Parking
128WARNING■ Greater physical effort for braking is required when the engine is switch-
ed off – risk of accident!■
During the braking procedure on a vehicle with manual transmission,
when the vehicle is in gear and at low revs, press the clutch pedal. Other-
wise, the functionality of the brake system may be impaired – risk of acci-
dent!
■
When leaving the vehicle never leave persons leave unattended in the
vehicle who could release the brake. The vehicle might then move off – risk of accident!
■
Observe the recommendations on the new brake pads » page 132.
CAUTION
Never let the brakes slip with light pressure on the pedal if braking is not nec-
essary. This causes the brakes to overheat and can also result in a longer brak-
ing distance and excessive wear.
Information on braking
Read and observe
and on page 126 first.
Wear-and-tear
The wear of the brake pads is dependent on the operating conditions and driv-
ing 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.
If operated under severe conditions , the thickness of the brake pads must be
checked by a specialist garage between service appointments as well. 

Avoiding damage to your vehicle
Introduction
This chapter contains information on the following subjects:
Driving Tips
134
Driving through water
134
This section of the manual contains important information on preventing dam-
age to the vehicle while driving.
Driving Tips
Only drive on such roads and in such terrain, which match the vehicle parame-
ters » page 236 , Technical data as well as your driving skills.
The driver is always responsible for deciding whether the vehicle can handle
travelling in the given terrain.
When travelling off paved roads, we recommend activating the OFF ROAD
mode » page 138 .
WARNING■
Always adjust your driving to the current terrain and weather conditions.
Excessive speed or incorrect driving manoeuvres can cause damage to the
vehicle and lead to serious injuries.■
Combustible objects such as dry leaves or twigs caught under the base of
the vehicle could ignite on hot vehicle parts - risk of fire!
CAUTION
■ Pay attention to the ground clearance of the vehicle! When driving over ob-
jects which are larger than the ground clearance, the vehicle can get damaged.■
Any objects that get trapped under the vehicle floor must be removed as
soon as possible. These objects can damage the fuel lines, the brake system,
seals and other parts of the vehicle.
■
Drive slowly in unknown terrain and watch out for unexpected obstacles,
such as potholes, rocks, stumps, etc.
■
Check up on confusing sections of unpaved roads before travelling on them
and consider whether such travelling is possible without risk.
Driving through waterFig. 153
Maximum permissible water lev-
el when driving through water
The following must be observed to avoid damage to the vehicle when driving
through bodies of water (e.g. flooded roads).
›
Therefore determine the depth of the water before driving through bodies of
water.
The water level must not reach above the web of the lower beam » Fig. 153.
›
Do not drive any faster than at a walking speed.
At a higher speed, a water wave can form in front of the vehicle which can
cause water to penetrate into the air induction system of the engine or into
other parts of the vehicle.
›
Never stop in the water, do not reverse and do not switch the engine off.
CAUTION
■ If water penetrates into the intake system of the engine, there is a risk of se-
rious damage to the engine parts!■
When driving through water, some vehicle parts such as the chassis, the
electrics or the transmission can be severely damaged.
■
Oncoming vehicles can generate water waves which can exceed the permis-
sible water level for your vehicle.
■
Potholes, mud or rocks can be hidden under the water, making it difficult or
impossible to drive through the body of water.
■
Do not drive through salt water, as the salt can cause corrosion. An vehicle
coming into contact with salt water is to be thoroughly rinsed with fresh wa-
ter.
134Driving

Regularly remove salt and brake abrasion, otherwise the rim material will be
corroded.
Light alloy wheels
After washing thoroughly and treat the wheel rims with a protective product
for light alloy wheels.
For the treatment of wheel rims do not use products which may cause damage
to the paint on the rims.
CAUTION
■ Damage to the paint layer on the wheel rims must be touched up immediate-
ly.■
Severe layers of dirt on the wheels can also result in wheel imbalance. This
may show itself in the form of a wheel vibration which is transmitted to the
steering wheel which, in certain circumstances, can cause premature wear of
the steering. This means it is necessary to remove the dirt.
Towing hitch and mounting recess
Read and observe
and on page 183 first.
Seal the mounting recess with the cap to prevent any ingress of dirt.
In the event of dirt, clean the interior surfaces of the mounting recess and
treat with a suitable preservative.
Always check the ball head before attaching a trailer. Apply suitable grease
where necessary.
Include the protective cap when stowing away the ball rod to protect the boot
from getting contaminated.
CAUTION
Apply grease to the inner part of the mounting recess. Make sure you do not
remove any grease.
Under-body protection
Read and observe
and on page 183 first.
The underside of your vehicle is already permanently protected by the factory
against chemical and mechanical influences.
It is not possible to guarantee that the protective coating will not suffer any
damage as the vehicle is driven.
We recommend having the protective coating underneath the vehicle and the
chassis checked — preferably before the beginning of winter and at the end of winter.WARNINGNever use additional underbody protection or anti-corrosion agents for ex-
haust pipes, catalytic converters, diesel particle filters or heat shields.
When the engine reaches its operating temperature, these substances
might ignite - risk of fire!
Wiper blades
Read and observe
and on page 183 first.
Clean the wiper blades regularly with a glass cleaner. The wiper blades should
be cleaned with a sponge or cloth if they are heavily soiled by insect residues,
for example.
The wiper blades can become soiled with wax residues after washing in auto-
matic vehicle wash systems for example.

