The gauge indicates the temperature level of the engine coolant. The
red zone at 'H' indicates temperatures higher than normal.
Avoid driving, when the pointer is in the red zone. It indicates engine
overheating, which may be due to insufficient coolant in the radiator or
due to any other defect. Take the car to the nearest Authorised Service
outlet for necessary attention.
CAUTION CAUTIONCAUTION CAUTION
CAUTION
Never remove the radiator pressure cap from radiator when the
engine is hot. Do not restart the engine until the problem has
been duly attended.
Fuel Gauge Fuel GaugeFuel Gauge Fuel Gauge
Fuel Gauge
The fuel gauge indicates the approximate fuel level in the tank. Refill
the fuel tank at the earliest, when the needle touches the red band
(indicating reserve capacity has been reached.), a visual warning
indication (Amber coloured) comes 'ON' indicating the fuel level is low.

Gear box has all synchromesh gears including reverse. The 5th gear is
an over drive.
When shifting the gear up or down make sure you press the clutch
pedal fully and shift to the next gear and then release the clutch pedal
gradually.
NOTICE NOTICENOTICE NOTICE
NOTICE
Do not rest your foot on the clutch pedal during driving. This can
cause clutch wear and damage.
Before shifting in to reverse gear bring your vehicle to a complete stop
and depress the clutch pedal fully.
Do not shift into reverse gear with vehicle moving forward. While
shifting the gears it is recommended to shift at the speeds given in
the table.
You can get extra braking from the engine when slowing down by
shifting to a lower gear.
This can help you to maintain a safe speed and prevent your brakes
from overheating while going down a steep hill.
NOTICE NOTICENOTICE NOTICE
NOTICE
Avoid excessive revving up of engine rpm.

Presence of dirt in coolant chokes up passages in radiator,
cylinder head and crankcase, thereby causing overheating of
engine.
To prevent rust formation and freezing of coolant inside the
passages of radiator, crankcase and cylinder head use premixed
coolant as recommended.
It is recommended that the entire cooling system should
be drained and filled with fresh premixed coolant.

Engine Cooling System
If engine overheating occurs, there could be a fault in the
cooling system which may be on account of :
1. Less coolant in the cooling system or dirt/scale having
accumulated inside cooling water passages especially
in the radiator core.
2 . Choking of radiator passages due to foreign material or
damages.
3. Defective thermostat.
4. Defective coolant temperature sensor.
5 . Non operation of electrically operated fans (Controlled
by ECU).
6. Coolant leakage.
7. Radiator cap not sealing properly.
8 . A.C. condenser fan not working
9. Excessive refrigerant charging in the A.C. system.
10. No communication between auxiliary tank and radiator.
