2.5.15. Councils for driving in various conditions

Before a start of motion be convinced that the parking brake is completely released — the corresponding control lamp has to be disconnected!

During the movement you do not hold a leg on a brake pedal — it can lead to a dangerous overheat and premature wear of components of brake mechanisms.

At the movement down a long or steep slope you brake, the engine on a low gear — long use of brakes can lead to their dangerous overheat.

Be careful at dispersal or braking on the slippery road — the slightest mistake can lead to a drift of the car and loss of control over driving.

Dump speed at a strong head wind.

Do not forget that the wash of the car or overcoming water obstacles can lead to moistening of components of brake mechanisms. Before continuing a trip dry brakes by several consecutive braking of the car.

Reduce speed at arrivals on borders and other obstacles.

At the parking of the car on a slope develop forward wheels so that in case of refusal brakes they rested against a border. Do not forget to cock the parking brake and to transfer AT to situation "P" (in case of RKPP it is necessary to choose back or first transfer). In case of need enclose antiretractable boots, or any suitable emphasis under wheels.

As on the models considered in the present manual the interaxal differential is not provided, it is not necessary to use the all-wheel drive mode (4WD) at movement along roads with a dry and hard coating as it is fraught with increase in a noise background and premature wear of protectors and components of the transmission line. It is not necessary to lose sight of a fuel economy factor also.

Avoid use of the parking brake in frosty weather — frosting of elements of the hummock drive can result in impossibility of an otpuskaniye of blocks. On models from AT you transfer transmission to situation "P", in case of RKPP turn on the first, or reverse gear. In case of need prop up wheels antiretractable boots.

In cold weather on the first kilometers of a trip it is necessary to warm up the main transfer of the back bridge, moving in the all-wheel drive mode.

Councils for driving in cross-country conditions

Always you seek to observe the recommended precautionary measures for the purpose of minimization of risk of hit in an emergency.

In cross-country conditions always you drive the car with extreme care. Avoid unjustified risk.

At the movement strongly holding a steering wheel in cross-country conditions, both hands covering it for a rim (not for spokes), thumbs of hands should be held from the outer side of a rim in order to avoid their reversing at breakthroughs.

Having finished the movement on water, sand or dirt, surely check efficiency of functioning of brakes, examine the car bottom on existence of the stuck foreign objects.

Always during the movement of the car seat belts of the driver and all passengers have to be fastened.

Before starting overcoming a water barrier surely measure depth of water and density of a bottom on the site of an estimated crossing. Move slowly, avoiding hit in deep holes. You watch that water did not get to the engine and other units of the car. Hit of water in an air inlet is fraught with serious internal damages of the engine. Remember that washing away of jellied lubricant from wheel bearings, is fraught with their premature exit out of operation as a result of corrosion development. Inadmissibly also hit of water in differentials, the transmission and the transfer case.

The sand and dirt accumulating on brake mechanisms can be the reason of decrease in efficiency of braking and damage of components of the brake system.

After every day of driving on off road terrain, you make careful survey of the main components of the car.

Features of driving in adverse weather conditions

Reduce speed and move more slowly, than usually in normal weather conditions on a dry paving. Remember that reactions of the car to management will be more sluggish and slowed down even if the paving looks only slightly damp. Try to influence all controls of the car smoothly. On a wet and slippery paving the sharp breakthrough of a steering wheel or careless squeezing of a brake pedal can lead to loss of control over management. At the beginning of a trip, still completely without having adapted to adverse weather conditions, show the increased care. It is especially useful to follow this rule at the movement during snowfall. It is necessary to remember that at operation of the car in warm season many useful skills of driving of the car on a slippery paving are forgotten that demands some time for their restoration.

Show extra care, driving the car during a rain as lack of practice during the dry period does not allow to be reconstructed and adapt a bridle manner for new conditions quickly.

After the long dry period the first rains do a paving especially slippery.


For traffic safety in any weather conditions it is very important to have the good review in all directions. It is worth to remember to take care also that your car remained to well noticeable drivers of other vehicles — you remember that at movement along the route inclusion of passing beam will never prevent even during daylight hours. It is more difficult to fulfill these requirements in adverse weather conditions.

Regularly check a condition of brushes of screen wipers and snuffled windshield washers. Constantly support the required liquid level in the tank of the washing liquid. Use for gas station of system of washing of glasses only liquids, the recommended brands. You watch a condition of working elements of screen wipers, you make their replacement as soon as brushes cease to purify glass properly. For prevention of condensation of moisture on the internal surface of glasses use having blown in glasses air, in case of need turn on the air conditioner.

Extra care and attention are required from the driver at commission of overtakings. Equally it is necessary to observe attentiveness, when overtaking your car by other vehicles. Splashes of water and dirt from under wheels of the overtaken truck can sharply worsen visibility through a windshield.

Coupling of tires with a paving

Regularly control air pressure in tires and degree of wear of protectors of tires (pattern depth). Both of these factors are extremely important from the point of view of good coupling of tires with a paving and prevention of the phenomenon of hydroplaning, that is sharp reduction of coupling with the road at entrance to pools. For ensuring the best controllability with the car and traffic safety at approach of a winter season use studded rubber.

During the movement constantly watch changes of road conditions which often are very unstable. Presence on the road of wet foliage can be not dangerous, than ice. Often in appearance the pure and dry paving can ice over certain sites. Especially dangerous conditions develop at air temperatures about 0 °C when pools can alternate with frost that does behavior of the car especially unpredictable.

Be careful when switching the automatic transmission in the lowered range. On a slippery covering sharp inclusion of a low gear can lead to short-term pro-slipping of driving wheels and a drift of the car

The rush of a side wind during commission of overtaking of the truck or the bus is dangerous by loss of control over management.
