During extremely cold temperatures (-22°F [-30°C] or

below), transmission operation may be modified depend-

ing on engine and transmission temperature as well as

vehicle speed. Normal operation will resume once the

transmission temperature has risen to a suitable level.
SPORT (S)

The SPORT shift mode alters the transmission’s auto-

matic shift schedule for sportier driving. Upshift speeds

are increased to make full use of available engine power.

To switch between DRIVE and SPORT shift mode, tap the

shift lever rearward. SPORT shift mode is only accessible

from DRIVE.
Transmission Limp Home Mode
Transmission function is monitored electronically for

abnormal conditions. If a condition is detected that could

result in transmission damage, Transmission Limp Home

Mode is activated. In this mode, the transmission may

operate only in certain gears, or may not shift at all.

Vehicle performance may be severely degraded 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

illuminated. 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 message

indicates the transmission may not re-engage after en-

gine shutdown, perform this procedure only in a desired

location (preferably, at your authorized dealer).
1. Stop the vehicle.
