next traffic light is red. This produces an engine
braking effect, which helps to protect the brakes
and tires and reduces the emissions and fuel con­
sumption to zero (fuel shut-off during decelera­
tion).
Shift efficiently
An effective way to save fuel is to upshift earlier.
Staying in a gear too long uses fuel unnecessari­
ly .
Press down on the accelerator pedal slowly and
avoid "kick-down".
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 Start/Stop system* helps to reduce the idling
time automatically. In vehicles without the Start/
Stop system, it is efficient to switch the engine
off when stopped
at railroad crossings and long
red lights. Depending on the version of the en­
gine, stopping the engine for as little as five sec­
onds once it has reached operating temperature
still saves more fuel than leaving the engine run­ ning
-even when taking into account the amount
of extra fuel that is used 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.
Have maintenance performed regularly
By having maintenance performed regularly on
your vehicle, you can help to reduce fuel con­
sumption before you even start to drive. The maintenance condition of your vehicle not only
affects traffic safety and long-term value but al­
so impacts
fuel consumption. A poorly main­
tained engine can lead to fuel consumption that
is 10% higher than normal.
Driving
Avoid short trips
The engine and emissions control system must
reach their optimal
operating temperature to ef­
fectively reduce consumption and emissions.
A cold engine uses a disproportionately high
amount of fuel. The engine reaches operating
temperature and consumption normalizes only
after approximately 2.5 miles (4 km).
Check the tire pressure
To save fuel, make sure the tires are always in­
flated to the correct pressure
r=;, page 33 5. The
fuel consumption can increase by S% if the pres­
sure is only 0.5 bar too low. Due to the increased
rolling resistance, low tire pressures will also
lead to greater tire
wear and will affect driving
behavior.
Do not drive on
winter tires year-round, as this
will consume up to 10% more fuel.
Eliminate unnecessary weight
Since every kilogram of extra weight increases
fuel consumption, a quick inspection of the lug­
gage compartment may be worth it to avoid un­
necessary weight.
When not being used, a roof rack should be re­
moved to decrease the wind resistance of the ve­
hicle. You will save approximately 12% of your
fuel when at speeds from 62-75 mph
(100-120 km/h).
Save energy
The engine drives the generator, which generates
electricity; the fuel consumption also increases
with the demand for electricity. Therefore, switch
electrical equipment off when you no longer
need it. Examples of equipment that uses a lot of
energy are air blowers at a high setting, the rear
window defogger and seat heating*.
(D 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

Driving
_& WARNING
-Never turn off the engine before the vehicle
has come to a complete stop. The full func­
t ion of the brake booster and the power
steering is not guaranteed. Yo u must use
more force to turn or brake. Because you
cannot steer and brake as you usually
would, this could lead to accidents and ser i­
ous injuries.
- Never remove the ignit ion key from the ign i­
tion lock while the vehicle is moving. Other ­
wise, the steering lock cou ld sudden ly en­
gage and you would not be able to steer the
vehicle.
- Always take the key with you whenever you
leave your vehicle. Otherw ise, the engine
could be started or electrical equipment
suc h as the power windows could be operat­
ed . This can lead to serious injury.
- For safety reasons, always park the vehicle
with the selector lever in the P position .
Otherwise, there is the r isk that the vehicle
could roll unintentionally.
(D Note
If the engine has been under heavy load for
an extended per iod of t ime, heat builds up in
the engine compartment after the engine is
sw itched off and there is a risk of damaging
the engine. For this reason, let the engine run
for at idle for approximately two minutes be­
fore shut ting it off.
(0 Tips
For up to 10 minutes after stopping the en­
gine, the rad iator fan may turn on again auto­
matically or it may continue to run (even if
the is ignition switched off) due to the follow­
ing reasons:
- The coolant temperature is increasing due
to trapped heat.
- If the engine is warm and the engine com­
partment also heats up from strong sun ­
light.

A WARNING
To reduce the risk of poisoning, never allow
the engine to run in confined spaces.
@ Note
Avoid high engine speed, full throttle, and
heavy engine load if the engine has not
reached operating temperature yet. You could
damage the engine.
@ For the sake of the environment
Do not let the engine run while parked to
warm up. Begin driving immediately. This
re­
duces unnecessary emissions.
(D Tips
-Some noise after starting the engine is nor­
mal and is no cause for concern.
- If you leave your vehicle with the ignition
switched on, the ignition will switch off

Start/Stop system
Description
Applies to: vehicles with Start/Stop system
The Start/Stop system can help increase fuel
economy and reduce CO2 emissions.
In Start/Stop mode, the engine shuts off auto ­
matically when the vehicle is stopped, such as at
a traffic light. The ignition remains switched on
during this stop phase. The engine w ill restart
automat ically when needed.
The Start/Stop system is automat ically act ivated
as soon as the ignition is switched on.
Basic requirements for Start/Stop mode
-The driver's door must be closed .
- The driver's seat belt much be fastened.
- The hood must be closed.
- The vehicle must have driven faster than
2 mph
(3 km/h) since the last time it stopped.
(D Note
Always switch the Start/Stop system off when
driving through water

(D Tips
The engine stops shortly before the veh icle
comes to a stop
