ECU VOLKSWAGEN EOS 2013 1.G User Guide

WARNING
Unsecured or incorrectly stowed items can fly through the vehicle, causing serious personal
injury during hard braking or sharp steering or in an accident. Loose items can also be struck
and thrown through the passenger compartment by the front airbags if they inflate. To help
reduce the risk of serious personal injury:
x Always stow all objects securely in the vehicle. Always put luggage and heavy items in the
luggage compartment.
x Always secure objects in the passenger compartment properly with suitable straps so that
they cannot move into the deployment zone of a side or front airbag during sudden braking,
in a sudden maneuver, or in a collision.
x Always keep storage compartments closed while driving.
x Never stow hard, heavy, or sharp objects in the vehicle's open storage compartments, on
the shelf behind the rear seat bench, or on the top of the instrument panel.
x Always remove hard, heavy, or sharp objects from clothing and bags in the vehicle
interior and stow them securely in the luggage compartment.
WARNING
Transporting heavy objects causes the handling characteristics of the vehicle to change and
increases braking distances. Heavy loads which are not properly stowed or secured in the
vehicle can lead to a loss of vehicle control and cause serious personal injury.
x Transporting heavy items causes the handling characteristics of the vehicle to change by
shifting the vehicle's center of gravity.
x Always distribute luggage evenly and as low as possible within the vehicle. The vehicle
capacity weight figures apply when the load is distributed evenly in the vehicle (passengers
and luggage).
x Always stow luggage and heavy items in the luggage compartment as far forward of the
rear axle as possible and secure them with appropriate straps.
x Never exceed the vehicle's Gross Vehicle Weight Rating or Gross Axle Weight Ratings,
which are printed on the Safety Compliance Certification Label located on the door jamb of
the driver door. Exceeding the permissible weight can cause the vehicle to skid and behave
differently.
x Always adapt your speed and driving style to accommodate your payload and its weight
distribution within your vehicle.
x Be especially cautious and gentle when stepping on the accelerator pedal and avoid
sudden braking and other maneuvers.
x Brake earlier than you would if you were not driving a loaded vehicle.
NOTICE
The defroster heating wires in the rear window can be damaged by objects that rub against
them.

WARNING
Improper use of the trailer hitch can cause accidents and injuries. An improperly installed,
incorrect, or damaged trailer hitch can cause the trailer to separate from the towing vehicle
and cause serious personal injuries.
x Only use an undamaged, properly mounted trailer hitch.
x Never repair or modify the trailer hitch.
x To reduce the risk of injury in rear-end collisions, and the risk to pedestrians and cyclists
when the vehicle is parked, always remove the ball mount when you are not towing a trailer.
x Never install a “weight distributing” or “load equalizing” trailer hitch on your vehicle. The
vehicle was not designed for these kinds of trailer hitches. The trailer hitch attachment can
fail, causing the trailer to tear loose from the vehicle.
WARNING
Improper trailer towing can cause loss of vehicle control and serious personal injury.
x Driving with a trailer and carrying heavy or large things can change the way the vehicle
handles, increase the distance it needs to stop safely, and cause accidents.
x Always secure the load properly with suitable and undamaged straps so that the load will
not shift.
x Always adapt your speed and driving to the heavier load and the weight distribution in the
vehicle. Take road, weather, traffic, and visibility conditions into account as well.
x Reduce your speed even more than you otherwise would when going downhill and under
unfavorable load, weather, or wind conditions.
x Trailers with a high center of gravity tip more easily than trailers with a low center of
gravity.
x Always avoid sudden maneuvers and hard braking.
x Be especially careful when passing other vehicles.
x Reduce speed immediately if the trailer shows the slightest sign of swaying.
x Never try to stop the swaying by accelerating.
x Always obey speed limits. In some areas, the speed limits for vehicles towing trailers are
lower than for vehicles without trailers. Never drive faster than 50 mph (80 km/h; under
exceptional circumstances 60 mph - 100 km/h) when towing a trailer. This applies even if the
local speed limit is higher.
If you are driving a new vehicle or a vehicle with a new or rebuilt engine, do not tow a trailer
during the break-in period, about 600 miles (1000 km)
If you tow a trailer, your vehicle may need maintenance more often because of the extra load it
has to move.
When you are not towing, remove the trailer hitch ball. This helps keep the trailer hitch from
causing damage to your vehicle and to others if your vehicle is hit from behind.
Some models need a trailer hitch to tow or tow-start other vehicles. You may want to always
carry the ball mount in the vehicle after it has been removed. Be sure to stow it securely.

