OPERATING YOUR VEHICLE 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 or push the brake pedal. TIRE PRESSURE MONITOR SYSTEM (TPMS) - 2500 MODELS ONLY Tire Light Load Inflation Switch Description • The Tire Pressure Monitoring System on your vehicle has two different tire pressure settings based on vehicle loading. The Tire Light Load Switch is located on the 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) • If the passenger and cargo are less than the Light Load Pressure Definition shown 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. 25
