Maintenance Procedures -> Exhaust System for Your Volkswagen Routan SUV First Generation (2009-2014)

Exhaust System  
WARNING!  
The best protection against carbon monoxide entry into  
the vehicle body is a properly maintained engine exhaust  
system.  
The air induction system (air cleaner, hoses, etc.) can  
provide a measure of protection in the case of engine  
backfire. Do not remove the air induction system (air  
cleaner, hoses, etc.) unless such removal is necessary  
for repair or maintenance. Make sure that no one is  
near the engine compartment before starting the  
vehicle with the air induction system (air cleaner,  
hoses, etc.) removed. Failure to do so can result in  
serious personal injury.  
If you notice a change in the sound of the exhaust system;  
or if the exhaust fumes can be detected inside the vehicle;  
or when the underside or rear of the vehicle is damaged;  
have an authorized technician inspect the complete ex-  
haust system and adjacent body areas for broken, dam-  
aged, deteriorated, or mispositioned parts. Open seams  
or loose connections could permit exhaust fumes to seep  
into the passenger compartment. In addition, inspect the  
exhaust system each time the vehicle is raised for lubri-  
cation or oil change. Replace as required.  
Engine Air Filter Selection  
The quality of replacement engine air filters varies con-  
siderably. Only high quality filters should be used to  
assure most efficient service. Volkswagen Genuine Parts,  
like the air filter, are recommended due to their high  
quality.

Under normal operating conditions, the catalytic con-  
verter will not require maintenance. However, it is im-  
portant to keep the engine properly tuned to assure  
proper catalyst operation and prevent possible catalyst  
damage.  
WARNING!  
Exhaust gases can injure or kill. They contain carbon  
monoxide (CO), which is colorless and odorless.  
Breathing it can make you unconscious and can  
eventually poison you. To avoid breathing CO, refer  
to “Safety Tips/Exhaust Gas” in “Things To Know  
Before Starting Your Vehicle” for further informa-  
tion.  
CAUTION!  
Damage to the catalytic converter can result if your  
vehicle is not kept in proper operating condition. In  
the event of engine malfunction, particularly involv-  
ing engine misfire or other apparent loss of perfor-  
mance, have your vehicle serviced promptly. Contin-  
ued operation of your vehicle with a severe  
malfunction could cause the converter to overheat,  
resulting in possible damage to the converter and  
vehicle.  
CAUTION!  
The catalytic converter requires the use of unleaded  
fuel only. Leaded gasoline will destroy the effective-  
ness of the catalyst as an emissions control device  
and may seriously reduce engine performance and  
cause serious damage to the engine.

NOTE: Intentional tampering with emissions control To minimize the possibility of catalytic converter dam-  
systems can result in civil penalties being assessed age:  
against you.  
Do not shut off the engine or interrupt the ignition,  
when the transmission is in gear and the vehicle is in  
motion.  
WARNING!  
A hot exhaust system can start a fire if you park over  
materials that can burn. Such materials might be  
grass or leaves coming into contact with your exhaust  
system. Do not park or operate your vehicle in areas  
where your exhaust system can contact anything that  
can burn.  
Do not try to start the engine by pushing or towing the  
vehicle.  
Do not idle the engine with any spark plug wires  
disconnected or removed, such as when diagnostic  
testing, or for prolonged periods during very rough  
idle or malfunctioning operating conditions.  
In unusual situations involving grossly malfunctioning  
engine operation, a scorching odor may suggest severe  
and abnormal catalyst overheating. If this occurs, stop  
the vehicle, turn off the engine and allow it to cool.  
Service, including a tune-up to manufacturer’s specifica-  
tions, should be obtained immediately.  
Maintenance-Free Battery  
Your vehicle is equipped with a maintenance-free battery.  
You will never have to add water, nor is periodic main-  
tenance required.

WARNING!  
CAUTION!  
Battery fluid is a corrosive acid solution and can  
burn or even blind you. Do not allow battery fluid  
to contact your eyes, skin, or clothing. Do not lean  
over a battery when attaching clamps. If acid  
splashes in eyes or on skin, flush the area imme-  
diately with large amounts of water.  
It is essential when replacing the cables on the  
battery that the positive cable is attached to the  
positive post and the negative cable is attached to  
the negative post. Battery posts are marked posi-  
tive (+) and negative (-) and are identified on the  
battery case. Cable clamps should be tight on the  
terminal posts and free of corrosion.  
Battery gas is flammable and explosive. Keep  
flame or sparks away from the battery. Do not use  
a booster battery or any other booster source with  
an output greater than 12 Volts. Do not allow cable  
clamps to touch each other.  
If a “fast charger” is used while the battery is in  
the vehicle, disconnect both vehicle battery cables  
before connecting the charger to the battery. Do  
not use a “fast charger” to provide starting voltage.  
Battery posts, terminals, and related accessories  
contain lead and lead compounds. Wash hands  
after handling.
