Jaguar Assist (North America only)
Assist is an integrated vehicle emergency message
system (VEMS) that uses the Jaguar security
response center for emergency roadside
assistance via the Jaguar in-car telephone
installation. The global positioning system (GPS) is
used to identify the position, direction of travel
and speed of the vehicle. Access to the Assist
feature is through the use of the Navigation
system. The emergency assistance feature allows
rapid access to the emergency services (police,
fire or ambulance) and roadside assistance. Once
assistance has been requested and the vehicle
location confirmed, the appropriate services are
contacted for assistance to be dispatched. In the
unfortunate event of an airbag deployment, the
system will automatically place an emergency call.
Access to the system is gained by pressing the
information button on the Navigation front panel
screen (the ignition must be in position ÔIÕ or ÔIIÕ).
While in use, a sequence of messages is displayed
on the LCD.
Note: If an Assist call is initiated and the operator
cannot establish voice communication, police
assistance will be dispatched to the vehicle.
The system can be used wherever a cellular
phone service is available. The Jaguar phone must
be connected to the vehicle, working correctly
and registered with a cellular network. A roaming
airtime agreement is required so that the system
can be used in all areas.
Diagnostic Light
A diagnostic light is integrated into the
information (ASSIST) button. The diagnostic light
flashes throughout an activation but stays on
continuously when a failure is detected. A
message is given on the display: ÔASSIST
FAILUREÕ. There are four potential failure modes:
1. No VEMS menu is displayed when the
information ASSIST button is pressed
2. No activation is performed when the enter
button is pressed to make a selection3. VEMS is unable to compute the location of
the vehicleÕs current position
4. The Navigation system is unable to display
any VEMS messages or would display the
wrong VEMS messages.
Real Time Traffic Information (RTTI)
In the UK the provider for RTTI is ÔTrafficmasterÕ.
Information is collected from their own unique
network of infra-red road sensors which monitor
the average speed of traffic. This information is
sent by radio data link to TrafficmasterÕs
operational headquarters. After processing and
editing the information, it is transmitted in real
time, in words and graphics to Trafficmaster
control modules installed in vehicles. RTTI will not
be available on early vehicles but could be Dealer
fitted retrospectively.
Other markets will use different traffic congestion
information services which will depend on market
infrastructure and service provider support. Japan
will use the ÔVehicle Information and
Communications SystemÕ (VICS).
