Service Electric Parking Brake; Light; Antilock Brake System (Abs); Warning Light - Cadillac ATS 2017 Owner's Manual

124 INSTRUMENTS AND CONTROLS
Service Electric Parking
Brake Light
This light should come on briefly
when starting the vehicle. If it does
not come on, have it fixed so it will be
ready to warn if there is a problem.
If this light stays on, there is a
problem with the Electric Parking
Brake system or another system on
the vehicle that is causing the parking
brake system to work at a reduced
level. The vehicle can still be driven,
but should be taken to a dealer as
soon as possible. See the information
for the Electric Parking Brake under
Parking Brake (Electric) 0 238 or
Parking Brake (Manual) 0 240. If a
message displays in the Driver
Information Center (DIC), see Brake
System Messages 0 136.
Antilock Brake System
(ABS) Warning Light
This light comes on briefly when the
engine is started.
If the light does not come on, have it
fixed so it will be ready to warn if
there is a problem.
If the light comes on while driving,
stop as soon as it is safely possible
and turn off the vehicle. Then start
the engine again to reset the system.
If the ABS light stays on, or comes on
again while driving, the vehicle needs
service. A chime may also sound when
the light comes on steady.
If the ABS light is the only light on,
the vehicle has regular brakes, but the
antilock brakes are not functioning.
If both the ABS and the brake system
warning light are on, the vehicle's
antilock brakes are not functioning
and there is a problem with the
regular brakes. See your dealer for
service.

Lane Keep Assist (LKA)

Light

If available, this light comes on briefly
while starting the vehicle.
If it does not come on, have the
vehicle serviced.
This light is green if LKA is available
to assist.
LKA may assist by gently turning the
steering wheel if the vehicle
approaches a detected lane marking
without using the turn signal in that
direction. The LKA light will turn
amber.
