In addition, beeps will sound, or the driver seat will pulse. See Assistance Systems for Parking or Backing 0 205.

Parking Assist If equipped, Rear Parking Assist (RPA) uses sensors on the rear bumper to assist with parking and

avoiding objects while in R (Reverse). It operates at speeds less than 8 km/h (5 mph). RPA may display a warning triangle on the Rear Vision Camera screen and/or a graphic on the instrument cluster to provide the object distance. In addition, multiple beeps may occur if very close to an object. See Assistance Systems for Parking or Backing 0 205.

eAssist Features

eAssist® Overview If the vehicle has eAssist, there are several additional features that contribute to increased efficiency. Vehicles with eAssist have an automatic engine start/stop feature. This feature saves fuel by shutting the engine off when the vehicle is stopped. When the engine shuts off automatically, all the accessories will continue to operate normally. In very hot or cold conditions, the engine may not shut off. See Starting the Engine 0 177. There are two air conditioning settings available. The comfort setting maximizes cabin comfort. The eco setting maximizes efficiency allowing more frequent, and longer engine stops than the comfort setting. See Dual Automatic Climate Control System 0 157.

This vehicle has a Hill Start Assist (HSA) feature, which may be useful when the vehicle is stopped on a grade. See Hill Start Assist (HSA) 0 192. Vehicles with eAssist include an AUTO STOP indicator on the tachometer. See Instrument Cluster 0 106. The eAssist system uses a high voltage battery, which is cooled with air drawn from the vehicle interior.

The cold air intake for the battery is located behind the rear seat, on the filler panel. Do not cover the intake. See Battery - North America 0 250.

High Voltage Safety Information Vehicles with eAssist have a standard 12-volt battery and a high voltage battery. Only a trained service technician with the proper knowledge and tools should inspect, test, or replace the high voltage battery. See your dealer if the high voltage battery needs service. In emergency situations, first responders can cut the two clearly labeled cut points in the engine compartment to disable the high voltage battery and air bag systems — do not cut the high voltage cable.

Automatic Engine Start/ Stop Feature Vehicles with eAssist have an automatic engine start/stop feature. After the engine is started and has reached operating temperature, the auto stop feature may cause the engine to turn off when the brake pedal is applied and the vehicle comes to a complete stop. When the brake pedal is released, or the

accelerator pedal is applied, the engine will restart. The engine will continue to run until the next auto stop. To restart the engine during the auto stop, release the brake pedal or press the accelerator pedal. The engine starts immediately. The vehicle continues to run until the next stop. AUTO STOP on the tachometer signifies that the engine is in auto stop mode. See Tachometer 0 109
for more information. A chime will sound when the driver door is opened while in auto stop mode. Remember to shift to P (Park) and turn the ignition to LOCK/OFF before exiting the vehicle. See Starting the Engine 0 177.

Regenerative Braking Regenerative braking takes some of the energy from the moving vehicle and turns it into electrical energy. This energy is then stored in the vehicle's high voltage battery system, contributing to increased fuel efficiency.

The system works whenever the accelerator pedal is released, and increases the energy captured as more brake pedal is applied.

Battery This vehicle has a standard 12-volt battery. Refer to the replacement number on the original battery label when a new standard 12-volt battery is needed. Vehicles with eAssist also have a high voltage battery. Only a trained service technician with the proper knowledge and tools should inspect, test, or replace the high voltage battery. See your dealer if the high voltage battery needs service. See Battery - North America 0 250.

Service Never try to do your own service on eAssist components. You can be injured and the vehicle can be damaged if you try to do your own service work. Service and repair of these high voltage components should only be performed by a trained service technician with the

See Traction Control/Electronic Stability Control 0 192.

Tire Pressure Monitor This vehicle may have a Tire Pressure Monitor System (TPMS).

The low tire pressure warning light alerts to a significant loss in pressure of one of the vehicle's tires. If the warning light comes on, stop as soon as possible and inflate the tires to the recommended pressure shown on the Tire and

Loading Information label. See Vehicle Load Limits 0 171. The warning light will remain on until the tire pressure is corrected. The low tire pressure warning light may come on in cool weather when the vehicle is first started, and then turn off as the vehicle is driven. This may be an early indicator that the tire pressures are getting low and the tires need to be inflated to the proper pressure. The TPMS does not replace normal monthly tire maintenance. Maintain the correct tire pressures. See Tire Pressure Monitor System 0 274.

Engine Oil Life System The engine oil life system calculates engine oil life based on vehicle use and displays the CHANGE ENGINE OIL SOON message when it is time to change the engine oil and filter. The oil life system should be reset to 100% only following an oil change.
