DRIVING AND OPERATING

AdBlue Low
As the AdBlue level drops, warnings
automatically display in the Driver
Information Centre (DIC). Select
Vehicle Information in the DIC to view
AdBlue level status. See
.
Refill the AdBlue tank at the first
opportunity after a low warning
indication. If the AdBlue tank is
empty, the vehicle may not restart.
It may take some time for the vehicle
to detect that AdBlue has been added.
If AdBlue is added in freezing
conditions, additional time may be
required to recognise the new AdBlue
level.
The AdBlue range DIC message first
displays at approximately 2400 km
(1,491 mi). This message appears
again at approximately 1750 km
(1,087 mi) of remaining range before
the AdBlue tank becomes empty.
As the fluid level nears empty, these
messages appear every time the
vehicle is started.
If the AdBlue low warnings are
ignored and the AdBlue tank becomes
empty, the DIC will display messages
that describe the action needed and
distance until vehicle restarts are
prevented.
AdBlue Quality Poor
Use only AdBlue that is GM approved,
or fluid containing the API certified or
ISO 22241 label.
AdBlue has an expiration date. If the
system detects poor quality,
or contaminated, or diluted AdBlue, a
DIC message will display along with
distance until vehicle restarts are
prevented. There will also be a
flashing warning light and chimes.
Adding fresh AdBlue to the system
may resolve the problem after driving
a short distance, depending on several
factors. If the DIC message persists,
see your dealer.
High Emission Warnings
If a problem occurs with the vehicle
emission system, chimes sound and a
DIC message displays along with
distance until vehicle restarts will be
prevented. In some cases, this
message will clear itself, indicating
that the emission system has
corrected the condition. If the DIC
message persists, see your dealer.
Automatic Transmission
The shift pattern is displayed in the
top of the gear lever. The selected gear
position will illuminate red on the
gear lever, while all others will be
displayed in white. If the gear change
is not immediate, as in very cold
conditions, the indicator on the gear
lever may flash until it is fully
engaged.
