WARRANTY and SERVICE
AIRSTREAM INC.
LIMITED WARRANTY
WARRANTY COVERAGE
When you buy a new Airstream Interstate Motorhome from an authorized Airstream dealer, Airstream,
Inc., warrants the motorhome from defects in material and workmanship as follows:
BASIC WARRANTY PERIOD
This warranty is for 30,000 miles (40,000 Kilometers) or two years, whichever comes first, beginning when
the vehicle is delivered to the first retail customer or first placed into demonstrator service. This warranty
must have started prior to the accumulation of 4,000 miles in order to be valid.
ITEMS COVERED
Any part of the motorhome or any component equipment installed by the factory is covered by the basic
warranty except the following items, which are not covered:
• House Battery
• Generator
The above items will be handled by their respective service points and according to their written policy.
This limited warranty does not include failure caused by accident, abuse, normal wear, overload or any
cause not attributable to a defect in original material or workmanship of the motorhome or component
equipment as installed by the factory.
LIMITATION OF IMPLIED WARRANTIES
All warranties of merchantability and fitness for a particular purpose, whether written or oral, express or
implied, shall extend only for a period of two years from the date of original purchase, or 30,000 miles,
whichever comes first. There are no other warranties, which extend beyond those described on the face
hereof and which expressly excludes conditions resulting, from normal wear, accident, abuse, exposure or
overload. Some states do not allow limitation on how long an implied warranty lasts, so the above
limitations may not apply to you.
AIRSTREAM'S RESPONSIBILITY
The basic Airstream Limited Warranty applies for a period of two years from the date of original
purchase or 30,000 miles, whichever comes first, and the application date of all warranties is that indicated
on the owner's identification card. Defects in items covered under this Warranty will be corrected without
cost upon the return, at the owner's expense, of the motorhome or defective part to an authorized Airstream
dealer.
A-1
AIRSTREAM INTERSTATE MOTORHOME OWNERS MANUAL
CARE AND MAINTENANCE
This warranty covers only defective material and/or workmanship; adjustments are made at the factory
prior to shipment, and rechecked by the dealer prior to delivery to the customer. Adjustments thereafter
become a customer responsibility.
The owner is also responsible for following all recommendations, instructions and precautions contained in
the Airstream Motorhome Owner's Manual and the individual manuals furnished by the chassis, appliance
and other manufact urers.
INSTALLATIONS NOT COVERED
Airstream, Inc., does not accept any responsibility in connection with any of its motorhomes for additional
equipment or accessories installed at any dealership or other place of business, or by any other party. Such
installation of equipment or accessories by any other party will not be covered by the terms of this
warranty.
IF REPAIRS ARE NEEDED
If your motorhome needs repairs under the terms of the basic Airstream Limited Warranty, you should:
1. Take your motorhome to your selling dealer or other Authorized Airstream Dealer.
2. If the dealer is incapable of making the repair, request that he contact the Service Administration
Department at Airstream, Inc., for technical assistance.
3. If repairs are still not made, the customer should contact:
AIRSTREAM, INC.
419 W. Pike Street - P.O. Box 629

• The complete serial number of the motorhome
• Mileage
• Date of original purchase
• Selling dealer
• Nature of service problem and steps or service, which have been performed. (The owner
may be directed to another dealer at the owner's expense.)
4. If, after taking the above steps, repairs are still not complete, the Airstream owner may request the
motorhome be allowed t o be brought to t he Factory Service Center at the owner's expense.
DEALER REPRESENTATION EXCLUDED
The full extent of the basic Airstream Limited Warranty is set forth-in detail in the folder, and in the
explanation of the basic Airstream Limited Warranty covered in the Airstream Motorhome Owner's
Manual. Airstream Inc. will not be responsible for additional representations or implied warranties made by
any of its dealers to the extent those representations are not a part of, or are contrary to, the terms and
conditions of the basic Airstream Limited Warranty.
A-2
AIRSTREAM INTERSTATE MOTORHOME OWNERS MANUAL
CONSEQUENTIAL AND INCIDENTAL DAMAGES
Airstream, Inc., will not be responsible for any consequential or incidental expenses or damages
resulting from a defect. Incidental expenses include, but are not limited to: travel expenses, ga so line,
oil, lodging, meals, telephone tolls, and loss of work and loss of use of the motorhome. Some examples
of consequential damages would be: stained curtains due to rain leaks or delaminated floor caused by
a plumbing leak. 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.
