Economical driving conserves natural
resources
Better driving economy may be obtained by
thinking ahead, avoiding rapid starts and stops
and adjusting the speed of your vehicle to
immediate traffic conditions. Observe the fol-
lowing rules:
• Bring the engine to normal operating tem-
perature as soon as possible by driving
with a light foot on the accelerator pedal for
the first few minutes of operation. A cold
engine uses more fuel and is subject to
increased wear.
• Whenever possible, avoid using the vehicle
for driving short distances. This does not
allow the engine to reach normal operating
temperature.
• Drive carefully and avoid rapid acceleration
and hard braking.
• Do not exceed posted speed limits.
• Avoid carrying unnecessary items (extra
load) in the vehicle.
• Maintain correct tire pressure. Check tire
pressure regularly (when tires are cold).
• Remove snow tires when threat of snow or
ice has ended.
• Note that roof racks, ski racks, etc,
increase air resistance and also fuel con-
sumption.
• Avoid using automatic transmission kick-
down feature unless necessary.
• However, at higher driving speeds, fuel
consumption will be lower with the air con-
ditioning on and the windows closed than
with the air conditioning off and the win-
dows open.
• Using the onboard trip computer's fuel
consumption modes can help you learn
how to drive more economically.
Other factors that decrease gas mileage are:
• Dirty air cleaner
• Dirty engine oil and clogged oil filter
• Dragging brakes
• Incorrect front end alignment.
Some of the above mentioned items and others
are checked at the standard Maintenance
Service intervals.
NOTE
Vehicles equipped with automatic transmis-
sions should use (D)rive as often as possible
and avoid using "kickdown" to help improve
fuel economy.
CAUTION
Drive slowly and carefully if going through
standing water (i.e. flooded roadways, etc.).
Damage to the engine could result if excess
water is drawn in through the air intake sys-
tem. Never drive the vehicle in water deeper
than 1 foot (300 mm).
