The Sienna Limited Premium FWD’s optional pre-crash front seatbelts will tighten automatically in the event the vehicle detects an impending crash, improving protection against injury significantly. The ProMaster City Wagon doesn’t offer pre-crash pretensioners.
The Sienna has standard Active Headrests, which use a specially designed headrest to protect the driver and front passenger from whiplash. During a rear-end collision, the Active Headrests system moves the headrests forward to prevent neck and spine injuries. The ProMaster City Wagon doesn’t offer a whiplash protection system.
The Sienna has standard Pre-Collision System, which use forward mounted sensors to warn the driver of a possible collision ahead. If the driver doesn’t react and the system determines a collision is imminent, it automatically applies the brakes at full-force in order to reduce the force of the crash or avoid it altogether. The ProMaster City Wagon doesn't offer collision warning or crash mitigation brakes.
The Sienna offers all-wheel drive to maximize traction under poor conditions, especially in ice and snow. The ProMaster City Wagon doesn’t offer all-wheel drive.
The Sienna’s lane departure warning system alerts a temporarily inattentive driver when the vehicle begins to leave its lane and gently nudges the vehicle back towards its lane. The ProMaster City Wagon doesn’t offer a lane departure warning system.
The Sienna Limited Premium has a standard Bird’s Eye View Monitor to allow the driver to see objects all around the vehicle on a screen. The ProMaster City Wagon only offers a rear monitor and rear parking sensors that beep or flash a light. That doesn’t help with obstacles to the front or sides.
To help make backing safer, the Sienna (except L)’s optional cross-path warning system uses wide-angle radar in the rear bumper to alert the driver to vehicles approaching from the side, helping the driver avoid collisions. The ProMaster City Wagon doesn’t offer a cross-path warning system.
The Sienna has standard Safety Connect™, which uses a global positioning satellite (GPS) receiver and a cellular system to help track down your vehicle if it’s stolen or send emergency personnel to the scene if any airbags deploy. The ProMaster City Wagon doesn’t offer a GPS response system, only a navigation computer with no live response for emergencies, so if you’re involved in an accident and you’re incapacitated help may not come as quickly.
Both the Sienna and the ProMaster City Wagon 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, plastic fuel tanks, four-wheel antilock brakes, traction control, electronic stability systems to prevent skidding, rearview cameras and available blind spot warning systems.

For better traction, the Sienna has larger tires than the ProMaster City Wagon (235/60R17 vs. 215/55R16).

The Sienna’s liftgate lifts up in one piece, completely out of the way of loading and unloading, while sheltering the cargo loading area. The ProMaster City Wagon’s two swing out doors impair rear visibility, need a lot of clearance, and can block loading in tight quarters.
To make loading and unloading groceries and cargo easier, especially for short adults, the Sienna (except L) offers an optional power liftgate, which opens and closes automatically by pressing a button. The ProMaster City Wagon doesn’t offer a power cargo door.
The Sienna’s standard towing capacity is much higher than the ProMaster City Wagon’s (3500 vs. 1867 pounds).
When two different drivers share the Sienna Limited, the memory seats and mirrors make it convenient for both. Each setting activates different, customized memories for the driver’s seat position and outside mirror angle. The ProMaster City Wagon doesn’t offer a memory system.
The Sienna Limited’s standard easy entry system glides the driver’s seat back when the door is unlocked or the ignition is switched off, making it easier for the driver to get in and out. The ProMaster City Wagon doesn’t offer an easy entry system.
The Sienna’s front and rear power windows all open or close fully with one touch of the switches, making it more convenient at drive-up windows and toll booths, or when talking with someone outside the car. The ProMaster City Wagon’s rear power window switches have to be held the entire time to open or close them fully.
The Smart Key System optional on the Sienna (except L) allows you to unlock the doors, cargo door and start the engine all without removing a key from pocket or purse. This eliminates searching for keys before loading groceries, getting in the vehicle in bad weather or making a hurried start to your trip. The Ram ProMaster City Wagon doesn’t offer an advanced key system.
The Sienna has a standard locking fuel door with a remote release located convenient to the driver. A locking fuel door helps prevent vandalism, such as sugar in the tank and fuel theft. The ProMaster City Wagon doesn’t offer a locking fuel door.
The Sienna’s standard variable intermittent wipers have an adjustable delay to allow the driver to choose a setting that best clears the windshield during light rain or mist. The ProMaster City Wagon’s fixed intermittent wipers only have one fixed delay setting, so the driver will have to manually switch them between slow and intermittent. The Sienna Limited Premium’s standard wipers adjust their speed and turn on and off automatically according to the amount of rainfall on the windshield.
To improve rear visibility by keeping the rear window clear, the Sienna has a standard rear wiper. A rear wiper costs extra on the ProMaster City Wagon.
The Sienna has a standard automatic headlight on/off feature. When the ignition is on, the headlights automatically turn on at dusk and off after dawn. The ProMaster City Wagon doesn’t offer automatic headlights.
While driving with high beams on, sensitive light sensors standard on the Sienna detect other vehicles which could be blinded and automatically switch to low beams. The ProMaster City Wagon doesn’t offer automatic dimming high beams.
When the Sienna Limited is put in reverse, both rearview mirrors tilt from their original position. This gives the driver a better view of the curb during parallel parking maneuvers. Shifting out of reverse puts the mirrors into their original positions. The ProMaster City Wagon’s mirrors don’t automatically adjust for backing.
The Sienna LE/SE/XLE/Limited’s standard rear and side view mirrors have an automatic dimming feature. These mirrors can be set to automatically darken quickly when headlights shine on them, keeping following vehicles from blinding or distracting the driver. The ProMaster City Wagon doesn’t offer the luxury of automatic dimming mirrors.
On extremely cold winter days, the Sienna Limited’s standard heated steering wheel provides comfort, allowing the driver to steer safely and comfortably before the vehicle heater warms up. The ProMaster City Wagon doesn’t offer a heated steering wheel.
The Sienna’s standard dual zone air conditioning allows the driver and front passenger to choose two completely different temperatures so people with different temperature preferences won’t have to compromise. This makes both the driver and front passenger as comfortable as possible. The ProMaster City Wagon doesn’t offer dual zone air conditioning.
The Sienna’s standard automatic temperature control maintains the temperature you set, automatically controlling fan speed, vents and temperature to maintain a consistent, comfortable environment. The ProMaster City Wagon doesn’t offer automatic air conditioning.
For greater rear passenger comfort, the Sienna has standard rear a/c vents to keep rear occupants more comfortable. The ProMaster City Wagon doesn’t offer rear vents.
To keep a safe, consistent following distance, the Sienna has a standard Dynamic Radar Cruise Control, which alters the speed of the vehicle without driver intervention. This allows the driver to use cruise control more safely without constantly having to disengage it when approaching slower traffic. The ProMaster City Wagon doesn’t offer an adaptive cruise control.
The Sienna Premium has a 115-volt a/c outlet on the center console, allowing you to recharge a laptop or run small household appliances without special adapters that can break or get misplaced. The ProMaster City Wagon doesn’t offer a house-current electrical outlet.
The Sienna will cost the buyer less in the long run because of its superior resale value. The IntelliChoice estimates that the Sienna will retain 45.43% to 52.8% of its original price after five years, while the ProMaster City Wagon only retains 42.69% to 43.24%.
