Non-operational conditions of
back-up warning system
The back-up warning system may
not operate properly when:
1. Moisture is frozen to the sensor. (It
will operate normally when the
moisture has been cleared.)
2. The sensor is covered with foreign matter, such as snow or water, or
the sensor cover is blocked. (It will
operate normally when the materi-
al is removed or the sensor is no
longer blocked.)
3. Driving on uneven road surfaces. (unpaved roads, gravel, bumps,
gradient.)
4. Objects generating excessive noise (vehicle horns, loud motor-
cycle engines, or truck air brakes)
are within range of the sensor.
5. Heavy rain or water spray exists.
6. Wireless transmitters or mobile phones are within range of the
sensor.
7. The sensor is covered with snow.
8. Trailer towing. The detecting range may decrease
when:
1. The sensor is stained with foreign
matter such as snow or water.
(The sensing range will return to
normal when removed.)
2. Outside air temperature is extremely hot or cold.
The following objects may not be
recognized by the sensor:
1. Sharp or slim objects such as ropes, chains or small poles.
2. Objects which tend to absorb the sensor frequency such as clothes,
spongy material or snow.
3. Undetectable objects smaller than 1 m (40 in.) in height and narrower
than 14 cm (6 in.) in diameter.
back-up warning system pre-
cautions
The back-up warning system maynot sound sequentially depending
on the speed and shapes of the
objects detected.
The back-up warning system may malfunction if the vehicle bumper
height or sensor installation has
been modified or damaged. Any
non-factory installed equipment or
accessories may also interfere with
the sensor performance.
The sensor may not recognize objects less than 30 cm (11 in.)
from the sensor, or it may sense an
incorrect distance. Use caution.
When the sensor is frozen or stained with snow, dirt, or water, the sensor
may be inoperative until the stains
are removed using a soft cloth.
Do not push, scratch or strike the sensor. Sensor damage could occur.

Don't let your parking brake
freeze
Under some conditions your parking
brake can freeze in the engaged
position. This is most likely to hap-
pen when there is an accumulation
of snow or ice around or near the
rear brakes or if the brakes are wet.
If there is a risk the parking brake
may freeze, apply it only temporarily
while you put the shift lever in P
(automatic transaxle) and block the
rear wheels so the vehicle cannot
roll. Then release the parking brake.
Don't let ice and snow accu-
mulate underneath
Under some conditions, snow and
ice can build up under the fenders
and interfere with the steering. When
driving in severe winter conditions
where this may happen, you should
periodically check underneath the
car to be sure the movement of the
front wheels and the steering com-
ponents is not obstructed.
Carry emergency equipment
Depending on the severity of the
weather you should carry appropri-
ate emergency equipment. Some of
the items you may want to carry
include tow straps or chains, flash-
light, emergency flares, sand, a
shovel, jumper cables, a window
scraper, gloves, ground cloth, cover-
alls, a blanket, etc.
TRAILER TOWING
We do not recommend using this
vehicle for trailer towing.