WARNING
Trailer loads that are not properly secured can shift when the vehicle is moving or braking
and suddenly change the way the vehicle handles, causing accidents and severe injuries.
x Always load the trailer properly.
x Always secure the load properly with suitable, undamaged straps that can be tightened so
that the load cannot shift.
Driving with a trailer

x The pin-to-ball distance (B) from the center of the ball to the center of the hole for the securing pin
on the ball mount must be no more than 7 inches (178 mm).
x The ball diameter must be no more than 1 1/4 inches (32 mm).
A ball mount and ball combination that does not meet these specifications can damage your vehicle
and may even fail in use ⇒ .
Never install a “weight distributing” or “load equalizing” trailer hitch on your vehicle. The vehicle is not
designed for this kind of trailer hitch ⇒ .
WARNING
An improperly installed or unsuitable trailer hitch can cause the trailer to separate from the
towing vehicle and result in a major accident with serious personal injuries.
x Have any trailer hitch retrofit or other work on a trailer hitch done by a qualified workshop.
CAUTION
The ball mount sticks out behind the rear bumper and can cause injury to pedestrians and
cyclists.
x To reduce the risk of injury in rear-end collisions, and the risk to pedestrians and cyclists
when the vehicle is parked, always remove the ball carrier when you are not towing a trailer.
NOTICE
x Never use a ball larger than 1 1/4 inches (32 mm) on your vehicle. The vehicle was not
designed to tow heavier trailers with a receiver larger than the specified ball. The increased
loads can damage the attachment points for the trailer hitch.
x Never use an adapter to increase the size of the trailer hitch receiver from 1 1/4 inches
(32 mm) to 2 inches (50.8 mm) or more to tow a trailer that is heavier than the maximum
permissible trailer weight that your vehicle can tow.
x You can use an adapter if required for the proper installation of a bicycle rack or other
similar carrier as long as the maximum weight limits are observed. When using bicycle racks
or similar carriers, make sure that the rear lights are not blocked.
x Only use trailer hitches that are approved by the hitch manufacturer for your vehicle and
model.

WARNING
Objects in the driver footwell can prevent the pedals from moving freely. This can cause loss
of vehicle control and increase the risk of serious personal injuries.
x Always make sure that nothing can interfere with the pedals.
x Always fasten floor mats securely to the floor.
x Never put floor mats or other floor coverings on top of already installed floor mats.
x Always make sure that nothing can fall into the driver footwell while the vehicle is moving.
NOTICE
x The defroster heating wires in the rear window can be damaged by hard or sharp things on
the shelf below the rear window.
x Do not keep any food, medicine, or other items sensitive to heat or cold in the vehicle. They
can be damaged or made unusable by heat or cold.
x Things that are made of transparent materials (such as eyeglasses, magnifying glasses, or
transparent suction cups on the windows) can magnify sunlight and damage the vehicle.

The design of the wheel bolts is matched to the factory-installed wheels. If different wheels are
installed, wheel bolts with the right length and bolt head shape must be used. This helps to ensure that
wheels can be mounted securely and that the brakes will work correctly
In most cases, you cannot use wheel bolts from a different vehicle. Even wheel rims from the same
model may not fit properly.
Tires and wheel rims approved by Volkswagen have been matched precisely to your vehicle model
and contribute considerably to good handling and safe vehicle performance.
Tightening torque
Wheel bolts must always be installed with the correct tightening torque . The required tightening torque
for your vehicle's wheel bolts is 88 ft-lbs (120 Nm). After changing a wheel, the bolt torque must be
checked as soon as possible with an accurate torque wrench. See an authorized Volkswagen dealer
or an authorized Volkswagen Service Facility.
Wheel rims with bolted rim rings
Wheel rims with bolted rim rings have several parts. The parts are bolted together with special screws
in a special process. This helps to ensure that they will work properly, prevent leaks, run true and
safely. Damaged wheel rims must be replaced, and you must never take them apart or try to repair
them yourself. Have an authorized Volkswagen dealer or an authorized Volkswagen Service Facility
repair them for you ⇒ .
Wheel rims with bolted decorative covers
Light-alloy wheels may have interchangeable decorative covers attached to the rim with self-locking
screws. If you want to replace damaged wheel covers, contact your authorized Volkswagen dealer or
authorized Volkswagen Service Facility.
WARNING
Using improper or damaged wheel rims can affect driving safety, cause accidents and severe
personal injury.

