Diesel Exhaust Fluid; Roadside Assistance Program - Chevrolet 2015 Cruze Owner's Manual

1-22 In Brief

Diesel Exhaust Fluid

Diesel Exhaust Fluid (DEF) is used
with diesel engines to reduce the
amount of regulated emissions
produced. The DEF system must be
maintained for the vehicle to run
properly. It is normal to hear the
DEF system purge fluid back into
the tank after the vehicle is shut off.
Locating Diesel Exhaust Fluid
DEF can be purchased at a
Chevrolet dealer. It can also be
purchased at authorized vehicle
dealerships. Additionally, some
diesel fueling stations or retailers
may have DEF for purchase. For
vehicles with an active OnStar
subscription, OnStar can help to
locate a DEF retailer. See
Customer Assistance Offices in
the owner manual for phone
numbers to assist you in contacting
a GM dealer. See Recommended
Fluids and Lubricants on
page 11-12.
As the DEF tank becomes low on
fluid, warnings begin with
approximately
1 600 km (1,000 miles) of remaining
range. These warnings will increase
in intensity as the tank becomes
empty. Once the tank is empty, the
vehicle speed will be limited. If there
is an issue with the quality of the
fluid or the exhaust fluid system,
warnings will be displayed in the
Driver Information Center (DIC).
