Driving
Traffic Jam Assist
The traffic jam assist system uses a radar sensor mounted inside the front grille and
a camera mounted to the upper portion of the windshield to detect and monitor left
and right white (yellow) traffic lane lines as well as any vehicle ahead. Based on
inputs from the radar sensor and camera , the system adjusts the speed of your
vehicle to maintain a set interval between your vehicle and the one detected ahead.
It also applies steering torque to keep your vehicle in the center of the detected lane
when you are driving in heavy traffic.
■How Traffic Jam Assist works
If you are in heavy traffic and Adaptive Cruise Contro l with Low Speed Follow is
active, the traffic jam assist system, upon detecting the traf fic lane lines and a vehicle
ahead, will apply steering torque to help keep your vehicle in the center of the lane.
The system adjusts the speed of your vehicl e to maintain a set interval between your
vehicle and the one detected ahead.

3WARNING
Improper reliance on Traffic Jam Assist can
cause a crash resulting in injury or death.
Always maintain full control over your
vehicle even when this system is active. and
only use when on ex pressways or freeways.
Traffic Jam Assist is not an autonomous
driving system.
3WARNING
Failure to securely park vehicle when
stopped while Adaptive Cruise Control with
Low Speed Follow is active can allow the
vehicle to roll away, resulting in a crash
causing injury or death.
Never stop the vehicle and exit it without
placing it in Park and setting the parking
brake.

uuWarranty Coverages u
Information
Replacement Battery Limited Warranty – provides prorated coverage for a
replacement battery purchased from your dealer.
Replacement Muffler Life time Limited Warranty – provides coverage for as
long as the purchaser of the muffler owns the vehicle.
Restrictions and exclusions apply to a ll these warranties. Please read the Acura
warranty information booklet that came with your vehicle for precise information on
warranty coverages. Your vehi cle’s original tires are covered by their manufacturer.
Tire warranty information is in a separate booklet.
■Statement on Warranty Coverage for Aftermarket and Recycled Parts
The Magnuson-Moss Warranty Act, 15 U.S.C. s.2301 et seq., makes it illegal for
motor vehicle manufacturers to void a motor vehicle warranty or deny warranty
coverage solely because an aftermarket or re cycled part has been used to repair the
vehicle or someone other than the authoriz ed service provider performed service on
the vehicle.
This provision does not apply to a new motor vehicle purchased solely for
commercial or industrial use.
Under federal law, a manufacturer may deny warranty coverage and charge for repairs
to a vehicle if it is discovered that an aftermarket or recycled part installed on the
vehicle is defective or was in stalled incorrectly and caused damage to another part of
the vehicle otherwise co vered under warranty.
The Federal Trade Commission requires that a manufacturer demonstrate that an
aftermarket or recycled part or service performed by a person other than an
authorized service provider caused damage to another part of the vehicle otherwise
covered under warranty before denying warranty coverage.
Additionally, federal law allo ws a manufacturer to void a motor vehicle warranty or
deny warranty coverage if the manufacture r provides the article or service to
consumers free of charge under the warr anty or the manufacturer has secured a
waiver from the Federal Trade Commission.
