Intelligent technology Notice about data
recorded by vehicle
control modules
Your veh icle is not equipped with an Event Da­
ta Recorder (EDR), installed by some manu­
facture rs for the express purpose of capturing
data for retrieval after an accident or crash
event . EDR's are sometimes ca lled "crash re­
corders".
Some state laws restrict the retr ieval or down­
loading of data stored by EDR's that were in­
stalled in a vehicle for the express purpose of
retrieving data after an accident or crash
event without the owner's consent.
A lthough your vehicle is not equipped with an
EDR, it is equipped with a number of electron­
ic control modules for various vehicle systems
such as, for example, eng ine function, em is­
sion control, as well as for the airbags and
safety belts.
These electronic contro l modules also record
vehicle-re lated data during normal vehicle op­
eration for diagnostic and repair purposes.
The recording capacity of the electronic con­
trol modules is limited to data (no sound is re­
corded) and only a small amount of data is ac­
tually recorded over a ve ry limited pe riod of
time and stored when a system fault or other
cond ition is sensed by a control unit. Some of
the data then stored may re late to vehicle
speed, direction, braking as we ll as restraint
system use and performance in the event of a
crash or other condition. Stored data can only
be read and downloaded with special equip­
ment.
Electronic stabilization
program (ESP)
Description
ESP helps to improve road holding and vehicle
dynamics to help reduce the probability of
skidd ing and loss of veh icle control. It works
only when the engine is running. ESP detects certain difficult driving situat
ions, including
when the vehicle is beginning to spin (yaw) out of control and helps you to get the veh icle
back under control by se lectively braking the
wheels, and/or reducing engine power and
providing steer ing assistance to help hold the
vehicle on the driver's intended course. The in­
dicator light
liJ in the instrument cluster
blinks when ESP is taking action to help you
control the vehicle.
ESP has limitations.
It is important to remem­
ber that ESP cannot overcome the laws of
physics. It will not always be able to help out
under all conditions you may come up against.
For example, ESP may not always be able to
help you master situations where there is a
sudden change in the coefficient of friction of
the road surface. When there is a section of dry road that is suddenly covered w ith water,
slush or snow, ESP cannot perform the same
way it wou ld on the dry surface . If the vehicle
hydroplanes (rides on a cushion of water in­
stead of the road surface), ESP will not be
able to help you steer the vehicle because con­
tact with the pavement has been interrupted
and the vehicle cannot be braked or steered.
During fast cornering, particularly on winding
roads, ESP cannot always deal as effectively
with difficult driving situations than at lower
speeds. When towing a trailer, ESP is not able
to help you regain control as it would if you
were not tow ing a trailer.
Always adjust your speed and driving style to road, traffic; and weather condit ions. ESP can­
not override the vehicle's physical limits, in­
crease the available traction, or keep a ve hicle
on the road if road departure is a result of
driver inattention. Instead, ESP improves the
poss ibility of keeping the vehicle unde r con­
trol and on the road during extreme maneu­
vers by using the driver's steering inputs to
help keep the vehicle going in the intended di­
rection . If you are traveling at a speed that
causes you to run off the road before ESP can
provide any assistance, you may not experi­
ence the benefits of ESP .

Determining correct load limit
Use the example below to cal­
culate the total weight of the
passengers and luggage or oth­
er things that you plan to trans­
port so that you can make sure
that your vehicle will not be overloaded.
Steps for Determining
Correct Load Limit
1. Locate the statement "THE
COMBINED WEIGHT OF OC­
CUPANTS AND CARGO
SHOULD NEVER EXCEED XXX KG OR XXX LBS" on your ve­
hicle's placard (tire inflation
pressure label)
¢ page 242,
fig. 184.
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 pas­ sengers from
"XXX" kilo­
grams or
"XXX" pounds
shown on the sticker
¢ page 242, fig. 184.
4. The resulting figure equals
the available amount of car­
go and luggage load capaci­
ty. For example, if the
"XXX"
amount equals 1400 lbs.
Tires and wheels
and there will be five 150
lbs. passengers in your vehi­
cle, the amount of available
cargo and luggage load ca­ pacity is 650 lbs. (1400-7 50
(5
X 150) = 650 lbs.)
5. Determine the combined
weight of luggage and cargo
being loaded on the vehicle.
That weight may not safely exceed the available cargo
and luggage load capacity
calcu lated in Step
4.
6. If your vehicle will be towing
a trailer, load from your trail­
er will be transferred to your
vehicle. Consult this manual
to determine how this re­
duces the available cargo
and luggage load capacity of
your vehicle.
,...Check the tire sidewall
(¢page 249, fig. 188) to de­
termine the designated load rating for a specific tire.

Emergency situations
General
This chapter i s intended for trained emer­
gency crews and working personnel who have the necessary tools and equipment to
perform these operations.
Starting by pushing or
towing
CD Note
Ve hicles w ith an automatic tra nsmission
cannot be started by pus hing o rtowi ng.
Starting with jumper
cables
If necessary, the engine can be started by
connecting it to the battery of another vehi ­
cle.
If the engine shou ld fail to start because of a
discha rged o r wea k battery, the battery can be
connected to the battery o f
another vehicle,
using a
pair of jumper cables to start the en­
g ine.
Jumper c ables
Use only jumper cables of sufficiently la rge
c ross section to carry the starter c urrent safe­
l y . Refer to the man ufacturer's specifications.
Use only jumper cables with
insulated te rm i­
na l clamps wh ic h are d istinctly mar ked:
plus(+) cable in mos t cases co lore d red
minus (-) cable
in most cases colored black .
A WARNING

connecting a jumpe r cab le, you must
thaw the fr ozen battery c omp lete ly, ot h­
erwise it could explode.
- Do not allow battery acid to contact eyes
or skin. Fl ush any contacted area with

- Improper use of a booster battery to start a vehicle may cause an explosion.
- Vehicle batter ies genera te exp losive gas­
es. Keep spar ks, flame and lighted c iga ­

be weakened.
- Us e of batter ies of differe nt voltage or
