Maintenance
Note: To calibrate the steering angle
sensor, drive the vehicle above 30 mph
(50 km/h) for a minimum of 1.2 mi (2 km).
Make sure to drive straight ahead for a
minimum of 30 seconds. Several vehicle
functions are disabled and a warning light
could appear until the sensor is calibrated.
Battery Management System
The battery management system monitors
battery conditions and takes actions to
extend battery life. If excessive battery
drain is detected, the system temporarily
disables some of the following features:
•
Heated rear window.
•
Heated seats.
•
Climate control.
•
Heated steering wheel.
•
Audio unit.
•
Navigation system.
A message may appear in the information
display to alert you that battery protection
actions are active.
After battery replacement, or in some
cases after charging the battery with an
external charger, the battery management
system requires eight hours of vehicle sleep
time to relearn the battery state of charge.
During this time your vehicle must remain
fully locked with the ignition off.
Note: If you add electrical accessories or
components to the vehicle, it may adversely
affect battery performance and durability.
This may also affect the performance of
other electrical systems in the vehicle.
