& WARNING (co ntinued )
• When parking on hills, always turn the wheel s so that the front
wheels will fir st roll into the curb, if the vehicle should start to
roll.
• Never allow anyone -especially small children -to remain in
the vehicle when it i s locked. Locked door s make it more d ifficult
for rescuer s to acce ss the pa ssenger compartment in the event of
an emergency. Danger to life!
• Never leave children un supervised in the vehicle . Children
could release the parking brake or mo ve the gearshift lever out of
gear . The vehicle could start to roll away and cause an accident .
• No matter what the season is , the temperature in a parked
vehicle can reach dangerou s levels.
0 Note
• Please exerc ise care when you park your vehicle in parking areas
with park ing barriers or c urbs. Pa rking barriers and c urbs vary in
height and co uld damage you r bumpe r and related componen ts as
the front of your vehicle moves over a barrier or curb that is too h igh,
as you par k or a s yo u back out of a p arking s pot. I n or der to be s ure
that no such damage can occ ur, yo u may wish to stop short of having
t he fro nt t ires of you r ca r tou ch the pa rk in g barrier or curb.
• Please a lso exerc ise except ional care when yo u drive up or down
s t eep ram ps or drive ove r curb s or other obst acles, for which t he
vehicle is not designed, because components of the vehicle close to
t he g roun d, s uch as bumpe r cove rs, spoilers and s uspension and

For this, t he vehicle mus t be st andi ng in u phill driving direc

After releas ing the brake pedal, the brake power is he ld for a
brief
moment to preve nt the vehi cle from rolling back when s tarting. At
this time, you can easi ly begin to move your vehicle .
& WARNING
• If you did not begin moving immediately after releasing the
brake pedal, under certain circumstances, the vehicle wou ld begin
to roll backward. Depress the brake pedal immediately or engage
the parking brake .
• Should the engine stall , depress the brake pedal immediately
or engage the parking brake .
• In order to prevent the vehicle from rolling back unintention
ally when starting in stop-and-go traffic, keep the brake pedal
depressed for a few seconds before driving off .
• When you leave the vehicle -even if only briefly - , sw itch off
the ignition and make sure to remove the ignition key . Also
engage the parking brake to prevent your vehicle from rolling
unintentionally. This particularly applies if children are left in the
vehicle -danger of accident! •

Change speed in increments of 1 mph (1 km/h) by lightly pressing the
lever. If you keep the lever pressed down, you w ill alter your speed in
5 mph (10 km/h) increments.
You can also press the accelerator pedal down to increase your speed,
e .g . if you want to pass someone. The speed you saved earlier will
resume as soon as you release the accelerator pedal.
If, however, you exceed your saved speed by 5 mph (10 km/h) for
longer than 5 minutes, the cruise control will turn off temporarily .
The symbo l will go out but the saved speed will be retained. •
Presetting your speed
You can preset your desired speed while the vehicle is not

& WARNING (continued)
the veh icle s afely when you follow another vehicle too closely.
Alway s rem ember that the Adaptive Cruise Control has a braking
powe r that is only about 30 % of the vehicle's maximum braking
ability. The automatic braking function cannot bring th e ve hicle to
a sudden or emergency stop . Always be prepared to brake and take
evasive action to avoid collisions and other accident situations .
• Never allow the closing speed between you and other vehicles
to be so high that the Adaptive Cruise Control may not be able to
slow your vehicle safely. If closing speed is too h igh, you must
apply the brake s your self to reduce the ri sk of a rear-end cra sh .
• Never rest your foot on the accelerator pedal , especially when
the Adaptive Crui se Control is being used. Pressure on the acceler
ator will overr ide the ACC braking function and prevent the brakes
from being applied when ACC detects a situation when the brake s
must be applied .
• Never u se Adaptive Cruise Control when you cannot drive safely
at a steady speed, including on city streets , on winding roads or
when road conditions are poor (for example , on ice, gravel, in fog ,
heavy rain or on wet roads that increase the risk of hydroplaning ).
• The radar sensor's
vi sion can be redu ced by rain, snow and
heavy road spray. These and similar conditions can prevent vehi
cle s up ahead from being accurately detected and in some cases
they may not be detected at all. Do not use ACC when the radar
sensors cannot accurately detect vehicles mo ving ahead of you in
traffic .
• Always turn off Adaptive Crui se Control when entering turn
lanes, exit lanes and con struction zones or in similar situat ions
because the vehicle will automatically accelerate to the stored
speed when the road ahead i s clear .
• To prevent unintended operation , always switch ACC off when
it is not being used .

(I] Tips
•
For safety reaso ns, t he stored speed is deleted when the igni tion

• T he Elect ronic Stabilization Program (ESP) and the Ant i- Slip Regu

is sw itched on . If the ES P and t he Anti -S li p Reg ula tio n (ASR) has been
deactivated and you then switch on the Adaptive Cruise Control, the
E S P fu nction will also be a ctivated au toma tically.
• Damage cause d by accidents and some minor coll is ions can affect

& WARNING
If ACC initiates a braking maneuver, the brake pedal will be
retracted . Interference with the brake pedal can prevent ACC from
slowing the vehicle down and cause a crash and serious personal
injury .
• Never put anything
in the driver's footwell or let anything fall
into it. An object in the driver 's footwell can interfere with the
pedals and prevent the accelerator from being used to override
ACC or prevent ACC from being switched off when the brake pedal
is depressed and also prevent the vehicle from being slowed down
or stopped.
• Only use floor mats that keep the area around the pedals free
and that can be securely fastened to the footwell.
• Never drive with your foot underneath the brake pedal.
• Always read and heed the information and WARNINGS~
& in
" Description " on
page 134.
& WARNING
• Never rely on the distance control feature of ACC alone to
prevent rear-end collisions. Always be prepared to brake and take
evasive action to avoid collisions and other accident situations.
• Never allow the closing speed between you and other vehicles
to be so high that the Adaptive Cruise Control may not be able to slow your vehicle safely. If closing speed is too high , you must
apply the brakes yourself to reduce the risk of a rear-end crash.
