Safety Precautions
Many things can be construed as safety related, but
the most important is your common sense� If you are
careless with matches, cigarettes, ammable material,
or any other hazardous material, you surely realize
your potential for accidents is greatly increased�
You will nd many safety recommendations in this
section and throughout the manual� The following
recommendations are the ones we consider to be the
most important�
Weight Distribution
Touring coach’s have fresh water and wastewater
tanks, a water heater, and storage areas� It gives
you great exibility in loading. With exibility comes
responsibility� If you want to load down all the storage
compartments, the amount of uids may have to be
reduced� It is a trade off so plan wisely� Distribute
your additional cargo as evenly as possible with the
heaviest objects located as low as possible�
Do you really want to carry a full freshwater tank to
a RV park 1,000 miles away and then hook up to a
city water supply? Even if you’re going to a remote
area, you can usually ll your water tank shortly
before entering the area� Just reducing your load by
10 gallons of water lets you carry an additional 83�5
pounds of cargo�
Tire Safety
Properly maintained tires improve the steering,
stopping, traction, and load-carrying capability of your
vehicle� Refer to Section 9 - Maintenance for tire care
and safety information� Also, be sure to read the Tire
Safety Manual Addendum included with your owner’s
packet�
Appliances and Equipment
The appliances (stove) and equipment (hot water
heater, furnace, generator, etc�) typically operate on
liqueed petroleum (LP) gas. LP gas is ammable and
is contained under high pressure� Improper use may
result in a re and/or explosion. Make sure to follow
all instructions and warnings in this manual as well as
those in the specic owner’s manuals of the appliances
and equipment�
Generator Safety
Do not operate the generator in an enclosed building or
in a partly enclosed area, such as a garage� Be sure to
follow all instructions and warnings in this manual and
the generator manufacturer’s manual� Refer to Section
5 - Interior for generator information�
Mold
Mold and mold spores exist throughout indoor and
outdoor environments� There is no practical way
to eliminate all mold and mold spores in the indoor
environment; however, the way to control indoor
mold growth is to control moisture� Refer to Section
3 - General Information for information on controlling
condensation and molds�
Chemical Sensitivity and Ventilation
Chemical Sensitivity
Immediately after the purchase of your new
recreational vehicle and sometimes after it has been
closed up for an extended period of time, you may
notice a strong odor and/or experience a chemical
sensitivity� This is not a defect in your recreational
vehicle� Like your home, there are many different
products used in the construction of recreational
vehicles, such as carpet, linoleum, plywood, insulation,
upholstery, etc� Formaldehyde is also the by-product of
combustion and numerous household products, such
as some paints, coatings, and cosmetics� However,
recreational vehicles are much smaller than your home
and therefore, the exchange of air inside a recreational
vehicle is signicantly less than in a home. These
products, when new or when exposed to elevated
temperatures and/or humidity, may off-gas different
chemicals, including formaldehyde� This off-gassing,
in combination with the minimal air exchange, may
cause you to experience irritation of the eyes, nose,
and throat, as well as sometimes headache, nausea,
and a variety of asthma-like symptoms� Elderly persons
and young children, as well as anyone with a history
of asthma, allergies, or lung problems, may be more
susceptible to the effects of off-gassing�
2-2 2020 Interstate
Safety
Formaldehyde
Formaldehyde is a naturally occurring substance and
is an important chemical used widely by industries
to manufacture building materials and numerous
household products� It is also a by-product of
combustion and certain other natural processes�
Thus, it may be present inside the touring coach�
Ventilation of the unit normally reduces the exposure to
a comfortable level�
Trace levels of formaldehyde are released from
smoking, cooking, use of soaps and detergents, such
as carpet shampoos and cosmetics, and many other
household products� Some people are very sensitive to
formaldehyde while others may not have any reaction
to the same levels of formaldehyde� Amounts released
decrease over time�
Your Airstream touring coach was manufactured using
low formaldehyde-emitting (LFE) wood products,
the use of which is typical in the recreation vehicle
industry� Formaldehyde has an important role in
the adhesives used to bind wood products used in
recreation vehicles� The wood products in your coach
are designed to emit formaldehyde at or lower than
industry guidelines and should not produce symptoms
in most individuals�
While LFE wood products typically do not emit
formaldehyde at a level that would cause symptoms
in most individuals, it is possible, though not likely,
for symptoms to occur when the touring coach is
not properly ventilated� Ventilation is an essential
requirement for touring coach use for many reasons�
Any effects of formaldehyde can be greatly reduced
by actions such as opening windows, opening roof
vents, running the air conditioner, or some combination
thereof� In addition, the emission of formaldehyde by
these products naturally decreases rapidly over time�
Airstream strongly suggests you take measures to
properly ventilate your touring coach on a regular
basis� If you have any questions with respect to proper
ventilation of your touring coach, please do not hesitate
to contact your dealer or Airstream�
Ventilation
To reduce or lessen exposure to chemicals from
off-gassing, it is of the utmost importance that you
ventilate your recreational vehicle� Ventilation should
occur frequently after purchase and at times when the
temperatures and humidity are elevated� Remember,
off-gassing is accelerated by heat and humidity� Open
windows, exhaust vents, and doors� Operate ceiling
and/or other fans, roof AC, and use a fan to force stale
air out and bring fresh air in. Decreasing the ow of
air by sealing the recreational vehicle increases the
formaldehyde level in the vehicle’s indoor air�
Do Not Smoke
It is recommended you do not smoke inside your
recreational vehicle� In addition to causing damage
to your recreational vehicle, tobacco smoke releases
formaldehyde and other toxic chemicals�
Medical Advice
Questions regarding the effects of formaldehyde on
your health should be submitted to your doctor or local
health department�
Alarms and Detectors
Parts of this section on the Smoke Alarm and Carbon
Monoxide Detectors are a reprint of the manual
included with each device and provided to you in the
Airstream owner’s briefcase� Please read, understand,
and follow all aspects of the complete manual before
activating and operating the Smoke Alarm and Carbon
Monoxide Detectors� If you have not received the
manuals, contact your dealership to obtain one, or
contact Airstream Customer Relations at 937-596-6111�
NOTE
Dangers, Warnings, and Cautions alert you to
important operating instructions or to potentially
hazardous situations. Pay special attention to
these items.

