Securing a load on the roof rack

WARNING
Improper use of the trailer hitch can cause accidents and injuries. An improperly installed,
incorrect, or damaged trailer hitch can cause the trailer to separate from the towing vehicle
and cause serious personal injuries.
x Only use an undamaged, properly mounted trailer hitch.
x Never repair or modify the trailer hitch.
x To reduce the risk of injury in rear-end collisions, and the risk to pedestrians and cyclists
when the vehicle is parked, always remove the ball mount when you are not towing a trailer.
x Never install a “weight distributing” or “load equalizing” trailer hitch on your vehicle. The
vehicle was not designed for these kinds of trailer hitches. The trailer hitch attachment can
fail, causing the trailer to tear loose from the vehicle.
WARNING
Improper trailer towing can cause loss of vehicle control and serious personal injury.
x Driving with a trailer and carrying heavy or large things can change the way the vehicle
handles, increase the distance it needs to stop safely, and cause accidents.
x Always secure the load properly with suitable and undamaged straps so that the load will
not shift.
x Always adapt your speed and driving to the heavier load and the weight distribution in the
vehicle. Take road, weather, traffic, and visibility conditions into account as well.
x Reduce your speed even more than you otherwise would when going downhill and under
unfavorable load, weather, or wind conditions.
x Trailers with a high center of gravity tip more easily than trailers with a low center of
gravity.
x Always avoid sudden maneuvers and hard braking.
x Be especially careful when passing other vehicles.
x Reduce speed immediately if the trailer shows the slightest sign of swaying.
x Never try to stop the swaying by accelerating.
x Always obey speed limits. In some areas, the speed limits for vehicles towing trailers are
lower than for vehicles without trailers. Never drive faster than 50 mph (80 km/h; under
exceptional circumstances 60 mph - 100 km/h) when towing a trailer. This applies even if the
local speed limit is higher.
If you are driving a new vehicle or a vehicle with a new or rebuilt engine, do not tow a trailer
during the break-in period, about 600 miles (1000 km)
If you tow a trailer, your vehicle may need maintenance more often because of the extra load it
has to move.
When you are not towing, remove the trailer hitch ball. This helps keep the trailer hitch from
causing damage to your vehicle and to others if your vehicle is hit from behind.
Some models need a trailer hitch to tow or tow-start other vehicles. You may want to always
carry the ball mount in the vehicle after it has been removed. Be sure to stow it securely.

WARNING
Exceeding the gross weight ratings for axle, tongue, vehicle, trailer or combined weight can
cause accidents and serious personal injury.
x Never exceed the specified values.
x Never let the actual weights at the front and rear axles exceed the Gross Axle Weight
Rating. Never let the combined front and rear weights exceed the Gross Vehicle Weight
Rating.
WARNING
Trailer loads that are not properly secured can shift when the vehicle is moving or braking
and suddenly change the way the vehicle handles, causing accidents and severe injuries.
x Always load the trailer properly.
x Always secure the load properly with suitable, undamaged straps that can be tightened so
that the load cannot shift.
Driving with a trailer

These dimensions are important because they help determine the way that the forces that arise during
towing are applied to the receiver and its attachments to the vehicle. If you buy a ball mount and ball,
make sure that they meet the following specifications.
Ball mount dimensions
x The drop height (A) from the center of the ball to the center of the hole for the securing pin on the
ball mount must be at least 1 inch (25.4 mm) and at most 27/8 inches (73 mm).
x The pin-to-ball distance (B) from the center of the ball to the center of the hole for the securing pin
on the ball mount must be no more than 7 inches (178 mm).
x The ball diameter must be no more than 11/4 inches (32 mm).
A ball mount and ball combination that does not meet these specifications can damage your vehicle
and may even fail in use ⇒ .
Never install a “weight distributing” or “load equalizing” trailer hitch on your vehicle. The vehicle is not
designed for this kind of trailer hitch ⇒ .
WARNING
An improperly installed or unsuitable trailer hitch can cause the trailer to separate from the
towing vehicle and result in a major accident with serious personal injuries.
x Have any trailer hitch retrofit or other work on a trailer hitch done by a qualified workshop.
CAUTION
The ball mount sticks out behind the rear bumper and can cause injury to pedestrians and
cyclists.
x To reduce the risk of injury in rear-end collisions, and the risk to pedestrians and cyclists
when the vehicle is parked, always remove the ball carrier when you are not towing a trailer.
NOTICE
x Never use a ball larger than 11/4 inches (32 mm) on your vehicle. The vehicle was not
designed to tow heavier trailers with a receiver larger than the specified ball. The increased
loads can damage the attachment points for the trailer hitch.
x Never use an adapter to increase the size of the trailer hitch receiver from 11/4 inches
(32 mm) to 2 inches (50.8 mm) or more to tow a trailer that is heavier than the maximum
permissible trailer weight that your vehicle can tow.
x You can use an adapter if required for the proper installation of a bicycle rack or other
similar carrier as long as the maximum weight limits are observed. When using bicycle racks
or similar carriers, make sure that the rear lights are not blocked.
x Only use trailer hitches that are approved by the hitch manufacturer for your vehicle and
model.

you must work under the vehicle with the wheels on the ground, always make sure that the
vehicle is on level ground, that all 4 wheels are chocked to keep them from moving, and that
the key is not in the ignition.
x If you must work under a vehicle raised on a floor jack, always make sure that the vehicle
is safely supported on safety stands intended for that purpose that are strong enough to
support the weight of the vehicle. The jack supplied with the vehicle is not strong enough for
this purpose and can collapse causing serious personal injury.

strut will hold the hood up.
Closing the engine hood
x Pull the hood down to overcome the resistance of the gas-pressure strut ⇒ .
x Lower the engine hood by hand until it is about 1 ft. (30 cm) above its latch and then let it drop into
place to latch it. Do not push down on it afterwards!
If the hood does not close completely, open it again and close it properly.
When the hood is properly closed, you can see that it fits flush with the other body parts. The indicator
light in the instrument cluster will go out
WARNING
If the hood is not closed properly, it could fly up and block your view while you are driving.
This can lead to a crash and serious personal injuries.
x After closing the engine hood, check that the hood release lever is properly latched into
the hood latch. The engine hood must be flush with the surrounding auto body parts.
x If you ever notice that the hood latch is not properly secured when the vehicle is moving,
stop at once and close it.
x Never let anyone get in the way of the hood when closing it.
NOTICE
x Make sure the windshield wiper arms are resting on the windshield before you open the
hood. Otherwise, the windshield wipers and the hood may be damaged.
x Always put the windshield wiper arms down against the windshield before driving the
vehicle.
NOTICE
Before opening or closing the engine hood, make sure there is enough room to do so, for
example when the vehicle is in a garage.
