CAUTION!
Towing the vehicle, coasting, or driving for
any other reason with the transmission in
NEUTRAL can cause severe transmission
damage. Refer to "Recreational Towing" in
"Starting And Operating" and "Towing A Dis-
abled Vehicle" in "What To Do In Emergen-
cies" for further information.
DRIVE (D)
This range should be used for most city and
highway driving. It provides the smoothest up-
shifts and downshifts, and the best fuel
economy. The transmission automatically up-
shifts through all forward gears. The DRIVE
position provides optimum driving characteris-
tics under all normal operating conditions.
When frequent transmission shifting occurs
(such as when operating the vehicle under
heavy loading conditions, in hilly terrain, travel-
ing into strong head winds, or while towing
heavy trailers), use the Paddle Shift switches
(refer to "Paddle Shift Mode" in this section for
further information) to select a lower gear. Un-

der these conditions, using a lower gear will
improve performance and extend transmission
life by reducing excessive shifting and heat
buildup.
During extremely cold temperatures (-22°F
[-30°C] or below), transmission operation may
be modified depending on engine and transmis-
sion temperature as well as vehicle speed.
Normal operation will resume once the trans-
mission temperature has risen to a suitable
level.
SPORT (S)
This mode alters the transmission's automatic
shift schedule for sportier driving. Upshift
speeds are increased to make full use of avail-
able engine power. To switch between DRIVE
and SPORT modes, tap the shift lever rearward.
SPORT mode is only accessible from DRIVE.
NOTE:
When Sport Mode is enabled, vehicles with
the Quadra-Lift™ air suspension system will
operate in "Aero" Mode. Please refer to
Quadra-Lift™ in Starting and Operating
for further information.
Transmission Limp Home Mode
Transmission function is monitored electroni-
cally for abnormal conditions. If a condition is
detected that could result in transmission dam-
age, Transmission Limp Home Mode is acti-
vated. In this mode, the transmission may op-
erate only in certain gears, or may not shift at
all. Vehicle performance may be severely de-
graded and the engine may stall. In some
situations, the transmission may not re-engage
if the engine is turned off and restarted. The
Malfunction Indicator Light (MIL) may be illumi-
nated. A message in the instrument cluster will
inform the driver of the more serious conditions,
and indicate what actions may be necessary.
In the event of a momentary problem, the
transmission can be reset to regain all forward
gears by performing the following steps:
NOTE:
In cases where the instrument cluster mes-
sage indicates the transmission may not
re-engage after engine shutdown, perform
this procedure only in a desired location
(preferably, at your authorized dealer).