cause a false alarm�
• Alarm should be tested once per week� If further
details are required, which do not appear in this
manual, contact BRK Brands Inc� First Alert�
WARNING
Activation of your Carbon Monoxide alarm’s
audible horn indicates the presence of Carbon
Monoxide that can kill you. Leave the area
immediately!
2-4 2020 Interstate
Safety
What Is Carbon Monoxide
Carbon Monoxide (CO) is a highly poisonous gas that
is released when fuels are burned� It is invisible, has
no smell, and is therefore very difcult to detect with
the human senses� Under normal conditions, in a room
where fuel-burning appliances are well maintained and
correctly ventilated, the amount of CO released into the
room by appliances is not dangerous�
These fuels include wood, coal, charcoal, oil, natural
gas, gasoline, kerosene, and propane� Common
appliances are often sources of CO� If they are not
properly maintained, are improperly ventilated, or
malfunction, CO levels can rise quickly� CO is a real
danger in air-tight vehicles with added insulation,
sealed windows, and other weatherproong that can
trap CO inside�
The following conditions can result in potentially dangerous CO situations
1� Excessive spillage or reverse-venting of fuel-
burning appliances caused by outdoor conditions,
such as:
• Wind direction and/or velocity, including high
gusts of wind�
• Heavy air in the vent pipes (cold/humid air with
extended periods between cycles)�
Symptoms of Carbon Monoxide Poisoning
• Mild Exposure - Slight headache, nausea, vomiting,
fatigue (u-like symptoms).
• Medium Exposure - Throbbing headache,
drowsiness, confusion, fast heart rate�
• Extreme Exposure - Convulsions, unconsciousness,
heart and lung failure� Exposure to CO can cause
brain damage and/or death.
WARNING
Smoke and CO Alarms are shipped with batteries
deactivated. Ask dealer to activate batteries or
activate batteries immediately upon delivery.
Failure to follow warning will remove your
protection.
WARNING
Many causes of reported CARBON MONOXIDE
POISONING indicate that while victims are aware
that they are not well, they become so disoriented
that they are unable to save themselves by either
exiting the area or calling for assistance. Also
young children and pets may be the rst to be
affected.
• Negative pressure differential resulting from
use of exhaust fans�
• Simultaneous operation of several fuel-burning
appliances competing for limited internal air�
• Vent-pipe connections vibrating loose from
clothes dryers, furnaces, or water heaters�
• Obstructions in or unconventional ventpipe designs which can amplify the above
situations�
2� Extended use of un-vented fuel burning devices�
3� Temperature increase that can trap exhaust gases
near the ground�
WARNING
Test Units in your touring coach after the vehicle
has been in storage, before each trip, and at least
once a week while in use. If the alarm ever fails to
test correctly, have it replaced immediately. If the
alarm is not working properly, it cannot alert you
to a problem. Failure to test units used in RVs as
described may remove your protection.
2020 Interstate 2-5
Safety
Regular Maintenance
The smoke alarm and CO detector have been
designed to be as maintenance-free as possible, but
there are a few simple things you must do to keep them
working properly� Use only the replacement batteries
recommended� The units may not operate properly with
other batteries� Never use rechargeable batteries since
they may not provide a constant charge�
• Test it at least once a week�
• Clean the Smoke and CO Alarms at least once a
month: gently vacuum the outside of the Smoke
and CO Alarms using your household vacuum’s soft
brush attachment� A can of clean, compressed air
(sold at computer or ofce supply stores) may also
be used� Follow manufacturer instructions for use�
• Test the Smoke and CO Alarms once a week�
Never use water, cleaners, or solvents, since they
may damage the unit�If the Smoke and CO Alarms
becomes contaminated by excessive dirt, dust, and/
or grime, and cannot be cleaned to avoid unwanted
alarms, replace the unit immediately�
• Relocate the unit if it sounds frequent unwanted
alarms�
WARNING
The battery door will resist closing unless batteries
are installed. This warns you that the unit will not
operate without batteries. The Smoke and CO
Alarms cannot operate without working batteries.
