The fuel consumption can naturally also be
influenced by factors which are beyond
the driver's control. It is,
for example, normal for the fu
el consumption to increase
in winter and under worsened
conditions such as poor road conditions, towing a
trailer, etc. The technical requirements for low fuel
usage and economic efficiency of the
vehicle have already been built into the ve
hicle at the works.
Special attention has
been given to minimising ne
gative effects on the environment. It is necessary to
take note of the guidelines given in this
chapter in order to make best use of these
characteristics and to maintain their effectiveness. The optimal engine speed should be obtained when accelerating, in order to avoid a high fuel consumption an
d resonance of the vehicle.
Looking ahead when driving A vehicle's highest fuel consumption occurs it accelerates.Avoid accelerating and brakin
g unnecessarily. If you drive
with forsight you will not
need to brake so often and will also then
not have to accelerate so much. Let your
vehicle coast to a stop, for example, if this
is possible, when you see that the next
set of traffic lights is at red.Shifting gears and saving energy Shifting up early saves on fuel.
Manual gearbox – Drive no more than about one length of your vehicle in first gear. – Always shift up into the next higher gear at approx. 2 000 to 2 500 revs. Automatic gearbox – Depress the accelerator pedal
slowly
. Do not depress it beyond the
kickdown position, however.
An effective way of achieving good
fuel economy is to shift up
early
. You will
consume more fuel if you drive at unnecessa
rily high revolutions in any given gear.
The
⇒fig. 194
shows the ratio of fuel consumption to the speed of your vehicle in
the relevant gears. Fuel consumption in 1st
gear is the highest, while that in 5th or
the 6th gear is the lowest. Only depress the accelerator pedal slowly if
your vehicle is fitted with an automatic
gearbox in order to automatically select an economic driving programme. You will achieve good fuel economy by shifting
up early and shifting down late.

WARNING
•
Never open the bonnet if you see that steam or coolant is flowing out of
the engine compartment - risk of scaldi
ng! Wait long enough until the steam
or coolant has stopped escaping.•
For safety reasons, the bonnet must always be properly closed when
driving. One should therefore check that
the lock has in fact engaged prop-
erly after closing the bonnet.•
Stop your vehicle immediately while driv
ing if you notice that the lock is
not properly engaged and close the bonne
t properly - risk of an accident!
Caution
Ensure that the arms of the windscreen
wipers are correctly
in place against the
windscreen before opening the bonnet otherwise damage could occur to the paintwork.Working in the engine compartment Particular care is required when carrying out any work in the engine compartment!There is a risk of injuries, scalding,
accidents and fire when working in the
engine compartment, e.g. inspecting and replenishing oil and other fluids. For this reason, it is essential to comply with the warning instructions stated below and with the general applicable
rules of safety. The engine compart-
ment of your car is a hazardous area
⇒
.
WARNING
•
Never open the bonnet if you see that steam or coolant is flowing out of
the engine compartment - risk of scaldi
ng! Wait long enough until the steam
or coolant has stopped escaping.•
Switch off the engine and pull out the ignition key.
•
Apply the handbrake firmly.
•
If your vehicle is fitted with a ma
nual gearbox, move the gearshift lever
into Neutral, or if it is fitted with
automatic gearbox, move the selector lever
into position P.•
Allow the engine to cool down.
•
Keep children clear of the engine compartment.
•
Never spill oil and other fluids over the hot engine. Such fluids (e.g. the
antifreeze contained in the coolant) may ignite!•
Avoid short circuits in the electrical system - particularly on the battery.
•
Never place your hand into the radiator fan as long as the engine is still
warm. The fan might suddenly start running!•
Never open the cap of the coolant expa
nsion bottle as long
as the engine
is still warm. The cooling system is pressurized!•
Cover over the cap of the coolant expansion reservoir with a large cloth
when opening it as protection for your
face, hands and arms from hot steam
or hot coolant.•
Do not let objects, such as e.g cleani
ng cloth or tools lie in the engine
compartment.•
If you wish to work under the vehicle, you must secure the vehicle from
rolling away and support it with suitable supporting blocks: the car jack is not sufficient for this - risk of injury!•
In cases where it be necessary to carry out inspection work when the
engine is running there is an additional risk from rotating parts (e.g. the V- ribbed belt, alternator, radiator fan) and from the high-voltage ignition system. Please observe in addition the following.
− Never touch the electrical cabl
es of the ignition system.
− Absolutely avoid any jewellery, loose items of clothing or long hair from getting into the rotating parts of the engine - Hazard! Therefore remove any jewellery beforehand, tie up your hair and wear tight fitting clothing.
•
Please also comply with the warnin
g instructions stated below when
carrying out any essential work on th
e fuel system or on the electrical
system.

