200 Driving and en vir onm ent
You must drive your vehicle about 3,000 miles
(5,000 kilometers) before you can properly
assess o il consumption.
This a lso applies to fuel consumption and en­
gine output.
0 Note
- Have yo ur vehicle maintained properly
and in accordance with the service rec­
ommendations in your Warranty
& Main ­
tenance booklet. Lack of proper mainte­
nance as well as improper use of the ve­
hicle will impair the funct ion of the
emission control system and could lead
to damage .
- Do not alter or remove any component of
the Emi ssion Control System unless ap­
proved by the manufacturer .
- Do not alter or remove any dev ice, such
as heat shields, switches, ignition wires,
valves, wh ich are designed to protect
your vehicle's Emiss ion Control System
and othe r important veh icle compo­
nen ts.
Fewer short trips
Fuel consumption will always be relatively
high on short trips .
.. Try to avo id driving short d istances with a
co ld eng ine .
The engine and ca talytic conver ter have to
reach their optimal
op erating temp eratur e to
reduce fuel consumption and noxious emis­
sions effect ively.
Jus t after s tarting, a cold engine in a mid-size
car only achieves a fuel economy of 6 -8 miles
per gallon (30-40 l/100 km) . After about a
ha lf a m ile, fue l economy climbs to 12 mpg
(20 l/100 km). Afte r abo ut
2 .5 m iles (4 km),
the eng ine is at its proper ope rat ing tempera­
ture and fue l economy has reached a norma l
l eve l. So you can see that you should avoid
short trips whenever possib le . T
he
ou tsid e tempe rature is also critical in this
regard . Your car consumes more fue l in the
winter than in the summer.
