STARTING AND OPERATING 181 Automatic Transmission Tow/Haul Mode must be connected to properly ensure operator safety and prevent overloading vehicle systems. The DRIVE range can be selected when towing. The transmission controls include a drive strategy to avoid frequent shifting when towing. However, if frequent shifting does occur while in DRIVE, select TOW/HAUL mode or select a lower gear range (using the Electronic Range Select (ERS) shift control). To reduce potential for automatic transmission overheating, activate TOW/HAUL mode when driving in hilly areas, or select a lower gear range (using the Electronic Range Select (ERS) shift control) on more severe grades.
Cruise Control — If Equipped Attaching a snowplow to this vehicle could adversely affect performance of the airbag system in a collision. Do not expect that the airbag will perform as described earlier in this manual. WARNING! NOTE: Using TOW/HAUL mode or selecting a lower gear range (using the ERS shift control) while operating the vehicle under heavy loading conditions will improve performance and extend transmission life by reducing excessive shifting and heat build-up. This action will also provide better engine braking. 6-Speed Automatic Transmission Only Do not use on hilly terrain or with heavy loads.
When using the Cruise Control, if you experience speed drops greater than 10mph (16km/h), disengage until you can get back to cruising speed. 4 The “Lamp Out” indicator could illuminate if exterior lamps are not properly installed. CAUTION! Use Cruise Control in flat terrain and with light loads to maximize fuel efficiency. SNOWPLOW — IF EQUIPPED When towing a loaded trailer up steep grades at low speeds (20mph [32km/h] or below), holding your vehicle in FIRST gear (using the ERS shift control) can help to avoid transmission overheating. B EFORE P LOWING Snowplow Prep Packages are available as a factory installed option.
These packages include components necessary to equip your vehicle with a snowplow. Check the hydraulic system for leaks and proper fluid level. Check the mounting bolts and nuts for proper tightness. If you regularly tow a trailer for more than 45minutes of continuous operation, then change the automatic transmission fluid and filter(s) as specified for "police, taxi, fleet, or frequent trailer towing." Ъ page324. NOTE: Before installation of a snowplow it is highly recom mended that the owner/installer obtain and follow the recommendations contained within the current Body Builder’s Guide. See an authorized dealer, installer or snowplow manufacturer for this infor mation.
There are unique electrical systems that Check the runners and cutting edge for exces sive wear. The cutting edge should be ј to Ѕ inches (6 cm to 1.2 cm) above ground in snow plowing position. NOTE: Check the automatic transmission fluid level before towing (6-speed automatic only). Check that snowplow lighting is connected and functioning properly.
