110 On the road
The parking brake warning light. (USA)/ .
(CON) illuminates when the parking brake is
set and you switch on the ignition.
A WARNING
-
Always release the parking brake com
pletely. A partially engaged brake will
overheat the rear brakes, reduce their ef
fectiveness and cause excessive wear. This could lead to brake failure and an accident .
(D Note
Only after the vehicle has come to com
plete stop, should you firmly set the park
ing brake and
move the selector lever into
"P".
Parking
When you park your vehicle, do the
following
• Stop the vehicle using the brake pedal.
• Apply the parking brake firmly.
• Move the selector lever into the P position
c:>A .
• Switch off the engine and remove the igni-
t ion key from the ignition lock.
When you park your vehicle on hills, do
the following
• Stop the vehicle using the brake pedal.
• Apply the parking brake firmly.
• If you are parking headed
downhill, turn
the front wheels
toward the curb.
• If you are parking headed uphill, turn the
front wheels
away from the curb.
• Move the selector lever into the
P position.
• Switch off the engine and remove the igni
tion key from the ignition lock.
A WARNING
This is how you can reduce the risk of in
jury when leaving your vehicle.
- Never park the vehicle where it can come
in contact with dry grass, spilled fuel or
any other flammable materials. -
When parking on hills, always turn the
wheels so that the front wheels will first roll into the curb, if the vehicle should
start to roll.
- Never allow anyone - especially small
children - to remain in the vehicle when
it is locked. Locked doors make it more
difficult for rescuers to access the pas
senger compartment in the event of an
emergency. Danger to life!
- Never leave children unsupervised in the
vehicle. Children could release the park
ing brake or
move the gearshift lever out
of gear. The vehicle could start to roll
away and cause an accident.
- No matter what the season is, the tem
perature in a parked vehicle can reach
dangerous levels.
(D Note
- Please exercise care when you park your
vehicle in parking areas with parking bar riers or curbs. Parking barriers and curbs
vary in height and could damage your
bumper and related components as the
front of your vehicle moves
over a barrier
or curb that is too high, as you park or as
you back out of a parking spot. In order
to be sure that no such damage can oc
cur, you may wish to stop short of having
the front tires of your car touch the park
ing barrier or curb.
- Please also exercise exceptional care
when you drive up or down steep ramps
or drive over curbs or other obstacles, for
which the vehicle is not designed, be
cause components of the vehicle close to
the ground, such as bumper covers, spoilers and suspension and exhaust sys
tem components, may become dam
aged.
Starting on hills
Hill Hold makes it easier to start on hills.
The system is activated when the brake pedal is depressed
for a few seconds. For this, the ll-
vehicle must be standing in uphill driving direction.
After releasing the brake pedal , the brake
power is held for a
brief moment to prevent
the vehicle from rolling back when starting. At
this time, you can easily beg in to move your
veh icle.
A WARNING
- If you did not begin moving immediately
after releasing the brake pedal, under
certain circumstances, the vehicle would
begin to roll backward . Depress the
brake pedal immediately or engage the
park ing brake.
- Should the engine stall, depress the
brake pedal immediately or engage the
par king brake.
- In order to prevent the vehicle from ro ll
ing back un intentionally when sta rting in
stop-and-go traffic, keep the brake pedal depressed for a few seconds before d riv
ing off.
- When you leave the vehicle -even if only
briefly - , switch off the ignition and
make sure to remove the ignition key . Al
so engage the
p a rking b rake to prevent
your vehicle from rolling unintentionally. Th is particu larly applies if ch ildren are
left in the veh icle -danger of acc ident!

_& WARNING
- Always pay attention to traffic even when
the cruise control is switched on. You are
always responsible for your speed and
the distance between your veh icle and
other vehicles .
- For safety reasons, the cruise contro l
should not be used in the city , in stop
and -go traffic, on twisting roads and
when road condit ions are poor (such as
ice, fog , gravel , heavy rain and hydro
p lan ing) -risk of accident.
- Turn off the cruise control temporarily
when enter ing turn lanes, highway exit
lanes or in construction zones.
- Please note that inadvertently "resting"
your foo t on the accelerator pedal causes
the cruise contro l not to bra ke. This is
because the c ruise control is overridden
by the driver's acceleration.
- Never use the cruise control whe n driving
off -road or on unpaved roads. The c ruise
contro l is intended for use only when the
vehicle is being operated on paved roads,
and is not suitable for use off-road or on
unpaved roads.

A WARNING
- Never rely on the distance control fea
ture of ACC alone to prevent rear-end col
lisions . Always be prepared to brake and
take evasive action to avoid collisions and other acc ident situations.
- Never allow the clos ing speed between
yo u and other vehicles to be so h igh that
the adaptive c ruise control may not be
able to slow your vehi cle safe ly. If clos
ing speed is too high, you m ust app ly the
brakes yourself to reduce the risk of a

-
Following other vehicles too closely in

- Following other vehicles too closely, par
ticu larly at higher speeds increases the
risk of coll is ions and serious personal in

available to bring your vehicle to a safe
stop and makes it even more necessary
to pay close attention to traffic .
- Always select a speed and distance to
traffic ahead that is safe and appropriate
under the prevailing traff ic, road, weath
