When the System Does Not
Seem to Work Properly
The system performance may be
affected by:
.Close vehicles ahead.
. Sudden lighting changes, such
as when driving through tunnels.
. Banked roads.
. Roads with poor lane markings,
such as two-lane roads.
If the LKA system is not functioning
properly when lane markings are
clearly visible, cleaning the
windshield may help. A system unavailable message may
display if the camera is blocked.
The LKA system does not need
service.
LKA assistance and/or 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 LKA off if these
conditions continue.
Fuel
Fuel (Gasoline)
GM recommends the use of TOP
TIER detergent gasoline to keep the
engine cleaner and reduce engine
deposits. See www.toptiergas.com
for a list of TOP TIER detergent
gasoline marketers and applicable
countries.
Do not use any fuel labeled E85 or
FlexFuel. Do not use gasoline with
ethanol levels greater than 15% by

For the LYX 1.5L L4 turbo engine,
use regular unleaded gasoline
meeting ASTM specification D4814
with a posted octane rating of 87 or
higher. Do not use gasoline with a
posted octane rating of less than 87,
as this may cause engine knock and
will lower fuel economy.
For the LTG 2.0L L4 turbo engine,
premium unleaded gasoline meeting
ASTM specification D4814 with a
posted octane rating of 93 is highly
recommended for best performance
and fuel economy. Unleaded
gasoline with an octane rated as low
as 87 can be used. Using unleaded
gasoline rated below 93 octane,
however, will lead to reduced
acceleration and fuel economy.
If knocking occurs, use a gasoline
rated at 93 octane as soon as
possible, otherwise, the engine
could be damaged. If heavy
knocking is heard when using
gasoline with a 93 octane rating, the
engine needs service.Prohibited Fuels
Caution
Do not use fuels with any of the
following conditions; doing so
may damage the vehicle and void
its warranty:
. For vehicles which are not
FlexFuel, fuel labeled
greater than 15% ethanol by
volume, such as mid-level
ethanol blends (16 –50%
ethanol), E85, or FlexFuel.
. Fuel with any amount of
methanol, methylal, and
aniline. These fuels can
corrode metal fuel system
parts or damage plastic and
rubber parts.
. Fuel containing metals such
as methylcyclopentadienyl
manganese tricarbonyl
(MMT), which can damage
the emissions control
system and spark plugs.
(Continued)
Caution (Continued)
.Fuel with a posted octane
rating of less than the
recommended fuel. Using
this fuel will lower fuel
economy and performance,
and may decrease the life of
the emissions catalyst.
California Fuel
Requirements (Gasoline)
If the vehicle is certified to meet
California Emissions Standards, it is
designed to operate on fuels that
meet California specifications. See
the underhood emission control
label. If this fuel is not available in
states adopting California Emissions
Standards, the vehicle will operate
satisfactorily on fuels meeting
federal specifications, but emission
control system performance may be
affected. The malfunction indicator
lamp could turn on and the vehicle
may not pass a smog-check test.

dealer for diagnosis. If it is
determined that the condition is
caused by the type of fuel used,
repairs may not be covered by the
vehicle warranty.
Fuels in Foreign
Countries (Gasoline)
The U.S., Canada, and Mexico post
fuel octane ratings in anti-knock
index (AKI). For fuel not to use in a
foreign country, see“Prohibited
Fuels” inFuel (Gasoline) 0256.
Fuel Additives (Gasoline)
To keep fuel systems clean, TOP
TIER detergent gasoline is
recommended. See Fuel (Gasoline)
0 256.
If TOP TIER detergent gasoline is
not available, one bottle of GM Fuel
System Treatment Cleaner added to
the fuel tank at every engine oil
change, can help. GM Fuel System
Treatment Cleaner is the only gasoline additive recommended by
General Motors. It is available at
your dealer.
Fuel for Diesel Engines
The selection of a high quality fuel
is important for maintaining optimum
performance. Do not use diesel fuel
with more than 15 ppm sulfur
content. Do not use a diesel blend
containing more than 20% biodiesel
by volume. Both diesel and
biodiesel blends must meet all the
requirements as defined in the most
current versions of the local fuel
standards. See the recommended
fuels under
What Fuel to Use in the
U.S. (Diesel) 0259 andWhat Fuel
to Use in Canada and Mexico
(Diesel) 0260.
Caution
Engine damage may occur if
recommended fuels are not used,
which may void the vehicle
warranty. Some improper
fuels are:
. Diesel fuel with the addition
of gasoline.
. Diesel fuel mixed with
engine oil or automatic
transmission fluid.
. Triglyceride fuels, such as
raw vegetable oil or animal
fat, in any form, including
with blends of diesel or
biodiesel.
. Marine diesel fuel and
fuel oils.
. Diesel-water emulsions,
such as Aquazole.

