D (Drive)
This is the normal driving position. The
transmission will automatically shift
through a 8-gear sequence, providing
the best fuel economy and power.
To start the vehicle forward, push the D
(Drive) button by depressing the brake
pedal with the engine ON. Then depress
the accelerator pedal smoothly. For extra
power when passing another vehicle or
driving uphill, depress the accelerator
fully. The transmission will automatically
downshift to the next lower gear (or
gears, as appropriate). When the vehicle
is stopped in D (Drive) position, if you
open the driver’s door with the seat belt
unfastened, the gear is shifted to P (Park)
position automatically.
However when the vehicle moves in D
(Drive) position, if you open the driver’s
door with the seat belt unfastened,
the gear may be not shifted to P (Park)
position automatically for protecting the
dual clutch transmission.
The DRIVE MODE switch, located on
the shift lever/button console, allows
the driver to switch from NORMAL/
COMFORT mode to SPORT or ECO mode. (if equipped)
For more details, refer to “Drive Mode
Integrated Control System” later in this
chapter. Shift-lock system
For your safety, the automatic
transmission has a shift-lock system
which prevents shifting the transmission
from P (Park) or N (Neutral) to R
(Reverse) or D (Drive) unless the brake
pedal is depressed.
To shift the transmission from P (Park)
into R (Reverse):
1. Depress and hold the brake pedal.
2. Start the engine or place the ignition
switch in the ON position.
3. Depress the brake pedal and move the shift lever to R (Reverse). (shift lever
type)
Depress the brake pedal and push the
R (Reverse) button. (shift button type)
When the battery is discharged:
You cannot shift the shift lever/button,
when the battery is discharged.
In emergencies, do the following
to move the shift lever/button to N
(Neutral) on a level ground.
1. Connect the battery cables from another vehicle or from a another
battery to the jump-starting terminals
inside the engine compartment.
For more details, refer to “Jump
Starting” in chapter 8.
2. Release the parking brake with the ignition switch in the ON position.
3. Shift the gear to the N(Neutral) position refer to the “Stay in Neutral
when vehicle is Off” in this chapter.

Engine Coolant
The coolant should be changed at the
intervals specified in the maintenance schedule.
Automatic Transmission Fluid
Automatic Transmission Fluid should
be replaced by an authorized HYUNDAI
dealer at the intervals specified in the
maintenance schedule.
Information
Automatic transmission fluid color is red
when new. As the vehicle is driven, the automatic transmission fluid will begin to look
darker. This is a normal condition and you
should not judge the need to replace the
fluid based upon the changed color.
NOTICE
The use of a non-specified fluid could
result in transmission malfunction
and failure. Use only the specified
automatic transmission fluid (refer
to “Recommended Lubricants and
Capacities” in chapter 2).
Brake Hoses and Lines
Visually check for proper installation,
chafing, cracks, deterioration and any
leakage. Replace any deteriorated or
damaged parts immediately.
Brake Fluid
Check the brake fluid level in the brake
fluid reservoir. The level should be
between the MIN and the MAX marks
on the side of the reservoir. Use only
hydraulic brake fluid conforming to DOT
4 specification.
Parking Brake
Inspect the parking brake system
including the parking brake pedal and cables.
Dual clutch transmission fluid (if equipped)
Inspect the dual clutch transmission fluid
according to the maintenance schedule.
Brake Discs, Pads, Calipers and
Rotors
Check the pads for excessive wear, discs
for run out and wear, and calipers for
fluid leakage.
Exhaust Pipe and Muffler
Visually inspect the exhaust pipes,
muffler and hangers for cracks,
deterioration, or damage. Start
the engine and listen carefully for
any exhaust gas leakage. Tighten
connections or replace parts as
necessary.
