Measurement of the urban cycle starts with

mulated at between 0 and 50 km/h (0 and
31 mph).
In the road cycle simulation, the car under-
goes frequent acceleration and braking in all
Road
gears, as in normal everyday driving. The
cycle
road speed ranges from 0 to 120 km/h (0
and 75 mph).
The average combined consumption is calcu-
Com-

urban cycle and 63 % for the road cycle.

The exhaust gases are collected during both
emis-
driving cycles to calculate carbon dioxide
sions of
emissions (urban and road). The gas compo-

sition is analysed below to evaluate the CO
combi-
content and other emissions.

Note
●
The kerb weight may vary according to the
vehicle equipment. This could raise consump-
tion and the CO
emissions slightly.

In practice, consumption values could be
different to the values calculated based on
the 715/2007/EC or 80/1268/EEC regula-
tions.

Tyre pressure, snow chains, wheel
bolts
Tyre pressures
The sticker with the tyre pressure values can
be found on the inside of the fuel tank flap.
The tyre pressure values given there are for
cold tyres. The slightly raised pressures of
warm tyres must not be reduced.
Snow chains
Snow chains may be fitted only to the front
wheels.

Consult the section "wheels" of this manual.
Wheel bolts
After the wheels have been changed, the
tightening torque of the wheel bolts should
be checked as soon as possible with a torque
›››
wrench
. The tightening torque for steel
and alloy wheels is 140 Nm.
WARNING
●
Check the tyre pressure at least once per
month. Checking the tyre pressure is very im-
portant. If the tyre pressure is too high or too
low, there is an increased danger of accidents
- particularly at high speeds.
If the tightening torque of the wheel bolts
●
is too low, they could loosen while the vehi-
cle is in motion. Risk of accident! If the tight-
ening torque is too high, the wheel bolts and
threads can be damaged.
Note
We recommend that you ask your Technical
Service for information about appropriate
wheel, tyre and snow chain size.
