Volkswagen Jetta Hybrid (2015 year). Instruction - part 16

Driving situa-

tions

Requirements and

conditions

Vehicle behavior

Constant driving

and

gliding without

engine on (sail-

ing).

– Think ahead when

driving, with careful

acceleration.

The kinetic energy of the vehi-

cle is used optimally for its

motion ahead. No energy is

lost through excessive accel-

eration or braking.

– Reduce speed early

or completely in case

of obstacles or speed

limits.

By easing off the accelerator

completely, the combustion

engine is automatically

switched off and disconnected.

The vehicle glides (sails) with-

out engine power, and friction

losses are minimized.

Full acceleration

(Boost).

– Selector lever in

position D.

Accelerator fully de-

pressed or kick-down

acceleration activat-

ed.

The electric motor assists the

combustion engine in accelera-

tion. The maximum overall

output is used briefly

– Selector lever in

position S or

Tiptronic:

accelerator is de-

pressed to 80%.

Braking energy

regeneration

(Recuperation).

– Early and even

braking with short

brake pedal travel.

The vehicle is braked by the

electric motor. Most of the
kinetic energy is then won

back and can be stored in the

form of electrical energy in the

high-voltage battery

Driving in city

traffic.

– Select a moderate

speed.

Driving in fully electric mode at

this level is possible with a

constant speed of up to about

37 mph (60 km/h) on a flat

road surface.

Driving situa-

tions

Requirements and

conditions

Vehicle behavior

– Avoid full accelera-

tion.

The fuel consumption is re-

duced with moderate accelera-

tion due to higher efficiency of

the combustion engine and

driving in fully electric mode is

possible.

– Careful use of the

button

⇒

fig. 123

The high-voltage battery dis-

charges quickly with the

button switched on. This can

increase fuel consumption

since driving in electric mode is

preferred in this case, even

though the combustion engine

would be more efficient.

Driving on coun-

try roads

and highways.

– Consciously ease

off of the accelerator,

to enable longer sail-

ing distance.

By easing off the accelerator,

the combustion engine is au-

tomatically switched off and

de-clutched. The vehicle glides

without engine power.

– Reduce speed by

easing off the accel-

erator early and not

by braking.

Sailing possible. Reduction of

speed this way is more fuel-

efficient than through braking.

– Avoid speeds over

about 80 mph

(130 km/h)

Efficient sailing is possible with

speeds up to about 80 mph

(130 km/h).

– Careful selection of

gear S.

Sporty driving style with acti-

vated sport program increases

fuel consumption. Efficient

sailing in sport program with

combustion engine automati-

cally switched off is possible

with speeds up to about

45 mph (70 km/h).

Driving situa-

tions

Requirements and

conditions

Vehicle behavior

Driving in cold

months.

– Do not warm up the

combustion engine by

running it with the

vehicle stationary.

The temperature of the com-

bustion engine increases very

slowly, but fuel consumption

increases considerably.

– Careful use of heat-

ing for the rear win-

dow, outside mirror,

and front seats.

This prevents energy loss and

saves energy for the electric

motor.

– Leave the vehicle in

a garage overnight.

This prevents the high-voltage
battery and the vehicle interior

from cooling down too much.

The optimal temperature of the
high-voltage battery is reached

quicker at the beginning of the

journey and the combustion

engine can be switched off

quicker when the vehicle inte-

rior is sufficiently heated.

Hybrid functions and modes

Fig. 123 In the lower center console:

button for full electro-mode drive.

Fig. 124 Hybrid menu in the instrument cluster display: Current electric power level.

Please first read and note the introductory information and heed the WARNINGS

The functions and operating modes described below are controlled automatically by the vehicle man-
agement system depending on how the vehicle is being driven. This helps to ensure that the vehicle
operates in the best mode at all times. Full electro-mode drive (

) is an exception, however. The

driver must manually select this mode

⇒Full electro-mode drive (

Combustion engine drive

In this mode, the vehicle is powered by the combustion engine. The electric motor acts as an alterna-
tor and recharges the vehicle's high-voltage battery. It also supplies the 12 Volt power system at the
same time.

