The rear window wiper/washer will not
operate if the liftgate is open or ajar. If the
liftgate is opened while the rear wiper is on,
the wiper returns to the parked position and
stops.
See“Rear Camera Washer” later in this
section.
Rear Wiper Arm Assembly Protection
When using an automatic car wash, move
the rear wiper control to OFF to disable the
rear wiper. In some vehicles, if the
transmission is in N (Neutral) and the
vehicle speed is very slow, the rear wiper
will automatically park under the rear
spoiler.
The wiper operations return to normal when
the transmission is no longer in N (Neutral)
or the vehicle speed has increased.
Auto Wipe in Reverse Gear
If the rear wiper control is off, the rear
wiper will automatically operate
continuously when the transmission is in
R (Reverse), and the front windshield wiper
is performing low or high speed wipes.
If the rear wiper control is off, the
transmission is in R (Reverse), and the front windshield wiper is performing INT wipes,
then the rear wiper automatically performs
INT wipes.
This feature can be turned on or off. See
“Auto Wipe in Reverse Gear”
under Settings
> Vehicle > Comfort and Convenience > Auto
Wipe in Reverse Gear.
The windshield washer reservoir is used for
the windshield, rear window, and rear mirror
camera, if equipped. See Rear Camera Mirror
0 29. Check the fluid level in the reservoir if
either washer is not working. See Washer
Fluid 0334.
Rear Camera Washer
If equipped, turn the windshield wiper band
fully upward or downward to spray washer
fluid on the rear camera. The wipers will
clear the rear camera and either stop or return to your preset speed. For more
washer cycles, turn and hold the band. See
Rear Camera Mirror
029.
Compass
The vehicle may have a compass display on
the Driver Information Center (DIC). The
compass receives its heading and other
information from the Global Positioning
System (GPS) antenna, Electronic Stability
Control (ESC), and vehicle speed information.
The compass system is designed to operate
for a certain number of miles or degrees of
turn before needing a signal from the GPS
satellites. When the compass display shows
CAL, drive the vehicle for a short distance in
an open area where it can receive a GPS
signal. The compass system will
automatically determine when a GPS signal
is restored and provide a heading again.
Clock
Set the time and date using the
infotainment system. See "Time/Date" under
Settings (Base Radio) 0177 or
Settings (Uplevel Radio) 0178.

The engine oil pressure gauge shows the
engine oil pressure in kPa (kilopascals)
or psi (pounds per square inch) when the
engine is running.
Oil pressure can vary with engine speed,
outside temperature, coolant temperature,
and oil viscosity.
On some models, the oil pump will vary
engine oil pressure according to engine
needs. Oil pressure may change quickly as
the engine speed or load varies. This is
normal. If the oil pressure warning light or
Driver Information Center (DIC) message
indicates oil pressure outside the normal
operating range, check the engine oil as
soon as possible.
SeeEngine Oil 0325.
Caution
Lack of proper engine oil maintenance
can damage the engine. Driving with the
engine oil low can also damage the
engine. The repairs would not be covered
by the vehicle warranty. Check the oil
level as soon as possible. Add oil if
required, but if the oil level is within the
operating range and the oil pressure is
(Continued)
Caution (Continued)
still low, have the vehicle serviced.
Always follow the maintenance schedule
for changing engine oil.
If the vehicle has a diesel engine, see the
Duramax diesel supplement.
Uplevel
This gauge displays while the lower gauges
are configured to display four gauges. To
change gauge configurations, see “Options”

This light comes on when the air suspension
is in Service Mode or Alignment Mode.
SeeFour Corner Air Suspension System
0 231.
Tire Pressure Light
If equipped with the Tire Pressure Monitor
System (TPMS), this light comes on briefly
when the vehicle is started. It provides
information about tire pressures and
the TPMS.
When the Light Is On Steady
This indicates that one or more of the tires
are significantly underinflated.
A Driver Information Center (DIC) tire
pressure message may also display. Stop as
soon as possible, and inflate the tires to the
pressure value shown on the Tire and
Loading Information label. See Tire Pressure
0 358. When the Light Flashes First and Then Is On
Steady
If the light flashes for about a minute and
then stays on, there may be a problem with
the TPMS. If the problem is not corrected,
the light will come on every time the
vehicle is started. See
Tire Pressure Monitor
Operation 0361.
Engine Oil Pressure Light
Caution
Driving the vehicle with low engine oil
pressure can damage the engine and the
repairs would not be covered by the
vehicle warranty.
If the engine oil pressure light comes on
while driving:
1. Stop in a safe location and turn off the engine.
2. Check the oil level. See Engine Oil
0 325.
3. Add oil if the oil level is below the normal operating range.
(Continued)
Caution (Continued)
4. Restart the vehicle. If the engine oilpressure light stays on for more
than 10 seconds, turn the vehicle
back off. Do not restart the vehicle.
See your dealer for service.
This light should come on briefly when the
engine starts. When the engine is off and
the vehicle is on, the light should remain
illuminated. If it does not come on under
either condition, contact your dealer.
If the light comes on and stays on when the
engine is running, it may not have adequate
oil pressure. The oil level may be low or
there may be some other oil system
problem. Turn the engine off when it is safe
to do so and contact your dealer.

292 Driving and Operating
Caution
If the vehicle tires begin to spin and the
vehicle begins to slide toward the water,
remove your foot from the accelerator
pedal and apply the brake pedal. Seek
help to have the vehicle towed up
the ramp.
Maintenance when Trailer Towing
The vehicle needs service more often when
used to tow trailers. SeeMaintenance
Schedule 0400. It is especially important to
check the engine oil, axle lubricant, belts,
cooling system, and brake system before
and during each trip.
Check periodically that all nuts and bolts on
the trailer hitch are tight.
Engine Cooling when Trailer Towing
The cooling system may temporarily
overheat during severe operating conditions.
See Engine Overheating 0332.
Trailer Towing
If equipped with a diesel engine, see the
Duramax diesel supplement.
Caution
Towing a trailer improperly can damage
the vehicle and result in costly repairs
not covered by the vehicle warranty. To
tow a trailer correctly, follow the
directions in this section and see your
dealer for important information about
towing a trailer with the vehicle.
Trailering is different than just driving the
vehicle by itself. Trailering means changes in
handling, acceleration, braking, durability,
and fuel economy. Successful, safe trailering
takes correct equipment, and it has to be
used properly.
The following information has many
time-tested, important trailering tips and
safety rules. Many of these are important
for your safety and that of your passengers.
Read this section carefully before pulling a
trailer.
Trailer Weight
{Warning
Never exceed the towing capacity for
your vehicle.
Safe trailering requires monitoring the
weight, speed, altitude, road grades, outside
temperature, dimensions of the front of the
trailer, and how frequently the vehicle is
used to tow a trailer.
Trailering Weight Ratings
When towing a trailer, the combined weight
of the vehicle, vehicle contents, trailer, and
trailer contents must be below all of the
maximum weight ratings for the vehicle,
including:
.Gross Combined Weight Rating (GCWR)
.Gross Vehicle Weight Rating (GVWR)
.Maximum Trailer Weight Rating
.Gross Axle Weight Rating-Rear (GAWR-RR)
.Maximum Trailer Tongue Weight Rating
See “Weight-Distributing Hitch Adjustment”
under Towing Equipment 0296 to
determine if equalizer bars are required to
obtain the maximum trailer weight rating.
