Both the Carnival and Pacifica have rear cross-traffic warning, but the Carnival has Rear Cross-Traffic Collision-Avoidance Assist (automatically applies the brakes) to better prevent a collision when backing near traffic. The Pacifica’s Rear Cross Path Detection doesn’t automatically brake.
The Carnival’s driver alert monitor detects an inattentive driver then sounds a warning and suggests a break. According to the NHTSA, drivers who fall asleep cause about 100,000 crashes and 1500 deaths a year. The Pacifica doesn’t offer a driver alert monitor.
Both the Carnival and the Pacifica have standard driver and passenger frontal airbags, front side-impact airbags, driver knee airbags, side-impact head airbags, front seatbelt pretensioners, front wheel drive, height adjustable front shoulder belts, four-wheel antilock brakes, traction control, electronic stability systems to prevent skidding, crash mitigating brakes, daytime running lights, lane departure warning systems, blind spot warning systems, rearview cameras, rear cross-path warning and available around view monitors.
For its top level performance in IIHS driver and passenger-side small overlap frontal, moderate overlap frontal, side impact, roof strength and head restraint tests, its standard front crash prevention system, and its headlight’s “Good” rating, the Insurance Institute for Highway Safety grants the Carnival its highest rating: “Top Safety Pick Plus” for 2019, a rating granted to only 137 vehicles tested by the IIHS. The Pacifica is only a standard “Top Safety Pick” for 2019.
