All weather lights
The front lights a re adjusted au toma tically so
that there is less g lare fo r the d river from his o r
her ow n lights , fo r example when roads are wet .
Automatic dynamic headlight range control*
Your vehicle is equipped with a headlight range
contro l system so that there is les s glare fo r on­
com ing t raff ic if the vehicle load changes . Th e
headlight range also adjusts automatically when
braking and accelerat ing.
Static cornering light *
The static co rnering light may be available de­
pend ing on veh icle equipment and it only works
whe n the light swi tc h is in the AUTO position. The
cornering light switches on automatica lly at
spe eds up to approximately 44 mph (70 km/h) at
spec ific steering wheel ang les and at speeds up
to approximate ly 25 mph (40 km/h) when you
turn on a turn signal. The a rea to the side of the
vehicle is illuminated better when turni ng.
_& WARNING
- Automatic headlights are only intended to
assis t the driver. They do not relieve the
d river of respo nsib ility to chec k the he ad­
lights and to t urn them on m anu ally based
on t he cur re nt ligh t and v is ib ility condi tions.
F or e xamp le, fog cannot be detected by t he
light sensors . So always switch on the low
beams under these weather condit ions and
when dr iv ing in the dark
~D.
- The rear fog lights sho uld only be turned on
in accordance w ith traffic regulations, to
prevent glare for traffic behind your vehicle.
- Always observe lega l regulat ions when us­
ing the lighting systems desc ribed.
(D Tips
- The lig ht sensor for the a utomat ic head ­
lights is located in the rearview mi rror
mount. Do not p lace any st ic kers in this area
on the w indshield.

justed
¢ page 52.

-If you turn off the ignition while the exterior
lights are on and open the door, a warning
tone sounds.
- In cool or damp weather, the inside of the
headlights , turn signals and tail lights can
fog over due to the temperature difference between the inside and outside. They will
clear shortly after switching them on. This
does not affect the service life of the light­
ing .

- T he rain sensor is only intended to assist the
driver. The driver may still be responsible
for manually switching the w ipers on based
on v is ibility conditions.
- The w indshie ld may not be treated with wa­
ter -repelling windshield coating agents. Un­
favorable conditions, s uch as wetness, dark­
ness or low sun, can result in increased
glare, which increases the risk of an acc i­
dent . Wiper blade chatter is also poss ible.
- Properly functioning windsh ield wiper
blades are required for a clear view and safe
dr iv ing to red uce the risk of an accident

blades.
@ Note
- If there is frost, make sure the windshield
wiper blades are not frozen to the wind­
shield. Switching on the windshield wipers
when the blades are frozen to the wind­
shield can damage the w iper blades.
- Prior to using a car wash, the windshield
wiper system must be sw itched off (lever in
position
0). This prevents the wipers from
switching on unintentionally and caus ing
damage to the windsh ield wiper system.
@ Tips
- The windshield wipers switch off when the
ign ition is switched off. You can activate the
w indshield wipers after the ignition is
switched back on by moving the w indshield

Driving
next traffic light is red . This produces an engine
braking effect, which helps to protect the brakes
and tires and reduces the emissions and fue l con ­
sumpt ion to zero (fuel shut-off during decelera­
t ion).
Shift effici ently
An effective way to save fuel is to upshift earlier.
Staying in a gear too long uses fue l unnecessari ­
ly .
P ress down o n the acce lerator peda l slowly and
avoid "kick -down".
Avoid full acceleration
You shou ld rare ly t rave l at the maximum vehicle
speed. High speeds cause a disp roportiona tely
h igh inc rease in fuel consump tion, emissions and
traffic no ise . Slower driving saves fuel.
Reduce idling time
The Start/Stop system* he lps to reduce the idling
time automatically. In vehicles witho ut the Start/
S top system* , it is efficient to swit ch the eng ine
off when stopped at r,;1ilro,;1d crossi ngs 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 engine.
It t akes a very long time in idle to war m the en ­
g ine up to opera ting tempera ture . Wea r and
emissions are especially high in the warm -up
p hase . Therefore, yo u should begin driving im ­
mediately after starting the engine. Avoid high
RPMs while do ing th is.
Have maintenance performed regularly
By having ma intenance performed regularly on
your vehicle, you can help 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 t raffic safety and long-term value but a l­
so impacts
fuel consumpt ion . A poorly main ­
tained engine can lead to f uel consumption that
is 10% higher than normal.
Avoid short trips
The engine and exhaust cleaning system m ust
reach the ir opt imal
operating temperature to ef­
fectively reduce consumption and em iss ions.
74
A cold engine uses a d isproportionately high
amount of fue l. The engine reaches operating
temperat ure and cons umption norma lizes on ly
after approximate ly
four ki lometers.
Check the tire pres sure
To save fue l, make sure the t ires are always in­
flated to the correct press ure
¢ page 32 7. The
fuel consumpt ion can increase by S% if the pres ­
s u re is only 0.5 bar too low. Due to the increased
roll ing resistance, low tire pressures w ill also
l ead to greater tire
wear and will affect dr iving
behavior.
Do not drive on
winter tires year-round, as this
will consume up to 10% more f uel.
Eliminate unnecessary we ight
Since eve ry kil og ram o f extra weight in creases
fuel consumption, a quick inspection of the lug­
gage compartment may be worth it to avoid un­
necessary we ight.
When no t be ing used, a roof rack sho uld be re ­
moved to decrease the wind resistance of the ve­
hicle . You will save approx imately
12% of your
fuel when at speeds from 62-75 mph (100-120 km/h).
Save energy
The eng ine drives the generator, which generates
electricity; the fuel consumption also inc reases
with the demand for e lectricity. Therefore, switch
e lectrical equ ipment off when you no longer
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* .
(D Note
Do not leave engine idling unattended after
starting . If warning lights shou ld come on to
i ndica te improper operation, they would go
unheeded . Extended idling also prod uces
h eat, w hic h could result i n overheating o r
o ther damage to the veh icle o r othe r prope r­
ty .
