20Using the system

WARNING■Greater physical effort is required for braking when the engine is switched
off – risk of accident!■
The clutch pedal must be actuated when braking on a vehicle with manual
transmission, when the vehicle is in gear and at low revs. Otherwise, the func-
tion of the brake booster may be impaired – risk of accident!
■
In the event of damage occurring to the standard fitted front spoiler or the
retrofitting of another front spoiler, wheel hubs etc. » page 110, Modifica-
tions, adjustments and technical alterations , It must be ensured that the air
supply to the front brake is not impaired. The front brakes may overheat,
which can have a negative impact on the functioning of the braking system –
risk of accident!
■
Never leave children unattended in the vehicle. The children might, for ex-
ample, release the handbrake or take the vehicle out of gear. The vehicle could then start to move – risk of accident!
CAUTION
■ Observe the recommendations on the new brake pads » page 74.■Never let the brakes slip with light pressure on the pedal if braking is not neces-
sary. This causes the brakes to overheat and can also result in a longer braking distance and excessive wear.

Information on braking
First read and observe the introductory information and safety warn-
ings
on page 68.
If the brakes are applied in full and the control unit for the braking system consid-
ers the situation to be dangerous for the following traffic, the brake light flashes
automatically.
After the speed was reduced below around 10 km/h or the vehicle was stopped,
the brake light stops flashing and the hazard warning light system switches on.
The hazard warning light system is switched off automatically after accelerating
or driving off again.
Before travelling a long distance at a steep gradient, reduce speed and shift into
the next lowest gear. As a result, the braking effect of the engine will be used,
reducing the load on the brakes. Any additional braking should be completed in-
termittently, not continuously.
Wear-and-tear
The wear of the brake pads is dependent on the operating conditions and driving
style.
The brake pads wear more quickly if a lot of journeys are completed in towns and over short distances or if a very sporty style of driving is adopted.
Under these severe conditions , the thickness of the brake pads must also be
checked by a specialist garage between service intervals.
Wet roads or road salt
The performance of the brakes can be delayed as the brake discs and brake pads
may be moist or have a coating of ice or layer of salt on them in winter. The
brakes are cleaned and dried by applying the brakes several times.
Corrosion
Corrosion on the brake discs and dirt on the bake pads occur if the vehicle has
been parked for a long period and if you do not make much use of the braking
system. The brakes are cleaned and dried by applying the brakes several times.
Faults in the brake surface
If it is found that the braking distance has suddenly become longer and that the
brake pedal can be depressed further, the brake system may be faulty.
Visit a specialist garage immediately and adjust your style of driving appropriatelyas you will not know the exact extent of the damage.
Low brake fluid level
An insufficient level of brake fluid may result in problems in the brake system. The
level of the brake fluid is monitored electronically » page 16, 
Braking system .
Brake booster The brake booster increases the pressure generated with the brake pedal. The brake booster only operates when the engine is running.
69Starting-off and Driving

When the accelerator pedal is fully depressed, the Kick-down function is activated
in any forward driving mode.
The gearbox shifts down one or more gears depending on the vehicle speed and engine speed, and the vehicle accelerates.
The gearbox does not shift up into the highest gear until the engine has reached
its maximum revolutions for this gear range.WARNINGRapid acceleration, particularly on slippery roads, can lead to loss of vehicle
control – risk of accident!

Emergency programme
The transmission switches to the emergency programme, if there is a fault in the
automatic transmission.
Indications of an activated emergency programme include the following.
› Only certain gears are selected.
› The reverse gear
R cannot be used.
Gearbox overheating
The gearbox may become too hot due to frequent repeated starting or stop-and-
go traffic, for example.
The vehicle does not start off after engaging the selector lever position
If the vehicle does not start off, the problem may be that the selector lever is not
completely in the selected position. In such an instance, press the brake pedal
and put the selector lever into the required position.

First read and observe the introductory information given on page 73.
The engine has to be run in during the first 1 500 kilometres.
Up to 1 000 kilometres
›
Do not drive faster than 3/4 of the maximum speed of the gear in use, i.e. 3/4 of
the maximum permissible engine speed.
›
No full throttle.
›
Avoid high engine speeds.
›
Do not tow a trailer.
From 1 000 up to 1 500 kilometres
Gradually increase the power output of the engine up to the full speed of the
gear engaged, i.e. up to the maximum permissible engine speed.
The red scale of the rev counter indicates the range in which the system beginsto limit the engine speed.
During the first operating hours the engine has higher internal friction than later until all of the moving parts have harmonized. The driving style which you adopt
during the first approx.1 500 kilometres plays a decisive part in the success of running in your car.
Never drive at unnecessarily high engine speeds even after the running-in period.
On vehicles fitted with a manual gearbox, at the very latest shift up into the next
gear when the red area is reached. Observe the recommended gear » page 12,
Recommended gear . Very high engine speeds when accelerating (accelerator) are
automatically restricted »

