This vehicle is equipped with an
event data recorder (EDR). The
main purpose of an EDR is to
record, in certain crash or near
crash-like situations, such as an
air bag deployment or hitting a
road obstacle, data that will
assist in understanding how a
vehicle’s systems performed.
The EDR is designed to record
data related to vehicle dynamics
and safety systems for a short
period of time, typically 30 sec-
onds or less.
The EDR in this vehicle is
designed to record such data
as:
• How various systems in your vehicle were operating;
• Whether or not the driver and passenger safety belts were

6-1.Maintenance and care
Working from top to bottom,
liberally apply water to the
vehicle body, wheel wells and
underside of the vehicle to
remove any dirt and dust.
 Wash the vehicle body using
a sponge or soft cloth, such
as a chamois.
 For hard-to-remove marks,
use car wash soap and rinse
thoroughly with water.
 Wipe away any water.
 Wax the vehicle when the
waterproof coating deterio-
rates.
If water does not bead on a clean
surface, apply wax when the vehi-
cle body is cool.
■Automatic car washes
●Fold the mirrors before washing
the vehicle. Start washing from the
front of the vehicle. Make sure to
extend the mirrors before driving.
●Brushes used in automatic car
washes may scratch the vehicle
surface, parts (wheel, etc.) and
harm your vehicle’s paint.
●Vehicles with a rear spoiler: In cer-
tain automatic car washes, the rear spoiler may interfere with
machine operation. This may pre-
vent the vehicle from being
cleaned properly or result in dam-
age to the r
ear spoiler.
■High pressure car washes
As water may enter the cabin, do
not bring the nozzle tip near the
gaps around the doors or perimeter
of the windows, or spray these
areas continuously.
■When using a car wash (vehi-
cles with a smart key system)
If the door handle becomes wet
while the electronic key is within the
effective range, the door may lock
and unlock repeatedly. In that case,
follow the following correction pro-
cedures to wash the vehicle:
●Place the key in a position 6 ft. (2
m) or more separate from the
vehicle while the vehicle is being
washed. (Take care to ensure that
the key is not stolen.)
●Set the electronic key to bat-
tery-saving mode to disable the
smart key system. ( P.121)
■Wheels and wheel ornaments
●Remove any dirt immediately by
using a neutral detergent.
●Wash detergent off with water
immediately after use.
●To protect the paint from damage,
make sure to obs erve the follow-
ing precautions.
• Do not use acidic, alkaline or abrasive detergent
• Do not use hard brushes
• Do not use detergent on the
wheels when they are hot, such
as after driving or parking in hot
weather
■Brake pads and calipers
Rust may form if the vehicle is
parked with wet brake pads or disc
rotors, causing them to stick. Before
parking the vehicle after it is
washed, drive slo wly and apply the
brakes several times to dry the