WARNING■
The operating instructions of the refuelling system must always be fol-
lowed.■
Do not smoke when refuelling and do not use a mobile phone.
■
The fuel and fuel vapours are explosive - risk to life!
CAUTION
■ Never drive until the fuel tank is completely empty! The irregular supply of
fuel can cause misfiring, which can result in damage to parts of the engine and
the exhaust system.■
Immediately remove any fuel that has spilled onto the vehicle's paintwork –
risk of paint damage.
■
If the vehicle was not purchased in the country where it was intended to be
operated, you should check whether the fuel specified by the manufacturer is
offered in the country where the vehicle will be operated. You should also per-
haps check whether the manufacturer has recommended a different fuel for
operation of the vehicle in the corresponding country. If no prescribed fuel is
available, then you must check whether it is permitted by the manufacturer to
operate the vehicle with another fuel type.

Incorrect refuelling guard on vehicles with diesel engines
The fuel filler tube on vehicles with diesel engines has been fitted with a in-
correct refuelling guard » Fig. 200. This guard means it is only possible to re-
fuel with the diesel pump nozzle.
If the diesel pump nozzle does not sit directly in the fuel filler tube, move it to
and fro with slight pressure to insert it correctly.
WARNINGInstructions for filling the reserve canister■Never fill the reserve can inside the vehicle.■
Never place the reserve can on the vehicle.
■
Always place the reserve can on the floor.
■
We do not recommend carrying any fuel canisters in your vehicle for safe-
ty reasons. in the event of an accident this can get damaged and fuel may
escape – risk of fire!
CAUTION
■ The fuel tank is full just as soon as the pump nozzle switches off for the first
time, provided the nozzle has been operated properly. Not continue refuelling.■
Be careful when filling diesel fuel from the spare canister and then do this
slowly and cautiously – danger of contaminating the body.
■
The diameter of the diesel pump nozzle can be identical to that of the petrol
pump nozzle in some countries. When driving in these countries, the incorrect
fuelling protection should be removed by a specialist company.
Note
The fuel tank has a capacity of about 50 litres, including a reserve of approx.
6 litres .Lead-free petrol
The correct fuel grades for your vehicle are specified on the inside of the fuel
filler flap.
Read and observe
and on page 189 first.
The vehicle can only be operated with unleaded petrol that meets the EN 2281)
standard.
All petrol engines can be operated using petrol that contains at most 10% bio-
ethanol (E10).
Unleaded petrol 95/91 or 92 or 93 RON/ROZ
We recommend using unleaded fuel with an octane rating of 95 RON. Unlea-
ded petrol with the octane ratings 91, 92 or 93 RON can also be used, but may
result in a slight loss in performance and slightly increased fuel consumption.
Unleaded petrol min. 95 RON / ROZ
Use unleaded fuel with the octane rating 95 RON or higher.
In an emergency petrol with the octane ratings 91, 92 and/or 93 RON can also
be used, but may result in a slight loss in performance and slightly increased
fuel consumption. Continue driving at medium engine speeds and minimum
engine load »
.
Refuel using petrol of the prescribed octane number as soon as possible.
Unleaded petrol 98/(95) RON / ROZ
We recommend using unleaded fuel with an octane rating of 98 RON or higher.
Unleaded petrol 95 RON can also be used but this results in a slight loss in per-
formance and slightly increased fuel consumption.
In an emergency petrol with the octane ratings 91, 92 and/or 93 RON can also
be used, but may result in a slight loss in performance and slightly increased
fuel consumption. Continue driving at medium engine speeds and minimum

