Driving and Operating 239
ACC may occasionally provide an alert and/
or braking that is considered unnecessary.
It could respond to vehicles in different
lanes, signs, guardrails, and other stationary
objects when entering or exiting a curve.
This is normal operation. The vehicle does
not need service.
Other Vehicle Lane Changes
ACC will not detect a vehicle ahead until it
is completely in the lane. The brakes may
need to be manually applied.
Objects Not Directly in Front of Your Vehicle
The detection of objects in front of the
vehicle may not be possible if:
.The vehicle or object ahead is not within
your lane.
.The vehicle ahead is shifted, not centered,
or is shifted to one side of the lane.Driving in Narrow Lanes
Vehicles in adjacent traffic lanes or roadside
objects may be incorrectly detected when
located along the roadway.
Do Not Use ACC on Hills and When Towing a
Trailer
Do not use ACC when driving on steep hills
or when towing a trailer. ACC will not detect
a vehicle in the lane while driving on steep
hills. The driver will often need to take over
acceleration and braking on steep hills,
especially when towing a trailer. If the
brakes are applied, the ACC disengages.
Disengaging ACC
There are three ways to disengage ACC:
.Step lightly on the brake pedal.
.Press*.
.PressJ.Erasing Speed Memory
The cruise control set speed is erased from
memory if
Jis pressed or if the ignition is
turned off.
Weather Conditions Affecting ACC
System operation may be limited under
snow, heavy rain, or road spray conditions.
Accessory Installations and Vehicle
Modifications
Do not install or place any object around
the front camera windshield area that would
obstruct the front camera view.
Do not install objects on top of the vehicle
that overhang and obstruct the front
camera, such as a canoe, kayak, or other
items that can be transported on a roof rack
system. See Roof Rack System 089.
Do not modify the hood, headlamps, or fog
lamps, as this may limit the camera’s ability
to detect an object.

Vehicle Care 343
Caution (Continued)
.Do not use scented or gel-type hand
sanitizers. If hand sanitizer comes in
contact with interior surfaces of the
vehicle, blot immediately and clean
with a soft cloth dampened with a
mild soap and water solution.
Interior Glass
To clean, use a microfiber cloth fabric
dampened with water. Wipe droplets left
behind with a clean dry cloth. If necessary,
use a commercial glass cleaner after
cleaning with plain water.
Caution
To prevent scratching, never use abrasive
cleaners on automotive glass. Abrasive
cleaners or aggressive cleaning may
damage the rear window defogger.
Cleaning the windshield with water during
the first three to six months of ownership
will reduce tendency to fog.
Speaker Covers
Vacuum around a speaker cover gently, so
that the speaker will not be damaged. Clean
spots with water and mild soap.
Coated Moldings
Coated moldings should be cleaned.
.When lightly soiled, wipe with a sponge
or soft, lint-free cloth dampened with
water.
.When heavily soiled, use warm soapy
water.
Vinyl/Rubber
If equipped with vinyl floor and rubber floor
mats, use a soft cloth and/or brush
dampened with water to remove dust and
loose dirt. For more thorough cleaning, use
a mild soap and water solution.
{Warning
Do not use cleaners that contain silicone,
wax-based products, or cleaners that
increase gloss on vinyl/rubber floor and
mats. These cleaners can permanently
change the appearance and feel of the
vinyl/rubber and can make the floor
slippery. Your foot could slip while
operating the vehicle, and you could lose
control, resulting in a crash. You or
others could be injured.
Fabric/Carpet/Suede
Start by vacuuming the surface using a soft
brush attachment. If a rotating vacuum
brush attachment is being used, only use it
on the floor carpet. Before cleaning, gently
remove as much of the soil as possible:
.Gently blot liquids with a paper towel.
Continue blotting until no more soil can
be removed.
.For solid soils, remove as much as
possible prior to vacuuming.
