Solutions The
engine doesnot
start. Youcannot hear
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
sound. The
coolant levelistoo low. Thecoolant istoo hotand theengine isno
longer beingcooled sufficiently.
X Stop assoon aspossible andallow theengine andthecoolant to
cool down.
X Check thecoolant level(Ypage 263). Observe thewarning notes
as you dosoand add coolant ifnecessary. Notes

Overview ofTire Quality GradingStand -

TireQuality Grading Standards areU.S.
governmen tspecifications. Theirpurpose isto
provide driverswithuniform reliableinformation
on tire performance data.Tiremanufacturers
have tograde tiresusing threeperformance fac-
tors: 0043tread weargrade, 0044tract iongrade and
0087 temperature grade.Theseregulations donot
apply toCanada. Nevertheless, alltires soldin
North America areprovided withthecorre-
sponding qualitygrading markings onthe side-
wall ofthe tire.
Quality gradescanbefound, whereapplicab le,
on the tire sidewal lbetween treadshoulder and
maximum sectionwidth. Example:
R Tread weargrade: 200
R Tra ction grade: AA
R Temper aturegrade: A
All passenger cartires must confor mto the stat-
utory safety requirements inaddition tothese
grades.
i The
actual values fortires arevehicle-spe-
cific andmay deviate fromthevalues inthe
illustration.
Tread wear The
treadwear gradeisacomparative rating
based onthe wear rateofthe tire when tested
under controlled condition son aspecified U.S.
governmen tcourse. Forexample, atire graded
150 would wearoneandone-half timesaswell
on the governmen tcourse asatire graded 100.
The relative performance oftires depends upon
the actual condition sof their use,however, and
may depart significantly fromthenorm dueto
variations indriving habits, service practices
and differences inroad characterist icsand cli-
mate.
Tra ction G
WARNING
The tract iongrade assigned tothis tireis
based onstraight- aheadbraking traction
tests, anddoes notinclude acceleration, cor-
nering, hydropla ning,orpeak tractionchar-
acteristic s.
! Avoid
wheelspin. Thiscanlead todamage to
the drive train.
The tract iongrades –from highest tolowest –
are AA, A,Band C.Those grades represent the
tire's abilityto stop onwet pavement asmeas-
ured under controlled condition son specified
governmen ttest surfaces ofasphalt andcon-
crete. Atire marked Cmay have poortraction

The safe speed onawet, snow covered oricy