for unleaded petrol with octane number 95 and 98.
190General Maintenance

Preheating fuel
The vehicle is fitted with a fuel filter preheating system. This secures opera-
tion of a vehicle using diesel fuel down to an environmental temperature of
-24 °C.
Diesel fuel additives
The diesel fuel in accordance with the prescribed standards meets all the con-
ditions for a smooth running engine. We therefore recommend that no diesel
fuel additives are used. This can result in considerable damage to parts of the
engine or the exhaust system.
CAUTION
■ Just filling the tank once with diesel fuel that does not comply with the
standard, can cause severe damage to parts of the engine, the fuel and ex-
haust system.■
If a different fuel other than diesel fuel, which complies to the above men-
tioned standards (e.g. petrol) is used, do not start the engine or switch on the
ignition! Extensive damage to engine parts can occur.
■
Water which has collected in the fuel filter can cause engine faults.
CAUTION
■ The vehicle cannot be operated with bio fuel RME, therefore this fuel must
not be filled in the tank and used for driving the vehicle. The use of biofuel
RME can cause considerable damage to parts of the engine or fuel system.■
Do not mix any fuel additives, so-called “flow improvers” (petrol and similar
agents) into the diesel. This can result in considerable damage to parts of the
engine or the exhaust system.
Refuelling with CNG (compressed natural gas)
Fig. 201
Natural gas filler tubes
Read and observe and on page 189 first.
Natural gas refuelling can be carried out if the following conditions are met.
The vehicle is unlocked.
The engine and the ignition are switched off.
The auxiliary heating and ventilation is switched off » page 118.
The gas filler tube for refuelling with natural gas is located behind the fuel fill-
er flap next to the petrol filler tube.
The filling couplings of the natural gas refuelling systems may differ in han-
dling. When refuelling with natural gas at unfamiliar refuelling systems, you
should seek help from trained fuel station staff. If unsure, have the refuelling
done by trained fuel station staff.

The natural gas refuelling systems have an overfill protection relating to the
outdoor temperature. At very high outside temperatures, it may happen that
the gas tank may not be fully refuelled.
The natural gas system of your vehicle is suitable both for “slow fuelling” (fuel-
ling from small compressors) and for “quick fuelling” (fuelling from natural gas
stations with large compressors).
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
indicate exactly the same level as was the case immediately after refuelling 

192General Maintenance

when the engine is restarted. This is not due to any system leakages but a
drop in pressure in the natural gas fuel tank due to technical reasons after a
cooling phase directly after refuelling.
The maximum lifetime of the gas tank is 20 years.
The capacity of the natural gas fuel tank is approximately 15 kg.
The capacity of the gasoline fuel tank is about 50 litres, of which about 6
lighters are in reserve.WARNING■
When refuelling, never get into the vehicle. If you have to get into your
vehicle in exceptional cases, 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 highly flammable.
Note
During the filling process sounds are heard which are harmless. If you are un-
sure which service station staff to use, ask the petrol station staff.
CNG

and on page 189 first.
A G-TEC-vehicle may be operated with CNG and petrol.
In some countries, national legislation requires that vehicles with CNG opera-
tion be identified by one of the labels » Fig. 202.
Position of the CNG label » Fig. 202.
Natural gas quality and consumption
Depending on the natural gas supplier, the natural gas quality (heating value) may vary. The engine system adjusts automatically to the natural gas quality.
Automatically switching over from natural gas mode to petrol mode
The vehicle automatically switches from natural gas to petrol, for example, if
one of the following cases occurs. ▶ With an empty gas tank or not enough pressure in the tank.
▶ After refuelling with natural gas.
▶ At very low surrounding temperatures.
Use all the petrol in the fuel tank at lease once every six months until the
warning light 
illuminates and then refill with petrol. This is to ensure that
the fuel system functions correctly and to preserve the quality of the fuel.
Gas leak
If a gas leak is suspected (noticeable odour), proceed as follows. ▶ Stop the vehicle.
▶ Switch off the ignition.
▶ Put out any cigarettes, remove any spark-producing or incendiary items from
the vehicle and immediately switch the engine off.
▶ Open the doors and the boot lid to ventilate the vehicle sufficiently.
▶ Do not continue to drive if the odour persists.
▶ If it is not possible to leave an enclosed area with a vehicle with a gas leak
(e.g. in a tunnel, underpass, garage, ferry, etc.), call the emergency services
immediately.
Seek help from a specialist garage to correct the gas system fault.
In a traffic accident
If a gas leak is suspected in a traffic accident, proceed as follows.
▶ Switch off the ignition.
▶ Put out any cigarettes, remove any spark-producing or incendiary items from
the vehicle and immediately switch the engine off.
▶ Have all the occupants get out.
▶ Prevent people walking past/standing in the immediate vicinity of the acci-
dent vehicle. We recommend standing at least 10 metres from the vehicle.
▶ Inform the emergency services that it is a natural gas vehicle.
Regular gas system checks
Regular gas system checks must be carried out in a specialist workshop on
natural gas-powered vehicles. The vehicle owner is responsible for ensuring
tests are conducted properly. 193Inspecting and replenishing
