Ram Trucks 2010 3500 - User Guide - Manual (Page 27)

CAUTION!
Use of aftermarket exhaust brakes is not recommended and could lead to engine
damage.
WARNING!
Do not use the exhaust brake feature when driving in icy or slippery conditions as the
increased engine braking can cause the rear wheels to slide and the vehicle to swing
around with the possible loss of vehicle control, which may cause an accident
possibly resulting in personal injury or death.
NOTE: For optimum braking power, it is recommended to use the exhaust brake while in
TOW/HAUL mode.
IDLE-UP FEATURE (DIESEL/AUTOMATIC TRANSMISSION ONLY)
• The Idle-Up Feature uses the speed control switches to increase engine idle speed and
quickly warm the vehicle’s interior. This feature must be enabled by your dealer. See
your local Dodge dealer.
• With the transmission in PARK, the parking brake applied, and the engine running,
push the speed control ON/OFF switch on, then push the SET switch.
• The engine RPM will go up to 1100 RPM. To increase the RPM, push and hold the
ACCEL/RESUME switch and the idle speed will increase to approximately 1500 RPM. To
decrease the RPM, push and hold the DECEL switch and the idle speed will decrease
to approximately 1100 RPM.
• To cancel the Idle Up Feature, either push the CANCEL switch, push the ON/OFF switch

Instrument Panel below the climate controls.
• The “Light Load Inflation” and “Max Load Inflation” tire pressures recommended for
your vehicle based on vehicle loading are found on the Supplemental Tire Pressure
Information Label located on the rear face of the driver front door.
• When the vehicle is in the “Light Load Inflation” setting, the Tire Light Load Inflation
switch is On. The indicator light is Off when in the “Max Load Inflation” setting.
Light Load Inflation (Indicator Light On)

the Supplemental Tire Pressure Information Label, inflate or deflate tires to the correct
“Light Load Inflation” pressure. If the indicator light is not on,
the mode can be
changed by pushing the switch once.
