WARNING
•
Only use a time interval that is suitable
in current traffic conditions.
•
A short time interval gives the driver lim-
ited reaction time if an unexpected sit-
uation occurs in traffic.
The number of bars indicating the selected
time interval are shown while the setting is
being made and for several seconds afterward.
A smaller version of the symbol is then shown

WARNING
There may be a significant increase in speed
after the
button has been pressed.
A short press on
in standby mode or a long
press in active mode deactivates cruise con-trol. The set speed is then cleared and cannot
be resumed.
When ACC is activated, the vehicle’s speed
increases by approximately 1 mph (1 km/h)
each additional time
is pressed.
Deactivation due to action by the driverACC is deactivated:•
when the brakes are applied
•
if the gear selector is moved to N
•
if the accelerator pedal is depressed for an
extended period.NOTE
If the accelerator pedal is only depressed for
a short time, such as when passing another
vehicle, ACC is deactivated temporarily and
is reactivated when the pedal is released.Automatic deactivationAdaptive cruise control is linked to other sys-
tems such as ABS, the stability and traction
control system (DSTC), and the Distance Alert
System. If any of these systems are not func-
tioning properly, adaptive cruise control is
automatically deactivated.
In the event of automatic deactivation a signal
will sound and the message

example, wet snow or rain.
The radar sensor and its limitationsThe radar sensor is used by both Adaptive
Cruise Control and the Collision Warning Sys-
tem with Auto-brake. It is designed to detect
cars or larger vehicles driving in the same
direction as your vehicle.
WARNING
Accessories or other objects, such as extra
headlights, must not be installed in front of
the grille.
Modification of the radar sensor could make
its use illegal.The radar sensor's capacity to detect vehicles
ahead is impeded:

IntroductionDistance Alert is part of Adaptive Cruise Con-
trol and is a function that provides information
about the time interval to the vehicle ahead.
Time interval information is only given for a
vehicle that is driving ahead of your vehicle, in
the same lane, and in the same direction. No
information is provided for vehicles driving
toward you, moving very slowly, or at a stand-
still.

A smaller section of the red warning light in the
windshield glows steadily if your vehicle is
closer to the vehicle ahead than the set time
interval.
NOTE
Distance Alert is in active mode while Adap-
tive Cruise Control is active.

Driver Alert System (option)
04``175 Introduction
The Driver Alert System is designed to help a
driver who may be becoming fatigued or who
is inadvertently leaving the lane.
The Driver Alert System consists of two differ-
ent functions that can be switched on together
or separately.•
Driver Alert Control (DAC)
•
Lane Departure Warning (LDW)
When one or both of the functions has been
switched on, it is in standby mode and is acti-
vated when the vehicle exceeds a speed of
40 mph (65 km/h).
The function deactivates if speed goes under
37 mph (60 km/h).
Both functions use a camera that is dependent
on the road/lane being clearly marked by pain-
ted lines on each side.WARNING
The Driver Alert system does not function in
all situations and is designed to be a sup-
plementary aid. It is not, however, intended
to replace the driver’s attention and judge-
ment.
Driver Alert Control (DAC)–general
information
G017332
This function is intended to alert the driver if
his/her driving becomes erratic, such as if the
driver is distracted or fatigued. The camera has
certain limitations, see page 170.
A camera monitors the painted lines marking
the lane in which the vehicle is traveling and
compares the direction of the road with the
driver’s movements of the steering wheel. The
driver is alerted if the vehicle does not follow
the lane smoothly.
NOTE
The camera has certain limitations, see
page 161.
DAC is designed to help detect a slowly chang-
ing driving pattern. It is primarily intended to be
used on main roads and is not meant for use in
city traffic.
WARNING
•
DAC is not intended to extend the dura-
tion of driving. Always plan breaks at
regular intervals to help remain alert.
•
In certain cases, fatigue may not affect
the driver’s behavior. In situations of
this type, no warning will be provided.
Therefore, it is important to take breaks
at regular intervals, regardless of
whether or not DAC has given a warn-
ing.
LimitationsIn certain situations, DAC may provide warn-
ings even if the driver’s driving pattern has not
become erratic.•