WARRANTY TRANSFER
The basic Airstream Limited Warranty is transferable to subsequent owners for the duration of the
warranty period. Warranty transfer application forms are available from your dealer or the Airstream Inc.
Service Administration Department.
CHANGES IN DESIGN
Airstream Inc. reserves the right to make changes in design and improvements upon its product without

AIRSTREAM INTERSTATE MOTORHOME OWNERS MANUAL
WARRANTY EXPLANATION
Along with your new Airstream motorhome you have purchased t he Airstream Limited Wa rranty. Read
your Limited Warranty carefully. It contains the entire agreement with respect to Airstream's obligation on
the Limited Warranty on your new vehicle. The terms of the Limited Warranty, and only those terms, will
define Airstream's responsibility. When you receive your Limited Warranty file it for safekeeping.
Upon proof of purchase date to any Airstream Dealer Service Center, defects in materials or workmanship
will be repaired or replaced without cost to the owner for a period of twenty four (24) months from the
original purchase date, or 30,000 miles, whichever occurs first. Written warranties of some manufacturers
of components of the motorhome will be honored by Airstream for the duration on that manufacturer's
warranty.
The Airstream Limited Warranty Excludes:
Normal Wear:
Items such as water purifier packs, curtains, upholstery, floor coverings, window, and vent seals may show
wear within the one year Limited Warranty period depending upon the amount of usage, weather and
atmospheric conditions.
Accident
Damage caused by accident is usually visible, and we strongly urge our dealers and customers to inspect
the motorhome upon 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's or your responsibility upon
acceptance of the motorhome. 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, including failure to comply with the terms of the
Owner’s Manual, or fa i lure to heed proper vehicle operation shown by the dash instruments is not covered
by warranty.
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.
Appearance
Paint and appearance items that show imperfections, damage to interior and exterior surfaces resulting from
abrasion, collision or impact, and broken window glass is not covered by the Airstream Limited Warranty
and should be brought to the at t ention of your Airstream dealer at the t ime of delivery and during predelivery inspection.
Overload
Overload Damage due to loading beyond capacity or to cause improper balance is not covered by the
Airstream Limited Warranty. The Airstream motorhome 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 motorhome consult your Owner's Manual
or gross vehicl e weight rating plate.

exists in a group of vehicles, it may order a recall and remedy campaign. However, NHTSA cannot become
involved in individual problems between you, your dealer, or Airstream, Inc.
To contact NHTSA you may either call the Auto Safety Hotline toll-free at 1-800-424-9393 (or 366-0123

DRIVING
LOADING
Below is a sample of the weight information chart provided in all Airstream vehicles. This information can
be found in your vehicle on the back of a wardrobe door about 60” up from the floor.
See specification section in this manual for weights and term definitions.
WEIGHT DISTRIBUTION
The motorhomes have fresh water, a wastewater tank, and storage areas. It gives you great flexibility in
loading. With flexibility comes responsibility. If you want to load down all the storage compartments, the
amount of fluids will have to be reduced. Distribute your additional cargo as evenly as possible with the
heaviest objects located as low as possible.
Do you really want to carry 300 pounds of water to a RV park 1,000 miles away and then hook up to a city
water supply? Even if you're going to the "boondocks”, you can usually fill your water tank shortly before
entering the area. Just reducing your load by 10 gallons of water lets you carry an awful lot of fishing and
camping gear.
WEIGHING
The unloaded vehicle weight (UVW), listed on the chart in your coach is the weight of the motorhome with
the options as ordered and installed at the factory. It includes all weight at the axles with full generator
fluids, including fuel, engine oil, and coolants . To determine the actual weight of your vehicle with
personal cargo, water and LP, it must be weighed on scales. The most common scales are those used by
states to weigh trucks used along the highway. In rural areas grain elevators are a good source and another
would be a gravel pit. Note: Weighing instructions for this motorhome are explained later in this section.
If you have trouble locating scales, a call to your State Highway Patrol will usually find them very
cooperative in assisting you.
B-1
AIRSTREAM INTERSTATE MOTORHOME OWNERS MANUAL
SAFETY CHECK LIST
Your Airstream motorhome should be given a thorough safety check before a tri p. Regular use of the
following list will provide safe operation of your motorhome and will help you spot any malfunctioning
equipment and correct the problem as soon as possible. The list is to help you and may not be all-inclusive.
