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.

(If Equipped)

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
a minute, as damage to the transmission
and tires may occur or the engine may
overheat.

•
Check your hitch, electrical connections
and trailer wheel lug nuts thoroughly after
you have traveled 50 mi (80 km).
• When stopped in congested or heavy
traffic during hot weather, place the
transmission in park (P) to aid engine and
transmission cooling and to help A/C
performance.
• Turn off the speed control with heavy
loads or in hilly terrain. The speed control
may turn off when you are towing on
long, steep slopes.
• Shift to a lower gear when driving down
a long or steep hill. Do not continuously
apply the brakes, as they may overheat
and become less effective.
• If your transmission has Grade Assist or
Tow/Haul, use this feature when towing.
This provides engine braking and helps
eliminate excessive transmission shifting
for optimum fuel economy and
transmission cooling. •
If your vehicle has AdvanceTrac with roll
stability control, this system may turn on
during typical cornering maneuvers with
a heavily loaded trailer. This is normal.
Turning the corner at a slower speed
when towing may reduce this tendency.
• If you are frequently towing a trailer in
hot weather, hilly conditions, at the gross
combined weight rating or any
combination of these factors, consider
refilling your rear axle with synthetic gear
lubricant if the axle is not already filled
with it.
• Allow more distance for stopping with a
trailer attached. Anticipate stops and
gradually brake.
• Avoid parking on a slope. However, if
you must park on a slope, turn the
steering wheel to point your vehicle tires
away from traffic flow, set the parking
brake, place the transmission in park (P)
and place wheel chocks in front and back
of the trailer wheels.
Note: Chocks are not included with your
vehicle. LAUNCHING OR RETRIEVING A
BOAT OR PERSONAL
WATERCRAFT
When backing down a ramp during boat
launching or retrieval:
•
Do not allow the static water level to rise
above the bottom edge of the rear
bumper.
• Do not allow waves to break higher than
6 in (15 cm)
above the bottom edge of
the rear bumper.
Exceeding
6 in (15 cm) could allow water to
enter vehicle components, causing internal
damage to the components and affecting
driveability, emissions and reliability.
Note: Replace the rear axle lubricant
anytime the rear axle has been submerged
in water.
Note: Disconnect the trailer wiring connector
before backing the trailer into the water.
Note: Reconnect the trailer wiring connector
after removing the trailer from the water.

REDUCED ENGINE PERFORMANCE
WARNING: If you continue to drive
your vehicle when the engine is
overheating, the engine could stop without
warning. Failure to follow this instruction
could result in the loss of control of your
vehicle.
If the engine coolant temperature gauge
needle moves to the upper limit position, the
engine is overheating.
See What Is the
Engine Coolant Temperature Gauge (page
139).
You must only drive your vehicle for a short
distance if the engine overheats. The
distance you can travel depends on ambient
temperature, vehicle load and terrain. The
engine continues to operate with limited
power for a short period of time.
If the engine temperature continues to rise,
the fuel supply to the engine reduces. The
air conditioning switches off and the engine
cooling fan operates continually. 1. Gradually reduce your speed and stop
your vehicle as soon as it is safe to do
so.
2. Immediately switch the engine off to prevent severe engine damage.
3. Wait for the engine to cool down.
4. Check the coolant level.
See Checking
the Coolant (page 340).
5. Have your vehicle checked as soon as possible.
COLD WEATHER PRECAUTIONS
The functional operation of some
components and systems can be affected at
temperatures below approximately
-13°F
(-25°C).
BREAKING-IN
You need to break in new tires for
approximately
300 mi (480 km). During this
time, your vehicle may exhibit some unusual
driving characteristics. DRIVING THROUGH WATER WARNING:
Do not drive through
flowing or deep water as you may lose
control of your vehicle.
Note: Driving through standing water can
cause vehicle damage.
Note: Engine damage can occur if water
enters the air filter.
Before driving through standing water, check
the depth. Never drive through water that is
higher than the bottom of the front rocker
area of your vehicle.
