POSSIBLE CAUSES
In the diesel version, this is necessarily a
fault. Smoke may be caused by particle
filter regeneration.
This is not necessarily a fault. The smoke
may come from the heater.
If this happens, the smoke will gradually
disappear once the passenger compart-
ment temperature has reached the ap-
propriate level.
Short-circuit or cooling system leak.
The level is too low.
Loss of oil pressure.
WHAT TO DO
Please refer to the information on "Special
features of diesel versions" in Section 2.
Stop, switch off the ignition, stand away
from the vehicle and contact an approved
dealer.
Top up the engine oil level (refer to the in-
formation on "Engine oil level: topping up,
filling" in Section 4).
Stop the vehicle and contact an approved
Dealer.