Failure to heed the following items may cause damage to the vehicle or personal injury.
EXTERIOR CHECK LIST (BEFORE ENTERING VEHICLE)
1. Check condition of tires for proper inflation.
2. Turn off LPG valve on LPG tank.
3. Check that sewer connections, city water hookup, TV cable/satellite, and all exterior components
are unhooked and properly stowed away.
4. Check that all external compartments and filler openings are properly closed, latched, and/or
locked.
5. Check that items stored on exterior of vehicle are securely tied down.
6. Would any items stored on exterior of vehicle present a clearance problem?
7. Lower and secure TV antenna, (stow satellite dish).
8. Follow all automotive manufacturers recommendations on checking and filling fluid levels.
9. Check exterior lights and general condition of vehicle.
10. Keep tires at recommended inflation pressure.
INTERIOR CHECK LIST (BEFORE DRIVING OF F)
1. It is important that all doors be completely closed during travel.
2. Turn off living area water pump.
3. Check that refrigerator door is fastened.
4. Check that nothing heavy is stored in overhead or high cabinets, which could fall out and cause
injury. Heavy items should be stored in lower cabinets.
5. Stow folding and pedestal tables.
6. Check that counter tops, range top, and shelves are clear of even small items that could become
projectiles in an accident.
7. Do not cook while under way. Hot food or liquid could scald due to a sudden stop or accident.
8. Be sure all LPG controls on the furnace, range and gas/electric refrigerator are turned Off.
9. Check that any internal stowage is securely held in place
10. Check that lights and switches are set in positions safe for travel.
11. Adjust the driver's seat so that you can easily reach and operate all controls. Make sure seat is
locked in position. Do not adjust driver's seat’ swivel, fore or aft mechanism while vehicle is
moving. The seat could move unexpectedly causing loss of contr ol.
B-2
AIRSTREAM INTERSTATE MOTORHOME OWNERS MANUAL
12. Check that front passenger's seat is locked in position - both fore and aft adjustment and swivel
mechanism.
13. The freedom of movement of the brake and accelerator pedals must not be impaired in any way
14. Check rear view mirrors adjustment, inside and outside. Adjust curtains if necessary for maximum
visibility.
15. Secure children in a Federally Approved Child Restraint Device.
16. Fasten your lap belts.
SAFETY
SEAT BELTS
In the forward driver's area of the motorhome, safety seat belts are provided for the use of the driver and the
right front passenger. Safety belts are available for other seats. It is strongly recommended that all
occupants remain seated with their safety belts firmly attached while the motorhome is in transit. The driver
should adjust his seat so that he is able to reach all controls easily with the belt on, especially able to use all
the travel on the foot brake. The belt should be placed as low as possible around the hips to prevent sliding
out from under them in case of accident. This places the load of the body on the strong hipbone structure
instead of around the soft abdominal area. Two people should never try to use the same seat belt.
Warning:
pertaining to seats, seat belt operatio n, a nd restraint systems, provided in the Sprinter
Operator’s Manual.
Warning:
Device. Failure to use proper restraints while in transit can result in severe or fatal injuries. Never
place an infant seat that faces to the rea r o n t he fr ont passenger seat. Never place an unbelted infant
seat on the front passenger seat.
Child restraint devices are designed to be secured with lap or lap/shoulder belts. All instructions supplied
by the restraint manufacturer must be followed. Statistics have shown children are safer when properly
restrained in a rear seating position than in a front seating position.
Often the children traveling in motorhomes are grandchildren. There are times when our love for
grandchildren makes us hesitate to properly supervise their actions. Don't hesitate when it comes to their
safety. Make sure they are properly restrained.
IF YOU WON'T BUCKLE UP FOR YOURSELF, BUCKLE UP FOR THEM.
Become familiar with and follow all directions, advice, and warnings
Children must be secured in a Federally Approved Child Restraint

Warning:
combination. Even a small amount of alcohol or drugs can affect your reflexes, perception,
and judgment. The possibility of a serious or even fatal accident is sharply increased when you drink
or take drugs and drive. Never drink or take drugs and drive or allow anyone to drive after drinking
or taking drugs.
