Driving for Better Fuel Economy
Driving habits can affect fuel mileage. Here
are some driving tips to get the best fuel
economy possible:
.Set the climate controls to the desired
temperature after the engine is started,
or turn them off when not required.
.Avoid fast starts and accelerate smoothly.
.Brake gradually and avoid abrupt stops.
.Avoid idling the engine for long periods
of time.
.When road and weather conditions are
appropriate, use cruise control.
.Always follow posted speed limits or
drive more slowly when conditions
require.
.Keep vehicle tires properly inflated.
.Combine several trips into a single trip.
.Replace the vehicle's tires with the same
TPC Spec number molded into the tire's
sidewall near the size.
.Follow recommended scheduled
maintenance.
Distracted Driving
Distraction comes in many forms and can
take your focus from the task of driving.
Exercise good judgment and do not let other
activities divert your attention away from
the road. Many local governments have
enacted laws regarding driver distraction.
Become familiar with the local laws in
your area.
To avoid distracted driving, keep your eyes
on the road, keep your hands on the
steering wheel, and focus your attention on
driving.
.Do not use a phone in demanding driving
situations. Use a hands-free method to
place or receive necessary phone calls.
.Watch the road. Do not read, take notes,
or look up information on phones or
other electronic devices.
.Designate a front seat passenger to
handle potential distractions.
.Become familiar with vehicle features
before driving, such as programming
favorite radio stations and adjusting
climate control and seat settings. Program
all trip information into any navigation
device prior to driving.
.Wait until the vehicle is parked to
retrieve items that have fallen to the
floor.
.Stop or park the vehicle to tend to
children.
.Keep pets in an appropriate carrier or
restraint.
.Avoid stressful conversations while
driving, whether with a passenger or on a
cell phone.
{Warning
Taking your eyes off the road too long or
too often could cause a crash resulting in
injury or death. Focus your attention on
driving.
Refer to the infotainment section for more
information on using that system and the
navigation system, if equipped, including
pairing and using a cell phone.
Defensive Driving
Defensive driving means “always expect the
unexpected.” The first step in driving
defensively is to wear the seat belt. See
Seat Belts 040.

Doing Your Own Service Work
{Warning
It can be dangerous to work on your
vehicle if you do not have the proper
knowledge, service manual, tools,
or parts. Always follow owner’s manual
procedures and consult the service
manual for your vehicle before doing any
service work.
If doing some of your own service work, use
the proper service manual. It tells you much
more about how to service the vehicle than
this manual can. To order the proper service
manual, see Publication Ordering
Information 0353. This vehicle has an airbag system. Before
attempting to do your own service work,
see
Servicing the Airbag-Equipped Vehicle
0 55.
If equipped with remote vehicle start, open
the hood before performing any service
work to prevent remote starting the vehicle
accidentally. See Remote Vehicle Start 013.
Keep a record with all parts receipts and list
the mileage and the date of any service
work performed. See Maintenance Records
0 341.
Caution
Even small amounts of contamination can
cause damage to vehicle systems. Do not
allow contaminants to contact the fluids,
reservoir caps, or dipsticks.
Hood
{Warning
For vehicles with auto engine stop/start,
turn the vehicle off before opening the
hood. If the vehicle is on, the engine will
start when the hood is opened. You or
others could be injured.
{Warning
Components under the hood can get hot
from running the engine. To help avoid
the risk of burning unprotected skin,
never touch these components until they
have cooled, and always use a glove or
towel to avoid direct skin contact.
Clear any snow from the hood before
opening.

264 Vehicle Care
Engine oil system flushes are not
recommended and could cause engine
damage not covered by the vehicle
warranty.
What to Do with Used Oil
Used engine oil contains certain elements
that can be unhealthy for your skin and
could even cause cancer. Do not let used oil
stay on your skin for very long. Clean your
skin and nails with soap and water, or a
good hand cleaner. Wash or properly
dispose of clothing or rags containing used
engine oil. See the manufacturer's warnings
about the use and disposal of oil products.
Used oil can be a threat to the environment.
If you change your own oil, be sure to drain
all the oil from the filter before disposal.
Never dispose of oil by putting it in the
trash or pouring it on the ground, into
sewers, or into streams or bodies of water.
Recycle it by taking it to a place that
collects used oil.
Engine Oil Life System
When to Change Engine Oil
This vehicle has a computer system that
indicates when to change the engine oil and
filter. This is based on a combination offactors which include engine revolutions,
engine temperature, and miles driven. Based
on driving conditions, the mileage at which
an oil change is indicated can vary
considerably. For the oil life system to work
properly, the system must be reset every
time the oil is changed.
When the system has calculated that oil life
has been diminished, it indicates that an oil
change is necessary. A CHANGE ENGINE OIL
SOON message comes on. Change the oil as
soon as possible within the next 1 000 km
(600 mi). It is possible that, if driving under
the best conditions, the oil life system may
indicate that an oil change is not necessary
for up to a year. The engine oil and filter
must be changed at least once a year and,
at this time, the system must be reset. Your
dealer has trained service people who will
perform this work and reset the system.
It is also important to check the oil regularly
over the course of an oil drain interval and
keep it at the proper level.
If the system is ever reset accidentally, the
oil must be changed at 5 000 km (3,000 mi)
since the last oil change. Remember to reset
the oil life system whenever the oil is
changed.
How to Reset the Engine Oil Life System
Reset the system whenever the engine oil is
changed so that the system can calculate
the next engine oil change. To reset the
system:
1. Display REMAINING OIL LIFE on the DIC menu. See Driver Information Center
(DIC) (Base and Midlevel) 0100 or
Driver Information Center (DIC) (Uplevel)
0 105.
2. Press and hold
Vfor several seconds
while the Oil Life display is active to
reset the Oil Life system.
3. REMAINING OIL LIFE 100% will be displayed when the oil life system is
successfully reset.
The oil life system can also be reset as
follows: 1. Place the ignition in Service Mode. See Ignition Positions 0199.
2. Display REMAINING OIL LIFE on the DIC menu. See Driver Information Center
(DIC) (Base and Midlevel) 0100 or
Driver Information Center (DIC) (Uplevel)
0 105.
3. Fully press and release the accelerator pedal three times within five seconds.

Step One first.
STEP THREE —U.S. Owners : Both General
Motors and your dealer are committed to
making sure you are completely satisfied
with your new vehicle. However, if you

Program to enforce your rights.
The BBB Auto Line Program is an
out-of-court program administered by the
BBB National Programs, Inc. to settle automotive disputes regarding vehicle
repairs or the interpretation of the New
Vehicle Limited Warranty. Although you
may be required to resort to this informal
dispute resolution program prior to filing a
court action, use of the program is free of
charge and your case will generally be heard
within 40 days. If you do not agree with the
decision given in your case, you may reject
it and proceed with any other venue for
relief available to you.

Customer Information 351
If the vehicle cannot be scheduled into the
service department immediately, keep
driving it until it can be scheduled for
service, unless, of course, the problem is
safety related. If it is, please call your
dealership, let them know this, and ask for
instructions.
If your dealer requests you to bring the
vehicle for service, you are urged to do so
as early in the work day as possible to
allow for same-day repair.
Courtesy Transportation Program
To enhance your ownership experience, we
and our participating dealers are proud to
offer Courtesy Transportation, a customer
support program for vehicles with the
Bumper-to-Bumper (Base Warranty Coverage
period in Canada), extended powertrain,
and/or hybrid-specific warranties in both the
U.S. and Canada.
Several Courtesy Transportation options are
available to assist in reducing inconvenience
when warranty repairs are required.
Courtesy Transportation is not a part of the
New Vehicle Limited Warranty. A separate
manual entitled“Limited Warranty and Owner Assistance Information”
furnished
with each new vehicle provides detailed
warranty coverage information.
Transportation Options
Warranty service can generally be
completed while you wait. However, if you
are unable to do so, your dealer may offer
the following transportation options:
Shuttle Service
This includes one-way or round-trip shuttle
service within reasonable time and distance
parameters of your dealer's area.
Public Transportation or Fuel Reimbursement
If overnight warranty repairs are needed,
and public transportation is used, the
expense must be supported by original
receipts and within the maximum amount
allowed by GM. If U.S. customers arrange
their own transportation, limited
reimbursement for reasonable fuel expenses
may be available. Claim amounts should
reflect actual costs and be supported by
original receipts. See your dealer for
information. Courtesy Rental Vehicle
For an overnight warranty repair, the dealer
may provide an available courtesy rental
vehicle or provide for reimbursement of a
rental vehicle. Reimbursement is limited and
must be supported by original receipts as
well as a signed and completed rental
agreement and meet state/provincial, local,
and rental vehicle provider requirements.
Requirements vary and may include
minimum age requirements, insurance
coverage, credit card, etc. Additional fees
such as fuel, rental vehicle insurance, taxes,
levies, usage fees, excessive mileage,
or rental usage beyond the completion of
the repair are also your responsibility.
It may not be possible to provide a like
vehicle as a courtesy rental.
Additional Program Information
All program options, such as shuttle service,
may not be available at every dealer.
Contact your dealer for specific availability.
General Motors reserves the right to
unilaterally modify, change, or discontinue
Courtesy Transportation at any time and to
resolve all questions of claim eligibility
pursuant to the terms and conditions
described herein at its sole discretion.
