WARNING: The system only warnsof vehicles detected by the radar sensor.In some cases there may be no warningor a delayed warning. Apply the brakeswhen necessary. Failure to follow thisinstruction could result in personal injuryor death.
Note:When you are following a vehicle andyou switch on a direction indicator, adaptivecruise control may provide a smalltemporary acceleration to help you pass.
Note:The brakes may emit noise whenapplied by the system.
When a vehicle ahead of you enters thesame lane or a slower vehicle is ahead inthe same lane, the vehicle speed adjuststo maintain a preset gap distance. Avehicle graphic illuminates in theinstrument cluster.
Your vehicle maintains a consistent gapfrom the vehicle ahead until any of thefollowing occur:
•The vehicle in front of you acceleratesto a speed above the set speed.
•The vehicle in front of you moves outof the lane you are in.
•Your vehicle speed falls below 12 mph(20 km/h).
•You set a new gap distance.
The system applies the brakes to slow yourvehicle to maintain a safe gap distancefrom the vehicle in front. The system onlyapplies limited braking. You can overridethe system by applying the brakes.
If the system determines that its maximumbraking level is not sufficient, an audiblewarning sounds, a message appears in theinformation display and an indicatorflashes when the system continues tobrake. Take immediate action.
Setting the Gap Distance
You can decrease or increase the distancebetween your vehicle and the vehicle infront by pressing the gap control.
Press and release to decreasethe gap distance.
Press and release to increase thegap distance.
The selected gap appears in theinformation display as shown by the barsin the image.
Note:The gap setting is time dependentand therefore the distance adjusts with yourvehicle speed.
Note:It is your responsibility to select a gapappropriate to the driving conditions.

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

If the time gap to a preceding vehicle issmall, a red visual indication displays.
Note:Distance indication and alertdeactivates and the graphics do not displaywhen adaptive cruise control is active.
Adjusting the Pre-Collision AssistSettings
You can adjust the following settings byusing the instrument cluster displaycontrols. See General Information (page64).
•You can change alert and distancealert sensitivity to one of three possiblesettings.
•You can switch distance indication andalert on or off.
•If required, you can switch activebraking on or off.
•If required, you can switch thepre-collision assist feature on or off.
Note:Active braking automatically turnson every time you switch the ignition on.

Severe Climates
If you drive in extremely cold climates:
•It may be necessary to increase thecoolant concentration above 50%.
•A coolant concentration of 60%provides improved freeze pointprotection. Coolant concentrationsabove 60% decrease the overheatprotection characteristics of thecoolant and may cause enginedamage.
If you drive in extremely hot climates:
•You can decrease the coolantconcentration to 40%.
•Coolant concentrations below 40%decrease the freeze and corrosionprotection characteristics of thecoolant and may cause enginedamage.
Vehicles driven year-round in non-extremeclimates should use prediluted coolant foroptimum cooling system and engineprotection.
Coolant Change
Change the engine coolant at the specificmileage intervals listed in scheduledmaintenance. See Capacities andSpecifications (page 226).
Fail-Safe Cooling
Fail-safe cooling allows you to temporarilydrive your vehicle before any incrementalcomponent damage occurs. The fail-safedistance depends on ambienttemperature, vehicle load and terrain.
How Fail-Safe Cooling Works
If the engine begins to overheat, thecoolant temperature gauge moves towardthe red zone.
A warning lamp illuminates anda message may appear in theinstrument cluster display.
If the engine reaches a presetover-temperature condition, itautomatically switches to alternatingcylinder operation. Each disabled cylinderacts as an air pump and cools the engine.
When this occurs, your vehicle stilloperates, however:
•Engine power is limited.
•The air conditioning system turns off.
Continued operation increases the enginetemperature, causing the engine tocompletely shut down. Your steering andbraking effort increases in this situation.
When the engine temperature cools, youcan restart the engine. Have your vehiclechecked as soon as possible to minimizeengine damage.
When Fail-Safe Mode Is Activated
WARNING: Fail-safe mode is foruse during emergencies only. Operateyour vehicle in fail-safe mode only aslong as necessary to bring your vehicleto rest in a safe location and seekimmediate repairs. When in fail-safemode, your vehicle will have limitedpower, will not be able to maintainhigh-speed operation, and maycompletely shut down without warning,potentially losing engine power, powersteering assist, and power brake assist,which may increase the possibility of acrash resulting in serious injury.

