•If the button is continually pushed, the set speed will
continue to decrease until the button is released, then
the new set speed will be established.
Metric Speed (km/h)
• Pushing the SET (-) button once will result in a
1 km/h decrease in set speed. Each subsequent tap of
the button results in a decrease of 1 km/h.
• If the button is continually pushed, the set speed will
continue to decrease until the button is released, then
the new set speed will be established.
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
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.
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 wind-
ing, icy, snow-covered or slippery.
REAR PARK ASSIST
The Rear Park Assist system provides audible indica-
tions of the distance between the rear fascia/bumper
and a detected obstacle when backing up, e.g. during a
parking maneuver. Refer to the “Park Assist System
Usage Precautions” for the limitations of this system
and recommendations.
The Rear Park Assist is automatically activated when
the transmission is placed into REVERSE.
Rear Park Assist Sensors
The four Rear Park Assist sensors, located in the rear
fascia/bumper, monitor the area behind the vehicle that
is within the sensors’ field of view. The sensors can
104 UNDERSTANDING THE FEATURES OF YOUR VEHICLE

detect obstacles, in the horizontal direction, from ap-
proximately 12 inches (30 cm) up to 55 inches (140 cm)
from the center of the rear fascia/bumper and up to 24
inches (60 cm) from the corners of the rear fascia/
bumper, depending on the location, type and orienta-
tion of the obstacle.
If several obstacles are detected, the Rear Park Assist
system indicates the nearest obstacle.
The minimum height of a detectable obstacle corre-
sponds to the maximum height of an obstacle that
would clear the underside of the vehicle during the
parking maneuver.Rear Park Assist Audible Alerts
If an obstacle is behind the vehicle when the transmis-
sion is placed into REVERSE, an audible alert is acti-
vated.
The tones emitted by the loudspeaker inform the driver
that the vehicle is approaching an obstacle. The pauses
between the tones are directly proportional to the
distance from the obstacle. Pulses emitted in quick
succession indicate the presence of a very close obstacle.
A continuous tone indicates that the obstacle is less than
12 inches (30 cm) away.

SIGNALMEANING INDICATION
Failure Sensor or System failures Visual Signal(instrument panel)
• Icon appears on display.
• Message is displayed on the Instrument Cluster
Display (where provided).
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 3 seconds (stopping warnings
during maneuvers parallel to walls).
Failure Indications
A malfunction of the Rear Park Assist sensors or system
is indicated, during REVERSE gear engagement, by the
instrument panel warning icon and message appearing
on the instrument cluster display. The warning icon is illuminated and a mes-
sage appears on the instrument cluster dis-
play (if equipped). Refer to Instrument Clus-
ter Display in “Understanding Your
Instrument Panel” for further information.
The sensors and wiring are tested continuously when the
ignition is in the ON/RUN position. Failures are indi-
cated 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 instrument cluster display shall
indicate that the Rear Park Assist system is unavailable,
without reference to the sensor in failure condition. If even
a single sensor fails, the entire system must be disabled.
The system is turned off automatically.
Cleaning The Rear Park Assist 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 pressure washing nozzles at least 4
inches (10 cm) from the sensors. Do not scratch or poke
the sensors. Otherwise, you could damage the sensors.
106 UNDERSTANDING THE FEATURES OF YOUR VEHICLE

Park Assist System Usage Precautions
NOTE:
•Ensure that the outer surface and the underside 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 vibrations
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 properly. 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.
WARNING!
• Drivers must be careful when backing up even
when using the Rear Park Assist system. Always
check carefully behind your vehicle, look behind
you, and be sure to check for pedestrians, ani-
mals, other vehicles, obstructions, and blind spots
before backing up. You are responsible for safety
and must continue to pay attention to your sur-
roundings. Failure to do so can result in serious
injury or death.
• Before using the Rear Park Assist System, 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 warning display turns on the single
flashing arc and 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 indication that an obstacle is
behind the vehicle.

CAUTION!
•Rear Park Assist is only a parking aid and it is
unable to recognize every obstacle, including
small obstacles. Parking curbs might be tempo-
rarily 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
Rear Park Assist 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 Rear Park Assist.
POWER SUNROOF — IF EQUIPPED
The power sunroof switch is located in the overhead
console.
WARNING!
• Never leave children alone in a vehicle, or with
access to an unlocked vehicle. Never leave the key
fob in or near the vehicle, or in a location acces-
sible to children. Occupants, particularly unat-
tended children, can become entrapped by the
power sunroof while operating the power sunroof
switch. Such entrapment may result in serious
injury or death.

