Trailer towing

Trailer towing
Driving with a trailer
ere eleurl lela)
Your vehicle is primarily intended for transport-
ing people and luggage. However, if you drive
with a trailer, follow the technical requirements,
the operation and driving tips, and the legal reg-
ulations.
Driving with a trailer affects the vehicle's energy
usage, performance, and wear. It also requires
higher concentration from the driver.

ZA WARNING
Do not transport any people in a trailer due to
the risk of fatal injury.
Technical requirements
Trailer hitch

Only use a trailer hitch with a removable ball
hitch mount and ball hitch. The trailer hitch must
be permitted for the vehicle, the trailer and the
permitted total weight of the trailer being
pulled. Above all, it must be securely and safely
attached to the vehicle trailer.
Never mount a trailer hitch on the bumper. The
trailer hitch must be mounted in a way that does
not impair the function of the bumper. Do not
make any changes to the exhaust system and the
brake system.
Check regularly if the trailer hitch is securely
mounted. Always follow the instructions given by
the trailer hitch manufacturer.
Trailer brakes
If the trailer has its own brake system, then fol-
low the manufacturer specifications. However,
the brake system on the trailer must never be
connected to the vehicle brake system.
Engine cooling system
Driving with a trailer means a higher load on the
engine and the cooling system. The cooling sys-
tem must be designed for additional load and
contain enough coolant >@®.
102

Z\ WARNING
— Never mount a "weight-distributing" or
"load-balancing" trailer coupler as the trailer
hitch. The vehicle was not designed for
these types of trailer hitches. The trailer
hitch can malfunction and the trailer can
break off from the vehicle.
— If the trailer is equipped with electronic
brakes, these brakes cannot be activated by
a factory-installed control system, which in-
creases the risk of an accident.
—To reduce the risk of injury, always remove
the ball hitch mount if no trailer is mount-
ed
@) Note
Longer inclines cannot be driven without a
suitable cooling system, especially if the out-
side temperatures are high. Otherwise, this
increases the risk of engine damage.
ey Teale met ada)
Towing capacity

Never exceed the maximum permitted weights
=> page 262.
In some scenarios, the load in trailer mode can
be reduced due to the permitted towing weight.
You can drive up larger inclines if you are not us-
ing the maximum towing capacity.
The specified towing weights only apply at eleva-
tions up to 3,200 ft (1,000 m) above sea level. As
the elevation increases, the motor power de-
creases due to the decreasing air pressure. This
reduces the hill climbing ability and towing ca-
pacity. For every additional 3,200 ft (1,000 m),
the maximum permitted towing weight must be
reduced by approximately 10%. The permitted
towing weight is the combined weight of the
(loaded) vehicle and the (loaded) trailer.
Tongue weight
The maximum permitted tongue weight of the
trailer drawbar on the trailer hitch ball head must
not be exceeded.

Trailer towing

there are unfavorable road, weather, and/or wind
conditions. This especially applies when driving
downhill.
Hill
When you start driving uphill or downhill, trailers
may tilt or sway sooner than when driving ona
level surface. If small swaying movements have
already occurred, you can stabilize the trailer by
firmly braking immediately. Never attempt to
“straighten out” the trailer by accelerating.
Downshift before driving on hills to utilize the en-
gine braking effect > A\.
Brakes
When using a trailer with overrun brakes, first
brake gently then quickly. This reduces the risk of
jerking while braking if the trailer wheels lock up.
Engine coolant temperature
Pay attention specifically to the coolant tempera-
ture display when there are high outside temper-
atures, and when driving on long inclines
= page 13. Shift to a higher gear in a timely man-
ner.

Z\ WARNING
Constant braking causes the brakes to over-
heat and can substantially reduce braking per-
formance, increase braking distance, or cause
complete failure of the brake system.

Cruise control system
Applies to: vehicles with cruise control system
The cruise control system assists the driver in
maintaining a constant speed above approxi-
mately 15 mph (20 km/h). The system maintains
the desired speed by braking and accelerating.

ZA\ WARNING
— Always pay attention to the traffic around
your vehicle when the cruise control system
is in operation. As the driver, you are always
responsible for controlling your vehicle
speed and the distance between your vehicle
and
other vehicles.
— For safety reasons, cruise control should not
be used in the city, in stop-and-go traffic, on
winding roads, and when road conditions are
poor (such as ice, fog, gravel, heavy rain,
and conditions that could lead to hydroplan-
ing), because this increases the risk of an ac-
cident.
— Switch the cruise control off temporarily
when driving in turning lanes, highway exits,
or in construction zones.
—To reduce the risk of an accident, you should
only resume the stored speed if it is suitable
for the current traffic conditions.


() Note
Before driving downhill a long distance ona
steep hill, decrease your speed and select a
lower gear. This makes use of the engine brak-
ing effect and reduces the load placed on the
brakes.
@) Tips
The brake lights turn on when the brakes are
applied automatically.

