2013 VOLKSWAGEN PASSAT warning light

x The system must be recalibrated using the SET button whenever you remove and remount or
change any wheel or tire on the vehicle, even if the reinstalled or replacement wheels and tires are
identical to those that were removed and even if the tire pressure does not change.
x If you have to adjust the tire pressure on a warm tire, fill the tire with 2.0 - 4.35 psi (20 - 30 kPa)
more than the pressure specified on the tire pressure label inside the fuel filler flap inside the driver
door.
x If the TPMS determines that the air pressure in at least one tire is too low, carefully check the
pressure in all 4 tires with an accurate tire pressure gauge. Low tire pressure usually cannot be
determined by looking at the tire. This is especially true of low-profile tires.
If you have work done on your wheels or tires, inform the workshop that the vehicle is equipped
with a Tire Pressure Monitoring System (TPMS).
New tires may expand slightly the first time they are driven at high speeds, which can trigger a
tire pressure warning. Remember that tire pressure can only be properly measured when the tire is
“cold”.
Only replace old tires with tires that have been approved by Volkswagen for your vehicle type.
Indicator light (telltale)

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
Incorrect tire pressures and/or underinflation can cause sudden tire failure, loss of control,
collision, serious personal injury, or even death.
x When the warning symbol

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.
NOTICE
Failure to heed warning lights or text WARNINGS can result in vehicle damage.
If the ignition is switched on, an acoustic warning sounds when low tire pressure is detected. If a
system malfunction is detected, no acoustic warning sounds.
Driving for a longer period of time on rough roads or with a dynamic and sporty style can make
the TPMS system temporarily unavailable. The indicator light will come on, signaling a malfunction, but
will go out again once the road condition or driving style changes.
Applicable only in Canada and the United States

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 heating and ventilation systems 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 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 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 AC button. The indicator light in the button must come on.
When it is very hot and humid outside, water condensation can drip from the air conditioner
evaporator and form a puddle under the vehicle. This is normal and does not indicate a leak.
Keep the air intake slots in front of the windshield free of ice, snow and leaves in order to
maintain proper functioning of the heating and ventilation systems.
Maximum heating output and defrosting performance are not possible until the engine has
reached operating temperature.

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

Automatic air recirculation <
In the < setting, fresh air enters the passenger compartment. If the system detects an increased
concentration of pollutants in the outside air, it automatically switches to air recirculation. As soon as
the pollutant level is back in the normal range, air recirculation is switched off.
Unpleasant odors cannot be detected by the system.
Air recirculation is not automatically activated under the following outside temperatures and
conditions:
x The outside air temperature is colder than about +38 °F (+3 °C).
x The cooling system and the windshield wiper are switched off and the outside air temperature is
cooler than about +50 °F (+10 °C).
x The cooling system is switched off, the outside air temperature is cooler than about +59 °F
(+15 °C), and the windshield wiper is switched on.
Switching automatic air recirculation on and off
Switching on: Press the  button repeatedly until the right indicator light under the button comes on.
Switching off: Press the  button repeatedly until no indicator light under the button is on.
It is not possible to activate automatic air recirculation when the outside air temperature is colder than
about +38 °F (+3 °C).
Temporarily deactivating automatic air recirculation
x Press the  button once to switch to air recirculation temporarily in the event of unpleasant odors.
The left indicator light comes on.
x Press the  button again after more than 2 seconds to resume automatic air recirculation. The
right indicator light comes on.
WARNING
Stale air causes driver fatigue and reduces driver alertness, which can cause accidents,
collisions and serious personal injury.
x Never use air recirculation mode over an extended period of time, since no fresh air will
enter the passenger compartment.
x 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.
NOTICE
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.
Climatronic: When backing up and while the automatic wiper/washer is working, air recirculation
is briefly activated to help keep exhaust fumes from getting into the passenger compartment.

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.

slightly with light pressure to open the misfueling guard. If the misfueling guard cannot be opened this
way, see the nearest authorized Volkswagen dealer or authorized Volkswagen Service Facility and
have the fuel system checked.
WARNING
Spilled fuel can cause fires, explosions, burns, and other severe injuries.
x Do not refuel from devices other than correct, undamaged standard diesel fuel pump
nozzles.
x Always stop refueling once the pump nozzle switches off so that the tank does not
overflow.
NOTICE
x It is your responsibility to put the right fuel in your vehicle and any damage that results is
not covered under the Emissions warranties or any other 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 Never force a fuel nozzle in the misfueling guard. If you have problems inserting a fuel
nozzle, first check to make sure you are using the correct diesel fuel. If you are, go to a pump
with the standard diesel nozzle. Forcing a fuel nozzle in the misfueling guard can damage it so
that it can no longer help prevent misfueling.
