2. Push the “Hill Descent” button. The “Hill Descent
Control Indicator Light” in the instrument cluster will
turn on solid.
NOTE:
• If the transfer case is not in 4WD LOW range, the “Hill
Descent Control Indicator Light” will flash for five
seconds and HDC will not be enabled.
• If the ESC senses that the brakes are overheating the
“Hill Descent Control Indicator Light” will flash for
five seconds and HDC will become deactivated until
the brakes have cooled.
Disabling HDC
Push the “Hill Descent” button or shift the transfer case out
of 4WD LOW range. The “Hill Descent Control Indicator”
light in the instrument cluster will turn off.
AUXILIARY DRIVING SYSTEMS
Tire Pressure Monitor System (TPMS)
The Tire Pressure Monitoring System (TPMS) will warn the
driver of a low tire pressure based on the vehicle recom-
mended cold placard pressure.
The tire pressure will vary with temperature by about 1 psi
(7.0 kPa) for every 12°F (6.5°C). This means that when the
outside temperature decreases, the tire pressure will de-
crease. Tire pressure should always be set based on cold
inflation tire pressure. This is defined as the tire pressure
after a vehicle has not been driven for more than three
hours, or driven less than 1 mile (1.6 km) after a three-hour
period. Refer to “Tires” in “Servicing and Maintenance” for
information on how to properly inflate the vehicle’s tires.
The tire pressure will also increase as the vehicle is driven;
this is normal and there should be no adjustment for this
increased pressure.
The TPMS will warn the driver of a low tire pressure if the
tire pressure falls below the low pressure warning thresh-
old for any reason, including low temperature effects, or
natural pressure loss through the tire.
The TPMS will continue to warn the driver of low tire
pressure as long as the condition exists, and will not turn
off until the tire pressure is at or above recommended cold
placard pressure. Once the “Tire Pressure Monitoring Tell-
tale Light” has been illuminated, the tire pressure must be
increased to the recommended cold placard pressure in
order for the “Tire Pressure Monitoring Telltale Light” to be
turned OFF.
