2013 VOLKSWAGEN JETTA HYBRID battery

DANGER
The vehicle's high-voltage electrical system and high-voltage battery are dangerous and can
cause burns, other serious personal injuries, electrocution, and death.
x Always assume that high-voltage battery and parts of the high-voltage system are fully
charged and energized.
x Never touch or let jewelry or other metal objects contact high-voltage cables or the high-
voltage battery and battery poles, especially if the cables, battery, and battery poles have
been damaged in any way.
x Never do any work yourself on the high-voltage electrical system, the orange-colored
high-voltage wiring, or on the high-voltage battery.
x Never open, service, repair, or disconnect any part of the hybrid electrical system.
x Never damage the orange-colored high-voltage cables. Never remove them and never
disconnect them from the high-voltage electrical system.
x Never open or remove the orange-colored cover on the high-voltage battery.
x Always have work on the hybrid electrical system and systems that could be indirectly
affected by it done by qualified, trained technicians who have the know-how, experience,
documentation, and tools to do the work safely.
x All work on the high-voltage electrical system and the high-voltage battery must be done
in compliance with Volkswagen standards and guidelines.
x Vehicle keys must be safely stored a safe distance from vehicle so that the ignition cannot
be switched on and energize the electrical system.
x Gases vented or released from the high-voltage battery vapors are potentially poisonous
and can burn.
x Physical damage to the vehicle or the high-voltage battery can result in immediate or
delayed release of poisonous gases that can also cause a fire.
x Always avoid contact with leaking fluids and gases escaping from the battery, particularly
one that has been damaged.
x Always tell emergency responders that the vehicle has a high-voltage battery.
WARNING
Driver distraction causes accidents and serious personal injury. Using the instrument cluster
or accessing Infotainment System menus while driving can take your attention off the road
and cause accidents.
x To help reduce the risk of accidents and injuries, never change settings in the instrument
cluster display or use Infotainment System functions unless the vehicle is standing still.

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

Warning messages
When the ignition is switched on, several warning and indicator lights come on briefly for a function
check. They go out after a few seconds.
Warning lights and text messages are shown in the instrument cluster display. Acoustic warnings may
also sound at the same time.

Warning when leaving the vehicle
Switch off the ignition before leaving the vehicle unattended . In certain situations, a message
Ignition on appears in the instrument cluster display as you are leaving the vehicle. This message
warns you that the vehicle's electric drive is still enabled and that the combustion engine might start
automatically.
Always switch the ignition off, remove the key, and take it with you when leaving the vehicle ⇒ . As
a reminder to do so, the combustion engine may start automatically under the following conditions:
x The ignition is switched ON.
x AND: Electrical drive is functional (Ready).
x AND: The transmission is in Park (P) or Neutral (N).
x AND: The driver safety belt is not fastened OR The driver door is open.
The message in the instrument cluster display also reminds you to switch the ignition off. In addition,
always be sure to apply the parking brake, remove the key, and take it with you when leaving the
vehicle.
WARNING
A parked vehicle that is not properly parked can roll away and cause accidents or severe
injuries. When leaving the vehicle, always move the selector lever into Park (P) and engage
the parking brake.

switched off in this mode. Gentle start-ups (getting the vehicle going) and parking are also phases the
electrical motor can often handle alone.
The combustion engine is started if you accelerate faster or if the charge level of the high-voltage
battery gets too low. As soon as allowed by your acceleration and the high-voltage battery charge
level, the vehicle switches back to electrical motor drive.
Use the following indicators to tell when the vehicle is being powered electrically:
x Instrument cluster display.
x Infotainment System screen.
Extended electro-mode drive (EÊMODE)
By pressing the %

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) .

NOTICE
x Failure to heed warning lights or text WARNINGS can result in vehicle damage.
x If the 12 Volt battery is disconnected or dead or has been replaced, there is a possibility that
the combustion engine will not automatically switch off when the vehicle is powered by the
electric motor. If this situation persists for several days, take the vehicle to an authorized
Volkswagen dealer or an authorized Volkswagen Service Facility that is qualified to do work on
hybrid vehicles.
x Never transport water or other liquids or fluids in open containers, such as an aquarium. If
liquid is spilled in the luggage compartment, this can cause short circuits or damage the high-
voltage battery.
NOTICE
Never block or cover the cooling air vents for the high-voltage hybrid battery under the rear
seat. Blocking or covering these vents can damage the high-voltage battery.
NOTICE
If the vehicle is not used for a longer period, the high-voltage battery will run down. To keep
the high-voltage battery in good condition, the vehicle needs to be driven at least every 2
months for at least 30 minutes or 15 miles (20 km).
x If the high-voltage battery is dead, the gasoline engine will not start. Contact an authorized
Volkswagen dealer, an authorized Volkswagen Service Facility, or another qualified workshop
for assistance.