WARNING
Improper use of a compact spare wheel can cause loss of vehicle control, a crash or other
accident, and serious personal injury.
x Never use a compact spare wheel if it is damaged or worn down to the wear indicators.
x In some vehicles, the compact spare wheel is smaller than the original tire. A smaller
compact spare wheel is identified with a sticker and the words “50 mph” or “80 km/h.” This is
the maximum permissible speed when driving with this tire.
x Never drive faster than 50 mph (80 km/h) with a compact spare wheel. Avoid full-throttle
acceleration, heavy braking, and fast cornering!
x Never drive more than 125 miles (200 km) if a compact spare wheel is installed on the front
axle (drive axle).
x Replace the compact spare with a normal wheel and tire as soon as possible. Compact
spare tires are designed for brief use only.
x Regularly check the U.S. DOT Tire Identification Number (TIN) to determine the age of the
compact spare wheel . Tires age even if they are not being used and can fail suddenly,
especially at higher speeds.
x Tires that are more than 6 years old can only be used in an emergency and then with
special care and at lower speeds.
x The compact spare wheel must always be secured with the wheel bolts provided by the
factory.
x Never drive using more than one compact spare wheel.
x After installing the compact spare wheel, the tire pressure must be checked as soon as
possible .
x Snow chains cannot be used on the compact spare wheel. If you must use snow chains
and have a compact spare wheel mounted, move the compact spare wheel to the rear axle if a
front tire has to be replaced. The tire taken off the rear axle can then be used to replace the
flat front tire. Be sure you do not change the tire's direction of rotation. Install the snow
chains on the full-sized road tire.
NOTICE
The spare wheel or compact spare wheel has no tire pressure sensor. When the spare or
compact spare wheel is mounted on the vehicle, the Tire Pressure Monitoring System (TPMS)
indicator light will flash in the instrument cluster display .
If possible, attach the compact spare wheel or the tire you took off the vehicle securely in the
luggage compartment.

WARNING
Improper replacement of burned out headlights and other light bulbs can cause serious
personal injury.
x Stop! Always read and heed the WARNINGS before doing any work in the engine
compartment 256. The engine compartment of any motor vehicle is a potentially dangerous
area, and work in this area can lead to serious personal injury.
x HID – High Intensity Discharge (Xenon) headlights get power from a high voltage source
that can cause severe personal injury and even death if handled improperly.
x H7 bulbs and HID – High Intensity Discharge (Xenon) headlights are under high pressure
and can explode if handled improperly.
x Always let a burned out light bulb cool down before replacing it.
x Never replace a light bulb unless you are familiar with all of the necessary procedures. In
particular, never remove a headlight unless you know exactly how to carry out the job and
have the correct tools and light bulbs.
x If you are uncertain about what to do, have the work performed by an authorized
Volkswagen dealer, an authorized Volkswagen Service Facility, or another qualified
workshop. Serious personal injury may result from improperly performed work.
x We strongly recommend that you always have HID – High Intensity Discharge (Xenon)
headlights and H7 bulbs replaced by a qualified technician.
x Do not touch the glass of light bulbs with your bare hands. Fingerprints left on the bulb
evaporate due to the heat when the bulb is switched on and cause the reflector to “cloud.”
x There are sharp edges on and around the headlight housing in the engine compartment
and the rear light housing. Wear hand protection if you replace bulbs.
NOTICE
After replacing a headlight bulb or other light bulb, always make sure that the rubber covers or
plastic caps have been properly and securely reinstalled to help prevent water from getting
into the electrical connections and headlight housing and damaging the electrical system.
