174 Driving and Operating
Operating Modes
The transmission may operate in a
lower gear than normal to improve
vehicle performance. The engine
speed may be higher and there may
be an increase in noise during the
following conditions:
.When climbing a grade.
. When driving downhill.
. When driving in hot
temperatures or at high altitude.
Manual Mode
Electronic Range Select
(ERS) Mode
ERS or manual mode allows for the
selection of the range of gear
positions. Use this mode when
driving downhill or towing a trailer to
limit the top gear and vehicle speed.
The shift position indicator within the
Driver Information Center (DIC) will
display a number next to the M
indicating the highest available gear
under manual mode and the driving
conditions when manual mode was
selected. To use this feature:
1. Move the shift lever to M (Manual Mode).
2. Press the plus/minus button on the shift lever, to increase or
decrease the gear range
available.
When shifting to M (Manual Mode),
the transmission will shift to a preset
lower gear range. For this preset
range, the highest gear available is
displayed next to the M in the DIC.
See Driver Information Center (DIC)
0 115 for more information. All gears
below that number are available to
use. For example, when 4 (Fourth)
is shown next to the M, 1 (First)
through 4 (Fourth) gears are shifted
automatically. To shift to 5 (Fifth)
gear, press the + (Plus) button or
shift into D (Drive).
M (Manual Mode) will prevent
shifting to a lower gear range if the
engine speed is too high. If vehicle
speed is not reduced within the time
allowed, the lower gear range shift
will not be completed. Slow the vehicle, then press the
−(Minus)
button to the desired lower gear
range.
While using the ERS, cruise control
can be used.
Fuel Economy Mode
Vehicles with a 2.4L engine have a
Fuel Economy Mode. When
engaged, Fuel Economy Mode can
improve the vehicle's fuel economy.

sensitive.
. The vehicle's computer will more
aggressively shut off fuel to the
engine under deceleration.
. The engine idle speed will be
lower.
. Driving performance is more
conservative.
. The climate controls may take
longer to heat or cool the cabin.
. The rear defogger will stay on
for shorter periods of time.Drive Systems
All-Wheel Drive
Vehicles with this feature transfer
engine power, as required, to all
four wheels. It is fully automatic, and
adjusts itself as needed for road
conditions.
When using a compact spare tire on
an AWD vehicle, the system
automatically detects the compact
spare and reduces AWD
performance to protect the system.
To restore full AWD operation and
prevent excessive wear on the
system, replace the compact spare
with a full-size tire as soon as
possible. See Compact Spare
Tire 0262.
Brakes
Antilock Brake
System (ABS)
This vehicle has an Antilock Brake
System (ABS), an advanced
electronic braking system that helps
prevent a braking skid.
When the vehicle begins to drive
away, ABS checks itself.
A momentary motor or clicking noise
may be heard while this test is going
on, and it may even be noticed that
the brake pedal moves a little. This
is normal.
If there is a problem with ABS, this
warning light stays on. See Antilock
Brake System (ABS) Warning
Light 0110.

Driving Characteristics
and Towing Tips
Driving with a Trailer
When towing a trailer:
.
Become familiar with the state
and local laws that apply
specifically to trailer towing. .
Do not tow a trailer during the
first 800 km (500 miles), to
prevent damage to the engine,
axle or other parts.
. Then, during the first 800 km
(500 miles) trailer towing, do not
drive over 80 km/h (50 mph) and
do not make starts at full throttle.
. The vehicle can tow in D (Drive).
Use a lower gear if the
transmission shifts too often.
. Do not use the Fuel Economy
Mode when towing.
. Turn off Park Assist when
towing.
{Warning
When towing a trailer, exhaust
gases may collect at the rear of
the vehicle and enter if the

(Continued)
Warning (Continued)
.Do not drive with the
liftgate, trunk/hatch,
or rear-most window open.
. Fully open the air outlets on
or under the instrument
panel.
. Also adjust the climate
control system to a setting
that brings in only outside
air. See “Climate Control
Systems” in the Index.

monoxide, see Engine
Exhaust 0171.
Towing a trailer requires a certain
amount of experience. The
combination you are driving is
longer and not as responsive as the
vehicle itself. Get acquainted with
the handling and braking of the rig
before setting out for the open road.
Before starting, check all trailer hitch
parts and attachments, safety
chains, electrical connectors, lamps,
tires and mirrors. If the trailer has

installed and the sensor
matching process is performed
successfully. See your dealer for
service.
. Replacement tires or wheels do
not match the original equipment
tires or wheels. Tires and wheels
other than those recommended
could prevent the TPMS from
functioning properly. See Buying
New Tires 0250.
. Operating electronic devices or
being near facilities using radio
wave frequencies similar to the
TPMS could cause the TPMS
sensors to malfunction.
If the TPMS is not functioning
properly, it cannot detect or signal a
low tire condition. See your dealer
for service if the TPMS malfunction
light and DIC message comes on
and stays on.
TPMS Sensor Matching
Process
Each TPMS sensor has a unique
identification code. The identification
code needs to be matched to a new
tire/wheel position after rotating the tires or replacing one or more of the
TPMS sensors. The TPMS sensor
matching process should also be
performed after replacing a spare
tire with a road tire containing the
TPMS sensor. The malfunction light
and the DIC message should go off
at the next ignition cycle. The
sensors are matched to the tire/
wheel positions, using a TPMS
relearn tool, in the following order:
driver side front tire, passenger side
front tire, passenger side rear tire,
and driver side rear. See your
dealer for service or to purchase a
relearn tool. A TPMS relearn tool
can also be purchased. See Tire
Pressure Monitor Sensor Activation
Tool at
www.gmtoolsandequipment.com or
call 1-800-GM TOOLS
(1-800-468-6657).
There are two minutes to match the
first tire/wheel position, and
five minutes overall to match all four
tire/wheel positions. If it takes
longer, the matching process stops
and must be restarted.
The TPMS sensor matching
process is:
1. Set the parking brake.
2. Turn the ignition to ON/RUN with the engine off.
3. Use the MENU button to select the Vehicle Information Menu
in the Driver Information Center
(DIC). Use the arrow keys to
scroll to the Tire Pressure
screen.
4. Press the SET/CLR button to begin the sensor matching
process.
A message requesting
acceptance of the process
should display.
5. Press the SET/CLR button again to confirm the selection.
The horn sounds twice to
signal the receiver is in relearn
mode and the TIRE
LEARNING ACTIVE message
displays on the DIC screen.
6. Start with the driver side front tire.

Managing the Vehicle Damage
Repair Process
In the event that the vehicle requires
damage repairs, GM recommends
that you take an active role in its
repair. If you have a pre-determined
repair facility of choice, take the
vehicle there, or have it towed there.
Specify to the facility that any
required replacement collision parts
be original equipment parts, either
new Genuine GM parts or recycled original GM parts. Remember,
recycled parts will not be covered by
the GM vehicle warranty.
Insurance pays the bill for the repair,
but you must live with the repair.
Depending on your policy limits,
your insurance company may
initially value the repair using
aftermarket parts. Discuss this with
the repair professional, and insist on
Genuine GM parts. Remember,
if the vehicle is leased, you may be
obligated to have the vehicle
repaired with Genuine GM parts,
even if your insurance coverage
does not pay the full cost.
If another party's insurance
company is paying for the repairs,
you are not obligated to accept a
repair valuation based on that
insurance company's collision policy
repair limits, as you have no
contractual limits with that company.
In such cases, you can have control
of the repair and parts choices as
long as the cost stays within
reasonable limits.
