9-44 Driving and Operating
Symbols
The system may have a feature that
lets the driver view caution symbols
on the infotainment screen while
using the RVC. The Ultrasonic Rear
Park Assist (URPA) system must
not be disabled to use the caution
symbols. The error message Rear
Parking Assist Symbols Unavailable
may display if URPA has been
disabled and the symbols have
been turned on.
The symbols appear and may cover
an object when viewing the
infotainment screen when an object
is detected by the URPA system.
To turn the symbols on or off:
1. Shift into P (Park).
2. Press the CONFIG button toenter the configure menu
options.
3. Select Display.
4. Select Rear Camera Options. 5. Select Symbols. When a
checkmark appears next to the
Symbols option, symbols will
appear.
Rear Cross Traffic Alert (RCTA)
On vehicles with the RCTA, a
warning triangle with a left or right
pointing arrow may also display on
the RVC screen to warn of traffic
coming from the left or the right.
Three beeps will also sound. This
system detects objects coming from
up to 20 m (65 ft) from the left or
right side behind the vehicle. The
RCTA system will not work properly
if ice, snow, mud, or anything else
builds up on the rear bumper
sensors.
Use caution while backing up when
towing a trailer, as the RCTA
detection zones that extend out
from the back of your vehicle do not
move further back when a trailer is
towed. On some vehicles, RCTA can be
turned on or off through the
infotainment system:
1. Shift into P (Park).
2. Press the CONFIG button to
enter the configure menu
options.
3. Select Display.
4. Select Rear Camera Options.
5. Select Rear Cross Traffic Alert. When a checkmark appears next
to the Rear Cross Traffic Alert
option, this feature will be on.
Guidelines
The RVC system may have a
guideline overlay that can help the
driver align the vehicle when
backing into a parking spot.

When the System Does Not
Seem to Work Properly
The RVC system may not work
properly or display a clear image if:
.The RVC is turned off. See
“Turning the Rear Camera
System On or Off”earlier in this
section.
.It is dark.
.The sun or the beam of
headlamps are shining directly
into the camera lens.
.Ice, snow, mud, or anything else
builds up on the camera lens.
Clean the lens, rinse it with
water, and wipe it with a soft
cloth.
.The back of the vehicle is in an
accident. The position and
mounting angle of the camera
can change or the camera can
be affected. Be sure to have the
camera and its position and
mounting angle checked at your
dealer.
Lane Departure
Warning (LDW)
If equipped, LDW may help avoid
crashes due to unintentional lane
departures. It may provide a
warning if the vehicle is crossing a
lane without using a turn signal.
LDW uses a camera sensor to
detect the lane markings. It only
operates at speeds of 56 km/h (35
mph) or greater.
When the vehicle crosses a
detected lane marking, the LDW
indicator will flash and three beeps
will sound from the left or right side,
depending on the lane departure
direction. LDW will not warn if the
turn signal is on in the departure
direction, or if a sharp maneuver
is made.
{Warning
The LDW system is an aid to help
the vehicle stay in the driving
lane. It does not steer the vehicle.
The LDW system may not:
.Provide enough time to avoid
a crash.
.Detect lane markings under
bad weather conditions or if
the windshield is dirty.
.Detect lane markings and will
not detect road edges.
.Warn that the vehicle is
crossing a lane marking if the
system does not detect the
lane marking.
If LDW only detects lane
markings on one side of the road,
it will only warn you when
departing the lane on the side
where it has detected a lane
marker. Even with LDW, always
keep your attention on the road (Continued)

Driving and Operating 9-47
Warning (Continued)
and maintain proper vehicle
position within the lane, or vehicle
damage, injury, or death could
occur. Always keep the
windshield clean and do not use
LDW in bad weather conditions.
How the System Works
The LDW camera sensor is on the
windshield ahead of the rearview
mirror.
To turn LDW on and off, press
@on
the center stack. The control
indicator will light when LDW is on.
When the vehicle is started, the
LDW indicator on the instrument
cluster will come on briefly. If LDW is on, the LDW indicator will
appear green if the system detects
a left or right lane marking while the
vehicle is traveling at 56 km/h (35
mph) or greater. If the vehicle
crosses a detected lane marking
without using the turn signal, this
indicator will change to amber and
flash. In addition, three beeps will
be sounded from the left or right
side, depending on the lane
departure direction.
When the System Does Not
Seem To Work Properly
If the LDW symbol does not appear
when the system is on and the
vehicle is traveling at least 56 km/h
(35 mph):
.The lane markings on the road
may not be seen.
.The camera sensor may be
blocked by dirt, snow, or ice.
.The windshield may be
damaged.
.The weather may be limiting
visibility.
This is normal operation; the vehicle
does not need service. Clean the
windshield.
Lane markings may not be detected
on curves, highway exit ramps,
or hills; or due to poor visibility.
If the LDW camera system does not
seem to operate properly, cleaning
the outside of the windshield in front
of the camera sensor may correct
the issue.
{Warning
LDW does not provide a warning
to help avoid a crash, unless it
detects the lane markings. LDW
may not detect the lane markings
if the camera sensor is blocked
by dirt, snow, or ice, or if the
windshield is damaged. It may
also not detect a lane on winding
or hilly roads, or in conditions that
can limit visibility such as fog,
rain, or snow, or if the headlamps

