DRIVING THROUGH MUD ANDWATER
Mud
Be cautious of sudden changes in vehiclespeed or direction when you are driving inmud. Even all-wheel drive and four-wheeldrive vehicles can lose traction in mud. Ifyour vehicle slides, steer in the direction ofthe slide until you regain control of yourvehicle. After driving through mud, cleanoff residue stuck to rotating driveshaftsand tires. Excess residue can cause animbalance that could damage drivecomponents.
Note:If your vehicle gets stuck in mud, itcould be rocked out by shifting betweenforward and reverse gears, stoppingbetween shifts in a steady pattern. Presslightly on the accelerator in each gear.
Water
If you must drive through water approachit cautiously. See Driving ThroughShallow Water (page 303).
DRIVING ON HILLY OR SLOPINGTERRAIN
Although natural obstacles could make itnecessary to travel diagonally up or downa hill or steep incline, you should try to drivestraight up or straight down.
Note:Avoid turning on steep slopes or hills.A danger lies in losing traction, slippingsideways and possible vehicle roll over.Whenever driving on a hill, determinebeforehand the route you can use. Do notdrive over the crest of a hill without seeingwhat conditions are on the other side. Donot drive in reverse over a hill without theaid of an observer.
Apply just enough power to the wheels toclimb the hill. Too much power causes thetires to slip, spin or lose traction, and youcould lose control of your vehicle. Whendescending a steep hill, do not descendthe hill in neutral. Avoid sudden hardbraking to keep the front wheels rolling andto maintain your vehicle's steering.
Note:Your vehicle has anti-lock brakes,apply the brakes steadily. Do not pump thebrakes.
DRIVING IN SAND
When driving over sand, try to keep all fourwheels on the most solid area of the trail.Shift to a lower gear and drive steadilythrough the terrain. Apply the acceleratorslowly and avoid excessive wheel slip. Donot drive your vehicle in deep sand for anextended period of time. This couldoverheat the system. A message appearsin the information display. See All-WheelDrive – Information Messages (page196).
Note:If your vehicle gets stuck in sand, itcould be rocked out by shifting betweenforward and reverse gears, stoppingbetween shifts in a steady pattern. Presslightly on the accelerator in each gear.

Note:Some of these components areunderneath the luggage compartment coverand cannot be seen unless the cover isremoved. See Installing and Removingthe Luggage Compartment Cover (page297).
CHECKING THE COOLANT
WARNING: Do not remove thecoolant reservoir cap when the vehicleis on or the cooling system is hot. Wait10 minutes for the cooling system to cooldown. Cover the coolant reservoir capwith a thick cloth to prevent thepossibility of scalding and slowly removethe cap. Failure to follow this instructioncould result in personal injury.
WARNING: Do not put coolant inthe windshield washer reservoir. Ifsprayed on the windshield, coolant couldmake it difficult to see through thewindshield.
WARNING: Do not add coolantfurther than the MAX mark.
Note: Coolant expands when it is hot. Thelevel may extend beyond the MAX mark.
Your vehicle has a battery cooling systemand a motor electrical cooling system. SeeUnder Hood Overview (page 325). Theluggage compartment covers need to beremoved in order to access the reservoirs.See Installing and Removing theLuggage Compartment Cover (page 297).
When the electric motor is cold, check theconcentration and level of the coolant atthe intervals listed in the scheduledmaintenance information. See ScheduledMaintenance (page 410).
Maintain coolant concentration within48% to 50%, which equates to a freezepoint between -29–-35°F (-34–-37°C).Check coolant concentration using arefractometer. We do not recommend theuse of hydrometers or coolant test stripsfor measuring coolant concentration.
Adding Coolant
It is very important to use predilutedcoolant approved to the correctspecification in order to avoid plugging thesmall passageways in the electric motorcooling system. See Cooling SystemCapacity and Specification (page 366).
Do not mix different colors or types ofcoolant in your vehicle. Mixing of coolantsor using an incorrect coolant may harm theelectric motor or cooling systemcomponents and may cause damage thatthe vehicle warranty may not cover.
Note:Automotive fluids are notinterchangeable.
Note:Do not use stop leak pellets, coolingsystem sealants, or non-specified additivesas they can cause damage to the electricmotor cooling or heating systems.
