Autostop, the Climate Controls system may automati-
cally adjust airflow to maintain cabin comfort. Customer
settings will be maintained upon return to an engine
running condition.
Possible Reasons The Engine Does Not AUTO
STOP
Prior to engine shut down, the system will check many
safety and comfort conditions to see if they are fulfilled.
In following situations the engine will not stop:
•Driver ’s seat belt is not buckled
• Driver ’s door is not closed
• Outside temperature is less than 1°F (–17°C) or greater
than 104°F (40°C)
• Battery temperature too warm or cold
• The vehicle is on a steep grade •
Cabin heating or cooling is in process and an accept-
able cabin temperature has not been achieved
• HVAC is set to full defrost mode at a high blower
speed
• Engine has not reached normal operating temperature
• Battery discharged
• The transmission is not in DRIVE
• Hood is open
• Vehicle is in 4LO transfer case mode
Other factors which can inhibit AutoStop include: fuel
level, accelerator pedal input, engine temp too high and
steering angle.
It may be possible for the vehicle to be driven several
times without the STOP/START system going into a
STOP/START READY state under more extreme condi-
tions of the items listed above.

Towing Tips
Before setting out on a trip, practice turning, stopping
and backing the trailer up in an area away from heavy
traffic.
Automatic Transmission
The “DRIVE” range can be selected when towing. The
transmission controls include a drive strategy to avoid
frequent shifting when towing. However, if frequent
shifting does occur while in DRIVE, select “TOW/
HAUL” mode or select a lower gear range (using the
Electronic Range Select (ERS) switches).
NOTE:Using “TOW/HAUL” mode or selecting a lower
gear range (using the ERS switches) while operating the
vehicle under heavy loading conditions will improve
performance and extend transmission life by reducing
excessive shifting and heat build up. This action will also
provide better engine braking. When towing a loaded trailer up steep grades at low
speeds (20 mph [32 km/h] or below), holding your
vehicle in first gear (using the ERS switches) can help to
avoid transmission overheating.
If you regularly tow a trailer for more than 45 minutes of
continuous operation, then change the automatic trans-
mission fluid and filter(s) as specified for
police, taxi,
fleet, or frequent trailer towing. Refer to “Maintenance
Schedule” for the proper maintenance intervals.
NOTE: Check the automatic transmission fluid level
before towing (6-speed automatic only).
Tow/Haul Mode
To reduce potential for automatic transmission overheat-
ing, turn the “TOW/HAUL” feature ON when driving in
hilly areas, or select a lower gear range (using the
Electronic Range Select (ERS) switches) on more severe
grades.