A message may also appear in the instrument cluster to let you know that the combustion engine is
active.

Electrical motor drive

The vehicle can be powered by the electrical motor at low to moderate speeds, provided the high-
voltage battery charge is adequate and wind resistance is not too strong. The combustion engine is
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:

Instrument cluster display.
Infotainment System screen.

Full electro-mode drive (

)

By pressing the

button

⇒

fig. 123

, the driver can extend the normal limits of electrical motor

drive so that the electric motor powers the vehicle whenever possible (given the battery charge level
and the way you are driving). In this mode, the vehicle is propelled by the electric motor as much as
possible.

Full electro-mode drive can be activated only if all of the following conditions apply:

The high-voltage battery must have an adequate charge.
The transmission must not be in Sport (S) or Tiptronic mode.

The speed must be below 45 mph (70 km/h).

If full electro-mode drive is not possible, a message appears in the instrument cluster display.

The

symbol in the instrument cluster display indicates that full electric mode is active

⇒ Instru-

ment cluster.

The combustion engine starts and interrupts full electro-mode drive if the first condition changes or
the driver accelerates too heavily. The symbol

in the instrument cluster changes from the large

(activated) display to a smaller (standby) display. Full electro-mode drive resumes automatically as
soon as all of the conditions listed above apply again. The symbol

in the instrument cluster

changes back to the larger display to indicate that the full electro-mode drive is active.

Full electro-mode drive is deactivated if any of the following conditions apply:

Ignition is switched off.

button is pushed a second time.

Transmission is in Sport Drive (S).

Transmission is in Tiptronic mode.
Speed is greater than about 45 mph (70 km/h).

To reactivate, press the

button again.

Electric power level display (E-Powermeter)

The electric power level is shown in the Instrument cluster display

⇒

fig. 124

(arrow). When the power

level display reaches the maximum, the vehicle automatically switches to the combustion engine. By
accelerating gently it is possible to drive the vehicle using electric energy only.

The power level display only appears when the vehicle is being driven with the electric motor.

In all other driving modes, the power level display is deactivated so that the bar is not shown.

Automatic starting - combustion engine

The combustion engine is started automatically in a number of situations:

  The engine temperature is too low.
  The catalytic converter temperature is too low.
  The vehicle's climate control settings require high heat output.
  The high-voltage battery requires recharging.
  The 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).

The engine hood is open.
The driver attempts to leave 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)

⇒ Warning when leaving the vehicle.

The combustion engine runs briefly at sporadic intervals for on-board diagnosis.

Full-acceleration (Boost)

For full acceleration, the vehicle is powered by the combustion engine and the electric motor. This
Boost mode is available only for a short period because it uses a lot of the battery's charge.

Boost mode is activated by:

  Using the kick-down feature when the transmission is in Drive (D).
  OR: Heavy acceleration when the transmission is in Sport drive (S).
  OR: Heavy acceleration when the transmission is in Tiptronic mode.

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.

When the high voltage battery is fully charged, there is no brake energy recuperation, and therefore no
engine braking. Recuperation and engine braking are also automatically reduced if the vehicle detects
that the road conditions do not permit sufficient contact between the wheels and the road surface.

Start-Stop mode

The combustion engine is operated only as needed. When the vehicle is stopped the combustion
engine is normally off. The vehicle electrical systems are supplied with power from the high-voltage
battery. The instrument cluster powermeter shows zero.

This dependant on vehicle conditions feature of the hybrid drive system is normal and is designed to
save fuel. The power steering, braking assistance, and air conditioning systems remain active. In
certain situations it may be necessary for the system to start the combustion engine even when the
vehicle is not moving. With prolonged driving in traffic jams, the combustion engine will be switched on
and off to charge the high-voltage battery for the following start-stop phase.

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 antici-
pate the vehicle's power requirements. The instrument cluster powermeter shows zero.

