• Always check that the wiper blades are not fro zen to the glass
before you turn the wipers on. Loosen a wiper blade which is frozen
in place before operating the wipers to prevent damage to the wiper
blade or the wiper motor.
• Do not use the wipers to clea r a frosted window . Using the
wipers as a convenient ice scraper will destroy the wiper blades.
• Before you take your v ehicl e to an automatic car wash, make sure
you have the windshield wiper system switched off (lever in position
Ol, otherwise the windshield wiper sys tem could get damaged in the
car wash if it should suddenly come on.
[ i] Tips
• The rain sensor is part of the interval wiping system . Turning off
the ignition will also deactivate the rain sensor . To reactivate the
sensor, switch off the interval wiping function, then switch it back
on again.
• Worn or dirty windshield wiper blades cause smearing which
can affect the operation of the rain sensor. Check the condition of
your windshield wiper blades regularly.
• Make sure the washer fluid reservoir in the engine compartment
is topped off before going on a long trip. Look up~
page 316for
checking and filling the washer container .•

The selector lever must be in Nor P. If one of the driving positions
is engaged a safety switch will prevent the engine from being
started. See also
=:> page 117.
Before you move the selector lever from the
P position, you must
always apply the brake pedal before and while depressing the
button in the handle of the selector lever .
& WARNING
• Unintended vehicle movement can cause serious injury .
- When the selector lever is in a driving position, the vehicle
may creep, even at idle speed . Therefore do not release the
parking brake or foot brake until you are ready to move,
because power is transmitted to the wheels as soon as a
driving position is engaged.
- Do not accelerate while selecting a driving position. At this
time the engine must be at idle speed so that undue stress is
not placed on the clutches in the transmission.
- Remember: -even when stopped briefly with the automatic
transmission in "D", "S" or "R", engine power is being trans­
mitted to the wheels. Your vehicle could "creep" forward or
backward. When stopped, keep the brake pedal fully depressed
and use the parking brake if necessary to keep the vehicle from
rolling.
• If the selector lever is unintentionally moved into N while you
are driving, take your foot off the accelerator pedal and wait for
the engine to return to idle speed before selecting a driving posi­
tion .
• Never shift into "R" or "P" when the vehicle is in motion.
• Never get out of the driver's seat when the engine is running .
• If you must get out of the vehicle, move the selector lever
securely into the P position and apply the parking brake firmly.
• If the engine must remain running , never have any driving posi­
tion engaged when checking under the hood. Make sure the
selector lever has securely engaged and is locked in "P" with the
& WARNING (continued)

Otherwise, any increase in engine speed may set the vehicle in
motion, even with the parking brake applied. •
