ECU VOLKSWAGEN PASSAT 2013 B8 / 6.G User Guide

WARNING
Improper folding and improper latching of the rear seat backrest can cause serious personal
injury.
x Always make sure there are no people or animals in the area around the rear seat backrest
when folding it forward.
x Never fold the rear seat backrest up or down while the vehicle is moving.
x When folding the rear seat backrest back up, make sure that the safety belt does not get
caught or damaged.
x Keep hands, fingers, feet and other body parts out of the way when folding the rear seat
backrest up and down.
x Each rear seat backrest must be securely latched in the upright position so that the safety
belts on the rear seats can provide protection. This is particularly the case for the middle seat
on the rear bench.
x If a seat is used with an unsecured backrest, the passenger will move forward together
with the rear seat backrest during sudden braking, driving maneuvers, or a collision.
x No one, including children, may ride on the rear seats if the rear seat backrest is folded
down or not correctly latched.
NOTICE
Before folding the rear seat backrest forward, adjust the front seats so that the rear seat's head
restraint or backrest cushion will not touch the front seats.
There is a separate release lever in the luggage compartment for each rear seat backrest sec-
tion.
Luggage compartment pass-through

Fig. 112 In the rear seat backrest: Opening luggage compartment pass-through without lock.

WARNING
Elastic straps have to be stretched when being attached to the tie-downs in the luggage
compartment. Hooks on these straps can cause serious personal injury if not handled
properly and attached securely.
x Always protect eyes and face from injury from the hooks when attaching them to the tie-
downs in the luggage compartment.
x Always hold the hooks on elastic straps firmly when attaching to the vehicle and do not let
them snap back and hit you.
x First attach the hooks on the straps to the tie-downs at the rear seat backrest in the lug-
gage compartment and then to the tie-down hooks near the loading edge of the luggage
compartment. This way, if one of the hooks on the elastic straps snaps back, it will move
away from you, decreasing the risk of personal injury.
The maximum load for the tie-downs is about 785 lbs. (356 kg).
For suitable straps and luggage stowage systems, please see an authorized Volkswagen dealer
or authorized Volkswagen Service Facility.

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 gravi-
ty.
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 ex-
ceptional 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 17/8 inches (47.6 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 17/8 inches (47.6 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 17/8 inches
(47.6 mm) to 2 inches (50.8 mm) or more than 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.

Closing the engine hood
x Lift the hood slightly ⇒ .
x Take out the hood support and clamp it in place in its bracket C.
x Lower the hood by hand until it is about 1 ft. (30 cm) above its latch and then let it drop into place
to latch it. Do not push down on it afterwards!
If the hood does not close completely, open it again and close it properly.
When the hood is properly closed, you can see that it fits flush with the other body parts. The indicator
light in the instrument cluster will go out.
WARNING
If the hood is not closed properly, it could fly up and block your view while you are driving.
This can lead to a crash and serious personal injuries.
x After closing the engine hood, check that the hood release lever is properly latched into
the hood latch. The engine hood must be flush with the surrounding auto body parts.
x If you ever notice that the hood latch is not properly secured when the vehicle is moving,
stop at once and close it.
x Never let anyone get in the way of the hood when closing it.
NOTICE
x Make sure the windshield wiper arms are resting on the windshield before you open the
hood. Otherwise, the windshield wipers and the hood may be damaged.
x Always put the windshield wiper arms down against the windshield before driving the
vehicle.
NOTICE
Before opening or closing the engine hood, make sure there is enough room to do so, for
example when the vehicle is in a garage.

WARNING
Working on the batteries or the electrical system in your vehicle can cause serious acid
burns, fires, explosions, or electrical shocks. Always read and heed the following WARNINGS
and safety precautions before working on the batteries or the electrical system.
x Before working on the electrical system, always switch off the ignition and all electrical
consumers and disconnect the negative (-) cable from the standard 12 Volt battery.
x When you change a light bulb, always switch off the light first.
x Always keep children away from battery acid and vehicle batteries in general.
x Always wear eye protection. Never let battery acid or lead particles come into contact with
your eyes, skin, or clothing.
x Sulfuric battery acid is very corrosive. It can burn unprotected skin and cause blindness.
Always wear protective gloves and eye protection. To reduce your risk of injury, never tilt the
batteries, as this could spill acid through the vents and burn you.
x If you get battery acid in your eyes or on your skin, immediately rinse with cold water for
several minutes and then get immediate medical attention. If you swallow any battery acid,
get medical attention immediately.
x When disconnecting the batteries from the vehicle electrical system, always disconnect
the negative cable (-) first and then the positive cable (+).
x Always switch off all electrical consumers before reconnecting 12 Volt batteries.
Reconnect the plus cable (+) first and then the negative cable (-). Never reverse the polarity of
the connections. This could cause a fire.
x A highly explosive mixture of gases is given off when the battery is being charged.
x Do not smoke and avoid fires, sparks, and open flames when working. Never create
sparks or electrostatic charges when handling cables and electrical equipment. Never short
circuit the battery terminals. High-energy sparks can cause serious personal injury.
x Never use or attempt to charge a damaged or frozen battery, or a battery that was frozen
but has thawed. Charging a frozen or thawed battery could cause explosions and chemical
burns! Replace damaged or frozen vehicle batteries immediately. A dead battery can freeze at
temperatures around +32 °F (0 °C).
x If the battery has a vent line or tube, make sure that it is properly connected to the battery.
x Always make sure that the vent line is securely attached to a vehicle battery that is located
in the luggage compartment.
