Fixed Mast Antenna (Retractable
Hardtop)
The fixed mast antenna can withstand most car washes
without being damaged as long as it is securely
attached to the base. If the mast becomes slightly bent,
straighten it out by hand. If the mast is badly bent,
replace it.
Occasionally check to make sure the antenna is
tightened to its base. If tightening is required, tighten
by hand.
Backglass Antenna (Coupe and
Sedan)
The AM-FM antenna is integrated with the rear window
defogger, located in the rear window. Make sure that
the inside surface of the rear window is not scratched
and that the lines on the glass are not damaged. If
the inside surface is damaged, it could interfere
with radio reception. For proper radio reception, the
antenna connector needs to be properly attached to the
post on the glass.If a cellular telephone antenna needs to be attached to
the glass, make sure that the grid lines for the AM-FM
antenna are not damaged. There is enough space
between the grid lines to attach a cellular telephone
antenna without interfering with radio reception.
Notice:Using a razor blade or sharp object to clear
the inside rear window can damage the rear
window antenna and/or the rear window defogger.
Repairs would not be covered by the vehicle
warranty. Do not clear the inside rear window with
sharp objects.
Notice:Do not apply aftermarket glass tinting with
metallic lm. The metallic lm in some tinting
materials will interfere with or distort the incoming
radio reception. Any damage caused to your
backglass antenna due to metallic tinting materials
will not be covered by the vehicle warranty.
XM™ Satellite Radio Antenna
System
The XM Satellite Radio antenna is located on the roof
(coupe and sedan) or the rear (retractable hardtop)
of the vehicle. Keep the antenna clear of obstructions
for clear radio reception.

If things like suitcases, tools, packages, or
anything else are put inside the vehicle, they
will go as fast as the vehicle goes. If you have
to stop or turn quickly, or if there is a crash, they
will keep going.
{WARNING:
Things you put inside the vehicle can strike
and injure people in a sudden stop or turn,
or in a crash.
•Put things in the cargo area of the
vehicle. In the cargo area, put them as
far forward as you can. Try to spread the
weight evenly.
•Never stack heavier things, like
suitcases, inside the vehicle so that some
of them are above the tops of the seats.
•Do not leave an unsecured child restraint
in the vehicle.
•When you carry something inside the
vehicle, secure it whenever you can.
•Do not leave a seat folded down unless
you need to.
Towing
Towing Your Vehicle
To avoid damage, the disabled vehicle should be towed
with all four wheels off the ground. Consult your dealer/
retailer or a professional towing service if the disabled
vehicle must be towed. SeeRoadside Assistance
Program on page 8-7.
To tow the vehicle behind another vehicle for
recreational purposes, such as behind a motorhome,
see “Recreational Vehicle Towing” following.
Recreational Vehicle Towing
Recreational vehicle towing means towing the vehicle
behind another vehicle – such as behind a motorhome.
The two most common types of recreational vehicle
towing are known as dinghy towing and dolly towing.
Dinghy towing is towing the vehicle with all four wheels
on the ground. Dolly towing is towing the vehicle with
two wheels on the ground and two wheels up on a device
known as a dolly.
5-23

Here are some important things to consider before
recreational vehicle towing:
•What’s the towing capacity of the towing vehicle?
Be sure to read the tow vehicle manufacturer’s
recommendations.
•How far will the vehicle be towed? Some vehicles
have restrictions on how far and how long they
can tow.
•Does the vehicle have the proper towing
equipment? See your dealer/retailer or trailering
professional for additional advice and equipment
recommendations.
•Is the vehicle ready to be towed? Just as preparing
the vehicle for a long trip, make sure the vehicle is
prepared to be towed. SeeBefore Leaving on a
Long Trip on page 5-13.
Dinghy Towing From the Front
If the vehicle has the 3.9L V6 engine with the four-speed
automatic transmission, the vehicle cannot be dinghy
towed.
If the vehicle does not have the 3.9L V6 engine with a
four-speed automatic transmission, it can be dinghy
towed.When dinghy towing the vehicle, the vehicle should be
run at the beginning of each day and at each RV fuel stop
for about five minutes. This will ensure proper lubrication
of transmission components.
For vehicles that can be dinghy towed with all four
wheels on the ground:
1. Position the vehicle to tow and then secure it to the
towing vehicle.
2. Shift the transmission to P (Park) and turn the
ignition to LOCK/OFF.
5-24

Dolly Towing From the Front
Tow the vehicle with the two rear wheels on the ground
and the front wheels on a dolly:
To tow the vehicle with two wheels on the ground and
a dolly:
1. Put the front wheels on a dolly.
2. Put the gear shift lever in P (Park).
3. Set the parking brake.
4. Clamp the steering wheel in a straight-ahead
position with a clamping device designed for towing.5. Remove the key from the ignition.
6. Secure the vehicle to the dolly.
7. Release the parking brake.
Dolly Towing From the Rear
Notice:Towing the vehicle from the rear could
damage it. Also, repairs would not be covered by
the vehicle warranty. Never have the vehicle towed
from the rear.
Do not tow the vehicle with the rear wheels on a dolly.
5-26

Pulling A Trailer
Here are some important points:
•There are many different laws, including speed limit
restrictions, having to do with trailering. Make sure
the rig will be legal, not only where you live but
also where you will be driving. A good source for
this information can be state or provincial police.
•Do not tow a trailer at all during the first 1,000 miles
(1600 km) the new vehicle is driven. The engine,
transmission or other parts could be damaged.
The repairs would not be covered by the vehicle’s
warranty.
•Then, during the first 500 miles (800 km) that a
trailer is towed, do not drive over 50 mph (80 km/h)
and do not make starts at full throttle. This helps
the engine and other parts of the vehicle wear in
at the heavier loads.
•Obey speed limit restrictions when towing a trailer.
Do not drive faster than the maximum posted speed
for trailers, or no more than 55 mph (90 km/h), to
save wear on the vehicle’s parts.
•Do not tow a trailer when the outside temperature is
above 100°F (38°C).Three important considerations have to do with weight:
•the weight of the trailer,
•the weight of the trailer tongue
•and the total weight on the vehicle’s tires.
Weight of the Trailer
How heavy can a trailer safely be?
It should never weigh more than 1,000 lbs (454 kg).
But even that can be too heavy.
It depends on how the rig is used. For example, speed,
altitude, road grades, outside temperature and how
much the vehicle is used to pull a trailer are all important.
It can depend on any special equipment on the vehicle,
and the amount of tongue weight the vehicle can carry.
See “Weight of the Trailer Tongue” later in this section
for more information.
Maximum trailer weight is calculated assuming only the
driver is in the tow vehicle and it has all the required
trailering equipment. The weight of additional optional
equipment, passengers and cargo in the tow vehicle
must be subtracted from the maximum trailer weight.
Ask your dealer/retailer for trailering information or
advice, or write us at our Customer Assistance Offices.
SeeCustomer Assistance Offices on page 8-6for
more information.
