2018 VOLKSWAGEN CC warning lights

If the indicator in the engine coolant temperature gauge is located in
the cold range (A), the engine has not reached operating tempera-
ture. High engine speeds and heavy engine loads should be avoided.
Under normal driving conditions, the needle should be in the middle
of the gauge. The temperature may go higher when the engine is
working hard, especially in hot weather.
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.
The following table explains what to do if the engine coolant tempera-
ture warning light ~ does not go out a few seconds after the engine
is started or starts flashing while driving.

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 mes-
sages can cause the vehicle to break down in traffic and result
in a collision and serious personal injury.
Never ignore warning lights or text WARNINGS.
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.
Engine coolant specifications

Automatic electrical load deactivation
If the vehicle battery drain is high, the intelligent onboard electrical
system management automatically takes steps to help prevent bat-
tery drain.
The idle speed is increased so that the alternator provides more
power.
The power to devices that consume a lot of electricity is cut back or
switched off completely.
When the engine is started, the power supply to the 12 Volt sockets
is temporarily interrupted.
The onboard electrical system management cannot always keep the
battery from being drained. For example, the battery will drain if the
engine is not running, but the ignition is switched on or the parking
lights are left on for a long time when parked.
Battery disconnection in an accident with airbag deployment
In vehicles with a battery in the luggage compartment, the electrical
connection to the battery is disconnected automatically in a collision
with airbag deployment. This helps to prevent a short-circuit.
What drains the vehicle battery?
Long periods when the engine is not running, especially when the
ignition is on.
Using electrical systems or devices when the engine is switched
off.
Leaving the vehicle unlocked for several days when not in use.
The selector lever is left for a long period of time in any position
other than P when the ignition is switched off ⇒  Automatic transmis-
sion: Selector lever.
WARNING
Failure to use the proper battery with proper mounting and
connections may cause short circuits, fires, and serious per-
sonal injuries.
Always use only maintenance-free or cycle-free, leak-proof
batteries with the same specifications and dimensions as the
original equipment battery. Specifications are listed on the bat-
tery housing.

Rinse the sponge or glove thoroughly and often.
Clean the wheels and under the door sills last. Use a different sponge
or wash mitt.
WARNING
After the vehicle has been washed, the wet brakes or, in winter,
brake discs or pads coated with ice, react slower and need
longer stopping distances.
Always dry the brakes and clean off any ice coatings with a
few careful applications of the brake. Make sure not to endan-
ger other motorists or cyclists or disobey legal requirements.
CAUTION
Sharp edges under the vehicle can cut exposed skin.
Always protect your hands and arms from cuts on sharp
metal edges when cleaning the underbody, the inside of the
wheel housings, etc.
NOTICE
The water temperature must not be more than +140 °F
(+60 °C).
To help prevent damage to the paint, do not wash the vehicle
in direct sunlight.
Do not use insect sponges, abrasive kitchen sponges or simi-
lar things to clean the vehicle. These can damage the paint fin-
ish.
Never clean headlights with a dry cloth or sponge. Always use
a wet cloth or sponge. For best results use soapy water.
When washing or rinsing the vehicle in cold weather, do not
let water get into the lock cylinders or point the hose at gaps
around the doors, hood, or luggage compartment lid. The water
could freeze on the locks and seals and make it difficult to open
the vehicle!

WARNING
Using the wrong fuse, using a blown fuse that has been re-
paired, and using metal objects in place of fuses to complete
the electrical connection in the circuit can cause fires and seri-
ous personal injury.
Never replace a fuse with one that has a higher amp rating.
Replace a blown fuse only with a fuse of the same amperage
(same color and same imprint) and same overall size.
Never repair fuses.
Never replace fuses with a metal strip, a paper clip, or a simi-
lar object.
NOTICE
To help prevent damage to the electrical system, switch off all
lights and accessories, switch off the ignition, and remove the
key from the ignition switch before replacing a fuse.
If a fuse is replaced with a fuse with higher amperage, this can
also cause damage at different locations in the electrical system.
Open fuse boxes must be protected from dirt and moisture.
Dirt and moisture in fuse boxes can cause damage to the electri-
cal system.

WARNING
Improper replacement of burned out headlights and other light
bulbs can cause serious personal injury.
Stop! Always read and heed the WARNINGS before doing any
work in the engine compartment ⇒  Working in the engine com-
partment. The engine compartment of any motor vehicle is a
potentially dangerous area, and work in this area can lead to
serious personal injury.
HID – High Intensity Discharge (Xenon) headlights get power
from a high voltage source that can cause severe personal inju-
ry and even death if handled improperly.
H7 bulbs and HID – High Intensity Discharge (Xenon) head-
lights are under high pressure and can explode if handled im-
properly.
Always let a burned out light bulb cool down before replacing
it.
Never replace a light bulb unless you are familiar with all of
the necessary procedures. In particular, never remove a head-
light unless you know exactly how to carry out the job and have
the correct tools and light bulbs.
If you are uncertain about what to do, have the work per-
formed by an authorized Volkswagen dealer, an authorized
Volkswagen Service Facility, or another qualified workshop.
Serious personal injury may result from improperly performed
work.
We strongly recommend that you always have HID – High In-
tensity Discharge (Xenon) headlights and H7 bulbs replaced by
a qualified technician.
Do not touch the glass of light bulbs with your bare hands.
Fingerprints left on the bulb evaporate due to the heat when the
bulb is switched on and cause the reflector to “cloud.”
There are sharp edges on and around the headlight housing
in the engine compartment and the rear light housing. Wear
hand protection if you replace bulbs.

WARNING
Disregarding the safety-related checklist may lead to accidents
and serious personal injuries.
Always review and follow the checklist. Follow accepted safe-
ty practices and use common sense.
NOTICE
Always insert and remove lamps carefully to help prevent dam-
age to the vehicle paint or to other parts of the vehicle.
