The Electronic Stability Control (ESC) system helps to stabilize the vehicle during cornering maneuvers.

ESC checks where you are steering and where the vehicle is actually going. ESC applies braking pressure to any one of the vehicles brakes and intervenes in the engine management system to assist the driver with keeping the vehicle on the intended path. It is not a substitute for safe driving practices. Always adjust your speed and driving to the road conditions.

WARNING

Never drive too fast for the road conditions or too quickly when cornering. The ESC system will not prevent accidents. Excessive speed in turns, abrupt maneuvers, and hydroplaning on wet surfaces can result in severe accidents.

ESC operation

ESC ON condition

When the ignition switch is in the ON position, the ESC and the ESC OFF indicator lights illuminate for approximately three seconds and goes off, then the ESC is turned on.

If this light stays on, your vehicle may have a malfunction with the ESC system. Have your vehicle checked by an authorized HYUNDAI dealer as soon as possible.

When operating

Hyundai Tucson: Electronic Stability Control<span lang= (ESC). When the ESC is in operation, the ESC indicator light blinks:" title="Hyundai Tucson: Electronic Stability Control (ESC)" border="0" src="images/4/page.h80.gif">

When the ESC is in operation, the ESC indicator light blinks:

  • When you apply your brakes under conditions which may lock the wheels, you may hear sounds from the brakes, or feel a corresponding sensation in the brake pedal. This is normal and it means your ESC is active.
  • When the ESC activates, the engine may not respond to the accelerator as it does under routine conditions.
  • If the Cruise Control was in use when the ESC activates, the cruise control automatically disengages. The Cruise Control can be reengaged when the road conditions allow. See Cruise Control System later in this chapter.
  • When moving out of the mud or driving on a slippery road, the engine rpm (revolutions per minute) may not increase even if you press the accelerator pedal deeply. This is to maintain the stability and traction of the vehicle and does not indicate a problem.

ESC OFF condition

When the ignition switch is placed to the ON position, the ESC indicator light illuminates, then goes off if the ESC system is operating normally.

The ESC indicator light blinks whenever the ESC is operating.

If ESC indicator light stays on, your vehicle may have a malfunction with the ESC system. When this warning light illuminates have your vehicle checked by an authorized HYUNDAI dealer as soon as possible.

The ESC OFF indicator light comes on when the ESC is turned off with the button.

WARNING

When the ESC is blinking, this indicates the ESC is active: Drive slowly and NEVER attempt to accelerate. NEVER press the ESC OFF button while the ESC indicator light is blinking or you may lose control of the vehicle resulting in an accident.

CAUTION

Driving with varying tire or wheel sizes may cause the ESC system to malfunction. When replacing tires, make sure they are the same size as your original tires for this vehicle.

ESC OFF usage

When driving

The ESC OFF mode should only be used briefly to help free the vehicle if stuck in snow or mud by temporarily stopping operation of the ESC to maintain wheel torque.

To turn ESC off while driving, press the ESC OFF button while driving on a flat road surface.

CAUTION

To prevent damage to the transaxle:

  • Do not allow wheel(s) of one axle to spin excessively while the ESC, ABS, and brake warning lights are displayed. The repairs would not be covered by the vehicle warranty. Reduce engine power and do not spin the wheel(s) excessively while these lights are displayed.
  • When operating the vehicle on a dynamometer, ensure the ESC is turned off (ESC OFF light illuminated).

✽ NOTICE

Turning the ESC OFF does not affect ABS or standard brake system operation.

Vehicle Stability Management (VSM)

Vehicle Stability Management (VSM) helps ensure the vehicle stays stable when accelerating or braking suddenly on wet, slippery and rough roads where traction over the four tires can suddenly become uneven.

WARNING

Take the following precautions when using the Vehicle Stability Management (VSM):

  • ALWAYS check the speed and the distance to the vehicle ahead. The VSM is not a substitute for safe driving practices.
  • Never drive too fast for the road conditions. The VSM system will not prevent accidents. Excessive speed in bad weather, slippery and uneven roads can result in severe accidents.

