:E: ' Warm and cold Climate control system
Description
A ppl ies to: ve hicles wit h 3-z on e del uxe automatic cl imate
co ntrol or 4 -zo ne de luxe automa tic cl imate co ntr ol
The climate control system warms, cools and re­
moves humidity from the air in the vehicle interi­
or . It is the most effective when the windows and
sunroof* are closed. If there is a bui ld-up of heat
inside the veh icle, ventilat ion can help to speed
up the cooling process.
In all heating mode functions except for
defrost,
the blower on ly switches to a higher speed once
the eng ine coolant has reached a sufficient tem­
perature.
Pollutant filter
The pollutant filter removes pollutants such as
dust and pollen from the air .
Key recognition
The climate control settings are automatically
stored and assigned to the remote control key
that is in use.
Warm and cold
(®} For the sake of the environment
-If you would like to reduce fuel consump­
tion, switch the air conditioning off. This
will also reduce emissions.
- In vehicles with a diesel engine, you can
switch the auxiliary heater off in the Info­
tainment system.
(D Tips
-To prevent interference with the heating
and cooling output and to prevent the win­
dows from fogging over, the air intake in
front of the windshield must be free of ice,
snow or leaves.
- Condensation from the cooling system can
drip and form a puddle of water under the
vehicle. This is normal and does not mean
there is a leak.
- The energy management system may tem­
porarily switch off certain functions, such as
the seat heating* or rear window defogger.
These systems are available again as soon
as the energy supply has been restored.

General information
Breaking in
A new vehicle must be broken in for the first
1,000 mi les (1,500 km). Do not dr ive at speeds
that will exceed 2/3 of the maximum permitted
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
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, suspens ion or electrical sys-
tem can be severely damaged by driving
through water.
- Always switch the Start/Stop system" off
when driving through water¢
page 84.
(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 oncoming vehicles may
create waves that raise the water level and
make it too deep for your vehicle to drive
through safely.
- Avoid driv ing through salt water, because
this can cause corrosion.
Economical and environmentally-friendly
driving
T he amount o f fuel consumpt ion, the environ­
mental impact and the wear to the engine,
brakes and tires depends mostly on your driving
style. With an ant icipatory 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 ..,.

Driving
engaged, for examp le when you notice that the
next traffic light is red . This produces an engine
braking effect, wh ich helps to protect the brakes
and tires and reduces the emissions and fuel con­
sumpt ion to zero (fuel shut-off during decelera­
tion) .
Shift efficientl y
Upshifting earlier is an effective way to save fuel.
Staying in a gear too long uses fue l unnecessari­
ly .
Press down on the acce lerator peda l slowly and
avoid "k ick -down".
Avoid full acceleration
You sho uld rarely t ravel a t the maximum vehicle
speed. High speeds cause a disp ropor tionately
h igh increase in fuel consumption, emissions and
traffic noise . Driving more slowly saves fue l.
Reduce idling time
The Start/Stop system* helps to reduce the id ling
time automatically. In vehicles wi tho ut the Start/
Stop system*, it is efficient to switch the engine
off when stopped at rai lroad 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 eng ine.
I t takes a very long time in idle to wa rm the en ­
gine up to operating temperature . Wear and
emissions are especially high in the wa rm -up
phase. Therefore, yo u should begin driving im­
mediately after starting the engine. Avoid high
RPMs while do ing th is .
Have ma intenance performed regularly
By having maintenance performed regu larly on
your veh icle, you can help to reduce f uel con­
sumpt ion before yo u even start to dr ive. The
maintenance condition of your vehicle not only
affects traffic safety and long -term value but a l­
so impacts f uel consumption . A poorly main­
tained engine can lead to f uel consumpt ion that
is 10% higher tha n normal.
80
Avoid short trips
The eng ine and exh aust clean ing syste m mus t
r each their op tima l operating temperatu re to ef­
fectively reduce consumption and emissions.
A cold engine uses a d isp roportion ately high
amoun t of fue l. The e ngine re aches opera ting
temperat ure and cons umption norma lizes on ly
after approximate ly 2.S mi les ( 4 km).
Check the tire pressure
To save fue l, ma ke sure the t ires are always in­
flated to the corre ct press ure
~ page 343. The
f uel consumpt ion c an increase by S% if the p res­
s ur e is only 0 .S bar too low. Due to the inc reased
rol ling resistance, low tire pressures w ill 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 f ue l.
Eliminate unnecessary weight
Since eve ry po und of ext ra weight increases f uel
consump tion, a quick inspect io n of the luggage
compartment may be wo rth it to avoid unneces ­
sary weight .
When not be ing used, a roof ra ck sho uld be re­
moved to decrease the w ind resis tance of the ve­
hicle . This will save yo u approx ima tely 12% fue l
at speeds from 62 -7S mph (100 -120 km/h) .
Save energy
The engine d rives the generator, which generates
electri city; the f uel consumpt ion also increases
with t he deman d for e lec tricity . T he refore, sw itch
electrica l eq uipment o ff when you no longe r
need it . Examples of eq uipment that uses a lot of
energy are air blowers at a high setting, the rear
window defogger and seat heating* .
CJ) Note
Do not leave engine idling unattended after
starting. If warning lights s hould come on to
i ndicate imprope r operation, they would go
unheeded. Extended idling also prod uces
h eat, which could result in overheating or
other damage to the vehicle or othe r proper­
ty .

@ 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 the vehicle with the ignition
switched on, the ignition will switch off af­
ter a certain amount of time. Make sure that
electrical equipment such as the exterior
lights are switched off.

be turned off while driving at speeds starting at
4 mph (7 km/h) . To switch the engine off, press
the
! START ENGINE STOPI button twice in a row
briefly or press and hold for longer than two sec­
onds.
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 must use
Driving
more force to turn or brake. Because you
cannot steer and brake as you usually
would, this could lead to accidents and seri­ ous 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 .
(D 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
for at idle for approximately two minutes be­
fore 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 diesel particulate
filter: The emissions control system is heat­
ed through the regeneration process, even if
the engine has not reached its operating
temperature yet .