Removing the batteries for any reason, or failing to
replace the batteries at the end of their service life,
removes your protection.
WARNING
Carbon Monoxide is poisonous and can cause
confusion, unconsciousness, and death. Follow all
instructions, cautions, and warnings in this section
and the generator operator’s manual.
WARNING
NEVER ignore any alarm. Failure to respond can
result in injury or death. The Silence Features are
for your convenience only and will not correct a
problem. Always check your touring coach for a
potential problem after any alarm. Failure to do so
can result in injury or death.
Basic Generator Safety Information
1� Never sleep in the vehicle with the generator
running without ensuring the Carbon Monoxide
detector is working� Primary protection against
inhaling Carbon Monoxide is daily (every eight
hour) inspection for visible and audible generator
exhaust system leaks�
2� DO NOT operate the generator in an enclosed
building or in a partly enclosed area such as a
garage�
3� Review the safety precautions for fuel and exhaust
fumes in the generator manual�
4� DO NOT operate the generator when the
recreation vehicle is parked in high grass or brush�
Heat from the exhaust could cause a re in dry
conditions�
5� DO NOT simultaneously operate generator and a
ventilator which could result in the entry of exhaust
gas� When exhaust ventilators are used, we
recommend that a window on the opposite side of
the unit “upwind” of exhaust gases be opened to
provide cross ventilation�
6� When parked, orient the vehicle so that the wind
will carry the exhaust away from the vehicle� DO
NOT open nearby windows, ventilators, or doors
into the passenger compartment, particularly those
which can be “down wind”, even part of the time�
7� DO NOT operate the generator when parked in
close proximity to vegetation, snow, buildings,
vehicles, or any other object that could deect the
exhaust under or into the vehicle�
8� DO NOT touch the generator when running,
or immediately after shutting off� Heat from the
generator can cause burns� Allow the generator to
cool before attempting maintenance or service�
WARNING
Your Touring Coach is equipped with an Automatic
Generator Start System. Exposure to carbon
monoxide, moving parts, and electricity hazards
are possible due to unexpected automatic starting.
NOTE
The generator is located under the touring coach
in front of the spare tire. The spare tire may have to
be lowered to access the service door. See spare
tire instructions in the Sprinter section of this
manual.
2-6 2020 Interstate
Safety
Liquid Propane Gas (LPG) Detector
This detector has a seven-year life; see end-of-life
notication in LPG detector manual. Please read the
entire detector manual before operating the unit�
The LPG detector is located in the galley area� LPG
is a mixture of gases produced and sold commercially
as a fuel for heating and cooking appliances� LPG is
highly ammable and, as a result, can be explosive if
ignited under certain circumstances� LPG is heavier
than air and, if conned in a closed space, will
accumulate close to the oor. The LPG detector is
designed to alarm at less than 25 percent of the legal
explosive limit� It will provide a visual and audible alarm
by sounding an alarm every 5 seconds and lighting the
red light emitting diode (LED)�
Your LPG detector is wired directly to your touring
coach battery and incorporates a 1-amp, in-line fuse�
It has no internal battery backup� In normal stand-by
mode, the LED indicator will be green�
Low Voltage
The operating voltage for the detector is 12 VDC� The
actual voltage supplied to the detector in a recreational
vehicle may drop below the minimum 8 VDC� The
detector provides the user with a low voltage warning
before reaching that level and will provide additional
distinct, clear warnings and alarms after the 8 VDC
level is reached� However, if available power supplied
to the unit is below the operating voltage of 8 VDC,
the detector will not detect gas or provide protection
against dangerous levels of LPG�
Detector Test
The Test/Reset button is used to verify proper alarm
function� Executing the test function sounds the alarm
and illuminates the red LED� The test will sound the
alarm twice, with 4 beeps in 1 second, followed by 5
seconds of silence� By pressing the button, you can
verify that the alarm sounds and the LED functions
properly�
WARNING
Activation of this detector indicates the possible
presence of LPG, which can cause an explosion
and/or re, causing serious injury or death. This
normally indicates a leak in the LPG installation or
an LPG appliance. Extinguish all open ames, open
your windows and door, and evacuate the unit
immediately. Do not activate any electrical switch.
Turn off the LPG using the remote shut off switch.
Do not re-enter your unit until a qualied repair
technician has corrected the problem and certied
the system as safe.
WARNING
It is not recommended that the detector be
disconnected from the battery during periods of
storage. There is a small heater on the sensor of
the device that burns away impurities in the air
during periods of normal use. During periods when
power is interrupted, impurities can build up on the
sensor. When power is returned to the detector,
the detector alarm may activate until the impurities
are burned off. This could take a number of hours,
during which time the alarm will be constantly on.