or windshield are not cleaned or
in proper condition. Keep the
windshield, headlamps, and
camera sensors clean and in
good repair.
LDW warnings may occur due to tar
marks, shadows, cracks in the road,
or other road imperfections. This is
normal system operation; the
vehicle does not need service.
Fuel
Use of the recommended fuel is an
important part of the proper
maintenance of this vehicle. When
driving in the U.S., to help keep the
engine clean and maintain optimum
vehicle performance, we
recommend using TOP TIER
Detergent Gasolines. See
www.toptiergas.com for a list of TOP
TIER Detergent Gasolines.
Recommended Fuel
For vehicles with a 2.0L engine, use
premium unleaded gasoline with a
posted octane rating of 91 or higher.
Regular unleaded gasoline rated at
87 octane or higher can be used,
but acceleration could be reduced,
and an audible knocking noise may
be heard. If the octane is less than
87, a heavy knocking noise may be
heard. If this occurs, use a gasoline
rated at 87 octane or higher as soon
as possible. Otherwise, the engine
could be damaged. If heavy
knocking is heard when using
gasoline with a higher octane rating,
the engine needs service.
For vehicles with a 2.4L engine, use
regular unleaded gasoline with a
posted octane rating of 87 or higher.
If the octane rating is less than 87,
an audible knocking noise may be
heard. If this occurs, use a gasoline
rated at 87 octane or higher as soon
as possible. If heavy knocking is

condition is caused by the type of
fuel used, repairs may not be
covered by the vehicle warranty.
Fuels in Foreign
Countries
If planning to drive in countries
outside the U.S. or Canada, the
proper fuel might be hard to find.
Check regional auto club or fuel
retail brand websites for availability
in the country where driving. Never
use leaded gasoline, fuel containing
methanol, or any other fuel not
recommended. Costly repairs
caused by use of improper fuel
would not be covered by the vehicle
warranty.
Fuel Additives
To keep fuel systems clean, TOP
TIER Detergent Gasoline is
recommended. SeeFuel on
page 9-48.
If TOP TIER Detergent Gasoline is
not available, one bottle of Fuel
System Treatment PLUS, part number 88861013, added to the fuel
tank at every engine oil change, can
help. Fuel System Treatment PLUS
is the only gasoline additive
recommended by General Motors.
It is available at your dealer.

Trailer Towing
General Towing
Information
Only use towing equipment that has
been designed for the vehicle.
Contact your dealer or trailering
dealer for assistance with preparing
the vehicle for towing a trailer. Read
the entire section before towing a
trailer.
For towing a disabled vehicle, see
Towing the Vehicle on page 10-72.
For towing the vehicle behind
another vehicle such as a motor
home, seeRecreational Vehicle
Towing on page 10-73.
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 mi), to prevent
damage to the engine, axle or
other parts.
.Then, during the first 800 km
(500 mi) 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)
but M (Manual Mode) is
recommended. See Manual
Mode on page 9-27. Use a lower
gear if the transmission shifts
too often.
.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
liftgate, trunk/hatch, or rear-most
window is open.
When towing a trailer:

Driving and Operating 9-53
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.
For more information about
Carbon Monoxide, see Engine
Exhaust on page 9-24.
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
electric brakes, start the
combination moving and then apply
the trailer brake controller by hand
to be sure the brakes work.
During the trip, check occasionally
to be sure that the load is secure
and the lamps and any trailer
brakes still work.
Towing with a Stability Control
System
When towing, the sound of the
stability control system might be
heard. The system is reacting to the
vehicle movement caused by the
trailer, which mainly occurs during
cornering. This is normal when
towing heavier trailers.
Following Distance
Stay at least twice as far behind the
vehicle ahead as you would when
driving the vehicle without a trailer.
This can help to avoid situations
that require heavy braking and
sudden turns.
Passing
More passing distance is needed
when towing a trailer. Because the
rig is longer, it is necessary to go
farther beyond the passed vehicle
before returning to the lane.
Backing Up
Hold the bottom of the steering
wheel with one hand. To move the
trailer to the left, move your hand to
the left. To move the trailer to the
right, move your hand to the right.
Always back up slowly and,
if possible, have someone
guide you.

9-54 Driving and Operating
Making Turns
{Caution
Making very sharp turns while
trailering could cause the trailer to
come in contact with the vehicle.
The vehicle could be damaged.
Avoid making very sharp turns
while trailering.
When turning with a trailer, make
wider turns than normal so the
trailer will not strike soft shoulders,
curbs, road signs, trees or other
objects. Use the turn signal well in
advance and avoid jerky or sudden
maneuvers.
Turn Signals When Towing a
Trailer
The turn signal indicators on the
instrument cluster flash whenever
signaling a turn or lane change.
Properly hooked up, the trailer lamps also flash, telling other
drivers the vehicle is turning,
changing lanes or stopping.
When towing a trailer, the arrows on
the instrument cluster flash for turns
even if the bulbs on the trailer are
burned out. Check occasionally to
be sure the trailer bulbs are still
working.
Driving on Grades
Reduce speed and shift to a lower
gear before starting down a long or
steep downgrade. If the
transmission is not shifted down, the
brakes might have to be used so
much that they would get hot and no
longer work well.
The vehicle can tow in D (Drive).
Use a lower gear if the transmission
shifts too often.
When towing at high altitude on
steep uphill grades, engine coolant
boils at a lower temperature than at
normal altitudes. If the engine is
turned off immediately after towing
at high altitude on steep uphillgrades, the vehicle could show
signs similar to engine overheating.
To avoid this, let the engine run
while parked, preferably on level
ground, with the transmission in
P (Park) for a few minutes before
turning the engine off. If the
overheat warning comes on, see
Engine Overheating on page 10-19.
Parking on Hills
{Warning
Parking the vehicle on a hill with
the trailer attached can be
dangerous. If something goes
wrong, the rig could start to move.
People can be injured, and both
the vehicle and the trailer can be
damaged. When possible, always
park the rig on a flat surface.
