vehicle can travel on the fuel remaining in
the tank. Changes in driving pattern can
cause the value to not only decrease but also
increase or stay constant for periods of time.
WHAT IS THE ENGINE COOLANT
TEMPERATURE GAUGE
Indicates the engine coolant temperature.
WHAT IS THE ENGINE OIL
PRESSURE GAUGE
Indicates the engine oil pressure.
Note:
This is a configurable gauge.
WHAT IS THE TRANSMISSION
FLUID TEMPERATURE GAUGE
Indicates the transmission fluid temperature. Special operating conditions can cause
higher than normal operating temperatures.
See Special Operating Conditions
Scheduled Maintenance (page 467).
Note: This is a configurable gauge.
WHAT IS THE 12V BATTERY
GAUGE
Indicates the power of the 12-volt battery.
WHAT ARE THE INSTRUMENT
CLUSTER WARNING LAMPS
Warning lamps alert you to a vehicle
condition that could become serious. Some
lamps illuminate when you start your vehicle
to make sure they work. If any lamps remain
on after starting your vehicle, refer to the
respective system warning lamp for further
information. INSTRUMENT CLUSTER WARNING
LAMPS
Anti-Lock Brake System If it illuminates when you are
driving, this indicates that the
system requires service. Your
vehicle continues to have normal braking
without the anti-lock brake system function.
Have your vehicle checked as soon as
possible.
Battery It illuminates when you switch the
ignition on.
If it illuminates when the engine is
running, this indicates your vehicle requires
service. Have your vehicle checked as soon
as possible.

AUTOMATIC TRANSMISSION
PRECAUTIONS
WARNING: Always fully apply the
parking brake and make sure you shift into
park (P). Failure to follow this instruction
could result in personal injury or death. WARNING:
Do not apply the brake
pedal and accelerator pedal
simultaneously. Applying both pedals
simultaneously for more than a few
seconds will limit engine performance,
which may result in difficulty maintaining
speed in traffic and could lead to serious
injury. WARNING:
When your vehicle is
stationary, keep the brake pedal fully
pressed when shifting gears. Failure to
follow this instruction could result in
personal injury, death or property damage. Note:
Do not use supplemental transmission
fluid additives, treatments, or cleaning
agents. Failure to follow this instruction could
result in vehicle damage not covered by the
vehicle warranty.
AUTOMATIC TRANSMISSION
POSITIONS
Park (P) WARNING:
Move the transmission
selector lever to park (P) only when your
vehicle is stationary.
This position locks the driveline. Come to a
complete stop before putting your vehicle
into and out of park (P).
The electric parking brake could apply when
you shift to park (P) without the brake pedal
fully pressed. The electric parking brake
applies when you shift to park (P) on large
slopes. The electric parking brake releases
with the drive away release function.
See
Electric Parking Brake (page 221). Note:
A warning tone sounds if you open the
driver door and you have not shifted the
transmission selector to park (P).
Reverse (R) WARNING:
Move the transmission
selector lever to reverse (R) only when your
vehicle is stationary and the engine is at
idle speed.
This position allows your vehicle to move
backward. Come to a complete stop before
shifting into and out of reverse (R).
Neutral (N) WARNING: In neutral (N) your vehicle
has the ability to roll freely. If you intend to
leave your vehicle, make sure you apply
the parking brake.
This position allows your vehicle to roll free.
Hold the brake pedal down when in this
position.

2021 Nautilus (CD9) Canada/United States of America, enUSA, Edition date: 202011, First-Printing Automatic Transmission

BRAKE PRECAUTIONS
WARNING: Driving your vehicle with
the warning lamp on is dangerous. A
significant decrease in braking
performance may occur. It may take you
longer to stop your vehicle. Have your
vehicle checked as soon as possible.
Driving extended distances with the
parking brake engaged can cause brake
failure and the risk of personal injury.
Wet brakes result in reduced braking
efficiency. Gently press the brake pedal a
few times when driving from a car wash or
standing water to dry the brakes. ANTI-LOCK BRAKING SYSTEM
Anti-Lock Braking System Limitations
The anti-lock braking system does not
eliminate the risk of crash when:
•
You drive too closely to the vehicle in
front of you.
• Your vehicle is hydroplaning.
• You take corners too fast.
• The road surface is poor.
Note: If the system activates, the brake
pedal could pulse and could travel further.
Maintain pressure on the brake pedal.
BRAKE OVER ACCELERATOR
In the event the accelerator pedal becomes
stuck or entrapped, apply steady and firm
pressure to the brake pedal to slow the
vehicle and reduce engine power. If you
experience this condition, apply the brakes
and bring your vehicle to a safe stop. Move the transmission to park (P), switch the
engine off and apply the parking brake.
Inspect the accelerator pedal for any
interference. If none are found and the
condition persists, have your vehicle towed
to the nearest authorized dealer.
LOCATING THE BRAKE FLUID
RESERVOIR
See
Under Hood Overview (page 334).
CHECKING THE BRAKE FLUID WARNING: Do not use any fluid other
than the recommended brake fluid as this
will reduce brake efficiency. Use of
incorrect fluid could result in the loss of
vehicle control, serious personal injury or
death.

WHAT IS DRIVE MODE CONTROL
Your vehicle has various drive modes that
you can select for different driving
conditions. Depending on the drive mode
that you select, the system adjusts various
vehicle settings.
HOW DOES DRIVE MODE
CONTROL WORK
Drive mode control adjusts your vehicle
configuration for each mode you select.
Changing the drive mode changes the
functionality of the steering system to adjust
the steering effort and feel.
Active noise control utilizes your vehicle
electronics to enhance the acoustic
experience.
The stability and traction control assist your
vehicle control in adverse conditions or
high-performance driving.
Throttle control enhances the powertrain
response, transmission controls become
optimized with shift schedules, and
four-wheel drive settings are optimized and
tuned to each mode.
Note:
The system has diagnostic checks that
continuously monitor the system for proper
operation. If a mode is unavailable due to a
system fault, the mode defaults to normal.
SELECTING A DRIVE MODE
You can configure which of the drive control
modes are active when your vehicle is in
drive (D) or in sport (S). The configuration
remains active until modified from the main
menu on the instrument cluster display. See
Instrument Cluster Display Main Menu
(page 144).
Note: Not all settings may be available.
Note: Drive mode changes may not be
available when the ignition is off. DRIVE MODES
Comfort
Provides a more relaxed driving experience,
maximizing comfort. Your steering effort
decreases and the suspension movement is
more fluid. Comfort mode is ideal when you
desire enhanced traveling comfort.
Normal
Delivers a balanced combination of a
comfortable, controlled ride and confident
handling. This mode provides an engaging
driving experience and a direct connection
to the road without sacrificing any of the
composure demanded from a luxury vehicle.
Sport
Provides a sportier driving experience. The
suspension stiffens, with an emphasis on
handling and control. The engine responds
more directly to your inputs and takes on a
more powerful tone. This mode is ideal for
use during more spirited driving.
