power windows continue to function until
the driver's door or front passenger's door
has been opened.
- Pay careful attent ion when closing the win­
dows . Pinching could cause serious injuries .
- When locking the vehicle from outside, the vehicle must be unoccupied since the win­
dows can no longer be opened in an emer­
gency .
@ Tips
You can still open and close the w indows for
approximately 10 minutes after turning the
ignition
off . The power windows do not switch
off until the driver's door or front passenger's
door has been opened.

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
(D 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 .
80
-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 and restore the full braking ef­
fect .
{CT) 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
85.
@ 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 safe ly .
-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
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 ­
sumpt ion to zero (fuel shut-off dur ing decelera­
tion) .
Shift efficiently
Upshifting earlier is an effective way to save fuel.
Staying in a gear too long uses fuel unnecessari­
ly.
Applies to: vehicles with manual transmission
Shift as soon as possible from first to second
gear. S hifting to the next highest gear at approxi­
mately 2,000 RPMs if poss ible is recommended.
Applies to: vehicles with automatic transmissions
Press down on the acce le rator peda l 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. Driving more slowly saves fuel.
Reduce idling time
The Start/Stop system* he lps 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 cross ings and long
r ed lights. Stopping the engine for 30-40 sec­
onds already saves more fuel than the amount of
extra fuel needed to restart the eng ine.
It takes a very long time in idle to warm the en­
g ine up to operating temperature. Wear and
emissions are especially h igh in the wa rm-up
phase . Therefore, you should begi n driving im­
mediately a fter starting the engine . Avoid high
RPMs while do ing this .
Have maintenance performed regularly
By having maintenance performed regu larly on
your veh icle, yo u ca n he lp to reduce f uel con­
sumption before yo u even start to drive. The
maintenance condition of your vehicle not only
affects traffic safety and long-term value but a l-
Driving
so impacts fuel consumption . A poorly main ­
tained engine can lead to fuel consumption that is 10% higher than norma l.
Avoid short trips
The eng ine and exhaust cleaning system must
reach their optimal operat ing temperatu re to ef­
f ectively reduce consumption and emissions.
A cold engine uses a disproportionately high
amount of fue l. The engine reaches operating
temperat ure and consumption normalizes on ly
after approximate ly 2.5 miles (4 km).
Check the tire pressure
To save fuel, make sure the tires are always in­
flated to the correct press ure
~ page 344. The
fuel consumption can increase by 5% if the pres­
s u re is only 0.5 bar too low. Due to the increased
rolling resistance, low tire pressures wi ll also
l ead 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
S in ce eve ry po und of ext ra weight increases f uel
consumption , a quick inspection of the luggage
compartment may be worth it to avoid unneces ­
sary weight .
When not be ing used , a roof rack should be re­
moved to decrease the wind resistance of the ve­
hicle. This will save you approximately 12% fuel
at speeds from 62 -75 mph (100 - 120 km/h) .
Save energy
The eng ine drives the generator, which generates
electric ity; the fuel consumpt io n also incr eases
with the demand for electr icity. The refore, switch
electrical eq uipment off when you no longer
need it . Examples of equipment that uses a lo t of
energy are air blowers at a high setting, the rear
window defogger and seat heating* .
@ Note
Do not leave engine idling unattended after
starting. If warning lights shou ld come on to
indicate improper operation, they would go
