AUTOMATIC TRANSMISSION
Do not leave the key fob in or near the
vehicle, or in a location accessible to chil-
dren, and do not leave a vehicle equipped
with Keyless Enter-N-Go in the ACC or ON/
RUN mode. A child could operate power
windows, other controls, or move the
vehicle.
Be sure the parking brake is fully disen -
gaged before driving; failure to do so can
lead to brake failure and a collision.
Always fully apply the parking brake when
leaving your vehicle or it may roll and cause
damage or injury. Also, be certain to leave
the transmission in PARK. Failure to do so
may cause the vehicle to roll and cause
damage or injury.
CAUTION!
If the Brake System Warning Light remains on
with the parking brake released, a brake
system malfunction is indicated. Have the
brake system serviced by an authorized
dealer immediately.
WARNING!
(Continued)

WARNING!
It is dangerous to shift out of PARK or
NEUTRAL if the engine speed is higher than
idle speed. If your foot is not firmly pressing
the brake pedal, the vehicle could accel -
erate quickly forward or in reverse. You
could lose control of the vehicle and hit
someone or something. Only shift into gear
when the engine is idling normally and your
foot is firmly pressing the brake pedal.
Unintended movement of a vehicle could
injure those in or near the vehicle. As with
all vehicles, you should never exit a vehicle
while the engine is running. Before exiting a
vehicle always come to a complete stop,
then apply the parking brake, shift the
transmission into PARK, turn the engine
OFF, and remove the ignition key. Once the
key is removed, the transmission is locked
in PARK, securing the vehicle against
unwanted movement.
When leaving the vehicle, always remove
the ignition key from the vehicle and lock
the vehicle.
Never leave children alone in a vehicle, or
with access to an unlocked vehicle.
Allowing children to be in a vehicle unat -
tended is dangerous for a number of
reasons. A child or others could be seriously
or fatally injured. Children should be
warned not to touch the parking brake,
brake pedal or the transmission gear
selector.
Do not leave the ignition key in or near the
vehicle (or in a location accessible to chil -
dren). A child could operate power
windows, other controls, or move the
vehicle.

100STARTING AND OPERATING
Transmission Limp Home Mode
Transmission function is monitored electroni -
cally for abnormal conditions. If a condition is
detected that could result in transmission
damage, Transmission Limp Home Mode is acti -
vated. In this mode, the transmission remains
in third gear regardless of which forward gear is
selected. PARK, REVERSE, and NEUTRAL will
continue to operate. The Malfunction Indicator
Light (MIL) may be illuminated. Transmission
Limp Home Mode allows the vehicle to be
driven to an authorized dealer for service
without damaging the transmission. In the event of a momentary problem, the trans
-
mission can be reset to regain all forward gears
by performing the following steps:
1. Stop the vehicle.
2. Shift the transmission into PARK.
3. Turn the ignition OFF.
4. Wait approximately 10 seconds.
5. Restart the engine.
6. Shift into the desired gear range. If the problem is no longer detected, the trans -
mission will return to normal operation.
NOTE:
Even if the transmission can be reset, we
recommend that you visit your authorized
dealer at your earliest possible convenience.
Your authorized dealer has diagnostic equip -
ment to assess the condition of your transmis -
sion.
If the transmission cannot be reset, authorized
dealer service is required.
Electronic Range Select (ERS) Operation
The Electronic Range Select (ERS) shift control
allows the driver to limit the highest available
gear. For example, if you set the transmission
gear limit to 4 (fourth gear), the transmission
will not shift above fourth gear, but will shift
through the lower gears normally.
You can switch between DRIVE and ERS mode
at any vehicle speed. When the gear selector is
in the DRIVE position, the transmission will
operate automatically, shifting between all
available gears. Moving the gear selector to the
ERS position (beside DRIVE) will activate ERS
mode, display the current gear in the instru -
ment cluster, and set that gear as the top avail -
able gear. Once in ERS mode, moving the gear
selector forward (-) or rearward (+) will change
the top available gear.
To exit ERS mode, simply return the gear
selector to the DRIVE position.
WARNING!
Do not downshift for additional engine
braking on a slippery surface. The drive
wheels could lose their grip and the vehicle
could skid, causing a collision or personal
injury.

