WHAT IS HILL START ASSIST
Hill Start Assist makes it easier for you to pull
away when your vehicle is on a slope without
using the parking brake.
HOW DOES HILL START ASSIST
WORK
When the system activates, your vehicle
remains stationary for a few seconds after
you release the brake pedal. This gives you
time to move your foot from the brake pedal
to the accelerator pedal. The brakes release
when the engine has developed sufficient
torque to prevent your vehicle from rolling
down the slope.
HILL START ASSIST PRECAUTIONS
WARNING: The system does not
replace the parking brake. When you leave
your vehicle, always apply the parking
brake. WARNING: You must remain in your
vehicle when the system turns on. At all
times, you are responsible for controlling
your vehicle, supervising the system and
intervening, if required. Failure to take care
may result in the loss of control of your
vehicle, serious personal injury or death. WARNING:
The system turns off if
there is a malfunction or if you excessively
rev the engine.

HOW DOES TRACTION CONTROL
WORK
If your vehicle begins to slide, the system
applies the brakes to individual wheels and,
when needed, reduces power at the same
time. If the wheels spin when accelerating
on slippery or loose surfaces, the system
reduces power in order to increase traction.
SWITCHING TRACTION CONTROL
ON AND OFF
WARNING: The stability and traction
control light illuminates steadily if the
system detects a failure. Make sure you
did not manually disable the traction
control system using the information
display controls or the switch. If the stability
control and traction control light is still illuminating steadily, have the system
serviced by an authorized dealer
immediately. Operating your vehicle with
the traction control disabled could lead to
an increased risk of loss of vehicle control,
vehicle rollover, personal injury and death.
When you switch the system off or on, a
message appears in the information display
showing system status.
You can switch the system off with the
traction control switch.
Using a Switch
Use the traction control switch on the
instrument panel to switch the system off or
on.

HOW DOES STABILITY CONTROL
WORK
WARNING: Vehicle modifications
involving braking system, aftermarket roof
racks, suspension, steering system, tire
construction and wheel and tire size may
change the handling characteristics of your
vehicle and may adversely affect the
performance of the electronic stability
control system. In addition, installing any
stereo loudspeakers may interfere with
and adversely affect the electronic stability
control system. Install any aftermarket
stereo loudspeaker as far as possible from
the front center console, the tunnel, and
the front seats in order to minimize the risk
of interfering with the electronic stability
control sensors. Reducing the
effectiveness of the electronic stability
control system could lead to an increased
risk of loss of vehicle control, vehicle
rollover, personal injury and death. WARNING:
Remember that even
advanced technology cannot defy the laws
of physics. It's always possible to lose
control of a vehicle due to inappropriate
driver input for the conditions. Aggressive
driving on any road condition can cause
you to lose control of your vehicle
increasing the risk of personal injury or
property damage. Activation of the
electronic stability control system is an
indication that at least some of the tires
have exceeded their ability to grip the
road; this could reduce the operator's
ability to control the vehicle potentially
resulting in a loss of vehicle control, vehicle
rollover, personal injury and death. If your
electronic stability control system activates,
SLOW DOWN.
If a driving condition activates either the
stability control or the traction control system
you may experience the following conditions: •
The stability and traction control light
flashes.
• Your vehicle slows down.
• Reduced engine power.
The stability control system has several
features built into it to help you maintain
control of your vehicle:
Electronic Stability Control
Electronic stability control enhances your
vehicle ’s ability to prevent skids or lateral
slides by applying brakes to one or more of
the wheels individually and, if necessary,
reducing engine power.
Roll Stability Control
Roll stability control enhances your vehicle ’s
ability to prevent rollovers by detecting your
vehicle ’s roll motion and the rate at which it
changes by applying the brakes to one or
more wheels individually.
229
2021 Nautilus (CD9) Canada/United States of America, enUSA, Edition date: 202011, First-Printing Stability Control

Curve Control
Curve control enhances your vehicle
’s ability
to follow the road when cornering severely
or avoiding objects in the roadway. Curve
control operates by reducing engine power
and, if necessary, applying brakes to one or
more of the wheels individually.
Traction Control
Traction control enhances your vehicle ’s
ability to maintain traction of the wheels by
detecting and controlling wheel spin. See
How Does Traction Control Work (page 228). Vehicle without stability control

B SWITCHING STABILITY CONTROL
ON AND OFF
The system turns on each time you switch
the ignition on.
You can switch the electronic stability control
system off by pressing and holding the ESC
off button for over 15 seconds, or you can
press the button again to switch the system
on.
Shifting the transmission into
reverse (R) disables the system.
You can switch the traction control system
off or on independently.
See Switching
Traction Control On and Off (page 228).

switch the power on, or remains
on, this indicates a malfunction.
Have your vehicle checked by an authorized
dealer as soon as possible.

PARKING AID PRECAUTIONS
WARNING: To help avoid personal
injury, always use caution when in reverse
(R) and when using the sensing system. WARNING:
The system may not
detect objects with surfaces that absorb
reflection. Always drive with due care and
attention. Failure to take care may result
in a crash. WARNING:
Traffic control systems,
fluorescent lamps, inclement weather, air
brakes, external motors and fans may
affect the correct operation of the sensing
system. This may cause reduced
performance or false alerts. WARNING:
The system may not
detect small or moving objects, particularly
those close to the ground. WARNING:
The parking aid system
can only assist you to detect objects when
your vehicle is moving at parking speeds.
To help avoid personal injury you must
take care when using the parking aid
system. WARNING:
The system may not
function if the sensor is blocked. WARNING:
In cold and severe
weather conditions the system may not
function. Rain, snow and spray can all limit
sensor performance. WARNING:
If damage occurs in the
immediate area surrounding the sensor,
have your vehicle checked as soon as
possible.
Note: If your vehicle sustains damage
leaving the sensors misaligned, this will
cause inaccurate measurements or false
alerts. When you connect a trailer to your vehicle,
the rear parking aid detects the trailer and
provides an alert. Disable the parking aid
when you connect a trailer to prevent the
alert.
Note:
Certain add-on devices installed
around the bumper or fascia may create
false alerts, for example, large trailer hitches,
bike or surfboard racks, license plate
brackets, bumper covers or any other device
that could block the normal detection zone
of the parking aid system. Aftermarket spare
tires or spare tire covers mounted to the rear
tailgate could cause false alerts from the
park aid system. Remove the add-on device
to prevent false alerts.
Note: Keep the sensors free from snow, ice
and large accumulations of dirt. If the
sensors are covered, the system's accuracy
can be affected.
Do not clean the sensors with sharp objects.
Note: When using a programmed MyKey
you cannot switch this off.
See MyKey™
(page 84).
