The electronic key in the steering lock must be in position
1 or 2 for the Tele Aid to be operational.Important!
The initial activation of the Tele Aid system may only be
performed by completing the subscriber agreement and
placing an acquaintance call using the “SOS” button.
Failure to complete either of these steps will result in a
system that is not activated.
If you have any questions regarding activation, please
call the Response Center at 1-800-756-9018 (in the USA)
or 1-888-923-8367 (in Canada).
(Te l ematic Alarm Identification on Demand)
The Tele Aid system consists of three types of response;
automatic and manual emergency, roadside assistance
and information.Emergency calls
An emergency call is initiated automatically
following an accident in which the Emergency
Tensioning Retractors (ETR’s) or airbags deploy,
An emergency call can also be initiated manually by
opening the cover next to the inside rear view mirror
labeled “SOS”, then pressing the button (for longer than
2 seconds) located under the cover. Once the emergency
call is in progress, the indicator
lamp in the “SOS”
button will begin to f lash. All information relevant to the
emergency, such as the location of the vehicle
(determined by the GPS satellite location system),
vehicle model, identification number and color are
generated.
A voice connection between the Response Center and
the occupants of the vehicle will be established
automatically soon after the emergency call has been
initiated. The Response Center will attempt
to determine more precisely the nature of the accident
provided they can speak to an occupant of the vehicle.

If the electronic key is left in the steering lock position 0
for an extended period of time, it can no longer be
turned in the lock. In this case, remove electronic key
from steering lock and reinsert.
Caution!
To prevent accelerated battery discharge and a possible
dead battery, always remove the electronic key from the
steering lock. Do not leave the electronic key in steering
lock position 0.Notes:
A warning sounds when the driver’s door is opened
while the electronic key is in steering lock position 1

With the engine at idle speed, the charging rate of the
alternator (output) is limited.
It is therefore recommended that you turn off
unnecessary electrical consumers while driving in stop-
and-go traffic. This precaution helps to avoid draining of
the battery.
Unnecessary strain on the battery and charging system
may be minimized by turning off the following power
consumers, for example: Heated seats, rear window
defroster. In addition, the automatic climate air volume
control should be set to the lowest position.
The steering lock can only be unlocked with the vehicle
battery properly charged and connected.
