The brake lights come on automatically when
the brakes are applied.
The ABS system helps to improve vehicle
control (stopping and steering) during severe
braking conditions by limiting brake lockup.

Symbol Specification
Adaptive brake lights
When the system "senses" impending lockup,
braking pressure is automatically modulated
in order to help prevent lockup that could
lead to a skid.
The adaptive brake lights activate in the event
of sudden braking or if the ABS system is
activated. This function causes an additional
taillight on each side of the vehicle to illumi-
nate to help alert vehicles traveling behind.
Steady glow – Check the brake
fluid level. If the level is low, fill
with brake fluid and check for
the cause of the brake fluid
loss.
The system performs a brief self-diagnostic
test when the engine has been started and
driver releases the brake pedal. Another auto-
matic test may be performed when the vehi-
cle first reaches a speed of approximately
6 mph (10 km/h). The brake pedal will pulsate
several times and a sound may be audible
from the ABS control module, which is nor-
mal.
The adaptive brake lights activate if:
Automatic function check:
steady glow for two seconds
when the engine is started.
The ABS system activates for more than
approximately a half second

In the event of sudden braking while the
vehicle is moving at speeds above
approximately 6 mph (10 km/h).

WARNING
When the vehicle has come to a stop, the
brake lights and additional taillights remain on
for as long as the brake pedal is depressed or
until braking force on the vehicle is reduced.
If
and
come on at the
same time and the brake level is below the
MIN mark in the reservoir or if a brake sys-
tem-related message is shown in the infor-
mation display: DO NOT DRIVE. Have the
vehicle towed to a trained and qualified
Volvo service technician and have the
brake system inspected.