WARNING

Rapid acceleration can cause loss of traction and skidding, particularly on slippery roads.
This can cause you to lose control of the vehicle, which can lead to accidents and serious
injuries.

Always adjust your driving style in accordance with the flow of traffic.
Only use kickdown or fast acceleration if permitted by visibility, weather, road and traffic

conditions, and if other road users are not put at risk due to the acceleration and the driving
style.

Cooling the high-voltage battery

There are ventilation slots under the rear seat bench that provide the high-voltage battery with cool air.

The ventilation area under the rear seat bench must not be blocked or covered

⇒ .

Maintenance of the high-voltage battery

Other than taking the vehicle in for scheduled maintenance to an authorized Volkswagen dealer or an
authorized Volkswagen Service Facility that is qualified to do work on hybrid vehicles, there is nothing
that the vehicle driver has to do to maintain the high-voltage battery.

The maintenance connection for the high-voltage battery is under the luggage compartment floor
under an orange cover. This connection is only for scheduled maintenance, which must be performed
only by specially trained service technicians. There is no need to remove the connector at any time

when the vehicle is being used

⇒

WARNING

The high-voltage hybrid electrical system is dangerous and can cause burns, other serious
personal injuries, electrocution and death.

Never open, service, repair, or disconnect the high-voltage hybrid battery.
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, or battery poles have been
damaged in a crash or in some other way.

Always have work on the hybrid electrical system and on 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.

WARNING

Failure to heed warning lights and instrument cluster text messages can cause the vehicle to
break down in traffic and result in a collision and serious personal injury.

Never ignore warning lights or text WARNINGS.
Always stop the vehicle as soon as it is safe to do so.

NOTICE

Failure to heed warning lights or text WARNINGS can result in vehicle damage.
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.

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).

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.

WARNING

Driving on today's roads demands the full attention of the driver at all times. Driver distrac-
tion causes accidents, collisions and serious personal injury!

Never let yourself be distracted when setting, adjusting, or using the Infotainment System,

when using your mobile phone, or when operating the mobile phone controls.

Always drive attentively and responsibly. Use the Infotainment system, your mobile

phone, and the mobile phone controls only if road, traffic, and weather conditions permit and
you will not be distracted from your driving.

If you cannot use the Infotainment System, your mobile phone, or the mobile phone con-

trols safely while driving, wait until later or find a safe spot where you can pull off the road
and park the vehicle.

Always set sound volume levels so that you can clearly hear horns, sirens, and other

warning sounds outside the vehicle.

Setting the sound volume too high may damage your hearing. This applies even if you are

exposed to high volumes for short periods only.

Cruise control

Introduction

In this section you’ll find information about:

Indicator lights

Cruise control operation

Your vehicle may be equipped with cruise control, which helps maintain an individually stored constant
speed when driving above about 15 mph (20 km/h).

Cruise control slows down the vehicle only by reducing the flow of fuel to the engine, not by braking
⇒

More information:

Shifting
Parts, accessories, repairs, and modifications

WARNING

Using the cruise control when it is not possible to drive safely at a constant speed can be
dangerous and can lead to an accident and serious personal injuries.

Never use cruise control when driving in heavy or varying traffic or when you cannot keep

a safe distance between you and the vehicles ahead of you.

Never use cruise control on steep, winding, or slippery roads (such gravel roads, wet

roads, or snowy or icy roads) or on roads with standing water.

Never use cruise control when driving off-road or on unpaved roads.
Always adjust your speed and the distance you keep between you and the vehicles ahead

of you to the road, traffic, weather, and visibility conditions.

To help prevent unintended operation of cruise control, switch the system off when it is

not being used.

It is dangerous to use the Resume feature when the previously set speed is too high for

the existing road, traffic, or weather conditions.

When going downhill, the cruise control may not be able to maintain a constant speed.

The vehicle will speed up because of its own weight. Downshift and/or use the foot brake to
slow the vehicle.