Under-inflation also reduces fuel efficiency and tire
tread life, and may affect the vehicle’s handling and
stopping ability.
Please note that the TPMS is not a substitute for proper
tire maintenance, and it is the driver ’s responsibility to
maintain correct tire pressure, even if under-inflation
has not reached the level to trigger illumination of the
TPMS low tire pressure telltale.
Your vehicle has also been equipped with a TPMS
malfunction indicator to indicate when the system is
not operating properly. The TPMS malfunction indica-
tor is combined with the low tire pressure telltale. When
the system detects a malfunction, the telltale will flash
for approximately one minute and then remain continu-
ously illuminated. This sequence will continue upon
subsequent vehicle start-ups as long as the malfunction
exists. When the malfunction indicator is illuminated,
the system may not be able to detect or signal low tire
pressure as intended. TPMS malfunctions may occur for
a variety of reasons, including the installation of re-
placement or alternate tires or wheels on the vehicle
that prevent the TPMS from functioning properly. Al-
ways check the TPMS malfunction telltale after replac-
ing one or more tires or wheels on your vehicle toensure that the replacement or alternate tires and
wheels allow the TPMS to continue to function prop-
erly.
CAUTION!
The TPMS has been optimized for the original
equipment tires and wheels. TPMS pressures and
warning have been established for the tire size
equipped on your vehicle. Undesirable system op-
eration or sensor damage may result when using
replacement equipment that is not of the same size,
type, and/or style. Aftermarket wheels can cause
sensor damage. Using aftermarket tire sealants may
cause the Tire Pressure Monitoring System (TPMS)
sensor to become inoperable. After using an after-
market tire sealant it is recommended that you take
your vehicle to an authorized dealer to have your
sensor function checked.4

WARNING!
•The Brake Assist System (BAS) cannot prevent
the natural laws of physics from acting on the
vehicle, nor can it increase the traction afforded
by prevailing road conditions.
• The BAS cannot prevent collisions, including
those resulting from excessive speed in turns,
driving on very slippery surfaces, or hydroplan-
ing.
• The capabilities of a BAS-equipped vehicle must
never be exploited in a reckless or dangerous
manner which could jeopardize the user ’s safety
or the safety of others.
Traction Control System (TCS)
This system monitors the amount of wheel spin of each
of the driven wheels. If wheel spin is detected, brake
pressure is applied to the slipping wheel(s) and vehicle
power is reduced to provide enhanced acceleration and
stability. A feature of the TCS system, Brake Limited
Differential (BLD), functions similar to a limited slip
differential and controls the wheel spin across a driven
axle. If one wheel on a driven axle is spinning faster
than the other, the system will apply the brake of the spinning wheel. This will allow more torque to be
applied to the wheel that is not spinning. This feature
remains active even if TCS and ESC are in the Partial
Off mode. Refer to “Electronic Stability Control (ESC)”
in this section for further information.
Electronic Stability Control (ESC)
This system enhances directional control and stability of
the vehicle under various driving conditions. ESC cor-
rects for oversteering or understeering of the vehicle by
applying the brake of the appropriate wheel to assist in
counteracting the oversteering or understeering condi-
tion. Vehicle power may also be reduced to help the
vehicle maintain the desired path. ESC uses sensors in
the vehicle to determine the vehicle path intended by
the driver and compares it to the actual path of the
vehicle. When the actual path does not match the
intended path, ESC applies the brake of the appropriate
wheel to assist in counteracting the oversteer or under-
steer condition.
•
Oversteer - when the vehicle is turning more than
appropriate for the steering wheel position.
• Understeer - when the vehicle is turning less than
appropriate for the steering wheel position.5

CAUTION!(Continued)
operation or sensor damage may result when
using replacement equipment that is not of the
same size, type, and/or style. The TPM sensor is
not designed for use on aftermarket wheels and
may contribute to a poor overall system perfor-
mance or sensor damage. Customers are encour-
aged to use OEM wheels to assure proper TPM
feature operation.
• Using aftermarket tire sealants may cause the Tire
Pressure Monitoring System (TPMS) sensor to
become inoperable. After using an aftermarket
tire sealant it is recommended that you take your
vehicle to an authorized dealership to have your
sensor function checked.
• After inspecting or adjusting the tire pressure,
always reinstall the valve stem cap. This will
prevent moisture and dirt from entering the valve
stem, which could damage the Tire Pressure
Monitoring Sensor. NOTE:
•
The TPMS is not intended to replace normal tire care
and maintenance, or to provide warning of a tire
failure or condition.
• The TPMS should not be used as a tire pressure
gauge while adjusting your tire pressure.
• Driving on a significantly under-inflated tire causes
the tire to overheat and can lead to tire failure.
• Under-inflation also reduces the high voltage battery
range and tire tread life, and may affect the vehicle’s
handling and stopping ability.
• It is particularly important for you to check the tire
pressure in all of the tires on your vehicle monthly
and to maintain the proper pressure.
• The TPMS is not a substitute for proper tire mainte-
nance, and it is the driver ’s responsibility to maintain
correct tire pressure using an accurate tire pressure
gauge, even if under-inflation has not reached the
level to trigger illumination of the “Tire Pressure
Monitoring Telltale Light”.
• Seasonal temperature changes will affect tire pres-
sure, and the TPMS will monitor the actual tire
pressure in the tire.
