depress the accelerator pedal. For exam-
ple, if you accelerate briefly to overtake,
cruise control adjusts the vehicle's speed
to the last speed stored after you have fin-
ished overtaking.
i Vehicles with AUTOTRONIC*:
When you decelerate the vehicle using the
cruise control lever, AUTOTRONIC changes
down if deceleration is insufficient.
Making fine adjustments in
1 km/hincrements X
Briefly press the cruise control lever up
1 for a higher speed or down 4for a
lower speed.

cator lamp 2in the cruise control lever
lights up.
Cruise control is automatically deactivated if,
for example:
R aquaplaning is detected
R you press the clutch pedal for more than
four seconds on vehicles with a manual
transmission
R you move the selector lever to Nwhile driv-
ing in vehicles with AUTOTRONIC*
i The last speed stored is cleared when you
switch off the engine. Speedtronic*
Speedtronic is used to make sure that you do
not exceed a stored speed. You must select
a low gear in good time on long and steep
downhill gradients, especially if the vehicle is
laden or towing a trailer. By doing so you will
make use of the braking effect of the engine,
which relieves the load on the brake system
and prevents the brakes from overheating
and wearing too quickly. G
Risk of accident
Never depress the brake pedal continu-
ously while the vehicle is in motion, e.g.
never cause the brakes to rub by applying
constant slight pedal pressure. This causes
the brake system to overheat, increases
the braking distance and can lead to the
brakes failing completely. G
Risk of accident
Do not change down for additional engine
braking on a slippery road surface. This
could cause the drive wheels to lose their
grip and the vehicle could skid. Controls

Speedtronic is only an aid designed to
assist driving. You are responsible for the
vehicle's speed and for braking in good
time.
i The speed indicated in the speedometer
may differ slightly from the limit speed

Risk of accident
If there is a change of drivers, advise the
new driver of the limit speed stored.
Only use Speedtronic when you do not have
to accelerate suddenly to a speed higher
than the stored limit speed allows. You
could, otherwise, cause an accident.
You can only exceed the limit speed stored

R using the cruise control lever
R by depressing the accelerator pedal

Risk of accident
Parktronic is only an aid and may not detect
all obstacles. It is not a substitute for atten-
tive driving.
You are always responsible for safety and
must continue to pay attention to your
immediate surroundings when parking and
manoeuvring. You could, otherwise, endan-
ger yourself and others. G
Risk of injury
Make sure that no persons or animals are
in the manoeuvring range. Otherwise, they
could be injured.
Parktronic is an electronic parking aid using
ultrasound. It indicates visually and audibly
the distance between your vehicle and an
object.
Parktronic is automatically activated when
you switch on the ignition and release the
handbrake.
Parktronic is deactivated at speeds above
18 km/h. It is reactivated at lower speeds.
Parktronic monitors the area around your
vehicle using six sensors in the front bumper
and four sensors in the rear bumper. Controls
