Vehicle care and maintenance
Checking tyre pressures
Check tyre pressures only when the vehicle has not been driven for more
than a few kilometres at low speeds in the past three hours.
● Check tyre pressures regularly, and only when the tyres are cold. Always
check all tyres, including the spare wheel. Check tyre pressures more often
in colder regions, and only when the vehicle has not been driven recently.
Always use a correctly-operating tyre gauge.
● Adjust tyre pressures to the loads carried in the vehicle.
● After adjusting the tyre pressure, check that the caps are properly
screwed.
The spare wheel or temporary spare wheel must be at the maximum pres-
sure specified.
WARNING
If tyre pressures are too high or too low, the tyre may deflate or burst
suddenly while driving. This could result in serious accident.
● If the tyre pressure is too low, the tyres could overheat, resulting in
tread detachment or even burst tyres.
● When driving at high speeds and/or fully loaded, the tyre could sud-
denly overheat, burst or be subject to tread detachment, with the resul-
tant loss of control of the vehicle.
● Tyre pressures which are too high or too low reduce the service life of
the tyre, affecting the vehicle's performance.
● Tyre pressures should be checked regularly, at least once a month
and before long journeys.
● Adjust the pressures of all the tyres to the vehicle load.
● Never deflate excess pressure from hot tyres.
CAUTION
● Take care not to tilt the manometer when placing it on the valve. Other-
wise, the valve may be damaged.
● To avoid damage to the valves, always replace valve caps correctly.
Check that the caps are identical to the standard caps and have been cor-
rectly tightened.
For the sake of the environment
Under-inflated tyres will increase the fuel consumption. 
Tread depth and wear indicators
Fig. 122 Tyre tread:
tread wear indicators
Tread depth
Certain driving conditions require a deeper tread, as well as needing the
tread to be approximately the same on the front and rear tyres. This is par-
ticularly important when driving in winter, in cold temperatures and on wet
roads ⇒

WARNING
The components of the exhaust system reach very high temperatures.
This could cause a fire.
● Always park your vehicle so that no part of the exhaust system can
come in contact with flammable materials (such as dried grass).
● Never apply additional underseal or anti-corrosion coatings to the ex-
haust pipes, catalytic converter or the heat shields on the exhaust sys-
tem.

Note
While the control lamps  or  maintain lit up, the engine will present
faults, a higher consumption of fuel and a loss of engine power. 

● Passengers.
● Total equipment.
● Roof load, included in the carrier.
WARNING
Exceeding the maximum authorised weight and the load on the axles
could cause damage to the vehicle, accidents and serious injuries.
● The real load on the axles should never exceed the maximum permit-
ted.
● The load and its distribution in the vehicle have effects on the vehicle
handling and the braking ability. Always drive at a suitable speed.
CAUTION
Distribute the load as uniformly and as low down on the vehicle as possible.
When transporting heavy objects in the luggage compartment, these
should be placed as far forward as possible or over the rear axle to have as
little influence on handling as possible. 
Information on fuel consumption
The consumption and emission values indicated do not refer to one specific
vehicle. They are only to be used to compare the values of the different ve-
hicle versions. The fuel consumption and CO 2 emissions of a vehicle not on-
ly depend on the effective use of fuel. They also depend on your driving
style and other non-technical factors.
Calculation of fuel consumption
Fuel consumption and emission values are determined according to the cur-
rent version of the 715/2007/EC or 80/1268/EEC regulation and are valid
for the vehicle kerb weight. The specifications do not refer to an individualvehicle. To measure the fuel consumption, two measuring cycles are carried
out on a rolling road test bed. The test criteria are as follows:
Urban cycleMeasurement of the urban cycle starts with an engine cold
start. City driving is then simulated at between 0 and 50 km/
h (0 and 31 mph).
Road cycle
In the road cycle simulation, the vehicle undergoes frequent
acceleration and braking in all gears, as in normal everyday
driving. The road speed ranges from 0 to 120 km/h (0 and
75 mph).
CombinedThe average combined consumption is calculated with a
weighting of around 37 % for the urban cycle and 63 % for
the road cycle.
CO
2 emis-
sions of the
combinationThe exhaust gases are collected during both driving cycles
to calculate carbon dioxide emissions (urban and road). The
gas composition is then analysed to evaluate the CO 2 con-
tent and other emissions.
Note
The kerb weight may vary according to the vehicle equipment. This could
raise consumption and the CO 2 emissions slightly.
Note
In practice, consumption values could be different to the values calculated
based on the 715/2007/EC or 80/1268/EEC regulations. 
