Checking the tyre pressure
SIMPLY features pneumatic tyres as standard� In order to keep rolling resistance
to an absolute minimum, you should check the tyre pressure at regular intervals�
The tyres are standardly equipped with automobile valves, so you can check the
pressure by using the tyre gauge at your local petrol station� The required filling
pressure is printed on the tyres and is also specified in the “technical data” sec-
tion of these instructions� To check the tyre pressure, please proceed as follows:
Apply the parking brake (see section

Unscrew the valve cap from the valve by turning it anti-clockwise�
Press the tyre gauge nozzle firmly onto the valve�
Correct the tyre pressure to the specified value�
Remove the tyre gauge nozzle from the valve�
Screw the valve cap onto the thread of the valve (clockwise)�
Repeat the operation until you have checked all tyres�
If necessary, release the parking brake (see section

Important:
Depending on the version, the front and rear wheels require different
tyre pressures�

The Bowden cables of the parking brakes are routed through an adjusting
bolt before the brake backing plates, which allows an adjustment of the
braking power�
By turning this bolt anti-clockwise, the brake cable is brought under greater
tension, pre-tensioning the brake� The adjusting bolt is secured by a nut�
Before adjusting the brake, release the securing nut by turning it to the left
(depending on the version, a size

spanner may be required)�
