& WARNING
Reduced visibility is dangerous and can cause accidents.
• For safe driving it is very important that all windows be free of
ice, snow and condensation.
• Completely familiarize yourself with the proper use and func­
tion of the heating and ventilation system and especially how to
defog and defrost the windows.
• Never use the windshield wiper/washer system in freezing
weather until you have warmed the windshield first, using the
heating and ventilation sy stem. The washer solution may freeze
on the windshield and reduce visibility.

Parking
To p revent a parked vehicle from rolling away, there are
a fe w things you should do.
When you park your vehicle , do the following
- Stop t he veh icle us ing the bra ke pedal.
- Pull the switch to apply t he electromechanica l parking
brake .
- Move th e se lector lev er in to the
P position ~& .
- Switch off the e ngine and remove the ignition key from
the ignition lock.
When you park your vehicle on hills, do the
following
- Stop the veh icle us ing the bra ke pedal.
- Pull the switch to apply t he e lectromechanica l parking
brake .
- I f you a re parkin g h eaded
downhill , turn the front w heels
toward th e curb .
- I f you are parking headed
uphill , turn t he fro nt wh eels
away from t he curb.
- M ove the selector lever into the
P position.
- Switch off the e ngine and remove the ign it ion key from
the ignition lock.
& WARNING
Thi s is how you can reduce the risk of injury when lea ving your
vehicle.
& W ARNING (continued )
• Never park the vehicle where it can come in contact with dry
grass , spilled fuel or any other flammable material s.
• When parking on hills, always turn the wheel s so that the front
wheel s 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 difficult
fo r rescu ers to acce ss the passenger compartment in the event of
an emergency. Danger to life!
• Never leave children unsuperv ised in the vehicle. Ch ildren
could relea se the parking brake or move the gear shift lever out of
gear. The vehicle could start to roll away and cau se an accident .
• No matter what the season i s, the temperature
in a parked
v ehicle can reach dangero us le vels .
0 Note
• Please exercise care when you pa rk your veh icle in parking areas
w ith park ing barriers o r cur bs. Parking barriers and curbs vary in
he ight and could damage your bumpe r and related components as
the front of your vehicle moves over a ba rrier or curb that is too high,
as you park or as you back out of a pa rking spot. In order to be sure
that no such damage can occur, yo u may wish to stop short of having
t he fro nt t ires of you r car touch t he p arking bar rie r or curb.
• Please a lso exerc ise except iona l care when you drive up or down
steep ramps or drive over curbs or o ther obstacles, for which the
vehicle is not des igned, because components of the vehicle close to
t he ground, s uch as bumpe r covers, spoilers and suspension and
exhaust system components, may become damaged. •

On the road ---------------~:..:.....__
Starting off with a trailer
To prevent rolling back unintentionally on an incline, do
the following:
- Keep the switch pulled and depress the accelerator. The
parking brake stays applied and p reve nts the vehicle from
rolling backward .
- You can release t he switch once you are sure t hat you are
deve loping enough forward momentum at the whee ls as
you depress the acce lerator .
Depending on the we ight of the rig (vehicle and trailer) and the
severity of the incline, yo u may roll backwards as you start. You can
prevent rol ling backwards by holding the park ing bra ke sw itch pulled
out and accelerating -just as you wou ld when starting on a hill with a
conventional hand brake .•
Emergency braking
In the event that the conventional brake system fails or
locks.
- P ull the swi tch and cont inue to pull it to s low your veh icle
with the parking brake in an emergency .
- As soon as you re lease the sw itc h or accelerate, the
braking process stops .
If you pull the switch and hold it above a speed of abou t 5 mp h (8
km/h), the emergency braking function is init iated. The vehicle is
bra ked at all fou r wheels by activat ing the hydraulic b rake system.
Brake performance is s imilar to making an emergency stop~,&.
So that emergency braking is not activated by mistake, an audible
warning tone (buzzer) sounds when the switch is pulled . As soon as
Controls and equip ­
ment Safety first
the switch is released, or the accelerator pedal is depressed, emer­
gency braking s tops.
& WARNING
Em erg ency braking should only be u sed in an emergen cy, wh en
the no rmal foot brake ha s failed o r the brake pedal i s obstructed.
U sing the park ing b rake to perform emerg ency braking will slow
your vehicl e as if you had made a full brake application . The laws
of phy sic s c annot be su spen ded even wi th ESP and it s ass ociated
c omponents (ABS, ASR , ED S). In corn ers and when r oad or
weather condit ion s are bad , a full brake application can cause the
ve hicl e to sk id or the rear end to br eak away- r isking an accid ent .•

The display => fig. 137 will show the set speed. The d isp lay may vary

T he speed is kept constant via an eng ine output adjustment or act ive
brake intervention.
& WARNING
• Alway s pay attention to traffic even when the cruise control i s
switched on. You are always responsible for your speed and the
di stan ce between your vehicle and other vehicles.
• For safety r easons , the cruise control should not be used in the
city, in stop-and-go traffic , on twisting roads and when road
conditions are poor ( such as ice , fog, gravel, heavy rain and hydro­
planing ) -risk of accident .
• Turn off the cruise control temporarily when enter ing turn
lanes , highway exit lane s or in construction zone s.

__________________________________________ A_ d_ a_,_ p_t _iv _ e_C_ r_u _i _ s _e _C_ o_n_ t_ r_ o_ l __ _
& WARNING (continued)
slow your veh icle safely. If clos ing speed is too high , you must
apply the brake s your self to reduc e the ri sk of a rear-end cra sh .
• Never re st you r foot on the accelerator pedal , especially when
the Adaptive Cruise Control is being used. Pressure on the acceler­
ato r will override the ACC braking function and prevent the brakes
from being applied when ACC detects a situation when the brakes
must be applied.
• Never use Adaptive Cruise Control when you cannot drive safely
at a steady speed, including on city st reets , 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 ris k of hydroplaning ).
• The radar sensor's
vision can be reduc ed 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
sen sors cannot ac curately detect vehicles moving ahead of you in
traffic .
• Alway s turn off Adaptive Crui se Control when entering turn
lanes , exit lanes and construction zones o r in similar situat ions
because the vehicle will automatically ac celerate to the stored
speed when the road ahead is clear .
• To prevent unintended operation , always switch ACC off when
it is not being used .
[ i] Tips
• For safety reasons, the stored speed is deleted when the ignition
i s turned o ff.
• When Adapt ive Cruise Control is switched on, the Electronic Stabi­
li zation Program ( ESP) is also automa tica lly activ ated.
• Damage caused by accidents and some minor collisions can affect
th e rad ar senso r se ttings and ca use the syste m to m alfunction o r
switch off completely.
