Closing the engine hood
- Pull the hood down until the pressure from the struts is
reduced .
- Let the hood
drop down and latch in place. Do not try to
push it shut;
it may fail to engage => &.
& WARNING
A hood that is not completely latched could fly up and block your
view while driving.

Working in the engine compartment
Be especially careful whenever you work in the engine
compartment!
Whenever you must perform any work in the engine compartment,
for example checking and filling the different fluids, there is a risk of injury, burns and accidents. To prevent personal injury always
observe the following WARNINGS. The engine compartment of any
vehicle is a hazardous area!
~ &
& WARNING
To help avoid injury, before you check anything under the hood :
• Switch off the engine.
• Remove the ignition key.
• Apply the parking brake .
& WARNING (continued)
• Move selector lever of automatic transmission to "P" (Park);
put manual transmission in Neutral .
• Always let the engine cool down. Hot components will burn
skin on contact.
• To reduce the risk of being burned, never open the hood if you
see or hear steam or coolant escaping from the engine compart
ment. Wait until no steam or coolant can be seen or heard before
carefully opening the hood .
• Keep children away from the engine compartment.
• Never spill fluids on hot engine components . They can cause a
fire.
• Never touch the radiator fan. The auxiliary electric fan is
temperature controlled and can switch on suddenly.
• Never open the coolant reservoir cap when the engine is still
warm. The coolant system is pressurized and hot coolant could
spray out.
• Protect your face, hands and arm from steam or hot engine
coolant by placing a thick rag over the cap when you open the
coolant reservoir.
• If work on the fuel system or the electrical system is necessary:
- Always disconnect the battery.
- Never smoke or work near heaters or open flames. Fluids in
the engine compartment could start a fire .
- Keep an approved fire extinguisher immediately available.
• To avoid electrical shock and personal injury while the engine
is running or being started, never touch :
- Ignition cables
- Other components of the high voltage electronic ignition
system.
• If you must perform a check or repair with the engine running: ..,

Glossary of tire and loading terminology
Accessory weight
means the co mbined we ig ht ( in excess o f those sta nda rd items
which may be rep laced) of automatic transmission, power steering,
power brakes, power w indows, powe r seats, rad io, a nd heater, to
the extent that these items are avai lab le as factory-installed equip
m ent (w hether insta lled or not).
Aspect ratio
means t he ratio o f th e height to t he w idt h of the tire in perce nt.
N umbers of 55 or lower indicate a low sidewa ll for improved
steer ing respo nse and b ette r overall ha ndl ing on dry pave ment.
Bead
means the part of the tire that is made of stee l wires, wrapped or
reinforced by ply cords and that is shaped to fit the rim.
Bead separation
means a breakdow n of the bond be tween co mponents i n the bead.
Cord
means the strands fo rmi ng the plies in the ti re.
& W ARNING (continued )
• Never mount used tires on your vehicle if you are not sure of
their "previous history. " Old used t ire s may ha ve been damaged
even though the damage cannot be seen that can lead to sudden
tire failure and lo ss of vehicle control.
• If you noti ce unusual vibration or if the vehicle pulls to one side
when driving , always stop as soon as it is safe to do so and check
the wheels and tires for damage . •
Cold tire inflation pressure
mea ns t he ti re pressure reco mm ended by the ve hicle ma nufacturer
for a tire of a designated size that has not been d riven for more tha n
a cou ple o f miles (k ilometers) at low speeds in t he t hre e ho ur per iod
before the tire pressure is measured or ad justed .
Curb weight

i nc lud ing the max imu m capac ity o f fue l, o il, and coola nt, a ir c ond i
tioning and additiona l weight of optional equipment.
Extra load tire
means a tire designed to ope rate at higher loads and at higher infla
tion pressures than the corresponding standard tire. Extra load tires
my be identified as "XL",
"xi", "EX TRA LOAD", or "RF" on the side
wa ll.
Gross Axle Weight Rating ("GAWR ")
means the load -carrying capacity of a sing le ax le system, measured
at the ti re -ground interfaces.
Gross Vehicle Weight Rating ("GVWR "l
means the ma ximum tot al l oade d weigh t of the vehicle.

7. Connect the other end of the black jumper cable to the
negative terminal (bolt head)
G) in the external starting
point @of your vehicle.
8. Route the jumper cables so that they cannot catch in any
rotating parts in the engine compartment.
Starting the engine
9. Start the engine of the vehicle providing assistance and
allow it to run at idle.
10. Now start the engine of the vehicle with the discharged
battery , wait for two to three minutes until the engine
"runs" smoothly.
11. If the engine does not start: Stop trying after 10 seconds
and then try again after about 30 seconds.
12. In the vehicle that has received start assistance, turn on
the heater blower and the rear window heating to elimi
nate any voltage peaks when disconnecting. Driving
lights must be switched off!
13. Disconnect the cable while the engine is running exactly
in
reverse order to that described in=> page 280,
"Connecting/disconnecting the jumper cable.". When
doing so, make sure that the cable cannot contact
rotating engine parts.
14. Close the cover on the posit ive terminal.
The battery is vented to the outside to prevent gases from entering
the vehicle interior. Make sure that the jumper clamps are well
connected with their
metal parts in full contact with the battery
terminals.
& WARNING
To avoid serious personal injury and damage to the vehicle, heed
all warnings and instructions of the jumper cable manufacturer.
If
in doubt, call for road service .
• Jumper cables must be long enough so that the vehicles do not
touch.
• When connecting jumper cables, make sure that they cannot
get caught in any moving parts in the engine compartment.
• Before you check anything in the engine compartment, always
read and heed all WARNINGS=>
page 209, "Engine compartment" .
0 Note
Improper hook-up of jumper cables can ruin the generator.
• Always connect POSITIVE(+) to POSITIVE (+l, and NEGATIVE(-) to
NEGATIVE( -) ground post of the battery manager control unit.
• Check that all screw plugs on the battery cells are screwed in
firmly. If not, tighten plugs prior to connecting clamp on negative
battery terminal.
• Please note that the procedure for connecting a jumper cable as
described above applies specifically to the case of your vehicle
being jump started. When you are giving a jump start to another
vehicle , do
not connect the negative(-) cable to the negative 1-1
terminal on the discharged battery ©-Instead, securely connect
the negative (-1 cable to either a solid metal component that is
firmly bolted to the engine block or to the engine block itself . If the
battery that is being charged does not vent to the outside, escaping
battery gas could ignite and explode! •
