Driving and Operating 197.
Be alert on top of hills;
something could be in your lane
(e.g., stalled car, accident).
.
Pay attention to special road
signs (e.g., falling rocks area,
winding roads, long grades,
passing or no-passing zones)
and take appropriate action.
Winter Driving Driving on Snow or Ice Snow or ice between the tires and
the road creates less traction or
grip, so drive carefully. Wet ice can
occur at about 0 °C (32 °F) when
freezing rain begins to fall. Avoid
driving on wet ice or in freezing rain
until roads can be treated.
For slippery road driving:
.
Accelerate gently. Accelerating
too quickly causes the wheels to
spin and makes the surface
under the tires slick.
.
Turn on Traction Control. See
Traction Control/Electronic
Stability Control 0 217 . .
Antilock Brake System (ABS)
improves vehicle stability during
hard stops, but the brakes
should be applied sooner than
when on dry pavement. See
Antilock Brake System
(ABS) 0 214 .
See Driver Mode Control 0 219
.
Allow greater following distance
and watch for slippery spots. Icy
patches can occur on otherwise
clear roads in shaded areas.
The surface of a curve or an
overpass can remain icy when
the surrounding roads are clear.
Avoid sudden steering
maneuvers and braking while
on ice.
.
Turn off cruise control.
Blizzard Conditions
Stop the vehicle in a safe place and
signal for help. Stay with the vehicle
unless there is help nearby.
If possible, use Roadside Service.
See Roadside Service 0 364 . To get
help and keep everyone in the
vehicle safe: .
Turn on the hazard warning
flashers.
.
Tie a red cloth to an outside
mirror.
{ WarningSnow can trap engine exhaust
under the vehicle. This may
cause exhaust gases to get
inside. Engine exhaust contains
carbon monoxide (CO), which
cannot be seen or smelled. It can
cause unconsciousness and even
death.
If the vehicle is stuck in snow:
.
Clear snow from the base of
the vehicle, especially any
blocking the exhaust pipe.
.
Open a window about 5 cm
(2 in) on the vehicle side
that is away from the wind,
to bring in fresh air.
.
Fully open the air outlets on
or under the instrument
panel.

that the vehicle is approaching a
pedestrian ahead much too quickly,
the box changes to red.
With the Front Pedestrian Braking
system turned on, Night Vision
provides a red Head-Up Display
(HUD) alert when the system
detects that the vehicle is
approaching a pedestrian ahead
much too quickly. In addition, an
alert beeps or the Safety Alert Seat
pulses, if equipped. See Front
Pedestrian Braking (FPB)
System 0 241 . { WarningThe system does not detect all
objects or the vehicle distance
from objects. The system may not
provide a warning with enough
time to help avoid a crash.
1. Low-Beam Headlamps
2. High-Beam Headlamps
3. Night Vision System By selecting a view on the
instrument cluster, the Night Vision
image can be displayed. See
Instrument Cluster (Uplevel) 0 121
or Instrument Cluster (Base Level)
0 118 . The Night Vision system can
operate only if:
.
The ignition is on.
.
The vehicle is in P (Park) or a
forward gear.
.
It is dark enough outside.
.
The headlamps are on.
Adjust the instrument panel
brightness to make the image no
brighter than necessary. Turn the
image off by selecting another view
on the instrument cluster.
Warm objects, such as pedestrians,
animals, and other moving vehicles,
should appear whiter on the Night
Vision display. Cold objects, such as
the sky, signs, and parked vehicles,
should appear darker. Night Vision
only shows objects that are warmer
or colder than the surroundings.
It does not detect brake lamps, turn
signals, emergency flashers, traffic
lights, or sign information.

