Internal maintenance

The internal maintenance shall be based on the internal cleaning, and shall be carried out after the internal cleaning.

Maintenance of instrument panel

After the instrument panel is cleaned, in order to slow down the aging of plastic parts such as the instrument panel, a layer of protective wax can be applied to the instrument panel to prolong the service life of the plastic material.

Maintenance of leather

Leather trims can be sprayed with a special leather wax and polished with a piece of dry cloth.

Maintenance of window glass

After the window glass is cleaned, glass coating products can be sprayed on it to prevent fogging of the windows in rain and snow or in winter.

Maintenance of sealing strips

Regular maintenance of the rubber sealing strips of the doors, windows and other parts of the vehicle is intended to maintain their flexibility and prolong their service life. Such maintenance can also improve the tightness, make the door easy to open, reduce the impact sound of closing the door, and prevent freezing in winter. The maintenance steps of the sealing strips are as follows:

1. Use a piece of soft cloth to remove dust and dirt from the surfaces of the sealing strips.

2. Apply special protective agent to rubber sealing strips regularly.

Tire maintenance

Defective tires will increase the risk of driving, and you should get into the habit of checking your tires before driving.

Tire pressure

It is suggested to contact the GAC Service Center to check tire pressure. If you find that the tire valve cap is missing, install a new one in time.

DANGER

◆ Insufficient tire pressure exacerbates tire deflection, and tires are extremely prone to overheating, which may lead to tread separation and tire burst. Too high or low tire pressure can accelerate tire wear, reduce vehicle maneuvering stability, and easily cause traffic accidents, injuries and even death.

WARNING

◆ T ake care t o maintain proper tire pressure to prevent accidents.

NOTE

◆ For inspection of tire pressure, the tire must be in a cold state. When the temperature increases, the tire pressure can be slightly higher than the specified value, and it is not necessary to reduce the tire pressure.

◆ When checking the tire pressure or tire inflation, balance the weight of occupants and luggage, avoid slopes and adjust the tire pressure according to vehicle load.

◆ After checking the tire pressure or tire inflation, be sure to put the tire valve cap back on the valve core.

Hidden damage

Damage to tires and rims often occurs in a hidden way, and abnormal vibration or deviation of the vehicle during driving may indicate tire damage. If you suspect that the tires are damaged, be sure to reduce the speed immediately and stop to check the tires for damage. If the damage is not visible from the outside, it is recommended to contact the GAC Service Center to check the tires as soon as possible.

Precautions for wheel failure

When driving over curbs or similar obstacles, keep a slow speed in the vertical direction of the obstacles as much as possible.

Regularly check the damage of tires, such as splitting, abrasion, shedding, deformation or bulging.

Regularly remove debris embedded in the grooves of the tire pattern.

New tires and wheels

Make sure that the dimensions, load range, rated speed and structure type of new tire are the same as those of original one.

Replace at least two tires on the same axle at the same time, rather than only one tire individually.

Do not use tires of different dimensions or types, and do not mix summer tires, all season tires and winter tires in use.

Once wheels are installed, check whether the tightening torque of the wheel bolts meets the requirements.

WARNING

◆ Never use tires that do not meet the specifications of this vehicle and have not passed the national product certification, otherwise it may cause accidents.

Winter and summer tires

◇ Winter tires

Winter tires have good grip performance on icy roads and in low- temperature environments, and have excellent braking ability, which can improve driving safety in winter. It is recommended to use winter tires while driving in icy or snowy days in winter or when the temperature is below 7°C.

Use only radial winter tires of same dimensions, load range and rated speed as original ones and approved for this vehicle.

The tread depth of winter tires shall not be less than 4 mm.

After installation of tires, check the tire inflation pressure. ◇ Summer tires

Summer is a rainy season. The tire tread depth directly affects the driving safety in rainy days. The tread depth of summer tires shall not be less than 3 mm.

◇ Winter and summer tires are designed according to their respective typical lane c onditions under the corresponding seasonal conditions. It is recommended to use winter tires in winter and summer tires in summer, otherwise the adhesion and braking ability will be poor.

If summer tires are used in severe cold conditions, cracks may appear on the tires, resulting in tire damage, increased tire noise, and loss of balance. - Winter tires may lead to decreased traction force of the vehicle on dry roads, increased road noise and shortened service life of tread. Please pay attention to the performance change of the vehicle in terms of maneuvering and braking after the winter tires are used.

