[ i] Tips
• The engine oil pressure symbol 9:::r. is not an indicator for a low
engine oil level. Do not rely on it. Instead, check the oil level in your
engine at regular intervals, preferably each time you refuel, and
always before going on a long trip.
• The yellow oil level warning indication · requires oil refill or
workshop service without delay. Do not wait until the red oil pres­
sure warning symbol
9:::r. starts to flash before you respond to the
low oil level warning . By then, your engine may already have
suffered serious damage. •

Driver inf ormation sy ste m
To ta l-tr ip mem ory ( Trip compu te r 2)
Unlike the single -trip memory, the total -tr ip memory is not reset
automatically . This permits you to evaluate your driving data for the
entire period between manua l resets.
Fu el r an ge
The estimated cruising range in miles (km) appears in the display.
This tells you how far your vehicle will be able to travel on the
current tank of fuel and with the same driving sty le . The display
changes in increments of 6 miles (10 km).
The cruising range is calculated based on the fuel consumption for
t he last 18 miles (30 km). If you drive conservatively, the cruising
range will increase .
Average fuel m ile ag e
The average fuel economy in MPG (1/100 km) since you last cleared
the memory appears in this display. You can use this display to
adjust your driving technique to achieve a desired mileage.
C ur rent fuel mil eage
The instantaneous fuel consumption in mi les per gallon (1/100 km)
is shown in th is d isplay. You can use this display to adjust your
driving technique to achieve a desired mileage.
Fue l consumption is recalcu la ted at intervals of 33 yards (30
meters). When the vehicle is stationary, the most recent fuel
consumption is d isplayed .
Average speed
The average speed in mph (km/h) s ince the last time the display was
reset appears in the display .
Elap se d time
The length of time that you have been driving since you last reset
the memory appears in this display.
Di stance
The elapsed distance since the last time the memory was cleared
appears in the display. The maximum distance that can be recorded
is 9,999 .9 miles (9,999 .9 kilometers).
[ i ] Tips
• Fuel consumptions (average and current), range and speed are
displayed in metric units on Canadian models.
• All stored values will be lost if the vehicle battery is
disconnected .•
Operation
The trip computer is controlled by two switches on the
windshield wiper lever.

Tire pressure monitoring system
General notes
As an added safety feature, your vehicle has been equipped with a
tire pressure monitoring system (TPMS) that illuminates a low tire
pressure telltale when one or more of your tires is significant ly
under -inflated. The TPMS only provides a low tire pressure warning
and does not reinflate your tires.
Accordingly, when the low tire pressure tellta le illuminates, you
should stop and check your tires as soon as possib le, and inflate
them to the proper pressure. Driving on a significantly under­
inflated t ire causes the tire to overheat and can lead to tire failure .
Under -inflation a lso reduces fuel efficiency and tire tread l ife, and
may affect the vehicle's handling and stopping ability.
(D Note
• Please note that the TPMS is not a substitute for proper tire
maintenance, and it is the driver's respons ib ility to maintain correct
tire pressure, even if under -inflation has not reached the level to
trigger illumination of the TPMS low tire pressure telltale .
• Each tire, including the spare, should be checked monthly when
cold and inflated to the inflat ion pressure recommended by the
vehic le manufacturer on the vehicle p lacard or tire inflation pres ­
s u re label. (If your vehicle has tires of a different size than the size
indicated on the vehicle placard or tire inflation pressure labe l, you
should determine the proper tire inflation pressure for those
tires.) •
TPMS malfunction indicator
Your vehic le has a lso been equipped with a TPMS malfunction indi­
cator to indicate when the system is not operating proper ly . The
TPMS malfunction indicator is combined with the low tire pressure _.,
