Fuel VOLKSWAGEN JETTA 2013 1B / 6.G User Guide

WARNING
Parking improperly can cause serious personal injury.
x Never remove the key from the ignition switch while the vehicle is moving or rolling to a
stop. The steering wheel will lock and you will not be able to steer or control the vehicle.
x Never park the vehicle where the hot exhaust system or catalytic converter could ignite
flammable materials, such as brush, leaves, dry grass, spilled fuel, etc.
x Always apply the parking brake when parking your vehicle.
x Improper use of the parking brake can seriously injure you and your passengers.
x Never use the parking brake to slow down the vehicle when it is moving, except in an
emergency. The stopping distance is much longer because only the rear wheels are braked.
Always use the foot brake to stop the vehicle.
x Never activate the throttle manually from the engine compartment when the engine is
running and the automatic transmission is in gear. The vehicle will start to move as soon as
the engine speed increases even if the parking brake is on.
x Never leave children or anyone who cannot help themselves behind in the vehicle. They
could release the parking brake and move the gear selector lever or gear shift, which could
cause the vehicle to start moving. This can lead to a crash and serious personal injuries.
x Always take the key with you when you leave the vehicle. The engine can be started and
vehicle systems such as the power windows can be operated, leading to serious personal
injury.
x Never leave children, disabled persons, or anyone who cannot help themselves in the
vehicle. The doors can be locked with the remote control vehicle key, trapping passengers in
the vehicle in an emergency. For example, depending on the time of year, people trapped in
the vehicle can be exposed to very high or very low temperatures.
x Heat build-up in the passenger and luggage compartment of a parked vehicle can result in
temperatures in the vehicle that are much higher than the outside temperatures, particularly
in summer. Temperatures can quickly reach levels that can cause unconsciousness and
death, particularly to small children.

NOTICE
x Always be careful when you park in areas with parking barriers or high curbs. These vary in
height and could damage your bumper and related parts if the front of your vehicle hits a
barrier or curb that is too high while you are getting into or out of a parking spot. To help
prevent damage, stop before the tires of your vehicle touch a parking barrier or curb.
x Always be careful when you enter a driveway or drive up or down steep ramps or over
curbs or other obstacles. Parts of the vehicle close to the ground may be damaged (such as
bumper covers, spoilers, and parts of the engine, suspension, and exhaust systems).

Saving fuel and helping the environment

Defensive driving and “flowing” with traffic
Frequent braking and acceleration increase fuel consumption significantly. Just by driving defensively
and keeping a sufficiently large distance away from the vehicle in front of you can make up for the
speed fluctuations caused by taking your foot off the accelerator. Active braking and accelerating is
then not necessarily required.
Calm and smooth driving
Consistency is more important than speed. The more smoothly you drive, the less fuel the vehicle
consumes.
When driving on the highway or freeway, a constant, moderate speed is more efficient and economical
than constantly accelerating and braking. Usually you can reach your destination just as quickly by
driving at a moderate, but steady speed.
The cruise control system can assist in maintaining a uniform driving style.
Moderate use of extra electrical loads
Comfort inside the vehicle is nice and important, but it is important to use them in an environmentally
conscious manner.
Some devices can increase fuel consumption when activated (examples):
x Climate control system (air conditioner): If the air conditioner has to produce starkly contrasting
temperatures, it requires a large amount of energy, which is generated by the engine. The temperature
in the vehicle should therefore not be extremely different from that of the outside temperature. It may
be helpful to ventilate the vehicle before driving and then to drive a short distance with the windows
open. After that, switch on the air conditioner with the windows closed. Keep the windows closed when
driving at high speeds. Open windows increase fuel consumption.
x Switch off seat heating once it has served its purpose.
x Switch off the rear window defroster as soon as the windows are free of fog and ice.
Additional factors that increase fuel consumption (examples):
x Malfunctioning engine control.
x Driving in the mountains.
x Towing a trailer.
NOTICE
Never let the vehicle coast or roll down a hill in Neutral (N), especially when the engine is not
running. The transmission will not be lubricated and will be damaged.

Fuel-efficient driving

Fig. 116 Fuel consumption in mpg at 2 different outside air temperatures.

Fig. 117 Fuel consumption in l/100 km at 2 different outside air temperatures.

Under the same conditions, the vehicle consumes more fuel in winter than in summer.
“Letting the engine run to warm up” is not only illegal in some places, but also technically not
necessary and wastes fuel.
Adjust the tire pressure
The proper tire pressure helps reduce rolling resistance as well as fuel consumption.
When purchasing new tires, always make sure that the tires are optimized for lower rolling resistance.
Use low viscosity engine oil
Fully “synthetic,” low viscosity engine oils that expressly comply with Volkswagen oil quality standards
reduce fuel consumption. Low viscosity engine oils reduce the frictional resistance on the engine and
are distributed more evenly and quickly, particularly when cold-starting the engine. The effect is
particularly apparent in vehicles that frequently travel short distances.
Always ensure the right engine oil level is maintained and keep to the scheduled service intervals
(engine oil changes).
Make sure the engine oil that you purchase expressly complies with Volkswagen oil quality standards
and is the oil approved by Volkswagen for your vehicle.
Avoid unnecessary weight
The lighter the vehicle, the more economical and eco-friendly it will be. For example, an extra 220 lbs
(100 kg) of weight increases fuel consumption by up to 1 pint per 60 miles (0.3 l/100 km).
Remove all unnecessary items and unnecessary dead weight from the vehicle.
Remove unnecessary aftermarket components
The more aerodynamic the vehicle, the less fuel it will consume. Aftermarket components such as
bicycle racks reduce its aerodynamic performance.
Therefore, remove unnecessary structures and unused rack systems, particularly if planning to drive at
higher speeds.

