Uniform Tire Quality Grading Standards: a
uniform standard tograde thequ ality of tires
with rega rd totread quality, tire traction and
te mp erature characteristics. The quality grading
assessment is made bythe manufacturer follow‐
ing specifications from theU. S. go vernment. The
qu ality grade of a tire is imprinted on the side
wa ll of the tire.
Re commended tire pressure :th ere commen‐
ded tire pressure is the tire pressure specified
fo rth e tires mounted totheve hicle at thefa c‐
to ry.
The tire and information table conta insthere c‐
ommended tire pressure for cold tires, the maxi‐
mum permissible load and the maximum permis‐
sible vehicle speed.
The tire pressure table conta insthere commen‐
ded tire pressure for cold tires under various
operating conditions, i.e. loading and/or speed
of theve hicle.
Increased vehicle weight due tooptional
equipment: the combined weight of all standard
and optional equipment available forth eve hicle, re
ga rdless of whe ther it is actually ins talled on
th eve hicle or not.
Rim: the part of the wheel on which the tire is
mounted.
GA WR (Gross Axle Weight Rating): the GAWR
is the maximum gross axle load. The actual load
on an axle must ne verexc eed the gross axle
we ight rating. The gross axl e
we ight rati
ng can
be found on theve hicle identification plate on
th e B‑pillar on the driver's side.
Speed rating: the speed rating is pa rtof the tire
identification. It specifies the speed range for
which a tire is appr oved.
GV W (Gross Vehicle Weight): the gross vehicle
we ight comprises thewe ight of theve hicle
including fuel, tools, the spare wheel, accesso‐
ri es ins talled, occupants, luggage and the trailer
dr aw bar nose weight, if applicable. The gross
ve hicle weight must not exceed the gross vehicle
we ight rating GVWR as specified on theve hicle
identification plate on the B‑pillar on the driver's
side.
GV WR (Gross Vehicle Weight Rating): the
GV WR is the maximum permitted gross weight of
the fully laden vehicle (weight of theve hicle
including all accessories, occupants, fuel, lug‐
ga ge and the trailer dr awbar nose weight if appli‐
cable). The gross vehicle weight rating is speci‐
fi ed on theve hicle identification plate on the
B‑pillar on the driver's side.
Maximum weight of the laden vehicle: the
maximum weight is the sum of the unladen
we ight of theve hicle, thewe ight of the accesso‐
ri es, the maximum load and thewe ight of
optional equipment ins talled at thefa ctor y.
Kilopascal (kPa): metricunit for tire pressure .
6.9 kPa cor responds to1 psi. Ano ther unit for
tire pressure is bar.100 kilop ascal (kPa
) equals
1 bar.
Load index: in additiontothe load-bearing
index, the load index may also be imprinted on
th e side wall of the tire. This specifies the load-
bearing capacity of the tire more precisel y.
Curb weight: thewe ight of a vehicle with stand‐
ard equipment including the maximum capacity
of fuel, oil and coolant. It also includes the air
conditioning sy stem and optional equipment if

WARNING ‑ Risk of fire and injury from
antifreeze
If antifreeze comes into con tact wi thhot
component parts in the engine compart‐
ment, it may ignite.
#Allow the engine tocool down before
adding antifreeze.
#Make surethat no antifreeze spills out
next tothefiller opening.
#Thoroughly clean off any antifreeze
from component parts before starting
th eve hicle.

TEOverheating at high outside tem‐
peratures
If an inappro priate coolant is used, the
engine cooling sy stem is not suf ficiently pro‐
te cted against overheating and cor rosion at
high outside temp eratures.
#Alw ays use an appropriate coolant.
Ha ve the coolant regularly changed at a qualified
specialist workshop. The proportion of cor
rosion inhibitor/ antifreeze
concentrate in the engine cooling sy stem should
be:
RA minimum of 50% (antifreeze pr otection
down toappr oximately -35 °F (-37 °C)).
RA maximum of 55% (antifreeze pr otection
down to-49 °F (-45 °C)).
