The warning lights in the instrument cluster indicate certain functions or
faults.
Some warning lights can be accompanied by acoustic signals and messages in
the display of the instrument cluster.
After switching on the ignition, some warning lights light up briefly as a func-
tion test. If the tested systems are OK, the corresponding warning lights go
out a few seconds after switching on the ignition or after starting the engine.
The warning lights are located at the following positions in the instrument
cluster » Fig. 17 on page 30 .

Data overview
Overview of driving data (depending on the vehicle equipment).
Range - Drive distance in km which can be covered with the existing tank ca-
pacity and with the same driving style. If you drive more efficiently this value
can increase. With G-TEC vehicles the following details are displayed - total
range / with natural gas / petrol.
Average fuel consumption - Is calculated continuously since the last time that
the memory was erased. After erasing the memory, no data will appear for the
first 100 m driven. With G-TEC vehicles, the average consumption of fuel cur-
rently being used is displayed.
Current fuel consumption - When the vehicle is stationary or moving slowly,
the fuel consumption is displayed in l/h (in models in some countries the fol-
lowing appears --,- km/l). With G-TEC vehicles the current consumption of the
fuel currently being used is displayed ( with regards to a stationary or slow
moving vehicle, the natural gas consumption is displayed in kg/h).
Oil temperature if the temperature is lower than 50 °C or if there is a fault in
the system for checking the oil temperature, the symbols are displayed.
Warning at when the preset speed is exceeded allows the setting of a speed
limit where, if exceeded, an acoustic warning signal and a warning message
appears on the display of the instrument cluster.
Dynamic Road Sign Display - traffic signs display » page 226, Traffic sign rec-
ognition .
Current Speed - Digital speedometer.
Average speed - Value constantly recalculated, for distance since last clearing
the memory. After erasing the memory, no data will appear for the first 300 m
driven.
Distance driven - Distance driven since the memory was last cleared.
Driving time - Driving time since last clearing the memory.
Conv. consumers - information about the total consumption of the comfort
consumers in l/h and a list of three consumers (e.g. air conditioning etc.), which
have the largest share of fuel consumption.
Refill amount 1)
After the consumption of about 10 litres of fuel from the fully
refuelled tank, an amount of fuel is displayed in l. This amount can now be
safely refilled.
Natural gas quality The details of the quality of natural gas are displayed as a
percentage of between 70% to 100%. The higher the value of natural gas, the lower is the consumption.
Coolant temperature - If the coolant temperature is in the range 70-120 °C,
the engine operating temperature has been reached. If the temperature is be-
low 70 ° C, high engine speeds and straining the engine should be avoided. If the temperature is over 120°C, the warning light » page 38
illuminates in the
instrument cluster .

44Using the system
The longer insect residues, bird droppings, road salt and other aggressive de-
posits remain on the paintwork of your vehicle, the more detrimental their de-
structive effect can be. High temperatures, such as those caused by intensive
sun's rays, accentuate this caustic effect.
It is also essential to thoroughly clean the underside of the vehicle at the end
of the winter.
Washing by hand
Wash the vehicle from top to bottom, with a soft sponge or a wash mitt and
plenty of water, and, if necessary, with the appropriate detergents. Wash out
the sponge or washing glove thoroughly at short intervals.
For wheels, door sills and lower areas of the vehicle use a different sponge.
Give the vehicle a good rinse after washing it and dry it off using a chamois
leather.
Automatic Car Washes
The usual precautionary measures must be taken before washing the vehicle
(e.g. closing the windows and the tilt/slide roof etc.).
If your vehicle is fitted with any particular attached parts (e.g. spoiler, roof rack system, two-way radio aerial etc.) it is best to consult the operator of the car
wash system beforehand.
After an automatic wash with wax treatment, the wiper blades should be
cleaned with cleaning agents specially designed for the purpose, and then de-
greased.
Pressure Washers
When washing the vehicle with a high-pressure cleaner, the instructions for
use of the equipment must be observed. This particularly applies to instruc-
tions regarding the pressure and spraying distance from the vehicle surface.WARNING■
When washing your vehicle in the winter: Water and ice in the braking
system can affect the braking efficiency – risk of accident!■
Take care when cleaning the underbody or the inside of the wheel wells -
there is a risk of injury from sharp metal parts!
CAUTION■ Do not wash the vehicle in direct sunlight, do not exert pressure on the body
while washing. The temperature of the washing water should be no more than
60 °C max. - otherwise there is a risk of damaging the vehicle paint.■
Before driving through a car wash fold in the exterior mirrors - There is a risk
of damage.
CAUTION
Washing the vehicle with high-pressure cleaners■Films should not be washed with any high-pressure cleaners - risk of dam-
age.■
Do not aim the water jet directly at the lock cylinders or the door or opening
joints when washing the vehicle in the winter – there is a risk of freezing.
■
During cleaning, always keep a sufficiently large spraying distance to the
parking sensors, the rear camera lens, to external decorative and protective
plastic parts (e.g. Roof racks, spoilers, protective strips) and other vehicle parts
made of non-metallic materials such as rubber hoses or insulation materials.
■
The sensors of the parking aid can be sprayed only for a short time and there
must be a minimum distance of 10 cm - there is a risk of damage.

