When the ignition is switched on, several warning and indicator lights come on briefly for a function
check. They go out after a few seconds.
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.
x Never ignore warning lights or text WARNINGS.
x Always stop the vehicle as soon as it is safe to do so.
x Whenever stalled or stopped for repair, move the vehicle a safe distance off the road, stop
the engine, turn on the emergency flashers, and use other warning devices to warn
approaching traffic.
x Never park the vehicle in areas where the hot catalytic converter and exhaust system can
come into contact with dry grass, brush, spilled fuel, oil, or other material that can catch fire.
x A broken down vehicle presents a high accident risk for itself and others. Switch on
emergency flashers and set up a warning triangle to warn oncoming traffic.
NOTICE
Failure to heed warning lights or text WARNINGS can result in vehicle damage.
High Intensity Discharge (HID) headlights provide bright, uniform lighting to help you see and be
seen. The light comes from an electric arc between two electrodes in the gas-filled bulb. Over time, the
electrodes can wear down and the gap between them will get wider. The HID lamp’s control unit then
increases the voltage to keep the arc’s brightness constant. However, the commonly called “Xenon”
bulbs will also ultimately burn out. Before they burn out, HID lamps can flicker. A message will then
appear in the MFI. This is your reminder to see an authorized Volkswagen dealer or an authorized
Volkswagen Service facility to check the headlights.

WARNING
To reduce the risk of serious personal injury when starting and running the vehicle's engine:
x Never start the engine or let it run in a confined or enclosed area. Engine exhaust contains
carbon monoxide, a poisonous, colorless, and odorless gas. Carbon monoxide can cause
unconsciousness and death.
x Never leave the vehicle unattended with the engine running. The vehicle could move
suddenly or some other unexpected event could occur, resulting in property damage or
personal injury.
x Never use starting assist fluids. Starting fluids can explode and can cause a “run-away”
vehicle condition.
WARNING
The vehicle exhaust system and the catalytic converter or diesel particulate filter get very hot.
They can cause fires and serious personal injury.
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 Never apply additional undercoating or rust proofing on or near the exhaust manifold,
exhaust pipes, catalytic converter, diesel particulate filter, or heat shields.

WARNING
Never leave the vehicle unattended while the engine is running. The vehicle could move
suddenly, especially when the vehicle is in gear, resulting in accidents and personal injury.
WARNING
“Starting fluids” can explode and can cause a “run-away” vehicle condition.
x Never use starting assist fluids.
NOTICE
x You can damage the starter or the engine if you try to start the engine when the vehicle is
still moving, or if you try to restart the engine right after switching it off.
x Avoid high engine speeds, full throttle acceleration, and heavy engine loads when the
engine is cold.
x Do not try to start the engine by pushing or towing the vehicle. Unburned fuel can get into
the catalytic converter and damage it. The steering column may also be locked.
Do not let your vehicle warm up while standing; instead, start driving right away after making sure
that you have good visibility through all windows. This will help the engine reach operating
temperature faster and keep down emissions.
Major consumers of electricity are temporarily switched off when the engine is being started.
After starting a cold engine, there may be increased operating noises for a few seconds. This is
normal and harmless.
When outside temperatures are below +41 °F (+5 °C) and the diesel fueled preheater is
activated, minor fume build-up may occur underneath the vehicle.

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).
Warning and indicator lights

x Make sure all passengers and especially children leave the vehicle.
x Take all vehicle keys with you when leaving your vehicle.
x Lock the vehicle.
On hills
Before stopping the engine, turn the steering wheel so that, if the vehicle starts to roll, its front wheels
will roll into the curb:
x Facing downhill, turn the front wheels so that they point toward the curb.
x Facing uphill, turn the front wheels so that they point away from the curb.
WARNING
The vehicle exhaust system and the catalytic converter or diesel particulate filter get very hot.
They can cause fires and serious personal injury.
x Never park where the hot exhaust system could ignite flammable materials, such as
brush, leaves, dry grass, spilled fuel, etc.

About the brakes

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.

that do not contain metal. The additives provide corrosion protection, clean the fuel system, and
prevent deposits on the engine.
Volkswagen recommends TOP TIER Detergent Gasoline. For more information on TOP TIER
Detergent Gasoline, please go to the official Web site http://www.toptiergas.com.
If quality gasoline with additives that do not contain metal is not available or engine malfunctions
occur, you should add the required additives while refueling ⇒ .
Not all gasoline additives are effective. Using the wrong additives can cause significant and expensive
damage to the engine and the catalytic converter. Never use additives that contain metal. Please note
that metal can be included in some aftermarket gasoline additives that are available to be added to
gasoline during or after refueling to help improve knock resistance or increase the octane rating.
Volkswagen recommends using only additives approved by Volkswagen. Appropriate additives as well
as instructions on how to use them are available from your authorized Volkswagen dealer or
authorized Volkswagen Service Facility. Do not add any other gasoline additives.
NOTICE
You can damage the engine by using incorrect additives.
x Using incorrect gasoline additives can cause extensive engine damage as well as damage
to the catalytic converter.
x If you must fuel your vehicle with gasoline whose octane rating is too low, only drive with
the engine speed in the middle of the rpm range and with low engine load. Avoid high rpm and
heavy engine load. Otherwise, the engine could be damaged. Refuel your vehicle with gasoline
with the required octane rating as soon as possible.
x Do not use fuel that is labeled at the pump as containing metal. Lead replacement fuel
contains high concentrations of metallic additives. Engine damage could result.
x Fueling your vehicle just one time with leaded fuel or fuel that contains other metallic
additives can affect the performance of the catalytic converter and cause extensive damage to
it.
Diesel fuel

The catalytic converter provides exhaust gas after-treatment to help reduce pollutants in the exhaust
gas. To help ensure long service life of the exhaust system and gasoline engine catalytic converter:
x Only use unleaded fuel.
x Never completely empty the fuel tank.
x Do not exceed the correct oil level
x Do not tow the vehicle to start it, but use a jump-start instead
If you experience misfires, loss of power or the engine is not running smoothly while driving, reduce
speed immediately and have the vehicle checked by an authorized Volkswagen dealer or authorized
Volkswagen Service Facility. Otherwise, gasoline could reach the exhaust system and get into the
atmosphere. The catalytic converter could also be damaged by overheating!
Under certain engine conditions, you may smell a sulfur odor. This is not an indication of a
malfunctioning emission control system. This depends upon the sulfur content of the diesel fuel.
