3 Precautions for inspection and mainte-
nance
•
DEF dosing system
The DEF dosing system (pump module plus
dosing module) continues to operate for about
2 minutes after the starter switch has been put
in the “LOCK” position. Wait for at least 2 min-
utes before disconnecting the battery and elec-
trical system connectors in order to carry out an
inspection, maintenance and so on.
• Muffler
Each muffler has a built-in catalyst and ceramic
filter.
CAUTION
• Each muffler contains a catalyst and ceramic
filter, so do not kick or strike the muffler
because you may damage the catalyst and/
or the ceramic filter.
• Depending upon the way in which the vehi-
cle is used, a large amount of rust may be
generated from the exhaust pipe and the
suspension bracket, even at an early stage.
Visually inspect the muffler, and if there is
any abnormality, contact an authorized
dealer and have the vehicle inspected.
• Do not change the length or the direction of
the exhaust pipe or muffler because this may
adversely affect the exhaust gas cleaning
function. If modification is necessary, con-
sult with an authorized dealer.
• Do not remain the dosing module cover is
heavily clogged with mud.
If mud left deposited, dosing module could
not cool down, and the BlueTec
®
could not
work effectively. Clean it at regular intervals
by using a brush or something also appro-
priate.
WARNING
Do not touch the water that comes out from
the muffler. The water is weakly acidic
because of the action of the catalyst inside
the muffler. If it comes in contact with your
skin, wash it off with lots of water.
