TIPS AND ADVICE
dih Do not
carry
unnecessary items
~ in the luggage compartment.
Particularly in city traffic where you must
often accelerate, weight influences fuel
consumption.
dih Remove supplementary roof
1!1$$
rack components when not in
use.
At high road speeds, the increased air re-
sistance caused by the cross bars also in-
creases fuel consumption.
dih Switch off any electrical equip-
~ ment when no longer
needed.
The rear window defogger, additional driv-
ing lights and the heater blower consume a
lot of electricity. The more electricity you
consume, the higher the fuel consumption.
For example, if you keep the rear window
defogger on for 1 0 hours, your fuel con-
sumption will increase by about 1 quart (1
liter).
dih Check your vehicle's fuel con-
~ sumption regularly. Keep a writ-
ten record or use
the trip
odometer.
Check your fuel consumption each time you
refuel. By doing this, you can discover any
inconsistencies which could result in in-
creased fuel consumption and have these
checked before other problems appear.
• Check your oil each time you fill
your tank
The amount of oil used is related to engine
load and speed.
It is normal for the oil consumption of a new (
engine to reach its lowest value after a cer-
tain mileage has been driven.
You must drive your vehicle about 3,000
miles (5 000 kilometres) before you can
properly assess oil consumption.
This also applies to fuel consumption and
engine output.
e The published ENVIRONMENTAL
PROTECTION AGENCY (EPA) and
Transport Canada consumption esti-
mates may not correspond to your
actual consumption on the road, (
which will vary depending upon ve-
hicle load and speed, road and
weather conditions, trip length, etc.
The catalytic converter is an efficient
"clean-up" device built into the exhaust
system of the vehicle. The catalytic convert-
er burns many of the pollutants in the ex-
haust gas before they are released into the
atmosphere.
Using unleaded fuel is critically im-
portant for the life of the catalytic
converter and proper functioning of
the engine - see page 4.
