Rotation and replacement of wheels

1 Rotation can be carried out at emergence of signs of uneven wear of protectors. However remember that in case of successful rotation of all four wheels you eventually should replace all tires at the same time.
As carrying out this procedure demands a car raising over the earth and removals of wheels, check at the same time and operation of brake mechanisms (address to the Section of Check of brake system).

Even if you are not going to make rotation, at least check reliability of an inhaling of bolts of fastening of wheels.


2 At faster wear of forward tires it is recommended to interchange the position lobbies and back tires. Thus, service life of all four tires is equalized.
3 Address to information in Poddomkrachivaniye's Section and towage for the correct raising of the car when replacing a wheel.
4 The car should be lifted on the elevator or to establish it on support that all four wheels were lifted over the earth. Make sure that the car is reliably fixed!

Do not replace separately any tire. It is necessary to replace both tires of one bridge. Tires with the bigger depth of a protector are installed on back wheels. Lobbies and back wheels have to have tires of the identical size and type, and at all-wheel drive cars also of one manufacturer and one execution of a protector. Sheena, worked more than 6 years, it is necessary to apply only in case of accident, thus it is necessary to be careful when driving. During the replacing and removal of tubeless tires it is necessary to change the gate surely.


5 in case of use of tires with the protector assuming the movement only in a certain direction that is specified by an arrow on a lateral surface of the tire, the specified direction needs to be observed. Only thus achievement of necessary road qualities of the car, namely lack of hydroplaning, stability on the road, the low noise level and small wear is provided. If the spare wheel owing to accident has to be established with an opposite direction of rotation, such application has to be only temporary since achievement of the road qualities of the car stated above thus is impossible. It especially belongs to the movement on the wet road. Therefore it is recommended to coordinate movement speed with conditions of the road and to reinstall the tire according to the specified direction of rotation.


Spare wheel

6 Spare wheel can be established both on a lobby, and on a back axis.
7 Spare wheel is intended only for short-term use and it should be replaced with the usual as soon as possible.
8 After installation of a spare wheel pressure in its tire has to make 4.2 bars.
9 With the established spare wheel it is impossible to exceed the speed of 80 km/h. It is necessary to avoid the maximum acceleration of the car, intensive braking and sharp turns.
10 At installation of a spare wheel the road gleam under the corresponding axis decreases approximately by 30 mm.

It is not necessary to apply spare wheels from cars of other types.

It is not allowed to establish two or more spare wheels.

Replacement of wheels

11 Take off a decorative cap of a wheel.
12 On the car standing on the earth tighten the emergency brake and weaken bolts of fastening of a wheel.
13 Lift the relevant party of the car and fix on supports.

14 Turn off the top bolt of fastening of a wheel and on its place screw an adjusting pin. Use of an adjusting pin facilitates installation of a spare wheel.

Disks from easy alloys are protected from corrosion by a transparent varnish. Be careful not to damage a varnish covering. At damage of a covering, cover a disk with a varnish coat.


15 For an exception of "prikipaniye" of disks of wheels to a nave, before installation of a wheel, apply a thin film of greasing on the nave fillet aligning a wheel disk.
16 Galvanized wheel bolts can be applied only on capital stamped disks.
17 Disks from easy alloys fasten only the chromeplated wheel bolts on which there is a conic rotating washer. This washer established under a bolt head protects a disk surface at a tightening of bolts.
18 Before a vvinchivaniye do not grease a carving of bolts of fastening of a wheel.

19 Make a tightening of bolts of fastening of a wheel evenly in some stages in diagonal sequence.

The moment of a tightening of bolts of fastening of a wheel is given in Specifications.


Antisliding chains

20 Chains have to be established only on forward wheels, as well all-wheel drive car.
21 Chains of antisliding can be established only on tires by dimension 195/65 R 15. Installation of chains of antisliding on an emergency wheel for technical reasons is not allowed.
22 It is necessary to use only close-meshed chains acting no more than on 15 mm (including castle links).
23 At installation of chains of antisliding it is necessary to take off full-size caps of wheels and decorative rings of disks. For safety reasons wheel bolts have to be protected by special caps.
24 Before the movement on a site of a way, free from snow, it is necessary to remove antisliding chains. They worsen road performance of the car, increase wear of tires and quickly collapse.
