STARTING AND OPERATING 345
To Set A Desired ACC Speed
When the vehicle reaches the speed desired, push the SET (+)
button or the SET (-) button and release. The instrument
cluster display will show the set speed.
If the system is set when the vehicle speed is below 20 mph
(32 km/h), the set speed shall be defaulted to 20 mph
(32 km/h). If the system is set when the vehicle speed is
above 20 mph (32 km/h), the set speed shall be the current
speed of the vehicle.
NOTE:
ACC cannot be set if there is a stationary vehicle in front of
your vehicle in close proximity.
Remove your foot from the accelerator pedal, after the ACC
has been set. If you do not, the vehicle may continue to accel -
erate beyond the set speed. If this occurs:
• The message “ACC DRIVER OVERRIDE” will display in the instrument cluster display.
• The system will not be controlling the distance between your vehicle and the vehicle ahead. The vehicle speed will
only be determined by the position of the accelerator
pedal.
To Cancel
The following conditions cancel the system:
• The brake pedal is applied.
• The CANC (cancel) button is pushed.
• An Anti-Lock Brake System (ABS) event occurs.
• The trailer brake is applied manually (if equipped).
• The gear selector is removed from the DRIVE position.
• The Electronic Stability Control/Traction Control System(ESC/TCS) activates.
• The vehicle parking brake is applied.
• Driver seatbelt is unbuckled at low speeds.
• Driver door is opened at low speeds.
• A Trailer Sway Control (TSC) event occurs.
• The driver switches ESC to Full Off mode.

STARTING AND OPERATING 371
PARKSENSE ACTIVE PARK ASSIST SYSTEM — IF
EQUIPPED
The ParkSense Active Park Assist system is intended to assist
the driver during parallel and perpendicular parking
maneuvers by identifying a proper parking space, providing
audible/visual instructions, and controlling the steering
wheel. The ParkSense Active Park Assist system is defined as
“semi-automatic” since the driver maintains control of the
accelerator, gear selector and brakes. Depending on the
driver's parking maneuver selection, the ParkSense ActivePark Assist system is capable of maneuvering a vehicle into
a parallel or a perpendicular parking space on either side
(i.e., driver side or passenger side).
NOTE:
• The driver is always responsible for controlling the
vehicle, responsible for any surrounding objects, and must
intervene as required.
• The system is provided to assist the driver and not to substitute the driver.
• During a semi-automatic maneuver, if the driver touches the steering wheel after being instructed to remove their
hands from the steering wheel, the system will cancel, and
the driver will be required to manually complete the
parking maneuver.
• The system may not work in all conditions (e.g. environ -
mental conditions such as heavy rain, snow, etc., or if
searching for a parking space that has surfaces that will
absorb the ultrasonic sensor waves).
• New vehicles from the dealership must have at least 30 miles (48 km) accumulated before the ParkSense Active
Park Assist system is fully calibrated and performs accu -
rately. This is due to the system’s dynamic vehicle calibra -
CAUTION!
• ParkSense is only a parking aid and it is unable to recognize every obstacle, including small obstacles.
Parking curbs might be temporarily detected or not
detected at all. Obstacles located above or below the
sensors will not be detected when they are in close
proximity.
• The vehicle must be driven slowly when using Park -
Sense in order to be able to stop in time when an
obstacle is detected. It is recommended that the driver
looks over his/her shoulder when using ParkSense.