One should check the inflation pressure in the spare wheel (at best when generally checking the tyre air pressures - see sign on the fuel filler flap
⇒page 235) to
ensure that the spare wheel is always ready to use. Temporary spare wheel A warning label displayed on the rim of the temporary spare wheel indicates that your vehicle is equipped with a temporary spare wheel. Please observe the following notes when driving with a temporary spare wheel:•
After fitting on the wheel, the warning stic
ker must not be concealed (e.g. by the
wheel trim).•
Do not drive with this spare wheel at more than 80 km/h - risk of accident. Avoid
accelerating at full throttle, sharp braking and fast cornering.•
The inflation pressure for this spare wheel is identical to the inflation pressure
of the standard tyres. The temporary spare wheel R 18 must have an inflation pres-sure of 420 kPa (4.2 bar)!
•
Use this spare wheel only to reach the nearest specialist garage as it is not
intended for continuous use.•
No other summer or winter tyres must
be mounted on the rim of the spare
wheel R 18.Changing a wheelPreliminary workThe following steps should be carried out before actually changing the wheel. – If it is necessary to change a wheel, park the vehicle as far away as
possible from the traffic flow. The place you choose should be

Tow-starting and towing vehicleGeneralPlease pay attention to the following in
structions if you are going to use a
tow rope: Driver of the towing vehicle – Do not drive off until the tow rope is taught. – Release the clutch particularly gent
ly when starting off or depress the
accelerator particularly gently if yo
ur vehicle is fitted with an auto-
matic gearbox.
Driver of the towed vehicle – Switch the ignition on so that th
e steering wheel is not blocked and
you can also operate the turn signal
lights, the headlight flasher, the
windscreen wipers and windscreen washer system.
– Take the vehicle out of gear or move the selector lever into position
N
if your vehicle is fitted
with an automatic gearbox.
– Note that the brake servo unit and po
wer steering only operate if the
engine is running. You will require
significantly greater physical force
to depress the brake pedal and to steer the vehicle if the engine is not running.
– Ensure that the tow rope is always kept taught.Tow rope or tow bar A tow
bar
is safest way of towing a vehicle and also minimizes any shocks. You can
use a tow
rope
only if a suitable tow bar is not available.
The tow rope must be elastic to protect
the vehicle. Thus one should only use
plastic fibre rope or a rope made
out of a similarly elastic material.

and
⇒page 254.
Driving style Towing another vehicle requires a certain
amount of practice. Both drivers should
be familiar with the particular points
about towing a vehicle. Unskilled drivers
should not attempt to tow in another vehicle or to be towed in. One should be constantly vigilant not to
allow impermissibly high towing forces or
jerky loadings. There is always a risk of excessive stresses and damage resulting at the points to which you attach the tow rope or tow bar when you attempt to tow a vehicle which is not standing on a paved road.
Caution
If the gearbox of your vehicle no longer
contains any oil because of a defect, your
vehicle must only be towed in with the driv
en wheels raised clear of the ground, or
on a special vehicle transporter or trailer.
Note
•
Please comply with any legal requirements particularly regarding the switched
on signal systems, when towing in
or tow-starting
another vehicle.
•
The tow rope must not be twisted as it may in certain circumstances result in the
front towing eye being unscr
ewed out of your vehicle.
Front towing eye The towing eye is stored in th
e box for the vehicle tool kit.
– Take the cover out of the front bumper
⇒
fig. 224
.
– Screw in the towing eye anticlockwise down to the stop
⇒
fig. 225
and
tighten up using the wheel wrench (push the wheel wrench through eye).
– Put the cover in place after screwing out the towing eye again and
press into place. The cover must engage firmly.

and
tighten up using the wheel wrench (push the wheel wrench through eye).
– Put the cover in place after screwing out the towing eye again and
press into place. The co
ver must engage firmly.
Tow-starting a vehicleIf the engine does not start, we generally do
not
recommend
to tow-start
your vehicle. One should attempt to start the engine using jump start cables
⇒
page 250 or call on the services of the SERVICE mobile.
If your vehicle has to be towed – Engage 2nd or 3rd gear wi
th the vehicle stationary.
– Depress the clutch pedal fully and keep it depressed. – Switch on the ignition.– Wait until both vehicles are movi
ng then release the clutch pedal
slowly.
– Depress the clutch pedal fully when the engine fires and take the
vehicle out of gear.
For technical reasons it is not possib
le to tow-start a car fitted with an
automatic
gearbox
.WARNING
There is high risk of having an accident when tow-starting a vehicle, when for example the towed vehicle runs into the towing vehicle.
Caution
Vehicles which are fitted with a catalytic
converter should not be tow-started over
a d i s t a n c e o f m o re t h a n 5 0 m e t re s . U n b u r n
t fuel may get into the catalytic converter
and damage it.Towing in a vehicle fitted with a manual gearboxPlease refer to the notes
