HOW DOES ALL-WHEEL DRIVE
WORK
All-wheel drive uses all four wheels to power
the vehicle. This increases traction, enabling
you to drive over terrain and road conditions
that a conventional two-wheel drive vehicle
cannot. The AWD system turns on when
needed and does not require input from you.
Note:
The AWD feature gives your vehicle
some limited off-road capabilities in which
driving surfaces are relatively level,
obstruction-free and otherwise similar to
normal on-road driving conditions. Operating
your vehicle in conditions other than those,
could subject the vehicle to excess stress
which might result in damage which is not
covered under your warranty. ALL-WHEEL DRIVE PRECAUTIONS WARNING: If you are driving in
slippery conditions that require tire chains
or cables, then it is critical that you drive
cautiously. Keep speeds down, allow for
longer stopping distances and avoid
aggressive steering to reduce the chances
of a loss of vehicle control which can lead
to serious injury or death. If the rear end
of your vehicle slides while cornering, steer
in the direction of the slide until you regain
control of your vehicle. WARNING:
Do not become
overconfident in the ability of all-wheel
drive vehicles. Although an all-wheel drive
vehicle may accelerate better than a
two-wheel drive vehicle in low traction
situations, it won't stop any faster than
two-wheel drive vehicles. Always drive at
a safe speed. ALL-WHEEL DRIVE LIMITATIONS
When using a mismatch spare tire on your
vehicle the all-wheel drive system can
become limited in function. To regain full
all-wheel drive capabilities have the standard
wheel replaced.
Different tire sizes between the front and
rear axles can cause system damage, or
disable the all-wheel drive system.
ALL-WHEEL DRIVE DRIVING HINTS
Emergency Maneuvers
In an unavoidable emergency where a
sudden sharp turn will be made, remember
to avoid over-driving your vehicle, for
example, turn the steering wheel only as
rapidly and as far as required to avoid the
emergency. Apply smooth pressure to the
accelerator pedal or brake pedal as needed.
214
2021 Nautilus (CD9) Canada/United States of America, enUSA, Edition date: 202011, First-Printing All-Wheel Drive
(If Equipped)

Avoid abrupt steering, acceleration and
braking changes. Abrupt changes could
increase the risk of vehicle roll over, loss of
vehicle control and personal injury. Use all
available road surfaces to bring your vehicle
under control.
In the event of an emergency stop, avoid
skidding and do not attempt any sharp
steering wheel movements.
Driving In Sand
When driving over sand, try to keep all four
wheels on the most solid area of the trail.
Shift to a lower gear and drive steadily
through the terrain. Apply the accelerator
slowly and avoid excessive wheel slip. Do
not drive your vehicle in deep sand for an
extended period of time. This will cause the
system to overheat. A message appears in
the information display. See All-Wheel Drive
– Information Messages (page 217).
Note: If your vehicle gets stuck in sand, it
may be rocked out by shifting between
forward and reverse gears, stopping
between shifts in a steady pattern. Press
lightly on the accelerator in each gear. Note:
Do not rock your vehicle if the engine
is not at normal operating temperature, as
damage to the transmission may occur.
Note: Do not rock your vehicle for more than
a minute, as damage to the transmission
and tires may occur or the engine may
overheat.
Driving Through Mud and Water
Mud
Be cautious of sudden changes in vehicle
speed or direction when you are driving in
mud. Even all-wheel drive vehicles can lose
traction in mud. If your vehicle does slide,
steer in the direction of the slide until you
regain control of your vehicle.
After driving through mud, clean off residue
stuck to rotating driveshafts and tires. Excess
mud stuck on tires and rotating driveshafts
can cause an imbalance that could damage
drive components. Note:
If your vehicle gets stuck in mud, it
may be rocked out by shifting between
forward and reverse gears, stopping
between shifts in a steady pattern. Press
lightly on the accelerator in each gear.
Note: Do not rock your vehicle if the engine
is not at normal operating temperature, as
damage to the transmission may occur.
Note: Do not rock your vehicle for more than
a minute, as damage to the transmission
and tires may occur or the engine may
overheat.
Water
If you must drive through deep water, drive
slowly. The water could limit traction or brake
capability. See Driving Through Water (page
305
).
When driving through water, determine the
depth and avoid water higher than the center
of the wheel.
215
2021 Nautilus (CD9) Canada/United States of America, enUSA, Edition date: 202011, First-Printing All-Wheel Drive
(If Equipped)

