& WARNING
• Wiper blades are crucial for safe driving! Only when they are in
good condition are they able to clear the windows properly to
provide uncompromising visibilit y. Worn or damaged wiper blades
are a safety hazard
=> page 82 , "In stalling new wiper blade s"!
• The rain sensor is only designed to assist and support the
driver . It remains entirely the driver' s respon sibility to monitor
out side weather condit ions and to manually acti vate the wipers as
soon as rain or drizzle reduces visibility through the windshield.
• The windshield must not be treated with water-repellent mate­
rial s. They can increa se glare under poor visibility conditions such
as wetness , darkness , or when the sun is low on the horizon. In
addition , they can cau se the wind shield wipers to chatter.

General recommendations
Why is your seat adjustment so important?
The safety belts and the airbag system can only provide
maximum protection if the front seats are correctly
adjusted.
There are various ways of adjusting the front seats to provide safe
and comfortable support for the driver and the front passenger.
Adjust your seat properly so that :
• you can easily and quickly reach all the switches and controls in
the instrument panel
• your body is properly supported thus reducing physical stress
and fatigue
• the safety belts and airbag system can offer maximum protec ­
tion =>
page 220.
In the following sections , you will see exactly how you can best
adjust your seats.
There are special regulations and instructions for installing a child seat on the front passenger's seat. Always follow the information
regarding child safety provided in=>
page 245, "Child Safety".
L1}. WARNING
Incorrect seating position of the driver and all other passengers
can result in serious personal injury.
• Always keep your feet on the floor when the vehicle is in motion
- never put your feet on top of the instrument panel, out of the
window or on top of the seat cushion. This applies especially to
the passengers. If your seating position is incorrect, you increase
the risk of injury in the case of sudden braking or an accident. If
& WARNING (continued)
the airbag inflates and the seating position is incorrect, this could
result in personal injury or even death.
• It is important for both the driver and front passenger to keep
a distance of at least 10 inches (25 cm) between themselves and
the steering wheel and/or instrument panel. If you're sitting any closer than this, the airbag system cannot protect you properly. In
addition, the front seats and head restraints must be adjusted to
your body height so that they can give you maximum protection.
• Always try to keep as much distance as possible between your­
self and the steering wheel or instrument panel.
• Do not adjust the driver's or front passenger's seat while the
vehicle is moving. Your seat may move unexpectedly, causing
sudden loss of vehicle control and personal injury.
If you adjust
your seat while the vehicle is moving, you are out of position. •
Driver's seat
The correct seat position is important for safe and relaxed
driving.
We recommend that you adjust the driver's seat in the
following manner:
- Adjust the seat in fore and aft direction so that you can
easily push the pedals to the floor while keeping your
knees slightly bent=>
& in "Why is your seat adjustment
so important?".
Adjust the seatback so that when you sit with your back
against the seatback, you can still grasp the top of the
steering wheel. _..

serious personal injury.
• Always use suitable retaining straps and properly secure items
to the tie-downs in the luggage compartment to help prevent
items from shifting or flying forward.
• Never attach a child seat tether strap to a tie-down .•
