the starter motor. The
on-board voltageistoo low because thebattery istoo weak or
discharged.
X Jump-start thevehicle (Ypage 282).
If the engine doesnotstart despite attemptsto jump-st artit:
X Consult aquali fiedspecialist workshop. The
starter motorwasexposed toathermal loadthatwastoohigh.
X Allow thestarter motortocool down forapproximately twominutes.
X Try tostart theengine again.
If the engine stilldoes notstart:
X Consult aquali fiedspecialist workshop. The
engine isnot running
smoothly andismisfir-
ing. There
isamalfunction inthe engine electron icsorinamechanical
componen tof the engine management system.
X Only depress theaccelerator pedalslightly.
Otherwise, non-combusted fuelmay getinto thecatalytic converter
and damage it.
X Have thecause rectified immediately ataqual ified specialist work-
shop. The
coolant temperature
gauge shows avalue
above 248‡(120 †).
The coolant warning
lamp mayalsobeon and
a warning tonemay
