and faster than 5 mph (5 km/h) . .,._
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
• Press the brake pedal to stop the vehicle .
• Apply the parking brake firmly
r=,> page 109,
fig. 123 @.
• Move the selector lever to P.
.. Turn the engine off~_& .
.. When on inclines or declines, turn the steer
ing wheel so that the vehicle will roll into
the curb if it begins to
move.
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.
Q) 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 th@ 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
vehicle must be standing in uphill driving di rection.
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 begin to
move your
vehicle.
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
parking brake.
- Should the engine stall, depress the
brake pedal immediately or engage the
parking brake.
- In order to prevent the vehicle from roll
ing back unintentionally when starting in
stop-and-go traffic, keep the brake pedal
depressed for a few seconds before driv
ing off .
- When you leave the vehicle - even if only
briefly -, sw itch off the ignition and
make sure to remove the ignition key . Al
so engage the
park ing br ake to prevent
your vehicle from rolling u nintentionally.
Th is parti cularly applies if chi ldren are
left in the vehicle - danger of accident!

the type of display in your vehicle.
A 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 veh icles .
- For safety reasons, 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
p laning) - risk of accident.
- Turn off the cruise control temporarily
when en ter ing turn lanes, highway exit
lanes or in construction zones .
- Please note that inadvertently "resting"
your foot on the accelerator pedal causes
the cruise control not to brake. This is because the cruise control is overridden
by the driver's acceleration.
- Never use the cruise control when driving
off-road o r on unpaved roads. The cruise
control 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 .
(D Tips
The cruise control cannot maintain a con
stant speed when driving downhill. The ve
hicle will accelerate under its own weight .
Downshift to a lower gear or use the
brakes to slow down.

Introduction
The automatic transmission is controlled elec
tronically. The transmission upshifts or down
shifts automatically depend ing on which drive
program is selected. The power is transferred
by a torque converter .
When a

transmission selects the most econom ica l
driving mode. It w ill then change up early and
delay the downshifts to g ive better fuel econ

T he transmission switches to a sporty mode
after a k ick-down or when the driver uses a
spo rty driving sty le characterized by quick ac
celerator pedal movements, heavy accelera
tion, frequent changes in speed and traveling
at the maximum speed.
If desired, the driver can a lso select the gears