73Starting-off and Driving

In the following situation, it is possible that the tank cannot be fully filled with
natural gas.
› At very high ambient temperatures. The natural gas refuelling systems have
overheating protection. When the ambient temperature reaches a predefined value, the refuelling system automatically switches off.
› If the refuelling system has been in operation for a longer period, the filling
pressure of the natural gas refuelling system slightly drops.WARNING■ Stop the engine before refuelling.■Always switch off your mobile phone, do not smoke and do not use open
flames when refuelling with natural gas – risk of explosion!■
When refuelling, never get into the vehicle. If you have to get into your vehi-
cle in exceptional cases, close the door and touch a metal surface before you
touch the filling coupling again. This will avoid electrostatic discharges, which
may generate sparks. Sparks can cause a fire during refuelling.
■
Natural gas is highly explosive and flammable. Incorrect refuelling or improp-
er handling of natural gas can cause a fire, an explosion and injuries.
Note
■ The natural gas system of your vehicle is suitable both for fuelling from small
compressors (slow fuelling) and for fuelling from natural gas stations with large
compressors (quick fuelling).■
Noises that occur during refuelling represent no risk.
■
If the vehicle is parked for a longer period of time immediately after refuelling,
the situation may arise in which the pointer of the fuel tank gauge does not indi- cate exactly the same level as was the case immediately after refuelling when theengine is restarted. This is not due to any system leakages but a drop in pressurein the natural gas fuel tank due to technical reasons after a cooling phase directly
after refuelling.
■
For frequent short-haul traffic, especially at low outside temperatures, the vehi-
cle is driven more frequently in petrol mode than in natural gas mode. This is why the petrol tank runs empty faster than the natural gas tank.
■
The capacity of the natural gas tank is about 11 kg, of which about 1.5 kg are a
reserve.
■
The capacity of the petrol tank is about 10 l, of which about 5 l are a reserve.

Automatic switching from CNG to petrol mode
First read and observe the introductory information and safety warn-
ings
on page 123.
The vehicle automatically switches over from CNG mode to petrol mode when the following conditions are met:
› when starting the engine, if the coolant temperature is below 15 °C,
› when the natural gas tank is empty,
› after refuelling with natural gas.

Natural gas as fuel
First read and observe the introductory information and safety warn-ings
on page 123.
Natural gas is an alternative fuel for motor vehicles. Its main component is meth-
ane (CH 4). The rest is carbon dioxide and lower hydrocarbons.
The strict legal requirements for exhaust emissions of motor vehicles are decisive for the current significance of natural gas. In direct comparison to all other fossil
fuels, natural gas is one of the fuels which cause the lowest emissions.
Natural gas is odourless and lighter than air. For safety reasons, it is saturated
with odorous substances, so that is perceived even in very small amounts.

Regular gas system checks
First read and observe the introductory information and safety warn-ings
on page 123.
Every two years, the following inspections must be carried out:
› Check the condition of the fuel filler cap, filler neck and sealing ring, and clean
sealing ring if necessary.
› Check gas system for leaks.
The following checks must be carried out every four years: › Check gas tank mounting for secure attachment and possible damage.
The gas tank must be filled prior to the regular gas system check.

The coolant consists of water with coolant additive. This mixture guarantees anti- freeze protection, protects the cooling/heater system against corrosion and pre-
vents lime formation.
Vehicles exported to countries with a mild climate are already factory-filled with
a coolant which offers antifreeze protection down to about -25 ℃. In these coun-
tries, the concentration of coolant additive should be at least 40%.
Vehicles exported to countries with a cold climate are already factory-filled with a
coolant which offers antifreeze protection down to about -35 °C. In these coun-
tries, the concentration of coolant additive should be at least 50%.
If a higher concentration of antifreeze is required for climatic reasons, the con-centration of coolant additive can be increased up to a maximum of 60% (anti-
freeze protection down to approx. -40 °C).
When refilling, only use the antifreeze with the title given on the coolant expan-
sion tank » Fig. 108 on page 132.
WARNING■
The engine compartment of your car is a hazardous area. The following
warning instructions must be followed at all times when working in the en-
gine compartment » page 127.■
Do not continue your journey if for some reason it is not possible  to top
up the coolant under the prevailing conditions! Switch off the engine and seek
assistance from a specialist garage.
CAUTION
■ The concentration of coolant additive in the coolant must never be under 40%.■Over 60% of coolant additive in the coolant reduces the antifreeze protection
and cooling effect.■ A coolant additive that does not comply with the correct specifications can sig-
nificantly reduce the corrosion protection.■
Any faults resulting from corrosion may cause a loss of coolant and can conse-
quently result in major engine damage!
■
Do not fill the coolant above the mark
