Starting Operation in snow Vehicle operation in heavy snowfall or in dry loose snow that may swirl around the front of the vehicle may feed excessive amounts of snow into the air intake system. This could plug the air cleaner with snow and cause the engine to stall. Refer to Air filter restriction gauge in the Diesel information chapter and Engine air filter in the Warning lights chapter for more information. Operation in standing water Ingestion of water into the Diesel engine can result in immediate and severe damage to the engine. If driving through water, slow down to avoid splashing water into the intake. If the engine stalls, and ingestion of water into the engine is suspected, do not try to restart the engine. Consult your dealer for service immediately. Follow the cylinder compression test procedure outlined in the Workshop Manual, then check the engine oil for contamination.