Drinking or taking drugs and driving can be a very dang erous

TRAILER TOWING AND DRIVING TIPS
Failure to use proper equipment and driving technique can result
Warning
in a loss of vehicle control when towing a trailer. Improper towing or failure to
follow the instructions contained in this section can result in serious injury.
Follow the guidelines below carefully to assure safe trailer operation. Ask your authorized
sprinter or Airstream dealer if you require an explanation of information contained in the
sky.
Trailer Hitches
Only install a trailer hitch receiver approved for your vehicle. For information on av ailability and
installation, please see your authorized Sprinter dealer.
The bumpers on your vehicle are not designed for use with clamp type hitches. Do not attach
rental hitches or other bumper type hitches to them.
To reduce the possibility of damage, remove the hitch ball adapter from the receiver when not in
use.
Electrical Connections
The Sprinter is available with a variety of preinstalled conditions (lines and turn signal indicator
and break module installed and/or not installed). Make sure that correct trailer hitch receiver is
used. For further information, please see your authorized Sprinter or Airstream Dealer.
In order to prevent possible damage to the vehicle's electrical system by incorrectly installing the
trailer-wiring plug, we recommend having the harness connected at an authorized Sprinter or
Airstream Dealer.
Vehicle and Trailer Weights and Ratings
Gross Vehicle Weight Rating (GVWR) is the maximum permissible weight of the motorhome.
Gross Vehicle Weight (GVW): comprises weight of vehicle including fuel, tools, spare tire,
installed accessories, passengers, cargo, and trailer tongue. It must never exceed the GVWR.
Gross Axle Weight Rating (GAWR) is a maximum permissible axle weight.
Gross Trailer Weight (GTW) is a maximum permissible trailer weight to be towed.
Trailer Tongue Weight Rating (TWR) is the maximum permissible weight of the trailer tongue.

AIRSTREAM INTERSTATE MOTORHOME OWNERS MANUAL
Since this vehicle is designed and intended primarily as a load-carrying vehicle, towing a trailer will affect
handling, durability and economy. Maximum safety and satisfaction depends upon proper use of correct
equipment and avoiding overloads and other abusive operation.
Warning:
GCWR listed in the specification section of this manual. The maximum towing capacity
varies according to the size of the motorhome and its GCWR. Vehicles should be properly equipped
for towing trailers. Information on trailer hauling capabilities and special equipment required may
be obtained from your Airstream dealer.
Loading a Trailer
When loading a trailer, you should observe that neither the permissible GTW, nor the GVWR are exceeded.
Maximum permissible values are listed on the safety compliance certification labels for the vehicle and for
the trailer to be towed. For their location, see the Sprinter Operators Manual. The lowest value listed must
be selected when determining how the vehicle and trailer are loaded.
To assist in attaining good handling of the vehicle/trailer combination it is important that the tongue weight
be maintained at approximately 10%-15% of the loaded trailer weight, but not to exceed the hitch rating.
Tongue loads can be adjusted by proper di st ribution of the loa d in the trailer, a nd can be checked by
weighing separately the loaded trail er and then the tongue.
The tongue weight (TW) at the hitch ball must be added to the GVW to prevent exceeding your Sprinter
towed vehicles or rear GAWR.
When towing trailers, motorhome tires should be inflated to the highest pressures shown on the information
plate on the side of the driver’s seal mounting plate. The Cargo Carrying Capacity (CCC) of this vehicle is
reduced by the amount that equals the trailer tongue load on the trailer hitch.
.
The total weight of the motorhome and trailer must not exceed the
Checking Weights of Vehicle and Trailer
To assure that the tow vehicle and trailer are in compliance with the maximum permissible
weight limits, and to know the actual weights, have the loaded vehicle-trailer combination (tow
vehicle including driver, passengers and cargo, trailer fully loaded) weight on commercial scale.
Check the vehicles front and rear Gross Axle Weight (GAW), the GTW and TW. The values as
measured must not be exceeded, according to the weight listed under "Vehicle and trailer weight
and ratings" in this section.

AIRSTREAM INTERSTATE MOTORHOME OWNERS MANUAL
Attaching a Trailer
Please observe maximum permitted trailer dimensions (weight and length).
Most states and all Canadian provinces require safety chains between your tow vehicle and
trailer. The chains should be crisscrossed under the trailer tongue. It must be attached to the
hitch receiver, and not to the vehicles bumper or axle. The sure to leave enough slack in the
chains to permit turning corners.
