L/M(Driver and Passenger
Heated Seats): For vehicles with
heated seats, see Heated Front
Seats on page 3‑8.
Remote Start Climate Control
Operation: For vehicles with the
remote vehicle start feature, the
climate control system may run
when the vehicle is started remotely. The system uses the driver's
previous settings to heat or cool
the inside of the vehicle. The front
heated seats will turn on if it is cold
outside. The heated seat indicator
lights do not come on during a
remote start. See
Remote Vehicle
Start on page 2‑5.Sensors
The solar sensor, located on top
of the instrument panel near the
windshield, monitors the solar heat.
The climate control system
uses the information to adjust
the temperature, fan speed,
recirculation, and air delivery mode.
Do not cover the solar sensor or the
system will not work properly.
Air Vents
Use the air outlets, located in the
center and on the side of the
instrument panel, to direct the
airflow. Use the thumbwheels
located near the center air outlets,
to open or close off the airflow.
Operation Tips
.Clear away any ice, snow,
or leaves from air inlets at the
base of the windshield that could
block the flow of air into the
vehicle.
.Keep the path under the front
seats clear of objects to help
circulate the air inside of the
vehicle more effectively.
.Use of non‐GM approved hood
deflectors can adversely affect
the performance of the system.
Check with your dealer before
adding equipment to the outside
of the vehicle.

Object Detection
Systems
Ultrasonic Parking Assist
For vehicles with the Ultrasonic
Rear Parking Assist (URPA) system,
it assists the driver with parking
and avoiding objects while in
R (Reverse). URPA operates at
speeds less than 8 km/h (5 mph),
and the sensors on the rear bumper
detect objects up to 2.5 m (8 ft)
behind the vehicle, and at least
20 cm (8 in) off the ground.
{WARNING
The Ultrasonic Rear Parking
Assist (URPA) system does not
replace driver vision. It cannot
detect:
.Objects that are below the
bumper, underneath the
vehicle, or too close or far
from the vehicle.
.Children, pedestrians,
bicyclists, or pets.
If you do not use proper care
before and while backing, vehicle
damage, injury, or death could
occur. Even with URPA, always
check behind the vehicle before
backing up. While backing, be
sure to look for objects and check
the vehicle's mirrors.
How the System Works
URPA comes on automatically
when the shift lever is moved into
R (Reverse). A single tone sounds
to indicate the system is working.
URPA operates only at speeds less
than 8 km/h (5 mph).
An obstacle is indicated by audible
beeps. The interval between the
beeps becomes shorter as the
vehicle gets closer to the obstacle.
When the distance is less than
30 cm (12 in) the beeping is
continuous for 5 seconds.
To be detected, objects must be at
least 20 cm (8 in) off the ground and
below taillamp level. Objects must
also be within 2.5 m (8 ft) from the
rear bumper. The distance objects
can be detected may be less during
warmer or humid weather.

PARK ASSIST OFF displays on the
Driver Information Center (DIC) to
indicate that URPA is off. The
message disappears after a short
period of time.
SeeObject Detection System
Messages on page 5‑27 for URPA
messages.
Turning the System On and Off
The URPA system can be turned
on and off using the infotainment
system controls. See Vehicle
Personalization on page 5‑30 for
more information.
URPA defaults to the on setting
each time the vehicle is started.
When the System Does Not
Seem to Work Properly
If the URPA system does not
activate due to a temporary
condition, the message PARK
ASSIST OFF displays on the DIC.
See Driver Information Center (DIC)
on page 5‑20 for more information.
This can occur under the following
conditions:
.The driver has disabled the
system.
.The ultrasonic sensors are not
clean. Keep the vehicle's rear
bumper free of mud, dirt, snow,
ice, and slush. For cleaning
instructions, see Exterior Care
on page 10‑82.
.The park assist sensors are
covered by frost or ice, which
can occur after washing the
vehicle in cold weather. Keep
the sensors free of frost or ice.
.A trailer was attached to the
vehicle, or an object was
hanging out of the trunk during
the last drive cycle. Once the
object is removed, URPA will
return to normal operation.
.The vehicle's bumper is
damaged. Take the vehicle to
your dealer to repair the system.
.Other conditions may affect
system performance, such as
vibrations from a jackhammer or
the compression of air brakes on
a very large truck.

For additional information
regarding how much weight
the vehicle can carry, and an
example of the Tire and Loading
Information label, seeVehicle
Load Limits on page 9‑21. How
the vehicle is loaded affects
vehicle handling and ride
comfort. Never load the vehicle
with more weight than it was
designed to carry.
When to Check
Check the tires once a month or
more. Do not forget the compact
spare tire, if the vehicle has one.
The compact spare should be at
420 kPa (60 psi). For additional
information regarding the
compact spare tire, see
Compact Spare Tire on
page 10‑74. How to Check
Use a good quality pocket-type
gauge to check tire pressure.
Proper tire inflation cannot be
determined by looking at the tire.
Check the tire inflation pressure
when the tires are cold, meaning
the vehicle has not been driven
for at least three hours or no
more than 1.6 km (1 mi).
Remove the valve cap from the
tire valve stem. Press the tire
gauge firmly onto the valve to
get a pressure measurement.
If the cold tire inflation pressure
matches the recommended
pressure on the Tire and
Loading Information label, no
further adjustment is necessary.
If the inflation pressure is low,
add air until the recommended
pressure is reached. If the
inflation pressure is high, press
on the metal stem in the center
of the tire valve to release air.Re‐check the tire pressure with
the tire gauge.
Return the valve caps on the
valve stems to prevent leaks
and keep out dirt and moisture.
Tire Pressure Monitor
System
The Tire Pressure Monitor System
(TPMS) uses radio and sensor
technology to check tire pressure
levels. The TPMS sensors monitor
the air pressure in your tires and
transmit tire pressure readings to a
receiver located in the vehicle.
Each tire, including the spare
(if provided), should be checked
monthly when cold and inflated to
the inflation pressure recommended
by the vehicle manufacturer on
the vehicle placard or tire inflation
pressure label. (If your vehicle has
tires of a different size than the size
indicated on the vehicle placard or
