STARTING AND DRIVING
430heating. This includes: altering fuel injec- tion settings or components, alteringemission system components or locationor removing components, and/or repeateduse of leaded fuel.
NOTE
Unleaded fuel is required for vehicles with three-way catalytic converters.
Heated oxygen sensorsThe heated oxygen sensors monitor the oxy- gen content of the exhaust gases. Readingsare fed into a control module that continuouslymonitors engine functions and controls fuelinjection. The ratio of fuel to air into the engineis continuously adjusted for efficient combus-tion to help reduce harmful emissions.

Overheating of engine and transmission
In certain driving conditions, such as driving in mountainous areas or hot weather, there isa risk of the engine or transmission overheat-ing, especially when carrying heavy loads.
Engine power may be temporarily limited.
Remove any auxiliary lights mounted in front of the grille when driving in hotweather.
If the temperature in the engine's coolingsystem becomes too high, a warning sym-bol will appear in the instrument panel along with the message
Engine
temperature High temperature Stop
safely. Pull over to a safe location and let
the engine idle for a few minutes to cool down.
If the message
Engine temperature
High temperature Turn off engine orEngine coolant Level low, turn off
engine is displayed, stop the vehicle and
turn off the engine.
If the transmission begins to overheat, an alternative gear shifting program will beselected. An integrated protective functionwill also be activated, the warning symbolwill illuminate and the message
Transmission warm Reduce speed to
lower temperature or Transmission hot
Stop safely, wait for cooling will be dis- played in the instrument panel. Follow the recommendations given by reducingspeed or stopping the vehicle safely andletting the engine idle for a few minutes tolet the transmission cool.
If the vehicle begins to overheat, the airconditioning may be temporarily switchedoff.
After a prolonged period of driving indemanding conditions, do not turn off theengine immediately after stopping.
NOTE
It is normal for the engine's cooling fan to operate for a short time after the engine isswitched off.
Symbols in the instrument panel
Symbol Meaning
High engine temperature. Follow the recommendations provided.
Low coolant level. Follow the recommendations provided.
Transmission hot/overheated/ cooling. Follow the recommen-dations provided.

CAUTION
Do not ingest the contents. May cause damage to organs (kidneys).
Use premixed coolant according toVolvo's recommendations. If concen-trated coolant is used, make sure thatthe coolant mixture is 50% coolantand 50% water of acceptable quality.
Do not mix different types of coolant.
To help ensure sufficient corrosion pro-tection in the system, only use newcoolant when replacing larger compo-nents in the cooling system.
Never run the engine unless the cool-ing system is properly filled. Animproperly filled cooling system couldlead to high temperatures and cracksin the cylinder heads.
High levels of chlorine, chlorides andother salts may cause corrosion in thecooling system.
