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.

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.

6. If the engine does not start, switch off the ignition and start again after about 1 minute.If the engine does not start, switch off the ignition and start again after about 1 minute. Use the emergency start feature if necessary .
7. Release the parking brake when you are ready to start driving .

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.

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

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.

Fuel quality impacts the operating performance, efficiency and service life of the engine. Therefore,
use high quality gasoline that is already blended by the fuel supplier with suitable gasoline additives
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.

Checklist
For your own safety and that of your passengers, carry out the following steps in the order listed ⇒:
1. Park the vehicle at a safe distance from traffic and on a suitable surface ⇒.
2. Switch on emergency flashers by pressing the  switch ⇒fig. 147.
3. Apply the parking brake to help prevent the vehicle from moving .
4. Shift the transmission into Park (P) (automatic) or Neutral (manual only) .
5. Stop the engine and remove the key from the ignition switch .
6. Have all passengers exit and go to a safe location away from moving traffic, such as behind a
guard rail.
7. Take all vehicle keys with you when leaving your vehicle.
8. Set up a warning triangle or other warning device in order to alert other motorists and cyclists.
9. Let the engine cool down and get expert assistance if necessary.

If the emergency flashers are on, use the turn signal lever to indicate a direction or lane change, for
example when the vehicle is being towed. This temporarily interrupts the emergency flashers.
Switch on the emergency flashers when:
x Traffic suddenly slows down or stops in front of you to warn those approaching from behind.
x In any emergency situation.
x If the vehicle breaks down.
x When being towed.
Always obey traffic laws that govern the use of emergency flashers where you are driving.
If the emergency flashers are not working, a different method – as permitted by law – must be used to
alert other motorists and cyclists to the breakdown.
WARNING
Disregarding the safety-related checklist may lead to accidents and serious personal injuries.
x Always review and follow the checklist. Follow accepted safety practices and use common
sense.

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 parts of the hot exhaust system or catalytic converter could ignite
flammable materials, such as dry grass, brush, leaves, spilled fuel, etc.

WARNING
Towing a vehicle changes the way it handles and brakes. To help reduce the risk of an
accident and serious personal injury, note the following:
x The driver of the vehicle that is being towed:
– Since the brake booster also does not work when the engine is stopped, you will need
to press harder on the brake pedal to slow down or stop. Always be alert so as not to rear-
end the towing vehicle.
– Will have to use considerably more force to turn the steering wheel because the power
steering is not working.
x The driver of the vehicle that is doing the towing:
– Must accelerate gradually and gently and avoid jerking movements.
– Must not brake hard or steer sharply.
– Must brake earlier and more gently than in normal driving.

NOTICE
x Be careful not to damage the paint when installing and removing the towing eye and the
cover for the threaded hole behind the bumper.
x Unburned fuel can get into the catalytic converter during towing and damage it.