WARNING
Have a qualied technician check your LPG system
annually or if you detect any signs of leaks or
malfunctions.
NOTE
Refer to Section 5 - Interior and Section 6 -
Exterior for additional LPG warnings and safety
information.
2020 Interstate 2-7
Safety
Basic LPG Safety Information
A warning label has been positioned in the cooking
area to remind you to provide an adequate supply of
fresh air for combustion� Unlike homes, the amount
of oxygen supply is limited due to the size of the
recreational vehicle, and proper ventilation when
using the cooking appliances will avoid dangers of
asphyxiation� It is especially important that cooking
appliances not be used for comfort heating as the
danger of asphyxiation is greater when the appliance is
used for long periods of time�
Portable fuel burning equipment, including wood and
charcoal grills and stoves, shall not be used inside
the recreational vehicle� The use of this equipment
inside the recreational vehicle may cause res or
asphyxiation�
A Warning Label has been located near the LP
gas container� This label reads: DO NOT FILL
CONTAINER(S) TO MORE THAN 80% PERCENT
OF CAPACITY. Overlling the LP gas container can
result in uncontrolled gas ow that can cause a re
or explosion. A properly lled container will contain
approximately 80 percent of its volume as liquid LP
gas�
If you smell gas
• Extinguish any open ames, pilot lights and all
smoking materials�
• Do not touch electrical switches�
• Shut off the gas supply using the remote shut off
switch�
• Open doors and other ventilating openings�
• Leave the area until odor clears�
• Have the gas system checked and leakage source
corrected before using again�
LP gas regulators must always be installed with the
diaphragm vent facing downward� Regulators that
are not in compartments have been equipped with a
protective cover� Make sure that regulator vent faces
downward and that cover is kept in place to minimize
vent blockage that could result in excessive gas
pressure causing a re or explosion.
The regulator at the LP tank is under a gray, plastic
cover� The protective cover helps to keep the vent on
the regulator from being clogged by wasps or ice, but
the regulator should be checked regularly to make sure
the vent remains clear�
WARNING
DO NOT store LP containers within vehicle. LP
containers are equipped with safety devices that
vent gas should the pressure become excessive.
WARNING
DO NOT use cooking appliances for comfort
heating. Cooking appliances need fresh air for safe
operation. Before operation, open overhead vent or
turn on exhaust fan and open window.
WARNING
Do not attempt to seal regulator cover.
WARNING
Check vent each time tank is lled to make sure it
is clear of obstructions.
WARNING
Have a qualied technician check your LP Gas
system annually or if you have any signs of leaks
or malfunctions.

Fire Extinguisher
The re extinguisher should be checked for charge on
a regular basis� Make sure your family, especially the
cook, knows how to release the extinguisher storage
bracket and how to properly operate the extinguisher�
Check with your local re department for professional
advice on its operation and use if you nd the
directions on the extinguisher unclear� They will be able
and willing to assist you and your family�
WARNING
Read the directions carefully on the re
extinguisher. If there is any doubt on the operation
you and your family should practice, then replace
or recharge the extinguisher. You will nd your
local re department will be happy to assist you
and answer any questions.
Emergency Exit
There are three avenues of escape from the touring
coach in the event of an emergency, the driver’s door,
the passenger door, and the sliding side cargo door�
As always, safety should be one of your top priorities�
Make sure you and everyone traveling with you can
operate these doors and exit rapidly without light� A
little planning and a quick practice session at each
camping site is well worth the time it may take�
WARNING
At each campsite, make sure you have not parked
in such a manner as to block the operation of the
doors or the escape avenues by being too close to
trees, fences, or other impediments. Scenic views
are one reason for traveling, but do not park so
the beautiful lake or steep cliff is just outside your
doors. Do not block access to the doors from the
inside or outside of the vehicle.
Other safety information on the LPG system of your
touring coach is located in the Plumbing Section of this
manual�
WARNING
Do not smoke in bed. Keep matches out of reach
of small children. Do not clean with ammable
material. Keep ammable material away from open
ame. We have all heard these warnings many
times, but they are still among the leading causes
of res.

General Information
Limited Warranty Policy
This Limited Warranty Covers
(i) The rst retail owner and any subsequent owners
(ii) ONLY those portions of a NEW motorhome not
excluded under the section “What is Not Covered”,
when sold by an authorized dealership and used
for its intended purpose of recreational travel and
camping; and, (iii) ONLY defects in workmanship
performed and/or materials used to assemble those
portions of your motorhome not excluded under the
section “What is Not Covered”� “Defect” means the
failure of the workmanship performed and/or materials
used to conform with the design and manufacturing
specication and tolerances of Airstream. The Limited
Warranty is transferable and the subsequent owner’s
warranty coverage period shall be the unexpired
balance of the original warranty coverage period� A
completed copy of the Warranty Transfer Form must be
submitted to Airstream at the time of resale�
When you request and accept the performance of
warranty repairs under the terms of this Limited
Warranty, you are accepting all terms of this Limited
Warranty, including by way of example, warranty
limitations and disclaimers, the forum selection clause
and the clause reducing the time period when suit must
be led for breach.
