begin driving directions. Routes that are sent to the navigation screen can only be canceled through the navigation system.

See www.onstar.com (U.S.) or www.onstar.ca (Canada).

Connections

The following services help with staying connected.

For coverage maps, see www.onstar.com (U.S.) or www.onstar.ca (Canada).

Ensuring Security

    Change the default passwords for the Wi-Fi hotspot and myGMC mobile application. Make these passwords different from each other and use a combination of letters and numbers to increase the security.
    Change the default name of the SSID (Service Set Identifier). This is your network’s name that is visible to other wireless devices. Choose a unique name

and avoid family names or vehicle descriptions.

Wi-Fi Hotspot (If Equipped)

The vehicle may have a built-in Wi-Fi hotspot that provides access to the Internet and web content at 4G LTE speed. Up to seven mobile devices can be connected.

A data plan is required. Use the in-vehicle controls only when it is safe to do so.

    To retrieve Wi-Fi hotspot information, press = to open the OnStar app on the infotainment display, then select Wi-Fi Hotspot. On some vehicles, touch Wi-Fi or Wi-Fi Settings on the screen.
    The Wi-Fi settings will display the Wi-Fi hotspot name (SSID), password, and on some vehicles, the connection type (no Internet connection, 3G, 4G, 4G LTE), and signal quality (poor, good, excellent). The LTE icon shows connection to Wi-Fi. It is possible that the icon may not illuminate even though the vehicle has an active connection.
    To change the SSID or password, press Q or call 1-888-4ONSTAR to connect with an Advisor. On some vehicles, the SSID and password can be changed in the Wi-Fi Hotspot menu.

After initial set-up, your vehicle’s Wi-Fi hotspot will connect automatically to your mobile devices. Manage data usage by

turning Wi-Fi on or off on your mobile device, using the myGMC mobile app, or by contacting an OnStar Advisor. On some vehicles, Wi-Fi can also be managed from the Wi-Fi Hotspot menu.

MyGMC Mobile App (If Available)

Download the myGMC mobile app to compatible Apple and Android smartphones. GMC users can access the following services from a smartphone:

    Remotely start/stop the vehicle, if factory-equipped.
    Lock/unlock doors, if equipped with automatic locks.
    Activate the horn and lamps.
    Check the vehicle’s fuel level, oil life,

or tire pressure, if factory-equipped with

the Tire Pressure Monitor System.

    Send destinations to the vehicle.
    Locate the vehicle on a map (U.S. market only).
    Turn the vehicle's Wi-Fi hotspot on/off, manage settings, and monitor data consumption, if equipped.
    Locate a dealer and schedule service.
    Request roadside assistance.
    Set a parking reminder with pin drop, take a photo, make a note, and set a timer.
    Connect with GMC on social media.

Features are subject to change. For myGMC mobile app information and compatibility, see my.gmc.com.

An active OnStar or connected service plan may be required. A compatible device, factory-installed remote start, and power locks are required. Data rates apply. See www.onstar.com for details and system limitations.

Contact an OnStar Advisor to unlock the doors or sound the horn and flash the lamps.

OnStar Advisors can provide offers from restaurants and retailers on your route, help locate hotels, or book a room. These services vary by market.

By monitoring and reporting on the vehicle's key systems, OnStar Advanced Diagnostics, if equipped, provides a way to keep up on maintenance. Capabilities vary by model.

See www.onstar.com for details and system limitations. Features are subject to change. For updates on feature capabilities, see my.gmc.com. Message and data rates may apply.
