the climate control system runs continuously at
maximum cooling or heating power. There is no
temperature regulation.
Synchronization : by pressing the AUTO button
for two seconds, the temperature setting for the
driver's side is transferred to the front passeng­
er's side. This applies a temperature change to
the front passenger's side.
Be Blower
Using the regulator 8ft, you can manually adjust
the volume of air generated by the blower to your
preference.
Use the left
8ft butto n to decrease the air speed,
and use the right
8ft button to increase the air
speed .
The blower should always run at a low setting to
prevent the windows from fogging and to ensure
a continuous exchange of a ir inside the vehicle.
To have the airflow regulated automatically,
press the AU TO button.
!,.i /:,0/!,DAir distribution and vents
The air distr ibut ion can adjusted with the but­
tons. To have the air dist rib ut ion regulated a uto­
matica lly, press the AUTO button.
You can open or close the center and rear vents in
the cockpit and the vents in the rear center con ­
sole using the r idged thumbwheels . T he levers
adjust the direction of the airflow from the vents .
To keep the front s ide windows from fogging up
in damp weathe r, we recommend opening the
side air vents and tilting them to the side.
~ MAX Defrosting
The windshield and side windows are defrosted
or cleared of condensation as quickly as possible.
The maximum amount of air flows mainly from
the vents below the windshie ld. Recirculation
mode switches off. The temperature should be
set at +72°F (22°() or highe r.
The AUTO button sw itches the defroster off.

~A Recirculation mode
To switch on the recircu lation mode, press the
~A button . The lower LED in the button turns
on .
In rec ircu lation mode, the air inside the vehicle is
circulated and filtered. This prevents the unfi l­
tered air outside the vehicle from entering the
vehicle interior. Switching recirculat ion mode on
when driving through a tunnel or when sitting in
traffic is recommended
¢ ,&..
The AU TO button or@ button switches recircula­
tion mode off.
T o switc h on the automatic recirculation mode,
press the
~A button again. The upper LED in the
button turns on. The system switches to recircu­
lation mode when driving in reverse when the en­
gine is cold. The air quality sensor that is de­
s igned for diese l and gasoline exhaust automati­
ca lly switches the recirculation mode on or off
depending on the level of pollutants in the out­
s ide air . Automatic rec irculat ion mode is time re­
stricted when cooling mode (A/C) is sw itched off
and frost temperatures are ide ntif ied.

Driving
General information
Breaking in
A new vehicle must be broken in for the first
1,000 mi les (1,500 km). For the first 600 miles
(1,000 km), do not drive at speeds that are more
than 2/3 of the maximum permitted RPM, avoid
full acce leration, and do not tow a trailer . 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
higher internal friction than later on when all
moving parts have settled into p lace 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 initia l
break-in period, particularly when running a cold
engine . This will reduce eng ine wear and improve
the m ileage .
Do not drive at too
low of an engine speed (RPM).
Shift down if the engine stops running "smooth­ ly". Extremely high eng ine speeds are automati­
cally reduced.
Reducing the risk of vehicle damage
([) Note
When driving on poor roads, by curbs and on
steep ramps , make su re that low-hang ing
components such as the spoiler 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.
D riving
- Do not drive faster than walking speed.
A WARNING
After driv ing 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 .
(D Note
Vehicle components such as the engine,
transmission, suspension or electrical system
can be severely damaged by driving through
water.
(D 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 oncom ing vehicles may
create waves that raise the water level and
make it too deep for your vehicle to drive
through safely.
- Avoid dr iving through salt water, because
this can cause corrosion .
Economical and environmentally-friendly
driving
T he amount o f 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 examp le when you notice that the
next t raffic light is red. This produces an engine
llll-

Driving
braking effec t, which he lps to protect the brakes
and tires and reduces the emissions and fuel con­
sumpt ion to zero (fuel shut-off during dece lera­
tion) .
Shift effici en tly
Upshift ing earlier is an effective way to save fuel.
Staying in a gear too long uses fue l unnecessari ­
ly.
P ress down o n the acce le ra tor peda l slowly and
avoid " kick -down ".
Avoid full acceleration
You should rare ly trave l at the maximum vehicle
speed. High speeds cause a d isproportionately
h igh inc rease in fuel consump tion, emissions and
tr affic no ise. Slower driving saves fuel.
Reduce idling time
There are benefits to stopp ing the engine, for ex ­
ample when at railroad crossings or traffic lights
with longer red lights. Stopping the engi ne for
30 -40 seconds already saves mo re fuel than the
amount of extra fuel needed to restart the en­
gine.
It takes a very long time in idle to wa rm the en­
g ine up to ope ra ting tempe ra tu re. Wea r and
emissions are especially high in the wa rm -up
phase . Therefore, yo u should begi n driving im ­
mediately after starting the engine. Avoid high
RP Ms while doing t his .
Have maintenance performed r egularly
By having m ainten ance perfo rmed regu larly on
your ve hicle, yo u can he lp to reduce f uel con­
sumpt ion befo re yo u even start to dr ive. The
maintenance condition of your vehicle not only
affects traffic safety and long-te rm value but a l­
so impacts
fuel consumpt ion . A poorly main­
tained engine can lead to fuel consumption that
is 10% higher than normal.
Also check th e
oil level when refueling . T he oil
consumption
depends large ly on the engine load
and speed. It is normal for the oil consumpt ion
of a new eng ine to reach its lowest point only af ­
ter a certain amount of use. Therefo re, the oil
consumpt ion can o nly be properly judged after
58
approximately 3,0 00 miles (S,000 km) have been
driven .
Avoid short trips
The eng ine and exhaust clean ing system mus t
r each their optima l
operating temperature to ef­
fe ct ively reduce consump tion and emissions.
A cold engine uses a d isp roportionately high
amount of fue l. The engine reac hes operat ing
temperat ure and cons umption no rmal izes on ly
a fter approximate ly 2.5 m iles (4 km) .
Check the tire pressure
To save fuel, make sure the t ires are always in­
flated to the correct pressure ~
page 175. The
fuel consumpt ion can increase by 5% if the p res ­
s ur e is on ly 0.5 bar too low. Due to the i ncreased
rol ling resis tance, low tire p ressures w ill also
l ead to greater tire
wear and will affect driving
behavior .
Do no t drive on
winter tir es ye ar-r ound, as this
will consume up to 10% more f uel.
Eliminate unnecessary weight
S ince every po und of ext ra weight increases fuel
consump tion , a quick inspect io n of the luggage
compartmen t may be wo rth it to avoid unneces ­
s ar y we ight.
When not be ing used, a roof rack shou ld be re­
moved to decrease the w ind resistance of the ve­
hi cle. This will save yo u ap prox imately 1 2% fue l
at speeds from 62 -75 mph (100 -12 0 km/h).
Save energy
The eng ine drives the generator, which generates
e lectric ity; the fuel consumpt io n also increases
with t he demand for e lectricity . T he refore, sw itch
electrica l eq uipm ent off whe n you no longe r
need i t. Exa mples of eq uipme nt tha t uses a lo t of
energy a re air blowe rs at a high setting, the rea r
window defogger and seat heating* .
([) Note
-Do not leave engine idling un attended afte r
sta rting. If warn ing li ghts should come on
to ind icate improper ope ration, they wou ld
go unheeded . Extended idling also pro duces .,.
