Jeep 2009 Compass - Owner Manual - Manual (Page 264)

Where one or more wheels have wheel spin or if addi-
tional traction is needed in sand, deep snow, or loose
traction surfaces, activate the 4WD LOCK switch by
pulling up once and releasing. This locks the center
coupling allowing more torque to be sent to the rear
wheels. The 4WD Indicator Light will come on in the
cluster. This can be done on the fly, at any vehicle speed.
To deactivate, simply pull on the switch one more time.
The 4WD Indicator Light will then go out.
NOTE: Refer to Electronic Stability Program (ESP) in the
“Electronic Brake Control System” section of this manual
for additional information.
DRIVING ON SLIPPERY SURFACES
Acceleration
Rapid acceleration on snow covered, wet, or other slip-
pery surfaces may cause the front wheels to pull errati-
cally to the right or left. This phenomenon occurs when
there is a difference in the surface traction under the front
(driving) wheels.
WARNING!
Rapid acceleration on slippery surfaces is dangerous.
Unequal traction can cause sudden pulling of the
front wheels. You could lose control of the vehicle
and possibly have an accident. Accelerate slowly and
carefully whenever there is likely to be poor traction
(ice, snow, wet, mud, loose sand, etc.).
