& WARNING
• Wiper blade s are cru cial fo r safe driving ! O nly when they are in
good cond it ion are they able to clear the window s properly to
p ro vi de un comp romi sed vis ibility . Worn or damaged wiper blade s
are a safety hazard
=> page 8 7, "In stalling new w ipe r blades "!
• The rain sen sor is onl y de signed to a ssis t and support the
driver. It remain s ent irely the driver' s re spon sibility to monitor
o ut side weather condit ion s a nd to manually acti vate the wipers a s
soon a s rain or drizzle reduces vi sibility through the wind shield .
• The wind shield mu st not be treat ed w ith water -repellent mate ­
rials. They can increase glare under poor visibility conditions such
a s w etne ss, darknes s, or when the sun i s lo w on t he horizon . In
addition , they can cause the windshield wipers to chatter .
0 Note
In freezing or near freezing conditions :
• Always check that the wiper blades are not frozen to the g lass
before you turn the wipers on. Loosen a wiper b lade which is frozen
in place before operating the wipers to prevent damage to the wiper
b lade or the wipe r motor.
• Do not use the wipers to clear a frosted window . Using the
wipe rs as a convenient ice scraper wil l destroy the wiper blades .
• Before you take your vehicle to an automatic car wash , make sure
you have the wi ndshield w iper system switched off (lever in position
0), otherwise the windshield wiper system could get damaged in the
car wash if it should suddenly come on .
[ i ] Tips
• The rain sensor is part of the interva l wiping system . Turning off
the ignition will also deactivate the rain sensor. To reactivate the sensor, switch off the interva l wiping function, then switch it back
on aga in. • I
f you switch off the ignition with the windshield wiper lever sti ll
in the interva l wipe position and then come back a while late r and
drive off, the rain sensor will reactivate itself after the vehicle speed
has exceeded 4 mph (6 km/h) .
• Worn or dirty windshield wiper b lades cause smearing which
can affect the operation of the rain sensor . Check the condition of
your windshield wiper b lades regularly .
• Make sure the washer fluid reservoir in the engine co mpartment
is topped off before going on a long trip. Look up=>
page 266 for
checking and f illing the washer container .•

The washer jets extend forward out of the front bumper driven by
water pressure to s pray the front headlights with water .
You should inspec t the head lights regu larly (for examp le when refu ­
e ling) and c lean off any so lid dirt or insects from the lenses .
To ensure the sys tem works proper ly in winter, keep the washer jets
free of snow and
remove any ice using a de -icing spray .•

& WARNING
The glass of the inside rearview mirror is layered and contains an
electrolyte to achieve its properties. Be aware of liquid electrolyte
leaking from a broken mirror glass. This liquid can cause irritation
to skin, eyes, and respiratory system. If you get electrolyte in your
eyes or on your skin, immediately rinse with plenty of water. If irri­
tation persists, seek medical attention.
0 Note
Liquid electrolyte leaked from a broken mirror glass will damage any
plastic surfaces it comes in contact with. Clean up spilled electrolyte
immediately with clear water and a sponge.
[ i] Tips
• If you switch off the automatic dimming function on the inside
mirror, automatic dimming of the outside mirrors will likewise be
disabled.
• Check to make sure there are no objects preventing light from
reaching the inside mirror.
• Do not attach any stickers to the windshield in front of the light
sensor, as this would interfere with the automatic operation of the
headlights and the automatic dimming of the inside mirror.•
