WARNING
If you open the bonnet while the engine is
overheating or while there is a fire in the
engine compartment, you could come into
contact with hot gases or other leaking ser-
vice products. There is a danger of injury.
Allow an overheating engine to cool down
before opening the bonnet. If there is a fire in
the engine compartment, leave the bonnet
closed and notify the fire brigade.
The coolant temperature gauge is in the instru-
ment cluster on the right-hand side (

Under normal operating conditions and with the
specified coolant level, the coolant temperature
may rise to 120 †.
At high outside temperatures and when driving
in mountainous terrain, the coolant temperature
