i The last speed stored is cleared when you
switch off the engine. Speedtronic*
Speedtronic brakes automatically so that you
do not exceed the set speed. On long and
steep downhill gradients, especially if the
vehicle is laden or towing a trailer, you must
shift to a lower gear in good time or select
shift range 1,2 or 3in vehicles with automatic
transmission*. In this way 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. If you need additional
braking, depress the brake pedal repeatedly
rather than continuously. 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. Thi s
could cause the drive wheels to lose thei r
grip and the vehicle could skid. Controls

Permanent Speedtronic (vehicles with
a
12-button luxury multi-function steer-
ing wheel*) i
Permanent Speedtronic is only availabl e
for certain countries.
You can use the on-board computer to limi t
the speed permanently to a value between
160 km/h (e.g. for driving with winter tyres )
and the maximum speed.
Shortly before the stored speed is reached, it
is displayed in the multi-function display.
You cannot exceed the stored limit speed,
even if you depress the accelerator pedal
beyond the pressure point (kickdown).

tings menu and select with #.

X Press #to save the entry . Hill start assis
t
Hill start assist helps you when pulling away
on uphill gradients. It causes the vehicle to be
held for a short time after you have removed
your foot from the brake pedal. This allow s
you enough time to move your foot from th e
brake pedal to the accelerator pedal and pull
away without the vehicle rolling backwards. G
Risk of accident
Never leave the vehicle if it is being braked
by the hill start assist function. After around
one second the hill start assist function will
no longer brake your vehicle and it can rol l
away.

Optimum operation of Thermotronic is only

R The selected temperature
R The outside temperature
R The intensity of the sunlight
i Ventilate the vehicle for a brief period
during warm weather, e.g. using the sum-
mer opening feature (Y page 111). This helps you to achieve the desired interior
temperature more quickly.
The integrated filter filters out most particles
of dust and completely filters out pollen.
i A clogged filter reduces the amount of ai r
supplied to the vehicle interior. For this rea-
son, you should always observe the interval
for replacing the filter, which is specified in
the Service Booklet. As it depends on envi-

than stated in the Service Booklet. G
