If you calculate your average fuel economy by dividing distance traveled
by gallons of fuel used (liters of fuel used by 100 kilometers traveled),
your figure may be different than displayed for the following reasons:
• Your vehicle was not perfectly level during fill-up
• Differences in the automatic shut-off points on the fuel pumps at
service stations
• Variations in top-off procedure from one fill-up to another
• Rounding of the displayed values to the nearest 0.1 gallon (liter)
1. Drive the vehicle at least 5 miles (8 km) with the speed control
system engaged to display a stabilized average.
2. Record the highway fuel economy for future reference.
It is important to press the RESET button (press and hold RESET for
two seconds in order to reset the function) after setting the speed
control to get accurate highway fuel economy readings.
MPG (L/km)
This displays instantaneous fuel economy as a bar graph ranging from ↓
poor economy to ↑ excellent economy.
Your vehicle must be moving to calculate instantaneous fuel economy.
When your vehicle is not moving, this function shows ↓ , one or no bars
illuminated. Instantaneous fuel economy cannot be reset.
TIMER

lubrication. A timer will begin a countdown from 30 seconds. Once the
counter has reached 0 seconds, OK TO DRIVE will be displayed and the
engine will respond to accelerator pedal movement. Refer to your diesel
supplement for more information.
OK TO DRIVE (diesel engine only) — Displayed when the time
