WARNING!(Continued)
• Allowing children to be in a vehicle unat-
tended is dangerous for a number of rea-
sons. A child or others could be seriously or
fatally injured. Children should be warned
not to touch the parking brake, brake pedal
or the shift lever.
• Do not leave the key fob in or near the
vehicle, and do not leave Keyless Enter-
N-Go in the ACC or ON/RUN mode. A child
could operate power windows, other con-
trols, or move the vehicle.
• Do not leave children or animals inside
parked vehicles in hot weather. Interior
heat build-up may cause serious injury or
death.
CAUTION!
An unlocked car is an invitation to thieves.
Always remove Key Fob from the ignition and
lock all doors when leaving the vehicle unat-
tended.
Key-In-Ignition ReminderOpening the driver’s door when the Key Fob is
in the ignition and the ignition switch position is
OFF or ACC, sounds a signal to remind you to
remove the Key Fob.
NOTE:
The Key-In-Ignition reminder only sounds
when the Key Fob is placed in the OFF or
ACC ignition position.
With the Keyless Enter-N-Go feature, opening
the driver’s door when the vehicle’s ignition
switch is placed in ACC or ON/RUN (engine
stopped) will cause the reminder chime to
sound. Refer to “Starting Procedures” in “Start-
ing And Operating” for further information.
STEERING WHEEL LOCK — IF
EQUIPPED
Your vehicle may be equipped with a passive
electronic steering wheel lock. This lock pre-
vents steering the vehicle without the ignition
key. The steering wheel lock has six positions
(one every 60 degrees). If the steering wheel is
moved to one of these six position with the key
in the off positions, the steering wheel will lock.
To Manually Lock The Steering
Wheel
With the engine running, rotate the steering
wheel one-half revolution, turn off the engine
and remove the key. Turn the steering wheel
slightly in either direction until the lock en-
gages.
To Release The Steering Wheel LockCycle the ignition and start the engine.
NOTE:
If you turned the wheel to the right to engage
the lock, you must turn the wheel slightly to
the right to disengage it. If you turned the
wheel to the left to engage the lock, turn the
wheel slightly to the left to disengage it.
SENTRY KEYThe Sentry Key Immobilizer system prevents
unauthorized vehicle operation by disabling
the engine. The system does not need to be
armed or activated. Operation is automatic,
regardless of whether the vehicle is locked or
unlocked.

Periodic Safety Checks You Should
Make Outside The Vehicle
Tires
Examine tires for excessive tread wear and
uneven wear patterns. Check for stones, nails,
glass, or other objects lodged in the tread or
sidewall. Inspect the tread for cuts and cracks.
Inspect sidewalls for cuts, cracks and bulges.
Check the wheel nuts for tightness. Check the
tires (including spare) for proper cold inflation
pressure.Lights
Have someone observe the operation of exte-
rior lights while you work the controls. Check
turn signal and high beam indicator lights on
the instrument panel.
Door Latches
Check for positive closing, latching, and lock-
ing.
Fluid Leaks
Check area under vehicle after overnight park-
ing for fuel, engine coolant, oil, or other fluid
leaks. Also, if gasoline fumes are detected or if
fuel, power steering fluid, or brake fluid leaks
are suspected, the cause should be located
and corrected immediately.

the windshield or camera lens will cause the
system to function improperly.
Daytime Running Lights — If
Equipped
The Daytime Running Lights (low intensity)
come on whenever the engine is running, and
the transmission is not in the PARK position.
The lights will remain on until the ignition is
switched to the OFF or ACC position or the
parking brake is engaged. Also, if a turn signal
is activated, the DRL lamp on the same side of
the vehicle will turn off for the duration of the
turn signal activation. Once the turn signal is no
longer active, the DRL lamp will illuminate. The
headlight switch must be used for normal night-
time driving.
Disabling The Daytime Running Lights
To disable the Daytime Running Lights open
the hood and located the Power Distribution
Center (PDC), located on the right side of the
engine compartment.Open the PDC by pulling outward on the lock-
ing tabs (one on each side) and pulling upward
on the cover.Remove the left and right Daytime Running
Lamp relays and reinstall the PDC cover.
Automatic Headlight Leveling — HID
Headlights Only
This feature prevents the headlights from inter-
fering with the vision of oncoming drivers.
Headlight leveling automatically adjusts the
height of the headlight beam in reaction to
changes in vehicle pitch.
Headlight DelayTo aid in your exit, your vehicle is equipped with
a headlight delay that will leave the headlights
on for approximately 90 seconds. This delay is

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
in the EVIC:
Adaptive Cruise Control Off When ACC is deactivated, the display willread “Adaptive Cruise Control Off.”
Adaptive Cruise Control Ready When ACC is activated but the vehiclespeed setting has not been selected, the
display will read “Adaptive Cruise Control
Ready.”
ACC SET When ACC is set, the set speed willdisplay.

