Driving and Operating
227
If the LDW system is not functioning
properly when lane markings are
clearly visible, cleaning the
windshield may help.
LDW alerts may occur due to tar
marks, shadows, cracks in the road,
temporary or construction lane
markings, or other road
imperfections. This is normal system
operation; the vehicle does not need
service. Turn LDW off if these
conditions continue.
Intelligent Alert Suppression
The system alerts may be
suppressed in the following
conditions:
.
Braking (obstacle avoidance).
.
Acceleration (passing another
vehicle).
.
Constant curves with great
steering wheel interaction
(driving downhill).
.
Turn signal activated.
Fuel
Fuel Additives
GM recommends the use of
ACDelco Diesel Fuel conditioner.
This will help maintain optimal
engine performance. GM does not
recommend other aftermarket diesel
additives.
In the event you refuel using
low-quality diesel, GM recommends
adding ACDelco Fuel System
Treatment Plus-Diesel to the
vehicle
’
s fuel tank. ACDelco Fuel
System Treatment Plus-Diesel can
help clean engine deposits and is
available only at your GM
dealership.
Fuel for Diesel Engines
The selection of a high-quality fuel
is important for maintaining optimum
vehicle performance. Diesel fuel
should meet or exceed the minimum
requirements in the most current
versions of the local fuel standards.
Do not use fuel with more than 15
ppm sulfur. If available, use of diesel
fuel with less sulfur is highly
recommended for better emissions.
In countries where 15 ppm or lower
sulfur is not available, do not use
diesel fuel with sulfur great than 50
ppm. In these countries only, the
vehicle is already designed to
accommodate this level of sulfur.
Do not use a diesel blend containing
more than 10% biodiesel by volume.
Caution
Use of fuel that does not comply
with the required technical
standards can lead to engine
power loss, increased wear,
or engine damage and may void
your warranty.
Some improper fuels are:
.
Diesel fuel with the addition
of gasoline.