If any term of condition in this limited warranty conicts
with your state’s Uniform Commercial Code (“UCC”) as
interpreted by courts within your state, the provisions
of your state’s UCC are varied as allowed for by USS
1-302�
Coverage Ends
36 months after the rst retail owner rst takes delivery
of the motorhome from an authorized dealership or
after the odometer reaches 36,000 miles, whichever
occurs rst. Any action for breach of this warranty or
any implied warranties must be commenced not more
than 37 months after breach� Some states do not allow
the reduction of the time when a breach of warranty
claim must be commenced, so the reduction in time
when a breach of warranty claim must be commenced
may not apply to you�
Limitation Of Implied Warranties
Implied warranties arising under applicable law, if
any, including but not limited to implied warranties of
merchantability or tness for a particular purpose, are
hereby limited in duration to the term of this limited
warranty and are limited in scope of coverage to those
portions of the motorhome covered by this limited
warranty� There are no express warranties or any
implied warranties of merchantability on those portions
of the motorhome excluded from coverage� There is
no warranty of any nature made by airstream beyond
that contained in this limited warranty� No person has
authority to enlarge, amend or modify this limited
warranty� The dealer is not Airstream’s agent� Airstream
is not responsible for any undertaking, representation
or warranty made by any dealer or others beyond
those expressly set forth within this limited warranty�
Some states do not allow limitations on how long an
implied warranty lasts, so the above limitations may not
apply to you�
Disclaimer Of Incidental And Consequential Damages
Airstream disclaims any and all incidental and
consequential damages, including but not limited
to expenses such as transportation to and from
dealerships and Airstream repair facilities, loss of time,
loss of pay, loss of use, inconvenience, commercial
loss (including but not limited to lost prots), towing
charges, bus fares, vehicle rental, service call
charges, gasoline expenses, incidental charges such
as telephone calls and facsimile transmissions, and
expenses for lodging and moisture damage such
as mold and mildew as well as rust and corrosion�
This disclaimer is independent of any failure of the
essential purpose of any warranties provided with the
motorhome, and shall survive any determination that
a warranty failed of its essential purpose� Some states
do not allow the exclusion or limitation of incidental
or consequential damages, so the above limitation or
exclusion may not apply to you�
Repair Remedy
Airstream’s sole and exclusive obligation is to repair
any covered defects discovered within the warranty
coverage period if: (1) within 10 days of your discovery
of a defect you notify Airstream OR an authorized
dealership of the defect; AND (2) you deliver your
Motorhome to Airstream OR an authorized dealership
at your cost and expense�
Back-Up Remedy
If the primary repair remedy fails to successfully
cure any defect after a reasonable number of repair
attempts, your sole and exclusive remedy shall be to
have Airstream pay an independent service shop of
your choice to perform repairs to the defect OR if the
defect is incurable, have Airstream pay diminution in
value damages� The repair remedy and the back-up
3-2 2020 Interstate
General Information
remedy must both be exhausted and these remedies
must fail to fulll their essential purpose before you can
seek any legal or equitable relief� This limited warranty
is not a warranty that promises or extends to future
performance because the warranty does not make a
representation on how your motorhome will perform in
the future but instead represents only what the remedy
will be if a defect exists�
Unless prohibited by state law, repairs will not extend
the time when you must commence a breach of
warranty claim and shall not extend the warranty
coverage period� Any performance of repairs after
the warranty coverage ends OR any performance of
repairs to those portions of your motorhome excluded
from coverage shall be considered “good will” repairs�
Warranty repairs should be expected� Airstream
may use new and/or remanufactured parts and/or
components of substantially equal quality to complete
a repair� Damage to interior or exterior surfaces, trim,
upholstery and other appearance items may occur
at the factory during assembly, during delivery of the
motorhome to your selling dealer or on the selling
dealer’s lot� Normally, any damage is detected and
corrected at the factory or by the selling dealer during
the inspection process� If you discover any damage
when you take delivery of your motorhome, you MUST
notify your dealer OR Airstream within 10 days of
the date of purchase to have damage repaired at no
cost to you� Minor adjustments, such as adjustments
to the interior or exterior doors, drawers, latches
will be performed at no cost to you by your selling
dealer during the rst 90 days of warranty coverage;
thereafter, such adjustments are your exclusive
responsibility as normal maintenance�

General Information
Accident
We strongly urge our dealers and customers to inspect
the touring coach upon receipt of delivery for any
damage caused by accident while being delivered to
the dealer, or while it is on the dealer’s lot� Damage
of this nature becomes the dealer or customer’s
responsibility upon acceptance of delivery, unless
Airstream is notied and the person making the
delivery veries the damage. Glass breakage, whether
obviously struck or mysterious, is always accidental
and covered by most insurance policies�
Abuse
Lack of customer care and/or improper maintenance
will result in early failure for which Airstream cannot be
held responsible�
