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 page 133.
For Towing A Disabled Vehicle page 209.
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), select TOW/HAUL mode or
use the Electronic Range Select (ERS) shift control to
select a lower gear range
page 94. Under these
conditions, using a lower gear range will improve perfor-
mance and extend transmission life by reducing exces-
sive 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. During extremely cold
temperatures (-16°F [-27°C] or below), operation may
briefly be limited to THIRD gear only. 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 remains in THIRD gear regardless of which for-
ward gear is selected. PARK, REVERSE, and NEUTRAL
will continue to operate. The Malfunction Indicator Light
(MIL) may be illuminated. Transmission Limp Home
Mode allows the vehicle to be driven to an authorized
dealer for service without damaging the transmission.
In the event of a momentary problem, the transmission
can be reset to regain all forward gears by performing
the following steps:
1. Stop the vehicle.
2. Shift the transmission into PARK.
3. Turn the ignition OFF.
4. Wait approximately 10 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 transmis-
sion. If the transmission cannot be reset, authorized
dealer service is required.
Electronic Range Select (ERS) Operation
The ERS shift control allows the driver to select the max
gear limit. For example, if you set the transmission gear
limit to FOURTH gear, the transmission will not shift
above FOURTH gear, but will shift through the lower
gears normally.
You can switch between DRIVE and ERS mode at any
vehicle speed. When the gear selector is in the DRIVE
position, the transmission will operate automatically,
shifting between all available gears. Moving the gear
selector to the ERS position (beside DRIVE) will activate
ERS mode, display the current gear in the instrument
cluster, and set that gear as the max gear limit. Once in
ERS mode, moving the gear selector forward “-” or rear-
ward “+” will change the max gear limit.
NOTE:
The transmission will still continue to use the optimal
highest gear, for the current driving conditions, within
the selected gear range limit.
To exit ERS mode, simply return the gear selector to the
DRIVE position.
