A WARNING
If a drive range is engaged with the vehicle
stationary and the engine running, you must
in no instance accelerate care lessly. Other

(D Tips
- If the parking brake is app lied with the igni

windows). There is the risk of an acc ident.
- When the vehicle is loc ked, no one - particu

When stopp ing at a t raffic sig na l or s topping in
c ity traff ic on vehicles with an automat ic t rans
mission, the pa rking brake can be applied . The
vehicle does not have to be held with the foot brake. The parking brake eliminates the tendency
to c reep w ith a dr ive range engaged . As soon as
you drive off as usual, the parking brake is re
leased automat ica lly and the vehicle starts to

@ Tips
For safety reasons, the park ing brake is re

that you are developing enough driving force at
the wheels by depressing the accelerator .
Depending on the weight of the r ig (vehi cle and
tra iler) and the severity of the incline, you may
ro ll backwards as you start . You can prevent roll
ing backwards by holding the parking brake
switch pulled out and accelerating -just as you
wou ld when starting on a hill with a conventiona l
h and brake .
Emergency braking
In the event that the conven tional brake system
fails or locks .
~ In an emergency, pull the sw itch and cont inue
to pull it to slow your veh icle down with the
parking b rake.
~ As soon as you release the switch or accelerate,
the b raking process stops .
If you pull the sw itch and hold it above a speed of
about 5 mph (8 km/h) , the eme rgency braking
function is in it iated . The vehicle is braked at all
four wheels by activating the hydraulic brake sys

sounds w hen the sw itch is p ulled. As soon as t he
sw itch is rele ased, or the acce le ra to r p edal is de
p ressed, eme rgency bra king stops.
A WARNING
Emergency bra king should only be use d in an
emergency, w hen the normal foot brake has
fai led or the bra ke pedal is obstructed . Using
the par king b rake to perfo rm emergency
brak ing will slow your vehicle down as if you
had made a full bra ke ap plication . The laws of
physics cannot be suspended even wi th ESC

A WARNING
--
-Always pay attention to the traffic around
you when the cruise control is in operation .
You are always respons ible for your speed
a nd the distance between your veh icle and
o ther veh icles.

Driving
-For reasons of safety, cruise control should
not be used in the city, in stop-and-go traf
fic, on twisting roads and when road condi
tions are poor (such as ice, fog, gravel, heavy rain and hydroplaning) -you could
have an accident.
- Switch the cruise control off temporarily when driving in turning lanes, highway exits
or in construction zones.
- Please note that unconsciously "resting"
your foot on the accelerator pedal causes cruise control not to brake . This is due to
the control system being overridden by the
driver's acceleration.
- Never use the cruise control when driving
off-road or on unpaved roads. The cruise
control is intended for use only when the ve
hicle is being operated on paved roads, and
is not suitable for use off-road or on un
paved roads.
- If a brake system malfunction such as over
heating occurs when the cruise control sys
tem is switched on, the braking function in
the system may be switched off. The other
cruise control functions remain active as
long as the indicator light
tii;(O~i4 (US mod
el)/lil (Canadian model) is on .
{D) Tips
The brake lights illuminate as soon as the
brakes apply automatically.
Changing speed
.,. To increase/decrease the speed in increments,
tap the lever in the
010 direction ¢ page 95,
fig. 108 .
.,. To increase/decrease the speed quickly, hold
the lever in the
010 direction until the de
sired speed is displayed.
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 re
sume as soon as you let off of the accelerator
pedal.
If, however, you exceed your saved speed by
S mph
(10 km/h) for longer than 5 minutes, the
96
cruise control will be turned off temporarily. The
green symbol in the display turns white, the
saved speed is retained.
Pre-selecting speed
You can pre-select your desired speed while the
vehicle is not moving.
.,. Turn on the ignition.
.,. Pull lever into position
(D ¢page 95, fig. 108.
.,. Press the lever in the 0 or 0 direction to in-
crease or decrease your speed.
.,. Let go of the lever to save that speed .
This function makes it possible, for example, to
save the speed you want before driving on the
highway. Once on the highway, activate the
cruise control by pulling the lever toward

Switching off
Temporary deactivation
.,. Step on the brake pedal, or
.,. Press the lever into position @ (not clicked into

page 95, fig . 108, or
.,. Drive for longer than 5 minutes at more than
5 mph (10 km/h) above the stored speed.
Switching off completely
.,. Press lever into position @ (clicked into place),
or
.,. Switch the ignition off .
The speed you saved will be retained if the cruise control has been switched off temporarily . To re
sume the saved speed , let up on the brake and