Caution (Continued)
.Aftermarket diesel fuel
additives, which contain
alcohols, organo-metallic
additives, or water
emulsifiers.
. Diesel fuel with sulfur
greater than 15 ppm.
. Diesel-biodiesel blends not
within the required
specification.
Some conditions, such as dirty fuel,
may decrease fuel filter life and a
CHANGE FUEL FILTER message
may come on in the Driver
Information Center (DIC).
What Fuel to Use in the
U.S. (Diesel)
Use of diesel fuel with ultra low
sulfur content (15 ppm, maximum) is
required. Look for service station
fuel dispensers with this label in
green:
The diesel fuel must meet ASTM
International specification D 975,
Grades No. 2-D or No. 1-D S15,
also known as Ultra Low Sulfur
Diesel. Contact a fuel supplier or
fueling station with any questions.
Diesel Fuel Grades
For best results use No. 2-D diesel
fuel year-round because it is
blended for seasonal temperature
differences, both above and below
freezing conditions. No. 1-D diesel
also meeting ASTM International
D975 fuel can be used in very cold
temperatures (below −18 °C or
0 °F); however, it will reduce power
and fuel economy. Avoid using No. 1-D diesel fuel in warm or hot
climates. It can result in stalling,
poor starting when the engine is hot,
and damage to the fuel injection
system.
Premium Diesel Fuel
Premium Diesel Fuel (FQP-1A)
corresponds to the Engine
Manufacturers Association (EMA)
Recommended Guideline. It may
provide less noise, better starting,
and better vehicle performance, but
is not required.
Biodiesel Blends
Retail pumps dispensing blends
containing up to 5% biodiesel (B5)
are not required to be labeled with
the concentration of biodiesel.
Blends up to B5 must meet ASTM
D975 (Grades No. 2-D or No. 1-D
S15 Ultra Low Sulfur Diesel). When
refueling with a biodiesel blend
above B5, one of the following
labels should appear on the
dispenser:

Chevrolet Equinox Owner Manual (GMNA-Localizing-U.S./Canada/Mexico-
10446639) - 2018 - CRC - 8/18/17
260 Driving and Operating
Blends containing more than 5%
and up to 20% biodiesel must meet
ASTM specification D7467
(Biodiesel blend, B6 - B20) and are
labeled with an orange or bluepump label. To reduce the risk of
poor quality fuel, purchase biodiesel
blends from a fuel supplier or fueling
station that sells BQ-9000 certified
biodiesel. See www.bq-9000.org for
a list of certified marketers. See
Biodiesel
0261.
What Fuel to Use in
Canada and Mexico
(Diesel)
What Fuel to Use in Canada
Use of diesel fuel with ultra low
sulfur content (15 ppm, maximum) is
required. Use diesel fuel that meets
the CAN/CGSB-3.517 specification
in Canada. Contact a fuel supplier
with questions about fuel.
Caution
Use of diesel fuel other than Ultra
Low Sulfur Diesel (15 ppm sulfur
maximum) will cause damage to
the exhaust after-treatment
system. This damage would not
(Continued)
Caution (Continued)
be covered by the vehicle
warranty. Do not use marine,
locomotive, or boiler distillate fuel
since it may contain higher sulfur
levels.
Diesel Fuel Types
For best results use Ultra Low
Sulfur Type B Diesel. This fuel is
blended for seasonal changes. In
extreme cold temperatures (below
−18 °C or 0 °F) Ultra Low Sulfur
Type A Diesel fuel can be used, but
it may cause power and fuel
economy losses. Avoid using Type
A Diesel fuel in warm or hot
climates. Doing so can result in
stalling, poor starting when the
engine is hot, and damage to the
fuel injection system.
Premium Diesel Fuel
If available, premium diesel fuel
(FQP-1A) corresponding to the
Engine Manufacturers Association

