The cruising range is calculated based on the fuel consumption for
the last 18 miles (30 kml. If you drive conservatively, the cruising
range will increase.
Average fuel mileage
The average fuel economy in MPG (1/100 km) since you last c leared
the memory appears in this display . You can use this display to
adjust your driving technique to achieve a desired mileage.
Current fuel mileage
The instantaneous fuel consumption in miles per gallon (1/100 km)
is shown in this display. You can use this display to adjust your
driving technique to achieve a desired mileage.
Fuel consumption is recalculated at intervals of 33 yards (30
metres). When the vehic le is sta tionary, the most recent fuel
consumption is displayed.
Average speed
The average speed in mph (km/h) since the last time the display was
reset appears in the display.
Elapsed time
The length of time that you have been driving since you last reset

The trip computer is equipped with two fully automatic

Fig . 22 Trip computer
display: memory level 1
You can switch between the trip computer 1 and 2 by pressing the
Reset button
@ ~ page 40, fig. 23.
You can tell which memory level is currently active by the number in
the display ~ fig . 22. The data from the single -trip memory
(memory level 1) is being displayed if a
1 appears . If a 2 is shown ,
then the data from the total -trip memory is being disp layed
(memory level 2).
Single-trip memory (Trip computer 1 )
The single-trip memory stores the trip information from the time the
ignition is turned on until it is turned off. If the trip is continued
within 2 hours from the time the ignition was turned off, the new
data will be included in the calculation of the current trip informa­
tion. If the trip is interrupted for
more than 2 hours the memory is
reset automatically.
Total-trip memory (Trip computer 2)
Unlike the single -trip memory, the total -trip memory is not reset
automatically . This permits you to evaluate your driving data for the
entire period between manual resets .•

Current tire pressures are shown in green and yellow numbers. The
meaning of the co lors is as fo llows:
• Green: If current tire pressure and the specified pressure are
approximately the same, the tire pressure is shown in green .
• Yellow : If current tire pressure is too low with respect to specified
pressure, the tire pressure is shown in yellow.
[ i ] Tips
• During the learning period, tire pressure and tire temperature
are not displayed . Horizontal lines --,-- are displayed for pressure
and temperature.
• The tire pressure is shown on the label located either on the
driver's side B-pil lar (visible when the door is open) or inside the fuel
filler flap.
• The tire pressure monitoring system helps the driver to keep an
eye on tire pressures. But the driver still has the responsibility for
maintaining the correct tire pressure. •
Applies to vehicles: with Tire pressure mon itor ing system
Storing tire pressures
Correct storage of specified pressure is the basic require­
men t for reliable tire pressure monitoring.
In order for the tire pressure mo nito ring system to ope rate
appropr iately, yo u have to re -save the specified pressures
whenever yo u adjust tire pressure, for example when the
load condition of your vehicle changes. Proceed as follows:
Corr ecting t ir e pres sure
- Check the pressure in the tires (including the spare tir e*). ~

-Adjust air pressure as needed in acco rdance with the
informat io n on the label located either on the driver's
side B -pillar (visible w hen the door is open), inside the
fuel filler flap and addi tionally in t he manua l.
Saving tir e pres sur es

Selec t
Tire p ressure monitoring.
-Select Store curr. tire pres sures :::} page 44, fig. 27 .
All pressure warning indicators in the display will be canceled .
Following each intentional change in specified pressures, tire pres ­
sures must be resaved .
After the pressures are saved, the tire pressure monitoring system measures the current tire pressures and saves them as the new
specified pressures.
[ i ] Tip s
• T he t ire pressure is shown on the tire pressure label. On USA
vehic les, the tire pressure label is located on the driver's side 8 -
pillar. On Canada vehicles , the tire pressure labe l is located e ither on
the driver's side 8 -pillar or inside the fuel filler flap. The tire pressure
label lists the recommended cold tire inflation pressures for the
vehicle at its maximum capacity weight and the tires that were on
your vehicle at the time it was manufactured . For recommended tire
pressures for normal load conditions, please see chapter
=> page 330 .
• The tire pressure mon itoring system he lps the driver to keep an
eye on tire pressures. But the driver still has the responsibility for
maintaining the correct tire pressure.
