Getting to Know Your LaCrosse18
Ultrasonic Rear Parking Assist
(if equipped)
Ultrasonic Rear Parking Assist (URPA)
detects objects up to 5 feet (1.5 m)
behind the vehicle when the shift lever
is in the Reverse position and vehicle
speed is less than 3 mph (5 km/h).
Three color-coded lights inside the
vehicle, above the rear window, provide
distance and system information to the
driver.
See Section 2 of your Owner Manual.
Antilock Brake System
The Antilock Brake System (ABS) helps
prevent a braking skid. The ABS warn-
ing light illuminates briefly when the
engine is started. Momentary motor or
clicking noises and slight brake pedal
movement are normal as the system
checks itself when reaching speeds of
approximately 3 to 5 mph.
See Section 4 of your Owner Manual.
Traction Control System
The Traction Control System (TCS)
limits wheelspin. TCS activates when it
senses one or both front wheels spin-
ning or losing traction. Then the system
reduces engine power and may upshift
the transaxle to limit wheelspin. It is nor-
mal to hear or feel the system working.
TCS is always enabled unless you dis-
able it manually to rock the vehicle free
from sand, mud or snow.
To disable TCS, press the (Traction
Control) button on the instrument panel.
The TCS warning light will come on.
Press the button again to turn TCS on.
See Section 4 of your Owner Manual.
StabiliTrak® – Stability Control
System (if equipped)
StabiliTrak is a computer-controlled
system that detects and corrects differ-
ences between the path you have
chosen and the vehicle’s actual direction
by applying brake pressure individually
at the appropriate wheel. When the
system activates, STABILITY CONTROL
ACTIVE displays on the Driver
Information Center.
See Section 4 of your Owner Manual.
