Driving
General information
Breaking in
A new vehicle must be broken in for the first 1,000 mi les (1,500 km). Do not drive at speeds
that will exceed 2/3 of the maximum perm itted
engine speed (RPM) for the first 600 miles
(1,000 km), and avoid full acceleration during
this period . You may gradually start increasing
the RPM and the speed between 600 miles (1,000 km) and 1,000 miles (1,500 km) .
During the first hours of use, the engine has a
h igher internal friction than later on when all
moving parts have settled into place with each
other.
How the vehicle is driven during the first 1,000
miles (1,500 km) also affects the engine quality.
Drive at moderate engine speeds after the initial
break-in period, particularly when running a cold
engine. This will reduce engine wear and improve
the mileage .
Do not drive at too low of an engine speed (RPM).
Shift down if the engine stops running "smooth­ ly". Extremely high engine speeds are automati­
cally reduced .
Reducing the risk of vehicle damage
CD Note
When driving on poor roads, by curbs and on
steep ramps, make su re that low-hang ing
components such as the spoi ler and exhaust
system do not come into contact with these
or they could be damaged. This especially ap­
plies to vehicles with low ground clearance
and vehicles that are heavily loaded.
Driving through water on roads
Note the following to reduce the risk of vehicle
damage when driv ing through water, for example
on flooded roads:
-The water must not be any higher than the bot­
tom of the vehicle body .
74
-Do not drive faster than walking speed .
A WARNING
After driving through water or mud, the effec­
tiveness of the brakes may be reduced due to
moisture on the brake rotors and brake pads.
A few careful brake applications should dry
off the brakes.
CD Note
-Vehicle components such as the engine,
transmission, suspension or electrical sys ­
tem can be severely damaged by driving
through water .
-Always switch the Start/Stop system* off
when driving through water
¢page 81.
(i) Tips
-Determine the depth before driving through
water.
-Do not stop the vehicle, drive in reverse or
switch the engine off when driving through
water.
-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
dr iving
The amount of fuel consumption, the environ­
mental impact and the wear to the engine,
brakes and tires depends mostly on your driving
sty le. 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 ..,.

CXl CXl .... N ,.__
N .... 0 N > 00
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.
