If the battery is fullyd ischarged, leave the battery that is being used to jump-start connected
for afew minutes before attempting to start. This charges the battery slightly.
R Make sure that the two vehicle sdonot touch.
Make sure that:
R the jumper cablesa re not damaged.
R when the jumper cablesa re connected to the battery, uninsulated sections of the terminal
clamp do not come into contact with other metal sections.
R the jumper cablesc annot come into contact with parts such as the V-belt pulley or the fan.
These parts move when the engine is started and whileitisr unning.

GVWR (Gross Vehicl
eWeight Rating)
The GVWR is the maximu mpermitted gross
weight of the fullyl oaded vehicle (weight of
the vehicle including all accessories, occu-
pants, fuel,l uggage and the drawbar nose-
weight if applicable).T he gross vehicle weight
rating is specified on the vehicle identification plate on the B-pilla ronthe driver's side.
Maximum loaded vehicle weight
The maximu mweight is the sum of the curb
weight of the vehicle ,the weight of the acces-
sories ,the total loadl imitand the weight of
the optional equipment installed at the fac-
tory.
Kilopascal (kPa)
Metric unit for tire pressure. 6.9 kPa is the
equivalent of 1psi.A nother unit for tire pres-
sure is bar. There are 100 kilopascals (kPa) to
1b ar.
Load index
In addition to the load-bearing index, the load index may alsobei mprinted on the sidewallof
the tire. This specifies the load-bearing capa-
city more precisely.
Curb weight
The weight of avehicle with standard equip-
ment including the maximu mcapacity of fuel,
oil and coolant. It alsoi ncludes the air-condi-
tioning system and optional equipment if
these are installed in the vehicle ,but does not
includ epassengers or luggage.
Maximum load rating
The maximu mloadr ating in kilograms or
pounds is the maximu mweight for which a
tire is approved.
Maximum permissible tire pressure
Maximu mpermissibl etire pressure for one
tire.
Maximum load on one tire
Maximu mloadono ne tire. This is calculated
by dividing the maximu maxle loadofo ne axle
by two. PSI (pounds per square inch)
As
tandard unit of measure for tire pressure.
Aspec tratio
Relationshi pbetwee ntire heigh tand tire
width in percent.
tire pressure
This is pressure inside the tire applying an
outward force to each square inch of the tire's surface. The tire pressure is specified in
pounds per square inch (psi), in kilopascal
(kPa) or in bar. The tire pressure shoul donly
be corrected when the tires are cold. For this,
the vehicle must have been stationary for at
least three hours or not have traveled more
than 1.6 km (1 mile)int his time.
Tire pressure of coldt ires
The tires are cold:
R if the vehicle has been parked without
direct sunlight on the tires for at least three
hours and
R if the vehicle has not been driven more than
1m ile (1.6 km)
Tread
The part of the tire that comes into contact
with the road.
Bead
The tire beade nsures that the tire sits
securel yonthe wheel. There are severa lsteel
wiresint he beadtop revent the tire from
coming loose from the wheelr im.
Sidewall
The part of the tire betwee nthe tread and the
bead.
Weight of optional extras
The combined weight of those optional extras
that weigh more than the replaced standard
part and more than 2.3 kilograms (5 lbs).
These optional extras, such as high-perform-
ance brakes, level control, aroof rack or a
high-performance battery, are not included in Alla
bout wheels and tires
