Jeep Liberty: Gear Ranges
DO NOT race the engine when shifting from PARK or NEUTRAL into another gear range.
This range supplements the parking brake by locking the transmission. The engine can be started in this range.
Never attempt to use PARK while vehicle is in motion.
Apply the parking brake when leaving vehicle in this range.
When parking on a level surface, you may place the shift lever in the PARK position first, and then apply the parking brake.
When parking on a hill, apply the parking brake before placing the shift lever in PARK, otherwise the load on the transmission locking mechanism may make it difficult to move the shift lever out of PARK. As an added precaution, turn the front wheels toward the curb on a downhill grade and away from the curb on an uphill grade.
вЂў Never use the PARK position as a substitute for the parking brake. Always apply the parking brake fully when parked to guard against vehicle movement and possible injury or damage.
вЂў Your vehicle could move and injure you and others if it is not completely in PARK. Check by trying to move the shift lever rearward (with the brake pedal released) after you have placed it in PARK.
Make sure the transmission is in PARK before leaving the vehicle.
вЂў It is dangerous to move the shift lever out of PARK or NEUTRAL if the engine speed is higher than idle speed. If your foot is not firmly pressing the brake pedal, the vehicle could accelerate quickly forward or in reverse. You could lose control of the vehicle and hit someone or something. Only shift into gear when the engine is idling normally and when your foot is firmly pressing the brake pedal.
вЂў Unintended movement of a vehicle could injure those in or near the vehicle. As with all vehicles, you should never exit a vehicle while the engine is running. Before exiting a vehicle, always apply the parking brake, shift the transmission into PARK, and remove the ignition key. Once the key is removed, the shift lever is locked in the PARK position, securing the vehicle against unwanted movement.
вЂў When leaving the vehicle, always remove the key fob from the ignition and lock your vehicle.
вЂў Never leave children alone in a vehicle, or with access to an unlocked vehicle. Allowing children to be in a vehicle unattended is dangerous for a number of reasons. A child or others could be seriously or fatally injured. Children should be warned not to touch the parking brake, brake pedal or the shift lever.
вЂў Before moving the shift lever out of PARK, you must turn the ignition switch from the LOCK/OFF position to the ON/RUN position, and also press the brake pedal. Otherwise, damage to the shift lever could result.
вЂў DO NOT race the engine when shifting from PARK or NEUTRAL into another gear range, as this can damage the drivetrain.
The following indicators should be used to ensure that you have engaged the shift lever into the PARK position:
вЂў When shifting into PARK, move the shift lever all the way forward and to the left until it stops and is fully seated.
вЂў Look at the shift lever position display and verify that it indicates the PARK position.
вЂў With brake pedal released, verify that the shift lever will not move out of PARK.
This range is for moving the vehicle backward. Shift into REVERSE only after the vehicle has come to a complete stop.
Use this range when the vehicle is standing for prolonged periods with the engine running. The engine may be started in this range. Set the parking brake and shift the transmission into PARK if you must leave the vehicle.
Do not coast in NEUTRAL and never turn off the ignition to coast down a hill. These are unsafe practices that limit your response to changing traffic or road conditions. You might lose control of the vehicle and have a collision.
Towing the vehicle, coasting, or driving for any other reason with the transmission in NEUTRAL can result in severe transmission damage. Refer to вЂњRecreational TowingвЂќ in вЂњStarting And OperatingвЂќ and вЂњTowing A Disabled VehicleвЂќ in What To Do In EmergenciesвЂќ for further information.
This range should be used for most city and highway driving. It provides the smoothest upshifts and downshifts, and the best fuel economy. The transmission automatically upshifts through all forward gears. The DRIVE position provides optimum driving characteristics under all normal operating conditions.
When frequent transmission shifting occurs (such as when operating the vehicle under heavy loading conditions, in hilly terrain, traveling into strong head winds, or while towing heavy trailers), use the TOW/HAUL mode, or select the 2 range at lower speeds. Under these conditions, using TOW/HAUL mode or the 2 range will improve performance and extend transmission life by reducing excessive shifting and heat buildup.
