Technical featuresUrban cycle
Measurement 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 car un-
dergoes frequent acceleration and
braking in all gears, as in normal every-
day driving. The road speed ranges
from 0 to 120 km/h (0 and 75 mph).
Combined
The 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
combination
The exhaust gases are collected during
both driving cycles to calculate carbon
dioxide emissions (urban and road).
The gas composition is analysed below
to evaluate the CO 2 content and other
emissions. Note
● The kerb w eight
may vary according to the
vehicle equipment. This could raise consump-
tion and the CO 2 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. Wheels

The stic

er with the tyre pressure values can
be found on the inside of the fuel tank flap.
The tyre pressure values are given for cold
tyres ››› page 200. The slightly raised pres-
sures of warm tyres must not be reduced.

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 al lo
y
wheels is 140 Nm. WARNING
● Check the ty
re 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 tight enin
g 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
Ser vic
e for information about appropriate
wheel, tyre and snow chain size. 211
