Cruise control system (CCS)
 Introduction
This chapter contains information on the followingsubjects:
⇒ Indicator lamp
⇒ Using the cruise control system (CCS)
The cruise control system (CCS) helps to maintain a specific preset speed during forward travel at
approx. 20 km/h (15 mph) and higher.
The CCS only slows the vehicle by easing off the accelerator, not by actively braking ⇒.

Introduction
Lit upPossible cause
Cruise control system (CCS) is controlling the speed.
Several warning and indicator lamps will light up briefly as a functional check when the ignition is
switched on. They will switch off after a few seconds.
Using the cruise control system (CCS)
The use of the cruise control system can lead to accidents and serious injuries if traffic does
not allow you to drive at a safe distance from the vehicle in front at a constant speed.
•Never use the CCS in heavy traffic, on steep or winding roads, or on slippery road
surfaces e.g. on snow, ice, wet roads, loose chippings, or on flooded roads.
•Never use the CCS when driving off-road or on unsurfaced roads.
•Adapt your speed and distance from the vehicles ahead to suit visibility, weather, road and
traffic conditions.
•Always switch cruise control off after use to avoid unintentional operation.
•It is dangerous to use a set speed that is too high for the prevailing road, traffic or weather
conditions.
•The CCS cannot maintain a constant speed when travelling downhill. The vehicle speed
can increase under its own weight. Shift down a gear or brake the vehicle using the foot
brake.
WARNING
Failure to observe the warning lamps could lead to your vehicle breaking down in traffic, and
to accidents and serious injuries.
•Never ignore any warning lamps that are lit up.
WARNING
Failure to observe the illuminated indicator lamps could lead to the vehicle being damaged.
NOTICE

If, in a potential collision scenario, the city emergency brake function detects that the driver is
applying the brakes with insufficient pressure, the system can increase the brake pressure in order
to reduce speed ahead of the collision. Hence the system can help minimise the consequences of
an accident.

The brake pedal travel decreases when the city emergency brake function is triggered. This
may make the brake pedal feel stiffer.
Automatic brake intervention by the city emergency brake function can be stopped by using
the clutch, the accelerator or steering intervention.
Unusual noises may be heard if the city emergency brake function is applying an automatic
braking procedure. This is normal and the noises are caused by the braking system.
Warning and indicator lamps
First read and observe the introductoryinformation and safety warnings⇒
Introduction
The city emergency brake function is switched on every time the ignition is switched on. No display
will be shown to alert you of this.
The indicator lamp will be lit up if the city emergency brake function is switched off, is working or if
there is a fault in the system.

The intelligent technology of the city emergency brake function cannot change the laws of
physics or the system-related vehicle limitations. Never let the extra convenience afforded by
the city emergency brake function tempt you into taking any risks when driving. The driver is
always responsible for braking in time.
•The city emergency brake function cannot prevent accidents and serious injuries by itself.
•The city emergency brake function can carry out unwanted brake interventions in certain
complex situations, e.g. if a vehicle cuts very closely in front of you.
WARNING
Incorporating the city emergency brake function into your own driving style can cause
accidents and serious injuries. The system is not a substitute for the full concentration of the
driver.
•Adapt your speed and distance from the vehicles ahead to suit visibility, weather, road and
traffic conditions.
•The city emergency brake function does not react to persons, animals and vehicles
crossing or approaching in the same lane.
•Brake the vehicle by depressing the brake if the vehicle rolls forwards once the city
emergency brake function has been applied.
WARNING
Switch off the city emergency brake function if you suspect that the laser sensor has been
damaged. This can help to prevent further damage.
•Repairs to the laser sensor require specialist knowledge. Volkswagen recommends using
a Volkswagen dealership for this purpose.

