The Electronic Stability Control (ESC)
monitors information from various vehicle
sensors and then compares the driver's
commands with the actual behavior of the
vehicle. If an unstable condition occurs - a
sudden evasive movement for example -
ESC intervenes within fractions of a
second via the engine computer and
brake system and attempts to stabilize
the vehicle.

from increasing, and cause a false
diagnosis of a faulty speedometer.
• Turning the ESC off does not affect

equipped vehicle that is stuck in snow,
sand, or mud, use the ESC OFF but-
ton to temporarily deactivate the ESC
system.
