-Keep in mind that oncoming vehicles may
create waves that raise the water level and
make it too deep for your vehicle to drive
through safely.
-Avoid driving through salt water, because
this can cause corrosion.
Economical and environmentally-friendly
driving
The amount of fuel consumption, the environ­
mental impact and the wear to the engine,
brakes and tires depends mostly on your driving
style. With an anticipatory and economic driving
style, fuel consumption can be reduced by ap­
proximately 10-15%. The following tips will help
you conserve the environment and your money at the same time.
Anticipatory driving
A vehicle uses the most fuel when accelerating.
When you drive with anticipation, you do not
need to brake as often and so you accelerate less.
When possible, let your vehicle coast with a
gear
engaged, for example, when you notice that the
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
Upshifting earlier is an effective way to save fuel.
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/
8 Stop system*, it is efficient to switch the engine 00 \.J ' Driving
off when stopped at railroad crossings and long
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.
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.
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
Q page 215. 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 pound of extra weight increases fuel
consumption, a quick inspection of the luggage
compartment may be worth it to avoid unneces -
sary weight.

A WARNING
To reduce the risk of poisoning, never allow
the engine to run in confined spaces.
(D Note
Avoid high engine speed, full th rottle, 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 immediate ly. This re­
duces unnecessary emissions.
(D Tips
- Some noise after starting the engine is nor­
ma l and is no cause for concern.
- If you leave the veh icle w ith the ignition
switched on, the ignition w ill switch off af ­
ter a certain amount of time . Make sure that
electrical equipment such as the exterior
lights are switched off .
Stopping the engine
.. Bring the vehicle to a full stop .
.. Move the selector lever to the P or N posit io n.
.. Press the I START ENGINE STOP I button

I START ENGINE STOPI button and also press the
brake pedal.
A WARNING
- Never turn off the engine before the vehicle
has come to a complete stop. The full func­
tion of the brake booster and the power
steering is not guaranteed. You may need to
use more force when braking or steering.
Because you cannot brake and steer as you
usually would, this could lead to accidents
and serious injuries.
- Always take the key with you whenever you
leave your vehicle. Otherwise, the engine
could be started or electrical equipment
such 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 risk that the vehicle
could roll unintentionally.
@ Note
If the engine has been under heavy load for
an extended period of time, heat builds up in
the engine compartment after the engine is
switched off and there is a risk of damaging
the engine. For this reason, let the engine run
at idle for approximately two minutes before
shutting it off.
(D Tips
For up to 10 minutes after stopping the en­
gine, the radiator fan may turn on again auto­
matically or it may continue to run (even if
the ignition is switched off) for the following
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.
- Applies to: vehicles with particulate filter:
The emissions control system is heated
through the regeneration process, even if
the engine has not reached its operating
temperature yet.