WARNING
Incorrect tire pressures and/or underinflation can cause sudden tire failure, loss of control,
collision, serious personal injury or even death.
x When the warning symbol appears in the instrument cluster, stop and inspect the tires.
x Incorrect tire pressure and/or underinflation can cause increased tire wear and can affect
the handling of the vehicle and stopping ability.
x Incorrect tire pressures and/or underinflation can also lead to sudden tire failure,
including a blowout and sudden deflation, causing loss of vehicle control.
x The driver is responsible for the correct tire pressures for all tires on the vehicle. The
recommended tire pressure values are listed on a sticker inside the driver door .
x The TPMS can only work correctly when all tires on the vehicle are filled to the correct
cold tire inflation pressure.
x Using incorrect tire pressure values can cause accidents or other damage. Always inflate
the tires to the correct specified cold tire pressure values for the tires installed on the vehicle.
x Always maintain correct cold tire inflation pressure so that TPMS can do its job.
x Always inflate tires to the recommended and correct tire pressure before driving off.
x Driving with underinflated tires causes them to flex (bend) more, letting them get too hot,
resulting in tread separation, sudden tire failure, and loss of control.
x Excessive speed and/overloading can cause heat build-up, sudden tire failure and loss of
control.
x If the tire pressure is too low or too high, the tires will wear prematurely and the vehicle
will not handle well.
x If the tire is not “flat” and you do not have to change a wheel immediately, drive carefully
and at reduced speed to the nearest service station to check the tire pressure and add air as
required.
x When replacing tires or wheel rims on vehicles equipped with TPMS always read and heed
the information and all WARNINGS regarding , Tires and wheels.
x The Tire Pressure Monitoring System must be recalibrated using the SET button whenever
you remove and remount or change any wheel or tire on the vehicle, even if the reinstalled or
replacement wheels and tires are identical to those that were removed and even if the tire
pressure does not change .

WARNING
Improper use of the SET button can cause the TPMS to give false warnings or to give no
warning despite dangerously low tire pressure .
Underinflation increases fuel consumption and tire wear.
Do not rely solely on the Tire Pressure Monitoring System. Check your tires regularly to make
sure they are properly inflated and have no signs of damage, such as punctures, cuts, cracks, and
blisters. Remove any objects that become embedded in the tire tread but have not penetrated into the
body of tire itself.

Refueling

WARNING
Even if empty, portable fuel containers can leak and cause a fire and serious personal
injuries, especially in a crash.
x For your safety, we strongly recommend that you do not travel with a portable fuel
container in your vehicle.
x If, under exceptional circumstances, you must transport a portable fuel container, please
observe the following:
– Never fill a portable fuel container while it is anywhere in or on the vehicle (for
example, in the luggage compartment or on top of the luggage compartment lid). Static
electricity can build up while filling and can ignite fuel vapors, causing a fire.
– Always place a portable fuel container on the ground before filling. Never spill fuel
inside the vehicle or luggage compartment. Fuel vapors are highly flammable.
– Always keep the filler nozzle completely inside the portable container before and
during filling.
– If filling a portable container made of metal, the filler nozzle must always be in contact
with the container. This will help prevent static electricity from discharging and causing a
fire.
– Always observe local and state or provincial laws about the use, storage, and
transportation of portable fuel containers.
– Make certain that the portable fuel container meets industry standards, such as
ANSI/ASTM F852-86.

NOTICE
x Remove fuel spills from the vehicle immediately to help prevent damage to the paint, tires,
and wheel housings.
x Refueling with gasoline when your vehicle has a diesel engine or refueling with diesel fuel
when your vehicle has a gasoline engine can cause very serious and expensive engine and
fuel system damage that is not covered by any Volkswagen Limited Warranty.
x If you put any amount of incorrect fuel in the fuel tank, do not start the engine under any
circumstances. Immediately contact the nearest authorized Volkswagen dealer or authorized
Volkswagen Service Facility for assistance. These fuels contain substances that can severely
damage the fuel system and the engine if the engine is started.
x Vehicles with diesel engines must never be refueled or driven with gasoline, kerosene,
heating oil, or other non-specified fuels that have not been expressly approved for use with the
diesel engine. Other kinds of fuel can cause serious damage to the fuel system and the engine
that is not covered by any Volkswagen Limited Warranty.
Fuels can pollute the environment. Spilled fuel must be collected and disposed of properly,
following all applicable environmental regulations.
There is no emergency release for the fuel filler flap. Contact an authorized Volkswagen dealer or
an authorized Volkswagen Service Facility for assistance.

Indicator lights and fuel gauge

WARNING
Driving with a fuel tank that is almost empty can lead to stalling in traffic, a collision, and
serious personal injuries.
x When the fuel tank is almost empty, fuel supply to the engine can be interrupted,
especially when driving over bumps, across slopes, and up and down hills.
x Steering and braking assistance as well as ESC and related systems will not work if the
engine “sputters” or stalls due to lack of fuel.
x Always refuel when the tank is 1/4 full to reduce the risk of running out of fuel and stalling
in traffic.

NOTICE
x Failure to heed warning lights or text WARNINGS can result in vehicle damage.
x Never drive until the fuel tank is completely empty. The irregular fuel supply can cause the
engine to misfire. This allows unburned fuel to get into the exhaust system and damage the
catalytic converter or the diesel particulate filter.
The small arrow next to the gas pump symbol in the fuel gauge shows the side of the vehicle with
the fuel filler flap.
