WARNING!
Do not coast in NEUTRAL and never turn off the igni-
tion to coast down a hill. These are unsafe practices
that limit your response to changing traffic or road
conditions. You might lose control of the vehicle and
have a collision.
CAUTION!
Towing the vehicle, coasting, or driving for any other
reason with the transmission in NEUTRAL can cause
severe transmission damage.
For Recreational Towing see
page 176.
For Towing A Disabled Vehicle see
page 287.
DRIVE (D)
This range should be used for most city and highway
driving. It provides the smoothest upshifts and down-
shifts, and the best fuel economy. The transmission
automatically upshifts through all forward gears.
When frequent transmission shifting occurs (such as
when operating the vehicle under heavy loading condi-
tions, in hilly terrain, traveling into strong head winds, or
while towing a heavy trailer), use the Electronic Range
Select (ERS) shift control to select a lower gear
page 121. Under these conditions, using a lower
gear will improve performance and extend transmission
life by reducing excessive shifting and heat buildup.
During cold temperatures, transmission operation may
be modified depending on engine and transmission
temperature as well as vehicle speed. This feature
improves warm-up time of the engine and transmission
to achieve maximum efficiency. Engagement of the
torque converter clutch is inhibited until the transmis-
sion fluid is warm. Normal operation will resume once
the transmission temperature has risen to a suitable
level.
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 trans-
mission 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 instru-
ment 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 indi-
cates the transmission may not re-engage after engine
shutdown, perform this procedure only in a desired
location (preferably, at an authorized dealer).
1. Stop the vehicle.
2. Shift the transmission into PARK (P), if possible. If
not, shift the transmission to NEUTRAL (N).
3. Push and hold the ignition switch until the engine
turns off.
4. Wait approximately 30 seconds.
5. Restart the engine.
6. Shift into the desired gear range. If the problem is
no longer detected, the transmission will return to
normal operation.
NOTE:
Even if the transmission can be reset, we recommend
that you visit an authorized dealer at your earliest pos-
sible convenience. An authorized dealer has diagnostic
equipment to assess the condition of your
transmission.
If the transmission cannot be reset, authorized dealer
service is required.
Electronic Range Select (ERS) Operation
The ERS shift control allows the driver to limit the high-
est available gear when the transmission is in DRIVE
and ERS mode is not active. For example, if you set the
transmission gear limit to FOURTH gear, the transmis-
sion will not shift above FOURTH gear (except to prevent
engine overspeed), but will shift through the lower
gears normally.
You can switch between DRIVE and ERS mode at any
vehicle speed. When the transmission gear selector is
in DRIVE, the transmission will operate automatically,
shifting between all available gears. Tapping the “-”
button (on the steering wheel) will activate ERS mode,
display the current gear in the instrument cluster, and
set that gear as the top available gear. Once in ERS
mode, tapping the “-” or “+” button will change the top
available gear.
