-If electrolyte fluid enters the eyes, flush
them thoroughly with a large amount of
clean water for at least 15 minutes and then
seek medical attention .
- If electrolyte fluid comes into contact with
the skin, flush the affected area with clean
water for at least 15 minutes and then clean
with soap and water and seek medical at­
tention. Clean affected clothing and shoes
thoroughly before wearing again .
- If the fluid was swallowed and the person is
conscious, flush the mouth with water for at
least 15 minutes. Do not induce vomiting
unless this is recommended by medical pro­
fessionals. Seek medical attenti .on immedi­
ately.
(D Note
If the glass on an automatic dimming mirror
breaks, electrolyte can leak out . This liquid
damages plastic surfaces and paint. Clean
this liquid as quickly as possible, for example
with a wet sponge .
@ Tips
-If the light reaching the rearview mirror is
obstructed, the automatic dimming mirror
will not function correctly,
- The automatic dimming mirrors do not dim
when the interior lighting is turned on or

switch on once the vehicle speed exceeds approx­ imately 2 mph (4 km/h) and it is ra ining. The
higher the sensitivity of the rain sensor that is set
(switch @ to the right), the earlier the wind­
shield wipers react to moisture on the wind ­
sh ield . You can deactivate the rain sensor mode
in the Infota inment system, which switches the
intermittent mode on. To do th is, select:

C leaning the headlights*. The headlight washer
system* operates only when the low beam head­ lights are sw itched on . If you move the lever into
position @, the headlights will be cleaned at
fixed intervals.
A WARNING
- 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
Light s and Vision
c::> page 58, Changing windshield wiper
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
w iper lever to any position.
- Wor n or dirty w indshie ld w iper blades resu lt
in st reaking. T his can affect the rain senso r
function. Check your windshield wiper
blades reg ularly.
- The washer fluid nozz les for the windshield
washer system are heated a t low tempera­
tures when the ignition is on .
- Whe n stopping tempo rar ily, such as at a
t raffic lig ht, the speed of the windshield
wipers automatically reduces by one level.
Cleaning windshield wiper blades
Clean the wiper b lades when you see wiper
streaks. Use a soft cloth and a g lass cleaner.

(D Note
-Only fold the windshield wipers away when
they are in the service position. Otherwise,
you could damage the paint on the hood or
the windshield wiper motor.
- You should not move your vehicle or operate the windshield wiper lever when the wiper
arms are folded away from the windshield.
The windshield wipers would move back in­
to their original position and could damage
the hood and windshield.
- To help prevent damage to the wiper sys­
tem, always loosen blades which are frozen
to the windshield before operating the wip­
ers.
- To help prevent damage to the wiper
blades, do not use gasoline, kerosene, paint
thinner, or other solvents on or near the
wiper blades.
- To help prevent damage to the wiper arms
or other components, do not attempt to
move the wipers by hand.
{l) Tips
-You can also use the service position, for ex­
ample, if you want to protect the windshield
from icing by using a cover.
- You cannot activate the service position
when the hood is open.

A WARNING
To reduce the risk to yourself and other dr iv­
ers, calibrate the compass in an area where
t here is no traffic .

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 .
