Anti-Lock Brake System (ABS)
ABS helps to keep the wheels from locking up and helps to maintain the driver's ability to steer and
control the vehicle. This means the vehicle is less likely to skid, even during hard braking:
x Push the brake pedal down hard and hold it there. Don't take your foot off the pedal or reduce the
force on the pedal!
x Do not “pump” the brake pedal or let up on it!
x Steer the vehicle while pushing down hard on the brake pedal.
x ABS stops working if you release or let up on the brake.
When ABS is doing its job, you will notice a slight vibration through the brake pedal and hear a
noise. ABS cannot shorten the stopping distance under all conditions. The stopping distance may
even be longer, for instance, when driving on gravel or on newly fallen snow covering an icy or
slippery surface.
Brake Assist (BAS)
The Brake Assist System can help to reduce stopping distances. If you press the brake pedal very
quickly, BAS detects an emergency situation. It then very quickly builds up full brake system pressure,
maximizing braking power and reducing the stopping distance. This way, ABS can be activated more
quickly and efficiently.
Do not reduce pressure on the brake pedal! BAS switches off automatically as soon as you release or
let up on the brake.
Anti-Slip Regulation (ASR)
ASR reduces engine power directed to spinning wheels and adjusts power to the road conditions.
Even under poor road conditions, ASR can make it easier to get moving, accelerate, and climb hills.
ESC and ASR can help when driving on loose surfaces (such as gravel) and in deep snow. If you get
stuck in deep snow, you may be able to get going again by “rocking” the vehicle back and forth. ESC
and ASR recognize this special driving situation and automatically increase the speed of the front
wheels. Keep pressing the accelerator and let ESC increase the speed of the front wheels to help you
keep moving or get moving again.
Electronic Differential Lock (EDL and XDL)
EDL is applied during regular straight-line acceleration. EDL gently brakes a drive wheel that has lost
traction (spinning) and redirects the drive force to other drive wheels. In extreme cases, EDL
automatically switches off to keep the brake from overheating. As soon as the brake has cooled down,
EDL automatically switches on again.
XDL is an extension of the Electronic Differential Lock system. XDL does not react to drive wheel
slippage when driving straight ahead. Instead, XDL detects slippage of the inside front wheel during
fast cornering. XDL applies enough brake pressure to this wheel in order to stop the slippage. This
improves traction, which helps the vehicle stay on track.

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.

WARNING
Poor visibility increases the risk of collisions and other accidents that cause serious
personal injuries.
x Always make sure all windows are clear of ice, snow and condensation for good visibility
to the front, sides, and rear.
x Maximum heating output and defrosting performance are not possible until the engine has
reached operating temperature. Wait until you have good visibility before driving off.
x Always make sure you know how to properly use the climate control system as well as the
rear window defroster that you will need for good visibility.
x Never use air recirculation for long periods of time. When the air conditioner is off and
recirculation mode is on, condensation can quickly form on the windows and greatly reduce
visibility.
x Always switch off recirculation mode when it is not needed.

WARNING
Stale air causes driver fatigue and reduces driver alertness, which can cause accidents,
collisions and serious personal injury.
x Never switch off the fan for a long period of time and never use air recirculation for a long
period of time because no fresh air will enter the passenger compartment.

NOTICE
x If you think the air conditioner is not working properly or may be damaged, switch it off to
help prevent more damage. Have the air conditioner checked by an authorized Volkswagen
dealer or an authorized Volkswagen Service Facility.
x Air conditioner repair requires specialized knowledge and special tools. Volkswagen
recommends that you see an authorized Volkswagen dealer or an authorized Volkswagen
Service Facility.
x Do not smoke when air recirculation is switched on. Smoke drawn into the ventilation
system can leave residue on the evaporator and on the dust and pollen active carbon filter,
resulting in permanent odors whenever the air conditioner is switched on.
If the air conditioner is switched off, the fresh outside air will not be dehumidified. To help keep
the windows from fogging over, Volkswagen recommends leaving the air conditioner (compressor)
switched on. Press the!

Maximum heating output and defrosting performance are not possible until the engine has
reached operating temperature.
Emergency starting and starting the engine with a very weak vehicle battery or after the vehicle
battery has been replaced may change or delete system settings (including time, date, personal
convenience settings, and programming). Check the settings and correct as necessary once the
vehicle battery has built up a sufficient charge.

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.

Winter diesel
At temperatures below 20 °F (-7 °C), wax separation in ULSD occurs. Wax may clog the fuel filter or
tank filter and keep the engine from running.
To help prevent the filter from being clogged with wax, the fuel filter in your vehicle is heated with
warm fuel when the engine is running (filter preheating system). Heating the fuel filter makes it
possible to use your vehicle with ULSD down to about -10 °F (-24 °C).
If you expect temperatures below +5 °F (-15 °C) ask your fuel dealer if their ULSD is sufficiently
winterized.
If non-winterized or insufficiently winterized diesel fuel has already thickened to the point that the
engine will not start, move the vehicle to a heated garage or workshop until it has warmed up.
Cold diesel engines normally produce louder noises during winter conditions than during warmer
periods. In addition, the exhaust gases may be light blue in color until the engine has warmed up. The
exhaust gas volume varies depending on the outside temperature.
Do not let your diesel engine idle unnecessarily after a cold start. Driving off slowly will shorten the
warm-up period.
WARNING
Starting fluids can explode and cause a run-away vehicle condition.
x Never use starting assist fluids.

NOTICE
x The vehicle's diesel engine was designed solely for use with ULSD fuel. For this reason,
never use gasoline, heating oil, or other fuels that have not been expressly approved for use
with the diesel engine. These fuels contain substances that will severely damage the fuel
system and the engine. Such damage will not be covered by any Volkswagen Limited Warranty.
x If you put any amount of the 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.
x If diesel fuel should get on any rubber hose, it must be wiped off immediately. The same
applies if diesel fuel gets onto other parts of the vehicle, especially paint, tires, or a plastic
part. Wash the contaminated vehicle parts right away with soap and warm water to help
prevent leaks and serious damage.
x The vehicle is designed to run on diesel fuel containing methyl ester biodiesel in
concentrations of 5% or less. Never use methyl ester biodiesel in blend levels higher than 5%
(5%/ methyl ester blends are sometimes designated or labeled as B5). The properties of methyl
ester biodiesel blends in levels greater than 5% may cause serious damage to the fuel injection
system and to the engine. This could lead to expensive repairs that will not be covered by any
Volkswagen Limited Warranty.
x Damage to the engine and fuel system and performance problems caused by using fuels
that are different from those specified above or by using “starting assist fluids” are not the
responsibility of Volkswagen and are not covered under the Emission warranties or any other
Volkswagen Limited Warranty.
