• Unstable loads can be secured to the loadanchoring eyelets with straps or web lash-ings to help keep them from shifting.
• Stop the engine and apply the parking brakewhen loading or unloading long objects. Thegear selector can be knocked out of positionby long loads, which could set the vehicle inmotion.
WARNING
•
Stop the engine, put the gear selector in P
, and apply the parking brake when
loading or unloading long objects.
• The vehicle's driving characteristics may change depending on the weight and dis-tribution of the load.
• A 44-pound (20 kg) object produces aforce of 2,200 pounds (1,000 kg) in ahead-on collision at 30 mph (50 km/h).
• The cargo area and rear seat should notbe loaded to a level higher than 2 in.(5 cm) below the upper edge of the rearside windows. Objects placed higher thanthis level could impede the function ofthe Inflatable Curtain.
WARNING
•
Cover sharp edges on long loads to help prevent injury to occupants. Secure theload to help prevent shifting during sud-den stops.
• Always secure large and heavy objectswith a seat belt or cargo retaining straps.
• Always secure the load to help prevent itfrom moving in the event of sudden stops.
• Switch off the engine, apply the parking brake and put the gear selector in
P
when loading and unloading the vehicle.

Pilot Assistauto-hold brake function
At certain speeds, Pilot Assist provides braking effect.
Stop-and-go drivingDuring brief stops in slow-moving traffic or att traffic lights where the vehicle is not stopped formore than 3 seconds, driving will resume auto-matically. If it takes more than 3 seconds for thevehicle ahead to begin moving again, Pilot Assistwill go into standby mode and the auto-holdbrake function will activate. The driver will then have to reactivate Pilot Assist as follows:
–• Press the button
• Press the accelerator pedal
> Pilot Assist will resume following the vehi- cle ahead if it begins to move within approx. 6 seconds.
NOTE
• Pilot Assist can keep the vehicle station- ary for max. 5 minutes, after which theparking brake will be set and Pilot Assistwill go into standby mode.
• The parking brake must be releasedbefore Pilot Assist can be reactivated.
Deactivating the auto-hold brake functionIn certain situations, auto-hold will be deactivated when the vehicle is at a standstill and Pilot Assistwill go into standby mode. This means that the brakes will be released and the vehicle can begin to roll. The driver must actively apply the brakes to keep the vehicle at a standstill. This can occur in the following situations: • the driver presses the brake pedal
• the parking brake is set
• the gear selector is moved to the
P, N or R
positions
• the driver puts Pilot Assist in standby mode
Automatically setting the parking brakeIn certain situations, the parking brake is set automatically to help keep the vehicle at a stand-still. This occurs if:
• the driver unbuckles the seat belt or opens the door
• Pilot Assist has kept the vehicle at a stand-still for more than approx. 5 minutes
• the engine is turned off
• the brakes overheat

Pilot Assist limitations
Pilot Assist functionality may be limited in certain situations.

DRIVER SUPPORT
* Option/accessory, for more information, see Introduction.267
WARNING
•Pilot Assist is not a collision avoidance system. The driver is always responsiblefor applying the brakes if the system doesnot detect another vehicle.
• Do not use Pilot Assist in demandingdriving conditions such as city driving orother heavy traffic situations, in slipperyconditions, when there is a great deal ofwater or slush on the road, during heavyrain or snow, in poor visibility, on windingroads or on highway on- or off-ramps.
• Pilot Assist uses the vehicle's cameraand radar sensor, which have limitations.
Pilot Assist may deactivate or not function optimally if:
• the lane's side market lines are missing, badly faded or cross each other.
• the division of lanes is not clear, e.g.,when a line divides or merges withanother, at exits or if there are many roadsigns/markers.
• if there are edges or other lines on ornear the lane, e.g., curbs, cracks, repairedareas, sharp shadows, etc.
• the lane is narrow or winding.
• the weather conditions (rain, snow, fog,slush, poor visibility, backlighting, etc).
The driver should also be aware that Pilot Assist has the following limitations:
• High curbs, barriers and temporary obsta- cles (cones, barriers etc) may not bedetected or could be detected incorrectlyas side marker lines, which may create arisk of collision. The driver must ensure asafe distance to these obstacles.
• The camera or radar sensor may not beable to detect objects if there are pot-holes or if there are stationary objectspartially or completely blocking the road.
• Pilot Assist does not "see" pedestrians,animals, etc.
• Pilot Assist's steering capacity is limitedand may not always be able to help thedriver keep the vehicle in the lane.
The driver can always take action to override Pilot Assist.
Steep roads and/or heavy loadsPilot Assist is primarily intended for use on rela-tively level roads. The function may not be able tomaintain the correct time interval to the vehicleahead on when driving down steep hills, when thevehicle is transporting a heavy load or if it is tow-ing a trailer. The driver should be attentive andprepared to apply the brakes in these situations.

Other Adaptive Cruise Control (ACC) functionsACC is an optional system designed to assist
the driver by maintaining a set speed or a set time interval to the vehicle ahead.
ACC has several supplementary functions:
• Changing target vehicles
• Automatic standby mode when changing tar- gets
• Auto-hold brake function
• Deactivation of the auto-hold brake function
• Automatically setting the parking brake
Changing target vehicles
If the target vehicle turns suddenly, there may be a sta- tionary vehicle ahead
When ACC is actively following another vehicle at speeds
under 20 mph (30 km/h) and changes
targets from a moving vehicle to a stationary one, the system will brake for the stationary vehicle.
WARNING
If ACC changes targets from a moving vehicle to a stationary one at speeds above 20 mph
(30 km/h), the system will not react to the
stationary vehicle and will accelerate to the previously set speed. The driver must actively apply the brakes to slow/stop the vehicle.
Automatic standby mode when changing targets
ACC disengages and goes into standby mode if:
• your vehicle's speed goes below approx. 3 mph (5 km/h) and ACC cannot determine ifthe target object is a stationary vehicle orsome other type of object such as a speedbump, etc
• the vehicle's speed goes below approx.3 mph (5 km/h) and the vehicle aheadchanges lanes or turns so that ACC nolonger has a target vehicle to follow
Auto-hold brake functionIn slow-moving, stop-and-go traffic or when stop- ped at a traffic light, driving will resume automati-cally if the vehicle is not stopped for more thanapprox. 3 seconds. If it takes more than3 seconds for the vehicle ahead to begin movingagain, ACC will go into standby mode and theauto-hold brake function will activate.
–The driver will then have to reactivate ACC in one of the following ways:
• Press the
button on the left-side
steering wheel keypad
• Press the accelerator pedal
> ACC will resume following the vehicle ahead (target vehicle) if it begins to move
within approx. 6 seconds.
NOTE
ACC can keep the vehicle at a standstill for up to 5 minutes, after which the parking brakewill be set and ACC will go into standbymode. The parking brake has to be released before ACC can be reactivated.
