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
#

Limited braking effect on salt-treated roads:
Due to salt build-up on the brake discs 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
