ELECTRIC POWER STEERING
ELECTRIC POWER STEERING
PRECAUTIONS
WARNING: The electric power
steering system has diagnostic checks that
continuously monitor the system. If a fault
is detected, a message displays in the
information display. Stop your vehicle as
soon as it is safe to do so. Switch the
vehicle off. After at least 10 seconds, switch
the vehicle on and watch the information
display for a steering system warning
message. If a steering system warning
message returns, have the system checked
as soon as possible. WARNING:
If the system detects an
error, you may not feel a difference in the
steering, however a serious condition may
exist. Have your vehicle checked as soon
as possible. Failure to do so may result in
loss of steering control. Adapt your speed and driving behavior
according to reduced steering assist.
Extreme continuous steering may increase
the effort to steer. This occurs to prevent
internal overheating and damage to the
steering system. If this occurs, you will not
lose the ability to steer your vehicle manually
nor will it cause damage to the system.
Normal steering and driving allows the
system to cool down and steering assist
returns to normal.
Note:
There is no fluid reservoir to check or
fill.
ELECTRIC POWER STEERING
ADAPTIVE STEERING
(If Equipped)
The adaptive steering system changes the
steering ratio with changes to vehicle speed,
optimizing the steering response in all
conditions. The system also changes when
you switch on the transmission tow/haul
feature. When you select the tow/haul button,
the adaptive steering system reduces vehicle
sensitivity to steering inputs at higher vehicle
speeds, while maintaining the ease of
parking and maneuverability at low speeds. Note:
The adaptive steering system
continuously monitors for faults. If the system
detects a fault, a message appears in the
information display. If a red warning
message displays, stop your vehicle as soon
as it is safe to do so. The message could
clear if the fault is no longer present. If an
adaptive steering system warning message
appears each time you start your vehicle,
have the system checked as soon as
possible.
Note: The system has a locking device. It
remains mechanically locked at a fixed
steering ratio with the lock engaged. You
may notice a click when you turn your
vehicle on or off.
Note: If your vehicle loses electrical power
or detects a fault when you are driving, the
system shuts down and you retain a normal
steering function with a fixed steering ratio.
During this time, it is possible that the
steering wheel could not be straight when
the vehicle is driving straight ahead. In
addition, you could notice that the steering
wheel angle required to steer your vehicle
could be different.

Note:
During parking maneuvers, the
adaptive steering system balances the driver
workload for various steering wheel inputs
and vehicle loading conditions. Under
extreme operating conditions the system
locking device could engage. This strategy
prevents overheating and permanent
damage to the adaptive steering system.
Typical steering and driving maneuvers
allow the system to cool and return to normal
operation. Adaptive Learning
Adaptive learning helps correct road
irregularities and improves overall handling
and steering. It communicates with the brake
system to help operate advanced stability
control and crash avoidance systems.
Additionally, whenever you disconnect the
battery or install a new battery, you must
drive your vehicle a short distance before
the system relearns the strategy and
reactivates all systems.STEERING – TROUBLESHOOTING
STEERING – WARNING INDICATORS The adaptive steering system
indicator illuminates if the system
detects a fault during the
continuous diagnostic checks.
Note: If a red warning message displays,
stop your vehicle as soon as it is safe to do
so.

