STARTING AND DRIVING
Petrol particle filter
Petrol cars are fitted with particle filters for more
efficient emission control.
Particles in the exhaust gases are collected in
the petrol particle filter during normal driving. In
normal driving conditions, passive regeneration
takes place, which leads to the particles being
oxidised and burned away. The filter is emptied in
this way.
If the car is driven at low speed or with repeated
cold starts in low outside temperature, active
regeneration may be necessary. Regeneration of
the particulate filter is automatic and normally
takes 10-20 minutes. There may be a smell of
burning during regeneration.
Use the parking heater in cold weather - the
engine then reaches normal operating tempera-
ture more quickly.
When driving short distances at low
speeds in a petrol car
The capacity of the emissions system is affected
by how the car is driven. It is important to drive
varying distances at different speeds to achieve
optimal performance.
Driving short distances at low speeds (or in cold
climates) frequently, where the engine does not
reach normal operating temperature, can lead to
problems that can eventually cause a malfunction
and trigger a warning message. If the vehicle is
mostly driven in city traffic, it is important to regu-
436
larly drive at higher speeds to allow the emissions
system to regenerate.
The car should be driven on A-roads at
•
speeds in excess of 60 km/h (38 mph) for at
least 20 minutes between each refuelling.

Overheating in the engine and drive
system
Under certain conditions, e.g. hard driving in hilly
terrain and hot climate, there is a risk that the
engine and drive system may overheat – in par-
ticular with a heavy load.
In the event of overheating, the engine's
•
power may be limited temporarily.
Remove any auxiliary lamps from in front of
•
the grille when driving in hot climates.
If the temperature in the engine's cooling
•
system becomes too high then a warning
symbol is illuminated and the driver display
shows the message Engine temperature
High temperature Stop safely
car in a safe way and allow the engine to run
at idling speed for several minutes and cool
down.
If the message Engine temperature High
•
temperature Turn off engine
coolant Level low, turn off engine
shown, stop the car and switch off the
engine.
In the event of overheating in the gearbox, an
•
alternative gear shift program will be
selected. In addition, a built-in protection
function is activated that, amongst other
things, illuminates a warning symbol and the
driver display shows the message
Transmission warm Reduce speed to
lower temperature or Transmission hot
