode, if the button is continually
pressed, the set speed will continue to increase
in 5 mph (8 km/h) increments. While in Metric
Mode, if the button is continually pressed, the
set speed will continue to increase in 6 mph
(10 km/h) increments. While in US Mode, pressing the RES
+button
once will result in a 1 mph (1.6 km/h) increase
in set speed. Each subsequent tap of the
button results in increase of 1 mph (1.6 km/h).
While in Metric Mode, pressing the RES +
button once will result in a 0.6 mph (1.0 km/h)
increase in set speed. Each subsequent tap of
the button results in increase of 0.6 mph
(1.0 km/h).
While ACC is set, the set speed can be de-
creased by pressing and holding the SET -
button.
If the button is held while in US Mode, the set
speed will continue to decrease in 5 mph
(8 km/h) increments.
If the button is held while in Metric Mode, the
set speed will continue to decrease in 6 mph
(10 km/h) increments.
While in US Mode, pressing the SET -button
once will result in a 1.0 mph (1.6 km/h) de-
crease in set speed. Each subsequent tap of
the button results in decrease of 1.0 mph
(1.6 km/h). While in Metric Mode, pressing the SET
-button
once will result in a 0.6 mph (1.0 km/h) de-
crease in set speed. Each subsequent tap of
the button results in decrease of 0.6 mph
(1.0 km/h).
NOTE:
• When you use the SET - button to decel-
erate, if the engine’s braking power does
not slow the vehicle sufficiently to reach
the set speed, the brake system will auto-
matically slow the vehicle.
• The ACC system can only apply a maxi-
mum of 25% of the vehicle’s braking ca-
pability and will not bring the vehicle to a
complete stop.
• The ACC system maintains set speed
when driving up hill and down hill. How-
ever, a slight speed change on moderate
hills is normal. In addition, downshifting
may occur while climbing uphill or de-
scending downhill. This is normal opera-
tion and necessary to maintain set speed.
121

The maximum braking applied by ACC is lim-
ited; however, the driver can always apply the
brakes manually, if necessary.
NOTE:
The brake lights will illuminate whenever the
ACC system applies the brakes.
A Proximity Warning will alert the driver if ACC
predicts that its maximum braking level is not
sufficient to maintain the set distance. If this
occurs, a visual alert “BRAKE” will flash in the
EVIC and a chime will sound while ACC con-
tinues to apply its maximum braking capacity.
When this occurs, you should immediately ap-
ply the brakes as needed to maintain a safe
distance from the vehicle ahead.
Adaptive Cruise Control (ACC) MenuThe EVIC displays the current ACC system
settings. The EVIC is located in the upper part
of the instrument cluster between the speed-
ometer and the tachometer. The information it
displays depends on ACC system status.Menu Button
Press the MENU button (located
on the steering wheel) repeatedly
until one of the following displays
