Noise Emissions Warranty, Prohibited
Tampering Acts and Maintenance
On January 1, 1978, Federal regulation
became effective governing the noise
emission on trucks over 10,000 lb (4,536 kg)
Gross Vehicle Weight Rating (GVWR). The
preceding statements concerning prohibited
tampering acts and maintenance, and the
noise warranty found in the Warranty Guide,
are applicable to complete chassis cabs over
10,000 lb (4,536 kg)
GVWR. CATALYTIC CONVERTER WARNING: Do not park, idle or drive
your vehicle on dry grass or other dry
ground cover. The emission system heats
up the engine compartment and exhaust
system, creating the risk of fire. WARNING:
The normal operating
temperature of the exhaust system is very
high. Never work around or attempt to
repair any part of the exhaust system until
it has cooled. Use special care when
working around the catalytic converter.
The catalytic converter heats up to a very
high temperature after only a short period
of engine operation and stays hot after the
engine is switched off. WARNING:
Exhaust leaks may result
in entry of harmful and potentially lethal
fumes into the passenger compartment. If
you smell exhaust fumes inside your
vehicle, have your vehicle inspected
immediately. Do not drive if you smell
exhaust fumes. Your vehicle has various emission control
components and a catalytic converter that
enables it to comply with applicable exhaust
emission standards.
To make sure that the catalytic converter and
other emission control components continue
to work properly:
•
Do not crank the engine for more than
10 seconds at a time.
• Do not run the engine with a spark plug
lead disconnected.
• Do not push-start or tow-start your
vehicle. Use booster cables.
See Jump
Starting the Vehicle (page 290).
• Use only the specified fuel listed.
• Do not switch the ignition off when your
vehicle is moving.
• Avoid running out of fuel.
• Have the items listed in scheduled
maintenance information performed
according to the specified schedule.
Note: Resulting component damage may
not be covered by the vehicle Warranty.

USING ALL-WHEEL DRIVE
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 under other than those
conditions could subject the vehicle to
excessive stress that might result in damage
that your vehicle warranty does not cover.
Note: A warning message appears in the
information display when an AWD system
fault is present. See Information Messages
(page 122). An AWD system fault causes the
AWD system to default to front-wheel drive
only mode. When this warning message
displays, have your vehicle serviced at an
authorized dealer Note:
A warning message appears in the
information display if the AWD system has
overheated. See Information Messages
(page 122). This condition may occur if you
operate the vehicle in extreme conditions
with excessive wheel slip, such as deep
sand. To resume normal AWD function as
soon as possible, stop the vehicle in a safe
location and stop the engine for at least 10
minutes. After you restart the engine and the
AWD system adequately cools, the warning
message turns off and normal AWD function
returns.
Do not use a spare tire of a different size
other than the tire provided. If the mini-spare
tire is installed, the AWD system may disable
automatically and enter front-wheel drive
only mode to protect driveline components.
A warning in the information display appears,
indicating that the system is in front-wheel
drive only mode. See Information Messages
(page
122). If there is a warning message in
the information display from using the spare
tire, this indicator should turn off after
reinstalling the repaired or replaced normal
road tire and cycling the ignition off and on.
We recommend that you reinstall the repaired or replaced road tire as soon as
possible. Major dissimilar tire sizes between
the front and rear axles could cause the AWD
system to stop functioning and default to
front-wheel drive or damage the AWD
system.
Driving in Special Conditions with All-
Wheel Drive (AWD)
AWD vehicles are ready to drive on sand,
snow, mud and rough roads and have
operating characteristics that are somewhat
different from conventional vehicles, both on
and off the highway.
Under severe operating conditions, the A/C
may cycle on and off to protect overheating
of the engine.
Basic operating principles in special
conditions
•
Drive slower in strong crosswinds which
can affect the normal steering
characteristics of your vehicle.
• Be extremely careful when driving on
pavement made slippery by loose sand,
water, gravel, snow or ice.

Nautilus (CD9) Canada/United States of America, enUSA, Edition date: 201907, First-Printing All-Wheel Drive
(If Equipped)

Your vehicle has anti-lock brakes, therefore
apply the brakes steadily. Do not “pump
” the
brakes.
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.
Note: Excessive tire slippage can cause
driveline damage.
AWD vehicles have advantages over 2WD
vehicles in snow and ice but can skid like
any other vehicle. Should you start to slide when driving on
snowy or icy roads, turn the steering wheel
in the direction of the slide until you regain
control.
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 as well. Although an
AWD vehicle may accelerate better than a
two-wheel drive vehicle in snow and ice, it
does not stop any faster, because as in other
vehicles, braking occurs at all four wheels.
Do not become overconfident as to road
conditions.
Make sure you allow sufficient distance
between you and other vehicles for stopping.
Drive slower than usual and consider using
one of the lower gears. In emergency
stopping situations, apply the brake steadily.
Since your vehicle comes with a four wheel
(ABS), do not “pump
” the brakes. See Hints
on Driving With Anti-Lock Brakes (page 205). Maintenance and Modifications
The suspension and steering systems on
your vehicle have been designed and tested
to provide predictable performance whether
loaded or empty and durable load carrying
capability. For this reason, we strongly
recommend that you do not make
modifications, such as, adding or removing
parts, for example, lowering kits or stabilizer
bars, or by using replacement parts not
equivalent to the original factory equipment.
Any modifications to a vehicle that raise the
center of gravity can make it more likely the
vehicle may rollover as a result of a loss of
control. We recommend that you use caution
with any vehicle equipped with a high load
or device, such as ladder or luggage racks.
Failure to maintain your vehicle properly may
void the warranty, increase your repair cost,
reduce vehicle performance and operational
capabilities and adversely affect driver and
passenger safety. Frequent inspection of
vehicle chassis components is recommended
if the vehicle is subjected to off-highway
usage.

As the distance to the object decreases,
the indicator blocks illuminate and move
toward the vehicle icon.
• If there is no object detected, the
distance indicator blocks are gray.
When you shift into reverse (R), the system
provides audible warnings and visual
indication when detected objects are within
24 in (60 cm) and are inside the driving path
of your vehicle. When you stop your vehicle,
the audible warnings turn off after two
seconds.
When you shift into any forward gear, the
system provides audible warnings and visual
indication when your vehicle is moving at a
speed of approximately
5 mph (8 km/h) or
below and the system detects an object
within the detection zone. When you stop
your vehicle, the audible warnings turn off
after two seconds and visual indication turns
off after four seconds. When you shift into neutral (N), the system
only provides visual indication if your vehicle
is moving at a speed of approximately 5 mph
(8 km/h)
or below. For example, your vehicle
is moving on a slope, and the system detects
an object moving toward your vehicle. When
you stop your vehicle, visual indication turns
off after four seconds.
If the system is not available, the side
distance indicator blocks do not display.
ACTIVE PARK ASSIST
(IF EQUIPPED) WARNING: You must remain in your