STARTING AND OPERATING103
Power Steering Fluid Check
Checking the power steering fluid level at a
defined service interval is not required. The fluid
should be checked at every oil change if a leak
is suspected, abnormal noises are apparent,
and/or the system is not functioning as antici -
pated. Coordinate inspection efforts through an
authorized dealer. If necessary, add fluid to restore to the proper
indicated level. With a clean cloth, wipe any
spilled fluid from all surfaces. Refer to “Fluids
And Lubricants” in “Technical Specifications”
for further information.
SPEED CONTROL — IF EQUIPPED
When engaged, the Speed Control takes over
accelerator operations at speeds greater than
25 mph (40 km/h) up to the maximum speed of
100 mph (160 km/h).
The Speed Control lever is located on the left
side of the steering column.
Speed Control Lever NOTE:
In order to ensure proper operation, the Speed
Control system has been designed to shut down
if multiple Speed Control functions are operated
at the same time. If this occurs, the Speed
Control system can be reactivated by rotating
the Speed Control ON/OFF center ring and
resetting the desired vehicle set speed.
To Activate
Rotate the center ring upward on the Speed
Control lever to turn the system on. The Cruise
Indicator Light in the instrument cluster display
will illuminate. To turn the system off, rotate the
center ring upward a second time. The Cruise
Indicator Light will turn off. The system should
be turned off when not in use.WARNING!
Fluid level should be checked on a level
surface and with the engine off to prevent
injury from moving parts and to ensure
accurate fluid level reading. Do not overfill.
Use only manufacturer's recommended
power steering fluid.
CAUTION!
Do not use chemical flushes in your power
steering system as the chemicals can
damage your power steering components.
Such damage is not covered by the New
Vehicle Limited Warranty.
WARNING!
Leaving the 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
system off when you are not using it.

STARTING AND OPERATING105
To Accelerate For Passing
Press the accelerator as you would normally.
When the pedal is released, the vehicle will
return to the set speed.
Using Speed Control On Hills
The transmission may downshift on hills to
maintain the vehicle set speed.
NOTE:
The Speed Control system maintains 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
Speed Control.
To Resume Speed
To resume a previously set speed, push the RES
button and release. Resume can be used at any
speed above 20 mph (32 km/h) up to the
maximum speed of 100 mph (160 km/h).
To Deactivate
A soft tap on the brake pedal, pushing the RES
button, or normal brake pressure while slowing
the vehicle will deactivate Speed Control
without erasing the set speed memory. Rotating
the center ring upward to turn the system off or
placing the ignition in the STOP (OFF/LOCK)
position erases the set speed memory.
PARKSENSE REAR PARK ASSIST — IF
EQUIPPED
The ParkSense Rear Park Assist system
provides an audible indication of the distance
between the rear fascia/bumper and a
detected obstacle when backing up (e.g. during
a parking maneuver). Refer to “ParkSense
System Usage Precautions” in this section for
limitations of this system and recommenda -
tions.
The ParkSense Rear Park Assist is automati -
cally activated when the transmission is placed
into REVERSE. As the distance from an obstacle
behind the vehicle decreases, the audible alert
becomes more frequent.
Interaction With Trailer Towing
The Rear Park Assist system is automatically
deactivated when a trailer is hitched to the
vehicle. The system will be automatically acti -
vated as soon as the trailer is removed.
WARNING!
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 Speed Control
in heavy traffic or on roads that are winding,
icy, snow-covered or slippery.

