POWER STEERING
POWER STEERING (if installed)
Power steering is fitted for lighter steering effort and easy
manoeuverability, during driving and also help absorb the
road shocks. The system consists of steering gear box,
hydraulic pump and hydraulic tank. Pump drive is through
the poly 'V' belt from the engine. Power assistance is
available during normal operating conditions. In case of failure
in the hydraulic system, the steering can be operated
mechanically to bring the car to an Authorised Service
outlet.
CAUTION
Report any external leakage to the nearest Authorised
Service outlet.
WARNING
Do not allow fluid level to drop significantly or run out of
the reservoir during the above operation. This may induce
air into the system.
Severe damage could occur to the power steering pump
due to dry running (Running without sufficient oil and
due to severe cavitation on account of air entry due to
low oil level). This could lead to loss of power assistance,
damage and failure of the power steering system.
MAINTENANCE & CAR CARE
Do not start the engine without oil in the power steering
system. This will result in serious damage to the pump.
In case of an emergency, disconnect the pump drive
belt and then start the engine or drive slowly as vacuum
assistance for brake would not be available (as vacuum
pump is also being driven by same belt).
Always use recommended oil from sealed containers.
Any contaminated oil poured in the system will result in
damage to the pump and gear box.
Avoid mixing of different brands of oils.
