2012 VOLKSWAGEN JETTA SPORTWAGEN fuel consumption

x If you smell an odor, immediately shut off seat heating and have it checked by an authorized
Volkswagen dealer or authorized Volkswagen Service Facility.
x Never install leather upholstery on a vehicle with seat heating that originally had cloth
upholstery. The seat heating elements for seats with cloth seats will overheat if the cloth
upholstery is replaced with leather upholstery.
Switch off seat heating when it is not needed to help reduce unnecessary fuel consumption.

WARNING
Improper use of the folding outside mirrors can cause personal injury.
x Always make sure that nobody is in the way when folding the mirrors in or out.
x Make sure that you do not get your finger caught between the mirror and the mirror base
when moving the mirrors.
WARNING
Incorrectly estimating distances with the right outside mirror can cause collisions and
serious injury.
x The right outside mirror has a convex (curved) surface. This widens your field of vision.
But vehicles or other objects seen in a convex mirror will look smaller and farther away than
they really are.
x If you use the right outside mirror to judge distances from vehicles behind you when
changing lanes, you could estimate incorrectly and cause a crash and serious injuries.
x Whenever possible, use the inside mirror to more accurately judge distance and size of
vehicles or other objects seen in the convex mirror.
x Always make sure you have a clear view to the rear of the vehicle.
NOTICE
Always fold in the outside mirrors when taking the vehicle through an automatic car wash.
To reduce fuel consumption, use outside mirror heating only when needed.
When first switched on, outside mirror heating works with maximum heat for about 2 minutes.
If power mirror adjustment does not work, the outside mirrors can be adjusted by hand by
pressing on the edges of the mirror surface.

If a roof rack is installed, fuel consumption increases due to increased air resistance.

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.

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.
When you take delivery of the vehicle, the Tire Pressure Monitoring System is calibrated for the
factory-recommended cold tire inflation pressure for the tires on your vehicle, as shown on the label
inside the driver door .
x The 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

WARNING
Driving faster than the maximum speed for which the winter tires on your vehicle were
designed can cause sudden tire failure including a blowout and sudden deflation, loss of
control, crashes and serious personal injuries.
x Winter tires have a maximum speed rating that may be lower than your vehicle's maximum
speed.
x Never drive faster than the maximum speed for which the winter tires installed on your
vehicle are rated because tires that are driven faster than their rated speed can fail suddenly.
x Never exceed the maximum load rating for the winter tires installed on your vehicle.
Install summer tires promptly in the spring. Summer tires offer better handling characteristics for
temperatures above +45 °F (+7 °C). They are quieter, do not wear as quickly, and reduce fuel
consumption.
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 or! Bookmark not defined..
If necessary, ask your authorized Volkswagen dealer or authorized Volkswagen Service Facility
about permissible winter tire dimensions.
