Limitations and disclaimers
GPS and GSM availability
Since Volvo On Call and your smart phone relies on GPS and GSM technology which are
based on the idea of a “clear line of sight from the sky”. Sould it not be the case some
features may lose part or whole functionality. This might be the case e.g. if you’re in a
parking garage under ground with bad or no GPS/GSM reception at all.
Data exchange
The Volvo On Call mobile application can’t retrieve data from the vehicle while in operation.
Your car will send data batches to the central Volvo On Call server every time you turn the
engine off and remove the key (in case of a keyless entry vehicle you need to move away
from the vehicle until the key doesn’t have contact with the vehicle anymore). Refreshed
information will be available within a minute.
Response time
Due to current technical limitations, the response times experienced with the Volvo On Call
application are typically:
· any command sent to the vehicle takes a minimum of five seconds to deliver.
· any response from the vehicle takes a minimum of five seconds to deliver.
This means that if you issue a command on your smart phone that requires the vehicle to
perform a task and in turn return an answer which shall be presented to your smart phone
screen, the complete trip from you to your car and back to you will have a total delay of
ideally 10 seconds, normally this time will be around 20 seconds.
(Note! In case the car has bad GSM reception and can't use GPRS data traffic, then the
complete trip from you to your car and back to you may have a total delay of one to two
minutes).
System sleep mode
In order to save the battery charge when the car is not used for longer periods the Volvo On
Call system has been set up to operate in the following way:
- First 72 hours (3 days) after engine shut off: the system is continuously available and
executes new requests immediatly
- 3 to 14 days after engine shut off: the system wakes up every hour to check for new
request and execute them
- After 14 days: the system turns to sleep mode and is no mobile app functionality requiring
communication with the vehicle is available.
