Hyundai Sonata: Transmission / Ecoshift dual clutch transmission

Ecoshift dual clutch transmission operation

The Ecoshift dual clutch transmission has seven forward speeds and one reverse speed.

The individual speeds are selected automatically in the D (Drive) position.

WARNING

To reduce the risk of serious injury or death:

• ALWAYS check the surrounding areas near your vehicle for people, especially children, before shifting a vehicle into D (Drive) or R (Reverse).
• Before leaving the driver's seat, always make sure the shift lever is in the P (Park) position, then set the parking brake, and place the ignition switch in the LOCK/OFF position. Unexpected and sudden vehicle movement can occur if these precautions are not followed.
• Do not use engine braking (shifting from a high gear to lower gear) rapidly on slippery roads. The vehicle may slip causing an accident.

CAUTION

• To avoid damage to your transaxle, do not try to accelerate in R (Reverse) or any forward gear position with the brakes on.
• When stopped on slope, do not hold the vehicle with accelerator pedal. Use the service brake or the parking brake.

• The Ecoshift dual clutch transmission gives the driving feel of a manual transmission, yet provides the ease of a fully automatic transmission. Unlike a traditional automatic transmission, the gear shifting can be felt (and heard) on the Ecoshift dual clutch transmission.
  - Think of it as an automatically shifting manual transmission.
  - Shift into Drive range and get fully automatic shifting, similar to a conventional automatic transmission.
• Ecoshift dual clutch transmission adopts dry-type dual clutch, which is different from torque converter of automatic transmission, and shows better acceleration performance during driving. But, initial launch might be little bit slower than Automatic Transmission.
• The dry-type clutch transfers torque and provides a direct drive feeling which may feel different from a conventional automatic transmission with a torque converter. This may be more noticeable when starting from a stop or low vehicle speed.
• When rapidly accelerating at lower vehicle speeds, the engine could rev up to higher engine RPM depending on the driving condition.
• For smooth uphill launches, press down the accelerator pedal smoothly depending on the current conditions.
• If you release your foot from the accelerator pedal at low vehicle speed, you may feel strong engine brake, which is similar to manual transmission.
• When driving downhill, you may use Manual shift mode and press the paddle shifters (except 1.6 TGDI engine) to downshift to a lower gear in order to control your speed without using the brake pedal excessively.
• When you turn the engine on and off, you may hear clicking sounds as the system goes through a self test. This is a normal sound for the Ecoshift dual clutch transmission.

WARNING

Due to transmission failure, you may not continue to drive and the position indicator (D,R) on the cluster will blink. Contact an authorized HYUNDAI dealer and have the system checked.

NOTICE

• To hold the vehicle on a hill use the foot brake or the parking brake. If the vehicle is held by applying the accelerator pedal on a hill the clutch and transmission will be overheated resulting in damage. At this time, a warning message will appear on the LCD display and you may feel a vibration.
• If the clutch becomes overheated by excessive use of the clutch to hold on a hill, you may notice a shudder feeling and a blinking display on the instrument cluster. When this occurs, the clutch is disabled until the clutch cools to normal temperatures. If this occurs, pull over to a safe location, shift into P (Park) and apply the foot brake for a few minutes.
• If the LCD warning is active, the foot brake must be applied.
• Ignoring the warnings can lead to damage to the transmission.
• If the display continues to blink, for your safety, contact an authorized HYUNDAI dealer and have the system checked.

