2013 VOLKSWAGEN JETTA HYBRID ECU

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 to the tie-downs provided.
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 or antenna in the rear window can be damaged by objects that rub
against them.
The ventilation slots between the rear window and the shelf behind the rear seat backrest must
not be blocked so that stale air can escape from the vehicle.

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 forward or back 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 forward or back.
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 seat 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 in 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
section.
Luggage compartment pass-through

Fig. 84 In the rear backrest: Opening luggage compartment pass-through.

Opening the pass-through
x Fold down the rear center armrest
x Push down the release button ⇒ fig. 84 (A) and fold the pass-through cover (1) down into the
luggage compartment (B).
x Take the cover out of its bracket and bring it forward into the passenger compartment.
x Stow the cover securely in the luggage compartment.
x Slide long objects from the luggage compartment through the pass-through.
x Secure objects with the safety belt.
x Close the luggage compartment lid.
Closing the pass-through
x Working from the vehicle passenger compartment, guide the pass-through cover (1) into the
luggage compartment and push the release button to engage it in its bracket.
x Pull the cover shut until it locks into place. Make sure it is securely locked into place.
x If necessary, fold the center armrest up.
Tie-downs

Fig. 85 In the luggage compartment: Tie-downs.

WARNING
Unsuitable, worn, or damaged tie-down straps (elastic or non-elastic) can snap or come
loose during braking or other maneuvers or in a collision. Objects secured with these straps
can then come loose and fly through the passenger compartment, causing severe personal
injuries or death.
x To help prevent baggage or other items from coming loose and flying around, always use
suitable undamaged tie-down straps.
x Securely fasten the tie-down straps to the tie-downs.
x Loose or improperly secured objects in the luggage compartment can slide about
suddenly and change the vehicle's handling.
x Secure even small and light objects. Loose objects in the luggage or passenger
compartment can fly about during sudden braking maneuvers or in the event of an accident
and injure occupants.
x Never exceed the maximum allowable load on the tie-downs when securing objects.
x Never secure a child seat to the tie-downs.
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
luggage compartment and then to the tie-downs 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.

Securing a load on the roof rack

WARNING
When powered by the electric motor, the vehicle makes much less noise, both when idling
and driving, than when it is running on the internal combustion engine. It is much harder or
even impossible for the drivers of other vehicles and above all for cyclists, pedestrians, and
children to hear the vehicle when it is running on electrical power.
x Pedestrians and others can be struck and seriously injured because they cannot hear the
vehicle and tell that it is getting close to them, for instance when you are parking, backing up,
or driving in a low-speed zone where there is likely to be pedestrian traffic.
x Always watch out for pedestrians, especially small children, cyclists, and others who may
not hear the vehicle or realize that it is about to move or will cross their path of travel.
x Always be especially careful in residential areas, school zones, and other places where
the speed of motor vehicles is restricted and pedestrians may be at greater risk.
x Make sure the ignition and the hybrid drive system have both been turned off before
leaving the vehicle.
WARNING
Never leave the vehicle when hybrid drive system indicator lights are still lit. The vehicle can
move if the accelerator is depressed even though the combustion engine has been stopped.
This can cause accidents and severe or fatal injuries.
x Make sure the transmission is in Park (P) before you get out of the vehicle.
WARNING
Never support the vehicle with cinder blocks, bricks, or other objects to inspect it. The
vehicle could slip or move suddenly and cause an accident with serious personal injury.
WARNING
Never let the hybrid battery get wet. Liquids and other fluids can cause short circuits,
electrical shock, burns, and explosions.
x Never carry large amounts of liquids or other fluids in the luggage compartment.
x Always make sure that any containers with liquids and other fluids are properly secured
and tightly closed to prevent leakage during normal driving as well as hard cornering,
braking, and other vehicle maneuvers. Leaking liquids can get into the cover of the high-
voltage battery and the high-voltage cable connections. This can damage the electrical
system and the high-voltage battery.
Never drive until the fuel tank is completely empty. There may not always be enough charge in
the high-voltage battery to get to the next gas station.
Warning and display messages

Sailing
If the accelerator is not depressed and the lever is in position D, the combustion engine is switched off,
even at higher speeds. The vehicle then decelerates slower than conventional vehicles. This feature
can be used to help reduce fuel consumption when you keep traffic conditions in mind and can
anticipate the vehicle's power requirements. The instrument cluster powermeter shows zero.
Brake energy regeneration (Recuperation/charge)
When the vehicle brakes, the electrical energy is generated by the electric motor, which works as an
alternator and charges the high-voltage battery. The same thing occurs while the vehicle is coasting to
a stop or driving downhill.
Energy regeneration is shown in the instrument cluster display or on the Infotainment System screen.
The combustion engine may be switched off automatically in this situation. The instrument cluster
powermeter registers below zero.
Automatic starting - combustion engine
The combustion engine is started automatically in a number of situations.
x Engine temperature is too low.
x Catalytic converter temperature is too low.
x The high-voltage battery requires recharging.
x High-voltage battery is being charged at high rate when decelerating. The high-voltage battery
cannot absorb any more energy and for this reason the electric motor cannot brake the vehicle. The
combustion engine comes on to help slow the vehicle down (engine brake).
x Engine hood is open.
x Leaving the vehicle when the electric motor is still “live”. The status of the electric motor is not
always obvious, particularly when the combustion engine is not running. The combustion engine will
therefore start if the driver's safety belt is unlatched or the driver's door is opened when the
transmission is in Park (P) or Neutral (N) .
