314 STARTING AND OPERATING
heavy loading conditions, (i.e., in hilly terrain, traveling
into strong head winds or while towing heavy trailers).
Under these conditions, using the "3" range will improve
performance and extend transaxle life by reducing exces-
sive shifting and heat buildup.
CAUTION!
If the transaxle operating temperature exceeds ac-
ceptable limits, the vehicle computer will override
DRIVE and select "5" range (on six-speed transaxles)
or "3" range (on four-speed transaxles) by changing
shift points. This is done to prevent transaxle damage
due to overheating.
Electronic Range Select (ERS) Operation
The Electronic Range Select (ERS) shift control allows
you to move the shift lever to the left (-) or right (+) when
the shift lever is in the DRIVE position, this allows the
selection of the desired top gear. For example, if you shift
the transaxle into third gear, the transaxle will never shift
above third gear, but can shift down into second or first
gear automatically, when needed.
Switching from ERS to DRIVE can be done at any vehicle
speed. To shift from DRIVE mode to ERS mode, move the
shift lever to the left (-) once. The current gear will be
maintained as the top gear. To disable ERS, simply press
and hold the shift lever to the right (+) until "D" is
displayed in the instrument cluster odometer.
WARNING!
Do not downshift for additional engine braking on a
slippery surface. The drive wheels could lose their
grip and the vehicle could skid, causing an accident
or personal injury.
