Tap the Headrest Fold but-
ton to activate/deactivate folding.
Manually push the head restraint until it clicks into position.
WARNING
Do not lower the head restraint if there are passengers in any of the rear seats.
WARNING
The head restraint must be locked in the upright position after it has been folded up.
Folding the rear seat outboard head restraints using the handle
For vehicles with the electric folding function *,
the outboard head restraints can be folded using the handle on the top of the seat (see illustration
.) Note that this method also
folds down the backrests. To fold down only the head restraints, e.g. to improve visibility, use the center display * instead. On models
without electrically folding backrests, the head restraints cannot be moved.

Switching target vehicles with driver support
At certain speeds, vehicles with automatic transmissions and the driver support func- tions Adaptive Cruise Control * and Pilot
Assist * can switch target vehicles.
Switching target vehicles
If the target vehicle ahead turns suddenly, there may be stationary traffic ahead.
When driver support is actively following another vehicle at speeds under 30 km/h
(20 mph) and switches targets from a movingvehicle to a stationary vehicle, driver supportwill brake for the stationary vehicle.
WARNING
When driver support follows another vehi- cle at speeds over approx. 30 km/h
(20 mph) and changes target vehicle –from a moving vehicle to a stationary one –driver support will ignore the stationary
vehicle and instead accelerate to the storedspeed. The driver must then intervene and apply the brakes.
Automatic standby mode when switching targets
Driver support disengages and goes into standby mode if:
your vehicle's speed goes under 5 km/h(3 mph) and driver support cannot deter-mine if the target vehicle is stationary or ifit is another object, e.g. a speed bump.
your vehicle's speed goes under 5 km/h(3 mph) and the vehicle ahead turns sothat driver support no longer has a vehicleto follow.

Adjusting set speed for driver support
It is possible to adjust set speeds for the cruise control, Adaptive Cruise Control * and
Pilot Assist * functions.
: Increases the set speed
: Reduces the set speed
Set speed
–Change a set speed by pressing the
(1) or (2) buttons briefly or by pressing
and holding them:
Brief
press: Each press changes the
speed in +/- 5 km/h (+/- 5 mph) incre- ments.
Press
and hold: Release the button
when the set speed indicator (3) hasmoved to the desired speed.
> The most recently set speed will be stored.
NOTE
For vehicles without Adaptive Cruise Con- trol *, speed instead increases by +/- 1km/h
(+/- 1 mph) each time the button is pressed.
Pressing the accelerator pedalIf speed is increased by depressing the accel- erator pedal while pressing the
(1) button
on the steering wheel, the vehicle's speed when the button is pressed will be stored asthe set speed. Temporarily increasing speed using the accel- erator pedal, e.g. when passing another vehi-cle, will not affect the setting. The vehicle willreturn to the set speed when the acceleratorpedal is released.
Possible speed
Automatic transmission
The driver support functions can follow another vehicle at speeds from a standstill upto 200 km/h (125 mph). Pilot Assist can provide steering assistance from near-stationary speeds up to 140 km/h(87 mph). The lowest speed that can be set is 30 km/h (20 mph). When following another vehicle,ACC can monitor that vehicle's speed andslow your own vehicle down to a standstill,but it is not possible to set speeds lower than30 km/h (20 mph).

Park Assist (PAS 102
) behaves differently
depending on which part of the vehicle is approaching an obstacle.
Front camera
The warning signal has a continuous tone when the obstacle is less than approx. 30 cm (1 ft) from thevehicle.
The Park Assist system's front sensors are automatically activated when the engine isstarted. They are active at speedsbelow 10 km/h (6 mph). The distance monitored extends approx. 80 cm (2.5 ft) in front of the vehicle.
NOTE
The Park Assist system is deactivated when the parking brake is used or when P
is selected on vehicles with automatictransmission.
CAUTION
When installing auxiliary lights: Make sure these do not obscure the sensors – theauxiliary lights could be perceived as anobstacle.
Back
The warning signal has a continuous tone when the obstacle is less than approx. 30 cm (1 ft) from thevehicle.

Location of the backup reader in the tunnel console.
NOTE
When the remote key is placed in the backup reader, make sure that no othervehicle keys, metal objects or electronicdevices (e.g. cellular phones, tablets, lap-tops or chargers) are in the backup reader.Multiple vehicle keys close to each other inthe backup reader can disrupt their func-tionality.
CAUTION
If the engine has not responded after 3 attempts – wait for 3 minutes before star-ting a new attempt. Starting capabilityincreases if the starter battery is given timeto recover.
WARNING
Never remove the remote control key from
the vehicle while driving or the vehicle is being towed.
WARNING
Always remove the remote key from the passenger compartment when youleave the vehicle and make sure theignition is in mode
0.
Always put the gear selector in
P and
apply the parking brake before leavingthe vehicle. Never leave the vehicleunsupervised while the engine is run-ning.
Always open the garage door fully andmake sure that ventilation is very goodbefore starting the engine in a garage.The exhaust fumes produced by thevehicle contain carbon monoxide,which is invisible and odorless but verytoxic.
CAUTION
When starting in cold weather, the automatic transmission may shift up atslightly higher engine speeds than nor-mal until the automatic transmissionfluid reaches normal operating tem-perature.
Do not race a cold engine immediatelyafter starting. This could prevent fluidsfrom properly lubricating vital compo-nents in the engine before it hasreached the proper operating tempera-ture.
The engine should be idling when thegear selector is moved. Never acceler-ate until the gear is fully engaged.Accelerating rapidly before a gear isproperly engaged could lead to harderwear of components.
To help prevent the transmission oilfrom overheating, select
P or N when
idling at a standstill for prolonged peri-ods of time.