Most states and all Canadian provinces required a separate brake system had serious trailer
weights.
The towing vehicle’s braking system is rated for operation at
Warning:
GVWR (GROSS VEHICLE WEIGHT RATING), NOT at the GCWR (GROSS
COMBINED WEIGHT RATING). A separate functioning brake system is required for
any towed vehicles or trailers weighing more than 1000 lbs. (450 kg) when fully loaded.
NEVER exceed the GVWR (GROSS VEHICLE WEIGHT RATING), or the GAWR
(GROSS AXLE WEIGHT RATING) specified on a motorhome certification label. Also
NEVER exceed the weight ratings of trailer hitch installed on a motorhome. Failure to heed
any part of this warning could result in loss of control of the motorhome and towed vehicle
or trailer and may cause an accident and serious injury. For specified towed vehicle
braking requirements, consult the Sprinter Operator's manual that comes with this vehicle.
Warning:
directly to the vehicles hydraulic brake system has your vehicle is equipped with
antilock brakes. If you do, neither the vehicles brakes nor the trailers brakes will function
properly. Property damage, injury or death to you or others may be the result. The
provided vehicle electrical wiring harness for a trailer towing has a brake signal wire for
hookup to a brake controller. Most states and all Canadian provinces require a brake away
switch on trailers with a separate brake system. The switch activates the trailer brakes in
the possible event that the trailer might separate from the tow vehicle. He should consider
using a trailer sleigh control system. For further information see your authorized Sprinter
or Airstream dealer.
Towing a Trailer
There are many different laws, including speed limit restrictions, having to do with trailer towing.
Make sure that your vehicle -- trailer combination will be legal; not only for where you reside, but
also for where you'll be driving. He good source for this information can be the police or local
authorities.
Before you start driving with a trailer, check the trailer’s hitch; brake away switch, safety chains,
electrical connections, lighting and tires. Also, adjust the mirrors to permit unobstructed view
beyond rear of trailer.
Do not connect a trailer brake system (if trailer is so equipped)
B-6
AIRSTREAM INTERSTATE MOTORHOME OWNERS MANUAL
If the trailer has electric brakes, start your vehicle and trailer moving slowly, and then apply only
the trailer brake controller by hand to be sure the brakes are working properly.
When towing a trailer, check occasionally to be sure that the load is secure, and that lighting and
trailer brakes (if so equipped) are functioning properly.
Always secure items in the trailer to prevent load shifts while driving.
Take into consideration that when towing a trailer, the handling characteristics are different and
less stable from those when operating the vehicle without a trailer. It is important to avoid
sudden maneuvers.
The vehicle and trailer combination is heavier, and therefore is limited in acceleration inclining
ability, and requires longer stopping distances. It is more prone to reacting to side wind gusts,
and requires more sensitive steering input.
In order to gain skill and an understanding of the vehicles behavior, you should practice turning,
stopping in backing up in an area which is free from traffic.
If possible, do not brake abruptly, but rather engage the brake slightly at first to permit trailer to activate its
brake. Then increase the braking force.
We want every owner to be a safe and courteous driver. A few hours of towing practice in a large empty
supermarket lot will make pulling your trailer over the road much easier. Line out two corners for left and
right turns. You may also use these corners to practice backing and parking.
OBSERVE THAT THE TRACKS MADE BY THE TRAILER WHEELS ARE DISTINCTLY
DIFFERENT FROM THOSE MADE BY THE TOW VEHICLE. Studying this will make it easier for you
to correct mistakes. Truck or trailer type fender or door grip rear view mirrors are necessary for maximum
visibility and in most states the law requires them.
After thoroughly inspe cting your hitch, brakes, and tires you should be ready to tow. Check traffic, signal
that you are about to pull away, and start slowly. Look often in your mirrors, and observe the action of the
trailer, then carefully move into the proper lane of traffic. Remember that the trailer wheels will not follow
the path of the tow vehicle wheels; therefore, WIDER TURNS ARE NECESSARY WHEN TURNING TO
THE LEFT OR TO THE RIGHT.
ON FREEWAYS OR EXPRESSWAYS try to pick the lane you want and stay in it. Always maintain
plenty of space between you and the car ahead, at least the length of the tow vehicle plus trailer for every
ten miles per hour. Remember that in order to pass another vehicle you will need longer to accelerate. You
must also allow for the length of the trailer when returning to the right hand lane.
