Cars with transmission four leading wheels (4WD)
Depending on the road conditions, you can choose a rotation of the switch 1 one of the following modes:
- 4WD Lock.
To turn on this mode, turn the switch 1 to the AUTO position
In AUTO mode, the torque is automatically distributed between the front and rear wheels depending on the road conditions and velocity of the car
This position improves the resistance of the car on the road.Use this mode on any road (dry coating, snow, slippery road I.D.) or when towing a trailer, residential trailer, etc.For this mode, the indication on the instrument panel is not provided
To enable this mode, rotate the switch 1 to the 2WD position.2WD warning lamp lights on the instrument shield
In 2WD mode, only front wheels are used as the lead.
You need to use this mode on dry roads with good clutch
To turn off this mode, rotate the switch 1 to the AUTO position.2wd warning lamp goes out on the instrument panel
4WD Lock mode
To turn on this mode, turn the switch 1 to the 4WD Lock position
Then the switch returns to the AUTO position.4WD LOCK warning lamp lights on the instrument panel
In 4WD Lock mode, the torque is distributed between the front and rear wheels in proportion, optimal for the movement of the car under roads
This mode should be used only outside passage roads (examples: dirt, steep slopes, sand)
To turn off this mode, turn the switch 1 again to the 4WD Lock position. The warning lamp on the instrument panel will go out.
When stopping the 4WD LOCK engine, it remains on for one minute
After one minute, the system switches to 2WD or AUTO mode depending on the position of the switch
If the car moves in 4WD Lock mode at a speed above 80 km / h or at a speed of 60-80 km / h for more than one minute, the system automatically switches back to AUTO mode. 4WD Lock warning lamp goes out
Features of all-wheel drive transmissions
The car can make an increased noise when 4WD Lock or AUTO modes are enabled.This is not a sign of malfunction.If the system detects the difference in the size of the front and rear wheels (for example, with insufficient pressure in tires, pronounced tire wear on one of the axes, etc.), it automatically goes into 2WD mode
The signal lamp lights up () And, depending on the configuration of the car, the message "Check the system appears on the instrument panel. full drive. " Go for the first opportunity to the service station of the official dealer, moving at low speed
The solution of this problem can be a replacement of tires. Always use four identical tires with the same deterioration.
If the wheels are strongly planted, the mechanical nodes are overheating
If this happens:
- First on the instrument shield, the 4WD Lock warning lamp will light up and, depending on the configuration of the car, the message "Overheating of the full drive system" will appear
The 4WD Lock mode is still on, it is recommended to stop as soon as possible for cooling the system (the warning lamp will not go out);
- If the wheel slip continues, the system automatically goes into 2WD mode and, depending on the vehicle configuration, the message "Overheating of the full drive system" appears, while when the signal lamp is blinking, it is impossible to choose another mode
In this case, it is recommended to stop as soon as possible and give the system to cool down (until the lamp flashes).
For cooling, approximately five minutes may require
When the system detects too strong the front wheels, it changes the engine operation mode to reduce the slip
The operation of the anti-lock system in Lock mode (cars with ABS)
When the 4WD Lock mode is active, the ABS mode is turned on for off-road movement.In this situation, cyclic blocking of wheels is allowed so that they can be better at the soil, which reduces the brake path on bulk soils
If this mode is enabled:
- Car maneuverability in braking mode is limited.This mode of operation is not recommended in a very weak clutch (for example, on ice);
- some noise may appear.This is normal and is not a violation of work.
The work of the stabilization system of the trajectory (ESC) and the anti-slip system when driving off-road (cars with ESC)
When moving along loose soil (sand, dirt, deep snow) It is recommended to disable ESC by pressing the "ESC" switch
In this case, only the system of separate braking of the wheels works. This system will slow down the axle wheel or wheels than the transmission of torque on wheels having a clutch with an expensive. This is especially useful when the full drive is enabled.
All functions of the ESC system are again included in acceleration above 50 km / h (60 km / h in 4WD Lock mode), after re-starting the engine or after repeatedly pressing the "ESC" switch
If the system detects a malfunction, it automatically switches to 2WD mode, the warning lamp lights up () And, depending on the configuration of the car on the instrument panel, the message "Check the system appears.full drive "
Continue the movement at moderate speed and contact the manufacturer"s service company as soon as possible.
Under some faults, the system may not switch to 2WD mode or in 4WD Lock mode.AUTO mode remains on.You need to urgently contact the manufacturer"s service station
System 4 leading wheels
- Whatever the regime is selected, do not start the engine, if not all four wheels are based on the ground, for example, when using a jack or a rigged stand
- Do not rotate the mode switch when turning turns, when moving with reversal or when the wheels are strongly touched. Choose 2WD mode, Auto or 4WD Lock, only when the car moves in a straight line
- Use only tires with the required characteristics.
- 4WD Lock mode is specifically designed to move out of passage roads. Using this regime in any other case can limit the car maneuverability and cause a breakdown of the car mechanical nodes
- Always install on all four tire wheels with the same characteristics. The use of tires of different dimensions may result in serious consequences for both the tires themselves and the gearbox, transfer box and the solester of differential.
