Avoid full acceler ation
You sho uld rare ly t rave l a t t he maxim um vehicle
speed . High speeds cause a disproportionately
h igh increase in fuel consumption, emissions and
traffic noise . Slower driving saves fuel.
Reduce idling time
It pays off to stop the eng ine, for example when
at ra ilroad crossings or traffi c lights w ith longer
red lights . Stopping the engine for 30 -40 sec­
onds already saves more fuel than the amount of
extra fuel needed to restart the engine.
I t takes a very long time in idle to wa rm the en­
gine up to operating tempera ture . Wea r and
emissions are especially high in the warm -up
p hase . Therefore, you should begin driving im ­
mediately after starting the engine. Avoid high
RPMs while do ing th is.
Hav e ma intenanc e performed r egularly
By having maintenance performed regu lar ly on
your vehicle, you can he lp to reduce fuel con ­
sumption before yo u even start to drive. The
maintenance condition of your vehicle not only
affects traffic safety and long-term va lue but al­
so impacts
fu el con sumpt ion .
A poorly maintained engine can lead to fuel con ­
sumpt ion that is 10% higher than norma l.
A lso check the
o il l evel when refueling . The oil
consumpt ion
depends large ly on the engine load
and speed. It is normal for the oil consumption
of a new eng ine to reach its lowest point only af­
ter a certain amount of use. Therefore, the oil
consumption can only be properly judged after
approx imately 3,000 m i (S,000 km) have been
driven.
Avoid short trips
The engine and exhaust clean ing system must
reach their opt imal
op erating temp eratur e to ef­
fective ly reduce consumpt ion and emiss ions.
A co ld engine uses a disproportionately h igh
amount of fuel. The eng ine reaches operating
temperature and consumpt ion normalizes only
afte r approx imately
2.5 miles (4 km) .
Driving
@ Note
Do not leave engine idling unattended after
start ing. If warning lights sho uld come on to
i ndicate improper operation, they would go
unheeded. Extended idling also produces
heat, which could resu lt in overheating or
other damage to the veh icle o r other proper­
ty.
@ Note
- Have your ve hicle ma intained properly and
in accordance w ith the service recommenda­
tions i n your Warranty
& Main tenance book­
let. La ck of prope r mai nte nan ce as we ll as
imp rope r use of t he ve hicle will impa ir the
function of the em iss ion cont ro l system and
co uld lead to damage .
- Do not alte r or remove any compone nt o f
t he Emission Contro l System unless ap ­
proved by the man ufacturer .
- Do not alte r or remove any dev ice, s uch as
heat shields, switc hes, ignition wires,
valves, which are designed to protect your
vehicle's Emission Contro l System and other
impo rtant ve hicle components.
(D Tips
The cons umption estimates as published by
ENVIRONMENTAL PROTECTION AGENCY
(EPA) and T ransport Canada may not co rre­
spond to your actual consumption on the r oad, wh ich w ill vary depending upon veh icle
