WARNING: Exhaust leaks may

result in entry of harmful and potentially
lethal fumes into the passenger
compartment. If you smell exhaust
fumes inside your vehicle, have your
vehicle inspected immediately. Do not
drive if you smell exhaust fumes.
WARNING: Do not park or idle your
vehicle over dry leaves, dry grass or other
combustible materials. The regeneration
process creates very high exhaust gas
temperatures and the exhaust will
radiate a considerable amount of heat
during and after regeneration and after
you have switched the engine off. This is
a potential fire hazard.
Your vehicle has various emission control
components and a diesel particulate filter
that enables it to comply with applicable
exhaust emission standards. It filters
harmful diesel particulates, for example
soot from the exhaust gas.
WARNING: The normal operating
temperature of the exhaust system is
very high. Never work around or attempt
to repair any part of the exhaust system
until it has cooled. Use special care when
working around the diesel oxidation
catalytic converter or the diesel
To avoid damaging the diesel particulate
filter:
•
•
Do not crank the engine for more than
10 seconds at a time.
Do not push-start or tow-start your
vehicle. Use booster cables. See Jump
Starting the Vehicle (page 223).
particulate filter. The diesel oxidation
catalytic converter and the diesel
particulate filter heat up to very high
temperatures after only a short period
of engine operation and remain hot after
you switch the engine off.

•
Do not switch the ignition off when your
vehicle is moving.
Do not ignore warning lamps or
information messages regarding
exhaust system cleaning and
regeneration.

Your vehicle has an on-board diagnostics

an emission control system malfunction.

particulate filter. The diesel oxidation

particulate filter heat up to very high
temperatures after only a short period
of engine operation and remain hot after
you switch the engine off.
If you continue to drive your vehicle with a
warning lamp illuminated, the engine could
stop without warning. This could result in
damage not covered by the vehicle
warranty. Have your vehicle checked as
soon as possible.
The diesel particulate filter on your vehicle
requires periodic regeneration to maintain
correct operation. The emission control
system automatically carries out this
process. As soot gathers in the system it
begins to restrict the filter. The soot that
gathers inside the filter is cleaned in two
different ways, passive regeneration and
active regeneration. Both methods occur
automatically and require no actions from
the driver. During automatic regeneration,
the system cleans the diesel particulate
filter by oxidizing the soot. Cleaning
happens during normal engine operating
conditions at varying levels depending on
driving conditions.

particles. During cleaning, soot particles
are converted to harmless gasses. Once
cleaned, the diesel particulate filter
continues to trap harmful diesel particles.
The warning lamp continues to illuminate
until the automatic regeneration process
completes. Continue to drive your vehicle
in a manner to allow effective diesel
particulate filter cleaning until the warning
lamp turns off.
Failure to carry out regeneration when
required could result in a clogged diesel
particulate filter. If the diesel particulate
filter fills beyond the regeneration
threshold, the system disables the ability
to carry out regeneration. This could result
in damage not covered by the vehicle
warranty.
If you are driving your vehicle in a manner
that allows effective cleaning, a message
may appear in the information display to
indicate automatic regeneration is in
progress.
If you are not driving your vehicle in a
manner that allows effective cleaning, a
message may appear in the information
display to instruct you to drive in a manner
that allows automatic regeneration.
The automatic regeneration process is
most effective when you drive at a steady
vehicle speed of 48 km/h (30 mph) or
above for approximately 20 minutes. The
frequency and duration of the regeneration
process varies by how you drive your
vehicle, the outside air temperature and
altitude. Frequency varies between 160 km
(100 mi) and 500 km (310 mi) and each
regeneration process lasts between 10 and
20 minutes.
Where vehicle use meets any of the
following conditions:
•
•
•
Driving short distances.
Prolonged engine idling.
Frequently switching the engine on and
off.
•
High levels of acceleration and
deceleration.
Note: Changes in the engine or exhaust
sound may be heard during the regeneration
process.
Note: During regeneration at low speed or
engine idle, you could smell a hot metallic
odor and could notice a clicking metallic
sound. This is due to the high temperatures
reached during the regeneration process.
This is normal.
We recommend you assist the
regeneration process by:
•
•
Avoiding prolonged engine idling.
Drive your vehicle in a manner to allow
effective cleaning. Drive at a steady
vehicle speed of 48 km/h (30 mph) or
above for approximately 20 minutes.
If the soot load in the diesel
particulate filter reaches a
critical level, the malfunction
indicator lamp illuminates with the diesel
particulate filter warning message. A
service regeneration must be performed
to recover the particulate filter. Have your
vehicle checked as soon as possible to
prevent further damage.
