Driving and operating109
Permanent deactivation
Permanently deactivate the system
by pressing and holding the E button
on the instrument panel for approx. 3 seconds with the ignition on and
reverse gear engaged. The system is deactivated and will not operate.
When reverse gear is selected no
acoustic signal will sound, indicating
deactivation.
The function is reactivated by
pressing and holding button E for
approx. 3 seconds.
Fault
If the system detects an operating
fault, a continuous acoustic alarm will sound for approx. 5 seconds whenselecting reverse gear. Consult a
workshop to have the cause of the
fault remedied.Caution
When reversing, the area should
be free from obstacles which could
impact on the underside of the
vehicle.
Impact to the rear axle, which may
not be visible, could lead to
uncharacteristic changes in the
vehicle handling. In the event of
such an impact, consult a
workshop.Fuel
Fuel for petrol engines Only use unleaded fuel that complies
with European standard EN 228 or
E DIN 51626-1 or equivalent.
Your engine is capable of running
with E10 fuel that fulfills these
standards. E10 fuel contains up to
10 % bioethanol.
Use fuel with the recommended octane rating 3 154. Use of fuel with
too low an octane rating can reduce
engine power and torque and slightly
increases fuel consumption.Caution
Do not use fuel or fuel additives
that contain metallic compounds
such as manganese-based
additives. This may cause engine
damage.

138Vehicle care
Put wheel bolts somewhere
where the threads will not be
soiled.
6. Change the wheel.
7. Screw in the wheel bolts.
8. Lower vehicle.
9. Tighten each wheel bolt in a crosswise sequence. Tighteningtorque is 140 Nm.
10. Refit wheel cover
11. Change the wheel.
12. Stow the replaced wheel 3 138
and the vehicle tools 3 131.
13. Have the new wheel balanced on the vehicle. Check the tyre
pressure of the installed tyre
3 163 and also the wheel bolt
torque as soon as possible.
Have the defective tyre renewed or
repaired.
Spare wheel Some vehicles are equipped with a
tyre repair kit instead of a spare wheel
3 133.Use of a spare wheel that is smaller
than the other wheels or together with winter tyres could affect driveability.
Have the defective tyre replaced as
soon as possible.
The spare wheel is mounted under
the rear underbody and may be
secured using a security bolt that can
only be removed using the tool
supplied.
9 Warning
Due to the weight of the tyre
assembly, exercise caution when
releasing the spare wheel carrier.
Do not fully remove bolt 1.
Support the spare wheel with a
suitable object to prevent the
wheel falling suddenly when
loosening the carrier bolts - risk of injury!
It may be necessary to jack the
vehicle up to gain access to the spare wheel on a fully loaded vehicle with a
flat rear tyre.
To release the spare wheel carrier,
loosen bolt 1, ensuring it is not fully
removed. Fully remove bolt 2, then
pull the carrier to the left, until it clears bolt 1, and lower the carrier assembly.
When installing the wheel ensure that
the spare wheel carrier is correctly
positioned before tightening the bolts.
