Brake System

Detail

When you depress the brake pedal, you may hear a whirring sound from the engine compartment. This is because the brake system is in operation, and it is normal.

Parking Brake

Use the parking brake to keep the vehicle stationary when parked. When the parking brake is applied, you can manually or automatically release it.

Detail

You may hear the electric parking brake system motor operating from the rear wheel area when you apply or release the parking brake. This is normal.

The brake pedal may slightly move due to the electric parking brake system operation when you apply or release the parking brake. This is normal.

You cannot apply or release the parking brake if the 12-volt battery goes dead.

If the 12-Volt Battery Is Dead

If you pull up and hold the electric parking brake switch while driving, the brakes on all four wheels are applied by the electric servo brake system until the vehicle comes to a stop. The electric parking brake then applies, and the switch should be released.

In the following situations, the parking brake automatically operates.

• When the vehicle stops more than 10 minutes while ACC with Low Speed Follow is activated.
• When the driver’s seat belt is unfastened while your vehicle is stopped automatically by ACC with Low Speed Follow.
• When the power system is turned off, while ACC with Low Speed Follow is activated.
• When the vehicle stops with the automatic brake hold system activated for more than 10 minutes.
• When the driver’s seat belt is unfastened while your vehicle is stopped and brake hold is applied.
• When the power system is turned off, while brake hold system is applied.
• When there is a problem with the brake hold system while brake hold is applied.

If the parking brake cannot be released automatically, release it manually.

When the vehicle is traveling uphill, the accelerator pedal may need to be pressed farther to automatically release the electric parking brake.

The parking brake cannot be released automatically while the following indicators are on:

• Malfunction indicator lamp
• Transmission system indicator

The parking brake may not be released automatically while the following indicators are on:

• Parking brake and brake system indicator (amber)
• VSA^® system indicator
• ABS indicator
• Supplemental restraint system indicator

In cold climates, the parking brake may freeze in place if applied.
When parking the vehicle, chock the wheels and make sure the automatic parking brake feature is deactivated.
Also, when putting your vehicle through a conveyor-type car wash or when having your vehicle towed, deactivate the automatic parking brake feature and leave the parking brake released.

Automatic parking brake feature operation

If the automatic parking brake feature has been activated:

• The parking brake is applied automatically when you set the power mode to VEHICLE OFF.
• To confirm that the parking brake is applied, check if the parking brake and brake system indicator (red) is on.
  

  Activating and deactivating the automatic parking brake feature

To release automatically

Depressing the accelerator pedal releases the parking brake.
Use the accelerator pedal to release the parking brake when you are starting the vehicle facing uphill, or in a traffic jam.

You can release the parking brake automatically when:

• You are wearing the driver’s seat belt.
• The power system is on.
• The transmission is not in P or N.

Activating and deactivating the automatic parking brake feature

With the power mode is in ON, carry out the following steps to either activate or deactivate the automatic parking brake feature.

1. Put the transmission into P.
2. Without depressing the brake pedal, pull up and release the electric parking brake switch.
   • Check that the parking brake and brake system indicator (red) has come on.
3. Pull up and hold the electric parking brake switch. When you hear a beeping sound, release the switch and within three seconds pull up and hold the switch again.
4. When you hear a sound indicating that the procedure is completed, release the switch.
   • Two beeps indicates that the feature has been activated.
   • One beep indicates that the feature has been deactivated.
   • When you have completed activating the feature, the parking brake will remain applied after you turn the power system off.
   • To confirm that the parking brake is applied, check if the parking brake and brake system indicator (red) is on.

If you need to temporarily deactivate the feature while putting your vehicle through a conveyor type car wash or when having your vehicle towed. You can follow the procedure explained below.

1. Depress the brake pedal and bring the vehicle to a stop.
2. Set the power mode to VEHICLE OFF and then within two seconds push down the electric parking brake switch.
   • Activation and deactivation settings for the feature will not be affected.
   • Before temporarily deactivating the feature, make sure to first turn off both Adaptive Cruise Control (ACC) with Low Speed Follow and the automatic brake hold system.
   • To confirm that the parking brake is applied, check if the parking brake and brake system indicator (red) is on.

Foot Brake

Your vehicle is equipped with disc brakes at all four wheels. The brake assist system increases the stopping force when you depress the brake pedal hard in an emergency situation. The anti-lock brake system (ABS) helps you retain steering control when braking very hard.

Detail

Check the brakes after driving through deep water, or if there is a buildup of road surface water. If necessary, dry the brakes by lightly depressing the pedal several times.

If you hear a continuous metallic friction sound when applying the brakes, this is caused by the brake wear indicator rubbing on the brake rotor and indicates that the brake pads need to be replaced. Have the vehicle checked by a dealer. If you hear only an occasional squeak or squeal when you initially apply the brake pedal, this may be normal and caused by high frequency vibration of the brake pads against the rotating brake disc.

Applying constant pressure to the brakes while going down a long hill can cause the brakes to heat up, resulting in a loss of stopping power.
Therefore, when descending a long hill, release the accelerator pedal and allow regenerative braking to slow the vehicle down.
To adjust the rate of deceleration, use the deceleration paddle selector.
When the high voltage battery has fully recharged, regenerative braking may not be possible.

Do not rest your foot on the brake pedal while driving, as it will lightly apply the brakes and cause them to lose effectiveness over time and reduce pad life. It will also confuse drivers behind you.

Automatic Brake Hold

Keeps the brake applied after releasing the brake pedal until the accelerator pedal is pressed. You can use this system while the vehicle is temporarily stopped, like at traffic lights and in heavy traffic.

WARNING

Activating the automatic brake hold system on steep hills or slippery roads may still allow the vehicle to move if you remove your foot from the brake pedal.

If a vehicle unexpectedly moves, it may cause a crash resulting in serious injury or death.

Never activate the automatic brake hold system or rely on it to keep a vehicle from moving when stopped on a steep hill or slippery roads.

WARNING

Using the automatic brake hold system to park the vehicle may result in the vehicle unexpectedly moving.

If a vehicle moves unexpectedly, it may cause a crash, resulting in serious injury or death.

Never leave the vehicle when braking is temporarily kept by automatic brake hold and always park the vehicle by putting the transmission in P and applying the parking brake.

WARNING

When using the automatic brake hold, keep your foot on the brake pedal until the automatic brake hold indicator comes on.

If the vehicle unexpectedly moves, it may cause a crash resulting in serious injury or death.
Release your foot from the brake pedal after the automatic brake hold indicator comes on.

Detail

While the system is activated, you can turn the power system off or park the vehicle through the same procedure as you normally do.

When Stopped

You may hear an operating noise if the vehicle moves while the automatic brake hold system is in operation.

Turning on the system

Activating the system

Canceling the system

The system automatically cancels when:

• You engage the parking brake.
• You depress the brake pedal and put the transmission into P or R.

The system automatically cancels and the parking brake is applied when:

• Braking is kept for more than 10 minutes.
• The driver’s seat belt is unfastened.
• The power system is turned off.
• There is a problem with automatic brake hold system.

Turning off the automatic brake hold system

Detail

Make sure to turn off the automatic brake hold system before using an automated car wash.

If you turn the power system off or unfasten the driver’s seat belt while the automatic brake hold system is on, the automatic brake hold system will automatically turn off. In this case, when the driver’s seat belt is fastened and the power system is turned back on, the automatic brake hold system will turn on without needing to press the automatic brake hold button.
