Driving Winter operating tips for Arctic operation -20°F (-29°C) and below The following information is provided as a guideline only, and is not intended to be the only source of possible solutions in resolving extreme cold temperature issues. Starting aids: The use of the factory engine block heater (if equipped) (refer to Engine block heater in the Driving chapter of the Owner's Guide) will assist in engine starting in extreme cold ambient temperatures. WARNING: Do not use starting fluid, such as ether, in the air intake system (see air filter decal). Such fluid could cause immediate explosive damage to the engine and possible personal injury. Idle control: • Your vehicle may have a factory option for a stationary elevated idle control (SEIC) through dash-mounted upfitter switches will allow the operator to elevate the idle rpm for extended idle periods, as well as aftermarket equipment such as PTO operation. This feature must be configured even if ordered from the factory. See your authorized dealer for required upfitting. Operation in snow and rain Vehicle operation in heavy snowfall or extreme rain conditions may feed excessive amounts of snow/water into the air intake system. This could plug/soak the air filter with snow and may cause the engine to lose power and possibly shut down. The following actions are recommended after operating the vehicle up to 200 miles (320 km) in snowfall or extreme rain: • Snow: At the earliest opportunity, open the hood and clear all the snow and ice from the air filter housing inlet (do not remove the foam filter) and reset the air filter restriction gauge. Note: Removal of the foam filter degrades vehicle performance during snow and hot weather conditions. • Extreme rain: The air filter will dry after about 15-30 minutes at highway speeds. At the earliest opportunity, open the hood and reset the air filter restriction gauge. Refer to Air filter and restriction gauge in the Maintenance and Specifications chapter of this supplement for more information. 13 2012 Diesel (67l) Supplement, 3rd Printing USA (fus)
