Road Test - Suzuki Baleno Manual

ROAD TEST

This test is to check if upshift and downshift take place at specified
speeds while actually driving vehicle on a level road.
WARNING:
D Carry out the test in very little traffic area to prevent an
accident.
D The test requires 2 persons, a driver and a tester.
1) Warm up engine.
2) With engine running at idle, shift selector lever to D range.
3) i) Accelerate vehicle speed by depressing accelerator pedal
very little (within 4 deg. of throttle valve opening).
ii) Check if upshift takes place from 1st to 2nd at about 18 km/h
(11 mile/h) and from 2nd to 3rd at about 30 km/h (19 mile/h).
iii) Stop vehicle once. Then start it again and while accelerating
by depressing accelerator pedal fully, check if upshift takes
place from 1st to 2nd at 60 km/h (37 mile/h) and from 2nd
to 3rd at 113 km/h (70 mile/h).
iv) Stop vehicle again.
v) Start vehicle and keep it running at 25 km/h (15 mile/h) and
then release accelerator pedal completely. 1 or 2 seconds
later, depress accelerator pedal fully and check if downshift
from 2nd to 1st takes place.
vi) Keep vehicle running at 75 km/h (47 mile/h) and in the same
way as in step v), check if downshift from 3rd to 2nd takes
place.
vii)If upshift or downshift fails to take place at each specified
speed in the road test, possible causes for such failure are
as follows. Check each part which is suspected to be the
cause.
