When moving over the pools it is necessary to lower the speed to avoid
hydroplaning, which may cause skidding and loss of control; the danger in
creases with the tires worn.
Drive the vehicle where possible without sharp acceleration and decelera
tion for this will lead to the increasing tires wear and higher fuel consumption.
To provide long and troublefree operation of the gearbox, observe the fol
lowing requirements, which will guarantee easy and noiseless gear shifting:
1. When shifting the gears, move the lever smoothly having first completely
disengaged the clutch. Too quick gear shifting will result in premature wear of
synchromesh gears or their breakdown. To increase useful life of the synchro
mesh gears it is recommended to shift from the higher to the lower gear using a
double clutch method with the intermediate increase in the engine speed with
the gearshift lever in the neutral position. Never try to change gears if the clutch
is not disengaged completely. Do not operate the pedal and the lever simulta
neously.
2. Do not engage the clutch if the gear is not changed completely.
8.3. BRAKING AND PARKING
Pneumatic disk brakes ensure steady braking efficiency. Nevertheless brake
the vehicle smoothly avoiding abrupt braking.
Do not turn off the instruments and do not remove the engine control
switch key whilst the vehicle is in motion. With the engine stopped the com
pressed air pressure drops in the brake system receivers as well as the ABS is
deactivated.
Moreover with the key removed the steering shaft will become locked by
the antitheft device and this will result in the loss of vehicle control.
In case one of the brake system circuits goes out of order the second cir
cuit provides the vehicle braking. When the parking brake is engaged, its re
leasing is possible by mechanical means only.
To provide towing of the broken vehicle it is necessary to remove screws
