Chrysler 2010 300 - Owner Manual - Manual (Page 331)

To maximize fuel economy, your AWD vehicle automati-
cally defaults to rear-wheel drive (RWD) when road and
environmental conditions are such that wheel slip is
unlikely to occur. When specific road and environmental
conditions require increased levels of road traction, the
vehicle automatically shifts into AWD mode. Automatic
AWD operation could be activated by outside tempera-
ture, wheel slip, or other predetermined conditions (there
may be a slight delay for AWD engagement after a wheel
slip condition occurs). AWD can also be manually se-
lected by moving the shift lever into the AutoStick
௡ mode
(+/-) or activating the windshield wipers for an extended
period of time. Drive mode, RWD or AWD, is displayed
momentarily in the Electronic Vehicle Information Center
(EVIC) in the gage area of the vehicle display when the
transmission is first shifted into gear, and if the drive
mode changes during vehicle operation.
NOTE: If the “t CASE” or “SERVICE AWD SYSTEM”
warning message appears after engine start up, or during
driving, it means that the AWD system is not functioning
properly and that service is required. Refer to “Electronic
Vehicle Information Center (EVIC)” in “Understanding
Your Instrument Panel” for further information.
CAUTION!
All wheels must have the same size and type tires.
Unequal tire sizes must not be used. Unequal tire
size may cause failure of the front differential and/or
the transfer case.
DRIVING ON SLIPPERY SURFACES
Acceleration
Rapid acceleration on snow covered, wet, or other slip-
pery surfaces may cause the rear wheels to pull errati-
cally to the right or left. This phenomenon occurs when
there is a difference in the surface traction under the rear
(driving) wheels.
