Do not depress the brake pedal and the
#
accelerator pedal at the same time
while driving.
* NOTE Causing wear to the brake linings

#
vehicle is stationary. Pull away immedi‐
ately.
Avoid high engine speeds and driving at
#
full throttle until the engine has reached
its operating temperature.
* NOTE Damage to the catalytic converter

lytic converter.
Only depress the accelerator pedal

slightly.
Have the cause rectified immediately at
#
a qualified specialist workshop.
Driving and parking 155
Limited braking effect on salt-treated roads:
due to salt build-up on the brake disks and
R
brakepads, the braking distance can increase
considerably or result in braking only on one
side
maintain a much greater safe distance to the
R
vehicle in front
To prevent salt build-up:
brake occasionally while paying attention to
R
the traffic conditions
carefully depress the brake pedal at the end
R
of the journey and when starting the next
journey
ECO start/stop function
Operation of the ECO start/stop function
The engine is automatically switched off if the
following conditions are met:
vehicles with manual transmission: you
R
