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.
. Using Tour mode rather than
Sport or Track modes, will result
in better Active Fuel
Management operation. See
Active Fuel Management 0169.
. For recommended shift speeds,
see Dual Clutch Transmission
0 171.

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
0 311.
This vehicle has an airbag system.
Before attempting to do your own
service work, see Servicing the
Airbag-Equipped Vehicle 072. If equipped with remote vehicle
start, open the hatch/trunk before
performing any service work to
prevent remote starting the vehicle
accidentally. See
Remote Vehicle
Start 015.
Keep a record with all parts receipts
and list the mileage and the date of
any service work performed. See
Maintenance Records 0297.
Caution
Even small amounts of
contamination can cause damage
to vehicle systems. Do not allow
contaminants to contact the fluids,
reservoir caps, or dipsticks.

Engine oils that have been
approved by GM as meeting the
dexos2 specification are marked
with the dexos2 approved logo. See
www.gmdexos.com.
GM recommends Mobil 1 engine
oils that show the dexos2
approved logo.
Caution
Failure to use the recommended
engine oil or equivalent can result
in engine damage not covered by
the vehicle warranty.
Viscosity Grade
Use SAE 0W-40 viscosity grade
engine oil. When selecting an oil of the
appropriate viscosity grade, it is
recommended to select an oil of the
correct specification. See
“Specification”
previously in this
section.
Engine Oil Additives/Engine
Oil Flushes
Do not add anything to the oil. The
recommended oils meeting the
dexos2 specification are all that is
needed for good performance and
engine protection.
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, 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 that
indicates when to change the
engine oil and filter. This is based
on a combination of factors 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.

Caution
Use of the incorrect transmission
fluid may damage the vehicle,
and the damage may not be
covered by the vehicle warranty.
Always use the correct
transmission fluid. See
Recommended Fluids and
Lubricants0295.
Change the fluid and filter at the
proper intervals. See Maintenance
Schedule 0286. Be sure to use the
correct fluid. See Recommended
Fluids and Lubricants 0295.
Dual Clutch Transmission
Fluid Life System
When to Change the Dual
Clutch Transmission Fluid
This vehicle has a computer that
indicates when to change the
transmission fluid. This is based on
a combination of factors which
include temperature and miles
driven. Based on driving conditions, the mileage at which a fluid change
is indicated can vary considerably.
For the fluid life system to work
properly, the system must be reset
every time the fluid is changed.
When the system has calculated
that fluid life has been diminished, it
indicates that a fluid change is
necessary. A CHANGE
TRANSMISSION FLUID SOON
message comes on. Change the
fluid as soon as possible within the
next 1 000 km (600 mi). Failure to
change transmission fluid at
required intervals could lead to
suboptimal transmission
performance. Your dealer has
trained service technicians who will
change the fluid and reset the
system. If the system is ever reset
accidentally, the fluid must be
changed at 72 000 km (45,000 mi)
since the last fluid change.
How to Reset the Dual Clutch
Transmission Fluid Life
System
Reset the system whenever the
transmission fluid is replaced so that
the system can calculate the next
transmission fluid change.
To reset:
1. Place the vehicle in P (Park).
2. Select the Oil & Fluid Life page under the Maintenance DIC
menu. See Driver Information
Center (DIC) 0108.
3. Press the thumbwheel under the Oil & Fluid Life page to
move to the Reset/Disable
display area. Select Reset
Transmission Fluid with the
thumbwheel scroll then press
the thumbwheel. Then press
Yes to confirm the reset.
4. When the Transmission Fluid Life System is successfully
reset, 100% Transmission Fluid
Life will be displayed.
