STARTING AND DRIVING
354in countries where it may be difficult to obtain the correct fuel.
• Consider your destination. If you will be driv-ing through an area where snow or ice arelikely to occur, consider using snow tires.
Driving economically
Better driving economy can be obtained by thinking ahead, avoiding rapid starts and stopsand adjusting the speed of your vehicle to imme-diate traffic conditions.
Economical driving conserves natural resources
Observe the following rules: • Bring the engine to normal operating tem- perature as soon as possible by driving witha light foot on the accelerator pedal for thefirst few minutes of operation. A cold engineuses more fuel and is subject to increasedwear.
• Whenever possible, avoid using the vehiclefor driving short distances. This does notallow the engine to reach normal operatingtemperature.
• Drive carefully and avoid rapid accelerationand hard braking.
• Use the transmission's Drive (
D) position as
often as possible and avoid using kick-down.
• Using the engine's Eco function can helpimprove fuel economy.
• Do not exceed posted speed limits.
• Avoid carrying unnecessary items (extra load)in the vehicle.
• Maintain correct tire pressure. Check tirepressure regularly (when the tires are cold). •
Use tires recommended by Volvo for yourvehicle.
• Remove snow tires when threat of snow orice has ended.
• Note that roof racks, ski racks, etc, increaseair resistance and also fuel consumption.
• At highway driving speeds, fuel consumptionwill be lower with the air conditioning on andthe windows closed than with the air condi-tioning off and the windows open.
• Using the onboard trip computer's fuel con-sumption modes can help you learn how todrive more economically.
Other factors that decrease gas mileage are:
• Dirty air cleaner
• Dirty engine oil and clogged oil filter
• Dragging brakes
• Incorrect front end alignment
Some of the above mentioned items and othersare checked at the standard maintenance inter-vals.
Handling and roadholding
• Vehicle load, tire design and inflation pres-sure all affect vehicle handling. Therefore,check that the tires are inflated to the rec-ommended pressure according to the vehicleload. Loads should be distributed so that

Overheating the engine and transmission
In demanding driving conditions, such as when transporting heavy loads, driving in mountainousareas or in very hot weather there is a risk ofoverheating the engine or transmission.
• The engine's output may be slightly limited if there is a risk of overheating.
• Remove e.g., auxiliary lights mounted in frontof the grille in hot weather.
• If the temperature of the engine coolantbecomes too high, the warning symbol will illuminate and the message
Engine
temperature/Stop safely will be displayed.
Stop the vehicle as soon as possible in a safe place and let the engine idle for severalminutes.
• If the message
Engine temperature/High
temperature Turn off engine or Engine
coolant/Stop safely is displayed, stop
safely and turn off the engine.
• If the transmission begins to overheat, an alternative gear shifting program will beselected. An integrated protective functionwill also by activated, the warning symbol will illuminate and the message
Transmission
warmHigh temperature Reduce speed
or Transmission warmStop safely, wait
for cooling will be displayed in the instru-
ment panel. •
The air conditioning may be switched off temporarily.
• After a prolonged period of driving, do notturn off the engine immediately after stop-ping.
• The engine cooling fan commonly continuesto run for several minutes after the enginehas been turned off.
WARNING
The cooling fan (located at the front of the engine compartment, behind the radiator) maystart or continue to operate (for up to6 minutes) after the engine has beenswitched off.

Automatically connecting to a workshop
Without driver confirmation
This is the most convenient way to transmit trou- ble-shooting data. The driver does not need toconfirm that the vehicle will establish a connec-tion. If the vehicle stops at a workshop and the engine is switched off using the start knob, a messagewill appear above the status bar in the center dis-play. The vehicle will be automatically connectedwhen the driver's door is opened if the driver does not tap the
Cancel button in the message.
To help prevent the driver from being disturbed by unwanted requests to connect (e.g., if thevehicle is often parked near a workshop with anauthorized Volvo network), the vehicle will switchto manual connection if the driver cancels a con-nection request twice within 5 days.
With driver confirmation
With this alternative, the driver must confirm a connection. If the vehicle stops at a workshop and the engine is switched off using the start knob, a pop-upwindow will open in the center display. The vehi-cle will be automatically connected when the driv- er's door is opened if the driver taps
Connect in
the pop-up window. If the driver does nothing or taps the pop-up window's
Abort button, no
attempt will be made to establish a connection.
NOTE
To help prevent the driver from being distur- bed by unwanted requests to connect (e.g., ifthe vehicle is often parked near a workshopwith an authorized Volvo network), the vehiclewill switch to manual connection if the drivercancels a connection request twice within5 days.
Manually connecting to a workshopManual connections are handled by the service technician.
Changing the way a connection is madeThe type of connection (manual or automatic)can be changed in the center display's Settingsmenu.
1. Pull down the center display's Top view and
