soft top compartment cover).
Hands must never be placed near the roll
bar, soft top frame, upper windshield area,
shelf behind roll bar, or soft top storage
compartment while the soft top is being
raised or lowered. Serious personal injury
may occur.
If potential danger exists, release the soft

SmartKey or SmartKey with KEYLESS-GO
*
from the starter switch, take it with you, and
lock the vehicle. Do not leave children unat-
tended in the vehicle, or with access to an
unlocked vehicle. Unsupervised use of vehi-
cle equipment can cause an accident
and/or serious personal injury.
!Never sit or place heavy objects on the
rear shelf. Doing so could cause dam-
age to the soft top and the rear shelf.

The total load weight including vehicle oc-
cupants and luggage/cargo should not ex-
ceed the load limit or vehicle capacity
weight indicated on the corresponding
placard located on the driver’s door B-pil-
lar.
The handling characteristics of a fully load-
ed vehicle depend greatly on the load dis-
tribution. It is therefore recommended to
load the heaviest items being placed to-
wards the front of the vehicle.
Always place items being carried against
rear seat backrests, and fasten them as se-
curely as possible.
The heaviest portion of the cargo should al-
ways be kept as low as possible since it in-
fluences the handling characteristics of
the vehicle.
!To prevent damage to the soft top or
luggage/cargo when lowering the roof:
load trunk only to the height of the
luggage cover
do not permit luggage/cargo to
push up the closed luggage cover
do not place anything on the shelf
behind the roll bar
do not place anything on the soft
top compartment cover
Warning!
G
Always fasten items being carried as secure-
ly as possible.
In an accident, during hard braking or sud-
den maneuvers, loose items will be thrown
around inside the vehicle and can cause in-
jury to vehicle occupants unless the items
are securely fastened in the vehicle.
To help avoid personal injury during a colli-
sion or sudden maneuver, exercise care
when transporting cargo. Put luggage or car-
go in the trunk if possible.
Never drive vehicle with trunk open. Deadly
carbon monoxide (CO) gases may enter ve-
hicle interior resulting in unconsciousness
and death.

Closing
Let the hood drop from a height of
approximately 1 ft (30 cm).
The hood will lock audibly.
Check to make sure the hood is fully
closed.
If you can raise the hood at a point
above the headlamps, then it is not
properly closed. Open it again and let it
drop with somewhat greater force.
Engine oil
The amount of oil your engine needs will
depend on a number of factors, including
driving style. Higher oil consumption can
occur when
the vehicle is new
the vehicle is driven frequently at
higher engine speeds
Engine oil consumption checks should only
be made after the vehicle break-in period.
Warning!
G
If you see flames or smoke coming from the
engine compartment, or if the coolant tem-
perature gauge indicates that the engine is
overheated, do not open the hood. Move
away from vehicle and do not open the hood
until the engine has cooled. If necessary,
call the fire department.Warning!
G
The engine is equipped with a transistorized
ignition system. Because of the high voltage
it is dangerous to touch any components
(ignition coils, spark plug sockets, diagnos-
tic socket) of the ignition system
with the engine running
while starting the engine
if ignition is “on” and the engine is
turned manually
Warning!
G
Be careful that you do not close the hood on
anyone.

tives, as these may damage the drive
