On the road ---------------~:..:.....__
Starting off with a trailer
To prevent rolling back unintentionally on an incline, do
the following:
- Keep the switch pulled and depress the accelerator. The
parking brake stays applied and p reve nts the vehicle from
rolling backward .
- You can release t he switch once you are sure t hat you are
deve loping enough forward momentum at the whee ls as
you depress the acce lerator .
Depending on the we ight of the rig (vehicle and trailer) and the
severity of the incline, yo u may roll backwards as you start. You can
prevent rol ling backwards by holding the park ing bra ke sw itch pulled
out and accelerating -just as you wou ld when starting on a hill with a
conventional hand brake .•
Emergency braking
In the event that the conventional brake system fails or
locks.
- P ull the swi tch and cont inue to pull it to s low your veh icle
with the parking brake in an emergency .
- As soon as you re lease the sw itc h or accelerate, the
braking process stops .
If you pull the switch and hold it above a speed of abou t 5 mp h (8
km/h), the emergency braking function is init iated. The vehicle is
bra ked at all fou r wheels by activat ing the hydraulic b rake system.

Applies to veh icles: w ith Hom eli nk ® universal remote control
General information
The Homelink ® feature can learn up to three radio
frequency codes for most current transmitters used for
operating garage doors, estate gates, home or outdoor
lighting systems, and other devices.
You must first program the Homelink ® transm itter before you can
use the system=>
page 182, "Programming the Home link® trans­
mitter".
I n order to program the Homelink ® transmitter for devices utilizing
rolling code, a second person on a ladder who can safe ly reach the
garage door opener motor is recommended. It is also necessary to
locate the "learn" button on your garage door opener motor. Refer to
the operating instructions for the opener, as the location and color of
this button may vary by manufacturer.
You can still use the original remote control for the device at any
time.
& WARNING
• Never use the Homelink'"' transmitter with any garage door
opener that does have not the safety stop and reverse feature as
required by federal safety standards. This includes any garage
door opener model manufactured before Aprill, 1982.
• A garage door opener which cannot detect an object, signaling
the door to stop and reverse does not meet current federal safety
standards. Using a garage door opener without these features
increases risk of serious injury or death.

ment Safety first
& WARNING
(continued)
• For safety reasons never release the parking brake or start the
engine while anyone is standing in front of the vehicle.
• A garage door or an estate gate may sometimes be set in
motion when the Homelink ® remote control is being
programmed. If the device is repeatedly activated, this can over­
strain motor and damage its electrical components -an over­
heated motor is a fire hazard!

in. WARNING
Improperly stored luggage or other items can fly through the
vehicle causing serious personal injury in the event of hard braking
or an accident. To help reduce the risk of serious personal injury:
• Always put objects, for example, luggage or other heavy items
in the luggage compartment.
• Always secure objects in the luggage compartment using the
tie-down hooks and suitable straps.
& WARNING
Heavy loads will influence the way your vehicle handles. To help
reduce the risk of a loss of control leading to serious personal
injury:
• Always keep in mind when transporting heavy objects, that a
change in the center of gravity can also cause changes in vehicle
handling:
-Always distribute the load as evenly as possible.
- Place heavy objects as far forward in the luggage compart-
ment as possible.
• Never exceed the Gross Axle Weight Rating or the Gross Vehicle
Weight Rating specified on the safety compliance sticker on the
left door jamb. Exceeding permissible weight standards can cause
the vehicle to slide and handle differently.
• Please observe information on safe driving
=> page 186.
in. WARNING
To help prevent poisonous exhaust gas from being drawn into the
vehicle, always keep the rear lid closed while driving.
• Never transport objects larger than those fitting completely
into the luggage area because the rear lid cannot be fully closed.
& WARNING (continued)
• If you absolutely must drive with the rear lid open, observe the
following notes to reduce the risk of poisoning:
-Close all windows,
- Close the power roof,
- Open all air outlets in the instrument panel,
- Switch off the air recirculation,
- Set the fresh air fan to the highest speed.
in. WARNING
Always make sure that the doors, all windows, the power roof and
the rear lid are securely closed and locked to reduce the risk of
injury when the vehicle is not being used.
• After closing the rear lid, always make sure that it is properly
closed and locked.
• Never leave your vehicle unattended especially with the rear lid
left open. A child could crawl into the vehicle through the luggage
compartment and close the rear lid becoming trapped and unable
to get out. Being trapped in a vehicle can lead to serious personal
injury.
• Never let children play in or around the vehicle.
• Never let passengers ride in the luggage compartment. Vehicle
occupants must always be properly restrained in one of the
vehicle's seating positions.
(I) Tips
Air circulation helps to reduce window fogging. Stale air escapes to
the outside through vents in the trim panel, on the left side of the
luggage compartment . Be sure to keep these slots free and open.•