Adaptive speed/cruise
assist
General information
Applies to: vehicles with adaptive cruise assist
Depending on the vehicle equipment, the adap-
tive cruise assist may consist of the following
functions:
The adaptive speed/cruise assist (called only
adaptive cruise assist in the vehicle display and in
the rest of the Owner's Manual) consists of a
speed and distance control system. It assists the
driver by both regulating the speed and main-
taining the set distance to the vehicle driving
ahead, within the limits of the system. If the sys-
tem detects a vehicle driving ahead, the adaptive
cruise assist can brake and accelerate your vehi-
cle within the limits of the system. On open roads
with no traffic, it functions like a cruise control
system. The stored speed is maintained. When
approaching a vehicle driving ahead, the adaptive
cruise assist automatically brakes to match that
vehicle's speed and then maintains the set dis-
tance as much as possible. As soon as the system
does not detect a vehicle driving ahead, adaptive
cruise assist accelerates up to the set speed.

In stop-and-go traffic, the vehicle may brake to a
full stop and then may also start driving again
automatically under certain conditions.


Follow the safety precautions and note the
limits of the assist systems, sensors, and
cameras > page 105.


For an explanation on conformity with the
FCC regulations in the United States and the
Industry Canada regulations, see > page 259.

Fig. 91 Example: vehicle changing lanes and stationary ve-
hicle


Fig. 92 Example: driving into a curve
In some situations, the adaptive cruise assist
function is limited and you must assume control
of the vehicle when necessary, for example by ap-
plying the brakes.
— If a vehicle that was already detected (@ turns
or changes lanes, the adaptive cruise assist will
react to the vehicle ahead of it @).

— When driving into a curve > fig. 92 and out of a
curve, the adaptive cruise assist may react to a
vehicle in the adjacent lane and apply the
brakes. You can override the system by pressing
the accelerator pedal briefly.
— The adaptive cruise assist works with the vari-
ous sensors and cameras in the vehicle.
Vehicles can only be detected once they are
within the area and range covered by the sen-
sors > page 106.
— When driving around tight curves, a vehicle
driving ahead that was previously detected may
no longer be detected, and the adaptive cruise
assist may accelerate unexpectedly.
— The adaptive cruise assist does not react toa
stationary vehicle in the same lane if the sys-
tem expects that you can easily drive around
the stationary vehicle by turning the steering
wheel.
— The adaptive cruise assist may not react to sta-
tionary obstacles, such as the end of a traffic
jam, especially at high speeds.
— The adaptive cruise assist has a limited ability
to detect vehicles that are a short distance
ahead, off to the side of your vehicle, or moving
into your lane.
— Objects that are difficult to detect, such as mo-
torcycles, vehicles with high ground clearance,
or vehicles with an overhanging load, may be
detected late or not detected at all.
— The adaptive cruise assist does not respond to
people, animals, or objects that are crossing or
approaching from the opposite direction.

Follow the safety precautions and note the
limits of the assist systems, sensors, and
cameras > page 105.

responsible for controlling the vehicle. The
driver is especially responsible for braking,
starting to drive, controlling the speed, and
maintaining the distance to other vehicles.
— Turn on the adaptive cruise assist only if the
surrounding conditions permit it. Always
adapt your driving style to the current visu-
al, weather, road, and traffic conditions.
— Switch the adaptive cruise assist off tempo-
rarily when driving in turning lanes or high-
way exits. This prevents the vehicle from ac-
celerating to the stored speed when in these
situations.

ZA WARNING
If you press the SETK2) button when driving
at speeds below 20 mph (30 km/h), then 20
mph (30 km/h) will be set because that is the
minimum speed that can be set. If no vehicle
is detected ahead of you, the vehicle will ac-
celerate up to that speed.


@ Tips
— Always keep your hands on the steering
wheel. The driver is always responsible for
adhering to the regulations applicable in
the country where the vehicle is being oper-
ated.
— If you switch the ignition or the adaptive
cruise assist off, the stored speed is erased
for safety reasons.
— When the adaptive cruise assist is switched
on, the ESC and the ASR are switched on au-
tomatically.
— The system cannot be switched off if the
road exceeds the maximum possible grade
for safe operation.
— If you signal to pass and the adaptive cruise
assist suggests a passing maneuver, the
adaptive cruise assist will accelerate just be-
fore changing lanes to shorten the distance
to the vehicle driving ahead.

Setting the distance
Applies to: vehicles with adaptive cruise assist

B4M-0234


Fig. 97 Operating lever: setting the distance
If you adjust the speed, you must also change the
time gap to the vehicle driving ahead. The higher
the speed, the greater the distance that is need-
ed.
> Tap the rocker switch to display the distance
that is currently set.
> To increase or decrease the distance in incre-
ments, tap the switch again toward G) or ().
The newly-set distance will be shown briefly, for
example with the indicator light. In the Driv-
er assistance display, a graphic display is shown
instead of the indicator lights > page 114,
fig. 94. The display matches the functions of the
indicator lights.
When approaching a vehicle driving ahead, the
adaptive cruise assist brakes to the set speed and
then maintains the set distance. If the vehicle
driving ahead accelerates, then the adaptive
cruise assist will also accelerate up to the speed
that you have set.
The following distances can be set:
