2013 VOLKSWAGEN GOLF GTI check engine

Air conditioner does not work
The air conditioner may not switch on for one of the following reasons:
x The engine is not running.
x The fan is switched off.
x The air conditioner fuse has blown.
x The outside air temperature is colder than about +38 °F (+3 °C).
x The air conditioner compressor has been temporarily switched off due to excessive engine coolant
temperature.
x There is another malfunction in the vehicle. Have the air conditioner checked by an authorized
Volkswagen dealer or authorized Volkswagen Service Facility.
Special considerations
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.
The climate control system adjusts the passenger compartment temperature as fast as possible
considering the outside temperature.
Due to residual moisture in the air conditioner, the windshield may fog up after the engine is
started. Switch on the windshield defroster to help evaporate the condensation as quickly as possible.
The air coming out of the vents flows through the passenger compartment and through the vents
under the rear window. Do not cover these slots with clothing or other things.

Refueling
Introduction
In this section you’ll find information about:
Indicator lights and fuel gauge
Refueling
Fuel capacities
Refueling checklist
The fuel filler flap is located on the rear right side of the vehicle.
More information:
x Exterior views
x Fuel
x Preparations for working in the engine compartment
WARNING
Improper refueling or handling of fuel is dangerous and can cause fire, explosion, and severe
burns.
x Always make sure that the fuel filler cap is screwed on all the way. This helps keep fuel
from spilling out or evaporating.
x Fuel is highly flammable and explosive; it can cause severe burns and other severe
injuries.
x Failure to shut the engine off while refueling and/or to insert the pump nozzle all the way
into the fuel filler neck can cause fuel to overflow and to spray out. Fuel spray and
overflowing fuel are dangerous because they can cause fire and serious personal injury.
x During refueling, the engine and the ignition must be switched off for safety reasons.
x Never use a cellular telephone, CB radio, or other radio equipment while refueling. The
electromagnetic radiation can cause sparks that can ignite fuel vapors and cause a fire.
x Never get back into your vehicle while refueling. If in exceptional circumstances you must
get back in your vehicle while refueling, make certain that you close the door and touch metal
to discharge static electricity before touching the filler nozzle again. This helps avoid the
build-up of static electricity, which can cause sparks that can ignite fuel vapors released
during refueling.
x Never smoke or have an open flame (or sparks, cigarettes, or other smoldering objects)
anywhere in or near your vehicle when refueling or filling a portable fuel container.
x Follow all safety instructions and procedures that apply at the service station where you
refuel.
x Never spill fuel in the vehicle or the luggage compartment.

Checklist
If you are uncertain in any way, have the work done by an authorized Volkswagen dealer or
authorized Volkswagen Service Facility. Serious personal injury may result from improperly performed
work. Make sure that you check the following items regularly. The best thing is to check them every
time you refuel:
d Windshield washer fluid level
d Engine oil level
d Engine coolant level
d Brake fluid level
d Tire pressure
d Vehicle lighting necessary for driving safety:
– Turn signals
– Low beams and high beams
– Taillights
– Brake lights
– License plate lights
Information regarding changing light bulbs
WARNING
Disregarding the safety-related checklist may lead to accidents and injuries.
x Please note and follow the points listed in the checklist.

Fuel
Introduction
In this section you’ll find information about:
Gasoline
Gasoline additives
The correct fuel grade for your engine is shown on a sticker located on the inside of the fuel filler flap
⇒ fig. 147.
Bad or poor quality fuel reduces operating performance, efficiency and service life of the engine. If you
notice any symptoms like rough engine idle or performance or “bucking,” immediately reduce the
vehicle speed, accelerate slowly, and keep the engine speed in the middle of the rpm range. Avoid
high rpm and rapid acceleration. If these symptoms should appear right after refueling, switch off the
engine. In both cases contact an authorized Volkswagen dealer or an authorized Volkswagen Service
Facility to have the engine checked.

WARNING
Improper refueling or handling of fuel is dangerous and can cause fire, explosion, and severe
burns.
x Fuel is highly explosive and flammable and can cause severe burns and other injuries.
x Heed applicable safety warnings and obey local fuel handling regulations.
x Always make sure the fuel cap is screwed on all the way. This keeps fuel from spilling out
and from evaporating.
x Failure to shut the engine off while refueling and/or to insert the pump nozzle fully into the
vehicle's filler neck could cause fuel overflow and fuel spray. Fuel spray and overflowing fuel
are dangerous because they can cause fire or serious injury.
x For safety reasons, the engine must be turned off when refueling.
x Never get back into your vehicle while refueling. If in exceptional circumstances you must
get back in your vehicle while refueling, make certain that you close the door and touch metal
to discharge static electricity before touching the filler nozzle again. Static electricity can
cause sparks that can ignite fuel vapors released during refueling.