2024 E-Series (TE4) Canada/United States of America, enUSA, Edition date: 202210, First-PrintingMaintenanceE103308 E67028

WARNING: Do not remove thecoolant reservoir cap when the engine ison or the cooling system is hot. Wait 10minutes 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.
Your vehicle has limited engine powerwhen in the fail-safe mode, drive yourvehicle with caution. Your vehicle does notmaintain high-speed operation and theengine may operate poorly.
Remember that the engine is capable ofautomatically shutting down to preventengine damage. In this situation:
1.Pull off the road as soon as safelypossible and switch the engine off.
2.If you are a member of a roadsideassistance program, contact yourroadside assistance service provider.
3.If this is not possible, wait a shortperiod for the engine to cool.
4.Check the coolant level. If the coolantlevel is at or below the minimum mark,add prediluted coolant immediately.
5.When the engine temperature cools,you can restart the engine. Have yourvehicle checked as soon as possible tominimize engine damage.
Note:Driving your vehicle without repairincreases the chance of engine damage.
Engine Coolant TemperatureManagement (If Equipped)
WARNING: To reduce the risk ofcrash and injury, be prepared that thevehicle speed may reduce and thevehicle may not be able to acceleratewith full power until the coolanttemperature reduces.
If you tow a trailer with your vehicle, theengine may temporarily reach a highertemperature during severe operatingconditions, for example ascending a longor steep slope in high ambienttemperatures.
At this time, you may notice the coolanttemperature gauge moves toward the redzone and a message may appear in theinstrument cluster display.
You may notice a reduction in vehiclespeed caused by reduced engine power tomanage the engine coolant temperature.Your vehicle may enter this mode if certainhigh-temperature and high-load conditionstake place. The amount of speedreduction depends on vehicle loading,grade and ambient temperature. If thisoccurs, there is no need to pull off theroad. You can continue to drive yourvehicle.
The air conditioning may automaticallyturn on and off during severe operatingconditions to protect the engine fromoverheating. When the coolanttemperature returns to the normaloperating temperature, the air conditioningturns on.
If the coolant temperature gauge movesfully into the red zone, or if the coolanttemperature warning or service enginesoon messages appear in your instrumentcluster display, do the following:
169
2024 E-Series (TE4) Canada/United States of America, enUSA, Edition date: 202210, First-PrintingMaintenance

1.Pull off the road as soon as safelypossible and shift the transmission intopark (P).
2.Leave the engine running until thecoolant temperature gauge needlereturns to the normal position. If thetemperature does not drop afterseveral minutes, follow the remainingsteps.
3.Switch the engine off and wait for it tocool. Check the coolant level.
4.If the coolant level is at or below theminimum mark, immediately addprediluted coolant.
5.If the coolant level is normal, restartthe engine and continue driving.
AUTOMATIC TRANSMISSION
FLUID CHECK
Have an authorized dealer check andchange the transmission fluid and filter atthe correct service interval. SeeScheduled Maintenance (page 249).
Do not use supplemental transmissionfluid additives, treatments or cleaningagents. The use of these materials mayaffect transmission operation and resultin damage to internal transmissioncomponents.
Checking Automatic TransmissionFluid
For scheduled intervals of the fluid checksand changes, See ScheduledMaintenance (page 249). Yourtransmission does not consume fluid.However, if the transmission is not workingproperly, for example, if the transmissionslips or shifts slowly, or if you notice somesign of fluid leakage, check the fluid levelas soon as possible.
Automatic transmission fluid expandswhen warmed. Obtain an accurate readingas follows :
1.Drive the vehicle approximately 19 mi(30 km) to reach normal operatingtemperature via the transmission fluidtemperature gauge on the instrumentcluster.
2.Park the vehicle on a level surface andengage the parking brake.
3.With the engine running, parking brakeengaged and your foot on the brakepedal, move the gearshift lever throughall of the gear ranges. Allow sufficienttime for each gear to engage.
4.Put the transmission in park (P) andleave the engine running.
5.Remove the dipstick, wiping it cleanwith a clean, dry, lint free rag.
6.Install the dipstick, fully seating it in thefiller tube.
7.Remove the dipstick and inspect thefluid level. The fluid should be in thedesignated area for normal operatingtemperature.
Low Fluid Level
Do not drive the vehicle if there is noindication of fluid on the dipstick and theambient temperature is above 50°F(10°C).