(EMA) Recommended Guideline
could provide better starting and
vehicle performance with less noise.
Biodiesel Blends in Canada
Biodiesel blends that meet the
CAN/CGSB-3.522 specifications up
to 20% (B20) can be used. Avoid
the use of biodiesel blends above
20%, as they may damage the
engine and fuel system. For detailed
information on the use of biodiesel,
seeBiodiesel 0261.
What Fuel to Use in Mexico
Use diesel fuel specification
NOM-086 Pemex UBA, which meets
the Ultra Low Sulfur Diesel fuel
requirement of 15 ppm sulfur
maximum. This fuel is not available
in all regions of Mexico.
Caution
Use of diesel fuel other than Ultra
Low Sulfur Diesel (15 ppm sulfur
maximum) will cause damage to
the exhaust after-treatment
(Continued)
Caution (Continued)
system. This damage would not
be covered by the vehicle
warranty. Do not use marine,
locomotive, or boiler distillate fuel
since it may contain higher sulfur
levels.
Biodiesel
Biodiesel is a renewable fuel
produced from vegetable oils or
animal fats that have been
chemically modified to make it
compatible with diesel fuel.
Caution
Do not use home-made biodiesel
or home test kits because the
quality cannot be verified by
approved scientific methods. Do
not use raw vegetable oil or other
unmodified bio-oils, fats,
or blends of vegetable oil with
diesel. They could damage the(Continued)
Caution (Continued)
fuel system and engine, and
damages would not be covered
by the vehicle warranty.
Caution
Do not use blends containing
more than 20% biodiesel. Any
engine, fuel system, or exhaust
after-treatment system damage
would not be covered by the
vehicle warranty.
Biodiesel fuel quality degrades with
time and exposure to high
temperature quicker than Ultra Low
Sulfur Diesel fuel. More frequent
refueling provides the best
opportunity to have a supply of fresh
fuel. Storage at hot ambient
temperatures will accelerate
biodiesel degradation.
Owners who use very little fuel,
or who have vehicles stored for
extended periods of time, should

Chevrolet Equinox Owner Manual (GMNA-Localizing-U.S./Canada/Mexico-
10446639) - 2018 - CRC - 8/18/17
262 Driving and Operating
avoid the use of biodiesel blended
fuels above 5% by volume. When
vehicles are stored for longer than
one month, they should be run out
of biodiesel to below one-quarter
tank, refueled with Ultra Low Sulfur
Diesel fuel, and driven at least
32 km (20 mi) before storage.
At temperatures below 0 °C (32 °F),
it is recommended to switch to Ultra
Low Sulfur Diesel fuel with no
biodiesel content, or to blends with
biodiesel containing less than 5% by
volume. At these extreme cold
temperatures, biodiesel blends
higher than 5% by volume may
cause fuel filter plugging and
system gelling, which can lead to
vehicle operability problems.
Fuels improperly blended for cold
temperature operation may result in
restricted fuel filters and degraded
vehicle performance. GM diesel
vehicles are equipped with a fuel
heating system to provide an extra
level of protection against filter
plugging from gelling or waxing of
conventional diesel fuel and
biodiesel blends. If the operatingtemperature is far below the
temperature at which gelling or
waxing of the fuel occurs, the
system cannot prevent all cases of
filter plugging.
If the vehicle experiences a fuel
filter restriction, the on-board
monitoring system will alert the
driver that the fuel filter requires
service. The fuel filter, however, will
not prevent all damage caused by
poor quality biodiesel.
Cold Weather Operation
(Diesel)
In cold weather, the fuel filter may
become clogged by wax naturally
present in the fuel. To unclog it,
move the vehicle to a warm garage
area and allow the filter to warm up.
The fuel filter may need to be
replaced. See
Fuel Filter
Replacement (Diesel) 0266.
At temperatures below 0 °C (32 °F),
it is recommended to avoid using
biodiesel blends above 5% blend.
This blend may cause fuel filter
plugging, system gelling, and freezing that may affect vehicle
starting. You may need to turn the
ignition on and off a few times
before the vehicle will start. Also,
idle the vehicle for a couple of
minutes before accelerating.
Water in Fuel (Diesel)
Improper fuel tank inspection or
cleaning, or contaminated fuel from
suppliers, can cause water to be
pumped into the fuel tank along with
the diesel fuel. If a WATER IN FUEL
- CONTACT SERVICE message
displays, the water must be drained
immediately.
{Warning
Diesel fuel containing water is still
combustible. You or others could
be burned. If the fuel needs to be
drained, keep sparks, flames, and
smoking materials away from the
mixture.

Caution
Water in the diesel fuel can
corrode internal components of
the fuel system and lead to
severe damage. It can also
support fungus or bacteria
growth, which can damage the
fuel system and fuel operated
heater (FOH) (if equipped). Even
with a diesel fuel biocide, the fuel
system may still need to be
cleaned. Your dealer can advise
of the appropriate solution.
If the fuel tank needs to be
purged to remove water, see your
dealer or a qualified technician.
Improper purging can damage the
fuel system and block the FOH.As an added precaution, drain the
diesel fuel filter of residual water at
every engine oil change. If the
