Driving
Before Driving
Driving Preparation
Check the following items before you start driving.
• Make sure there are no obstructions on the windows, door mirrors, exterior
lights, or other parts of the vehicle.
u Remove any frost, snow, or ice.
u Remove any snow on the roof, as this can slip down and obstruct your field of
vision while driving. If frozen solid , remove ice once it has softened.
u When removing ice from around the wheels, be sure not to damage the wheel
or wheel components.
• Make sure the hood is securely closed.
u If the hood opens while driving, your front view will be blocked.
• Make sure the tires are in good condition.
u Check air pressures, and check for damage and excessive wear.
2Checking and Maintaining Tires P. 614
•Make sure there are no people or ob jects behind or around the vehicle.
u There are blind spots from the inside.
■Exterior Checks1Exterior Checks
NOTICE
When doors are frozen s hut, use warm water around
the door edges to melt any ice. Do not try to force
them open, as this can damage the rubber trim
around the doors. When done, wipe dry to avoid
further freezing.
Do not pour warm water into the key cylinder.
You will be unable to insert the key if the water
freezes in the hole.
Heat from the engine and exhaust can ignite
flammable material s left under the hood, causing a
fire. If you’ve parked y our vehicle for an extended
period, inspect and remove any debris that may have
collected, such as dried grass and leaves that have
fallen or have been carried in for use as a nest by a
small animal. Also, check under the hood for leftover
flammable materials after you or someone else has
performed maintenance on your vehicle.

Towing a Trailer
Towing Preparation
Your vehicle can tow a trailer if you carefully observe the load limits, use the proper
equipment, and follow the towing guidelin es. Check the load limits before driving.
■Total trailer weight
Do not exceed the maximum allowable
weight of the trailer, cargo, and everything in
or on it shown in the table. Towing loads in
excess of this can seriously affect vehicle
handling and performance and can damage
the engine and drivetrain.
Each weight limit is calculated based on the following conditions:
• Occupants fill seats from the front of the vehicle to the back
• Each occupant weighs 150 lbs (68 kg)
• Each occupant has 17.6 lbs (8 kg) cargo in the cargo area.
Any additional weight, cargo or accessories reduce the maximum trailer weight and
maximum tongue load.
■Towing Load Limits1 Towing Load Limits
Check if all loads are within limits at a public scale.
If a public scale is not av ailable, add the estimated
weight of your cargo load to the weight of your
trailer (as quoted by th e manufacturer), and the
tongue load.
When using a detachable towing device, always
remove the towing device when not in use and only
install it when towing so that it does not cover or hide
anything on the rear of your vehicle, such as the
exterior lights or licence plate.
Break-in Period.
Avoid towing a trailer duri ng your vehicle’s first 600
miles (1,000 km).
Never exceed the gross weight ratings.
Gross weight information 2 Vehicle Specifications P. 690
3WARNING
Exceeding any load limit or improperly
loading your vehicle and trailer can cause a
crash in which you can be seriously hurt or
killed.
Check the loading of your vehicle and
trailer carefully before starting to drive.

When Driving
Starting the Engine
1.Make sure the parkin g brake is applied.
u The Parking Brake and Brake System
indicator (red) comes on for 30 seconds
when you press the electric parking
brake switch.
2. Depress the brake pedal.
3. Press the ENGINE START/STOP button
without depressing the accelerator pedal.1 Starting the Engine
Keep your foot firmly on the brake pedal when
starting the engine.
The engine is harder to st art in cold weather and in
thinner air found at altit udes above 8,000 feet (2,400
meters).
When starting the engine in cold weather, turn off all
electrical accessories such as the lights, climate
control system, and rear de fogger in order to reduce
battery drain.
If you live in a region where winter is extremely cold,
an engine block heater will improve starting and
warming of the engine. Consult a dealer for details.
If the exhaust system sounds abnormal or you can
smell exhaust gas inside the vehicle, have your vehicle
checked by a dealer. There may be a problem with
the engine or exhaust system.
Bring the keyless remote close to the ENGINE

remote is weak. 2 If the Keyless Remote Battery is Weak

uuBraking uBrake System
Driving
Your vehicle is equipped with disc brakes at all four wheels. The brake assist system
increases the stopping force when you depress the brake pedal hard in an
emergency situation. The an ti-lock brake system (ABS) helps you retain steering
control when brak ing very hard.
2Brake Assist System P. 554
2 Anti-lock Brake System (ABS) P. 553
■Foot Brake1Foot Brake
Check the brakes after driving through deep water,
or if there is a buildup of road surface water. If
necessary, dry the brakes by lightly depressing the
pedal several times.
If you hear a continuous me tallic friction sound when
applying the brakes, this is caused by the brake wear
indicator rubbing on the brake rotor and indicates
that the brake pads need to be replaced. Have the
vehicle checked by a deal er. If you hear only an
occasional squeak or squeal when you initially apply
the brake pedal, this may be normal and caused by
high frequency vibr ation of the brake pads against
the rotating brake disc.
Constantly using the brake pedal while going down a
long hill builds up heat, which reduces the brake
effectiveness. Apply engine braking by taking your
foot off the accelerator pe dal and downshifting to a
lower gear.
Do not rest your foot on the brake pedal while
driving, as it will lightly apply the brakes and cause
them to lose effectiveness over time and reduce pad
life. It will also conf use drivers behind you.
Whenever the brakes are activated by CMBS
TM or
another system that automa tically controls braking,
the brake pedal is depressed and released in
accordance with braking function.
