highe r speed once the engine coolant has warmed up s ufficient ly .
Th e air condi tioner tempo rari ly swi tches off when yo u drive off from
a standstill using full throttle to save engine power.
Th e comp resso r also switches off if the coolant temperature is too
high so that the engine can be adeq uate ly coo led unde r extreme
loads.
Air pollutants filter
Th e a ir po llutants filter (a combined pa rticle filte r and activated cha r­
coa l f il ter) reduces or elim inates outs ide a ir pollution (dus t, or

A cold engine may sound loud after it has been started . Th is is due to

a need for concern.
If the engine does not start immediately, stop try ing after 10 seconds
and then try to restart the engine about 30 seconds later .
Glow plug system*
Diesel engines are equipped with a glow p lug system whose
preheating t ime is con trolled by the coo la nt and outs ide tempera­

immediately af ter the glow p lug ind icator light
sw itches off .
Th e g low pl ug indica tor light w ill only ill uminate fo r approximately 1

To start the diesel engine after the fuel tank has
been run dry
If the fue l tank was run complete ly dry, the start ing process after
refueling with diesel fuel can take longe r than usual -up to one
minute. This is because the fuel system first has to be vented of air
wh ile starting. _,.