Fuels can pollute the environment. Any spilt service fluids must be cleaned up and disposed
of properly.
Indicator lamps and fuel gauge
Filling the tank incorrectly and incorrect handling of fuel can cause explosions, fire and
serious burns and injuries.
•Always ensure that the tank cap is properly closed, to prevent the evaporation and spillage
of fuel.
•Fuel is highly explosive and inflammable and can cause serious burns and other injuries.
•Fuel can spill out if the engine is not switched off or the filler nozzle is not fully inserted
into the fuel filler neck when filling the tank. This can cause fires, explosions and serious
burns and injuries.
•When filling the tank with fuel, the engine and the ignition must be switched off for safety
reasons.
•When filling the tank, always switch off your mobile telephone and two-way radio or any
other radio equipment. Electromagnetic radiation can generate sparks which can in turn
start a fire.
•Never get back into the vehicle while filling the tank. If in exceptional cases you have to
enter the vehicle, close the door and touch a metal object before touching the filler nozzle
again. This will remove any electrostatic charge from you. Failure to do so could generate
a spark. Sparks can cause a fire when filling the tank.
•Never fill the tank or fill up a spare canister near open flames, sparks or glowing matter
(e.g. cigarettes).
•Electrostatic discharge and electromagnetic radiation must be avoided when filling the
tank.
•Follow all applicable safety information provided by the filling station when filling the tank.
•Never spill fuel in the vehicle or in the luggage compartment.
WARNING
For safety reasons, Volkswagen does not recommend carrying a spare fuel canister in the
vehicle. Fuel can spill out of the full or empty canister and catch fire, especially in the event of
an accident. This could cause explosions, fire and injuries.
•If, in exceptional circumstances, you have to transport a spare fuel canister, please note
the following:
- When refilling never place the canister in or on top of the vehicle, for example in the
luggage compartment. There may be an electrostatic charge during refilling causing
the fuel fumes to ignite.
- Always place the spare fuel canister on the ground.
- When filling a spare fuel canister, place the filler nozzle as far as possible into the
filler opening.
- If the spare fuel canister is made of metal, the filler nozzle must have constant
contact with the canister in order to avoid static charging.
- Please follow all legislation concerning the use, stowage and transport of a spare
fuel canister.
- Ensure that the spare fuel canister is accordance with the industry standard, such
as ANSI or ASTM F852-86.
WARNING
•Remove spilt fuel from all vehicle components as quickly as possible in order to avoid
damage to the wheel housing, tyres and vehicle paint.
•Filling the tank with diesel in a vehicle with a petrol engine can cause serious and
expensive engine damage and cause damage to the fuel system that is not covered by any
Volkswagen guarantee. Do not start the engine under any circumstances if you have
refilled using the incorrect fuel. Seek expert assistance. The substances in these fuels can
cause serious damage to the fuel system and to the engine itself if it is switched on.

Natural gas engines
Things to note: if the vehicle is parked for an extended period directly after refuelling, it may well
occur that the pointer for the natural gas engine does not indicate the fuel level shown directly after
refuelling. This does not mean that there is a leak in the system but but rather that, for technical
reasons the pressure has been decreased in the natural gas tank.
The small arrow next to the petrol pump symbol ⇒ Fig. 115 in the display instrument shows
you the side of the vehicle on which the tank flap is located.
Only applies for vehicles with a fuel gauge in the instrument cluster ⇒ Fig. 115.

b)
Driving the vehicle when the fuel level is too low could lead to your vehicle breaking down in
traffic, accidents and serious injuries.
•When the fuel level is too low, the fuel supply to the engine could be irregular, especially
when driving up or down hills and inclines.
•The steering, all driver assist systems and brake assist systems will not function if the
engine sputters or stops completely due to a lack of fuel or irregular fuel supply.
•Always fill the tank when it is still 1/4 full. This reduces the risk of running out of fuel and
breaking down.
WARNING
•To avoid damage to your vehicle, always observe the indicator lamps and associated
warning texts.
•Do not run the tank empty. Irregular filling periods can cause backfiring and allow unburnt
fuel to enter the exhaust system. This could cause damage to the catalytic converter!
