improper workon two-w ayradios
The elect romagnetic radiation from two-w ay
ra dios can inter fere with the on-board elec‐
tronics if RF transmit ters are manipulated or

WARNING Risk of accident from incor‐
re ct ope ration of two-w ayradios
If yo u operate two- wayra dios inco rrectly in
th eve hicle, the electromagnetic radiation
could inter fere with the on-board electronics,
e.g.:
R ifth e two-w ayradio is not connec tedto
an exterior aerial
R ifth eex terior aerial is not cor rectly
mounted or is not of low reflection
This could jeopardise the operating saf ety of
th eve hicle. #
Have the lo w-reflection exterior aerial

WARNING Risk of an accident due toinsuf ficient tyre pressure
Ty res with insuf ficient tyre pressure pose thefo llowing risks:
R The tyres may bur st, especially as the load and vehicle speed increase.
R The tyres may wearexc essively and/or une venly, which may greatly impair tyre traction.
R ‑ The driving characteristics, steering and braking may be greatly impaired.
Yo u could then lose control of theve hicle. #
Obser vethere commended tyre pressures. #
Adjust the tyre pressure if necessar y. #
Stop theve hicle, paying attention toroad and traf fic conditions. #
Check the tyre pressure (/ page571) and the tyres. #
When the tyre pressure is cor rect, restart the tyre pressure loss warning sy stem (/ page578).
