AUTOMATIC “SMART” EXHAUST BRAKE
– (DIESEL ONLY)
• Automatic Exhaust Brake technology deliv- ers smoother, less aggressive exhaust brak-
ing characteristics during downhill de-
scents. Although it can apply full exhaust
braking force if needed, Automatic Exhaust
Brake may not apply obvious braking if the
vehicle speed is not increasing. Automatic
Exhaust Brake is intended to maintain ve-
hicle speed while Full Exhaust Brake is in-
tended to reduce vehicle speed.
• Automatic Exhaust Brake can be enabled by pushing the exhaust brake button again any
time after the normal Full Exhaust Brake has
been turned on. The “Exhaust Brake Indica-
tor” in the instrument cluster will change
from yellow to green when Automatic Ex-
haust Brake is enabled. Pushing the exhaust
brake button again will toggle the exhaust
brake mode to off.
Adding Diesel Exhaust Fluid (DEF)
The DEF gauge (located in the instrument clus-
ter) will display the level of DEF remaining in
the tank.
Completely fill the DEF tank through the diesel
exhaust fluid fill location at every maintenance
interval, or before if prompted by the instru-
ment cluster display.
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.