FRONT PARKING AID AUDIBLE
WARNINGS
A warning tone sounds when there is an
object within 28 in (70 cm) from the front
bumper. As your vehicle moves closer to an
object, the rate of the tone increases.
The warning tone continuously sounds when
an object is
12 in (30 cm) or less from the
front bumper.
Note: If the detected object is
12 in (30 cm)
or less from your vehicle, visual indication
remains on.
SIDE PARKING AID
WHAT IS THE SIDE PARKING AID
The front and rear outermost parking aid
sensors map objects that are near to the
sides of your vehicle.
SIDE PARKING AID LIMITATIONS
The sensor coverage is up to
24 in (60 cm)
from the sides of your vehicle. The side parking aid may not function if:
•
Your vehicle remains stationary for over
two minutes.
• The anti-lock brake system activates.
• The traction control system activates.
• Your vehicle is in park (P).
• The steering wheel angle information is
not available. You must drive at least
492 ft (150 m) above 19 mph (30 km/h) to
reset the steering wheel angle
information.
Note: If you switch traction control off, the
side sensing system also turns off.
To reinitialize the system, drive the length of
your vehicle.
The side parking aid does not detect an
object that is moving toward the side of your
vehicle, for example another vehicle moving
at a low speed, if it does not pass a front or
rear parking aid sensor. If the transmission is in reverse (R), the side
sensing system provides audible warnings.
When your vehicle is moving slowly,
obstacles are detected within
24 in (60 cm)
and are inside the driving path of your
vehicle. If your vehicle remains stationary for
a few seconds, the audible warning turns off.
Visual indication is always present in reverse
(R).
If your vehicle is in neutral (N), the side
sensing system provides visual indication
only when your vehicle is moving slowly and
there is a front or rear parking aid obstacle
detected, and the side obstacle is within
24 in (60 cm)
from the side of your vehicle.
If your vehicle remains stationary for a few
seconds, the visual indication turns off.
If the transmission is in drive (D) or any other
forward gear, the side sensing system
provides audible and visual warnings. When
your vehicle is moving slowly, obstacles are
detected within
24 in (60 cm) and are inside
the driving path of your vehicle. If your
vehicle remains stationary for a few seconds,
the visual indication and audible warning
turns off.

Detection Issues Can Occur:
When driving on a different line
than the vehicle in front.
A B With vehicles that edge into your
lane. The system can only detect
these vehicles once they move
fully into your lane.
There may be issues with the
detection of vehicles in front when
driving into and coming out of a
bend or curve in the road.
C
In these cases, the system may brake late or
unexpectedly.
If something hits the front end of your vehicle
or damage occurs, the radar-sensing zone
may change. This could cause missed or
false vehicle detection.
Optimal system performance requires a clear
view of the road by the windshield camera.
Optimal performance may not occur if:
• The camera is blocked.
• There is poor visibility or lighting
conditions.
• There are bad weather conditions. SWITCHING ADAPTIVE CRUISE
CONTROL ON AND OFF
The cruise controls are on the steering
wheel. See Visual Search (page 29).
Switching Adaptive Cruise Control On Press the button to activate the
system. When the system
activates, the set speed is equal to
whichever is greater, the current vehicle
speed, or 15 mph when in imperial units or
20 km/h when in metric units. If the speed is
too low, or other conditions are not correct
for adaptive cruise control activation, the
system enters standby mode. When you are
below 15 mph when in imperial units or 20
km/h when in metric units, adaptive cruise
control does not activate unless you are
following another vehicle.
The indicator, current gap setting and set
speed appear in the instrument cluster
display.

LANE CENTERING
HOW DOES LANE CENTERING WORK
Adaptive cruise control with lane centering
uses radar and camera sensors to help keep
your vehicle in the middle of the lane by
applying continuous assistance steering
torque input toward the lane center on
highways. Note:
The adaptive cruise control gap setting
operates normally.
If you drive off-center within the lane, the
system sets and maintains that preferred lane
position. The system provides continuous
assistance steering torque input toward the
preferred position.
Note: The system can only set preferred lane
positions within the lane.
Note: If the system cancels, the preferred
position erases. On the next activation, the
system provides continuous assistance
steering torque input toward the lane center.
LANE CENTERING PRECAUTIONS WARNING:
Do not use the system
when towing a trailer. Failure to follow this
instruction could result in the loss of
control of your vehicle, personal injury or
death. WARNING: Do not use the system if
any changes or modifications to the
steering wheel have been made. Any
changes or modifications to the steering
wheel could affect the functionality or
performance of the system. Failure to
follow this instruction could result in the
loss of control of your vehicle, personal
injury or death.
Adaptive cruise control precautions apply to
lane centering unless stated otherwise or
contradicted by a lane centering precaution.