General informationEconomical driving conserves natural
resourcesBetter driving economy may be obtained by
thinking ahead, avoiding rapid starts and stops
and adjusting the speed of your vehicle to
immediate traffic conditions.
Observe the following rules:•
Bring the engine to normal operating tem-
perature as soon as possible by driving
with a light foot on the accelerator pedal for
the first few minutes of operation. A cold
engine uses more fuel and is subject to
increased wear.
•
Whenever possible, avoid using the vehicle
for driving short distances. This does not
allow the engine to reach normal operating
temperature.
•
Drive carefully and avoid rapid acceleration
and hard braking.
•
Use the transmission's Drive (D) position
as often as possible and avoid using kick-
down.
•
Do not exceed posted speed limits.
•
Avoid carrying unnecessary items (extra
load) in the vehicle.
•
Maintain correct tire pressure. Check tire
pressure regularly (when tires are cold).
•
Remove snow tires when threat of snow or
ice has ended.
•
Note that roof racks, ski racks, etc,
increase air resistance and also fuel con-
sumption.
•
At highway driving speeds, fuel consump-
tion will be lower with the air conditioning
on and the windows closed than with the
air conditioning off and the windows open.
•
Using the onboard trip computer's fuel
consumption modes can help you learn
how to drive more economically.
Other factors that decrease gas mileage
are:
•
Dirty air cleaner
•
Dirty engine oil and clogged oil filter
•
Dragging brakes
•
Incorrect front end alignment
Some of the above mentioned items and others
are checked at the standard maintenance
intervals.
WARNING
Driving with the trunk open: Driving with
the trunk open could lead to poisonous
exhaust gases entering the passenger com-
partment. If the trunk must be kept open for
any reason, proceed as follows:•
Close the windows
•
Set the ventilation system control to air
flow to floor, windshield and side win-
dows and the blower control to its high-
est setting.
Weight distribution affects handlingAt the specified curb weight your vehicle has a
tendency to understeer, which means that the
steering wheel has to be turned more than
might seem appropriate for the curvature of a
bend. This ensures good stability and reduces
the risk of rear wheel skid. Remember that
these properties can alter with the vehicle load.
The heavier the load in the trunk, the less the
tendency to understeer.Handling, roadholdingVehicle load, tire design and inflation pressure
all affect vehicle handling. Therefore, check
that the tires are inflated to the recommended
pressure according to the vehicle load. See the
"Tire pressure" section. Loads should be dis-
tributed so that capacity weight or maximum
permissible axle loads are not exceeded.

Driving through water•
The vehicle can be driven through water up
to a depth of approximately 10 in. (25 cm),
at a maximum speed of 6 mph (10 km/h).
•
Take particular care when driving through
flowing water.
•
Clean the electrical connections for trailer
wiring after driving in mud or water.
•
When driving through water, maintain low
speed and do not stop in the water.WARNING
After driving through water, press lightly on
the brake pedal to ensure that the brakes
are functioning normally. Water or mud can
make the brake linings slippery, resulting in
delayed braking effect.
CAUTION
•
Engine damage will occur if water is
drawn into the air cleaner.
•
If the vehicle is driven through water
deeper than 10 in (25 cm), water may
enter the differential and the transmis-
sion. This reduces the oil's lubricating
capacity and may shorten the service
life of these components.
•
Do not allow the vehicle to stand in
water up to the door sills longer than
absolutely necessary. This could result
in electrical malfunctions.
•
If the engine has been stopped while the
vehicle is in water, do not attempt to
restart it. Have the vehicle towed out of
the water.
Engine and cooling systemUnder special conditions, for example when
driving in hilly terrain, extreme heat or with
heavy loads, there is a risk that the engine and
cooling system will overheat. Proceed as fol-
lows to avoid overheating the engine.•
Maintain a low speed when driving with a
trailer up long, steep hills.
•
Do not turn the engine off immediately
when stopping after a hard drive.
WARNING
The cooling fan may start or continue to
operate (for up to 6 minutes) after the engine
has been switched off.•
Remove any auxiliary lights from in front of
the grille when driving in hot weather con-
ditions.
•
Do not exceed engine speeds of 4500 rpm
if driving with a trailer in hilly terrain. The oil
temperature could become too high.
Conserving electrical currentKeep the following in mind to help minimize
battery drain:•
When the engine is not running, avoid
using ignition mode II. Many electrical sys-
tems (the audio system, the optional navi-
gation system, power windows, etc) will
function in ignition modes 0 and I. These
modes reduce drain on the battery.
•
Please keep in mind that using systems,
accessories, etc., that consume a great
deal of current when the engine is not run-
ning could result in the battery being com-
pletely drained.
•
The optional 12 volt socket in the trunk
provides electrical current even with the
ignition switched off, which drains the bat-
tery.
