WARNING
The hill-start assist system is not
designed to function as a parking brake and
does not prevent the vehicle from moving
when parked on an incline.
Always engage the parking brake in
addition to shifting to park position P.
On uphill grades the hill‑start assist
system maintains the pressure in the brake
system for approximately one second after
you have released the brake pedal.
Therefore, you can start off smoothly
without the vehicle moving immediately
after releasing the brake pedal.
X Release the brake pedal.
X Apply sufficient pressure to the
accelerator pedal.
! After approximately one second, the
hill‑start assist system stops braking
the vehicle, which then can roll
backwards. If you open the driver’s door
within this time, the hill‑start assist
system is deactivated and a warning
signal sounds.

As an added safety feature, your vehicle has
been equipped with a tire pressure
monitoring system (TPMS) that illuminates
a low tire pressure telltale when one or
more of your tires is significantly
underinflated.
Accordingly, when the low tire pressure
telltale illuminates, you should stop and
check your tires as soon as possible, and
inflate them to the proper pressure.
Driving on a significantly underinflated
tire
causes the tire to overheat and can lead
to tire failure.
Underinflation also reduces fuel
efficiency and tire tread life, and may
affect the vehicle’s handling and stopping
ability. Please note that the TPMS is not a
substitute for proper tire maintenance,
and it is the driver’s responsibility to
maintain correct tire pressure, even if
underinflation has not reached the level to
trigger illumination of the TPMS low tire
pressure telltale.
Your vehicle has also been equipped with a
TPMS malfunction indicator to indicate
when the system is not operating properly.
The TPMS malfunction indicator is
combined with the low tire pressure
telltale. When the system detects a
malfunction, the telltale will flash for
approximately 1 minute and then remain
continuously illuminated.
This sequence will continue upon
subsequent vehicle start-ups as long as the
malfunction exists. When the malfunction
indicator is illuminated, the system may
not be able to detect or signal low tire
pressure as intended.
TPMS malfunctions may occur for a variety
of reasons, including the installation of
incompatible replacement or alternate
tires or wheels on the vehicle that prevent
the TPMS from functioning properly. Always
check the TPMS malfunction telltale after
replacing one or more tires or wheels on
your vehicle to ensure that the replacement or alternate tires and wheels allow the
TPMS to continue to function properly.
i If a condition causing the TPMS to
malfunction develops, it may take up to
10 minutes for the system to signal a
malfunction using the TPMS telltale
flashing and illumination sequence.
The telltale extinguishes after a few
minutes driving if the malfunction has
been corrected.
i Operating radio transmission
equipment (e.g. wireless headsets, two-
way radios) in or near the vehicle could
cause the TPMS to malfunction.

The TIN is a unique identifier which
facilitates
efforts by tire manufactures to
notify purchasers in recall situations or
other safety matters concerning tires and
gives purchasers the means to easily
identify such tires.
The TIN is comprised of “Manufacturer’s
identification mark” ;, “Tire size” =,
“Tire type code” ?, and “Date of
manufacture” A.
i For illustration purposes only. Actual
data on tires are specific to each vehicle
and may vary from data shown in above
illustration.
DOT (Department of Transportation) Tire branding symbol
:
which denotes the
tire meets requirements of the U.S.
Department of Transportation.
Manufacturer’s identification mark Manufacturer’s identification mark

New tires have a mark with two symbols.
Retreaded tires have a mark with four
symbols. For more information on
retreaded tires ( Y page 124).
Tire size Code = indicates the tire size. Tire type code Tire type code
? may, at the option of the
manufacturer, be used as a descriptive
code for identifying significant
characteristics of the tire.
Date of manufacture Date of manufacture
A

center will be glad to assist you.
i For information on speed ratings for
winter tires, see “All-season and winter
tires” ( Y page 137). Winter driving instructions
The
most important rule for slippery or icy
roads is to drive sensibly and to avoid
abrupt acceleration, braking and steering
maneuvers.
When the vehicle is in danger of skidding,
move gear selector lever to neutral
position N. Try to keep the vehicle under
control by corrective steering action.
For information on driving with snow
chains*, see “Snow chains*” (Y page 142). G
WARNING
On slippery road surfaces, never downshift
in order to obtain braking action. This
could result in drive wheel slip and
reduced

vehicle control. Your vehicle’s ABS
will not prevent this type of loss of control.
Road salts and chemicals can adversely
affect braking efficiency. Increased pedal
force may become necessary to produce the
normal braking effect.
Depressing the brake pedal periodically
when traveling at length on salt-strewn
roads can bring road-salt-impaired
braking efficiency back to normal.
If the vehicle is parked after being driven
on salt-treated roads, the braking
efficiency should be tested as soon as
possible after driving is resumed. G
WARNING
Make sure not to endanger any other road
users when carrying out these braking
maneuvers. G
WARNING
If the vehicle becomes stuck in snow, make
sure
snow is kept clear of the exhaust pipe
and from around the vehicle with the engine
running. Otherwise, deadly carbon
monoxide (CO) gases may enter vehicle
interior resulting in unconsciousness and
death.
To assure sufficient fresh air ventilation,
open a window slightly on the side of the
vehicle not facing the wind. G
WARNING
The outside temperature display is not
designed
to serve as an ice-warning device
and is therefore unsuitable for that
purpose. Indicated temperatures just
above the freezing point do not guarantee
that the road surface is free of ice.

(Y page 142). Standing water
! Do not drive through flooded areas or
water of unknown depth. Before driving
through water, determine its depth.
Never accelerate before driving into
water. The bow wave could force water
into the engine and auxiliary
equipment, thus damaging them.