108STARTING AND OPERATING
While audible signals are emitted, the audio
system is not muted.
The audible signal is turned off immediately if
the distance increases. The tone cycle remains
constant if the distance measured by the inner
sensors is constant. If this condition occurs for
the external sensors, the signal is turned off
after three seconds (stopping warnings during
maneuvers parallel to walls).
ParkSense Rear Park Assist Failure
Indications
A malfunction of the ParkSense Rear Park
Assist sensors or system is indicated, during
REVERSE gear engagement, by the instrument
panel warning icon.
The warning icon is illuminated and a
message is displayed in the instru -
ment cluster display (if equipped).
Refer to “Warning Lights And
Messages” in “Getting To Know Your Instru -
ment Panel” for further information.
The sensors and wiring are tested continuously
when the ignition is in the MAR (ACC/ON/RUN)
position. Failures are indicated immediately if
they occur when the system is on. Even if the system is able to identify that a
specific sensor is in failure condition, the instru
-
ment cluster display shall indicate that the Park-
Sense Rear Park Assist system is unavailable,
without reference to the sensor in failure condi -
tion. If even a single sensor fails, the entire
system must be disabled. The system is turned
off automatically.
Cleaning The ParkSense System
Clean the Rear Park Assist sensors with water,
car wash soap and a soft cloth. Do not use
rough or hard cloths. In washing stations, clean
sensors quickly keeping the vapor jet/high pres -
sure washing nozzles at least 4 inches (10 cm)
from the sensors. Do not scratch or poke the
sensors. Otherwise, you could damage the
sensors.
ParkSense Rear Park Assist System Usage
Precautions
NOTE:
Ensure that the outer surface and the under -
side of the rear bumper is clean and clear of
snow, ice, mud, dirt or other obstruction to
keep the Rear Park Assist system operating
properly.
Jackhammers, large trucks, and other vibra -
tions could affect the performance of Rear
Park Assist.
Clean the Rear Park Assist 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 prop -
erly. The Rear Park Assist system might not
detect an obstacle behind the fascia/
bumper, or it could provide a false indication
that an obstacle is behind the fascia/
bumper.
Objects such as bicycle carriers, etc., must
not be placed within 12 inches (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, causing a failure indication
to be displayed in the instrument cluster
display.

STARTING AND OPERATING109
If it’s necessary to keep the ball mount and
hitch ball assembly mounted for a long period,
it is possible to filter out the ball mount and
hitch ball assembly presence in sensor field of
view. The filtering operation must be performed
only by an authorized dealer.
PARKVIEW REAR BACK UP CAMERA
Your vehicle is equipped with the ParkView Rear
Back Up Camera that allows you to see an
on-screen image of the rear surroundings of
your vehicle whenever the gear selector is put
into REVERSE and/or when the rear doors are opened. The image will be displayed on the
touchscreen display along with a caution note
to “check entire surroundings” across the top of
the screen. After five seconds this note will
disappear. The ParkView Rear Back Up Camera
is located on the top rear of the vehicle below
the center light.
Rear Back Up Camera Location
When the vehicle is shifted out of REVERSE
and/or when the rear doors are closed, the rear
camera mode is exited and the navigation or
audio screen appears again.
WARNING!
Drivers must be careful when backing up
even when using ParkSense. Always check
carefully behind your vehicle, look behind
you, and be sure to check for pedestrians,
animals, other vehicles, obstructions, and
blind spots before backing up. You are
responsible for safety and must continue to
pay attention to your surroundings. Failure
to do so can result in serious injury or
death.
Before using ParkSense, it is strongly
recommended that the ball mount and
hitch ball assembly is disconnected from
the vehicle when the vehicle is not used for
towing. Failure to do so can result in injury
or damage to vehicles or obstacles
because the hitch ball will be much closer
to the obstacle than the rear fascia when
the loudspeaker sounds the continuous
tone. Also, the sensors could detect the ball
mount and hitch ball assembly, depending
on its size and shape, giving a false indica -
tion that an obstacle is behind the vehicle.
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 ParkSense 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.