13. Seat Belt Reminder LightWhen the ignition switch is first turned
to ON/RUN, this light will turn on for
four to eight seconds as a bulb check.
During the bulb check, if the driver or
front passenger’s seat belt is unbuckled, a
chime will sound. After the bulb check or when
driving, if the driver or front passenger seat belt
remains unbuckled, the Seat Belt Indicator
Light will flash or remain on continuously. Refer
to “Occupant Restraints” in “Things To Know
Before Starting Your Vehicle” for further infor-
mation.
14. Brake Warning Light This light monitors various brake
functions, including brake fluid
level and parking brake applica-
tion. If the brake light turns on it
may indicate that the parking
brake is applied, that the brake
fluid level is low, or that there is a problem with
the anti-lock brake system reservoir.
If the light remains on when the parking brake
has been disengaged, and the fluid level is at
the full mark on the master cylinder reservoir, it
indicates a possible brake hydraulic system malfunction or that a problem with the Brake
Booster has been detected by the Anti-Lock
Brake System (ABS) / Electronic Stability Pro-
gram (ESP) system. In this case, the light will
remain on until the condition has been cor-
rected. If the problem is related to the brake
booster, the ABS pump will run when applying
the brake and a brake pedal pulsation may be
felt during each stop.
The dual brake system provides a reserve
braking capacity in the event of a failure to a
portion of the hydraulic system. A leak in either
half of the dual brake system is indicated by the
Brake Warning Light, which will turn on when
the brake fluid level in the master cylinder has
dropped below a specified level.
The light will remain on until the cause is
corrected.
NOTE:
The light may flash momentarily during
sharp cornering maneuvers, which change
fluid level conditions. The vehicle should
have service performed, and the brake fluid
level checked.
If brake failure is indicated, immediate repair is
necessary.
WARNING!
Driving a vehicle with the red brake light on is
dangerous. Part of the brake system may
have failed. It will take longer to stop the
vehicle. You could have a collision. Have the
vehicle checked immediately.
Vehicles equipped with the Anti-Lock Brake
System (ABS), are also equipped with Elec-
tronic Brake Force Distribution (EBD). In the
event of an EBD failure, the Brake Warning
Light will turn on along with the ABS Light.
Immediate repair to the ABS system is re-
quired.
Operation of the Brake Warning Light can be
checked by turning the ignition switch from the
OFF position to the ON/RUN position. The light
should illuminate for approximately two sec-
onds. The light should then turn off unless the
parking brake is applied or a brake fault is
detected. If the light does not illuminate, have
the light inspected by an authorized dealer.
162

The light also will turn on when the parking
brake is applied with the ignition switch in the
ON/RUN position.
NOTE:
This light shows only that the parking brake
is applied. It does not show the degree of
brake application.
15. Anti-Lock Brake (ABS) LightThis light monitors the Anti-Lock
Brake System (ABS). The light will
turn on when the ignition switch is
turned to the ON/RUN position and
may stay on for as long as four
seconds.
If the ABS light remains on or turns on while
driving, it indicates that the Anti-Lock portion of
the brake system is not functioning and that
service is required. However, the conventional
brake system will continue to operate normally
if the BRAKE warning light is not on.
If the ABS light is on, the brake system should
be serviced as soon as possible to restore the
benefits of Anti-Lock brakes. If the ABS light
does not turn on when the ignition switch is turned to the ON/RUN position, have the light
inspected by an authorized dealer.
16. 4 LOW
This light alerts the driver that the
vehicle is in the four-wheel drive
LOW mode. The front and rear
driveshafts are mechanically
locked together forcing the front
and rear wheels to rotate at the
same speed. Low range provides a greater
gear reduction ratio to provide increased
torque at the wheels.
For further information on four-wheel drive op-
eration and proper use, refer to “Four-Wheel
Drive Operation — If Equipped” in “Starting
And Operating”.
17. Speedometer
Indicates vehicle speed.
18. Fuel Door Reminder The fuel pump symbol points to the
side of the vehicle where the fuel
door is located. 19. Fuel Gauge
The pointer shows the level of fuel in the fuel
tank when the ignition switch is in the ON/RUN
position.
