2014 VOLKSWAGEN CC fuel consumption

When replacing tires or wheel rims on vehicles equipped with
TPMS always read and heed the information and all WARNINGS
regarding tires and wheels ⇒  Tires and wheels.
NOTICE
The wheel electronics are attached to special aluminum valves
on the wheels. These valves are screwed on rigidly. Never bend
the valves “into position” when checking and adjusting tire
pressure.
Missing valve stem caps can cause damage to the valves as
well as to the TPMS sensors. To help prevent damage, always
use valve stem caps like those originally installed at the factory.
The caps must be screwed on tightly. Do not use metal valve
stem caps.
Do not use “comfort valve caps.” They do not seal properly
and can damage the sensors.
When replacing or rotating tires, make certain the valves and
sensors are not damaged.
The aluminum valves that are installed should be replaced
after about 6 years of use because of aging in the rubber seals.
The valves can be replaced when a tire is changed. Do not reuse
aluminum valves after they are removed. They must be replaced.
The tire pressure sensor can be reused.
When replacing the valve cores, use only nickel-plated re-
placement cores.
The batteries in the wheel electronics last up to 10 years. It is
not possible to replace the batteries. The entire device must be
replaced.
Underinflation increases fuel consumption and tire wear.
Dispose of the wheel electronics and the old batteries in an envi-
ronmentally responsible manner. Batteries of the type used in the
wheel electronics may contain Perchlorate Material. Special handling
may apply. See www.dtsc.ca.gov/hadardouswaste/perchlorate. Obey
all applicable legal requirements regarding proper disposal.

Vehicles with gear recommendation aid in fuel efficient driving by in-
dicating the optimum time to shift gears.
Coasting
If you take your foot off the accelerator, fuel delivery to the engine is
interrupted, which lowers fuel consumption.
Therefore, when nearing a red stop light, for instance, allow the vehi-
cle to coast without using the accelerator. Press the clutch pedal and
release it only if the vehicle moving too slowly or the coasting dis-
tance is too long. The engine will then continue to run at idle.
In situations where the vehicle will be stopped for a longer period of
time, such as at a railroad crossing, physically switch off the engine.
Defensive driving and “flowing” with traffic
Frequent braking and acceleration increase fuel consumption signifi-
cantly. 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. Ac-
tive 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 (exam-
ples):
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. Af-
ter that, switch on the air conditioner with the windows closed. Keep
the windows closed when driving at high speeds. Open windows in-
crease fuel consumption.
Switch off seat heating once it has served its purpose.
Switch off the rear window defroster as soon as the windows are
free of fog and ice.
Additional factors that increase fuel consumption (examples):
Malfunctioning engine control.
Driving in the mountains.
Towing a trailer.
NOTICE
Never let the vehicle coast or roll down a hill in Neutral (N), es-
pecially when the engine is not running. The transmission will
not be lubricated and will be damaged.

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 opti-
mized 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 vis-
cosity 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. Af-
termarket 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.

As long as the indicator lights B or %0# are on, expect engine mal-
functions, increased fuel consumption, and loss of engine efficiency.