Exposure
Deterioration by sunlight is possible to such items as
tires, curtains or upholstery� Steel or metal surfaces are
subject to the elements, causing rust and corrosion that
is normal and beyond the control and responsibility of
Airstream�
Overload
Overload Damage due to loading beyond capacity
or to cause improper balance is not covered by the
Airstream Limited Warranty� The Airstream Touring
Coach is engineered to properly handle any normal
load� There are limits to the amount of load that can
be safely transported depending upon speed and road
conditions� If these limits have been exceeded, the
Airstream Limited Warranty will not cover resulting
damage� For additional information on the load
capacity of your touring coach, consult your Sprinter

by its manufacturer before delivery to Airstream� All
service to the Sprinter Van and its components must

Service
Before leaving the factory, every vital part of the touring

Reporting Safety Defects
If you believe your vehicle has a defect which could
cause a crash or could cause injury or death, you
should immediately inform the National Highway Trafc
Safety Administration (NHTSA), in addition to notifying

3-6 2020 Interstate
General Information
8� Keep sharp or hard articles securely packed�
9� Do not pack things in the passenger seating area�
You will need the maximum space for comfort�
10� Wear easy wash, drip-dry traveling clothes�
11� Do not make your vacation trips a mileage
marathon� Stop and relax frequently�
12� Verify rst aid kit provided in passenger door is
complete and up to date�
13� Carry your pet’s dish, food, leash, and health and
registration papers�
Overnight Stop
In time you will develop a knack for spotting wonderful
little roadside locations by turning off the main highway
and exploring� There are many modern recreational
vehicle parks, including State, County, and Federal
parks with good facilities, where you may obtain
electrical, water, and sewer hookups and connections�
Directories are published which describe in detail these
parks and tell what is available in the way of services
and hookups�
All you need to do to enjoy the self-contained luxury is
to:
1� Turn on LP gas supply and light appliance pilots if
required�
2� Turn on water pump and open faucets until air is
expelled from the system�
Before moving on, turn off the LP gas and water pump�
Check your campsite, both for cleanliness and to be
sure you have not left anything behind� Make sure
everything is properly stowed�
Overnight or Weekend Trips
On overnight or weekend trips, chances are you will
not use up the capacity of the holding tanks� Deplete
the water supply if using the system moderately or
conservatively� You will need to maintain the level of
your battery during this time� If your battery falls to 60
percent capacity, charge the battery by starting your
generator�
WARNING
Frequently depleting the battery below 60%
capacity will shorten its lifespan.
Longer Trips
On a longer trip, when you have stayed where sewer
connections and utility hookups were not available, it
will be necessary for you to stop from time to time to
dispose of the waste in the holding tank and replenish
the water supply� Many truck stops and gas stations,
chain and individually owned, have installed sanitary
dumping stations for just this purpose� Booklets are
available that list these facilities�
When you stop for the night, your Airstream Touring
Coach is built to be safely parked in any spot that
is relatively level and where the ground is rm. Your
facilities are with you� You are self-contained� Try to
pick as level a parking spot as possible�
Extended Stay
Making a long trip is not very different from making
a weekend excursion� Since everything you need is
right at hand, you are at home wherever you go� When
packing for an extended trip, take everything you need,
but only what you need�
Hook up to water by attaching a ½ -inch minimum highpressure water hose to the city water service�
Plug the 120-volt, 30-amp Electrical Cable into the City
Power Service� Be sure you have the wire grounded
and have the proper polarity�
To use the generator, you simply start it� All switching is
done automatically� The generator can be started from
any of the Multiplex Systems control panels� It is easier
on your generator and appliances if you’ll allow the
generator to reach its normal operating speed (about a
minute) prior to applying heavy current loads�
Your Touring Coach is equipped with an Automatic
Generator Start System (AGS)� The purpose of an
AGS system is to automatically start (and run) the
generator when the 12 volt electrical system (house
batteries) drops to a pre-determined level� See Section
5 for more information on the AGS System�
A Cable/Satellite TV connection is located in the
exterior compartment along with the switches for the
dump valves, macerator pump, and macerator pump
high-pressure hose reel�
Turn on the gas supply� Lighting a top range burner
to bleed any air from the system will make it easier to
start other appliances including the furnace�
When you stay for extended periods where electric
or water hookups are not available, you must make
regular checks on the condition of your 12-volt battery
2020 Interstate 3-7
General Information
and the contents of your water tank (Multiplex control
panel or SeeLevel II Monitor Panel)� Carry drinking
water in a clean bucket to rell your tank. When your
waste tank nears capacity, move your touring coach to
a dumping location�
Leveling
When you plan to stay in the same place for several
days, weeks, or months, you will want your touring
coach to be as level as possible� Check the attitude
with a small spirit level set on the inside work counter� If
a correction is necessary, then you must rst level from
side to side� This can be done most easily by driving up
