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.
305
2021 Nautilus (CD9) Canada/United States of America, enUSA, Edition date: 202011, First-Printing Driving Hints

When driving through standing water, drive
very slowly and do not stop your vehicle.
Your brake performance and traction may
be limited. After driving through water and
as soon as it is safe to do so:
•
Lightly press the brake pedal to dry the
brakes and to check that they work.
• Check that the horn works.
• Check that the exterior lights work.
• Turn the steering wheel to check that the
steering power assist works. DRIVING ECONOMICALLY
The following helps to improve fuel
consumption:
•
Drive smoothly, accelerate gently and
anticipate the road ahead to avoid heavy
braking.
• Regularly check your tire pressures and
make sure that they are inflated to the
correct pressure.
• Follow the recommended maintenance
schedule and carry out the
recommended checks.
• Plan your journey and check the traffic
before you set off. It is more efficient to
combine errands into a single trip
whenever possible.
• Avoid idling the engine in cold weather
or for extended periods. Start the engine
only when you are ready to set off.
• Do not carry unnecessary weight in your
vehicle as extra weight wastes fuel. •
Do not add unnecessary accessories to
the exterior of your vehicle, for example
running boards. If you use a roof rack,
remember to fold it down or remove it
when not in use.
• Do not shift into neutral when you are
braking or when your vehicle is slowing
down.
• Shut all windows when driving at high
speeds.
• Switch off all electric systems when not
in use, for example air conditioning. Make
sure that you unplug any accessories
from the auxiliary power points when not
in use.
FLOOR MATS WARNING: Use a floor mat designed
to fit the footwell of your vehicle that does
not obstruct the pedal area. Failure to
follow this instruction could result in the
loss of control of your vehicle, personal
injury or death.

Fail-Safe Cooling
Fail-safe cooling allows you to temporarily
drive your vehicle before any incremental
component damage occurs. The fail-safe
distance depends on ambient temperature,
vehicle load and terrain.
How Fail-Safe Cooling Works
If the engine begins to overheat,
the coolant temperature gauge
moves toward the red zone:
A warning lamp illuminates and a
message may appear in the
information display.
If the engine reaches a preset
over-temperature condition, the engine
automatically switches to alternating cylinder
operation. Each disabled cylinder acts as an
air pump and cools the engine.
When this occurs, your vehicle still operates,
however:
• Engine power is limited.
• The air conditioning system turns off. Continued operation increases the engine
temperature, causing the engine to
completely shut down. Your steering and
braking effort increases in this situation.
When the engine temperature cools, you can
re-start the engine. Have your vehicle
checked as soon as possible to minimize
engine damage.
When Fail-Safe Mode Is Activated
WARNING: Fail-safe mode is for use
during emergencies only. Operate your
vehicle in fail-safe mode only as long as
necessary to bring your vehicle to rest in
a safe location and seek immediate repairs.
When in fail-safe mode, your vehicle will
have limited power, will not be able to
maintain high-speed operation, and may
completely shut down without warning,
potentially losing engine power, power
steering assist, and power brake assist,
which may increase the possibility of a
crash resulting in serious injury. WARNING: Do not remove the
coolant reservoir cap when the engine is
on or the cooling system is hot. Wait 10
minutes for the cooling system to cool
down. Cover the coolant reservoir cap with
a thick cloth to prevent the possibility of
scalding and slowly remove the cap.
Failure to follow this instruction could result
in personal injury.
Your vehicle has limited engine power when
in the fail-safe mode, drive your vehicle with
caution. Your vehicle does not maintain
high-speed operation and the engine could
operate poorly.
Remember that the engine is capable of
automatically shutting down to prevent
engine damage. In this situation:
1. Pull off the road as soon as safely possible and switch the engine off.
2. If you are a member of a roadside assistance program, we recommend that
you contact your roadside assistance
service provider.