If the transmission operating temperature exceeds normal operating limits, the powertrain controller will modify the transmission shift schedule and expand the range of torque converter clutch engagement. This is done to prevent transmission damage due to overheating.
If the transmission becomes extremely hot, the вЂњTransmission TemperatureWarning LightвЂќ may illuminate and the transmission may downshift out of Overdrive until the transmission cools down.
During cold temperatures, transmission operation may be modified depending on engine and transmission temperature as well as vehicle speed. This feature improves warm up time of the engine and transmission to achieve maximum efficiency. Engagement of the torque converter clutch is inhibited until the transmission fluid is warm (refer to the вЂњNoteвЂќ under вЂњTorque Converter ClutchвЂќ in this section). During extremely cold temperatures (-16В°F [-27В°C] or below), operation may briefly be limited to second gear only. Normal operation will resume once the transmission temperature has risen to a suitable level.
This range is used for moderate grades and to assist braking on dry pavement or in mud and snow. Begins at a stop in low gear with automatic upshift into second gear. Will not shift into third gear.
This range is used for hard pulling at low speeds in mud, sand, snow, or on steep grades. Begins and stays in low gear with no upshift. Provides engine compression braking at low speeds.
Transmission Limp Home Mode
Transmission function is monitored electronically for abnormal conditions. If a condition is detected that could result in transmission damage, Transmission Limp Home Mode is activated. In this mode, the transmission remains in second gear regardless of which forward gear is selected. PARK, REVERSE, and NEUTRAL will continue to operate. The Malfunction Indicator Light (MIL) may be illuminated. Limp Home Mode allows the vehicle to be driven to an authorized dealer for service without damaging the transmission.
In the event of a momentary problem, the transmission can be reset to regain all forward gears by performing the following steps:
1. Stop the vehicle.
2. Shift the transmission into PARK.
3. Turn the ignition switch to the LOCK/OFF position.
4. Wait approximately 10 seconds.
5. Restart the engine.
6. Shift into the desired gear range. If the problem is no longer detected, the transmission will return to normal operation.
NOTE: Even if the transmission can be reset, we recommend that you visit your authorized dealer at your earliest possible convenience. Your authorized dealer has diagnostic equipment to determine if the problem could recur.
If the transmission cannot be reset, authorized dealer service is required.
The automatic transmission includes an electronically
controlled Overdrive (fourth gear). The transmission will
automatically shift into the Overdrive gear if the following
conditions are present:
вЂў the shift lever is in the DRIVE position,
вЂў the transmission fluid has reached an adequate temperature,
вЂў the engine coolant has reached an adequate temperature,
вЂў vehicle speed is sufficiently high,
вЂў the driver is not heavily pressing the accelerator, and
вЂў the TOW/HAUL button has not been activated.
When To Use TOW/HAUL Mode
When driving in hilly areas, towing a trailer, carrying a heavy load, etc., and frequent transmission shifting occurs, press the TOW/HAUL switch to select TOW/ HAUL mode. This will improve performance and reduce the potential for transmission overheating or failure due to excessive shifting. When operating in TOW/HAUL mode, the transmission will downshift into third gear.
NOTE: TOW/HAUL mode locks out Overdrive.
The вЂњTOW/HAUL Indicator LightвЂќ will illuminate in the instrument cluster to indicate that TOW/HAUL mode has been activated. Pressing the switch a second time restores normal operation. If the TOW/HAUL mode is desired, the switch must be pressed each time the engine is started.
Torque Converter Clutch
A feature designed to improve fuel economy has been included in the automatic transmission on your vehicle.
A clutch within the torque converter engages automatically at calibrated speeds. This may result in a slightly different feeling or response during normal operation in the upper gears. When the vehicle speed drops or during some accelerations, the clutch automatically disengages.
NOTE: The torque converter clutch will not engage until the transmission fluid and engine coolant are warm [usually after 1 to 3 miles (1.6 to 4.8 km) of driving].
Because the engine speed is higher when the torque converter clutch is not engaged, it may seem as if the transmission is not shifting into Overdrive when cold.
This is normal. Pressing the TOW/HAUL switch, when the transmission is sufficiently warm, will demonstrate that the transmission is able to shift into and out of Overdrive.
