CAUTION!
When using ERS for engine braking while descend-
ing steep grades, be careful not to overspeed the
engine. Apply the brakes as needed to prevent en-
gine overspeed.
Overdrive Operation
The automatic transmission includes an electronically
controlled Overdrive (fifth and sixth gears). The trans-
mission will automatically shift into Overdrive if the
following conditions are present:
•The shift lever is in the DRIVE position.
• The transmission fluid has reached an adequate tem-
perature.
• The engine coolant has reached an adequate tempera-
ture. •
The vehicle speed is sufficiently high.
• The driver is not heavily pressing the accelerator.
When To Use TOW/HAUL Mode
When driving in hilly areas, towing a trailer, carrying a
heavy load, etc., and frequent transmission shifting oc-
curs, press the TOW/HAUL switch to activate TOW/
HAUL mode. This will improve performance and reduce
the potential for transmission overheating or failure due
to excessive shifting. When operating in TOW/HAUL
mode, transmission upshifts are delayed, and the trans-
mission will automatically downshift (for engine brak-
ing) when the throttle is closed and/or during steady
braking maneuvers.
296 STARTING AND OPERATING

Filling The Def Tank In Cold Climates
Since DEF will begin to freeze at 12°F (-11°C), your
vehicle is equipped with an automatic DEF heating
system. This allows the DEF injection system to operate
properly at temperatures below 12°F (-11°C). If your
vehicle is not in operation for an extended period of time
with temperatures below 12°F (-11°C), the DEF in the
tank may freeze. If the tank is overfilled and freezes, it
could be damaged. Therefore, do not overfill the DEF
tank.
The DEF tank on these vehicles is designed with a large
amount of full reserve. So the level sensor will indicate a
Full reading even before the tank is completely full. To
put it another way, there’s additional storage capacity in
the tank above the Full mark that’s not represented in the
gauge. You may not see any movement in the reading –
even after driving up to 2,000 miles in some cases.The difference this makes varies by vehicle. Heavy-duty
pickup trucks have a 5.7-gallon tank that will display a
Full reading when about 90 percent full. This means that
drivers can consume at least 10 percent of a truly full DEF
tank without seeing any visible change in the gauge
reading. Chassis cabs have a larger 9-gallon tank, and
will display a Full reading when about 75 percent full. So
drivers can consume 25 percent of a truly full DEF tank
without seeing any visible change in the gauge reading.
Extra care should be taken when filling with portable
containers to avoid overfilling. Note the level of the DEF
gauge in your instrument cluster. On pickup applica-
tions, you may safely add a maximum of 2 gallons of DEF
from portable containers when your DEF gauge is read-
ing ½ full. On Chassis Cab applications a maximum of 2
gallons may be added when the DEF gauge is reading ¾
full.
