operates. Any resulting
damage would not be
covered by the vehicle
warranty. See Add-On
Electrical Equipment0360.
To start the vehicle: 1. With the Keyless Access system, the remote key
must be in the vehicle.
Press ENGINE START/
STOP with the brake pedal
applied. When the engine
begins cranking, let go of
the button. The idle speed
will go down as the engine
warms up. Do not race the
engine immediately after
starting it.
If the remote key is not in
the vehicle, if there is
interference, or if the
remote key is low, a Driver
Information Center (DIC)
message will display. See
Remote Key Operation 09.
Caution
Cranking the engine for long
periods of time, by pressing
ENGINE START/STOP
immediately after cranking
has ended, can overheat and
damage the cranking motor,
and drain the battery. Wait
at least 15 seconds between
each try, to let the cranking
motor cool down.
2. If the engine does not start after five to 10 seconds,
especially in very cold
weather (below −18 °C or
0 °F), it could be flooded
with too much gasoline.
Try pushing the
accelerator pedal all the
way to the floor and hold it
there, then press ENGINE
START/STOP for up to a
maximum of 15 seconds.
Wait at least 15 seconds
between each try, to allow
the cranking motor to cool
down. When the engine
starts, let go of the button and the accelerator. If the
vehicle starts briefly but
then stops again, do the
same thing. This clears the
extra gasoline from the
engine. Do not race the
engine immediately after
starting it. Operate the
engine and transmission
gently until the oil warms
up and lubricates all
moving parts.
Stop/Start System
This vehicle has a Stop/Start
system to shut off the engine
to help conserve fuel. It has
components designed for the
increased number of starts.
{Warning
The automatic engine Stop/
Start feature causes the
engine to shut off while the
vehicle is still on. Do not exit
the vehicle before shifting to
P (Park). The vehicle may
restart and move

GM recommends the use of
TOP TIER Detergent Gasoline
to keep the engine clean,
reduce engine deposits, and

maintain optimal vehicle
performance. Look for the
TOP TIER Logo or see
www.toptiergas.com for a list
of TOP TIER Detergent
Gasoline marketers and
applicable countries.Recommended Fuel
(2.0L L4 Turbo
Engine)
Premium unleaded gasoline
meeting ASTM specification
D4814 with a posted octane
rating (R+M)/2 of 91 or greater
is recommended. If unavailable,
unleaded gasoline with a
posted octane rating of
87 may be used, but will result
in reduced performance and
driveability. If heavy knocking
is heard when using gasoline
rated at 91 or greater, the
engine needs service.
Do not use any fuel labeled
E85 or FlexFuel. Do not use
gasoline with ethanol levels
greater than 15% by volume.
Recommended Fuel
(3.6L V6 Engine)
Regular unleaded gasoline
meeting ASTM specification
D4814 with a posted octane
rating (R+M)/2 of 87 or
greater is recommended. Do
not use gasoline with a posted
octane rating of less than 87,
as this will result in reduced
performance and driveability.
If heavy knocking is heard
when using gasoline rated at
87 or greater, the engine
needs service.
Do not use any fuel labeled

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 that 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,
ferrocene, and aniline.
These fuels can corrode
metal fuel system parts or
damage plastic and rubber
parts.
.Fuel containing metals
such as
methylcyclopentadienyl
manganese tricarbonyl(Continued)
Caution (Continued)
(MMT), which can damage
the emissions control
system and spark plugs.
.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.
Fuels in Foreign
Countries
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 0344.
Fuel Additives
TOP TIER Detergent Gasoline
is highly recommended for use
with your vehicle. If your
country does not have TOP
TIER Detergent Gasoline, add
ACDelco Fuel System Treatment Plus−Gasoline to
the vehicle’s gasoline fuel tank
at every oil change or
15 000 km (9,000 mi),
whichever occurs first. TOP
TIER Detergent Gasoline and
ACDelco Fuel System
Treatment Plus−Gasoline will
help keep your vehicle’s
engine fuel deposit free and
performing optimally.
Filling the Tank
An arrow on the fuel gauge
indicates which side of the
vehicle the fuel door is on. See

Fuel vapors and fuel fires
burn violently and can cause
injury or death.

Vehicle Care 419
GM recommends that tires,
including the spare if
equipped, be replaced after six
years, regardless of tread
wear. To identify the age of a
tire, use the tire manufacture
date, which is the last four
digits of the DOT Tire
Identification Number (TIN)
molded into one side of the
tire sidewall. The last four
digits of the TIN indicate the
tire manufactured date. The
first two digits represent the
week and the last two digits,
the year. For example, the
third week of the year 2020
would have a 4-digit DOT date
of 0320. Week 01 is the first
full week (Sunday through
Saturday) of each year.
Vehicle Storage
Tires age when stored
normally mounted on a parked
vehicle. Park a vehicle that will
be stored for at least a month
in a cool, dry, clean area away
from direct sunlight to slow
aging. This area should be freeof grease, gasoline, or other
substances that can
deteriorate rubber.
Parking for an extended
period can cause flat spots on
the tires that may result in
vibrations while driving. When
storing a vehicle for at least a
month, remove the tires or
raise the vehicle to reduce the
weight from the tires.
Buying New Tires
GM has developed and
matched specific tires for
the vehicle. The original
equipment tires installed
were designed to meet
General Motors Tire
Performance Criteria
Specification (TPC Spec)
system rating. When
replacement tires are
needed, GM strongly
recommends buying tires
with the same TPC Spec
rating.
GM's exclusive TPC Spec
system considers over a
dozen critical specifications
that impact the overall
performance of the vehicle,
including brake system
performance, ride and
handling, traction control,
and tire pressure
monitoring performance.
GM's TPC Spec number is
molded onto the tire's
sidewall near the tire size.
If the tires have an
all-season tread design, the
TPC Spec number will be
followed by MS for mud
and snow. See Tire
Sidewall Labeling
0402 for
additional information.
GM recommends replacing
worn tires in complete sets
of four. Uniform tread
depth on all tires will help
to maintain the
performance of the vehicle.