a small ramp consisting of 2 in� x 6 in� boards tapered
at both ends� Airstream does not recommend placing
tires in a hole for leveling� Refer to Section 7 - Sprinter
Van for more information on tires�
For units equipped with the optional hydraulic leveling
system refer to Section 6 - Hydraulic Leveling System
for more information�
Effects of Prolonged Occupancy
Your touring coach was designed primarily for
recreational use and short-term occupancy� If you
expect to occupy the touring coach for an extended
period, be prepared to deal with condensation and
the humid conditions that may be encountered� The
relatively small volume and tight compact construction
of modern recreation vehicles mean that the normal
living activities of even a few occupants will lead to
rapid moisture saturation of the air contained in the
touring coach and the appearance of visible moisture,
especially in cold weather�
Just as moisture collects on the outside of a glass
of cold water during humid weather, moisture can
condense on the inside surfaces of the touring coach
during cold weather when relative humidity of the
interior air is high� This condition is increased because
the insulated walls of a recreation vehicle are much
thinner than house walls� Estimates indicate that two
adults can vaporize up to one-and-a-half gallons of
water daily through breathing, cooking, bathing, and
washing� Unless the water vapor is carried outside
by ventilation or condensed by a dehumidier, it will
condense on the inside of the windows and walls as
moisture, or in cold weather as frost or ice� It may also
condense out of sight within the walls or the ceiling
where it will manifest itself as warped or stained
panels� Appearance of these conditions may indicate
a serious condensation problem� When you recognize
the signs of excessive moisture and condensation in
the touring coach, action should be taken to minimize
their effects�
NOTE
Your touring coach is not designed, nor intended,
for permanent housing. Use of this product for
long term or permanent occupancy may lead
to premature deterioration of structure, interior
nishes, fabrics, carpeting, and drapes. Damage or
deterioration due to long-term occupancy may not
be considered normal, and may under the terms of
the warranty constitute misuse, abuse, or neglect,
and may therefore reduce the warranty protection.
To avoid condensation problems, try to follow these tips
to help alleviate excess moisture:
Allow excess moisture to escape to the outside when
bathing, washing dishes, hair drying, laundering, and
using appliances and non-vented gas burners� Always
use an exhaust fan when cooking�
Keep the bathroom door closed and the vent or window
open when bathing and for a period of time after you
have nished.
If you are experiencing condensation, you may want to
reconsider hanging wet clothes in the touring coach to
dry�
In hot weather, start the AC early as it removes excess
humidity from the air while lowering the temperature�
Keep the temperature as reasonably cool during cold
weather as possible� The warmer the vehicle, the
more cold exterior temperatures and warm interior
temperatures will collide on wall surfaces, thus creating
condensation�
Use the ceiling vent to keep air circulating inside the
vehicle so condensation and mildew cannot form in
dead air spaces� Allow air to circulate inside closets
and cabinets (leave doors partially open)� Please
keep in mind that a closed cabinet full of stored goods
prevents circulation and allows the exterior temperature
to cause condensation�
The natural tendency would be to close the vehicle
tightly during cold weather� This will actually compound
the problem� Simply put, you need to remove some

of the warm air and allow some cool outside air to get
inside the vehicle so the furnace will not recycle the
humid interior air�
Minimize the use of incandescent lights, which produce
heat and contribute to condensation�
About Molds
What are molds
Molds are microscopic organisms that naturally
occur in virtually every environment, indoors and
out� Outdoors, mold growth is important in the
decomposition of plants� Indoors, mold growth is
unfavorable� Left unchecked, molds break down
natural materials, such as wood products and fabrics�
Knowing the potential risks is important for any type of
homeowner to protect their investment�
What factors contribute to mold growth
For mold growth to occur, temperatures, indoor or
outdoors, must be between 40°F and 100°F and also,
there must be a source of moisture, such as humidity,
standing water, damp materials, etc� Indoors, the most
rapid growth occurs with warm and humid conditions�
How can mold growth be inhibited
By controlling relative humidity, the growth of mold
and mildew can be inhibited� In warm climates, use
of the air conditioner will reduce the relative humidity�
Vents are located in the bathing and cooking areas
and constant use is advised during food preparation
and bathing, even during colder weather� Additionally,
opening a window during these activities will assist in
ventilation� In extremely humid conditions, the use of
a dehumidier can be helpful. If using a dehumidier,
please read and follow all manufacturer instructions
and recommendations to the use and cleaning of the
dehumidier.
Waste Water System
The main parts of the waste water system are the
toilet, dual holding tanks, and tank dump valves (see
Section 9 - Maintenance for dump valve information)�
The system is designed to provide complete selfcontained toilet facilities, while on the road or parked,
without being connected to a sewage line� It may also
be used when parked while connected to a sewage
hose�
Keep the dump valves closed with either method and
empty the tanks when they are nearly full� The idea is
to send a large volume of water through the tanks and
hose at the same time to oat solids away.