Mild soap solution = 2 tablespoons of natural soap to 1 litre of lukewarm water.
The jack is maintenance-free. If necessary, the moving parts of the jack should
be lubricated with a suitable lubricant.
The towing device is maintenance-free. Coat the ball head of the towing de-
vice with a suitable grease whenever necessary.
Protection of cavities
All the cavities of your vehicle which are at risk from corrosion are protected by
a layer of long-lasting protective wax applied in the factory.
If any small amount of wax flow out of the cavities at high temperatures, these
must be removed with a plastic scraper and the stains cleaned using a petrole-
um cleaner.
Underbody
The underside of your vehicle is already permanently protected by the factory
against chemical and mechanical influences.
We recommend having the protective coating — preferably before the begin-
ning of winter and at the end of winter.
Product life of the films
Environmental influences (e.g. sunlight, humidity, air pollution, rockfall) affect
the life of the films. Films will age and become brittle – this is entirely normal;
this is not a fault.
Sunlight may also affect the strength of the film colour.
When transporting a load on the roof rack (e.g. roof box or similar), there is an
increased risk of film damage (e.g. of chipping from the secured load).
CAUTION■ Vehicle paint
■ Repair damaged areas as soon as possible.
■ Matt-painted parts should not be treated with polishes or hard waxes.
■ Do not polish in a dusty environment - risk of paint scratches.
■ Do not apply any paint care products to door seals or window guides.■
Plastic parts
■ Do not use paint polish.
■
Chromed and anodised parts
■ Do not polish in a dusty environment - risk of surface scratches.
■
Films
The following instructions must be observed, otherwise there is a risk of film
damage. ■ Do not use dirty cloths or sponges for cleaning.
■ Do not use a scraper or other means to remove ice and snow.
■ Do not polish the films
■ Do not use a high pressure cleaner on the films.
■
Rubber seals
■ Do not treat the door seals and window guides deal with anything - the
protective varnish coating could be damaged.
■
Windows and door mirrors ■ Do not clean the insides of the windows/mirrors with sharp objects - There
is a risk of damage to the filaments or the antenna. ■ Do not use a cloth which has been used to polish the body - this could dirty
the window and impair visibility.
■
Head / tail lights
■ Do not wipe head/tail lamps dry, do not use any sharp objects - risk of dam-
age to the protective coating and cracks forming on the headlamp glass cov-
ers.
■
Reversing camera
The following instructions must be observed, otherwise there is a risk of
camera damage.
■ Do not remove snow / ice with warm / hot water.
■ To wash, never use a pressure washer or steam jet.
■ For cleaning, do not use abrasive cleaners.
■
Door lock cylinders
■ Make sure that as little water as possible gets into the locking cylinder
when washing the vehicle - there is a risk of freezing the lock cylinder!
■
Wheels
■ Heavy soiling of the wheels can affect the balance of the wheels - the re-
sult can be a vibration, which can cause premature wear of the steering.

Coolant
Introduction
This chapter contains information on the following subjects:
Checking and refilling
257
The coolant helps to keep the engine temperature down, and consists of wa-
ter and coolant additive (with additives that protect the cooling system against
corrosion and prevent furring).
The proportion of coolant additive in the coolant must be 40 to 60 %.
The correct mix of water and coolant additive should be checked and if neces-
sary corrected by a specialist garage.
WARNING■ The following instructions must be followed at all times when working on
the engine compartment » page 252.■
Never open the end cover of the coolant expansion reservoir while the
engine is still warm. The cooling system is pressurised - risk of scalding or
injury from splashes of coolant!
■
To protect against the coolant splashing, cover the cap with a cloth when
opening.
■
Coolant and coolant fumes are harmful - avoid contact with the coolant. If
the coolant comes into contact with the eye or skin, wash the affected area
with plenty of water for several minutes, and where appropriate seek medi-
cal help.
CAUTION
Do not cover the radiator and install any parts (e.g auxiliary lights.) in front of
the air intakes - There is a risk of the engine overheating.256General Maintenance
