INST ECONOMY
Press SELECT until the menu
displays INST ECONOMY. This will
display your fuel economy in
liters/100 km or miles/gallon based
on the type of traffic you are in.
Your vehicle must be moving to
calculate instantaneous fuel
economy. When your vehicle is not
moving, this function shows 99.9 L/100km or 0.0 MILES/GAL.
Instantaneous fuel economy cannot be reset.
AVG ECONOMY
Press SELECT until the menu
displays AVG ECONOMY. This will
display your average fuel economy
in liters/100 km or miles/gallon.
If you calculate your average fuel
economy by dividing liters of fuel
used by 100 kilometers traveled
(miles traveled by gallons used),
your figure may be different than displayed for the following reasons:
²your vehicle was not perfectly level during fill-up
²differences in the automatic shut-off points on the fuel pumps at
service stations
²rounding of the displayed values to the nearest 0.1 liter (gallon)
Checking your highway fuel economy using the electronic
message center display
Use the following procedure will allow you to accurately monitor your
actual highway fuel economy. This procedure requires the vehicle speed
control system to be set to highway speeds and must be run only on
suitable roadways where long distance speed control can be safely
maintained.
You may notice gradual improvement in fuel economy over the course of
your vehicle's break-in period (approximately 1 600 kilometers [1 000
miles]).
1. Set the speed control. Refer toSpeed controlin theControls and

For consistent results when filling the fuel tank:
²Use the same filling rate setting (low Ð medium Ð high) each time
the tank is filled.
²Allow three automatic click-offs when filling.
²Always use fuel with the recommended octane rating.
²Use a known quality gasoline, preferably a national brand.
²Use the same side of the same pump and have the vehicle facing the
same direction each time you fill up.
²Have the vehicle loading and distribution the same every time.
Your results will be most accurate if your filling method is consistent.
Calculating fuel economy
1. Fill the fuel tank completely and record the initial odometer reading
(in kilometers or miles).
2. Each time you fill the tank, record the amount of fuel added (in liters
or gallons).
3. After at least three to five tank fill-ups, fill the fuel tank and record
the current odometer reading.
4. Subtract your initial odometer reading from the current odometer
reading.
5. Follow one of the simple calculations in order to determine fuel
economy:
Multiply liters used by 100, then divide by total kilometers
traveled.
Divide total miles traveled by total gallons used.
Keep a record for at least one month and record the type of driving (city
or highway). This will provide an accurate estimate of the vehicle's fuel
economy under current driving conditions. Additionally, keeping records
during summer and winter will show how temperature impacts fuel
economy. In general, lower temperatures give lower fuel economy.
Driving style Ð good driving and fuel economy habits
Give consideration to the lists that follow and you may be able to change
a number of variables and improve your fuel economy.
Maintenance and care
221

Habits
²Smooth, moderate operation can yield up to 10% savings in fuel.
²Steady speeds without stopping will usually give the best fuel
economy.
²Idling for long periods of time (greater than one minute) may waste
fuel.
²Anticipate stopping; slowing down may eliminate the need to stop.
²Sudden or hard accelerations may reduce fuel economy.
²Slow down gradually.
²Driving at reasonable speeds (traveling at 88 km/h [55 mph] uses 15%
less fuel than traveling at 105 km/h [65 mph]).
²Revving the engine before turning it off may reduce fuel economy.
²Using the air conditioner or defroster may reduce fuel economy.
²You may want to turn off the speed control in hilly terrain if
unnecessary shifting between third and fourth gear occurs.
Unnecessary shifting of this type could result in reduced fuel
economy.
²Warming up a vehicle on cold mornings is not required and may
reduce fuel economy.
²Resting your foot on the brake pedal while driving may reduce fuel
economy.
²Combine errands and minimize stop-and-go driving.
Maintenance
²Keep tires properly inflated and use only recommended size.
²Operating a vehicle with the wheels out of alignment will reduce fuel
economy.
²Use recommended engine oil. Refer toLubricant Specifications.
²Perform all regularly scheduled maintenance items. Follow the
recommended maintenance schedule and owner maintenance checks
found in your vehicle Scheduled Maintenance Guide.
Conditions
²Heavily loading a vehicle or towing a trailer may reduce fuel economy
at any speed.
