WHAT IS PRE-COLLISION
ASSIST
Pre-collision assist detects and warns ofapproaching hazards in the roadway. Ifyour vehicle is rapidly approaching anotherstationary vehicle, a vehicle traveling in thesame direction as yours, or a pedestrianwithin your driving path, the systemprovides multiple levels of assistance tohelp avoid a collision.
HOW DOES PRE-COLLISION
ASSIST WORK
The system warns the driver of potentialhazards by providing three levels ofassistance.
If your vehicle is rapidly approachingpotential hazards the system provides thefollowing levels of functionality:
1.Alert.
2.Brake Support.
3.Automatic Emergency Braking.
Alert: When active, a flashingvisual warning appears and anaudible warning tone sounds.
Brake Support: The system is designedto help reduce the impact speed bypreparing the brakes for rapid braking. Thesystem does not automatically apply thebrakes. If you press the brake pedal, thesystem could apply additional braking upto maximum braking force, even if youlightly press the brake pedal.
Automatic Emergency Braking:Automatic emergency braking mayactivate if the system determines that acollision is imminent.
Note:If you perceive the pre-collision assistalerts as being too frequent or disturbing,then you can reduce the alert sensitivity.Setting the low sensitivity would result infewer and later warnings of a potentialforward collision. The manufacturerrecommends using the high sensitivitysetting where possible.
Note:Automatic emergency brakingperformance is not affected by thesensitivity setting.
Each system has various levels ofdetection capabilities. See Pre-CollisionAssist Limitations (page 278).

WARNING: System performancecould be reduced in situations where thevehicle camera has limited detectioncapability. These situations include butare not limited to direct or low sunlight,vehicles at night without tail lights,unconventional vehicle types,pedestrians or cyclists with complexbackgrounds, running pedestrians or fastmoving cyclists, partly obscuredpedestrians or cyclists, pedestrians orcyclists that the system cannotdistinguish from a group. Failure to takecare may result in the loss of control ofyour vehicle, personal injury or death.
PRE-COLLISION ASSIST
LIMITATIONS
Pre-collision assist depends on thedetection ability of its camera and sensors.Any obstructions or damage to these areascan limit detection or prevent the systemfrom functioning. See Locating thePre-Collision Assist Sensors (page 279).
The system is active at 3 mph (5 km/h)and above.
Note:Brake support and automaticemergency braking are active up to themaximum speed of the vehicle.
Pedestrian Detection Limitations
Pedestrian detection is active at speedsup to 50 mph (80 km/h).
Pedestrian detection functions optimallywhen detected hazards are clearlyidentifiable. System performance mayreduce in situations where pedestrians arerunning, partly obscured, have a complexbackground, or cannot be distinguishedfrom a group.
Cyclist Detection Limitations
Cyclist detection is active at speeds up to50 mph (80 km/h).
Cyclist detection functions optimally whendetected hazards are clearly identifiable.The system’s detection level may be lessin situations where cyclists are moving fast,partly hidden, have a complex background,or the system cannot distinguish the cyclistfrom a group.

EVASIVE STEERING ASSIST
WHAT IS EVASIVE STEERINGASSIST
If your vehicle is rapidly approaching a roaduser, evasive steering assist helps you steeraround the road user.
After you turn the steering wheel in anattempt to avoid a crash with the roaduser, the system applies additional steeringtorque to help you steer around the roaduser. After you pass the road user, thesystem applies steering torque when youturn the steering wheel to steer back intothe lane. The system deactivates after youfully pass the road user.
Note:Road users are defined aspedestrians or bicyclists in your vehicle'spath or another stationary vehicle in thesame lane or a vehicle traveling in the samelane in the same direction as you. SeePre-Collision Assist Precautions (page277).
EVASIVE STEERING ASSISTLIMITATIONS
Evasive steering assist only activates whenall the following occur:
•Automatic emergency braking andevasive steering assist are on.
•The system detects a road user aheadand starts to apply the brakes.
•You significantly turn the steeringwheel to steer around a road user.
Note:Evasive steering assist does notautomatically steer around a road user. Ifyou do not turn the steering wheel, evasivesteering assist does not activate.
Note:Evasive steering assist does notactivate if the distance to the road userahead is too small and the system cannotavoid a crash.

COLD WEATHER
PRECAUTIONS
The functional operation of somecomponents and systems can be affectedat temperatures below approximately-13°F (-25°C).
DRIVING ON SNOW AND ICE
WARNING: If you are driving inslippery conditions that require tirechains or cables, then it is critical thatyou drive cautiously. Keep speeds down,allow for longer stopping distances andavoid aggressive steering to reduce thechances of a loss of vehicle controlwhich can lead to serious injury or death.If the rear end of your vehicle slides whilecornering, steer in the direction of theslide until you regain control of yourvehicle.
On ice and snow, you should drive moreslowly than usual. Your vehicle has a fourwheel anti-lock brake system, do not pumpthe brake pedal. See Anti-Lock BrakingSystem Limitations (page 197).
BREAKING-IN
You need to break in new tires forapproximately 300 mi (480 km). Duringthis time, your vehicle may exhibit someunusual driving characteristics.
PERFORMANCE VEHICLE
PRECAUTIONS
•Verify correct tire pressures.
•Inspect wheels and tires for wear anddamage. Replace any damaged wheelsor tires.
•Do not operate your vehicle at highspeeds with more than two passengersor while carrying cargo.
•It is recommended to cross speedbumps or driveway inclines slowly andat a 45° angle to reduce the risk ofvehicle damage.
•Do not drive through car washes withthe vehicle heavily loaded withpassengers or luggage.
•Use only commercial car washeswithout mechanical tracks or handwash to avoid potential damage.
•Put your vehicle in stay in neutral modewhen entering an automatic car wash.See Selecting a Drive Mode (page260).
DRIVING IN SPECIAL
CONDITIONS
EMERGENCY MANEUVERS
In an unavoidable emergency where youmust make a sudden sharp maneuver, turnthe steering wheel only as rapidly and asfar as required to avoid the emergency.Apply smooth pressure to the acceleratorpedal or brake pedal as needed. Avoidabrupt steering, acceleration and brakingchanges. Abrupt changes could increasethe risk of vehicle roll over, loss of vehiclecontrol and personal injury. If possible, useany available road surfaces to bring yourvehicle under control.

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.
ELECTRIC VEHICLE
MAXIMIZING YOUR DRIVINGRANGE

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.