256 Driving and Operating .
Do not tow a trailer during the
first 2 414 km (1,500 mi) to
prevent damage to the engine,
axle, or other parts.
.
Then during the first 800 km
(500 mi) of trailer towing, do not
drive over 80 km/h (50 mph) and
do not make starts at full throttle.
.
Vehicles can tow in D (Drive).
Shift the transmission to a lower
gear if the transmission shifts
too often under heavy loads and/
or hilly conditions.
.
Do not use Adaptive Cruise
Control when towing.
.
The Front Automatic Braking
System should be set to Off
when towing. See Front
Automatic Braking (FAB)
System 0 240 .
.
Turn off Parking Assist when
towing. { WarningWhen towing a trailer, exhaust
gases may collect at the rear of
the vehicle and enter if the
liftgate, trunk/hatch, or rear-most
window is open.
When towing a trailer:
.
Do not drive with the
liftgate, trunk/hatch,
or rear-most window open.
.
Fully open the air outlets on
or under the instrument
panel.
.
Also adjust the climate
control system to a setting
that brings in only outside
air. See “ Climate Control
Systems ” in the Index.
For more information about
carbon monoxide, see Engine
Exhaust 0 209 .
Towing a trailer requires a certain
amount of experience. The
combination you are driving is
longer and not as responsive as the vehicle itself. Get acquainted with
the handling and braking of the rig
before setting out for the open road.
Before starting, check all trailer hitch
parts and attachments, safety
chains, electrical connectors, lamps,
tires, and mirrors. If the trailer has
electric brakes, start the
combination moving and then apply
the trailer brake controller by hand
to be sure the brakes work.
During the trip, check occasionally
to be sure that the load is secure
and the lamps and any trailer
brakes still work.
Following Distance Stay at least twice as far behind the
vehicle ahead as you would when
driving the vehicle without a trailer.
This can help to avoid heavy
braking and sudden turns.
Passing
More passing distance is needed
when towing a trailer. The
combination will not accelerate as
quickly and is longer so it is

264 Vehicle Care Keep a record with all parts receipts
and list the mileage and the date of
any service work performed. See
Maintenance Records 0 356 .
CautionEven small amounts of
contamination can cause damage
to vehicle systems. Do not allow
contaminants to contact the fluids,
reservoir caps, or dipsticks.
Hood
{ WarningGas struts and other hot metal
components under the hood can
get hot after running the engine.
Do not touch as they can burn
unprotected skin and could cause
serious injury.
Clear any snow from the hood
before opening. To open the hood:
1. Pull the hood release handle.
It is on the lower left side of the
instrument panel between the
door and the steering wheel.
2. Release the handle, then pull
the handle again to fully open
the hood.
3. Go to the front of the vehicle
and lift the hood open. CautionBe sure the hood is completely
closed before driving. Damage
may occur if it is not.
To close the hood:
1. Before closing the hood, be
sure all filler caps are properly
installed.
2. Lower the hood approximately
46 cm (18 in) from the closed
position.
3. Then push the front center of
the hood with a swift, firm
motion.
4. Check to make sure the hood

290 Vehicle Care Always clear ice and heavy snow
from the windshield before using the
windshield wipers.
If the overload is caused by an
electrical problem and not snow or
ice, be sure to get it fixed.
Fuses and Circuit
Breakers The wiring circuits in the vehicle are
protected from short circuits by a
combination of fuses and circuit
breakers. This greatly reduces the
chance of damage caused by
electrical problems.
To check a fuse, look at the
silver-colored band inside the fuse.
If the band is broken or melted,
replace the fuse. Be sure to replace
a bad fuse with a new one of the
identical size and rating.
Fuses of the same amperage can
be temporarily borrowed from
another fuse location, if a fuse goes
out. Replace the fuse as soon as
possible. To identify and check fuses, circuit
breakers, and relays, see Engine
Compartment Fuse Block 0 290 ,
Instrument Panel Fuse Block 0 293 ,
and Rear Compartment Fuse
Block 0 295 .
Engine Compartment
Fuse Block The underhood fuse block is on the
driver side of the engine
compartment.
Lift the fuse block cover to access
the fuses. The vehicle may not be equipped
with all of the fuses and relays
shown.
CautionSpilling liquid on any electrical
component on the vehicle may
damage it. Always keep the
covers on any electrical
component.
