When you are driving through water do notexceed 4 mph (7 km/h).
Never stop or shut a vehicle off whencrossing deep water unless your vehicleingested water into the engine air intake.If the engine stalls, do not attempt torestart it. Keep the doors fully closed duringa water crossing.
Extra care must be taken crossing any typeof water. Do not drive into water unlessnecessary. Only drive through areas thatare designated and approved. Determineexit points that are downstream of yourentry point to allow for drifting. If there areother vehicles ahead, wait until they haveleft the water. Unsettled water can makea safe passage more challenging.
High currents even in shallow water canwash the dirt out from around your tires orpush your vehicle across slippery rocks orsurfaces. Never attempt to cross flowingwater that is deeper than your vehicle'sground clearance. Even in low currents yourvehicle's body surface area can be pusheddownstream and out of control. Do notcross any body of water that is fast flowingand rising, wait for the flow rate to reduce.
Vehicles used to traverse water regularlyshould be periodically inspected for signsof water ingestion in all of the vehicle'sfluids. If water is found inside your vehiclefluids, service your vehicle or see anauthorized dealer.
After driving through water and as soon asit is safe to do so, check the brakes, horn,lights, and steering wheel to make sureeverything is still in working order.
AFTER DRIVING YOUR VEHICLEOFF-ROAD
WARNING: After off-road use,before returning to the road, check thewheels and tires for damage. Off-roaduse may cause damage to your wheelsand tires that can lead to tire failure, lossof vehicle control, serious injury or death.
WARNING: Always re-inflate tiresto recommended tire pressures beforethe vehicle is operated on-road. Therecommended pressure is located on thetire label or safety certification label,located on the B-pillar, inside the driver'sdoor.
Driving off-road places more stress on yourvehicle than most on-road driving. Afterdriving off-road check for damage to yourvehicle and, if necessary, have your vehiclefixed as soon as possible.
Inspect the underbody of your vehicle bychecking tires, body structure, steering,suspension, and exhaust system fordamage.
Check the radiator for mud and debris andclean as needed.
Remove accumulations of plants or brush.These things could be a fire hazard or hidedamage to the fuel lines, brake hoses, andpropeller shafts.

Rear suspension components may requireregular cleaning with a power washer or athorough rinse with a strong stream ofwater if the vehicle is operated in dusty ormuddy environments. Rear leaf springs orother suspension components may emitsqueaking or popping noises whileoperating the vehicle if particles, such asdirt, rocks, or other debris, are present inthe components.
CLEANING THE EXHAUST
WARNING: Do not modify orremove the exhaust tailpipe. Blockedholes may result in increased exhaustgas temperatures, vehicle damage,property damage or personal injury.
WARNING: Failure to keep theholes in the exhaust tailpipe clean andfree of debris or foreign material mayresult in blocked holes. Blocked holesmay result in increased exhaust gastemperatures, vehicle damage, propertydamage or personal injury.
WARNING: The normal operatingtemperature of the exhaust system isvery high. Never work around or attemptto repair any part of the exhaust systemuntil it has cooled. Use special care whenworking around the diesel oxidationcatalytic converter or the dieselparticulate filter. The diesel oxidationcatalytic converter and the dieselparticulate filter heat up to very hightemperatures after only a short periodof engine operation and remain hot afteryou switch the engine off.
The visible holes in the exhaust tip and theholes under the shield just inboard of theright rear tire(s) are functional. Keep theholes clear of mud, debris or foreignmaterial to maintain proper function of theexhaust system. Clean and remove debrisor foreign material if present as needed.Spraying with a hose during regularwashing of vehicle should help keep holesclean and clear of debris or foreignmaterial.
CLEANING THE INTERIOR

The tires on your vehicle have all-weathertreads to provide traction in rain and snow.However, in some climates, you may needto use snow tires and cables. If you needto use cables, we recommend that you usesteel wheels of the same size andspecification, as cables may chipaluminum wheels.
Follow these guidelines when using snowtires and chains:
•If possible, avoid fully loading yourvehicle.
•Use only SAE Class S chains.
•Install chains securely, verifying thatthe chains do not touch any wiring,brake lines or fuel lines.
•Only install snow chains on the rearaxle.
•For Dual Rear Wheel (DRW) vehicles,only install snow chains on the outerwheel of each pair.
•Drive cautiously. If you hear the chainsrub or bang against your vehicle, stopand retighten the chains. If this doesnot work, remove the chains to preventdamage to your vehicle.
