engaged - for example, when you notice that the
next traffic light is red.
Avoid full acceleration
You should rarely travel at the maximum vehicle
speed. High speeds cause a disproportionately
high increase in fuel consumption, emissions and
traffic noise. Slower driving saves fuel.
Reduce idling time
The idling phase is automatically reduced for
vehicles with the Start-Stop system*. In vehicles
without the Start-Stop system*, it is efficient to
switch the engine off when stopped at railroad
crossings and long red lights. Stopping the en-
gine for 30-40 seconds already saves more fuel
than the amount of extra fuel needed to restart
the engine.
It
takes a very long time in idle to warm the en-
gine up to operating temperature. Wear and
emissions are especially high in the warm-up
phase. Therefore, you should begin driving im-
mediately after starting the engine . Avoid high
RPMs while doing this .
Service regularly
By servicing your vehicle regularly , you can help
to reduce fuel consumption before you even start
to drive. The maintenance condition of your vehi-
cle not only affects traffic safety and long-term
value but also impacts fuel consumption.
A poorly serviced engine can lead to fuel con-
sumption that is 10% higher than normal.
Also check the oil level when refueling. The oil
consumption depends largely on the engine load
and speed. It is normal for the oil consumption
of a new engine to reach its lowest point only af-
ter a certain amount of use. Therefore, the oil
consumption can only be properly judged after
approximately 3,000 mi (5,000 km) have been
driven.
Avoid short trips
The engine and exhaust cleaning system must
reach their optimal operating temperature to ef-
fectively reduce consumption and emissions.
Driving
A cold engine consumes a disproportionately
high amount of fuel. The engine is at operating
temperature and consumption has normalized
only after approximately four kilometers.

Note
Do not leave engine idling unattended after
starting. If warning lights should come on to
indicate improper operation, they would go
unheeded. Extended idling also produces
heat, which could result in overheating or
other damage to the vehicle or other proper-
ty.
CD
Note
- Have your vehicle maintained properly and
in accordance with the service recommenda-
tions in your Warranty & Maintenance book-
let. Lack of proper maintenance as well as
improper use of the vehicle will impair the
function of the emission control system and
could lead to damage.
- Do not alter or remove any component of
the Emission Control System unless ap-
proved by the manufacturer.
- Do not alter or remove any device, such as
heat shields, switches, ignition wires,
valves, which are designed to protect your
vehicle's Emission Control System and other
important vehicle components.

Tips
The consumption estimates as published by
ENVIRONMENTAL PROTECTION AGENCY
(EPA) and Transport Canada may not corre-
spond to your actual consumption on the
road, which will vary depending upon vehicle
load and speed, road and weather conditions,
trip length, etc.