• Under certain conditions such as repeated launch on steep grades, the clutch in the transmission could overheat. When the clutch is overheated, the safe protection mode engages. If the safe protection mode engages, the gear position indicator on the cluster blinks with a chime sound. At this time, a warning message will appear on the LCD display and driving may not be smooth. If you ignore this warning, the driving condition may become worse.To return the normal driving condition, stop the vehicle and apply the foot brake for a few minutes before driving off.
• Repetitive kick downs may lead to overheating of the transmission. This will lead to change in the vehicle speed shift pattern, and illuminate some warning message. To return the normal driving condition, refrain from kick down speed changes. When the warning message illuminates, park the vehicle at a safe location.
• If the ecoshift dual clutch transmission starts to become overheated, the gear shift characteristics may change. Gear shifts may become more abrupt. If continued operation includes frequent and continuous upshifts and downshifts, the overheat warning message on the cluster LCD display may illuminate. If this occurs, stop the vehicle, apply the brakes or shift the vehicle to P (Park), and allow the transmission to cool with engine on. When possible, continue to drive the vehicle smoothly while trying to avoid frequent upshifting and downshifting.
• Gear shifts may be more noticeable than a conventional automatic transmission. This is a normal characteristic of this type of Ecoshift dual clutch transmission.
• During the first 1000 miles, you may feel that the vehicle may not be smooth when accelerating at low speed. During this break-in period, the shift quality and performance of your new vehicle is continuously optimized.
• Always come to a complete stop before shifting into D (Drive) or R (Reverse).
• Do not put the shift lever in N (Neutral) while driving.

The indicator in the instrument cluster displays the shift lever position when the ignition switch is in the ON position.

P (Park)

Always come to a complete stop before shifting into P (Park).

To shift from P (Park), you must depress firmly on the brake pedal and make sure your foot is off the accelerator pedal.

If you have done all of the above and still cannot shift the lever out of P (Park), see "Shift-Lock Release" on page 5-25.

The shift lever must be in P (Park) before turning the engine off.

WARNING

• Shifting into P (Park) while the vehicle is in motion may cause you to lose control of the vehicle.
• After the vehicle has stopped, always make sure the shift lever is in P (Park), apply the parking brake, and turn the engine off.
• Do not use the P (Park) position in place of the parking brake.

R (Reverse)

Use this position to drive the vehicle backward.

CAUTION

Always come to a complete stop before shifting into or out of R (Reverse); you may damage the transmission if you shift into R (Reverse) while the vehicle is in motion.

N (Neutral)

The wheels and transmission are not engaged.

Use N (Neutral) if you need to restart a stalled engine, or if it is necessary to stop with the engine ON. Shift into P (Park) if you need to leave your vehicle for any reason.

Always depress the brake pedal when you are shifting from N (Neutral) to another gear.

WARNING

Do not shift into gear unless your foot is firmly on the brake pedal. Shifting into gear when the engine is running at high speed can cause the vehicle to move very rapidly. You could lose control of the vehicle and hit people or objects.

D (Drive)

This is the normal driving position. The transmission will automatically shift through a seven-gear sequence, providing the best fuel economy and power.

For extra power when passing another vehicle or driving uphill depress the accelerator pedal further until you feel the transmission downshift to a lower gear.

The DRIVE MODE switch, located on the shift lever console, allows the driver to switch from NORMAL mode to SPORT or ECO mode.

NOTICE

Always ensure vehicle is stationary, at a complete stop, before selecting D (Drive).

Manual shift mode

Whether the vehicle is stationary or in motion, Manual shift mode is selected by pushing the shift lever from the D (Drive) position into the manual gate. To return to D (Drive) range operation, push the shift lever back into the main gate.

In Manual shift mode, moving the shift lever backwards and forwards will allow you to select the desired range of gears for the current driving conditions.

+ (Up) : Push the lever forward once to shift up one gear.

- (Down) : Pull the lever backwards once to shift down one gear.

Information

• Only the seven forward gears can be selected. To reverse or park the vehicle, move the shift lever to the R (Reverse) or P (Park) position as required.
• Downshifts are made automatically when the vehicle slows down. When the vehicle stops, 1st gear is automatically selected.
• When the engine rpm approaches the red zone the transmission will upshift automatically.
• If the driver presses the lever to + (Up) or - (Down) position, the transmission may not make the requested gear change if the next gear is outside of the allowable engine rpm range. The driver must execute upshifts in accordance with road conditions, taking care to keep the engine rpms below the red zone.
