Metric Speed (km/h)
Pushing the SET switch once will result in a
1 km/h speed adjustment. Each subse -
quent movement of the switch results in an
adjustment of 1 km/h.
If the switch is continually pushed, the set
speed will continue to adjust until the switch
is released, then the new set speed will be
established.

NOTE:

Moving the SET switch allows for adjusting of
the speed according to the selected unit of
measurement set on the radio system. Refer
to the Information and Entertainment System
Owner’s Manual for more information.
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 Cruise Control On Hills
The transmission may downshift on hills to
maintain the vehicle set speed.

NOTE:

The Cruise 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 Cruise 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).

NOTE:

Before resuming the previously set speed, you
must accelerate to a speed close to that
speed.
Resume Button Location
In AutoStick (sequential) mode, before
resuming the previously set speed, you should
accelerate until you are close to that speed.
Then, push and release the RES button.
To Deactivate
A tap on the brake pedal deactivates the
Cruise Control without deleting the set speed.
The Cruise Control may also be deactivated by
applying the Electric Park Brake or when the
braking system is operated (e.g. operation of
the Electronic Stability Control (ESC) system).
The set speed is deleted in the following
cases:
Pushing the on/off button a second time
The ignition is placed in the OFF position
If there is a malfunction with the Cruise
Control
Adaptive Cruise Control (ACC) — If Equipped
The Adaptive Cruise Control (ACC) is a driver
assist system that combines the Cruise
Control functions with controlling the distance
from the vehicle ahead. ACC increases the
driving convenience provided by Cruise
Control while traveling on highways and major
roadways. However, it is not a safety system
and not designed to prevent collisions. The
Cruise Control function performs differently

Ú
page 105.
ACC will allow you to keep Cruise Control
engaged in light to moderate traffic conditions
without the constant need to reset your Cruise
Control. ACC uses a radar sensor located
behind the front bumper and a camera located
in the center/upper part of the windshield, to
detect the presence of a vehicle close ahead.
WARNING!
Cruise 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 Cruise Control
in heavy traffic or on roads that are winding,
icy, snow-covered or slippery.

STARTING AND OPERATING

108

(Continued)
The system sets and holds the vehicle at the
desired speed without needing to press the
accelerator. It also sets and holds a distance
from the vehicle ahead (these settings are set
by the driver).Front Bumper Radar Location
Windshield Camera Location If the system detects a vehicle ahead, it will
automatically intervene by slightly braking or
accelerating in order to maintain the preset
distance. It will not exceed the original set
speed when adapting to the speed of the
vehicle ahead.

NOTE:

Adaptive Cruise Control performance is not
guaranteed under the following circum
-
stances, and it is recommended to turn the
system off when:
Driving in fog, heavy rain, or snow.
Driving in heavy traffic or construction
zones.
Driving on icy, snowy, slippery roads, roads
with steep inclines, or roads with numerous
turns and bends.
Entering a turn lane.
When circumstances do not allow safe
driving at a constant speed
Ú
page 273.
WARNING!
Adaptive Cruise Control (ACC) is a conve -
nience system. It is not a substitute for
active driver involvement. It is always the
driver’s responsibility to be attentive of
road, traffic, and weather conditions,
vehicle speed, distance to the vehicle
ahead; and, most importantly, brake oper -
ation 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 follow these warn -
ings can result in a collision and death or
serious personal injury.
The ACC system:
• May react to pedestrians, oncoming
vehicles, and stationary objects (e.g.,
a stopped vehicle in a traffic jam or a
disabled vehicle) at speeds between
2 mph and 35 mph (4 km/h and
60 km/h).
• Cannot take street, traffic, and
weather conditions into account, and
may be limited upon adverse sight
distance conditions.
21_GA_OM_EN_USC_t.book Page 108

111

NOTE:

Moving the RES/SET switch downward
allows you to adjust the speed according to
the selected unit of measurement ("U.S." or
"Metric") set on the radio system. Refer to
the Information and Entertainment System
Owner’s Manual Supplement for further
information.
When the unit of measurement is set to
Metric, pushing and holding the RES/SET
switch will adjust the speed in 10 km/h
increments.
By keeping the accelerator pedal pressed,
the vehicle can continue to accelerate
beyond the set speed. In this case, use the
RES/SET switch to set the speed to the
vehicle’s current speed.
When you push the RES/SET button to
reduce the speed, the braking system inter-
venes automatically if the engine brake
does not slow the vehicle down sufficiently
to reach the set speed. The device holds the
set speed uphill and downhill; however a
slight variation is entirely normal, particu -
larly on slight inclines.
The transmission could shift to a lower gear
when driving downhill, or when acceler -
ating. This is normal and necessary to main -
tain the set speed.
The system will disable while driving if the
brakes overheat.
To Resume

Once the system has been canceled but not
deactivated, to resume a previously set speed,
simply push the RES/SET switch upward and
remove your foot from the accelerator to recall it.

The system will be set to the last stored speed.
Setting The Distance Between Vehicles
The distance between your vehicle and the
vehicle ahead may be set to one bar (short),
two bars (medium), three bars (long), or four
bars (maximum). Distance Icons
The distances from the vehicle ahead are
proportional to speed.
The interval of time with relation to the vehicle
ahead remains constant and varies from one
second (for the short distance one-bar setting)
to two seconds (for the maximum distance
four-bar setting).
The set distance is shown on the display by a
dedicated icon.
The setting is four bars (maximum) the first
time the system is used. After the distance has
been modified by the driver, the new distance
will be stored even if the system is deactivated
and reactivated.
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.

