Switching the ignition on/off
If you would like to switch the ignition on with­
out starting the engine, follow these steps:
• Press the
!START E NGINE STOPI button with­
out pressing the clutch pedal (for manual
transmissions) or the brake pedal (for automat­
ic transmissions) .
• To switch the ignition off, press the button
again.
Driving
If the engine should not start immediately, the
starting process is automatically stopped after a
short time. Repeat starting procedure.
When starting the engine, major elect rical loads
are switched off temporarily .
After a cold engine is started, there may be a
brief period of increased noise because oil pres­
sure must fi rst bui ld up in the hydraulic valve ad­
justers. This is normal and not a cause for con ­
cern.
.&_ WARNING
-~ ·
-Never allow the engine to run in confined
spaces - danger of asphyxiation.
- Never turn off the engine until the vehicle
has come to a complete stop.
- Always take the key with you whenever you
leave your vehicle. Otherwise, the engine
could be started or electrical equipment
such as the power windows could be operat­
ed . This can lead to serious injury.
- Never leave children or persons requiring as­
sistance unattended in the vehicle. The
doors can be locked using the remote trans­
mitter, preventing people from escaping
from the vehicle on the ir own in the event of
an emergency. Depending on the time of
year, people inside the vehicle can be ex­
posed to very high or very low tempera­
tures.
CD Note
- Avo id high engine rpm, full throttle and
heavy eng ine loads until the engine has
reached operating temperature -otherwise
you risk engine damage.
@ For the sake of the environment
Do not let the engine run wh ile parked to
warm up. Begin driving immediately. This re­
duces unnecessary emissions .
@ Tips
-After starting a cold engine, there may be a
brief period of increased noise because the

oil pressure must first build up in the hy ­
draulic va lve adjusters. This is normal and
not a cause for concern .

ter a certa in period o f time . P lease note that
electr ica l equipment suc h as exterior lights
will switch off as well when that happens.

the instrument cluste r illuminate.
.. W ith the ignition switched on, step o n the
brake peda l or the accelerator pedal and press
the switch @ at the same time to release the
pa rking brake . The i ndicator lig hts in the sw itch
and . (USA models) . (Canada models) in
th e inst rument cluster go out .
Your vehicle is equipped with an electromechani­
ca l park ing brake . T he pa rking brake is designed
to preve nt the vehicle from ro ll in g u nintent ional­
ly and replaces the hand brake .
In add ition to the normal functions of a tradition­
al hand brake, the electromechanical parki ng
brake p rov ides va rious conve nience and saf ety
funct ions.
When starting from rest
- The integral start ing ass ist helps you when
driving by automatically releasing the park ing
brake
¢ page 78, Starting from rest .
-When starting o n inclines, the starting assist
prevents the vehicle from unintentionally ro ll­
ing back . The b rak ing force of the parking brake
i s not re leased until s ufficie nt driving force has
been built up at t he whee ls.
Emergency brake function
An emergency brake ensures that the vehicle can
be s lowed down even if t he
normal brakes fail
¢ page 79, Emergency braking .
A WARNING
If a gear or a drive ra nge (au tomati c tr an smis­
s ion) is engaged w ith the vehi cle sta tion ary
a nd the e ng in e runn ing, you m ust in no in­
stance ac ce lerate or re lease the cl utch* care ­
l essly. Otherwise the vehicle will start to
move immediately - risk of an accident.
(1) Tips
- If the p arking br ake is app lied wi th the ign i­
tion sw itche d off, the ind icator lights in the
swit ch and -(USA mo dels)/ . (Cana­
da mode ls) i n the instrument cluster will go
out after a certain per iod of t i me.

Driving
-Oc ca siona l noises when the parking brake is
applied and released are normal and are not
a cause for conce rn.
- When the vehicle is parked, the parking
brake goes thro ugh a se lf-test cycle at regu­
l ar inte rvals . Any associated noises are nor­
mal.
Parking
.,. Press the brake pedal to stop the vehicle .
.,. Pull the switch@¢
page 77, fig. 81 to set the
parking b rake.
.,. Automat ic transm iss ion: Move the se lector lev-
er to P.
.. Turn the eng ine off ¢,&. .
.. Manua l transmission: Shift in to 1st gea r.
.. When on inclines or declines, tu rn the steering
whee l so that the vehicle w ill roll into the curb
if it beg ins to move.
A WARNING
- When you leave your veh icle -even if only
br iefly -always remove the ignition key . This
applies part icu larly when children remain in
t h e ve hicl e. Otherwise the childre n could
s tar t the engine, release the p arking br ake
or opera te e lectr ica l equi pment (e.g . power
win dows) . There is the ris k of an acci den t.
- When the vehicle is lo cked, no one -particu­
larly not children should rema in in the vehi ­
cl e. Locked doors make it more difficult for
emergency wor kers to get into the vehicle -
putt ing lives at risk.

Starting and automatically releasing the
park ing brake
.. When you sta rt to drive as usual, the parking
bra ke is automatically released and yo ur vehicle
beg ins to move.
When stop ping at a traffic signal or stopping in
c ity t raffic on vehicles with an a utomat ic t rans ­
mission, the parking brake can be app lied. The
vehicle does not have to be he ld with the foot­
brake. The pa rking brake eliminates the tendency
to c reep with a d rive ra nge engaged. As soon as
yo u drive off as usua l, the park ing b rake is re­
l eased a utomat ica lly and the vehi cle starts to
m ove .
Starting on slopes
When sta rting on inclines, the starting assist pre ­
ven ts the vehicle from unintentionally ro lling
bac k. The braking force of the parking b rake is
n ot released until suff icient dr iving force has
been built up at the wheels.
(D Tips
For safety reasons, the pa rking bra ke is re­
l eased a utoma tically on ly w hen t he d river's
s a fety be lt is en gaged in t he b uckle.
Starting off with a trailer
To prevent rolling back unin tentionally on an in­
cline, do the f ollowing:
.. Keep the sw itch @¢ page 77, fig . 81 pulled
and dep ress the accelera to r. T he pa rking brake
s t ays app lied and p revents the veh icle from
roll ing ba ckw ard .
.. Yo u can re lease the swi tch @ once you are s ure
that you are deve loping enough d riving force at
the whee ls by depressing the accelerato r.
Depend ing on the weight of the rig (vehi cle an d
t ra ile r) and the seve rity of the incline, yo u may
r o ll backwards as yo u start. You can p revent roll­
i ng backwards by holding the parking brake
switch @pulled o ut and acce lerating -just as
you would when starting on a hill wi th a conven­
tiona l hand b rake .

i? co
-For reas ons of safety, cruise contro l should
not be used in the city, in stop-and-go traf­
fic, on twisting roads and when road condi­
t ions are poor (such as ice, fog, gravel,
heavy rain and hydrop laning) -risk of acci­
dent .
- Turn off the cruise control temporari ly when
enter ing turn lanes, highway exit lanes or in
construction zones.
- Please note that inadvertent ly "rest ing"
yo ur foot on the accelerator peda l causes
the cruise control not to brake. This is be­
c a use the cruise co ntro l is ove rri dden by the
dr iver's acceleration .
-If a brake system malfunc tion such as ove r­
he ating occu rs when the c ruise control sys­
tem is switche d on, the braking func tion in
the system may be switche d off . The other
c ruise control functions remain active as
long as the indicator light

(D Tips
- Vehicles with manua l t ransmission: You can
attain the set speed only if the gear t hat is
currently engaged will allow it, or if it does
not tax t he engine and allows it to run
smooth ly. Therefore shift i nto a higher or
l ower gear in a time ly ma nner.
- The brake lights illuminate as soon as the
brakes app ly automatically .