Once through water, always try the brakes.
Wet brakes will not stop your vehicle as
quickly as dry brakes. Apply light pressure
to the brake pedal while slowly moving the
vehicle to dry the brakes.
Note:
Driving through deep water could
cause damage to the transmission. If the
front or rear axle is submerged in water, the
axle lubricant and power transfer unit
lubricant should be checked and changed
if necessary.
Driving on Hilly or Sloping Terrain
Although natural obstacles could make it
necessary to travel diagonally up or down a
hill or steep incline, you should try to drive
straight up or straight down.
Note: Avoid turning on steep slopes or hills.
A danger lies in losing traction, slipping
sideways and possible vehicle roll over.
Whenever driving on a hill, determine
beforehand the route you can use. Do not
drive over the crest of a hill without seeing
what conditions are on the other side. Do
not drive in reverse over a hill without the
aid of an observer. Apply just enough power to the wheels to
climb the hill. Too much power will cause the
tires to slip, spin or lose traction, and you
could lose control of your vehicle.
When descending a steep hill, do not
descend the hill in neutral. Avoid sudden
hard braking to keep the front wheels rolling
and to maintain your vehicle's steering.
Note:
If your vehicle has anti-lock brakes,
apply the brakes steadily. Do not pump the
brakes.
Note: If your vehicle gets stuck driving on
hilly or sloping terrain, it may be rocked out
by shifting between forward and reverse
gears, stopping between shifts in a steady
pattern. Press lightly on the accelerator in
each gear.
Note: Do not rock your vehicle if the engine
is not at normal operating temperature, as
damage to the transmission may occur.
Note: Do not rock your vehicle for more than
a minute, as damage to the transmission
and tires may occur or the engine may
overheat. Driving on Snow and Ice WARNING: If you are driving in
slippery conditions that require tire chains
or cables, then it is critical that you drive
cautiously. Keep speeds down, allow for
longer stopping distances and avoid
aggressive steering to reduce the chances
of a loss of vehicle control which can lead
to serious injury or death. If the rear end
of your vehicle slides while cornering, steer
in the direction of the slide until you regain
control of your vehicle.
Avoid sudden applications of power and
quick changes of direction on snow and ice.
Apply the accelerator slowly and steadily
when starting from a full stop.
Avoid sudden braking. Although an all-wheel
drive vehicle accelerates better than a
two-wheel drive vehicle in snow and ice, it
cannot stop any faster as braking occurs at
all four wheels. Do not become
overconfident of the road conditions.

Make sure that you allow sufficient distance
between your vehicle and other vehicles for
stopping. On ice and snow, you should drive
more slowly than usual. In emergency
stopping situations, steadily apply the brake.
Your vehicle has a four wheel anti-lock brake
system, do not pump the brake pedal. See
Anti-Lock Braking System Limitations (page
218
).
Note: If your vehicle gets stuck driving on
snow and ice, it may be rocked out by
shifting between forward and reverse gears,
stopping between shifts in a steady pattern.
Press lightly on the accelerator in each gear. Note:
Do not rock your vehicle if the engine
is not at normal operating temperature, as
damage to the transmission may occur.
Note: Do not rock your vehicle for more than

Check Brake System
Brakes – Frequently Asked Questions
Is brake dust on the wheels normal? Brake dust could accumulate on the
wheels, even under normal driving
conditions. Some dust is inevitable as
the brakes wear and does not contribute
to brake noise.
See Cleaning Wheels
(page 356). Will wet driving conditions effect my
braking abilities?
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.
Is brake noise considered normal? Occasional brake noise is normal. If a
metal-to-metal, continuous grinding or
continuous squeal sound is present, the
brake linings may be worn-out and an
authorized dealer should check them.
If the vehicle has continuous vibration
or shudder in the steering wheel while
braking, an authorized dealer should
check your vehicle.
When should you replace the brake fluid? Brake fluid absorbs water over time
which degrades the effectiveness of the
brake fluid. Change the brake fluid at
the specified intervals to prevent
degraded braking performance.

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

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.