Automatic Transmission
Selection Of Lubricant
It is important to use the proper transmission fluid to ensure
optimum transmission performance and life. Use only the
manufacturer’s specified transmission fluid. Refer to “Fluids
And Lubricants” in “Technical Specifications”. It is
important to maintain the transmission fluid at the correct
level using the recommended fluid. No chemical flushes
should be used in any transmission; only the approved lubri-
cant should be used.
WARNING!
• Use only manufacturer's recommended brake fluid. Refer to “Fluids And Lubricants” in “Technical Speci -
fications” for further information. Using the wrong
type of brake fluid can severely damage your brake
system and/or impair its performance. The proper type
of brake fluid for your vehicle is also identified on the
original factory installed hydraulic master cylinder
reservoir.
• To avoid contamination from foreign matter or mois -
ture, use only new brake fluid or fluid that has been in
a tightly closed container. Keep the master cylinder
reservoir cap secured at all times. Brake fluid in a open
container absorbs moisture from the air resulting in a
lower boiling point. This may cause it to boil unexpect -
edly during hard or prolonged braking, resulting in
sudden brake failure. This could result in a collision.
• Overfilling the brake fluid reservoir can result in spilling brake fluid on hot engine parts, causing the
brake fluid to catch fire. Brake fluid can also damage
painted and vinyl surfaces, care should be taken to
avoid its contact with these surfaces.
• Do not allow petroleum based fluid to contaminate thebrake fluid. Brake seal components could be damaged,
causing partial or complete brake failure. This could
result in a collision.
CAUTION!
Using a transmission fluid other than the manufacturer’s
recommended fluid may cause deterioration in
transmission shift quality and/or torque converter
shudder. Refer to “Fluids And Lubricants” in “Technical
Specifications” for fluid specifications.

NOTE:
• P (Passenger) — Metric tire sizing is based on US designstandards. P-Metric tires have the letter “P” molded into
the sidewall preceding the size designation. Example:
P215/65R15 95H.
• European — Metric tire sizing is based on European design standards. Tires designed to this standard have the
tire size molded into the sidewall beginning with the
section width. The letter "P" is absent from this tire size
designation. Example: 215/65R15 96H.
• LT (Light Truck) — Metric tire sizing is based on US design standards. The size designation for LT-Metric tires is the same as for P-Metric tires except for the letters “LT” that
are molded into the sidewall preceding the size designa
-
tion. Example: LT235/85R16.
• Temporary spare tires are designed for temporary emer -
gency use only. Temporary high pressure compact spare
tires have the letter “T” or “S” molded into the sidewall
preceding the size designation. Example: T145/80D18

Tire Identification Number (TIN)
The Tire Identification Number (TIN) may be found on one or both sides of the tire; however, the date code may only be on
one side. Tires with white sidewalls will have the full TIN, including the date code, located on the white sidewall side of the
tire. Look for the TIN on the outboard side of black sidewall tires as mounted on the vehicle. If the TIN is not found on the
outboard side, then you will find it on the inboard side of the tire.Load Identification:
Absence of the following load identification symbols on the sidewall of the tire indicates a Standard Load (SL) tire:
•
XL = Extra load (or reinforced) tire, or
• LL = Light load tire or
• C, D, E, F, G = Load range associated with the maximum load a tire can carry at a specified pressure
Maximum Load – Maximum load indicates the maximum load this tire is designed to carry
Maximum Pressure – Maximum pressure indicates the maximum permissible cold tire inflation pressure for this tire EXAMPLE:
EXAMPLE:
DOT MA L9 ABCD 0301
DOT = Department of Transportation
• This symbol certifies that the tire is in compliance with the US Department of Transportation tire safety standards and is approved for highway use
MA = Code representing the tire manufacturing location (two digits)
L9 = Code representing the tire size (two digits)

TECHNICAL SPECIFICATIONS
IDENTIFICATION DATA
Vehicle Identification Number
The Vehicle Identification Number (VIN) is found on the left
front corner of the instrument panel, visible through the
windshield. This number also appears on the vehicle frame
etched on right hand center rail, as well as the Automobile
Information Disclosure Label affixed to a window on your
vehicle, the vehicle registration and title.Vehicle Identification Number
NOTE:
It is illegal to remove or alter the VIN.
BRAKE SYSTEM
If power assist is lost for any reason (for example, repeated
brake applications with the engine off), the brakes will still
function. However, you will experience a substantial
increase in braking effort to stop the vehicle.
If either the front or rear hydraulic system loses normal
braking capability, the remaining system will still function
with some loss of overall braking effectiveness. This will be
evident by increased pedal travel during application, greater
pedal force required to slow or stop, and activation of the
“Brake Warning Light” and the “ABS Warning Light” (if
equipped) during brake use.
WHEEL AND TIRE TORQUE SPECIFICATIONS
Proper lug nut/bolt torque is very important to ensure that
the wheel is properly mounted to the vehicle. Any time a
wheel has been removed and reinstalled on the vehicle, the
lug nuts/bolts should be torqued using a properly calibrated
torque wrench using a high quality six sided (hex) deep wall
socket.
