Make sure that the open luggage compart­
ment lid and the ti lting/sliding sunroof* or
panorama glass roof* do not come into con­
tact with objects on the roof.
@ For the sake of the environment
Your veh icle will use more fuel due to the in­
creased wind res istance. So remove the roof

Climate control system
Description
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 vehicle, ventilation can he lp to speed
up the cooling process.
I n all heating mode f unctions except for
defrost,
the blower only switches to a higher speed once
the engine coolant has reached a sufficient tem­
perature .
Pollutant filt er
The po llutant filter removes poll utants such as
dust and pollen from the a ir .
Ke y recognit ion
The climate control settings are automatically
stored and assigned to the remote contro l key
that is in use .

® For the sake of the environment
-If you would like to reduce fuel consump­
t ion, sw itch the air conditioning
off. This
will also reduce emissions.
- In veh icles 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 windshie ld must be free of ice,
snow or leaves.
- Condensation from the cooling system can
dr ip and form a pudd le of water under the
vehicle . This is norma l and does not mean
there is a leak.
- The energy management system may tem­ porarily switch
off certain functions, such as
the seat heating* o r rear window defogger.
T hese systems are ava ilable again as soon
as the ene rgy 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 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

.. Only drive in terrain that is suitable for the ve ­
hicle and your driving ability. Never take any
unnecessary risks!
.. Drive slowly and carefully.
.. Pay attention to the ground cl eara nce of your
vehicle .
.. Activate the o ffroad mod e as needed
~page 147 .
.,. Use the hill de sce nt ass is t when dr iving down
steep h ills
¢page 148.
Difficult ter rain
When driving in unfamiliar areas and offroad,
drive slowly and keep on the watch for unexpect­
ed obstacles (such as potholes, rocks, tree
stumps, etc.).
To prevent the veh icle from bottoming out and to
reduce the risk of underbody damage, you sho uld
d rive across uneven ground on only one side of
the veh icle so that only two of your wheels cross
the uneve n are a, instead of driving across the
center of the uneven area with a ll four wheels .
Drive quick ly through sandy or marshy off-road
sections and do not stop, if at all possible.

Automatic transmission
Introduction
Applies to: vehicles with automatic transm issions
The automat ic transmission is controlled elec­
tronically. The transmission shifts up o r down au­
tomatically depend ing on which drive program is
se lected .
When a
moderate drivi ng style is used, the
transmission selects the most economical driving
mode. The transmiss ion upshifts at a lower RPM
and downshifts at a higher RPM to improve fuel
efficiency .
The transm ission switches to a sporty mode after
a kick-down or when the driver uses a
s po rty
d rivi ng style
character ized by quick accelerator
pedal movements, heavy acceleration, frequent
D rivi ng
changes in sp eed and traveling at the maximum
speed.
If des ired, t he d river can also se lect the gea rs
manually (tiptronic mo de) ¢ page 94 .
S tronic transmission
The S tron ic is a dual-clutch transmission . Power
is transferred using two clutches that work inde­
pendent ly from one another. They rep lace the
torque conve rter used in convent io nal automatic
transm issions and allow the vehicle to accelerate
without a noticeable interruption in traction.
tiptronic transmission
In th e tiptronic transmission, power is t ransfer­
red by a torque conve rter.
Selecting a selector lever position
Applies to: vehicles with automatic transmissions
Fig. 98 Center console : se lector lever
The current se lector lever position is shown next
to the se lector lever
c::> fig. 98 . The current se lec­
tor leve r position is a lso shown in the instr ument

Predictive efficiency
assist
Descript ion
Applies to: vehicles with predictive efficiency assist
General information
The pred ictive eff ic iency assist helps the driver to
d rive w ith anticipation and therefore helps to
save fuel. The system accesses predictive trip da­
ta (including speed limits, inclines and the radius
of curves) from the navigation system*. Informa­
tion from the camera-based traff ic sign recogni­
tion* is also applied to recognize traffic signs
r;;:;ipage 104.
The messages displayed depend on the naviga­
tion data* being up-to-date and the correct iden­
tification by the traffic sign recognition*.
When adaptive cruise contro l* is switched off,
the predictive efficiency assist only provides noti­
fications without controlled interventions. When
adaptive cruise control* is switched on, the sys­
tem responds to upcoming situations automati­
cally.
Vehicles with adaptive cruise control*
Refer to predictive control c> page 115.
Indicator in the instrument cluster display
Predictive messages appea r in the instr ument
cluster display to show the driver the appropriate
time to coast when a situation ahead requires
you to drive at a lower speed.
The messages are only shown if the cr uise control
system* or adaptive cruise control* is switched
off .
Assistance systems
An additional indicator appears in the head-up
display* .
Symbol Meaning
Remove your foot from the acceler -
"
ator pedal to slow down, because
there is a situation ahead that re- quires a lower speed.
If you see Driver assistance in the instrument
cluster disp lay, the following symbols will indi­
cate which situation the system is currently re­
acting to.

.&, WARNING ~ -
Pay attention to traffic and the area around
your vehicle when the efficiency assist is
switched on. The driver is always respons ible
for assessing the traffic situation.
(D Tips
- The wording of the message may vary de­
pending on the driving mode set in drive se­
lect* c> page 133 and the current selector
lever position (automatic transmiss ion*).
No messages are displayed when in the S
selector lever position or in
Dynamic mode.
- When a route is planned using the naviga­
tion system*, then the message feed is based on this route. Without route guid­
ance, the system uses an assumed route fo r
the message feed.
- There will not be a message for every s itua­
tion ahead, for example if there is not
enough distance remaining to react to the
situation.