B-7
AIRSTREAM INTERSTATE MOTORHOME OWNERS MANUAL
Tracking
On a two-lane road cars will be lining up behind you because you travel at a lower speed. It is both
courteous and sensible to signal, pull onto the shoulder, and let them pass.
The BRAKE CONTROLLER (if so equipped) is activated when you apply the brakes of the tow vehicle.
Your tow vehicle brakes will automatically apply the trailer brakes first when properly adjusted. This will
help keep your tow vehicle and trailer in a straight line and make you stop as if you were driving the tow
vehicle alone. If swaying or swerving should occur, briefly operating the controller separate from the
vehicle brakes may help correct the situation. Practice this maneuver on a clear highway. Don't wait for an
emergency then grope for the controller.
When trailering you might encounter a temporary cooling system overload during severe conditions such as
hot days when pulling on a long grade, when slowing down after higher speed driving, or drivi ng long idle
periods in traffic jams. If the hot indicator light comes on, or the temperature gauge indicates overheating
and you have your air conditioner turned on, turn it off. Pull over in a safe place and put on your emergency
brake. Don't turn off the engine. Increase the engine idle speed. Lift the engine hood and check for fluid
leaks at the radiator overflow outlet. Check to see that all drive belts are intact and the fan is turning. If you
have a problem have it fixed at the next opportunity. If there is no problem the light should go off or
temperature should come down within one minute. Proceed on the highway a little slower. Ten minutes
later resume normal driving.
WARNING
level when the vehicle is cool.
When going downhill in dry weather, down shift so that engine compression will slow the whole rig clown.
Take dips and depressions in the road slowly and do not resume normal driving speeds until you are sure
that the trailer wheels are clear of the dip.
WARNING
cause the rear wheels of the tow vehicle to skid. On icy pavement drive slowly and if you feel the tow
vehicle skidding gently apply the trailer brakes only. This will bring the tow vehicle and trailer back
into a single line. Chains do not help trailer wheels.
: Never open a radiator cap when the tow vehicle is hot. Check the coolant
: On slippery pavement do not use engine drag to help slow down as this may
B-8
AIRSTREAM INTERSTATE MOTORHOME OWNERS MANUAL
When driving in mud and sand let the momentum carry the rig through. Apply power gently and use as
little as possible. Stay in the tracks of the vehicle ahead and keep the tow vehicle in the highest possible
gear. If you are stuck it is best to tow out the entire rig together without unhitching.
Despite the best hitch you will notice that whenever a large bus or truck overtakes your rig the displaced air
first pushes the trailer rear slightly to the right and then affects the front. It may be necessary to steer very
slightly, momentarily, toward the bus or truck to help compensate for the sway induced by the passingvehicle. Do not apply the vehicle brakes, as this can tend to exaggerate the situation. You may find,
however, that briefly applying the trailer brakes with your manual control will help eliminate sway.
WARNING:
enough for standstill safety. CHOCK THE TRAILER WHEELS to he double sure. Do not use trailer
brakes as parking brakes.
Backing Up
In BACKING UP the important thing to remember is to DO EVERYTHING SLOWLY and to correct
immediately if you see the trailer turning the wrong way. Concentrate on the rear of the trailer. With your
tow vehicle and trailer in a straight line, back up slowly and turn the bottom of the steering wheel in the
direction you want the trailer to go. Watch out the window or in the mirror until the rear of the trailer is
pointing in the desired direction. Your tow vehicle will be following the trailer in an arc. Straighten the tow
vehicle and trailer by turning the steering wheel more sharply, and then when they are in line, straighten the
steering wheel.
ALWAYS TRY TO BACK TO YOUR LEFT BECAUSE THE VISIBILITY IS MUCH BETTER. (See
Illustration) When you don't make it on the first try it is usually much easier to pull forward to your original
position and start over.
If your spouse or traveling companion normally directs you when backing they should position themselves
forward of the tow vehicle so the driver can easily see them. Their directions should always indicate to the
driver the direction the rear of the trailer should go. A little practice in a parking lot with the person giving
directions can save a lot of frustration when backing into a campsite.
