The brake support system assists you inreducing any collision speed by pre-chargingthe brakes. If the risk of collision continuesto increases after the audio-visual warning,the brake support prepares the brake systemfor rapid braking. The system does notautomatically activate the brakes, but if thebrake pedal is pressed even lightly, thebrakes apply full stopping power.
Using the Collision Warning System
WARNING
The collision warning system's brakesupport reduces collision speed onlyif you brake your vehicle before any collision.You must press your brake pedal as youwould in any typical braking situation.
You can use your information display controlto adjust the warning system's sensitivity toany one of three possible settings. SeeGeneral Information (page 109).
Note:When possible, the manufacturerrecommends using the highest sensitivitysetting. If warnings are too frequent, you canreduce your system's sensitivity. Reducedsensitivity causes fewer and later systemwarnings. See General Information (page109).
Blocked Sensors
If a blocked sensor message appears in theinformation display, dirt, water, or an objectis blocking the sensor. The sensor is locatedbehind a cover near the driver side of thelower grille. If anything blocks the sensor,your vehicle cannot see through the sensor,and the collision warning system will notwork. Possible causes for the blocked sensormessage and corrective actions are listedbelow.

TOWING A TRAILER
WARNINGS
Towing trailers beyond themaximum recommended grosstrailer weight exceeds the limit of yourvehicle and could result in enginedamage, transmission damage,structural damage, loss of vehiclecontrol, vehicle rollover and personalinjury.
Do not exceed the GVWR or theGAWR specified on the certificationlabel.
Note: See Recommended TowingWeights (page 243).
Your vehicle may have electrical items,such as fuses or relays, related totowing. See Fuses (page 268).
Your vehicle's load capacity designationis by weight, not by volume, so youcannot necessarily use all availablespace when loading a vehicle or trailer.
Towing a trailer places an extra load onyour vehicle's engine, transmission, axle,brakes, tires and suspension. Inspectthese components periodically during,and after, any towing operation.
Load Placement
To help minimize how trailer movementaffects your vehicle when driving:
•Load the heaviest items closest tothe trailer floor.
•Load the heaviest items centeredbetween the left and right side trailertires.
•Load the heaviest items above thetrailer axles or just slightly forwardtoward the trailer tongue. Do notallow the final trailer tongue weightto go above or below 10-15% of theloaded trailer weight.
•Select a ball mount with the correctrise or drop and load capacity. Whenboth the loaded vehicle and trailerare connected, the trailer frameshould be level, or slightly angleddown toward your vehicle, whenviewed from the side.
When driving with a trailer or payload, aslight takeoff vibration or shudder maybe present due to the increased payloadweight. Additional information regardingproper trailer loading and setting yourvehicle up for towing is located inanother chapter of this manual. SeeLoad Limit (page 237).
You can also find information in the RV& Trailer Towing Guide available at yourauthorized dealer, or online.

How Fail-Safe Cooling Works
If the engine begins to overheat, the enginecoolant temperature gauge will move to thered (hot) area and:
A high engine temperaturemessage will appear in theinformation display.
The service engine soon indicatorwill light.
If the engine reaches a presetover-temperature condition, the engine willautomatically switch to alternating cylinderoperation. Each disabled cylinder acts as anair pump and cools the engine.
When this occurs the vehicle will still operate.However:
•The engine power will be limited.
•The air conditioning system will bedisabled.
Continued operation will increase the enginetemperature and the engine will completelyshut down, causing steering and brakingeffort to increase.
Once the engine temperature cools, theengine can be re-started. Take your vehicleto an authorized dealer as soon as possibleto minimize engine damage.
When Fail-Safe Mode Is Activated
WARNINGS
Fail-safe mode is for use duringemergencies only. Operate yourvehicle in fail-safe mode only as long asnecessary to bring your vehicle to rest in asafe location and seek immediate repairs.When in fail-safe mode, the vehicle will havelimited power, will not be able to maintainhigh-speed operation, and may completelyshut down without warning, potentially losingengine power, power steering assist, andpower brake assist, which may increase thepossibility of a crash resulting in seriousinjury.
Never remove the coolant reservoircap while the engine is running or hot.
You have limited engine power when in thefail-safe mode, so drive your vehicle withcaution. Your vehicle will not be able tomaintain high-speed operation and theengine will run rough. Remember that theengine is capable of completely shuttingdown automatically to prevent enginedamage, therefore:
1. Pull off the road as soon as safelypossible and switch the engine off.
2. Arrange for your vehicle to be taken toan authorized dealer.
3.If this is not possible, wait a short periodfor the engine to cool.
4. Check the coolant level and replenish iflow.
5.Re-start the engine and take your vehicleto an authorized dealer.
Note:Driving your vehicle without repairingthe engine problem increases the chance ofengine damage. Take your vehicle to anauthorized dealer as soon as possible.
