Adblue - Cadillac XT4 Owner's Manual

212 DRIVING AND OPERATING
Caution
Damage can occur to the DPF
components if the required Ultra
Low Sulphur Diesel (15 ppm
sulphur maximum) fuel and engine
oil specified in the Recommended
Fluids and Lubricants section of
this manual are not used. This
damage would not be covered by
the vehicle warranty.
Under certain conditions, such as
idling or very short trips, the
self-cleaning process has less
efficiency and cannot be completed.
To resolve this, continue driving safely
at a steady speed as close to the
posted speed limit as possible,
preferably without stopping, until the
message clears. This can take up to
30 minutes.
Warning
During DPF self cleaning or during
extended idling in P (Park), the
exhaust system and exhaust gases
are very hot. Things that burn could
Warning (Continued)
touch hot exhaust parts under the
vehicle and ignite. You or others
could be burned. Do not park,
or idle for an extended period of
time, near or over papers, leaves,
dry grass, or other things that can
burn. Keep the exhaust area clear of
material that could ignite or burn.
See Parking over Things That Burn
in the owner's manual.
Caution
Avoid extended idling because the
DPF system is not capable of
self-cleaning at idle speed. During
extended idling, monitor the
instrument cluster lights and DIC
for messages and take appropriate
action. Continued idling with the
warning light/message shown could
cause damage to the DPF, requiring
repair and possible replacement
that might not be covered by the
vehicle warranty.
During self-cleaning, there will be a
change in the exhaust sound and
engine idle speed. Along with this, a
burning smell and reduction in fuel
economy may be noticed. This is
normal.
If the vehicle is run at idle speed or
driven on very short trips with the
DPF warning message shown and the
exhaust filter is not cleaned as
required, the malfunction indicator
lamp and a DIC message will be
shown. See your dealer. Also see
Malfunction Indicator Lamp (Check
Engine Light) 0 106.
See Accessories and Modifications
0 286 if you are adding accessories or
modifying the vehicle.