WARNING:
When stopping on a hill or slope, leaving your tow vehicle in gear is not
take into consideration that when towing a trailer, the
handling characteristics are different and less stable from those with operating
the vehicle without a trailer. It is important to avoid sudden maneuvers. Sudden
maneuvers may lead to loss of control over the vehicle -- trailer combination.
CAUTION
If the transmission hunts between gears on inclines, manually shift to a lower
:
gear (select "4", "3", "to "2" or "1"). A lower gear and reduction of speed reduces the chances of
engine overloading and/or overheating. When going down a long hill, shift into a lower gear and
use the engines braking effect. Avoid riding the brakes, thus overheating the vehicle and trailer
brakes. If the engine coolant rises to an extremely high temperature (coolant temperature needle
approaching the red zone) when the air conditioner is on, turn off the air conditioner. Engine
coolant heat can be additionally vented by opening the windows, switching the climate control
fan speed to high and setting the temperature control to the maximum hot position. Extreme care
must be exercised censure vehicle with a trailer will require additional passing distance ahead that
when driving without a trailer. Because your vehicle and trailer is longer then your vehicle alone,
you will also need to go much further ahead of the passed vehicle before you can return to your
lane.

Parking
WARNING:
vehicle power train, as a result of vehicle/trailer movement, always:
• Keep right foot on the brake pedal.
• Shift tear selector lever to position "N".
• Have a second person place wheel chocks on downhill side of left and right trailer

• Slowly release brake pedal cannot vehicle and trailer roll into chocks until stopped.
• Firmly depress parking brake pedal.
• Move gear selector lever to position "P".
• On inclines, turn from wheels towards the road curb.
TOWING YOUR MOTORHOME
The most common equipment is called "reach under hooks". These allow the tow operator to lift on the
front suspension of your motorhome without damaging the bumper or other body parts. Another choice is a
wheeled dolly. In these, the front tires sit in a cradle supported by its own wheels. The tow operator should
be told the weight of your vehicle on the front suspension so they can be properly prepared when they reach

the braking and steering systems. In this case, it is important to keep in mind that a
considerably higher degree of effort is necessary to brake and steer the vehicle. The vehicle
must not be towed with the front axle raised and key in position two in the ignition lock as

IMPORTANT INFORMATION
Your Sprinter Van Operator’s and Warranty Manuals contain important cautions,
warnings, operational, and warranty information on the Sprinter and its components. All
information in the Sprinter manual should be reviewed and followed for your safety. The
Airstream Interstate Owner’s Manual may provide addition information and tips on the
use of the Van as a motorhome, however, no information in the Airstream manual should
be interpreted as advice or directions to disregard or void the warnings, cautions, or other
information contained in the Sprinter’s manuals.
TIRES
Don't let anyone tell you that underinflation or over inflation is all right. It's not. If you're tires
don't have enough air (underinflation) you can get tire flexing, heat build-up, tire overloading,
bad handling, bad fuel economy, and bad wear. Too high an air pressure (over inflation) can
result in abnormal wear, bad handling, harsh ride, and also increase the chance of damage from
road hazards.
Tire inflation pressures should be checked at least monthly and when significantly changing the
load you plan to carry in your motorhome. Always check tire inflation pressures when the tires
are "cold".
Standard inflation pressures for tires are listed on a decal mounted on the driver’s seat pedestal.
Front and rear pressures are shown for each model and GVWR, and are based on the GVWR and
front and rear axle ratings (GAWRs) printed on your vehicle VIN plate and Certification label.
Tires must be inflated to these pressures when the vehicle is fully loaded or an axle GAWR is
reached.
Proper FRONT END ALIGNMENT improves tire tread mileag e. Your front- end suspension parts
should be inspected periodically and aligned when needed. Improper alignment may or may not
cause the vehicle to vibrate. However, improper toe alignment will cause front tires to roll at an
angle, which will result in faster tire wear. Incorrect caster or camber alignment will cause your
front tires to wear unevenly and can cause the vehicle to "pull" to the left or right.
The following section is intended to provide information on tires and how improper care and
maintenance may affect your vehicle, its performance, and your safety. If you have any questions
on your tires please contact a qualified tire service center or an authorized Sprinter dealer.
C-3
AIRSTREAM INTERSTATE MOTORHOME OWNERS MANUAL
Tire Identification Number
Just about everything you need to know about a tire can be found on its sidewall. Each letter and
number conveys important information, like whether a particular tire will be compatible with
your vehicle. The represented in the drawing is not used on Airstream Inc. products and is for
examples only.
