Engine Operation - Lexus IS 350C 2014 Pds Manual

F. ROAD TEST
A comprehensive road test is vital to ensure that a perfect automobile is delivered to
each Lexus customer. We recommend that you map out a specific road test course that
includes a variety of road conditions including stop and go, highway speed and rough
road surfaces.
This will help you check for squeaks, rattles, drifts, pulls and a variety of other
conditions that must be corrected prior to delivery.
Note: Make sure protective covers are in place on the seats and carpet
prior to starting the road test.
F01. ENGINE IDLE SPEED
Check that the engine idle speed is
smooth at normal operating temperature
with the transmission in "N" or "P" posi-
tion (automatic transmission) or neutral
position (manual transmission).
F02. ENGINE OPERATION WHILE
DRIVING
a) Check engine performance over a
broad range of driving conditions includ-
ing acceleration, cruising and decelera-
tion.

and responsive.

and tachometer operations are smooth