After the sewage tank has been emptied, close the
gate valves and put approximately 5 gallons of water
in the sewage holding tank using the black tank ush
inlet� This will spray the interior of the tank with water
and help prevent solids from building up in the sewage
holding tank� The addition of a deodorizing agent like
Aqua-Kem will help prevent odors�
Should you ever have a buildup of solids, close the
valves, ll the tanks about 3/4 full with fresh water,
drive a distance to agitate the solids, and drain the
tanks�
Things Not to Put into Toilet or Drains
• Facial tissues (they do not dissolve like toilet paper)�
• Automotive antifreeze, ammonia, alcohols, or
acetone�
• Table scraps or other solids that may clog the drains�
Frequent use of your touring coach or cleaning
regularly is an important preventive measure� Further,
any spills should be wiped up quickly and dried as soon
as possible� Avoid leaving damp items lying about�
On safe surfaces, use mold or mildew killing cleaning
products� Check sealants regularly, and reseal when
necessary to avoid water leaks� Proper preventive
maintenance to the touring coach and its accessories,
as described both in this manual and in accompanying
literature, will provide the best protection to the touring
coach�

Winter Traveling
Traveling in sub-freezing temperatures will require
certain precautions to protect the plumbing system
and your personal belongings from being damaged by
freezing�
Some states do not allow LPG to be turned on while
moving� While traveling in these states, simply use
your common sense� How cold is it? How long will
it be before you can turn the heat back on? Is the
temperature dropping or rising? Remember, when
driving at 50 MPH, the wind chill factor will cause the
interior of the touring coach to cool much faster than a
touring coach that is parked�
1� You must have a plentiful supply of propane gas as
the heat from the furnace warms the touring coach
and keeps the fresh water lines and black water
holding tank from freezing�
2� If your stay is longer than overnight, you should
endeavor to have 120-volt electricity available� The
house battery, fully charged, will not last more than
about 15 hours in freezing weather, less (4 hours)
with use of the tank heating pads� Of course, you
can run your generator to recharge the battery, or
even use the generator continually� Keep an eye
on your LP Gas or engine fuel according to the
type of generator your touring coach is equipped
with� Since the generator starts off the house
battery, it is recommended to start the generator
prior to running the battery down�

3� Minimize use of electricity if 120-volt power source
is not available�
4� Leave cabinet doors, wet bath doors, and
wardrobe doors slightly open at night to allow
circulation of air in and around all components�
5� Save 12-volt power by using non-toxic RV-
approved antifreeze in gray water holding tank
instead of heating pad to prevent freezing� Quantity
of antifreeze needed will vary with ambient
temperature and the amount of liquids in tank�
6� For extended stays in cold weather, insulate all
water lines outside the touring coach� You should
remember that low temperatures in combination
with high winds cause an equivalent chill
temperature much below what your thermometer is
reading� For instance, with an outside temperature
of zero degrees, and the wind velocity of 10 miles
per hour, the equivalent chill temperature is -20°F�
7� Remember to remove and drain the exterior
shower faucet to prevent freeze damage�
3-10 2020 Interstate
General Information
Heated Tanks
The Interstate Touring Coach has 12-volt heat pads
installed with the fresh and gray water tanks to help
prevent freezing� The tank pads are controlled by either
of the touch screen Multiplex control panels located in
the front or rear of the touring coach� When the outside
temperature is near freezing, simply switch “ON” the
holding tank heaters� Built-in sensors will activate the
heat pads when the contents of the tanks drop to 44°F�
Once the liquid is heated and rises to 64°F the heat
pads will automatically deactivate� Switch the power
“OFF” when the ambient outside temperature remains
above freezing or if the tanks are empty� Battery power
will last about 4 hours unless the unit is plugged into
an external AC power source or the generator is ran
to operate the inverter/charger� To conserve battery
power, RV antifreeze may be used to protect the gray
and black tanks�
NOTE
The black tank is installed above the oor where
heat from the furnace will keep it from freezing.
NOTE
Drain and winterize all models if the water systems
are not being used during winter traveling. Refer
to Section 9 - Maintenance in this manual for
winterizing instructions.
Safety
As always, safety should be a top priority� Ensure
that you, and everyone traveling with you, can quickly
operate the main door and the emergency exit window
in the dark� Plan for other means of escape in case
these designated exits are blocked�
The escape windows(s) are identied by their red
release handles� To release the escape windows, lift up
on both latches, push on the glass, and swing it clear�
WARNING
The window operation should be checked before
each trip and the latches lubricated with silicon
spray or an equivalent lubricant every 3 months.
WARNING
Read the directions on the re extinguisher
carefully. If you have any doubts as to its
operation, you and your family should practice,
and then replace or recharge the extinguisher. Your
local re department will be able to assist you and
answer any questions.
WARNING
Do not smoke inside the touring coach. Keep
matches out of reach of small children. Do not
clean with ammable material. Keep ammable
material away from open ame. Always shut off the
LP gas at the bottles when fueling a tow vehicle.
We have all heard the above warnings many times,
yet the situations or occurrences they discuss are still
among the leading causes of res.
