Suggestion 6. Avoid short drives
The engine and the catalytic converter must reach its optimum
functioning temperature in order to effectively reduce consumption
and toxic gas emissions.
The fuel consumption of a cold engine of a normal vehicle right
after the start is about 30-40 liters per 100 km. After about one
kilometer the consumption decreases to 20 liters. After about
f fo
ou
ur
r
kilometers the engine has warmed up and the consumption is
normal. For this reason, it is important to avoid short drives and
heating the vehicle’s engine when the vehicle is not moving. Drive
on quickly!
The ambient temperature also counts. The illustration shows the
difference in consumption (l/100km) for the same distance (km) at
+20°C and –10°C. Your vehicle’s consumption is higher in the
summer than in the winter
⇒fig. 102.K
Suggestion 7. Check the tyre pressure
Make sure that the tyres have always adequate pressure. Even half
a bar less increases the level of fuel consumption by 5 percent. If
the pressure is not correct, the tyres wear out faster due to an
excessive deformation and overheating which, in turn, will
decrease the driving performance.
Always check the tyre pressure when the tyre is cold.
In addition, do not drive year round with winter tyres. They make
more noise and increase fuel consumption by 10 percent. Change
to summer tyres on time.
K
Suggestion 8. Avoid unnecessary weight
Apart from driving habits and periodic revisions of your vehicle,
there are other ways to reduce fuel consumption:

Every kilogram increases fuel consumption. For this reason, it is
worth checking your boot to avoid unnecessary weight.
Frequently, the roof rack will stay on the roof even though it is no
longer needed. Due to greater air resistance, an unloaded roof
rack at a speed of 100-120 km/h increases the consumption by
approx. 12%.

178If and when
• You should only combine radial tyres of the same construction,
size (rolling circumference) and, as far as possible, the same tread
profile on all four wheels.
•If the spare wheel has got a different use than the wheels the car
is using actually (for example, winter tyres or wide tyres), in case of
a breakdown it will only be possible to be used for a short time and
driving with special care. It will have to be replaced by the normal
wheel as soon as possible.
• Never fit used tyres whose previous history is not known.
• Knowing the tyre lettering and its meaning makes the selection
of the correct tyres easier. Radial ply tyres have the following
lettering on the sidewall:

(possibly only on inner side of wheel):

Changing the wheels round
If the front tyres are worn more than the rear it is advisable to
change the wheels round as shown. All tyres will then have
approximately the same length of service life.With certain types of tread wear it can be an advantage to change
the wheels diagonally. For more details, contact a Technical Service
Centre.
K
Winter tyres
When fitting winter tyres note the following:
• For better driving performance, fit winter tyres on all four wheels.
• Winter tyres are no longer fully effective when the tread has worn
down to a depth of 4 mm.
The following speed limits are valid for winter tyres:
Code letter Q max. 160 km/h
Code letter T max. 190 km/h
Code letter H max. 210 km/h

Please note regulations to this effect in your country.
• All-weather tyres can also be used instead of winter tyres.
• If you have a flat tyre the remarks on using the spare wheel on
page 174 should be noted.
• Do not leave winter tyres fitted for an unnecessary long period
because when the roads are free of snow and ice the handling with
summer tyres is better.

For environmental reasons summer tyres should be fitted again as soon as
possible because normally they are quieter in running, tyre wear is reduced
and the fuel consumption is lower.
K
Snow chains
Snow chains can only be fitted on the front wheels.
The use of snow chains is permitted on 155/80 R 13, 165/70 R 14
and 185/60 R 14 tires.

When using snow chains wheel rim plates and rim rings must be
taken off. In this case, to protect the wheel, the bolts must then be
fitted with caps which are available from Technical Service Centres.When driving over roadswhich are free of snow you must remove
the chains. On such roadsthey are detrimental to vehicle handling,
damage the tyres and wear out quickly.
In some countries the maximum permissible speed with snow
chains is 50 km/h.

Preparation work
– In case of a flat tyre or puncture, park the vehicle as far as
possible away from the traffic flow. If necessary, switch hazard
warning lights on and place the warning triangle in position – note
any statutory requirements.
– All vehicle occupants should leave the vehicle and move to a
safe area (e.g. behind safety barrier).
– Apply handbrake firmly, engage a gear or place the gear selector
in position “P” and chock the opposite wheel with a stone or
similar.
– When towing a trailer, the trailer must first be disengaged from
the towing vehicle before the wheel is changed.
– Take tools and spare wheel out of luggage compartment.