When driving in atmospheric temperature rising above 7°C, in order to ensure driving safety and performance, please replace the winter tires with summer tires in time. Tires marked with rolling direction Service life of tires Some tires are marked with arrows or Service life of tires depends on tire characters indicating the rolling direction on pressure, driving style and tire assembly the sides, so these tires must be installed in the marked rolling direction. If the tire conditions. rolling direction is reversed, there may If the front tires are worn more serious than be dangers such as tire jitter, increased the rear tires, it is recommended to perform noise, accelerated wear, and significantly tire rotation for the front and rear wheels, weakened grip during driving. so as to make the service life of all tires about the same. (For tire rotation, please Instructions for storing tires refer to the "Emergency treatment - Owner If there is no rolling direction mark on the emergency - Tire rotation" section) side of the tire, before removing the tire, make a mark on the tire to indicate the Wheel balance rolling direction, and refit the tire according The wheels of the new vehicle have been to the mark to ensure the rotation direction dynamically balanced, but during the and the dynamic balance of the wheel are driving, various influences may cause unchanged. the wheels to appear unbalanced; when the steering wheel shakes during driving, The removed wheels or tires shall be the wheels may be unbalanced, and the stored in a dry place, preferably in a dark place. wheels need to be dynamically balanced.

The maximum speed for winter tires is relatively low. Do not exceed the allowable maximum speed for the tires during driving.

The unbalanced wheels may cause excessive wear on the steering system, wheel suspension mechanism and tires.

The dynamic balance must be performed after installation of new tires or repair of tires.

Wheel alignment

Wheel misalignment will cause uneven and excessive wear of the tires, affecting driving safety. If uneven and excessive wear of the tires is found, please go to the GAC Service Center to check the wheel alignment as soon as possible. Four-wheel alignment is required in the following cases:

are defects in driving ◇ There performance, such as deviation. ◇ Chassis is damaged in accidents and related parts are replaced. ◇ Suspension parts are removed or replaced. ◇ Uneven and excessive tire wear occurs.

The tires mounted on the rims shall not be stored upright, and the tires not mounted on the rims shall be stored upright (the tread surfaces shall touch the ground).

Precautions for use of tires

Please read and observe the followings when using and maintaining your tires.

WARNING

◆ Within the first 500 km, the road adhesion of new tires is unlikely to reach the best condition. Therefore, the vehicle shall be driven carefully at a moderate speed to prevent accidents.

WARNING (Cont’d)

is running, it is very easy to cause serious traffic accidents.

◆ Never use damaged tires and wheels, or use tires of which the treads have been worn to the wear indicators. ◆ Do not use old tires that have been used over six years.

◆ Do not use old wheels and tires of unknown origin under any circumstances, otherwise, the driver may lose control of the vehicle and cause traffic accidents when driving.

◆ Do not use recycled tires. The carcass of these tires may degrade as the service time passes, and the durability may also be restrained, impairing the driving safety.

CAUTION

◆ Be careful not to expose the tires to chemicals, oil, grease, fuel and brake fluid. ◆ If it is found that the vehicle is abnormally vibrating or deviating, stop the vehicle immediately and check whether the tires are damaged.

◆ Inadequate road adhesion of tires not subject to running-in period or excessively worn can directly affect the braking effect. If uneven and excessive wear of the tires is found, please go to the GAC Service Center for inspection as soon as possible.

Corrosion protection measures

The vehicle has effective corrosion protection. However, in order to reduce the risk of corrosion, please observe the followings: ◇ Perform regular vehicle washes to keep the body clean.

If you drive on salty roads in winter, or live by the sea, please have your vehicle be carefully cleaned at least once a month to reduce corrosion. - Please carefully clean the chassis on a regular basis to remove mud and dirt adhering to the chassis and wheelhouses. - Clean the chassis in time after driving on icy and snowy roads to prevent the residual deicing salt from corroding the vehicle. ◇ Check the paint and trims of the body. - If the paint layer is found to be chipped or cracked, it is recommended to contact the GAC Service Center for repairs to prevent corrosion. ◇ Keep the interior of the compartments dry. - Moisture and dust tend to accumulate under the carpet, so the underside of the carpet shall be checked frequently to ensure it is dry and clean to prevent corrosion. - When chemicals, detergents, fertilizers, salts and others are transported, they must be stored in appropriate containers, and if spills or leaks are found, they must be cleaned immediately and the compartment must be kept dry. ◇ Use mudguards.

When the vehicle runs in saline- alkali areas or on gravel roads, the mudguards can be used to prevent the adhesion of saline-alkali substances and the impact of gravels on the vehicle components.
