Maintenance and Specifications
Slow down gradually.
Driving at reasonable speeds (traveling at 88 km/h [55 mph] uses 15%
less fuel than traveling at 105 km/h [65 mph]).
Revving the engine before turning it off may reduce fuel economy.
Using the air conditioner or defroster may reduce fuel economy.
You 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.
Warming up a vehicle on cold mornings is not required and may
reduce fuel economy.
Resting your foot on the brake pedal while driving may reduce fuel
economy.
Combine errands and minimize stop-and-go driving.
Maintenance
Keep tires properly inflated and use only recommended size.
Operating a vehicle with the wheels out of alignment will reduce fuel
economy.
Use recommended engine oil. Refer to Lubricant specifications in
this chapter.
Perform all regularly scheduled maintenance items. Follow the
recommended maintenance schedule and owner maintenance checks
found in your vehicle service maintenance section.
Conditions
Heavily loading a vehicle or towing a trailer may reduce fuel economy
at any speed.
Carrying unnecessary weight may reduce fuel economy (approximately
0.4 km/L [1 mpg] is lost for every 180 kg [400 lb] of weight carried).
Adding certain accessories to your vehicle (for example bug
deflectors, rollbars/light bars, running boards, ski/luggage racks) may
reduce fuel economy.
Using fuel blended with alcohol may lower fuel economy.
Fuel economy may decrease with lower temperatures during the first
12–16 km (8–10 miles) of driving.
Driving on flat terrain offers improved fuel economy as compared to
driving on hilly terrain.