VSM operation

VSM ON condition

The VSM operates when:

  • The Electronic Stability Control (ESC) is on.
  • Vehicle speed is approximately above 9mph (15 km/h) on curve roads.
  • Vehicle speed is approximately above 18mph (30 km/h) when the vehicle is braking on rough roads.

When operating

When you apply your brakes under conditions which may activate the ESC, you may hear sounds from the brakes, or feel a corresponding sensation in the brake pedal. This is normal and it means your VSM is active.

✽ NOTICE

The VSM does not operate when:

  • Driving rearward.
  • ESC OFF indicator light is on.
  • EPS (Electric Power Steering) warning light ( Hyundai Tucson: Electronic Stability Control<span lang= (ESC). " title="Hyundai Tucson: Electronic Stability Control (ESC)" border="0" src="images/4/page.h82.gif">) is on.

VSM OFF condition

When the warning light illuminates, have your vehicle checked by an authorized HYUNDAI dealer as soon as possible.

CAUTION

Driving with varying tire or wheel sizes may cause the ESC system to malfunction. When replacing tires, make sure they are the same size as your original tires for this vehicle.

Hill-Start Assist Control (HAC)

The Hill-Start Assist Control (HAC) prevents the vehicle from rolling backwards when starting a vehicle from a stop on a hill. The system operates the brakes automatically for approximately 2 seconds and releases the brake when the accelerator pedal is depressed or after 2 seconds.

WARNING

Always be ready to depress the accelerator pedal when starting off on a incline. The HAC activates only for approximately 2 seconds.

✽ NOTICE

  • The HAC does not operate when the shift lever is in P (Park) or N (Neutral)
  • The HAC activates even though the ESC (Electronic Stability Control) is off but does not activate when the ESC has malfunctioned.

Downhill Brake Control (DBC)

The Downhill Brake Control (DBC) supports the driver come down a steep hill without depressing the brake pedal. It slows down the vehicle under 5mph (8 km/h) and lets the driver concentrate on steering the vehicle.

WARNING

Always turn off the DBC on normal roads. The DBC might activate inadvertently from the standby mode when driving through speed bumps or making sharp curves.

✽ NOTICE

  • The DBC defaults to the OFF position whenever the ignition switch is placed in the ON position.
  • Noise or vibration may occur from the brakes when the DBC is activated.
  • The rear stop light comes on when DBC is activated.

WARNING

If the DBC red indicator light illuminates, the system may have overheated or have malfunctioned. When the warning light illuminates even though the DBC system has cooled off, have your vehicle checked by an authorized HYUNDAI dealer as soon as possible.

✽ NOTICE

  • The DBC may not deactivate on steep inclines even though the brake or accelerator pedal is depressed.
  • The DBC does not operate when: The shift lever is in P (Park). The ESC is activated.

Good braking practices

WARNING

Whenever leaving the vehicle or parking, always come to a complete stop and continue to depress the brake pedal. Move the shift lever into the P (Park) position, then apply the parking brake, and place the ignition switch in the LOCK/OFF position. Vehicles with the parking brake not fully engaged are at risk for moving inadvertently and causing injury to yourself or others.

Wet brakes can be dangerous! The brakes may get wet if the vehicle is driven through standing water or if it is washed. Your vehicle will not stop as quickly if the brakes are wet. Wet brakes may cause the vehicle to pull to one side.

To dry the brakes, apply the brakes lightly until the braking action returns to normal, taking care to keep the vehicle under control at all times. If the braking action does not return to normal, stop as soon as it is safe to do so and call an authorized HYUNDAI dealer for assistance.

DO NOT drive with your foot resting on the brake pedal. Even light, but constant pedal pressure can result in the brakes overheating, brake wear, and possibly even brake failure.

If a tire goes flat while you are driving, apply the brakes gently and keep the vehicle pointed straight ahead while you slow down. When you are moving slowly enough for it to be safe to do so, pull off the road and stop in a safe location.

Keep your foot firmly on the brake pedal when the vehicle is stopped to prevent the vehicle from rolling forward.