Some size designations are preceded by a letter indicating what type of vehicle the tire is
intended. "P," which stands for "passenger," is the most common. "LT," which stands for "light
truck," is also common.
The first number (215 in this example) is a three-digit number, which refers to the overall width
of the tire, in millimeters.
The second number (65) refers to the aspect ratio, which is the relationship between the tire's
height and it's width. In this example, the sidewall's height is about 65% of the tire's width.
The letter following the aspect ratio is usually an "R," standing for "radial."
The next number indicates the diameter of the wheel rim on which the tire will fit (15 inches, in
this example).
The final number and letter represent the service description, or load index and speed rating. The
load index is an assigned number ranging from 0 to 279 that corresponds with the load carrying
capacity of the tire; that is, how much weight it is certified to carry at maximum inflation
pressure. The rating can be matched against a load index chart to determine corresponding
maximum weights. A load index rating of 89 indicates a maximum load of 1,279 lbs.
C-4
AIRSTREAM INTERSTATE MOTORHOME OWNERS MANUAL
The speed rating is a letter, which indicates the range of speeds at which a tire is certified to carry
a load (see the speed symbols chart to determine your tire's maximum speed). Each tire is
assigned a rating from A (lowest) to Z (highest). There is one notable exception: the "H" rating
falls out of sequence between "U" and "V," and is used for tires certified for speeds up to 130
mph. The Q rating is the lowest commonly used for passenger cars. An "H" -rated tire is certified
up to 210 km/h or 130 mph. See Load Index and Speed Rating Charts in this section for further
information.
Just to recap. A tire marked P215/65R15 89H would have a width of 215 millimeters and an
aspect ratio of 65. It would be a radial tire sized for a rim with a 15-inch diameter, feature a load
index of 89 (capable of carrying a maximum load of 1,279 pounds) and a speed rating of "H"
(indicating it is certified up to 130 miles per hour).
It's important to note that markings do not always appear exactly as they do in this example, as
tires can be certified under a variety of designations.
Uniform Tire Quality Grading Standards
Also on the sidewall is The Uniform Tire Quality Grade (UTGQ), which offers three more key
pieces of information about a tire:
Tread wear:
Tread wear is a critical indicator of how much longer your tire will last. In the life of every tire,
tread eventually degrades to a degree where the tire can no longer be used safely.
Each type of tire is tested under controlled conditions on a government test course and assigned a
tread wear grade, which theoretically indicates the useful life of the tread. It's important to
remember that this is a theoretical figure and cannot be linked to projected tire mileage, as
factors like road surface quality, driving habits, inflation, wheel alignment and rotation come into
play.
Tread wear grades typically range from 60 to 620 in 20 point increments. The higher the grade,
the longer the tread life as measured under government conditions.
Traction:
Traction grades indicate a tire's braking perform ance. Traction is tested in a straight-ahead motion
on wet pavement. A grade from "A" to "C" is assigned, with "A" signifying the best traction.
Temperature:
Temperature grades represent a tire's ability to withstand heat under test conditions. Since tires
are made of rubber and other materials, which are degraded by high levels of heat, determining
their ability to withstand heat is very im portant. Temperature grades are also assigned A- C w ith A
signifying the most resistance to heat.
C-5
AIRSTREAM INTERSTATE MOTORHOME OWNERS MANUAL
Other Markings
Maximum Load, Maximum inflation
For passenger tires, the maximum load and maximum inflation markings indicate the maximum
load that can be carried at the maximum pressure. For light truck tires, it is stated in direct
relationship to the maximum load capacity and inflation pressure.
DOT Markings
Essentially the DOT marking serves as the tire's fingerprint. DOT signifies that the tire complies
with U.S. Department of Transportation Tire Safety Standards, and is permitted for highway use.
For example refer to the following markings: DOT M5H3 459X 064. The first letter and number
following DOT designate the tire's manufacturer and plant code. The third, fourth and fifth
number and letter, 59X, is the tire size code which is an optional manufacturers code that
identifies the tire size and other specific characteristics of the tire. The final three numbers denote
when the tire was produced, with the first two indicating the week, and the last number indicating
the year (064 indicates the tire was built in the 6th week of 1994).
