WARNING: Some situations andobjects prevent hazard detection. Forexample low or direct sunlight, inclementweather, unconventional vehicle types,and pedestrians. Apply the brakes whennecessary. Failure to follow thisinstruction could result in the loss ofcontrol of your vehicle, personal injury ordeath.
WARNING: Take additional care ifyour vehicle is heavily loaded or you aretowing a trailer. These conditions couldresult in reduced performance of thissystem. Failure to follow this instructioncould result in the loss of control of yourvehicle, personal injury or death.
WARNING: The system cannothelp prevent all crashes. Do not rely onthis system to replace driver judgmentand the need to maintain a safe distanceand speed.
Using the Pre-Collision AssistSystem
The pre-collision assist system is active atspeeds above 3 mph (5 km/h). Pedestriandetection functions at speeds up to50 mph (80 km/h).
If your vehicle is rapidly approachinganother stationary vehicle or a vehicletraveling in the same direction as yours,the system provides three levels offunctionality:
•Alert.
•Brake support.
•Active braking.
Alert: When active, a flashing visualwarning appears and an audible warningtone sounds.
Brake support: Helps reduce the impactspeed by preparing the brakes for rapidbraking. The system does notautomatically apply the brakes. If you pressthe brake pedal, the system could applyadditional braking up to maximum brakingforce, even if you lightly press the brakepedal.
Active braking: May activate if the systemdetermines that a collision is imminent.The system may help the driver reduceimpact damage or avoid the crashcompletely.
Note:If you perceive pre-collision assistalerts as being too frequent you can reducethe alert sensitivity, though themanufacturer recommends using thehighest sensitivity setting where possible.Setting lower sensitivity would lead to fewerand later system warnings.
Distance Indication and Alert
Provides the driver with a graphicalindication of the time gap to otherpreceding vehicles traveling in the samedirection. The distance indication and alertscreen in the instrument cluster displayshows one of the following graphics.
119
2024 E-Series (TE4) Canada/United States of America, enUSA, Edition date: 202210, First-PrintingDriving AidsE156130 E255268

When used properly, the trailer brakecontroller assists in smooth and effectivetrailer braking by powering the trailer’selectric or electric-over-hydraulic brakeswith a proportional output based on thetowing vehicle’s brake pressure.
The controller user interface consists ofthe following:
A: + and - (Gain adjustment buttons):Pressing these buttons adjusts thecontroller's power output to the trailerbrakes in 0.5 increments. You can increasethe gain setting to 10.0 (maximum trailerbraking) or decrease it to 0 (no trailerbraking). The gain setting displays in themessage center.
The controller shows gain setting, outputbar graph, and trailer connectivity statusin the information display. They appear inthe information display as follows:
•Trailer Brake Controller Gain (withouttrailer connected): Shows the currentgain setting during a given ignition cycleand when adjusting the gain. This alsodisplays if you use the manual controllever or make gain adjustments withno trailer connected.
•Trailer Brake Controller Gain Output:Displays when you push your vehicle'sbrake pedal, or upon use of the manualcontrol. Bar indicators illuminate in theinformation display to indicate theamount of power going to the trailerbrakes relative to the brake pedal ormanual control input. One bar indicatesthe least amount of output; six barsindicate maximum output.
•Trailer Connected: Displays when thesystem senses a correct trailer wiringconnection (a trailer with electric trailerbrakes) during a given ignition cycle.
•Trailer Disconnected: Displays,accompanied by a single audible tone,when the system senses a trailerconnection and then a disconnection,either intentional or unintentional,during a given ignition cycle. It alsodisplays if a truck or trailer-wiring faultoccurs causing the trailer to appeardisconnected. This message alsodisplays if you use the manual controllever without a trailer connected.
B: Manual control lever: Slide the controllever to the left to switch on the trailer'selectric brakes independent of the towvehicle's. See Procedure for AdjustingGain section for instructions on proper useof this feature. If you use the manualcontrol while the brake is also applied, thegreater of the two inputs determines thepower sent to the trailer brakes.