TRAFFIC JAM ASSIST (TJA)
SYSTEM — IF EQUIPPED
The Traffic Jam Assist (TJA) system can be acti -
vated on all road types. The system uses a
camera to detect lane markings and keep the
vehicle in the center of the lane.
When the system is unable to detect lane
markings, it will still operate using surrounding
traffic. This can occur in congested traffic
scenarios, when the vehicles ahead or
surrounding obstruct the visibility of the lane
markings. When the speed is below 12 mph
(20 km/h), the system can use a lock-on
strategy that allows the vehicle to automati -
cally follow the vehicle ahead. The TJA system combines Adaptive Cruise
Control (ACC) functions with Lane Departure
Warning functions to maintain vehicle speed
and steering wheel behavior.

NOTE:

Do not use the TJA system while driving in
urban areas.
To Activate/Deactivate
To activate the system, push the button on the
left side of the steering wheel.

TRAFFIC SIGN RECOGNITION
(TSR) SYSTEM — IF EQUIPPED
The Traffic Sign Recognition (TSR) system
uses a camera mounted on the windshield to
detect recognizable road signs such as:
Speed limits
Signs indicating the end of the situations
indicated above
If the camera does not detect valid speed
limits, the radio system navigation system may
suggest unregulated speed limits.
The system always checks the traffic signs
indicating the current speed limit signs. The
system is able to recognize and display up to
two different road signs in the instrument
cluster display.
Depending on the unit of measurement (km or
mph) set through the “Unit of Measurement”
menu in the radio system, the TSR system will
automatically show the indication of the road
sign in the unit of measurements selected in
the instrument cluster display.
To Activate/Deactivate
The TSR System can be activated/deactivated
in the radio system in the “Driver Assistance”
menu. The system activation is signaled by
road signs shown on the instrument cluster
display.
NOTE:

By selecting “Blinking”, the driver can acti
-
vate a warning to display when the speed
exceeds the limit indicated by the TSR
System. The speed road sign on the instru -
ment cluster display will blink until the
vehicle speed drops below the displayed
limit.
Selecting “Offset” will set the speed at
which “Blinking” is activated up to a
maximum of 6 mph (10 km/h) above the
limit detected by the system.
If no speed limit signs are found, the system
will revert to the speed limit signs that are
stored in the NAV system.
Indications On The Display
The system status can always be viewed
through the instrument cluster display.
The instrument cluster display shows only the
speed limit indications and consists of the
following steps:
The new speed limit recognized by the
system, which is indicated by means of a
predetermined color. The road sign indi -
cating the end of the speed limit or a “Road
Sign Not Detected” message may appear in
this zone.
After a predetermined distance, the previ -
ously displayed road sign changes color to
inform the driver that the speed limit
provided may no longer be valid. 1 — Traffic Sign Recognized
WARNING!
To prevent serious injury or death:
Always remain alert and be ready to take
control of the vehicle in the event that the
TJA system disables.
Always keep your hands on the steering
wheel when the TJA system is activated.

Maintain a safe distance from other vehicles
and pay attention to traffic conditions.

CAUTION!
Functionality may be limited or the system
may not work if the sensor is obstructed.

The system may have limited operation or
not work at all in weather conditions such as
heavy rain, hail, thick fog, and low tempera
-
tures. Strong light contrasts can influence
the recognition capability of the sensor.

Acceptance/Rejection Of The Suggested
Speed
The system can be activated if the driver has
activated the following systems beforehand:
Adaptive Cruise Control (ACC)
Traffic Sign Recognition (TSR)
When these systems are active, a telltale will
display in the instrument cluster display indi -
cating the suggested speed provided by the
TSR system. The driver has the option to
accept or reject this using the RES/SET switch
on the steering wheel.
To accept the proposed speed and adjust the
speed set by ACC, move the RES/SET switch
up or down in the direction indicated in the tell -
tale.
To reject the proposed speed, move the RES/
SET switch up or down in the direction oppo -
site of the arrow in the telltale. The ACC system
will continue to regulate to the previously set
speed.
If the speed set by the ACC system is the same
as the speed detected by the TSR system, the
speed limit indicator on the instrument cluster
display will be highlighted with a green circle. 1 — Suggested Speed Higher Than
Current Speed
2 — Suggested Speed Lower Than Current Speed
1 —Road Sign Recognized
PARKSENSE FRONT/REAR
PARK ASSIST SYSTEM — IF
EQUIPPED
The ParkSense system provides visual and
audible indications of the distance between
the rear, and if equipped, the front fascia/
bumper and a detected obstacle when
backing up or moving forward (e.g. during a
parking maneuver). The vehicle brakes may be
automatically applied and released when
performing a reverse parking maneuver if the
system detects a possible collision with an
obstacle.
When the REVERSE gear is engaged and the
system is on, the front and rear sensors are
activated. If the vehicle moves from REVERSE
to a forward gear, the rear sensors are deacti -
vated, while the front sensors remain active
until the speed of 9 mph (15 km/h) is exceeded.

NOTE:

In certain operating conditions, the system
could start detecting an obstacle only after the
vehicle has moved slightly (a few inches).