REFUELING THE VEHICLE
The gas cap is located behind the fuel filler door
on the left side of the vehicle. If the gas cap is
lost or damaged, be sure the replacement cap
is for use with this vehicle.
Fuel Filler
NOTE:
During fuel fill, nozzle position could affect the
flow of fuel. For best results, allow the nozzle to
rest naturally in the filler tube - do not raise the
handle to increase the fill angle. NOTE:When the fuel nozzle “clicks” or shuts off, the
fuel tank is full.
Tighten the fuel filler cap until you hear a
“clicking” sound. This is an indication that the
fuel filler cap is properly tightened.
If the gas cap is not tightened properly, the
MIL may come on. Be sure the gas cap is
tightened every time the vehicle is refueled.
Loose Fuel Filler Cap Message
If the vehicle diagnostic system determines that
the fuel filler cap is loose, improperly installed,
or damaged, a “Check fuel cap” message will be
displayed in the instrument cluster display.
Refer to “Instrument Cluster Display” in
“Getting To Know Your Instrument Panel” for
further information. Tighten the fuel filler cap
until a “clicking” sound is heard. This is an indi
-
cation that the fuel filler cap is properly tight -
ened. Refer to “Onboard Diagnostic System” in
“Getting To Know Your Instrument Panel” for
further information.
If the problem continues, the message will
appear the next time the vehicle is started. See
your authorized dealer as soon as possible.
WARNING!
Never have any smoking materials lit in or
near the vehicle when the fuel door is open
or the tank is being filled.
Never add fuel when the engine is running.
This is in violation of most state and federal
fire regulations and may cause the
“Malfunction Indicator Light” to turn on.
A fire may result if fuel is pumped into a
portable container that is inside of a
vehicle. You could be burned. Always place
fuel containers on the ground while filling.
CAUTION!
Damage to the fuel system or emissions
control system could result from using an
improper fuel tank filler tube cap.
A poorly fitting fuel filler cap could let impu -
rities into the fuel system.
A poorly fitting fuel filler cap may cause the
“Malfunction Indicator Light (MIL)” to turn
on.
To avoid fuel spillage and overfilling, do not
“top off” the fuel tank after filling. When the
fuel nozzle “clicks” or shuts off, the fuel
tank is full.

Shallow Standing Water
Although your vehicle is capable of driving
through shallow standing water, consider the
following Cautions and Warnings before doing
so.
WARNING!
Driving through standing water limits your
vehicle’s traction capabilities. Do not
exceed 5 mph (8 km/h) when driving
through standing water.
Driving through standing water limits your
vehicle’s braking capabilities, which
increases stopping distances. Therefore,
after driving through standing water, drive
slowly and lightly press on the brake pedal
several times to dry the brakes.
Failure to follow these warnings may result
in injuries that are serious or fatal to you,
your passengers, and others around you.
CAUTION!
Always check the depth of the standing
water before driving through it. Never drive
through standing water that is deeper than
the bottom of the tire rims mounted on the
vehicle.
Determine the condition of the road or the
path that is under water and if there are any
obstacles in the way before driving through
the standing water.
Do not exceed 5 mph (8 km/h) when
driving through standing water. This will
minimize wave effects.
Driving through standing water may cause
damage to your vehicle’s drivetrain compo -
nents. Always inspect your vehicle’s fluids
(i.e., engine oil, transmission, axle, etc.) for
signs of contamination (i.e., fluid that is
milky or foamy in appearance) after driving
through standing water. Do not continue to
operate the vehicle if any fluid appears
contaminated, as this may result in further
damage. Such damage is not covered by
the New Vehicle Limited Warranty.
Getting water inside your vehicle’s engine
can cause it to lock up and stall out, and
cause serious internal damage to the
engine. Such damage is not covered by the
New Vehicle Limited Warranty.
CAUTION!
