loss of vehicle control, but can al­
so damage important parts of the
vehicle and can lead to sudden tire failure, including a blowout
and sudden deflation that can
cause the vehicle to crash.
Your safety and that of your pas­
sengers also depends on making
sure that load limits are not ex­
ceeded. Vehicle load includes ev­
erybody and everything in and on
the vehicle. These load limits are
technically referred to as the vehi­
cle's
Gross Vehicle Weight Rat­
ing
("GVWR ") .
The "GVWR" includes the weight
of the basic vehicle, all factory in­
stalled accessories, a full tank of
fuel, oil, coolant and other fluids plus maximum load. The maxi­
mum load includes the number of
passengers that the vehicle is in­
tended to carry ("seating capaci­
ty") with an assumed weight of 150 lbs. (68 kg) for each passen­
ger at a designated seating posi­
tion and the total weight of any
luggage in the vehicle. If you tow
a trailer, the weight of the trailer
hitch and the tongue weight of
the loaded trailer must be includ­
ed as part of the vehicle load.
230
The Gross Axle Weight Rating
("GAWR") is the maximum load
that can be applied at each of the
vehicle's two axles.
The fact that there is an upper
limit to your vehicle's Gross Vehi­
cle Weight Rating means that the
total weight of whatever is being
carried in the vehicle (including
the weight of a trailer hitch and
the tongue weight of the loaded
trailer) is limited. The more pas­
sengers in the vehicle or passen­
gers who are heavier than the
standard weights assumed mean
that less weight can be carried as
luggage.
The Gross Vehicle Weight Rating and the Gross Axle Weight Rating
are listed on the safety compli­
ance sticker label located on the
driver's side B-pillar
¢ page 22 7,
fig. 190.
! WARNING
Overloading a vehicle can cause
loss of vehicle control, a crash
or other accident, serious per­
sonal injury, and even death.
-Carrying more weight than your vehicle was designed to carry will prevent the vehicle
from handling properly and

increase the risk of the loss of
vehicle control.
- The brakes on a vehicle that
has been overloaded may not
be able to stop the vehicle
within a safe distance.
-Tires on a vehicle that has
been overloaded can fail sud­
denly, including a blowout and
sudden deflation, causing loss
of control and a crash.
-Always make sure that the to­
tal load being transported -
including the weight of a trail­
er hitch and the tongue
weight of a loaded trailer -
does not make the vehicle
heavier than the vehicle's
Gross Vehicle Weight Rating.
Determining correct load
limit
Use the example below to calcu­
late the total weight of the pas ­
sengers and luggage or other
things that you plan to transport so that you can make sure that
your vehicle will not be overload­
ed.
Wheels
Steps for Determining Correct Load Limit
1. Locate the statement "THE
COMBINED WEIGHT OF OCCU­
PANTS AND CARGO SHOULD
NEVER EXCEED XXX KG OR XXX
LBS"on your vehicle's placard
(tire inflation pressure label)
~ page 227, fig. 190.
2.
Determine the combined
weight of the driver and pas­
sengers that will be riding in
your vehicle.
3. Subtract the combined weight of the driver and passengers
from
" XXX " kilograms or "XXX "
pounds shown on the sticker
¢page 227, fig. 190.
4. The resulting figure equals the
available amount of cargo and
luggage load capacity. For ex­
ample, if the
" XXX " amount
equals
1400 lbs. and there will
be five
150 lbs. passengers in
your vehicle, the amount of
available cargo and luggage load capacity is
650 lbs.
(1400-750 (5 X 150) = 650
lbs.)
5. Determine the combined weight of luggage and cargo being loaded on the vehicle.

Emergency assistance
"'Let the compressor run until the va lue specified
on the tire pressure label is reach ed
¢ page 227, fig. 191 . Switch the compressor
off after running for 12 minutes at the mos t -
danger of overheating!
A WARNING
The compressor and the tire filler hose can become extremely hot while they are running
- danger of burns!
CD Note
Switch the compressor off after running for
12 minutes at the most -danger of overheat­
ing! Allow the compressor to cool down for a
few minutes before you use it again.
Replacing wheels
Before changing a wheel
Observe the following precaut ions for your own
and your passenger's safety when changing a
wheel.
"' After you experience a tire failure, pull the car
well away from moving traffic and try to reach
level ground before you stop ¢.&_ .
"' All passengers shou ld
leave the car and move
to a safe location (for instance, behind the
guardrail) ¢.&_ .
"' Engage the
parking brake to prevent your vehi­
cle from rolling unintentionally ¢&_ .
"' Sh ift into

ing devices to alert other motorists.
- Make sure that passengers wait in a safe
place away from the vehicle and well away
from the road and traffic.
- To help prevent the vehicle from moving
suddenly and possibly slipping off the jack,
always fully set the parking brake and block
the wheel diagonally opposite the wheel be­ ing changed with the folding chocks or oth­
er objects . When one front whee l is lifted
off the ground, placing the Automat ic
T ransmission in "P" (Par k) w ill

- un leaded fue ls for vehicles with catalytic con­
verter may not be available;
- fuel may have a considerably lower octane rat­
ing . Improper fuel may cause engine damage;
- service may be inadequate due to lack of proper
service facilities, tools or testing equipment;
- r eplacement parts may not be readily available.
- Nav igation systems for veh icles built for the

Maintenance
General '
Your vehicle has been designed to help keep
maintenance requirements to a minimum. How­
ever, a certain amount of regular maintenance is
still necessary to assure your vehicle's safety,
economy and reliability . For detailed vehicle
maintenance consult your Warranty & Mainte­
nance booklet .
Under difficult operating conditions, for exam ­
ple at extremely low outside temperatures, in
very dusty regions, when towing a trailer very fre­
quently, etc., some service work should be per­
formed between the intervals specified. This ap­
plies particularly to:
- oil changes, and
- cleaning or replac ing the a ir filter .
